20、TE SYSTEM USING 6,35 mm MAGNETIC TAPE FORMAT D-7 Part 3: Data stream format 1 Scope 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 SM
21、PTE 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 str
22、ucture 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 s
23、ystem and the 50 Hz system refers to the field frequency 50,0 Hz system. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the reference
