Xilinx provides vast resources for implementation of standard serial digital video and audio interfaces. On this page you'll find information and links to application notes (including reference designs) and hardware platforms to enable you to verify the performance of our solutions and to easily integrate these interfaces into your own systems. And don't forget Xilinx has a vast array of solutions for more generic connectivity requirements from backplanes to telecom. |
SDI & HD-SDI -
(High Definition) Serial Digital Interface
SDI (SMPTE 259M) and HD-SDI (SMPTE 292M) are widely used in broadcast studios and video production centers to transport digital video serially over coax cable. Implementation of multiple channels of SDI and HD-SDI are possible in Xilinx FPGAs and typically result in substantial cost savings versus ASSP-based solutions. Support of multi-rate designs incoporating SD and HD SDI as well as DVB-ASI mean that the FPGA becomes an extremely flexible, cost-effective connectivity solution . With superb jitter performance/tolerance and excellent signal integrity, Xilinx FPGA solutions are also very robust and reliable in high noise environments.

DVB-ASI - Digital Video
Broadcast- Asynchronous Serial Interface
DVB-ASI is a serial video communications standard defined by the DVB consortium for use in transporting MPEG-2 encoded video streams. The standard is most commonly used to connect cable head-end equipment that transports MPEG-2 streams. Data is transported at a rate of 270 Mb/s. A complete discussion of DVB-ASI specifications is provided in EN 50083-9: Cabled Distribution Systems for Television, Sound and Interactive Multimedia Signals, available from ETSI. Implementation of multiple channels of DVB-ASI are possible in Xilinx FPGAs and typically result in substantial cost savings versus ASSP-based solutions. When integrated with SDI and HD-SDI, the FPGA becomes a true connectivy platform for all kinds of applications handling compressed and uncompressed video.

To provide a convenient video source within
the FPGA, Xilinx has provided two test pattern generators.
These support the popular SMPTE EG 1 test pattern for SD,
and SMPTE recommended practice RP 219-2002 test pattern for
SD and HD.

AES/EBU (Audio Engineering Society/European Broadcasting Union), also known as AES3, is a standard for carrying digital audio signals between various devices. The consumer version of AES/EBU is S/PDIF (Sony/Philips Digital InterFace). The audio data between AES/EBU and S/PDIF is the same, but there are some connector and protocol differences. I2S (Inter-IC Sound) is an internal digital audio interface found mainly in consumer electronics devices like CD/DVD players and TVs. Including audio connectivity on Xilinx FPGAs means further cost savings versus ASSP-based approaches, particularly when part of a larger video processing system which alreasy uses FPGAs. The added flexibility of supporting multiple audio channels alongside video means that Xilinx can provide a scalable, high-performance platform for your application which reduces space requirements and the related PCB real estate and power management costs.
