Abstract: Serial digital interconnect (SDI) for video, defined by SMPTE 259M, is rapidly becoming the implementation method of choice for new and expanding television installations. One of the advantages of SDI is its ability to carry a significant amount of ancillary data: approximately 9 Mbits/sec for composite signals and 50 Mbits/sec for component signals. Although the available ancillary data space has been defined by standards for some time, the specifications for its use are more recent and continuing developments. The first applications of ancillary data were 20 bit/sample embedded digital audio (defined in SMPTE 259M) and video signal error detection (defined in SMPTE RP165). SMPTE 272M, published in the April 1994 issue of the SMPTE Journal, provides a full definition of embedding digital audio in the serial digital video data stream. This paper describes the available ancillary data space for the various signal formats and provides a detailed explanation of the rules for embedding digital audio into SDI.
