Xilinx Inc. and Vanguard Software Solutions Inc. (VSofts) demonstrate VSofts' H.264/AVC-I IP core at the IBC2010 conference. VSofts' H.264/AVC-I IP core displayed the ability to deliver a low latency, ITU (International Telecommunication Union) and Panasonic AVC-Intra compliant Field Programmable Gate Array (FPGA) implementation of the industry-standard codec for providing minimal delay from source to encoded video in real-time video broadcast applications.

"The technology of video capture and broadcast is moving very rapidly," said Felix Nemirovsky, VSofts' VP of Marketing. "When it comes to high value content acquisition, editing and archiving, the flexibility and high data rate, real-time performance offered by basing our AVC I-frames encoder on Xilinx's proven and market-leading FPGAs allows us to meet the demands of a rapidly evolving marketplace."

As the demands of video capture and display move towards 3D TV and 4Kx2K Digital Cinema, FPGAs give designers flexibility during the design cycle and into production as standards evolve, while providing the levels of performance required for driving real-time video. Each evolution from 1080i through 4Kx2K formats requires an 8x increase of throughput off the back of the camera from 1.5Gbit/s to 12Gbit/s. This creates a potential chokepoint at each stage of the broadcast chain from camera, to contribution encoders passing video from professional studios, to video servers and to post-production houses.

The H.264AVC Intra IP core relies on the inherent flexibility, parallel processing and high-speed connectivity capabilities of Xilinx's Virtex-6 FPGA to overcome these chokepoints by significantly reducing the encoding delay from camera acquisition through to live broadcast.

"The broadcast industry's evolution is moving faster than custom or standard off-the-shelf system-on-chip solutions can support in terms of performance, flexibility and time-to-market," said Dean Westman, VP, Communications Business at Xilinx. "VSofts' H.264AVC Intra encoding solutions underscores the value of IP in Xilinx's Targeted Design Platform approach for meeting the performance and development needs of broadcast equipment developers."
