Mirroring your computer onto any HDMI display with Airtame wireless dongle

Here’s yet another option for wirelessly mirroring your computer screen to another display, but don’t worry: This one is rather impressive. Airtame, the creation of a group of Danish folks, is an HDMI dongle that links your PC — be it running Windows, OS X or Linux — to whatever display it’s plugged into over WiFi. Installation is a breeze: All you need on the PC side is just the software, and from there you can choose which dongles to beam your screen to. Yes, dongles, because you really can beam one PC to multiple screens, thus beating Miracast. We also played a game on one of the laptops, and the response time on the remote display was surprisingly good.

UHD to the Home – Ultra HD over the Internet

As part of its presence at the Commonwealth Games, BBC Research & Development currently has a number of ultra high definition (UHD) television screens at both the Science Centre in Glasgow and New Broadcasting House in London showing live coverage of the games. These screens are open to the public for the duration of the Commonwealth Games and free to view for visitors between 10am and 5pm in Glasgow and 12 midday to 3.30pm in London.

The pictures and sound for these screens is being delivered over the internet – from capture, through the full production chain, and finally to decoders and displays in the demonstration areas. This entire process normally requires very specialised and expensive television broadcast equipment but in this case it is all being handled using normal IP networks and commercially available computing equipment. Below you can see a short video produced by R&D engineer Alia Sheikh which explains the work the department has been engaged with in this area and the reasons why BBC R&D thinks IP delivery is the future for TV delivery.

For the Commonwealth Games BBC R&D’s IP TV delivery infrastructure is spread over a number of different locations to demonstrate the flexibility that an IP based production system brings. While pictures and sound are being captured in the venues, the audio gallery providing the commentary is in London and the television production gallery is located in Glasgow. Below you can see how our IP based end to end infrastructure is spread across the UK to deliver UHD TV to our public demonstration areas.

While delivery of television by IP is on the increase, a lot of people still receive their television using traditional transmitters and receivers and will do so for some time to come. Not all of the UK has reliable high speed internet connections so alongside IP delivery, the department is also demonstrating the transmission of UHD content over the existing Digital Television Transmission (DTT) network. BBC R&D are working with the rest of the broadcasting industry to ensure that the standards exist to distribute UHD content to as many people as possible no matter the delivery method.

Motion Blur – The Challenges of UHD

Beyond the challenges of delivering UHD content to people’s homes there’s also the issue of how to get it working properly once it gets there. One challenge is that with higher visual definitions motion blur becomes more of a problem for video images, especially with fast moving subjects like the athletes at the Commonwealth Games.

One solution is to increase the frame rate of the television (the rate at which the image on screen is refreshed) from 50fps to 100fps. To sharpen motion, you can also shorten the camera shutter speed, but at conventional frame rates this leads to judder. A frame rate of 100 fps enables the eye to fuse motion in a realistic manner, even with a short shutter opening and is also high enough to avoid visible flicker. BBC R&D is involved in ongoing discussions with other European broadcasters to create standards for UHD frame rates. The image below shows a comparison of shutter speeds of 1/100 and 1/300 of a second.

Exciting New Opportunities

Along with the technical challenges IP-delivered UHD TV presents to the engineers at BBC R&D, it also provides a host of new production and editorial opportunities. One major advantage of building an IP based system is how configurable it is.

A television studio is a collection of very specialised pieces of equipment, very often with only one purpose each – a vision mixing desk for example or a preview monitor. Moving from a hardware to a software based system means that devices can be reconfigured to the needs of different production teams quickly and at little expense. The gallery production equipment in R&D’s experimental IP based television production gallery uses consumer computing hardware so a tablet can be a production schedule one day and a sound mixing desk the next. Or both. This reconfigurable nature of IP based production drastically reduces cost and increases working flexibility.

The BBC has always delivered high quality crafted television, first in black and white, then colour, using both analogue then digital delivery methods and most recently moving from standard definition to HD. UHD TV and IP based production are another evolution of the art form that provides the organisation with yet more exciting opportunities to make the best television we can and deliver it to audiences in increasingly cost effective ways. BBC Research & Development’s work ensures that when the UK is ready to switch to UHD, the BBC will be as well.

To take a look behind the scenes at a working IP television production gallery please visit us at the Glasgow Science Centre between 10am & 5pm for the duration of the Commonwealth Games. You can also watch live UHD coverage of the Commonwealth Games delivered both over IP and using digital television transmitters. Finally you can get hands on with some of the exciting new experiences that UHD video and IP delivered TV make possible including a chance to look around a 3D live video of the Hydro Stadium using the Oculus Rift headset.

Samsung 105-inch Curved UHD 4K TV

Today Samsung announced the availability of its biggest curved screen TV ever. First shown at the 2014 CES, the 105-inch UN105S9W UHD 4K TV sells for $119,999.99 . Unlike Samsung’s other curved models which incorporate the HDTV and UHDTV standard 1.78:1 aspect ratio, this one uses an ultra wide panel with 2.37:1 aspect ratio. More details after the break.

The UN105S9W can be ordered this week at Samsung.com. It joins the other S9 flat UHD 4K models which are available in 85- and 110-Inch screens. The UN105S9W is a full array LED backlit LCD with local dimming using Samsung’s propriety UHD dimming and Precision Black technology.

Due to its wider aspect ratio the native screen resolution is 5120 x 2160 making the UN105S9W the highest resolution TV (with over 11 million pixels) available.

The UN105S9W comes with the floor stand, however the LCD panel can be detached and mounted to a specialty wall mount (price and model number TBA).

Each 105inch TV will be made to order.

LG’s Swarovski-encrusted OLED TV

There are few things that scream class more loudly than coating a piece of consumer electronics in gold. Except, perhaps, for doing the same thing, but with Swarovski crystals. That’s the truth-bomb that LG has just deposited into our laps, having announced it’s bringing an OLED HDTV with such glittery detailing here at IFA. Why? We can’t even begin to answer that question, but LG claims the 460-crystal pattern “turns a cutting-edge television into a work of art.” There’s no word on a price, but LG says this TV will go on sale in Europe this year — we’d rather forego the crystals to get OLED down to a price that competes with the best LCDs and Ultra HD TVs instead.

Samsung UHD TV to Get Amazon Streaming & Video Pack

Samsung has just struck a deal with Amazon and several other partners to expand its ultra high-definition (UHD) content offerings. The partnerships will give Samsung TVs access to new services including live 4K broadcasting, video-on-demand (VoD) and a long-awaited UHD video pack (at least in the UK and Europe).

4K TV, also known as Ultra-High Definition television, provides a whopping 3,840×2160 pixel resolution – four times regular Full HD. But as good as it looks, the vast majority of 4K TVs are more expensive than 1080p HDTVs, and there’s a real scarcity of native content that makes it hard to justify shelling out for one.

That conundrum means it’s in the interests of TV manufacturers to do everything they can to ensure their customers get more Ultra HD content to watch, and that’s exactly why Samsung is embracing Amazon. From October, Samsung’s UHD TVs will be able to stream content (both movies and TV shows) directly from Amazon’s on-demand video streaming service. Samsung says the service will be available “globally”, although we wouldn’t be surprised to see some countries excluded from the deal.

Amazon’s 4K Ultra HD VoD service, called Prime Instant Video, is scheduled to launch this October, and will compete with the likes of Netflix, which already offers 4K streaming, and DirecTV, which plans to stream 4K content on-demand later this year. For now it appears as though Amazon’s service will be exclusive to Samsung – although Amazon probably won’t be able to resist the temptation of selling its service to other brands once it’s up and running.

Besides Amazon, Samsung is also teaming up with content providers including Chili, Maxdome and Wuaki.tv., to provide even more 4K content. The company gave scant details of these partnerships so we can’t say for sure what countries these services will be offered too.

Finally, the Korean firm says it will show off its long-awaited “UHD video pack” at next month’s IFA show in Berlin. The video pack, which has been produced in association with Fox Home Entertainment and consists of no less than forty 4K movies including Life Of Pi and Star Trek: Into Darkness preloaded on a 500GB media player, was first teased at last January’s CES show in Las Vegas and subsequently released in the USA, but was delayed in the United Kingdom and Europe due to licensing issues. We assume that those problems have now been resolved, and that Samsung UHDTV owners on these shores can look forward to more native 4K content.
