Xilinx Inc. and MBITL, an R&D subsidiary of Screen Service Broadcasting Technologies S.p.A. have demonstrated a jointly developed reference design for video-over-IP and IPTV at IBC 2007.

The cost effective reference design, based on Xilinx Virtex-5 and Spartan-3 FPGAs, is aimed at video-based solutions including broadcast, video conferencing, CCTV, surveillance, wired and wireless IPTV applications.

The collaborative demonstration offered an end-to-end broadcast chain from image capture to transmission using DVB-T and DVB-H modulation schemes originating in SSBT's MAGNUM transmitter, a software defined transmitter enabled by Xilinx Virtex-5 FPGAs. The transmitter is capable of loading different modulation schemes, thus allowing smooth transfer from analog to digital broadcasting or easy migration from one digital standard to another. The MAGNUM series is the latest generation of high-integration digital television transmitters for SFN and MFN networks.

The reference design supports multiple channels in and out, bridging between DVB-ASI and Ethernet IP packets, and forward error correction (FEC) using the ProMPEG Code of Practice 3 (CoP3) and the ProMPEG Code of Practice 4 (CoP4)for compressed transport streams and uncompressed SDI video sources. Additional flexibility is provided through a choice of memory and processor configurations to closely match technical requirements.

"The joint reference design development with MBITL provides very important building blocks for transmitting broadcast quality A/V data across IP networks," said Paolo Masini, senior manager of broadcast vertical marketing, Xilinx. "Through this collaborative effort, Xilinx can now provide a high-performance, optimized video-over-IP FPGA solution, allowing broadcast equipment providers to implement IP-capable ports in their equipment with faster time-to-market."

Production versions of the video over IP reference design, including associated application notes, will be available free of charge in Q4.
