This part of IEC 62447defines 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 370M) over the interface defined in SMPTE 305M. It covers the transmission of audio, subcode data and compressed video packets associated with DV-based 100 Mb/s data structures for 525/60 SDTI and 625/50 SDTI systems.
Space within SMPTE 305M not used by a data stream conforming to this standard may be used for the transmission of data other than those representing DV-based audio, data and compressed video.
In this standard, the 60 Hz system refers to the field-frequency 59,94 Hz system and the 50 Hz system refers to the field-frequency 50,0 Hz system.
