適用范圍：This part of IEC 62071 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. It covers the transmission of audio, subcode data and compressed video packets associated with DV-based 25 and 50 Mb/s data structures including faster-than-real-time transmission for 525/60 SDTI and 625/50 SDTI systems.This standard does not include the data stream of a DV-compressed structure as defined in SMPTE 322M.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.
