My Comments

The vinyl revival is upon us whether you are a young person who didn’t grow up with playing records or an older person who habitually played records on that stereogram or hi-fi system and maintained that record collection. But a significant number of turntable manufacturers have moved away from the purely-analogue “back-to-basics” approach to the classic LP record by bridging digital technologies with that classic music medium.

In a lot of cases, turntable manufacturers have issued at least one turntable model in their range that uses Bluetooth to stream audio from that record to Bluetooth speakers or headphones. Yamaha recently issued the MusicCast VinylPlay 500 turntable that streams the record you are playing through your home network to their MusicCast speakers and amplifiers or plays online sources using a MusicCast app.

But Pro-Ject have come forward with a network turntable that uses UPnP / DLNA to stream the music off that record you have put on to a wide range of network audio equipment using your home network.

Pro-Ject have had a significant hand with the vinyl revival. This is with designing and releasing a value-for-money manual turntable that answers the expectations of “born-again” vinyl enthusiasts and participating in the Australian edition of Record Store Day which celebrates independent “bricks-and-mortar” record stores.

The Pro-Ject T2W Wi-Fi turntable is a belt-drive manual-operation turntable that works with 33rpm and 45rpm records. Records are placed on a glass platter rather than a plastic or lightweight-metal platter, which does a better job of absorbing unwanted vibrations. The tonearm is equipped with a Sumiko Rainier moving-magnet cartridge most likely

But this turntable streams the music content over your Ethernet or Wi-Fi home network to any UPnP / DLNA network audio endpoints with it supporting a best-case FLAC lossless audio stream. The Wi-Fi wireless network connection works best case to Wi-Fi 6.

You have to use the Pro- Ject Control App on your smartphone or tablet to set the T2W up for your home network. But this also works as a UPnP / DLNA Media Controller, allowing you to “push” the music stream from your currently-playing LP to a DLNA audio endpoint. The turntable also has a button to “push” the music stream to the last-connected DLNA endpoint so you don’t have to get out your smartphone to do this before you lift the arm on to that album. The Pro-Ject Control App also can allow you to use Sonos or Apple AirPlay 2 compatible equipment to hear that album.

Between the moving-magnet phono cartridge and the Wi-Fi streaming subsystem exists a high-quality analogue split-passive phono preamp which also yields the sound from that album to a line-level input on an amplifier. This would come in handy with music systems that don’t have a phono input that you would typically connect a turntable to. I have done further research and there doesn’t seem to be the ability to run the audio signal to an external phono preamp such as the one built in to that 70s-era hi-fi receiver.

Pro-Ject recommends that you use the control app associated with a UPnP / DLNA capable network multiroom setup to discover the turntable and push its output across the speakers in that setup. This is to assure proper synchronous sound output because one device would be used to “collect” the signal and synchronise it across the different member endpoints in that setup. Pro-Ject doesn’t assure that the T2W’s UPnP setup will lead to proper sync across different devices due to differing buffering capabilities.

This may appeal to people who have an Internet-capable audio system that uses UPnP / DLNA and want to play records through that system via the home network without it being necessarily close to the turntable. But I would like to see Pro-Ject or another company offer similar functionality in a standalone box that can be connected to existing hi-fi equipment.

But I see Pro-Ject’s effort with the T2W as linking the vinyl revival with the home network using standards-based technologies like DLNA. Time to put that record on through the home network!

Synology DiskStation DS415play – an example of these full-function network-attached-storage units

Synology DSM vs. QNAP QTS: Which NAS is right for you? | Windows Central

My Comments

Increasingly Synology and QNAP have become strong rivals when it comes to full-function network-attached-storage devices that do more than what WD, Seagate and others offer. Here, they are made by two NAS specialists who are running high-end NAS-focused operating systems that can be run headless or with a screen and keyboard “head”. Some manufacturers like NETGEAR and ASUSStor are following on with Synology’s and QNAP’s efforts to join in the pack when it comes to

QNAP TS-251 2-bay NAS – another example of what a full-function NAS is about

offering full-function NAS units for home and small-business use.

Recent iterations of these devices typically have the same kind of computing power as a relatively-recent low-end regular personal computer but put this power towards file handling and serving. Most of them will support at least a two-disk RAID setup in the low-tier varieties with the mainstream models having four or five disk bays for a RAID 5 setup. The “brain” in these devices will be mostly an ARM-based CPU but higher-spec variants may use an Intel or AMD processor expected in a very low-end laptop computer. You may also find some NAS units like the Synology “play” NAS units running a graphics processor as a co-processor for media transcoding. A significant number of models will even support upgradeable RAM to allow them to work more quickly and handle more data traffic.

But the operating system is of a similar standard to one that would drive a regular personal computer. Most likely it would be a variant of a desktop Linux distribution and would be regularly updated as well as allowing users to install apps from the NAS vendor’s app store. Once you log in through a Web-based user interface or a keyboard / screen / mouse “console” attached to the NAS, you would experience a user interface similar to Windows, MacOS or desktop Linux running a graphical user interface.  But most of these user interfaces can’t allow for cut-and-paste between the host computer and the NAS user interface.

The apps will typically convey particular file-handling functions like syncing to online storage platforms, BitTorrent server functionality and DLNA-compliant media-server functionality. There is also apps that “tie” the NAS to native mobile-platform client apps supplied by the vendor to allow transfer of data between the NAS and a mobile-platform tablet or smartphone. It is typically a way to push a NAS as a “personal cloud” by working with a vendor-hosted “DNS-mapping” arrangement to allow you to upload content from your iPhone to your NAS even while you are out and about and connected to the Internet. This is in addition to various “client-backup” server tools for regular-computer platforms along with NAS-NAS backup tools.

Let’s not forget software like media-player functionality or IP-camera videosurveillance recording functionality. In some cases, there are various server apps for email or WordPress content management so you could easily purpose these units as a business information server. In some cases, adding peripherals to these NAS devices opens up paths for extra functionality with, for example, TV-tuner modules converting these NAS units in to Tivo-style PVRs that can share live or recorded TV content over the network.

QNAP’s QTS and Synology are very similar in many ways but Synology is focused towards simplified operation while QTS is focused towards taking advantage of faster better hardware. There are other similar full-featured NAS platforms like Netgear’s ReadyNAS or the ASUSStor NAS platform existing but there doesn’t seem to be the same kind of third-party developer base built up around these platforms.

But what can be done to make the full-featured NAS market better? One approach could be to allow the licensing of one or more of these NAS operating systems and app platforms to other companies on a “white-label” basis so they can launch their own full-featured NAS product range. This can avoid the need for a company who wants to develop their own NAS product to “reinvent the wheel” when building software.  As well, the creation of one or more large platform bases for NAS operating systems can give software developers the confidence to create software for these devices. Therefore it can avoid the home and small-business NAS market becoming like the games-console market which is focused towards vendor-specific solutions with a limited path for delivering additional software.

Personally, I would recommend the full-function NAS units of the Synology or QNAP ilk as being suitable for those of us who want more out of a network-storage device. In some cases, I would see it as appealing for an upgrade path for people who see their NAS device do more than just host files from your computer and share them to your Smart TV. Similarly it would appeal to those of us who want the basic abilities like DLNA media serving to be done in a more capable manner.

Plex gets closer to turning a NAS in to a PVR once coupled with a HDHomeRun broadcast-LAN device

IFA 2016: Plex live TV recording comes to Australia | Sydney Morning Herald

From the horse’s mouth

Plex

Product Page

My Comments

Previously I had covered the idea of a NAS being a PVR that records your favourite TV shows. This is whether it works alongside a dedicated USB or broadcast-LAN tuner device or a fully-fledged set-top device.

Recently, Plex was pushed as a “polished” media server for computers or NAS devices. This meant that it could show supplementary information about the movies or music you have on your PC-based media server or NAS if you used client-side apps on your TV or video peripheral.

But this software’s functionality has been extended to include PVR where it can record TV shows off the air and on to your media server or NAS. At the moment, it only works with the HDHomeRun broadcast-LAN TV tuners as its signal source and uses Gracenote as its source for the electronic programme guide. This means that the functionality is offered as part of the PlexPASS subscription program.

It seems to me that this feature could be destined for the servers that run the desktop operating systems but a good question to raise is if the DVR functionality will come about for NAS units because these would appeal more to those of us who run them as a media server. But personally, I would prefer that all of the platforms that Plex Media Server is written for have the upgrade for DVR recording.

To the same extent, it could also be about using a NAS as a “gateway” for a broadcast-LAN device when it comes to viewing live TV content on a tablet, laptop or similar computing device.

At least it is a different approach towards using a NAS and a broadcast-LAN device to perform PVR duties using your home network.

Synology DiskStation DS415play – demonstrating the value of transcoding content to provide to DLNA devices

Press Release

My Comments

An issue that can easily beset DLNA / UPnP-AV content-delivery setups is the fact that digital-image, audio and video content can be delivered in newer file formats and that it could be packaged for high-quality setups. A case to point could be 4K UHDTV video content which would work with the newer 4K UHDTV sets; or you could have audio content packaged in the FLAC lossless-compression file formats rather than MP3 or WMA file formats.

But the problem that exists is that you will likely to have older or cheaper equipment that can’t handle the higher-quality content types. Some devices that can handle the higher-quality content type may not be able to handle it in the file format it is delivered in unless the device’s firmware was updated to take the newer filetypes. Typically, this may ruin the experience because the device will typically throw up a confusing error message or show nothing.

A few UPnP-AV / DLNA Media servers do support some form of filetype or content transcoding with some Synology NAS units implementing this functionality at the hardware level. But there isn’t the ability to be sure that the NAS, broadcast-LAN tuner or similar device provides this kind of transcoding. The new DLNA 4.0 specification mandates that compliant server devices have to transcode the content that they serve if the client device can’t handle it directly.

The questions worth raising about this required function is whether this applies to filetype transcoding only or if it also includes functionality like downscaling a 4K video to Full HD for existing HDTVs for example. It shouldn’t also be about whether the transcoding takes place in the background for stored or downloaded media or only in a real-time fashion whenever legacy equipment wants the resource, something that would work with broadcast-LAN applications.

As far as NAS and DLNA media-server software design goes, one differentiating point that will exist would be the ability for the hardware and software to implement hardware-based transcoding. This is where a separate processor and RAM, like a GPU setup, is provided to transcode video content rather than the device’s main processor and RAM being used for the task. It is similar to what would happen if you use a computer equipped with a discrete video card or chipset to transcode some video content and this permits the main processor in the NAS to continue serving the files without having to transcode them at the same time. At the moment, the Synology DS416play, the successor to the DS415play which was the first NAS to offer this feature, is the only one that implements hardware transcoding.

Personally, I would like to see these devices offer transcoding for QuickTime and Motion JPEG video as used by some digital still cameras, and FLAC and ALAC lossless audio which is now valued as a high-quality audio format for “ripping” CDs or buying download-to-own music. This is because these formats are not universally handled in the DLNA network media sphere.

Other functions that are part of this version include catering to IPv6 networks which is fast becoming the way to go, inherent support for 4K and HDR video content, the requirement for a DLNA MediaServer to expose HD variants of more video filetypes and the VIDIPATH functionality being baked in to the standard which would be important especially for Pay-TV applications.

SELFSAT>IP, The World’s First SAT>IP Antenna, Gives Mobile Reception Devices Full Accessibility To Satellite Broadcasts – News release

SelfSat

Self-Sat IP range

My Comments

A Korean company had launched a new direction for satellite antennas where they aren’t a dish with the LNB antenna in front but a multiple-layered plate which masks a horn-based waveguide to the LNB antenna in the back. It is very similar to how a horn-style tweeter on some PA and hi-fi speakers works, allowing for efficient handling of very high frequencies.

This company, SelfSat, has allowed for this to materialise as a highly-compact satellite antenna that can be installed by just about anyone even in situations were the traditional satellite dish can be perceived to be ugly and subject to all sorts or regulations and rigmarole. As well, these antennas also are pitched at cheaper multiple-tenancy housing which isn’t equipped with a SMATV (common satellite dish) setup for satellite-TV reception.

But they took this further by offering a range of single-piece antennas that have integrated SAT-IP broadcast-LAN support with its own Ethernet connection. This allows he SelfSat>IP antennas to each serve up to eight SAT-IP reception devices with content concurrently.

There is also  2 LNB outputs on this satellite antenna so you can connect a multi-tuner PVR sat-box or multiple set-top “display-only” sat-boxes.

SelfSat even took this further with their Snipe Air lineup of mobile SAT-IP broadcast-LAN antennas which have their own 802.11ac Wi-Fi access point to distribute satellite TV to 8 concurrent Wi-Fi-equipped computer devices. I am not sure whether these only function as access points in that they create their own network or whether they can be part of an existing Wi-Fi network, contributing satellite broadcasts to that network.

The best application example that comes to mind for the Snipe Air SAT-IP antennas is the Tour De France where one or more of the “camping-cars” (motorhomes) that line the route of the cycle race use this antenna to pull in any of France Télévision’s coverage signals that the Astra satellite yields, serving one or more iPads or convertible laptops with vision of where the peleton is currently at. This allows for a judgement call about whether to run out to the roadside to see it pass or not.

The advantage that SelfSat pitches about Snipe Air compact satellite antennas is that they can be stored easily in a small car’s boot with room to spare or that, in the case of some models, they have the same roof profile on a caravan, campervan or motorhome as the typical roof-mount RV air conditioner.

What do I see of SelfSat’s SAT-IP efforts? I see them as a way to reduce the fuss associated with deploying the equipment necessary to receive satellite TV service. This could open up paths for many-endpoint mobile applications like the “Tour De France caravan parks”  familiar to anyone who watches that cycle race, or the road coaches that offer competitive road transport service across European borders.

Previously in my series on IFA 2015, I have covered the trends affecting personal and mobile computing like the arrival of the Intel Skylake silicon which raises the performance of portable computers along with trends affecting the home network such as 802.11ac Wave-2 Wi-Fi wireless. Now I am covering the technologies affecting home entertainment.

TV technology

There have been major strides forward with TV technology especially 4K ultra-high-definition TV.

Firstly, the cost of these sets is gradually reducing in such a way where they could start to appear in discount stores and supermarkets.

But another technology is appearing in the form of High Dynamic Range for video-content display. This is intended to create a more realistic image by preserving a high level of contrast between the brightest parts and the darkest parts. Here, the image would look like what you would see in real life like when you see the sun reflecting off the surface of the sea. Colour shades would be represented close to what they were to be, including the ability to handle bright exotic reds properly.

LG OLED TVs being launched at IFA 2015

LG have launched some flat OLED 4K TVs in the form of the EF9500 (65” and 55”) series and the EG9200 (55”) which are HDR-ready. With these sets, the flat-screen feature is underscored as being important for group viewing and whenever one is viewing on an angle which is something that curved screens cannot excel at. They also released a curved OLED 4K model in the form of the EG9100 series but this model omits the HDR feature. All these Smart TVs implement the WebOS 2.0 platform.

Samsung have covered all their bases when it comes to 4K TV technology by offering sets from 32” to 105”. They have announced that their UHDTV sets can be able to work with HDR material and these sets will benefit from this capability courtesy of a firmware update.

Panasonic have launched the CZ950 which is the first 4K OLED-based UHDTV to be launched by this brand. This 65” curved-screen set is tuned by Hollywood colourist Mike Sowia and is HDR ready.

Sony haven’t been quiet but launched their Bravia X91C series TV to Europe and Australia. This is while Philips launched their Ambilux TVs which use pico projectors to project images on to the surrounding wall to effectively enlarge the viewing area.

As for sources that supply video content in UHDTV, there has been some action lately on this front.

The 4K UHD Blu-Ray format has been launched as a way to cost-effectively deliver 4K material on Blu-Ray optical discs. It also has the ability to work with Dolby Atmos and other object-based sound-mix formats as well as supporting a digital media bridge function. Samsung has launched the first player capable of this format at IFA 2015.

As for broadcast content, Germany is moving towards DVB-T2 and implementing the HEVC codecs as part of this format which makes for traditional terrestrial broadcast TV being capable of being delivered in 4K UHDTV.

But there is more activity on the satellite-TV front with Eutelsat and SES Astra have been building out bouquets of 4K television content to be delivered this way. One example of this is the Fashion TV 4K channel that is being delivered by SES Astra satellites. CanalPlus is in on the 4K act as is Pearl TV, a German shopping channel. This is while Hessicher Rundfunk who is part of ARD is running demo transmissions via the Eutelsat Hotbird satellites. Sky Deutschland and a Scandinavian broadcaster have registered intent to establish 4K satellite content.

Audio Technology

When a consumer-electronics show has computing and TV as activities of focus, it is easy to forget about what is happening with audio technology. This is as the technology is being more focused around file-based audio and wireless multiroom audio setups of which there has been a lot of activity in this department.

LG Music Flow P5 speakers

LG has built out their MusicFlow Bluetooth audio platform with the MusicFlow P5 speaker that supports Automatic Music Play that starts playing your music when you come in range.This device can run on its own battery for 15 hours.  They also launched the SoundPop 360 which is a Bluetooth speaker that is the shape and size of a coffee cup and fires the music out around it. It has a playing time of 20 hours on its own battery.

LG SoundPop 360 Bluetooth speakers

These Bluetooth speakers support LG’s MusicPoint functionality which is effectively multipoint for Bluetooth speakers where you can connect two Bluetooth phones to the one speaker and play music through that speaker. There is also the DualPlay functionality where you can connect one phone to two LG Bluetooth speakers and set it up for improved stereo separation or many-speaker party-mode playback. The TV Sound Sync functionality allows you to link the Bluetooth speakers to a Bluetooth-capable TV and set up for better stereo or surround home-theatre separation or a private listening experience.

Samsung has answered LG on the Korean wireless-speaker front by offering 360-degree wireless speakers in the form of the R1, R3 and R5. These are cylindrically-shaped speakers rather than the previous egg shape and have a touch-based control surface so you can skip or recall tracks or “duck” the volume easily and they work with your Wi-Fi home network. Samsung’s Gear S and S2 smartwatches come with software to make them be remote controls for these speakers.

Philips have fronted up with the “Izzy” BMS range of Bluetooth speakers which can be synced to each other for a party-mode playback setup. These implement a pair of 2.5” full-range drivers in a bass-reflex enclosure.

Bang & Olufsen have fronted up at the IFA this year to show the BeoPlay A6 multiroom speaker which implements an unorthodox shape in order to fill a room with sound. The fact to remember about the way B&O speaker designs is that it isn’t just about their distinct looks but that these looks are to achieve improved sound dispersion across the frequency bands.This Danish-built speaker can work with B&O’s wireless iteration of the Beolink multiroom system or can cover all bases by working with Bluetooth or a Wi-FI home network supporting AirPlay or DLNA.

There is a desire by manufacturers and consumers to gang multiple wireless speakers together to play the same source. This is to permit improved stereo separation with that wider sound or to allow for “party mode” playback where all the speakers play the same music over a larger area. This extends to integrating subwoofers in to the equation to bring out that deeper bass, allowing the bass guitar or drum kit to come forward in popular music for example.

But there is a problem with Wi-Fi and Bluetooth setups where these networks are packet-based in the way they move data and there is a desire to keep the audio content in proper sync. This is limited due to chipset manufacturers and speaker / multiroom-system manufacturers designing their products so they can’t work with other products. There has been an effort in the right direction with Qualcomm’s AllPlay Wi-Fi-based system being implemented by different brands. Bluetooth could work harder on this goal for speakers that work in that domain while the Wi-Fi Alliance, IEEE Forum, the UPnP Forum and other alliances can work together to achieve this goal over IP-based local networks.

There is always a bit of action when it comes to new headphones and earphones to connect to your laptop, smartphone or tablet when on the train or plane. This is because most of us want to hear good sound from these devices to make our travel more easier and, in a lot of cases, these double as communications headsets for whenever we make and take phone calls on the go using the classic mobile or VoIP services.

Sony hear.on high-resolution stereo headphones

Sony have released their h.ear series of “cans” which come in different colours and are optimised for high-resolution sound. The first of these is the h.ear on which is a pair of closed-back circum-aural headphones that have a 5Hz-60kHz frequency range and are efficient for battery-operated devices by having a low impedance and 103dB/mW sensitivity. There is also a pair of h.ear in noise-cancelling earbuds that are part of the range.

These are pitched to go with their NW-ZX100 noise-cancelling Walkman file-audio player and the NW-A25 and NW-A26HN Walkman file-audio players with this model having noise-cancelling headphones.

Onkyo has used IFA 2015 to advance a pair of wireless earbuds which look larger than your typical earphones. Personally I see these earbuds a bit like a stereo take of those mono Bluetooth headsets that you slip over your ear to take calls in a hands-free manner while on the go.

Bose have used the IFA 2015 to premiere their Soundlink AroundEar Wireless Headphones 2 which are a pair of Bluetooth circumaural headphones based on their QuietComfort range of active-noise-cancelling “cans”.

Technics Grand Class G30 hi-fi system with media server

The traditional hi-fi hasn’t been forgotten about courtesy of Panasonic who are staging an aggressive comeback for the Technics hi-fi brand. For vinyl, they are revealing a prototype direct-drive turntable that is modelled on the classic SP-10 turntable and the SL-1200 “Wheels Of Steel” DJ turntable. This will come with an improved direct-drive motor. They have also fielded a pair of hi-fi headphones in the form of the EAH-T700 closed-back headphones which implement a two-way speaker design based around a 50mm main drive and a 14mm super-tweeter for each channel.

But they also have built out their stereo equipment range further with the Grand Class G30 hi-fi which is based around the SU-G30 network media player / integrated amplifier and the ST-G30 music server which rips CDs to solid-state disk in a bit-perfect manner, more the reason to buy your music on CDs. This device serves the music out to your home network using DLNA technology and uses FLAC or WAV files to store the music. They have also fielded a single-piece hi-fi system with integrated CD player which can also draw in music from your home network in the form of the Ottava Premium Class C500 system. As well, they showed the C700 speakers to go with that above system.

Next in this series, I will be covering the Internet Of Things which will encompass home automation and home appliances. Stay tuned!

Thecus Adds NAS With UPS Inside | SmallNetBuilder

From the horse’s mouth

Thecus

Press Release

N5810PRO 5-bay NAS Product Page

My Comments

A common issue with running a network-attached storage is making sure that the data is intact even if things go wrong with the AC power. This is something that can easily go wrong in regional and rural areas where there is a combination of overhead power lines and overgrowing trees and it just takes a tree or branch to fall down for the power to go out, or if your premises has ageing electrical infrastructure.

Typically this will involve the use of an uninterruptable power supply which effectively is a battery bank for your computer device, giving it a bit of time to properly shut down if the power fails. These are separate devices that you have to buy and plug your NAS into and most of them have the ability to signal to the NAS to appropriately write back the data and properly shut down when the power is out.

But Thecus has solved this problem with the N5810PRO which is a 5-bay small-business NAS that has an integrated uninterruptable power supply. This battery bank provides enough power to cause the NAS to write back all of data to its five disks and properly shut down, but you don’t have to have a separate device to achieve this.

It also has the other expectations of a small-business desktop NAS such as server functionality for a wide variety of tasks alongside even a server-side implementation of McAfee’s anti-virus software. As well, there are the 5 Ethernet ports which allow for serving 5 different physical networks or providing a “fat-pipe” from a suitably-equipped switch. Oh yeah, it also supports SMB/CIFS, DLNA, iTunes for the file transfer and can run multiple RAID volumes across the five disks.

But could I see the integration of a battery backup / UPS function in a NAS become a product differentiator? This could be more so with “small-business” models and the battery capacity could be a product differentiator in itself especially if the goal is to provide long-run failsafe operation.
