Cloud-based video transcoding is here to stay and off the shelf cards will speed new technology to market, according to David Lin, senior director DSP & Video Solutions, Advantech and Atul Verma, business manager, Video Infrastructure, TI
It is an exciting time to be a technology provider in the video space. For a change, we are seeing market needs driving innovation and product roadmaps rather than technology trying to influence the market for the sake of coolness (remember 3D TV?). On the consumption side
people seem to have insatiable appetite for video, be it for entertainment or information, delivered to devices of their choice and at a time of their choosing. Google Chromecast flying off the shelves within hours of launch shows the extent of pent-up demand for video consumption. On the production side, it is
easier than ever to create and edit good quality content. Bridging the gap between production and consumption are technologies ranging from efficient workflow systems to transport and delivery – each of which is poised for product differentiation as video demand grows.
mean a sleek product design for consumer segment, on the infrastructure side it boils down to power, channel density, reliability and a number of other factors associated with platform efficiency. For some segments such as encoders, decoders and transcoders, differentiation is closely tied to programmability – vendors want the ability to put their value-add IP to augment core algorithms. In addition, infrastructure

remote newsgathering. As the technology matures and becomes more prevalent in endpoints, HEVC will find its way into standard broadcast, enabling some channels of Ultra-HD resolution or higher quality video delivery. While differentiation may
vendors want to be ready for tomorrow’s need – more video and resolutions of Ultra-HD and beyond. What they need is a platform that can scale easily without ripping out existing gear. The Keystone family of SOCs by Texas Instruments Inc. (TI) provides a programmable platform for realising video processing solutions that can scale easily for future needs. As video demand grows,
two related video infrastructure trends that started a few years
ago are gaining further steam. First, cloud-based video transcoding is here to stay due to the number of coding formats and resolutions that need to be supported on an ever-increasing number of devices. Second, the movement
towards employment of COTS cards for video processing is gaining traction due to fast time to market considerations – these cards can be used in standard server or custom chassis designs. Advantech’s DSP and Video Solutions Division is leading the charge with video processing cards and systems in a variety of form factors serving a number of market segments in addition to transcoding solutions. As you walk the IBC floors
you will see real world deployment of these cards in markets such as cloud gaming and remote desktop acceleration (CyWee) and high density mobile video streaming (Utelisys). 9.C22
STAR turn for localising radio commercials
International Datacasting Corporation By Ian McMurray
Making its first appearance in Europe at IBC is the second generation of the STAR system from International Datacasting Corporation (IDC). STAR provides radio networks with localised ad insertion, helping them to boost revenue and lower operating costs. Its ad and programme
insertion capability allows operators to send selected ads to specific regions, or receivers. Stored audio files can be inserted seamlessly into live or recorded programming. Cost savings can also be realised through shared hub support, which enables multiple radio networks to share one multichannel receiver instead of deploying several single-
channel receivers, says IDC. The STAR platform features time-shifting functionality, which allows broadcasters to play the right content at the ideal time. The developer claims that it also requires only a 120kHz space segment for a high quality stereo broadcast, as opposed to 400kHz for legacy systems, resulting in significant cost savings.
Also on display is IDC’s complete digital cinema content
distribution system. Featuring DVB-S2 technology for high- speed throughput and increased transmission reliability, IDC offers a variety of digital cinema solutions that are tailored to fit customer needs, including SuperFlex Pro Cinema receivers, cache servers and event players. IDC’s SuperFlex Pro Cinema Receivers form the basis of its digital cinema distribution system. The SuperFlex Receiver
can decode 3D video and includes Dolby 3D colour correction for digital cinema applications. It can also decode HD or SD video encoded with MPEG-2 and MPEG-4 AVC (H.264) with SDI, HD-SDI, HDMI outputs available. Over 70% of satellite- connected digital cinemas throughout the world use IDC’s Digital Cinema Solutions, according to the company. 1.C29
Experience HDR in the Future Zone goHDR By Adrian Pennington
Visitors to the Future Zone can pick up details of a free app that will allow them to watch a live High Dynamic Range video stream, courtesy of goHDR.
“We will also provide everyone with a show-reel of unique HDR video footage so they can explore and interact with the HDR content at their leisure,” explained Alan Chalmers, innovation director. “We invite you to see for yourself the step- change in viewing experience that HDR video is bringing.”
With mobile predicted to overtake fixed access of the internet by 2014, the ability to deliver high quality video content to mobile devices with significantly increased detail is likely to be a clear differentiator for media content providers. “goHDR’s solution preserves all the data from capture to
display,” said Chalmers. “On the display, including mobile devices, the user can see and interrogate information across the full spectrum of light levels. Different windows can be set allowing detail in different lighting conditions to be interrogated simultaneously, making HDR video more
powerful than the human eye.” This is achieved through a patented approach to realtime compression of light and colour information separately. Its new camera, developed at a cost of £10,000, uses two digital SLRs to create a single HDR video stream image containing around 20 f-stops at up to 30fps. 8.G49
