Introduction

Between the end of October and the beginning of November, I had a chance to interview people who work with two different companies that work in the consumer audio-video market and had noticed some trends concerning this market and its relevance to the online world.

One main trend was that there was increased focus by consumer-audio manufacturers who work in the popular marketplace on delivering DAB+ digital radio equipment rather than network-connected audio equipment to the Australian market. This may be because some of these firms need to see this technology become more popular here and want to have “every base covered”.

Sony

From my interview with Kate Winney I had observed that Sony had a strong presence in the connected-TV scene. Here, this was more concentrated with their newer “main-lounge-area” TVs but they are providing this functionality on some of their video peripherals, namely their BD-Live Blu-Ray players.

We agreed that Sony had no Internet radio in its product lineup although they implement Shoutcast on their high-end home-theatre receivers like the STR-DA5500ES. But we agreed that they need to make DAB+ available on their stationary “big sets” like hi-fi tuners, receivers, home-theatre-in-box systems and bookshelf audio systems. They are releasing a few DAB+ sets but most likely as stereo systems rather than as portables or components.

I had stressed to Kate about Sony implementing vTuner or a similar directory-driven service which is implemented in most Internet radios. This is because most of these services offer access to the simulcast streams of the government, commercial and community radio stations broadcasting to local countries around the world as well as the Internet-only streams of the kind that Shoutcast offers. It is also because most people who are interested in Internet radio are likely to want to use it as a way of enjoying the “local flavour” of another country that is provided by that country’s regular broadcasters rather than just looking for offbeat content.

Kate also reckoned that DAB+ digital radio needs to be available in the dashboard of cars in the new fleet, preferably as standard equipment or as a “deal-broker” option offered by car dealers for the technology to become popular. I was also thinking about whether Sony should offer DAB+ technology as part of the XPLOD aftermarket car-audio lineup.

Bush Australia

From my interview with Jacqueline Hickman, I had noticed that Bush are still focused on implementing DAB+ digital radio in Australia but are using Internet radio as a product differentiator for their high-end “new-look” sets that are to appeal to young users

Their market focus for consumer audio is on the “small sets” like table / clock radios, portable radios, small-form stereo systems but I have suggested implementing or trying some value-priced “big sets” as product ideas. This is even though they run some “main-lounge-area” TVs and digital-TV set-top boxes in their consumer video lineup.

The ideas I put forward are a DAB+ or DAB+ / Internet-radio tuner that is for use with existing audio equipment and a FM / DAB+ (or FM / DAB+ / Internet-radio) CD receiver with optional speakers. A market that I cited are the mature-aged people who own “classic hi-fi speakers” from 1960s-1980s that they like the look and sound of but may want to run them with a simpler cost-effective component. I had made a reference to the “casseivers” of the late 70s and early 80s which have an receiver and cassette deck in one housing and what these units offered. Jacqui had reckoned that companies like B&O and Bose filled the market but I have said that some of the companies have gone to active speakers rather than integrating power amplifiers in the equipment. As far as the DAB+ tuner is concerned, she suggested that a person could use a portable DAB+ set and connect it to the amplifier using an appropriate cable.

I raised the topic of IPTV but Jackie was not sure whether this will be implemented in any of their TV sets or set-top boxes at the moment. This sounds like a product class that hasn’t been properly defined with a particular standard and platform especially in this market.

Conclusion

It therefore seems to me that there is more interest by consumer-electronics companies in nurturing the DAB+ digital radio system and the DVB-T digital TV system because they are based on established technology and established metaphors; and appeal more to “Joe Six-Pack” than the Internet-based technologies.

Also, I had noticed that it takes a long time for all equipment classes to benefit from a new technology. This is more so with DAB+ digital radio and, to some extent, Internet radio where the mains-operated stationary “large sets” like hi-fi equipment and stereo systems are under-represented.

Facebook started it. Windows Live Photo Gallery has implemented it since the 2010 version and made it easier with the 2011 version.

What is people-tagging

The feature I am talking about here is the ability to attach a metadata tag that identifies a particular person that appear in a digital image. These implementations typically have the tag applied to a specific area of the photo, usually defining the face or head of the person concerned. It will also become available in current or up-and-coming versions of other image-management programs, photo-sharing services, DLNA media servers and the like.

In the case of DLNA media servers, one of these programs could scan an image library and make a UPnP AV content-directory “tree” based on the people featured in one’s photo library.

Initially the concept, especially the Facebook implementation, was treated with fear and scorn because of privacy invasion. This is because this implementation allows the metadata to be related to particular Facebook Friends and also allows the photo to be commented on by other Facebook Friends. Now the Windows Live Photo Gallery application attaches this metadata in a standardised XML form to the JPEG file like it does with the description tags and geotags. There is the ability to make a copy of this file without the metadata for use in posting to Internet services.

A relevant implementation idea

One key benefit that I would see with this data when implemented with electronic picture frames, HDTVs and similar devices is the ability to overlay the tags over the picture when it is shown. This could be achieved by the user pressing a “display” or similar button on the device or its remote control. Devices with touchscreens, stylus-operated tablet screens or other pointer-driven “absolute” navigation setups could support a function that shows a “people tag” as you touch areas of the image.

Benefit to Alzheimers sufferers

Here, this feature could help people who suffer from Alzheimer’s or other dementia-related illnesses by helping them remember whom their family members or friends are. If the user is using an image-management program or DLNA media-server setup capable of using these tags, they can call up a collection of images of the person they think of and have those images appearing on the screen. If the device has a communications-terminal function like a telephone, one of the images can be used as an index image to remember the correspondent by. This function could be extended by the use of an automatically-updated index image or a screenshow that shows “key” images of the person.

Improving on the idea

To make this work, there needs to be an industry standard that defines how the people-tag metadata is stored on the JPEG file. As well, the standard has to support functions like one or more separate “nickname” fields for each of the people that can be displayed as an option.  This is because a person may be known to one or more other people via a nickname or relative-shortcut name (Mummy, Daddy, Nonna, etc).

Another issue is to encourage users to establish consistency whenever they tag up a collection of images. This could be achieved through “batch-tagging” and / or improved facial recognition in image-management tools. This may be an issue if two or more people are tagging images from their own collections to serve a third collection and they know the people via different names.

Conclusion

Once we cut through the hysteria surrounding people-tagging with digital images and focus on using it as part of desktop image-management systems rather than social networks, we can then see it as a tool for helping people remember whom their loved ones are.

Previously, I have mentioned in this site about PlugPlayer which is a DLNA Media Controller app for the iPhone and iPod Touch. I have cited it more as a solution to bridge this popular smartphone with the DLNA Home Media Network.

Now this app has been ported to the iPad and is able to take advantage of the larger screen area offered by this new device. It is mostly based on the iPhone version but there are plans to make this app use all the assets of the iPad as it is revised.

This may appeal to those of you who want to see the iPad work as a coffee-table control point for the DLNA Home Media Network or bring up pictures and videos held on a network-attached storage on the iPad.

As well, any of you who own a Linn DS network-audio streamer that works with Cara software can be sure that the latest version of this software will offer the full functionality of the latest firmware. This includes on/standby, access to Internet radio as well as source selection.

From the horse’s mouth

Vodafone Mobile Wi-Fi R201 – Product page

My comments on this device

I have come across most of the small wireless-broadhand Wi-Fi routers and most of them seem to offer the same functionality – working just as a wireless router for wireless-broadband services. But the Vodafone Mobile Wi-Fi R201 has offered more than the typical device of its class.

This battery-operated device has a built-in microSD card and is able to work as a network-attached storage device as well as a router for wireless broadband. It can present the files via three different protocols – SMB/CIFS, HTTP or UPnP AV / DLNA for media files. The latter function is provided for by TwonkyMedia Server which is being integrated in to many network-attached storage devices.

It can be powered from AC power, USB or integrated rechargeable batteries but, due to its small size, it doesn’t have an Ethernet connector for either LAN or WAN (broadband) connectivity. An Ethernet connector being added to the device could allow the unit to become a NAS / wireless access point for an existing network or it could work with a cable or ADSL modem as a router. As well, it is dependent on the Wi-Fi network as the primary connection method.

The unit can work tightly with Windows 7 or with other operating systems and devices that support WPS, especially the PBC “push-to-connect” method. As well, the PSK passphrase for the WPA2 security setup and the SSID are unique to each unit, which makes for better security.

Another feature is that this particular “Mi-Fi” can work alongside the network-connected computers as an SMS send/receive terminal. This is done using a Web form that is part of the Web management interface for this device.

My comments about this device is that it would work hand in glove with a portable Internet radio like the Pure Evoke Flow that I previously reviewed as long as you have a generous data plan on the SIM card for receiving Internet-radio programs. This is intensified by you putting a microSD card full of music or a SlotMusic card (the microSD equivalent of the pre-recorded Musicassette) in this device and using the radio’s DLNA music-player mode to play the music files from the card.

As well, I would recommend that users who buy this device buy a USB car charger that plugs in to the vehicle’s cigar lighter in order to avoid compromising the device’s battery life when they use it in the car. This charger should have a standard USB socket on itself or a microUSB plug that fits the device.

By the way, it is worth noting that this router is now available in the UK and will be rolled out to countries that Vodafone does business in as a name.

 NETGEAR Rolls Out HD Media Players, UTM and Powerline Products – SmallNetBuilder

My Comments

I have read the attached article and found that most of the devices had impressed me as devices that would work well in a home or small-business network. This was because of particular abilities that had made the devices unique rather than run-off-the-mill devices.

NeoTV network media players

NeoTV 550 network media player

This group of NeoTV network media players may be very similar to the other network media players  like WDTV Live that are appearing on the market. This is that they are capable of playing audiovisual media held on a USB memory key, camera card reader or external hard drive; or from a DLNA/UPnP-AV-compliant media server that exists on your network. But one of the models in this lineup, the NeoTV 550,  has eSATA connectivity and the ability to be a Blu-Ray Disc player when connected to an optional eSATA-connected Blu-Ray drive. This can benefit people who want to consider running this unit alongside their DVD player as a network media player but may take the plunge for Blu-Ray when they are ready.

At the moment, I am not sure whether this unit can work as a substitute DVD player if it is connected to an eSATA or USB DVD drive or a DVD is loaded in to a connected Blu-Ray drive.

HomePlug AV 802.11n access point

XAVN2001 HomePlug AV 802.11n wireless access point

One device I am pleased to see on the scene is the XAVN2001 HomePlug AV 802.11n wireless access point which work like some of the 802.11g wireless access points that can connect to a HomePlug 1.0 Turbo segment. It is also available as part of the XAVNB2001 kit which includes the Netgear XAV2001 HomePlug AV-Ethernet bridge as well as this access point. Like these other access points, this unit plugs in to the wall and works as a bridge between an Ethernet segment and a HomePlug AV powerline segment as well as being an access point for a 2.4GHz 802.11n wireless network.

This device can work as a way of extending the effective radio footprint of an 802.11n wireless network with the use of an Ethernet or HomePlug AV wired backbone. On the other hand, it could bring an 802.11n wireless network and Ethernet network point in to an outbuilding or static caravan (trailer) in the manner talked about in my feature article “Multi-Building Home Networks”.

Quick extension-access-point setup with WPS

I had done further research about this access point through Netgear’s Web site and found that this unit uses WPS as a way of simplifying the creation of a multiple-access-point wireless-network segment. This kind of segment, also known as an “extended service set” makes use of multiple access points with the same SSID, network operating mode and security parameters so a portable device can move between access points with minimal user intervention. I have written a bit about the concept of using WPS as a way of simplifying setup of a small multi-access-point wireless network in an article I had posted last year on this site at its old location and had moved to the current location.

The user just has to hold down the unit’s ON-OFF button for a few seconds then press the WPS button on the WPS-ready wireless “edge” router to start the configuration routine. A few moments later, they are then able to move the access point to the area where the Wi-Fi network is needed and proceed to connect this access point to the Ethernet or HomePlug AV backbone which the wireless router should be connected to.

Conclusion

If more manufacturers can look towards making affordable and easy-to-use network devices, they can end up with equipment that will appeal to most users and have equipment that is out of the ordinary.

HTC Unveils a DLNA-based ‘Media Link’ for Handset TV Streaming | eHomeUpgrade

My comments

At the moment, Samsung has already delivered a DLNA media control point / server with their Android handsets in the form of AllShare. This would have meant that someone who had an HTC Desire or wanted to start a mobile service contract using an HTC Android handset would have had to visit Android Marketplace to add on TwonkyMedia Server and Andromote to add on DLNA media-sharing / media-control functionality to their handset.

But HTC is intending to supply a “Media Link” app with their newer Android handsets to integrate them in to the DLNA Home Media Network. At the moment, this app is standard with the upcoming Desire Z and HD handsets and is intended to be available for newer HTC Android handsets.

The main issue I have with this app is whether it is available as an in-place upgrade or add-on for existing HTC Android handsets or will these users need to look towards Andromote and TwonkyMedia Server?

From what I have gleaned about this program, it seems to be able to work with content held on the handset but I would like to know whether a person can use the handset to have content held on another DLNA media server like a NAS playing on the DLNA-enabled media player or be able to “pull-down” selected content held on the DLNA media server to the phone via the network.

It is still worth keeping an eye on the Android market for apps that may do the job better than whatever comes with the phone, especially if you are after more DLNA functionality.

I have been observing various Web feeds and found that Samsung has been working heavily on contributing to the DLNA Home Media Network in many different ways.

They had integrated the functionality in to most of their high-end Wi-Fi-enabled digital cameras and into their smartphones issued over the last year or so. An example of this is Epic 4G which is the latest 4G-enabled smartphone now available to Sprint customers in the US, where this phone can be a media player, server and controller.

As far as the main lounge-room or home theatre is concerned, all of their TV sets that are based on the Series 7, 8 or 9 chassis which includes most, if not all, of their “main viewing area” flatscreen TV models sold over the last two years are DLNA enabled and is now integrated into an increasing number of the Series 6 flatscreen TVs issued since model-year 2009. These TV sets and the DLNA-equipped ones offered by Sony have been considered as an option for small business and education when it comes to applications like digital-signage because of their cost-effectiveness and ready availability at most of the big-name electrical retailers.

As well, they are rolling this function in to most of their Blu-Ray players and Blu-Ray-based “home-theatre-in-box” systems. Surprisingly, they have provided this function in to the BD-C8000 which is the Blu-Ray equivalent of the portable DVD player that may be used to “pacify” kids with a movie during a long road trip. This is a product class that is less likely to be endowed with this kind of functionality because most of these players are made in a cost-driven manner.

It will be interesting to see what Samsung will come up with next as they design and release newer equipment over the subsequent years.
