DLNA’s VidiPath Enables Subscription-TV Sharing At Home | TWICE

My Comments

I have given previous coverage to the DLNA VIDIPATH technology which allows you to use the home network to share pay-TV content around the home using compliant Smart TVs or desktop / mobile apps.

This article talked of a typical scenario where you have a PVR-grade set-top box provided by your pay-TV provider – the same kind of box as Sky+ or Foxtel IQ. The typical scenario for serving a TV in the master bedroom. the den or the games room would be to rent another set-top box from the pay-TV provider and have them pull coaxial cable to where it is installed. If you wanted to participate in the pay-TV provider’s “TV Everywhere” platform, you would have to download and register their desktop or mobile app to have cable-TV content on your computer, tablet or smartphone when you are at home.

VIDIPATH provides an authenticated method of allowing third-party devices to connect to the PVR via your home network. The application that was raised in the article was to have a Smart TV in the bedroom or den without the need of a set-top box, or to install an open-frame app on your computer or tablet to pull up live, on-demand or PVR-recorded pay-TV content.

But a situation that wasn’t raised was the fact that one is not likely to spend as much on secondary TV sets as they would for the primary one where they watch most of the TV content on. Either the main set may be upgraded and the set that served that role would be installed in the bedroom, a smaller TV would be placed in the kitchen or similarly-small area or a set that doesn’t have the same bells and whistles as the one in the main lounge area may be placed in a secondary lounge area.

Here, such TVs may not be VIDIPATH-enabled and would really need to be considered would be Blu-Ray players, Blu-Ray AV systems, network media players and similar video peripherals to be equipped for VIDIPATH. Why? This is because such devices can add this kind of functionality to an existing TV by simply using the existing TV as a display. It is in the same context as the VHS video-cassette recorders of the 80s where they had features like enabling cheaper and older TVs to benefit from remote control.

As manufacturers like Sony release Blu-Ray players and home-theatre systems that have “smart-TV” abilities, it wouldn’t tale long for them to offer VIDIPATH-capable versions of these devices as a way to enable the secondary sets.

In Part One of this series about the Consumer Electronics Show 2015, I covered the trends associated with personal computing while I covered the “Internet Of Everything” and connected living in Part 2. This part now touches on home audio and video entertainment technology which is being more about 4K ultra-high-definition video and high-resolution file-based audio.

TVs and Home Video

The 4K ultra-high-definition TV technology is starting to mature with more manufacturers running even 10 models with this resolution. But they are improving on this with cost-effective high-quality display technology with LG using Quantum Dot technology and Samsung using SUHDTV nanocrystal technology. As well, a lot of manufacturers are running with more of the curved or bendable 21:9 TVs in their lineup.

Sony have premiered their XBR900C series 4K UHDTVs available in 55” 65” and 75”, and being 4.9mm thick. They also are implementing the X1 processor for optimumly real colours across all their current 4K TV range. They also launched an ultra-short-throw 4K UHDTV projector at US$10000 which is bringing 4K closer to the bar.

Samsung is supplying a range of flat and curved 4K TVs with screen sizes ranging from 48” to 88”. These will appear across three model lines – the JS9500, the JS9000, and the JS8500 and is in addition to a curved 105” set which has the new nanocrystal display technology.

LG are running with 8 different 4K model lineups that are targeted at every price and room Sharp are implementing the Quattron yellow-dot technology in their 4K sets while TCL are putting their foot in the door for 4K UHDTV technology.

Another important trend is the control software for the smart TVs. Sony, along with Sharp and TPV Philips are intending to implement the new Android 5.0 operating system while Samsung is intending to run with Tizen and LG to implement a newer iteration of the WebOS operating system. Razer is even working on a games console that runs the Android 5.0 operating system. Panasonic are implementing the Life+ Screen smart-TV platform which is based on the Firefox OS operating system. In each effort, the companies are using established open-source operating-system code as part of their smart-TV platforms.

Let’s not forget what will appear on these sets Dish Network are ready for 4K content with the first 4K-capable set-top device in the form of the Joey set-top box. These can connect to 4K UHDTV sets with HDMI 2.0 and HDCP 2.2 . As well, they are offering a Sling IPTV service along with music-focused upgrades to their service delivery.

This is also being brought on by the UHD Alliance which is a group of big-name TV manufacturers and Hollywood content providers who are working together to provide high-quality 4K UHD video content. They have goals not just for high resolution but high dynamic range, a wider colour gamut and immersive sound as part of the content from creation to viewing on the customer’s TV set.

It has been augmented by the Blu-Ray Disc Association announcing that they were to start work on the Ultra HD Blu-Ray Disc specification. Panasonic have put a fair bit of input in to it and have even shown a prototype Blu-Ray player that plays 4K UHDTV content. As well, the Secure Content Storage Association have defined a secure-content-storage specification for consumers to store premium content on a hard disk or NAS and have established a “best-case” principle for selling 4K video content. This is where a customer buys a 4K-grade copy of content and they can have the best resolution that the playback equipment they are viewing it on can offer.

Cognitive Technology is working on a “Smart TV” content recommendation engine and wanting to partner with TV manufacturers and content studios to improve the concept of machine-assisted content recommendation.

As for the PlayStation Experience, Sony is providing the PlayStation Now streaming game service for the Smart TVs and their PlayStation consoles and offering at least 100 PS3 games to this service. This is in answer to them selling 10.5 million PS4s since model introduction and 4.1 million of them being sold through the past Christmas shopping season.

The doyen of streaming movies, Netflix, is working on a “Netflix Recommended” scheme for TV sets. The goal is to have certified TVs to switch to Netflix as quickly and as easily as changing TV channels. Here, the TV would have to have a dedicated Netflix button on its remote control, a suspend/resume function and to have Lilyhammer showing on Netflix within 2-3 seconds. This effort is being focused on the US market but will be rolled out around the world.

DirecTV are heading towards toe “over-the-top” path with the Yaveo Hispanic IPTV service. This will feature programming that has Latin-American Spanish dialogue and concepts focused at the Latin-American community.

Imaging

This year, there has been an increase in the number of consumer-grade video-cameras that can natively film in 4K UHDTV. Sony have put up a 4K lightweight handheld Wi-Fi-enabled Handycam along with a GoPro-style “action cam” that surprisingly works in this format. These implement various “steady-shot” so you can take better footage with the camera hand-held. The action cam can shoot 4K footage at 30 frames per second and also implements an ultra-wide-angle lens.

Panasonic has used this show to get their fingers wet with 4K UHDTV imaging and launched their first 4K camcorder which can also do high-dynamic-range filming. They also released the Lumix CM1 Android-powered digital camera which has a 1” sensor.

Kodak is now on to lens-style cameras that attach to smartphones like what Sony initially offered. But these are more lightweight than the Sony models so you can stuff them in your coat pocket without them being too bulky and use a Wi-Fi link to the host device and implement NFC-based setup for Android phones.

Networked Audio technology

There is still a lot of interest in the networked audio technology whether in the form of music and home-theatre systems or in single-piece wireless-speaker setups.

LG are advancing a range of new Wi-Fi speakers that are directly targeted to answer Sonos’s market dominance. This include a battery-powered portable model along with their speaker range based around the Music Flow concept. It uses a mix of technologies that are similar to Sonos, Spotify Connect and Google Cast. It also implements Bluetooth NFC-based “touch-to-play” experience and allows you to create room zones with stereo/surround speaker clusters and a party-mode with music around the house. They come in the form of the H3. H4 Portable and H5 which are similar to the Sonos Play:1 and Sonos Play:3 but can run at a louder volume without distorting and clipping. The H6 Soundbar negates the need for a hub device and has its own bass abilities without the need of a subwoofer. LG is to field a variant of this soundbar to snap at the heels of the Sonos Playbar.

Panasonic is using the CES 2015 to exhibit its line of Technics hi-fi components Stateside. This is to capitalise on the Technics name that was associated with some highly-capable hi-fi components through the 70s, 80s and 90s with memories of some classy amplifiers, turntables, CD players and cassette decks; and was reintroduced in to Europe during the IFA 2014. Here, they have the R1 Reference Class System with the SU-R1 network media player / control amplifier feeding the SE-R1 150w/channel digital  power amplifier which has those large power meters that Technics power amplifiers were known for and driving the SB-R1 3-way six-driver floorstanding speakers; along with the C700 Premium Class system which has a ST-C700 network media player / tuner serving the SU-C700 45w/channel integrated amplifier driving the SB-C700 coaxial 2-way 2-driver bookshelf speakers. It would be interesting to see how this renaissance picks up in areas like New York City – whether it has the same vim and vigour as what existed in the early 80s where hi-fi was really valued.

Samsung have launched their WAM-7500 and WAM6500 360 degree speakers which implement  Ring Radiator Technology. This leads to sound that is diffused around the listening area, but they have the look that would make them blend in to a “retro-future” environment typical of a 1960s or 1970s space-fiction movie. They can connect to regular AV gear, or be wireless speakers that support Wi-F home-network connectivity along with, Bluetooth connectivity. The WAM6500 is the portable one of the bunch while the WAM7500 is intended to exist on a table or bench.

They are also launching the Milk Music “online-radio” service as a music service that can work with their multiroom systems.

One of the main drivers has been Google Cast which is an app-based content-streaming technology that uses the home network to “pull up” content from your smartphone on TVs and stereo systems in a similar vein to Apple’s AirPlay setup. Here, it has been pitched at the Android TV platform but the audio aspect has been pitched at a few home-audio devices offered by different companies. This is also run alongside the Google Nexus Player which is based on the Android TV platform.

Cambridge Audio are releasing a range of network-audio devices that are manageable on their front panel or through a mobile-platform app. These use a highly-optimised digital-analogue path with Wolfson WM8740 DAC circuitry and can support sources from the home network via AirPlay, DLNA / UPnP AV, or online sources like Spotify Connect. The CXN is a network audio player that provides these services to an existing sound system while this function is integrated in to two 7.1 channel bridgeable surround-sound amplifiers – the CXR-120 rating at 60 watts / channel or 120 watts / channel when bridged to stereo; and the CXR-200 which comes in at 120 watts / channel or 200 watts / channel when bridged to stereo.

Sony have launched a pair of S-Trainer street-style headphones as wireless music players but also have sensors to help you with your workout. But they have focused on High Resolution Audio by releasing the NW-ZX2 Android Walkman MP3 player capable of playing Master-Grade audio files and has 128Gb storage on board infinitely expandable with a microSD card.

They also released the HT-ST9, HT-NT3 and HT-XT3 soundbars with some being connected to the home network and the STR-DN1060, and STR-DN860 network-capable home-theatre receivers. These are all capable of working with High Resolution Audio which is, again the “Master Grade” audio content worked at 24-bit 96kHz or greater sampling rates, said to be close to the sound of the master tapes.

Massive are fielding a set of Doctor Who Bluetooth speakers which look like either a Dalek or a TARDIS. They have the classic effects associated with this show such as the “Exterminate” call or the TARDIS’s cloister bell. This is also alongside a pair of headphones with some Doctor Who iconography..

Gibson (who now have Philips Audio, Onkyo and TEAC) is now selling the Trainer exercise supra-aural Bluetooth headset as a way of being noticed that it has consumer-audio prowess rather than just Les-Paul-style musical-instrument prowess. This headset has an LED so you can be noticed at night and it also has a button to “duck” the audio so you can hear what is going on around or to talk with someone else. As well, the earpads are designed to be washable.

Audio Technica have refreshed their headphone lineup with some waterproof “sports-grade” intra-aural devices including a headset. They even pitched a set of intra-aural earphones that are “up-to-snuff” for audiophile applications. They also launched a set of noise-reducing headphones with one that could be sold in Europe for EUR€100 and a pair of gaming headsets – one being open-backed and one being closed-backed for different frequency response characteristics, but these headsets are pitched at the same price.and can serve as wired mobile headsets. Let’s not forget their other point of prowess with record-playing equipment where they released an entry-level fully-automatic turntable equipped with their own cartridge.

The final part of this series will cover some computer and smartphone peripherals of not but will also cover how the home network is to evolve courtesy of some new connectivity-technology improvements.

Bilan: la Freebox Révolution a quatre ans | Freenews (French language / Langue Française)

My Comments

As a consequence of the highly-competitive triple-play communications service market in France, Free had developed one of the “n-boxes” that has a lot more that is expected for this class of carrier-supplied equipment. Now this device, known as the Freebox Révolution, which is available in just about all of France for EUR€29.95 a month as part of a very tasty triple-play pack, has reached its fourth anniversary.

I have given a fair bit of editorial space to the Freebox Révolution including citing it as an example device in an article about setting up for Internet in France. This is due, not just to its exciting Philippe Starck design but due to the increasing amount of functionality that this device has come with and received over the four years. Here, Free kept with a program of frequent firmware updates which weren’t just about fixing up technical problems but were also about adding functionality to these devices, some of which I have drawn attention to on HomeNetworking01.info.

The Freebox Server was more than just a VoIP gateway with DECT base-station and wireless broadband router. Here, it had DSL and fibre support on the WAN side of the equation and a 250Gb NAS. There was even the ability for the unit to be a media player for Apple AirPlay, DLNA or online media, including playing audio content out via integrated speakers or through external active speakers. The LAN side had a four-port Gigabit Ethernet switch along with 2.4Ghz three-stream 802.11n Wi-Fi, but the Freebox Révolution comes with power-supply units that have integrated HomePlug AV-Ethernet bridges. The newer iterations had been upgraded to HomePlug AV500 and the Wi-Fi on newer releases was upgraded to a dual-band dual-radio variety. Let’s not forget that some of the newer variants even came with a Femtocell that provided local mobile-phone coverage for your home as part of Free getting their paws in to a mobile-telephony service.

Firmware upgrades even had the Freebox Server acquire full Apple compatibility along with being a VPN endpoint router and one of these upgrades was fashioned as the “Freebox OS” with an interface very similar to a newer Linux distribution, one of the mobile-platform operating systems or something you would get with one of the newer high-end NAS devices. The server functionalities included UPnP AV / DLNA, Apple Time Machine, iTunes Server and a BitTorrent server, known as a “seedbox”.

The Freebox Player which served as the “décodeur” for the IP-based TV component of the triple-play service was infact a “full-blown” 3D Blu-Ray player, games console and digital-TV tuner. The gaming functionality was part of an app-store that Free operated, which was to the same standard as most smart-TV platforms, if not better. This device was also controlled by a “gyroscopic” remote control which communicated to it via Zigbee RF technology and supported “gesture-driven” operation. Lets not forget that this was a DLNA-capable media player which gained MediaRenderer functionality from a subsequent firmware upgrade. This device also served as an Internet terminal for the TV screen and even had the ability to interact with most online services courtesy of either the Web view or a native-interface “front-end” that came with one of the firmware upgrades or downloaded from the app store. There was a firmware update that give the Freebox Player “Shazam-like” song-identification abilities.

The Freebox Révolution raised the bar when it came to the concept of a premium triple-play “n-box” offer with the competitors offering systems that had very similar functionality and aesthetics. Examples of these include Numéricable’s La Box and the Neufbox Évolution. As well, I had a casual conversation with someone who came out from France and they even mentioned about someone they knew having one of these devices and being impressed with what it could do.

For me, I have viewed the Freebox Révolution as the flag-carrier for the competitive French Internet market because of the way the carriers can add more value to the equipment they supply their customers. In this way, I would place this device alongside the TGV or the Channel Tunnel as a symbol of French technological progress.

Happy Birthday, Bonne Anniversaire, Freebox Révolution!

Another major trend that has come about over the past five years is increasing interest in “connected entertainment”. This has been augmented with the role of smartphones, tablets and computers having access to online content services, typically through natively-coded client-side apps.

But it is also about a surge in the availability of traditional devices that are associated with entertainment being connected to the home network and drawing down online content from various sources.

Network-capable entertainment devices

Increasingly we are purchasing network-capable entertainment devices that are fit for use in the main living or family areas of our homes.

Firstly, most TV manufacturers are supplying “smart TVs” that have network connectivity and access to online content services. Typically the manufacturers, primarily the “big-name” companies are offering this towards mid-range and premium models in their product lineups. This feature is also being extended to Blu-Ray players, “home-theatre-in-box” systems and the like so you can add this feature to existing TV sets which is important as TV sets last a long time and are capable of being “pushed down” to secondary viewing areas. It is also a key feature for any of the newer 4K “ultra-high-definition” TVs that show images that are sharper than the regular Full HD TVs on the market.

Similarly, network-capable music-playback devices are reaching standards that befit high-quality music reproduction. Here, these devices are either as “wireless speakers”, integrated music systems or hi-fi components that can be connected to existing hi-fi systems.

The “wireless speakers” are single-piece tabletop speaker systems that connect to the home network in a manner similar to what Sonos envisaged with their products. Here, you can have a group of these speakers that are connected to the same network play the same audio content without them being out of sync. Most of the setups may work in a “party-mode” setup where they play the same content whereas an increasing number of these speakers can allow you to set two like units up as a wirelessly-linked stereo pair for increased stereo separation or wirelessly link a subwoofer to the speaker to provide some extra bass. A trend that could easily come about is to have a wirelessly-linked multiple-speaker setup for surround sound, which could make this concept more appealing because of the absence of wires.

At the moment, Wi-Fi-based multiroom wireless speakers will work with other speakers that implement the same technology, typically by having the same or compatible chipsets. This is because no standard has been defined for these kind of speaker setups.

Another device that is being considered highly important for the “connected entertainment” world and is something that every home network will have to have is the network-attached storage appliance. These devices work as “always-on” media servers that can provide audio, image and video content and most, if not all of them implement UPnP AV / DLNA and iTunes / DAAP media-server functionality to do this on a level playing field. This means that you don’t need to run a desktop computer all the time to make the latest photos or the music you ripped from your CDs or downloaded from iTunes or similar services available to your smart TV or your network-connected stereo equipment.

Online Content Services

Previously, online content services were typically Internet radio services which offered global access to Internet-hosted simulcasts from various broadcast radio stations and networks. I saw this as the “new shortwave” because you could hear a radio station that is local to a particular city or town through this setup and these have been facilitatied by a few Internet-radio directories like TuneIn Radio and vTuner.

Now we have seen the arrival of the “global jukebox” in the form of music-streaming services like Spotify, Deezer and Pandora. These services allow you to legally stream an album, song or playlist via the Internet and work either for free with advertising or for a modest monthly charge. They are becoming a way to, for example, sample music you are interested in or even just listen to music for a modest cost or for free.

For music, the buy-to-download business model still exists courtesy of the likes of iTunes, Google Play, Amazon or most other online stores. There are some label-direct music stores that offer music on a “buy-to-download” basis. Most of these services offer the music as CD-quality 320kbps MP3 or 256kbps AAC files for each album track but some are offering them as master-quality FLAC or similar files. As well, most of these tracks are being made available as single tracks for pennies’ worth for those of us who want to construct the perfect playlist.

This is also including music distributors and online retailers like Amazon who sell us vinyl records or CDs that come with “pre-ripped” MP3 files that are available to download. For most of us, this avoids the need to rip the CD or to copy the record to the computer’s hard disk so it can be heard over the network or on our portable devices.

Online video is mainly driven by the likes of streaming services like Netflix who are even producing their own content as well as licensing other parties’ content. They are also being augmented by “catch-up TV” services where one can view one or more previous episodes of a TV series “on demand” after it was shown. Because these services are yielding high-quality content, they have led to people in the US abandoning their cable-TV services and watching content on these services.

Most such services are nowadays being delivered via set-top boxes that connect to your home network and implement a native front end to these services. But, as smart TVs come on the scene, anyone who offers a video-on-demand service has to provide a native front-end for the main smart-TV platforms.

In some parts of Europe, ADSL and fibre-based next-generation broadband is being used to deliver pay-TV. This is more so as part of telecommunications companies offering a “single-pipe triple-play” service to their customers where one connection to the customer’s home carries broadband Internet, landline telephony and multi-channel pay TV.

They have also implemented a “hybrid broadcast broadband” platform for television where it is becoming feasible to provide TV content services, including interactive TV, by interlinking traditional broadcast TV with content available via the Internet. Broadcasters primarily use this to deliver a supplementary video-on-demand service such as a catch-up TV service to the main TV set.

At the moment- there isn’t a level playing field for providing video content on an “electronic sell-through” or “download-to-own” basis in a similar way to what is being used for audio content. There are still issues with digital-locker services or digital-rights mechanisms binding users to particular content platforms or the risk of people losing access to the content they bought if an electronic-sell-through platform ceases to exist. They are not at a point where you could buy a movie or television series online and download it to a NAS for viewing at home knowing that you still have access to the movie even if the vendor goes off-line.

Conclusion

It will take some time to bring some video content-delivery services to the home network in order to have it accessible on the main TV set, but the home network has become an entrenched part of our entertainment lives/

Yamaha Audio

R-N301 Natural Sound Network Receiver

Catalogue Page (Australia, Europe)

My Comments

A class of hi-fi component that is missed out on when it comes to network audio and AV is the stereo receiver. This component is more focused about reproducing music in stereo from radio broadcasts or other hi-fi components like CD players or turntables. This is compared to the home-theatre receivers which are more focused on reproducing surround sound, typically from attached Blu-Ray players, cable TV or other video sources along with support for radio broadcasts.

Onkyo previously released a network-capable DLNA-compliant stereo receiver in the form of the TX-8050 but Yamaha have released a more affordable unit which also works with Pandora, Spotify and co. This receiver, known as the R-N301 Natural Sound Network Receiver, has these abilities along with support for AirPlay and DLNA control and can put the music out at 100 watts RMS per channel (0.2% THD, 8-ohm speaker load, 20Hz-20kHz frequency response).

One omission that may affect some peoples’ buying decisions is the lack of a phono preamplifier so you can connect a turntable. This may be of concern especially with vinyl coming back in to vogue but is available in a more expensive network-capable stablemate in the form of the R-N500 Natural Sound Network Receiver.

But what I see of this is that Yamaha is joining Onkyo in providing a “full-width” stereo receiver that can be part of the home network but can be used in a lounge area like the formal living room where music, reading and other similar activities is the main activity.

Introduction

In October I had visited the Australian Audio And AV Show which was hosted at the Intercontinental Melbourne The Rialto hotel and this was about observing the way hi-fi and home AV were progressing especially on the Australian market.

Video Technology

Regular readers may have seen some coverage about the new 4K ultra-high-resolution TV technology and I had a chance to see this technology in full flight for myself at this show, courtesy of Sony. But the Sony representatives have remarked that this technology’s appearance in the broadcast-TV context is still a long way off especially in Australia. Here, they remarked that 4K UHDTV content will have to be delivered in a packaged form i.e. Blu-Ray Discs, file-based video delivered via USB hard disks or via the home network.

BenQ and Epson presented Full-HD video projectors that were more or less targeted at home-theatre setups and were demonstrated in that context.

Audio Technology

The two main distribution trends that are hanging on for quality hi-fi sound reproduction at the moment are the classic vinyl record or file-based audio content delivered via the home network.

The classic vinyl record

The classic vinyl record is still focused on new-cut records that have been mastered using newer techniques that permit increased dynamic range. These are played on turntables that are equipped for improved stability and the sound path implements high-grade components from stylus to speaker.  The equipment that I have seen in operation at this and previous Australian Audio And AV Shows is more for those who value the vinyl format as a hi-fi content source rather than to be part of the image.

One manufacturer even implemented an “optical cartridge’ that uses reflected light rather than friction to follow the stylus’s vibrations in that groove. Here, this cartridge can be fitted to most tonearms associated with high-quality turntables and is connected to a special preamplifier which exposes this cartridge’s output as a line-level signal. Here, it was about using light as a tool to “follow” a source of acoustic vibrations before it is converted to an amplifiable electrical signal as well as being able to use this cartridge with most turntables.

One turntable that was exhibited here that is considered a proper specimen for bridging the classic medium with today’s Sonos speakers or the computer is the VinylPlay “integrated phono stage” turntable. This has a similar build to most of the recent Rega, Pro-Ject or similar turntables that properly welcomed back vinyl and has what is expected for stability, but has a built-in phono preamplifier with digital and USB outputs as well as line-level and “cartridge-direct” analogue outputs. Another feature that increases its useability, especially for a manual turntable, is a distinct arrow on the cartridge’s front that indicates where the stylus is, so you can be sure the needle is where you want it i.e. on that record. What I see of this USB-equipped record player is that it isn’t about a gimmicky flimsy unit but one that can properly bridge the classic records to a lot of equipment.

Digital audio

On the other hand, the quality of digital audio, both in the recordings that are distributed and the “file-to-speaker” playback chain has improved. For example, the “high-resolution” file-based audio content has been represented here as being above the 44.1kHz 16-bit CD-Audio or the 48kHz 16-bit standard-play DAT specifications that was “cemented” for digital audio recording and playback in the late 1980s. Typically, audio that is made to this specification will resolve towards 24-bit 96kHz or 24-bit 192kHz digital-audio streams and this will either be in the form of FLAC or similar audio files and it yields what could be perceived a clearer sound. It is also augmented through the use of digital-analogue converters or digital-amplifiers that are designed to “pull more out” of a digital-audio stream with very little in the way of unwanted sound artifacts.

Equipment that was designed to cope with the “master-grade” high-resolution digital audio sound could also bring out the best from classic digital audio content as I had seen for myself with the Sony MAP-S1 network-capable CD receiver. This unit was set up completely as a system with a pair of the Sony SSH-W1 3-way bookshelf speaker and I had let it perform with my Whispers “Love Is Where You Find It / Love For Love” CD. Here, it came through clearly with the soul music, yielding that desirable “punch” to the sound yet coming across clearly.

The home network as part of digital audio

Again, the home network is still considered as part of enjoying digital audio. This is typically with a network-attached-storage device or music-focused media server holding all the music and network media receivers playing the music that is held on the NAS or from one or more online sources. It has been brought about with the larger size of music files that are prepared according to high-resolution “master-grade” standards and these files being offered on a “download-to-own” basis.

There were a few of the network audio receiver devices which were built to work with an external digital amplifier or digital-analogue converter rather than doing the digital-analogue conversion themselves. These were pitched for use with the top-notch digital-analogue converters and digital amplifiers the were becoming part of a high-grade digital-audio setup.

One of these was Auralic Aries network audio bridge connects between home network or online content and DAC,  DLNA support and works as Media Renderer. Connects to DAC via USB, AES/EBU (Digital XLR), SPDIF Coaxial or SPDIF Optical, network via 802.11a/g/n Wi-Fi or Ethernet. As well, it works with Linn’s Songcast “network sound card” software so it and the DAC work as a computer sound card. This device is controlled using Auralic’s Lightning DS mobile-platform app but has the ability to work with an Auralic remote control for ad-hoc program selection and transport control.

This small network-media bridge  was fed by a QNAP NAS full of music and passed its digital signals via USB to an Auralic Vega digital-analogue converter. It in turn passed the analogue signals to the Auralic Taurus Pre control amplifier feeding a pair of Merak monobloc power amps to drive a pair of floor-standing speakers.

Another was the latest iteration of the NAD Masters Series of premium digital hi-fi components with the M12 digital control amplifier and M22 stereo power amplifier being driven by the <model number> digital media player. This unit appeared at previous Australian Audio And AV Shows and was an example of an optical-disc transport and network audio bridge device.

There is an increased number of dedicated music servers or “ripping NAS” units being presented at this year’s show with some of them working as the music servers for their distributors’ rooms. Two examples included the RipNAS Solid v3 and the Naim HDX. The Cocktail Audio music servers still appeared but were on static display, not serving an active system. As always, Naim pushed their music servers in to service as content libraries for two music systems, this time it was the NDS which was serving the Statement ultra-premium hi-fi system and the mu-so wireless speaker.

Lifestyle and multiroom audio

Lifestyle audio still had its strong presence at the Australian Audio And AV Show. This was mainly dominated with single-piece wireless speakers and soundbars with some of the soundbars being used to play music. Some of these systems implemented subwoofers to “lift” the bass response, whether they were packaged with the soundbars or simply as to be set up to work with one of the wireless speakers just to add that bit of “bite” to the sound.

These were part of the multiroom trend where you can have music systems located in different rooms  There was even a seminar on the multiroom audio trend and this highlighted the arrival of the home network and online media as key drivers of this technology.

But they highlighted the fact that different companies, including chipset and technology vendors, are working on their own solution to permit audio content to be delivered to many speakers via a packet-based network like the typical Wi-FI or Bluetooth network in sync without jittering or packet loss. This was to open up paths for situations like 2 wireless speakers being set up to work as a true stereo pair with proper separation or “party-streaming” setups with multiple speakers and sound systems. At the moment, most of these systems can only work with equipment that implements the same technology and I am not sure whether these systems can work properly on a multiple-access-point setup such as with a wireless range extender or traditional setup with access points connected via an Ethernet or HomePlug AV wired backbone.

Denon had exhibited their HEOS Multiroom setup consisting of three different single-piece wireless speakers while Definitive Technologies used Room 320 for showing a highly-complete wireless audio system. This one consisted of a few different single-piece speakers, a soundbar, a wireless amplifier and an “on-ramp / off-ramp” audio adaptor module for their PlayFi-based system which uses a small Wi-Fi network as its carrier. Polk also made us aware of their wireless multiroom system which was based on one of the existing synchronisation technologies.

Ruark Audio had surfaced this year with a collection of table radios and music systems. This was headed by the R7 Radiogram which has a CD player, FM/DAB/Internet radio, Bluetooth playback, DLNA MediaRenderer functionality and access to online services. Here, it is styled in a form similar to the archetypal “radiogram” or “console stereo” that served as the main household music system for most people through the 1950s and 1960s and is something that is pitched at the “baby-boomer” generation.

Naim also came to the fore with a single-piece wireless speaker called the mu-so. This could pull up content from a DLNA server or online content services (think Spotify or Internet radio), AirPlay, Bluetooth A2DP with aptX amongst other sources. It is primarily controlled through Naim’s mobile app and works tightly with their multiroom streaming setup. But this uses a 3-way speaker arrangement for each channel with each driver having its own amplifier and it also implements DSP technology which Naim implemented in the sound system used in the newer Bentley cars.

The Headzone still appeared, representing the increased role that headphones and earphones played in the personal AV life. The theme here still was to listen to music or video content through the headphones rather than have them available to hear the other party of a phone conversation or hear the sound effects associated with computer games played on our mobile devices. But I would see these still play a strong role with VoIP or mobile communications services that implement “HD Voice” or newer telephony-audio technologies which sound as good as AM radio, if not better.

They still are important for the connected life as we use them to be able to listen to music, video and games effects from our computing devices privately. Most of the premium sets were demoed with dedicated headphone amplifiers but some of the headphones were either connected to regular integrated amplifiers or the headphone outputs on some CD players, or simply available for us to plug our mobile devices in to.

It is also worth being aware of the efficiency that particular headphones show up, especially if you are targeting them for portable use with battery-operated equipment. Here, I had discovered this for myself with the Sony MDR-10RC headphones I previously reviewed and a pair of newer portable-focused headphones I am using as my regular set and tried both of them on the Sony SBH-52 Bluetooth adaptor associated with my Samsung smartphone. I ran the Bluetooth adaptor at the same volume setting on both headphones and the portable-focused headphones sounded louder but not as clear compared to the MDR-10RC set. The fact that one pair may sound louder at the same volume level compared to another, thus being more efficient, may be of benefit with that battery-operated device because you are not “running the device hard” for the same volume level, thus not drawing on the batteries more.

Speaker technology

A lot of the hi-fi systems were demonstrated with the conventional-architecture speakers, some of which were the traditional floor-standing types or most of which were the bookshelf speakers that were set up on speaker stands. These still yielded strong unassisted bass response with the amplifiers at “ideal listening volume”.

On the other hand, another firm were exhibiting a surround-sound setup which used flat-panel speakers in a traditional quadraphonic layout but these required the use of a subwoofer to convey the bass response.

Conclusion

What the last few iterations of the Australian Audio And AV Show have underscored was the fact that recorded-music reproduction has taken many methods and has improved on the methods. The signal path from the content source, being a vinyl record, optical disc or a file held on a computer or network-attached storage, to the speakers will under a continual path of innovation and even the medium itself will under a path of innovation.

I have provided a Spotify playlist of some of the songs that have heen played here.

My Comments

The XBox 360 games console originally came out with the ability to play content held on a UPnP AV / DLNA media server and was one of the first devices pitched to the mass market to do so. This also underscored the multi-function abilities that was the direction for game-console design.

But, when the XBox One came out, this console didn’t have much in the way of media playback beyond DVDs and some online services. This is even though Microsoft had touted it as being part of one’s media-consumption ecosystem with highly-integrated media behavour.

Now a major “version-2” software update has opened the doors for a file-based media player that allows you to play media from USB Mass-Storage Devices as well as that which exists on a UPnP AV / DLNA media server that is on your home network. This is also augmented by the support for a plethora of file formats like MPEG2 TS and MKV. The Register article placed doubts on support for MKV due to it being used for illegitimate torrented material, but it could also be about “prepping” for access to legitimate “download-to-own” video content.

It also adds extra paths for access to broadcast content through your XBox One such as a USB DVB-T tuner module for digital TV in Europe and Oceania, or access to the DLNA-based broadcast-LAN tuners like most SAT-IP compliant satellite units or an increasing number of the HDHomeRun units available for North American or European use.

This is a step for Microsoft to claw back the multifunction abilities that these consoles have and make them earn their keep as a video solution for the secondary lounge area, college dorm or other similar living areas.
