Pioneer upgrades SMA wireless speaker systems with vTuner Internet radio

Firmware Download Site

My Comments

I have previously written an article about the Pioneer XW-SMA series of Wi-Fi-capable wireless speakers which can play music from your mobile device or laptop using either AirPlay or DLNA technologies. These can work as their own access points if you don’t have access to a Wi-Fi segment that can work across many devices like a home network.

But Pioneer has extended the functionality of all of these speakers by integrating vTuner internet radio functionality. You can add this functionality on to these speakers by performing a firmware upgrade.

Here, you have to download the latest firmware file from Pioneer’s Web site and upload it to the speaker via its management Web page that you discover through the Bonjour device list in Safari or the Network option in Windows Explorer. Here you have an option to open the device Webpage for each of the devices.

But how do you select the Internet-radio stations where the speakers don’t have a display? Here, you have to install the Pioneer ControlApp program on your iOS or Android mobile device and select the stations using that app. This is in a similar manner to what Sony are doing for their wireless speakers where they use a remote-control app on a mobile-computing device to control the speakers.

Of course, you would need to have the speaker connected to a network that has access to the Internet without the need for a login page when you want to listen to Internet radio. For best results on the road with a wireless-broadband connection, I would recommend using a “Mi-Fi” device.

Holden to add smartphone-linked network audio to their cars

Holden Adds Stitcher To Its Infotainment Systems, Pandora And TuneIn On The Way | Gizmodo Australia

My Comments

Previously I have covered the issue of Internet radio and networked audio in the automotive context and raised the possible scenarios that apply to this application. They were either a smartphone or MiFi device acting as a network router between a mobile broadband service and a Wi-Fi segment in the car with the car radio being an Internet radio; a car infotainment system with an integrated mobile broadband router; or a smartphone or tablet with the appropriate app working as an Internet radio or network audio endpoint and connected to the car stereo typically via USB, Bluetooth or line-level connection.

Vehicle builders and, to some extent, car-audio manufacturers are implementing a two-way setup which integrates the smartphone with the car infotainment system. In most cases, the link would be fulfilled by a Bluetooth wireless connection for control, communications audio and entertainment audio and, depending on the setup, an interface app installed on the iOS or Android smartphone that works with particular information, music and other apps.

Holden, like most of the GM nameplates around the world, have followed this path for their infotainment by introducing the MyLink system to the Barina CDX small car. Here, this would require the use of an iOS or Android smartphone with a bridge app linked by Bluetooth to the car. But the phone would be managed at least using the touchscreen on the dashboard. Initially the Holden solution is to work with the Stitcher Internet-radio platform but they are intending to have it work with Pandora and TuneIn Radio.

There is an intent to allow you to work your smartphone platform’s navigation function on the dash using the “BringGo” software so you are not needing to have the phone on a “cobra mount” if you want to use Google Maps or Apple Maps.

What I see of this is that vehicle builders are integrating your smartphone or tablet as a part of the vehicle not just for communications but for information, entertainment and navigation.

Network-capable speaker units–now coming as a torrent

Revo Domino Internet radio

Revo Domino – an example of an Internet radio with DLNA Media Playback

Regular readers of this site would have noticed the Internet radios that I have reviewed earlier on. These were typically tabletop radios that had a broadcast tuner capable of receiving at least FM and / or DAB digital broadcast radio. But they had Wi-Fi and, in some cases, Ethernet network connectivity which allowed them access to, most commonly, the vTuner Internet-radio directory and the ability to play through audio content from any broadcaster that listed its stream in this directory. They also had the ability to play audio content held on a DLNA media server after it was selected on the set’s control surface.

Of course, all of these sets had a line input so they can amplify other audio equipment like portable CD players but most of them had a dock for one of Apple’s iPod or iPhone mobile devices. A few of the sets even had a USB connection so you can play music held on a USB memory key.

Now the network-audio direction is coming in the form of network-capable speaker units that have Apple Airplay and, increasingly, DLNA Media-Renderer operating mode. This meant that you could use software running to these protocols to play music held on a computer, smartphone or tablet through these systems as explained in this feature article. The network connectivity for all of them is Wi-Fi to 802.11g/n standards with WPS “push-push” setup but some of these units would have an Ethernet socket for connection to an Ethernet or HomePlug network segment and / or Wi-Fi Direct so they can become their own access point for smartphones and tablets.

The manufacturers are running a range of two or three units with similar functionality but having differing speaker configurations and / or power outputs with some having the capability to offer a “punchy” sound where that tight bass does exist. As well, one or two of the models in these ranges is equipped with a rechargeable battery pack and designed for portability so they can be used on the beach or on the streets in a similar manner to those classic “ghetto-blasters” of the 1980s.

Pioneer NAC-3 Internet radio and iPod dock

Pioneer NAC-3 Internet radio and iPod dock – capable of being controlled by a DLNA control point program

The device that predicted this level of functionality in a network speaker system was, in my opinion, the Pioneer XW-NAC3 speaker dock / Internet radio that I reviewed on this site. Here, it had Wi-Fi and Ethernet connectivity as well as support for Bluetooth A2DP audio streaming. But it used the network connectivity to play broadcast content from Internet-radio stations on the vTuner directory as well as being able to be controlled by a DLNA Media Control Point alongside the basic DLNA MediaPlayer “play-from-own-control-surface” functionality.

Usage Issues

A problem I have discovered with some DLNA server / control point software running on Android devices is that they won’t work properly if you run the device as its own access point. This would be something that you may do if you enable “Wi-Fi tethering” on your phone to share your phone’s Internet access and data allowance with other devices.

Here, you may have to work around this by using another access point to create the temporary Wi-Fi segment. This could be done using an ordinary Wi-Fi router, even one of those “Mi-Fi” devices that work as a router for a wireless-broadband service. This solution may come in to its own with the battery-driven units that don’t have Wi-Fi Direct and you want to play content from your mobile device or laptop.

Another situation that may plague anyone who sets these units up in premises with a public Wi-Fi hotspot is that they may not work properly with these hotspots. Here, most of these public-access networks would be set up for client isolation so that no other client devices can discover each other. As well, most such networks typically use a Web interface for provisioning the Internet service. This will typically make the network unusable for point-to-point use like media playback.

Instead, if you are using that network speaker system in that hotel room or serviced apartment which has a public-access or guest-access wireless hotspot, use a “MiFi” or a similar device to create a Wi-Fi network if the computer, smartphone or speaker system doesn’t support Wi-Fi Direct. Some Wi-Fi Direct setups like the Intel implementations used for laptop computers may allow you to work the temporary network in conjunction with the public-access network and bridge Internet data to this temporary network. This would come in handy with units that offer Internet-radio functionality like the Pioneer NAC-3 or the Denon Cocoon series.

What to look for with these speaker systems

I would make sure that if you are intending to use these network speaker system with a smartphone, tablet or PC, make sure that the unit works with DLNA and Apple AirPlay.

If the speaker unit that you are after doesn’t have Wi-Fi Direct, you may have to make sure you have it working with a wireless access point like your home network’s WiFi router or a “MiFi” when you are using it on a wireless network.

Also pay attention to the sound quality and the functionality of these speakers, especially if you buy units that you intend to use “at home”. As for portable units, look for anything that also works for durability especially if they are intended to be used on the beach or by the pool.

Once you choose the right network-capable speaker system for yourself or to give as a gift, you could then end up enjoying listening to them for a long time.

Online rights for sports and cultural events–what could be done?

15/02/2012 IP-based broadcasting No Comments

After hearing the latest furore about Optus delivering delayed broadcasts of the AFL and NRL football matches to their mobile subscribers, I have thought that something needs to be done concerning how online and mobile rights for sporting and cultural events are worked out.

Typically the online and mobile rights for these events are bought by ISPs or mobile carriers for exclusive distribution to their subscribers. This has become a thorn in the side of sports and cultural bodies, existing radio / TV broadcasters and similar groups due to various limitations that could exist.

For example, most radio stations run an Internet-hosted simulcast of their regular broadcast and this has extended radio to the iPhone and popularised the Internet radios such as the ones I have reviewed on this site. What has happened lately is that radio stations that call AFL or NRL football matches using their own talent have had to run alternate programming on their Internet feeds so as to placate Telstra who have exclusive rights to these matches.

Similarly, Optus running a broadcast-IP setup and cloud-recording arrangement to deliver the football to their subscribers has ruffled Telstra’s and the football leagues’ feathers.

This can cause issues not just with ISPs and mobile providers but can affect companies who deliver any form of IPTV services which is a growing trend with the arrival of next-generation broadband services. It could even extend to usage environments such as hotels and apartment blocks implementing “broadcast-IP” tuners to deliver broadcast content from a rooftop aerial to the building’s LAN with Internet-enabled radio / TV equipment connected to the network showing or playing the content.

What needs to be looked at for defining online rights to a sporting or cultural event is whether the online use is simply a verbatim use of an existing radio or television broadcast or data available on the scoreboard; or whether it is an extended mixed-media interactive use of the content. The “verbatim use” would be something like diffusing broadcasts from a broadccast-IP tuner to a broadcaster simulcasting an audio or video feed of the broadcast to the Internet and providing a user-interface just to gain access to that stream. It can also encompass someone who writes a mobile scoreboard app with their own interface.

This is compared to an enhanced online service with extra data on the game being provided alongside the broadcast of that game, such as on-demand video, a Web scoreboard or a highly-strung scoreboard app with the leagues’ logos.

Here online / mobile rights could be split in to two categories – a default simulcast rights for existing broadcasters which requires verbatim use of the sportscast including all commercial and continuity material normally broadcast; and an enhanced online right for online providers who buy that right. The latter right should then enable access to the content by users associated with competing Internet and mobile providers under the same terms as the rights-holder’s subscribers. There could also be a raw-data right for people who prepare their own data applications like sports-magazine Websites and online scoreboard apps.

For the league or cultural-event organiser, they could be in a position to sell multiple online rights classes or choose to offer “verbatim-use” (simulcast) rights to existing rights-holders as a way of bolstering broadcast-rights packages/ As well, private-network use of broadcast material, including time-shifted copies, should be qualified as a standard fair-use right for users of that network such as a household or a hotel’s employees and guests.

What needs to happen is a common sense of “working out” broadcast rights for live sporting and cultural events so that uses commensurate with broadcasting are protected yet the organiser can sell advanced-interactive use rights to online and mobile providers.

Consumer Electronics Show 2012–Part 1

11/01/2012 Consumer Electronics Show (January - Las Vegas USA) No Comments

This year, the Consumer Electronics Show in Las Vegas has achieved a record of 3100 exhibitors and has made an opening for newer technology companies. This is through the establishment of the “Eureka Park TrendZone” which had space for 94 of these startups.

For Microsoft, this year was their last appearance as an exhibitor and Paul Allen had given the last keynote speech for that company at the CES. They will simply work alongside their hardware and other software partners at further events.

Trends

The major trends have been taking place with the portable and mobile computing aspect of our lives. This is mainly in the form of more powerful smartphones and tablets as well as an increased number of Ultrabooks – small slim ultraportable computers that snap at the heels of the MacBook Air.

Technologies

Energy-efficient powerful processors

This show is being used to premiere NVIDIA’s Tegra 3 ARM processor, which is an improved processor for mobile devices. This is intended to allow for increased power and longer runtime for these devices. This processor isn’t just intended for the tablets but also for use in the car dashboard as has been demonstrated with the latest Tesla electric supercar.

As well, Intel were premiering their Ivy Bridge “classic” processors which are optimised for improved graphics while being energy efficient. These processors are intended for the upcoming generation of laptops including the Ultrabooks.

New operating environments for the regular computer

Microsoft were also demonstrating the Kinect gesture-driven user interface on the PC and this wasn’t just for gaming like its initial XBox 360 application was. They used this show to promote Windows 8 as being the next computer operating system for tablets and regular computers.

Bluetooth Smart and Bluetooth Smart Ready

It was also the year that Bluetoot 4.0 a.k.a. Bluetooth Smart was being promoted. This was a very low-power Bluetooth specification which made the technology work properly with sensor applications due to allowing these devices to run on a pair of AA batteries or a watch battery for many months.

Bluetooth Smart Ready devices could work with these Bluetooth Smart devices and permit them to work in an energy-conserving way. This has legitimised the Bluetooth technology in personal health and wellbeing applications, with this application class being premiered at this show.

Mobile Computing

One technology that is affecting this class of devices is the launch of LTE-based 4G wireless broadband in to most of the USA by many of the US mobile carriers. This is expected to allow for higher data throughput and bandwidth for the data-based services.

Smartphones and Multifunction Internet Devices

One major brand change that occurred over this show was Sony’s handheld-communications identity. This was previously known as Sony Ericsson but is now known simply as Sony Mobile Communications.

Here, Sony had launched the Xperia S Android phone and their first LTE-enabled phone inthe form of the Xperia Ion. These are also to be “PlayStation capable” which allows them to run Sony’s PlayStation games in the manner they are meant to be played. They also released the Walkman Z series which is Sony’s answer to the Apple iPod Touch and the Samsung Galaxy Player multifunction Internet devices.

Samsung had released their Galaxy S Blaze 4G which is their LTE-enabled iteration of their Galaxy S Android phones. LG also released some more of the Spectrum Android smartphones to the US market. Lenovo had launched the first Intel-powered Android smartphone in the form of the K800.

But, for the Windows Phone platform, the big announcement was Nokia’s Lumina 900 which was a Windows Phone equipped with a 4.3” AMOLED touchscreen. Was this a way for Nokia to claw back in to the multifunction smartphone category again?

Tablets

Here, this device class has become more powerful and capable, especially with the spectre of Windows 8 coming around the corner and a strong effort by all to unseat the iPad from its dominant position.

Toshiba had shown a 13” and a 7.7” prototype tablet but were exhibiting their 10.1” Android tablet/ As well, Coby were launching 5 ranges of 7” and 10” Android Ice-Cream-Sandwich-powered tablets with the maximum having 1Gb RAM and 32Gb expandable flash memory.

Acer had launched the Iconia A700 series 10” tablets with Tegra quad-core horsepower, 5Mp rear camera and HD front camera, and driven by Android Ice Cream Sandwich.

Asus had launched the Transformer Prime Mini 7” Android 4.0 comverrtible Android tablet which coudl be similar to the EeePad Memo. This Android Wi-Fi tablet was a 7.1” 3D-screen-equipped unit with 5Mp rear camera / 1.2Mp front camera, stylus and 64Gb flash storage.

Samsung had used this show to premiere the Galaxy Note to the US market and premiere the Galaxy Tab 7.7 LTE which was enabled for the 4G wireless broadband networks.

Sony had launched their S1 Android Homeycomb powered tablet. This one had a 9.4” screen and could work as an electronic picture frame or alarm clock; and was able to work with 4G LTE wireless broadband as well as Wi-Fi. Of course it would work with the DLNA Home Media Network and implemented an “off-centre-of-gravity” position for stability. They also showed the Tablet P clamshell tablet to the US market even though it was available in other markets. They weren’t sure if it would be launched in the carrier-controlled US market.

Regular computers

Ultrabooks and other “traveller” notebooks

This year had been a changing year for the lightweight “traveller” notebook computer. This class of computer had seen the tablet computer appear as a serious competitor and Intel had defined the “Ultrabook” as a new lightweight slimline class of portable hotspot-surfing computer.

ASUS and Lenovo had exhibited convertible Ultrabook computers which could become tablets, with Lenovo’s example known as the Ideapad Yoga which was powered with the Intel Ivy Bridge chipset.

Acer’s next Ultrabook is the Aspire S5. This was claimed to be the thinnest Ultrabook and had an 8 hour battery runtime. It also had a USB 3.0 and Thunderbolt peripheral connect for use with higher-capacity hard disks for example. LG also launched the XNote Z330 Ultrabook as did Toshiba with the Portege Z835 and HP with the 14” Envy Spectre Ultrabook.

Lenovo were exhibiting their IdeaPad U310 (13”) and U410 (14”) Ultrabooks with a choice of processors but with 4Gb RAM and a choice of 64Gb SSD or 500Gb regular hard disk. The 14” U410 variant was also available with 1Gb NVIDIA graphics.

Dell has jumped in to the Ultrabook bandwagon with the XPS 13. This had the standard spec set with an Intel Core i5 Sandy Bridge processor, 4G on the RAM and a choice of 128Gb or 256Gb solid-state storage. The display is typically the 1366×768 resolution with Gorilla Glass screen as well as Bluetooth 3.0. Like the HP Folio 13 Ultrabook, this could be available in a “big-business package” with the business-security and customisation needs or as a regular consumer/small-business package.

Samsung launched their redesigned Series 9 ultrabooks with 13” amd 14” models. These were powered by a Core i5 processor and were equipped with 4Gb RAM and 500Gb hard disk as standard. The 13” variant had a 128Gb SSD as an alternative option.

Of course, the Ultrabook and the tablet had placed doubt on the viability of the 10”-11” netbook. But Lenovo was one of the few who had pushed on with a netbook in the form of the S200 and S206 series. These 11.6” units are available with an AMD or an Intel Atom chipset and  have 2Gb RAM and a choice of 32Gb SSD or 500Gb hard-disk secondary storage.

Laptops

Of course, the regular 15”-17” laptop has not been forgotten about with the calibre of these computers approaching “multimedia” specifications. Most of the 17” units had 1080p resolution and were equipped with Blu-Ray as a standard or option for their optical disks. The hard disks came in the order of 1Tb or, in some cases, 2Tb and system RAM was in the order of 8Gb.

For graphics, most of the laptops on the show floor had NVIDIA graphics chipsets with display memory of 1Gb to 2Gb and able to operate in dual-chipset “overdrive” mode. Samsung even exhibited the Series 7 “Gamer” which was pitched as a thoroughbred clamshell gaming rig.

In-car technology

This year was a chance for new upstarts to integrate the car with the Internet. MOG and Aha by HARMAN have increased their “Web-to-radio” footprint by integrating CBS Radio into their Web content aggregation lineup and partnering with Honda, Subaru, JVC and Kenwood to increase their equipment availability. This is in addition to improving the Aha iOS app and porting this same app to the Android platform this year.

Similarly, Parrot have extended their “Asteroid” Android-driven in-vehicle infotainment platform to three different devices – the Asteroid CK which yields telephony and audio content;, the Asteroid NAV which also provides GPS navigation and Internet access via Wi-Fi; and the Asteroid 2DIN whcih is effectively a car-radio replacement by having integrated AM/FM/RDS tuners.

Stay tuned tomorrow for the next instalment of the Consumer Electronics Show 2012 series which will cover the networked lifestyle at home.

Product Review–Sony CMT-MX750Ni Internet-enabled micro music system

15/09/2011 Network Media Devices, Product Review, UPnP AV / DLNA media-playback hardware) 6 Comments

Introduction

I am reviewing the Sony CMT-MX750Ni Internet-enabled micro music system which is a small-form-factor CD/iPod stereo that can connect to the home network for Internet radio or DLNA-based music playback. It is equipped with a DAB+ digital-radio tuner but there is a version of this system known as the CMT-MX700Ni which doesn’t have this tuner and is available in areas that don’t have Eureka 147 DAB / DAB+  digital-radio services.

From henceforth, I am directing the comments in this review also at the Sony CMT-MX700Ni music system as well as this CMT-MX750Ni, except for any DAB digital-radio comments.

The system itself

Setup and Connection

The CMT-MX750Ni can connect to a network either via Wi-Fi wireless or Ethernet. This allows for flexibility with wired and wireless network setups, such as working with highly-reliable Ethernet and HomePlug networks. You need to use the remote for setting up the music system on a Wi-Fi network that doesn’t use WPS push-button setup. Here, you use the numeric keypad on the remote to enter the WEP or WPA passphrase for your wireless-network segment in an SMS-style manner.

Sony has “reinvented the wheel” when determining how the speakers should be connected to the main unit. Here, they have used a proprietary Molex-style plug at the system end of the speaker cords like they have done with their DVD home theatre systems. Personally, I would prefer that they use a two-conductor 3.5mm phone plug, or the older 2-pin speaker-DIN plug, both of these connections can allow for easier-to-replace, easier-to-modify speaker connection. Infact a lot of the music systems that were sold through the 1970s and 1980s with supplied “separate-piece” speakers, such as the “detachable-speaker” boom-boxes have used either the 3.5mm phone plug, 2-pin speaker-DIN plug or RCA plug to provide “plug-in” speaker connections and these have just worked as well for plug-and-play operation.

The speakers are a typical bass-reflex two-way setup but aren’t aggressively styled. One thing I am pleased about these speakers is that they are well-built and the enclosures use an all-wood construction rather than a plastic front baffle which shows the quality behind the system.

In use

You have the ability to perform basic content-navigation tasks using the controls on the Sony CMT-MX750Ni’s front panel but you need the remote control to use this music system to the fullest. The system uses an “Inverse” LCD display as its display. This yields readable text but Sony could implement a monochrome OLED or fluorescent display rather than the LCD which makes it look “cheap”.

Sony CMT-MX750Ni Internet-enabled music system remote controlOther than that, when you operate the Sony CMT-MX700Ni or CMT-MX750Ni music systems, you find that you are operating a well-built music system. The switches and mechanisms don’t exhibit any sort of tackiness that can be noticed in a lot of bookshelf music systems. The remote control is relatively large and with it you have one-touch access to the sources and main functions as well as being able to do advanced functionality.

The FM tuner didn’t perform properly on the “pigtail” aerial that was supplied with the unit, especially as it was on the lower level of a split-level house. Here, I would recommend connecting it to a better FM aerial like an outside one if you want the radio to work properly in a difficult scenario.

This setup didn’t challenge the DAB tuner with it able to survey the DAB+ multiplexes in Melbourne and provide clear and reliable reception from any program on these multiplexes.

The CMT-750Ni and CMT-700Ni use an iPod dock that drops down from the front panel. This makes it easier to hide the dock if you are not using an iPod or iPhone with it. As well, the iPod or iPhone can lean against the front panel while plugged in without the need to use any dock adaptors. The only limitation with this is that you need to pull back a hard-to-discover latch before you can close the iPod dock.

The front-panel USB socket allows you to play music of a USB memory key, SD card adaptor or smart phone. But it is “live for power” only when system is in operation and supplies the power when you select other sources so you can charge up your Android smartphone or other USB-connected device. This situation is similarly true for the system’s iPhone dock and it could be tempting for users to dock their iPhone in this CMT-MX750Ni’s dock in order to charge even if the system is not playing. It could have the option to supply power to charge devices connected to the USB socket or iPhone dock even when the Sony music system is in standby.

When the Sony CMT-MX750Ni or CMT-MX700Ni plays Internet radio and loses the connection to the station, it doesn’t try to reconnect to the station unlike the other Internet radio products I have used. Here, it just goes back to the main menu and you have to retune to that station, and this can be annoying with over-subscribed Internet streams. Other than, the Internet radio experience works properly as best as the link can allow.

This system works as an audio device in the DLNA Home Media Network. This includes the ability to play audio content that is “pushed” to it from a DLNA-compliant control point like Windows Media Player or TwonkyMedia Controller. It serves this function properly whether you pull the content up using the unit’s control surface or push the content out using a DLNA control point.

These music systems can work in the “Party Streaming” mode where multiple Sony receivers or music systems connected to the same home network can stream the same content at the same time. The CMT-MX700Ni or CMT-MX750Ni systems can work as either a host or a client system in this aspect.

Sound Quality

There is the ability with these Sony music systems to adjust the tone of the sound system. This can only be done using the remote control and you have to press the EQ button on that controller. Here you have access to bass and treble adjustments but you can also enable a “Dynamic Sound Generator” mode using a separate button. This may add “extra bite” to some recordings but may not yield difference with other recordings and may be about providing “big speaker” sound out of small speakers.

The sound quality is typical for a high-end “micro” form-factor music system but can clip or sound “muddled” around just near the maximum volume point. I have observed this with recent popular RnB music which is tuned for a loud sound with excessive bass but It can “go loud” on recordings that weren’t tuned “loud”, although I have had the CMT-MX750Ni run at “flat” tone settings.

I even ran this system on a DAB+ broadcast of an ABC Radio National program and had noticed that the speech from the show’s presenters came through very clear, crisp and intelligible. This didn’t matter whether it was a man or woman speaking in the show.

Limitation and Points Of Improvement

The “pigtail” aerials (antennas) supplied for DAB and FM use are inadequate for reliable FM or original-specification DAB digital radio (UK, Denmark, etc). As well, these supplied antennas remind you of using the typical clock radio which has this kind of FM aerial and are out of character with this system’s class. It could do better with a “whip-style” aerial similar to what is used for the Wi-Fi network connectivity and could support “single-input” aerial setups through an option.

Other connectivity improvement that It could also benefit from include having a pair of RCA line-input connectors or a “tape-loop” set of input and output RCA connectors on the back of the system for whenever you connect a computer, tape deck or other piece of audio-equipment in a semi-permanent manner. It can also benefit from a headphone jack for private listening purposes. Similarly, it could also benefit from integrated Bluetooth A2DP functionality so it can work with phones and media players that use this medium as a way of transmitting music data.

Sony CMT-MX750Ni Internet-enabled music system iPod dock

iPod dock with fiddly latch that needs to be released to close it

I would also improve the iPod dock so that you don’t have to operate any latches to open or close the dock. As well, I would provide the ability to charge smartphones connected to the USB socket or docked in the iPhone dock while on standby as a user-selected option. This can allow the user to keep an iPhone or other smartphone “topped off” when docked or connected to the system.

Another point of improvement would be to allow the CMT-MX750Ni music system to retry Internet-radio streams if the stream it is tuned to “gives up the ghost”.

I would also like to see the Internet-media and home-network-media functionality implemented into most of Sony’s bookshelf-stereo range and / or for Sony to develop a network-connected CD receiver along the same lines as the Rotel RCX-1500 CD receiver I previously reviewed.

Conclusion

I would recommend purchasing the Sony CMT-MX750Ni or CMT-MX-700Ni network-enabled music systems for use in a small room like a bedroom, den or office. It may work well for use in an apartment’s small living area.

On the other hand, I wouldn’t use this music system in situations where it is expected to fill a large room with music or play in a noisy area like a party or cafe.

UK riots–Best Internet resources to follow with

09/08/2011 Current events No Comments

I have been following the UK riots very lately and have found that the BBC do provide good quality resources which can be of benefit around the world.

This would be important if you have relatives or friends who are based in the UK. Also, some of you may not have adequate coverage of this event in your country, especially on TV.

BBC Radio London (available on all Internet-radio directories – vTuner, Reciva, RadioTime)

There is continual reporting from the front with news and traffic reports being run on the quarter-hour. The traffic reports do yield information about areas that have been closed off and give a sense of where the troublespots are by reporting on road and rail closures.

BBC microsite

This site is running as a live dashboard but the live TV feed from BBC News 24 may not come through due to it being oversubscribed. There is a BBC ticker with news and information from different sources, including Twitter and email.

Other resources

The Guardian also run a microsite which is regularly updated with news as it comes in.

There is also a Google-powered map which has the verified areas where the trouble is occurring and this is based on verified data. This may be useful if you want to check whether your loved ones are at threat from the riots.

The unit's remote control

It is a small device about the size of two packets of cigarettes stacked on top of each other and is powered using a power adaptor. Users operate it with a very small remote control that has the main transport functions and a D-pad for navigating around the user interface.

Setup

How this connects to your TV

The device connects to the TV using an AV cable that plugs in to a four-conductor 3.5mm jack on the back of the unit. There is another 3.5mm four-conductor jack for connecting to the component-video connections on a suitably-equipped display device with a separate patch cable. Of course, this unit can be connected to HDMI-equipped display devices like most plasma and LCD TVs; and it has an optical SPDIF socket for connection to equipment with an optical digital input like most surround receivers.

Sadly, this device doesn’t support connection to display devices that use RGB inputs in any form. This may affect those of us who want the best out of monitors or projectors that use such connectors like most SCART-equipped European TVs, business-focused “data projectors”, classic “3-gun” projectors or professional-grade video displays. You may get around this by connecting the device to the display via one of the “HDFury” HDMI-RGB adaptors

It has the ability to play media that is held on USB-attached storage devices like memory keys or USB hard drives. This can be useful for playing media that you have held on one of these devices.

As for video codecs and file types, it can natively handle most audio and video file types including the DivX and Matroska MKV family of file and codec types.

Network setup

The WDTV Live HD can be connected directly to an Ethernet network or HomePlug AV network with the appropriate “homeplug” bridge device, But it is one of these “wireless-ready” devices that connects to a Wi-Fi network using an optional Wi-Fi dongle available from Western Digital or through one of their retailers.

Use

This can work with any display device including older TVs

The user interface is a “full-screen” one which works to the edge of the screen. This may be of concern with those of us who have hooked the WDTV Live up to an older CRT-based TV set that has the orthodox curved screen edges. As well, the logos for the Internet services are rendered in a dull manner and could benefit from “true-colour” display with a highlight around the currently-selected service.

Of course, there is a screen-saver function which can be overridden for displays that aren’t affected by long-time display of images or set to appear after a time between 5 minutes to 15 minutes. Here, it just shows the WD logo; but could show now-playing information during audio playback.

Online services

The Facebook service has the expected functions like viewing one’s own news feed, contributing to a Status Update or writing one’s Status Update as well as the ability to view one’s Photo Albums or a Friend’s Photo Albums. All text entry is based on “pick-n-choose” methods and the pictures do come up properly on the full screen.

I have tested the YouTube service with this device and have used it to play some videos including the service’s “poster child” video which is the “Keyboard Cat” video. The user interface is what would be expected for a 10’ interface and the users would be required to use the “pick-n-choose” method for any text entry like account login or video searching.

The “Tune In” Internet-radio function works properly for Internet radio access and allows the Internet radio stream to play in the background while you navigate the menus. During the day, It had performed well on quality-of-service when streaming Internet radio; but like all Internet services, this will depend on how congested the connection is.

UPnP AV / DLNA media access

The UPnP AV / DLNA functionality on the WDTV Live works properly when you use the remote control to call up the content on your UPnP AV / DLNA Media Server. In previous firmwares, this media player had problems when playing out media under the control of a UPnP AV Control Point like Windows 7 or TwonkyManager. Here, it would play only one item at a time and require the user to advance the media to the next item using the remote control or the Control Point.

Now, units that have firmware newer than version 1.65 can play multi-item playlists and slideshows without needing to be “pushed on”. There is still a problem with this function, especially with image slideshows and video playlists where the unit will show its menu every time a new image or video is loaded up before it plays that image. This could be improved with “read-ahead” buffering for subsequent media items.

Limitations and Points Of Improvement

I would like to see the user-interface improved in various ways, such as use of brighter colours or full-colour logos for the Internet services.  The screen-saver could also support “service-driven” behaviour like showing now-playing information for audio sources.

As well, this device could benefit from integration with local online-video services like the local “catch-up TV / video-on-demand” services offered by the local TV stations. Of course, I would like to see an improvement on the media changeover behaviour when the device is used as a UPnP AV / DLNA MediaRenderer under the control of an external control point.

This device’s form factor could be taken further with an integrated digital-TV tuner for implementation as a digital-TV set-top box that could have online and network media access as well as digital-TV access.

Conclusion

I would recommend the Western Digital WDTV Live or any of its successor models as a cost-effective device that can be useful for pressing a cheap or old TV, monitor or projector in to service as a network media playback device in the UPnP AV / DLNA Home Media Network.

Product Review–Pure One Flow portable Internet radio (Frontier Internet Radio platform)

17/02/2011 IP-based broadcasting, Product Review, UPnP AV / DLNA media-playback hardware) No Comments

Introduction

I am reviewing the Pure One Flow portable Internet radio which is the younger brother of the Pure Evoke Flow radio that I have reviewed a while ago. This unit is designed along the same lines as the “old-style” portable radio that can be perched on a window sill or the top of a fridge.

The Internet radio

The Pure One Flow is the same size as a midsized portable radio and is housed in a rubberised cabinet with knobs for volume and “select” function and buttons below LCD display. The rubberised casing is a marked difference from the glossy plastic that is used on some radios, which attracts fingerprints and is hard to keep clean. I also like the knobs, especially for the sound volume because it is an interface most of us are accustomed to, where you can just “flick” the knob downwards to turn it down.

Like the Evoke Flow radio that I previously reviewed, this unit can work on AC using a supplied “wall-wart” power adaptor or battery power using a “ChargePAK” rechargeable battery pack that is available as an extra-cost option.

Pure One Flow portable Internet radio - side viewAudio connectivity is in the form of an auxiliary-in jack so you can use the radio as an amplified speaker for your MP3 player or other audio device. It also has a headphone jack which is a connection that I am noticing is becoming increasingly rare for Internet radios. The reason I find this connection important is that you could use an active-speaker system like a pair of computer speakers as better-sounding more-powerful speakers for the radio.

The set works well as a DAB-based digital radio, being able to pick up all of the multiplexes that are broadcast in our area.

For Internet-radio station selection, this unit uses a  “Form style” user interface if you intend to select a smaller group of stations but will give you the complete list of stations if you are just browsing. This is in contrast to the “tree-based” approach that most Internet radios use for selecting stations.

There is also access to a “sounds” service where you can hear sounds like sea wave; as well as access to the “FlowSongs” music download service.

This radio works properly as a DLNA-compliant media player, being able to play most audio file types that are held on UPnP AV media servers.

The sound quality for this set is very similar to an average mid-sized portable radio such as the archetypal transistor radio of the 1960s. It can still fill an average-sized room with music and the sound is focused around the middle frequencies.

Limitations and Points of Improvement

This unit could be improved with the telescopic aerial being used for the Wi-Fi wireless network as well as for FM and DAB radio.  The Wi-Fi functionality could work well with keeping the details for up to five wireless networks, which can be useful if you take the radio between multiple locations, which is something you would be tempted to do more readily with this set.

Another limitation is that you can’t enable daylight-saving time on this set. Instead, when you determine the time zone, you only can set up for standard time. This could be rectified with a firmware update which exposes a “daylight-saving” on-off function or access to a table of “spring-forward / fall-back” times hosted on the manufacturer’s Website.

Another improvement that I would like to see would be to support regular AA, C or D batteries even with a battery cage so you don’t have to look for the hard-to-get ChargePAK battery packs.

Conclusion

This set may be considered as an option when you want to replace that old “transistor radio” with something that gives you access to “modern” radio sources like DAB or Internet radio. It could he very useful where you want a set of this class to be highly rugged and durable.

Product Review–Pioneer NAC-3 Internet audio system with 2 iPod Docks

29/01/2011 Product Review, UPnP AV / DLNA media-playback hardware) No Comments

Introduction

I am reviewing the Pioneer NAC-3 (XW-NAC3) Internet music system with 2 iPod docks. This DLNA-enabled network media unit is a flagship model that heads a series of iPod speaker docks that Pioneer has recently released and is the latest attempt by this company to sell “small-set” audio equipment like portable, clock and table radios.

This Japanese company has always been known for high-quality home audio / video equipment since the 1960s and car audio equipment since the 1970s but has dabbled in the highly-competitive product class at various times through the 70s and 80s, initially selling these goods under the “Centrex” brand in some markets but eventually simply selling them under their own brand. This unit is an example of how Pioneer, along with the other Japanese consumer-electronics companies are trying to get their claws back in to a very competitive product class which is awash with many cheap Chinese-built products that are sold under many different brand names.

As an echo to the earlier attempts in the “small-set” audio product class, this unit has functionality that makes it stand out from the pack. One party piece is to work with 2 iPod or iPhone devices and play tracks from one or both of the devices and another one is to properly implement “three-box” DLNA Network Media functionality where it can be managed by a Windows 7 computer or other DLNA control point.

It will also be the first time I have reviewed a network media device and am implementing these “at-a-glance” tables for this class of device. Regular readers may have noticed that I am implementing these “at a glance” tables when I review laptop computers and printers so people can see the basic facts about these products before they read the review text.

The unit itself

Pioneer XW-NAC3 remote control

Card-type remote control

This unit has been designed to appeal to the young generation who just want something new rather than your “father’s old station-wagon”. Here, it has a shape that is similar to a banana and is finished in a glossy-white plastic cabinet. It can come with three different speaker-cloth colours – burgundy-red, black or white. As well, it comes with a card-size infrared remote control which you have to use for operating most functions including access to Internet radio.

This unit can play music from 2 iPod or iPhone devices; a Bluetooth A2DP-compliant audio source, a USB Mass-Storage Device or a line-level source as well as material over the network. But this set lacks some functions that I have been used to with most Internet radio units that I have reviewed previously on this site.

One function that it misses is the ability to connect to the host network via Wi-Fi wireless. Here, you have to connect it to the network using an Ethernet cable, but you could use a HomePlug kit or a Wi-Fi-Ethernet client bridge to connect it to the home network and want “around-the-home” flexibility without needing to lay Ethernet wiring. The other function that it lacks is access to regular broadcast radio, whether FM or DAB+ digital radio. This may not be of concern if you are seeing this unit as an Internet-enabled complementary radio / network music terminal / iPod speaker doc while you use your ordinary radio (which most households have plenty of) for listening to regular local broadcast radio.

iPod playback

2 iPod docks on the Pioneer NAC-3

You can play and charge two iPods or iPhones here

The ability to play and charge 2 iPod or iPhone devices is useful for quite a few applications. For example, a person who has one of those high-capacity “iPod Classic” series devices can still use this device as a “jukebox” alongside their new iPhone 4 that they have just signed a contract for. This is infact the demonstration setup that I used with an iPod Classic and an iPhone that I had borrowed from a teenage boy that is living with me.  Similarly, a household with many “iDevices” can this as a charging station for two of these devices. The two-iPod function is augmented by a dual-device shuffle mode which plays tracks from each of these devices sequentially. The iDevices can even be put in to “shuffle” mode so as to allow the unit to randomly pick music across the devices.

Bluetooth A2DP

The system can also work with Bluetooth A2DP audio sources like a lot of mobile phones, tablet computer (including the iPad) or some MP3 players. Here, this worked as a “Bluetooth speaker” for my Nokia N85 mobile phone and had worked as expected. The track navigation and PLAY/PAUSE buttons on the remote control had controlled the music playback on my phone.

The pairing experience was a bit confusing because there was one procedure to set up the paring code but this didn’t make the unit “open for pairing”. You actually had to press the PLAY button on the remote control to achieve this goal and begin the pairing process.

Network functionality

All the media available via the home network connection is accessed when you select “Home Media Gallery” as the function source. This includes the Internet radio as well as music files available from any of the DLNA Home Media servers on your network.

Internet radio

The Internet radio works from the vTuner Internet-radio directory and has the similar directory structure to all of the other radios that I have reviewed. It has the ability to store 30 Internet-radio stations with 10 stations in three “classes”. You will have to use this function once you regularly listen to particular Internet-radio stations because if the set loses connection with the station, you will need to “retune” to that station.

It can handle jitter and latency situations OK but as I have said before, it goes to the “Home Media Gallery” menu once it drops out and loses the connection. This can happen at busy times when the Internet service is oversubscribed and there isn’t proper QoS functionality on the network between the radio station’s server and this set.

DLNA network media

This unit integrates properly with the DLNA Home Media Network. Here, it will work as a network music player where you select your content using the NAC-3’s display and remote control; and it will even list the UPnP AV / DLNA Media Servers that exist on your network when you select the “Home Media Gallery” function so you can start “delving” in to the content on your desired server.

It also works properly as a network-controlled music player when you use a UPnP AV / DLNA control point program like Windows Media Player 12 (Windows 7) or a mobile phone with a DLNA media control program. I have even tried this with my Nokia N85 phone which I use as a personal “Walkman” and have “pushed” music held on the phone to this unit via the home network. As well, unlike some DLNA-compliant media players that are meant to work under network control that I have used, this unit will even play a program of music that you direct it to play from the network-based control device.

Sound Adjustments and Quality

There are bass and treble controls accessible from the remote control but I had kept the bass and treble set at “flat” so as to hear a sound that I can assess fairly. There is a “sound-effect” button which allows the system to be switched between a “vivid” mode with a bit of extra bass and treble, a “Lo-Fi” mode which yields a cheap transistor-radio sound and an “ALC” mode which keeps the sound level constant for use in noisy environments.

Even if I don’t use the sound-effect modes and I have the bass and treble flat, this Internet radio doesn’t sound like a “gutless wonder”. There is still some punchy bass even with popular music that was recorded before there was the desire to make such music sound boomier and louder. Yet you still hear the vocals and instruments that carry the body of the music clearly and distinctly. Even the heavy bass lines from the recent dance tracks that were on the iPod and iPhone that I borrowed from the teenager to try out the dual-iPod functionality didn’t worry this music system much and they still sounded “tight” – there wasn’t that old bass-heavy “jukebox” sound.

Limitations and Points of Improvement

The Pioneer NAC-3 Internet music system could benefit from integrated Wi-Fi wireless-network or HomePlug powerline network connectivity. This is more so because it is the kind of network device that appeals to being taken around the house from room to room.

It could also benefit from a headphone jack because some people use this jack to connect a more-powerful active-speaker system or an amplifier to these devices for increased sound output. As well, the VIDEO output on this unit could be used not just for iPods and iPhones that have a video output. Here, this jack could work with the DLNA network media player to play pictures and video material through a connected TV set.

The Internet radio functionality could have some improvements in the way it operates. It could come back to the “last-tuned” Internet station or attempt to reconnect itself after a dropout. But this may have to be facilitated through a separate “Internet Radio” function on the function selector like what most other Internet radios have.

Conclusion

I would recommend this unit for people who either run two or more iPods or iPhones; a Bluetooth-enabled music-capable phone or have established a DLNA Home Media Network and want a “complementary” transportable device that can get the most out of their digital music library available on their portable devices or home network.
