SMPTE 321M-2002

This standard defines the format of the data stream for the synchronous exchange of DV-based audio, data, and compressed video (whose data structure is defined in SMPTE 314M) over the interface defined in SMPTE 305M (SDTI). It covers the transmission of audio, subcode data, and compressed video packets associated with DV-based 25 and 50 Mb/s data structure for 525/60 and 625/50 systems, including faster-than-real-time transmission.
