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.

Increasingly Google is encouraging companies involved in consumer audio-video to integrate Google Chromecast audio or video functionality in to their devices. This avoids the need to purchase and install a Chromecast dongle to benefit from audio and video streaming from online services.

Sonifi brought this concept in to the hotel scene so you can lie on your hotel-room bed and watch Netflix managed by your Android phone while Vizio, Sony and Philips are implementing it in to their TVs. Google even implements this concept in to their Google Fiber TV set-top boxes so that you don’t need a Chromecast dongle for this functionality. But Vizio has taken things further with Google Cast for Audio by offering this functionality in their latest range of sound bars.

Typically, you may think that a company may offer this function just to one soundbar or speaker base in their lineup but Vizio has offered it across the board for their up-and-coming SmartCast soundbars. These will work as Google Cast Audio devices where they can play online audio sources like Pandora or Spotify rather than being a “soundbar + Chromecast” device that adds Chromecast to your TV.

One article sees these soundbars as an answer to the Sonos multi-room sound system and nothing is further from the truth thanks to Google’s latest Chromecast software. Here, you could gang these speakers together in a “party mode” or have them playing different programs in a similar way to what you can do with Sonos. Let’s not forget that you can have something like Spotify or Pandora playing and the music isn’t interrupted if a call comes in or one of your phone’s apps throws a notification signal. It also means that the ringtone or the notification sounds don’t blast through your Google Cast setup’s speakers.

As for the price, the cheapest unit, which is a 38” 3.0 setup costs US$180 while the most expensive models being the 45” 5.1 setup that comes with surround speakers and a slim subwoofer runs for US$500.

Who knows who will launch the first stereo or home-theatre receiver or stereo system that has integral Google Cast functionality or if an existing multiroom audio platform will end up with Google Cast integrated in to it.

Google have integrated Chromecast in to their set-top boxes

Sonifi, a hotel-technology vendor is working on a guestroom-TV solution that integrates Google Cast functionality in to the hotel room TVs with the ability to stream via the hotel’s public-access Wi-FI network. This was one of the first “integrated Chromecast” setups that I have heard of where you can benefit from Google Chromecast functionality without you needing to plug in a Chromecast HDMI dongle in to your TV.

Now Google have taken this concept further with the Google Fiber TV package where the set-top box has the Google Cast functionality integrated in it. Here, the client device such as your laptop, tablet or smartphone is connected to the same home network as the Google Fiber TV set-top box like what would happen with your Chromecast. You would also perform the same procedures for streaming your app’s output or Web page through the TV as you would if you were using a Chromecast.

This concept can work well if Google continues to license their Google Cast software to other companies who manufacture smart TVs or network-capable video peripherals so as to keep this functionality as a product differentiator. Similarly, pay-TV providers and multiple-play telecommunications providers could have Google Cast as a differentiator for their set-top boxes that are part of their TV services especially where the market is highly competitive. The Google Cast Audio concept can also work well with network-capable audio equipment and Google could extend the logic so that if you are “Casting” an audio-only source like Spotify, Pandora or TuneIn Radio, these sources are by default sent to the Google Cast Audio endpoints.

It certainly shows that Google can put forward their Chromecast technology as something that can viably compete with the Apple TV ecosystem and could even coexist with Miracast and other platforms that are “possessed” by a particular brand.

Sat-IP makes the single-piece broadcast-LAN satellite dish possible

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.

I had provided some previous coverage about Panasonic’s AllPlay multi-room audio setup which implements Qualcomm’s AllPlay network-based multi-room audio technology. Here, I called out two stereos, the SC-ALL5CD single-piece unit and the SC-PMX100 three-piece system, that can stream broadcast radio and regular CDs that you buy from Amazon or JB Hi-Fi from their own tuners or CD players through AllPlay-compatible multi-room speakers.

Now Panasonic have refreshed their control app for their ALL series speakers and offered a video which shows what the refreshed mobile-platform app can do. It is part of a video playlist that highlights what the Panasonic ALL series stereo equipment and speaker systems are about.

Advanced wallpaper images–could this be real?

These LG 4K OLED TVs could be showing a tasteful wallpaper image while music plays

Increasingly, there is an interest in creating subtle wallpaper-type images and displays that can work effectively in the background whether with or without music.

Most home AV systems, especially those kept in a lounge area include a television or similar display device but if you intend to play audio-only content like music, you end up with a device that becomes useless in these environments. You typically end up with a blank screen which could be put to better use.

But you may want something that is effectively serving as a visual wallpaper that can exist in the background without destroying the flow of the conversation. This is more so if you are intending to play background music and something like a karaoke-style lyrics display or a music video may simply look out of place and end up more as a distraction.

Cafes like this could benefit from advanced video wallpaper displays rather than ordinary television

Businesses will also see this appealing as a merchandising tool for promoting their products and services and community organisations may want to exploit these concepts as a way to “set the mood” prior to running an event or promoting their efforts. Even cafes and bars would value the idea of creating a dynamic visual wallpaper rather than showing ordinary television content to set the ambience.

It is infact something that theatres and cinemas have practiced, typically before the programme session starts or during an interval where they show still images, typically advertising while background music plays.

What is being achieved with existing technologies

The concept has been tackled in various different manners such as DVD / Blu-Ray players, network media players and the like showing a screensaver-style image while audio-only content is being played.

A good example that stays in my mind is a Sony DVD/VHS combo that was used to play music CDs through the TV’s speakers and this unit showed a screen which changed between different colours while the music played. Similarly, some hotel TV systems may show a photograph and a text description of the radio station, or the radio station’s logo if the TV is being used to play a radio station, with better implementations showing the current song’s title or other dynamic information that is obtained from tha station’s RDS or similar datastream. Most regular-computer platforms have the ability to run a screensaver which typically is a pattern or animation that comes in to play when the computer is not being used. Or you could set up some network media players to pick photos up from your DLNA media server and run them as a slideshow while you have music playing from that same media server or another media server.

Sometimes, when people put up music on YouTube, they set up a visual wallpaper that accompanies that music. This may typically be a static image that never changes, or an image that may change at some point. A good example of this that I saw during a church get-together hosted at someone’s house was this YouTube “static-screen” video with the top 50 of the newer Christian contemporary praise-and-worship songs as its audio content while a static slide having a picture of a flying dove and “Because Your lovingkindness is better than life” appearing as a text quote at the bottom that picture. This is similar to how some people have created “continuous-music” DVDs which show one or more static images but have music playing. These and similar examples were based on a practice that WPIX-TV in New York City undertook since the 1950s where they showed a Yule Log burning in a fireplace (YouTube) with some classic Christmas carols and songs playing through the TV’s speaker.

How could this be taken further?

Live Wallpaper

There can be better ways to go about this. One would be to take a leaf out of Android’s book and exploit the “Live Wallpapers” concept which can allow you to create customised wallpaper images that can show real-time information or update the display in a dynamic manner. For that matter, Google could extend this concept to the Android TV platform which Sony is supporting for their 4K Smart TVs and Free have based their latest Freebox on. This could be in the form of showing selected pictures from one or more sources such as your photo collection or a stock-photo library, which could apply well to pictures of a city or country or some general pictures.

Cinemagraphs and short video loops

Beach shot

A beach image could be animated with the waves splashing in

A trend that is starting to become real is the concept of “cinemagraphs” which are video loops that appear like an ordinary photo but have subtle movement taking place. An example of this is a picture of someone sitting by the fireplace with the fire’s flames flickering, a Christmas tree with the twinkling lights or a beachside image with the waves rushing in. Even a close-up of someone may have some accidental movements like twitching or lips puckering.

Apple placed a revision in to the iOS 9 camera app which implements “Live Photos” that allows you to grab a short moment of animation just by taking that photo. Facebook and Tumblr even has integrated support for these “Live Photos” to be contributed to a user’s Facebook or Tumblr presence using the latest versions of the social networks’ iOS native-client apps. Third parties have opened up some desktop software and Websites which turn Live Photos in to animated GIFs which can be uploaded to Websites.

Microsoft’s research division is taking a step in the right direction by completing final research on “cliplets” where a short video can be broken in to “layers” with the ability to create separately-programmable loops for different objects in the video.

Enabling programmatic control of advanced wallpaper

Once a particular file type is defined for these kind of photo-video hybrid images to permit the creation of separately addressed video loops, it could be feasible to have these images driven by external properties like the time of day. This can range from one or mroe different text messages appearing under programmatic control to a graphic that is altereted depending on certain conditions.

An example of this could be a hybrid picture of London’s Big Ben showing the current time of day or a beachside image showing a dusk view when it is dusk. This could also allow for one or more text layers to be created to show text like quotes from a “quote library”, current song metadata, current time or weather information and the like. A media player that supports this file type could then show these for a user-defined time period then show another regular image or hybrid image for that time period.

Conclusion

This will become a constant issue as people want to use visual wallpaper on their display screens especially as these screens become increasingly large thanks to 4K UHDTV technology. Here, people may want to look at ways to keep these screens showing something appropriate during social events but not distracting their guests or patrons; or a business wants to keep their clients aware of their special offers.

Broadcast TV via the Internet

Lenovo Yoga Tablet 2 tablet

Tablets and smartphones could end up as the place to watch TV and you don’t need a tuner module

I have noticed that every traditional TV broadcaster that is running a “catch-up TV” platform is now streaming their regular TV channels live over the Internet using this platform. It is primarily pitched at those of us who use smartphones, tablets or laptops to view TV content “on the road” without the need for a TV-tuner module or broadcast-LAN tuner box and, in some ways, is being seen as TV’s equivalent to Internet radio.

Local content and advertising

This has opened up a can of worms when it comes to the kind of content available for people to view on their mobile devices, including the issue of regional content. In Australia, for example, the live-TV-over-Internet service primarily offers what is being broadcast to the metropolitan areas for the state capitals and this is ruffling local feathers when it comes to broadcasting news and public-affairs content relevant to the regional areas or providing airtime for local businesses to advertise their wares.

One of the core issues concerning the “live-TV-over-Internet” will be the locality of the editorial and advertising content including where is the content “local to”. If you listen to a foreign radio station’s Internet-radio stream using your Internet radio, you will know what this is about because of the talk and advertising that is local to that station’s city and there are people who like this either as a foreign-language learning tool or to acquire the “fabric” of that city if they lived there or have a soft spot for that area.

… as could laptops

This issue regarding TV could be rectified using streams that represent an area’s key markets and these streams have editorial and advertising content representative to those markets. The use of dynamic-ad-insertion technology would earn its keep with local campaigns being ran in the commercial breaks which could ameliorate the issues associated with local businesses not able to advertise their wares to their markets.

Area-specific rights issues

An issue that will impact “live-TV-over-Internet” will be area-specific rights for broadcast content. This is where a broadcaster buys exclusive rights to exhibit a particular sports fixture, movie or TV show in a geographic area, especially on a first-run basis. Typically these rights will be protected with

There will be the broadcast and customer-service issues being raised because a show normally available on a particular channel is not shown due to it conflicting with a local network’s existing rights.

Internet-only TV services

Another issue yet to come forward is the ability to gain access to “Internet-only” TV broadcasters which will come about as “live-TV-over-Internet” gains momentum. Such broadcasters are received primarily via your Internet service without having an over-the-air or cable/satellite presence.

These will manifest in the form of extra channels offered by a traditional broadcaster but not on the traditional broadcast platform, or an Internet-only broadcaster who would be able to run boutique content cheaply and easily due to low onboarding costs.

The issue that will show up with running an “Internet-only” TV service is how easy is it for potential viewers to discover these services especially if the goal is to run a scheduled-content service.

Content discovery

Another issue will be whether Internet TV will kill the traditional “channel-surfing” or “flicking” experience where viewers often flicked around the TV’s channel selector or jabbed the channel buttons on the remote control to look for something to watch. This is the main method where a lot of users discover newer radio and TV content. The current implementation would require you to run one catch-up TV / VOD app and browse the channels the broadcaster is offering, then run another app offered by another broadcaster and browse those channels to get the “lay of the land”.

This may be rectified through the use of a directory service similar to what has existed for Internet radio. Here, this could allow for a “channel-surf” experience along with the ability to browse for channels that offer content based on genres or other factors. Such a directory could be part of an electronic programme guide which encompasses all of the broadcasters and may work in conjunction with network or cloud PVR setups.

With Internet radio, multiple providers like vTuner and TuneIn Radio had set up to provide access to the Internet-radio streams, both those of AM/FM/digital broadcasters and of Internet-only stations. This means that an Internet radio or a mobile app would effectively have the same directory and different set manufacturers even had the ability to “brand” their own directories so as to be part of their user experience. This could then apply to Internet-based TV with different ISPs, smart-TV platform vendors, Websites and others running or licensing Internet-TV directories.

PVR recording

An issue that will also crop up is the concept of PVR recording of TV shows streamed via an Internet-based TV service. This will most likely be facilitated via an EPG so you can choose the shows from a programme grid or “what’s showing” list.

This could be achieved via a local-storage effort such as a traditional set-top device or a NAS that serves the home network; or a cloud-based effort based on the “software-as-a-service” model.

As what has happened with video recorders and traditional PVR devices, there will be the need to sort out copyright issues regarding the recording of shows. The new landscape in the context of “PVR as a service” will be highlighted in this context is the concept of “shared recordings” where one recording is made and many viewers view that single copy; or “private recordings” where each household has its own copies of the TV shows in a “digital locker” on the servers. Similarly, another issue that will show up is the portability of these recordings especially if the recordings are taken across national borders which would be a key issue in areas like North America or Europe.

The issue of portable recordings will come to the fore with us using mobile devices or a TV at another location like a friend’s home or a hotel to catch up on favourite TV shows.

Conclusion

What is becoming a reality is that television as we knew it is appearing via the Internet in addition to or in lieu of traditional broadcast-based pathways.

My Comments

Increasingly the 360-degree “virtual-tour” video is being seen as part of exhibiting a location or marketing a product. Even real-estate agents are using them as a tool to show off properties for sale, while TV serials are using them to give their fans a look-see in to the environments that the shows are set in.

But they are typically offered on Web pages that are best viewed in a browser with you moving your mouse up and down or dragging your finger up and down around a touchscreen or trackpad to pan around.  You may find that you zoom using your mouse’s thumbwheel or pinch in and out on a touchscreen or trackpad. Similarly navigating may require you to simply click or tap on where you want to go.

In some cases, they may also play properly with virtual-reality headsets of the Oculus Rift kind if you use an app for the device.

But what about viewing these 360-degree videos on that large-screeo TV or video projector. This may work if you throw that Web page on the large TV screen but you may not be lucky with some virtual-reality or 360-degree plugins working properly on the large screen.

Litlstar have tackled this issue through developing an app for the 4th-generation Apple TV set-top device that shows the 360-degree videos on the big screen. This exploits the Apple TV’s new remote control which has a trackpad by you using that trackpad to pan around.

This can be exploited on other smart-TV and video-peripheral platforms especially where some of these platforms are implementing gyroscopic remote controls or remote controls that implement multiple D-pads. Similarly, a games console of the XBox or PlayStation variety could be used as a tool to show the virtual-reality videos on a large screen.

It could also allow for one to watch some video content yet have an opportunity to “break off” in to a personal “walk-through” of that scene or building, yet be able to return to where they left off in the video content.

Who knows when Android TV or a subsequent Freebox décodeur will end up exploiting these abilities to enhance video content.

Those of us who own or are considering a Google Chromecast Audio device should apply the latest firmware update to this device. It will add two key functions to this device that will improve sound quality and useability.

If you connect a Google Chromecast Audio to one of the latest top-notch hi-fi amplifiers, you can let this amp rock when you feed the Chromecast “master-grade” (96kHz / 24-bit) FLAC files. You may be able to pick these files up from any “download-to-own” online-music store that courts audiophiles and offers the “master-grade” content.

As well, having multiple Chromecast Audio devices with this latest firmware can allow you to create a multiroom audio setup. Here, you use your Chrome extension program or Chromecast mobile app to create an ad-hoc synchronous playback setup involving one or more of these devices.

The low cost, typically of US$35, may make the Chromecast Audio appeal as a cheap option to connect a pair of active speakers, that 1980s-era “ghetto blaster” or a stereo system to your home network. It could even be seen as a “stocking-stuffer” gift that could earn its keep beyond the Christmas shopping season.

Free.fr, who is a strong player in French multi-play Internet market has become the first multi-play ISP to offer a 4K UHDTV channel as part of their IPTV content.

The channel, called Festival 4K and found on logical channel number 62, is focused on musical theatre, concerts and similar cultural events with these events being transmitted using 4K UHDTV technology.  This will require the 4K UHDTV to be connected to the Freebox Mini 4K set-top box which is based on Android TV software.

The initial subscription technical requirement was for the household to be connected to Free’s services via fibre-to-the-premises technology. But later on, it was discovered that you can use a VDSL2 or ADSL2 connection “dégroupée” (unbundled local loop) to Free and the connection has to have at least 15Mbps for reliable operationj.

This is another step with Free to lead the pack when it comes to competitive multiple-play services by opening up towards cutting-edge technology in the form of 4K UHDTV broadcasting.
