适用范围:This part of IEC 62071 defines the DV-based data structure for the interface of digital audio, subcode data and compressed video with the following parameters:
525/60 system - 4:1:1 image sampling structure, 25 Mb/s data rate;
525/60 system - 4:2:2 image sampling structure, 50 Mb/s data rate;
625/50 system - 4:1:1 image sampling structure, 25 Mb/s data rate;
625/50 system - 4:2:2 image sampling structure, 50 Mb/s data rate.
This standard does not define the DV compliant data structure for interface, of digital audio, subcode data and compressed video with the following parameters:
625/50 system - 4:2:0 image sampling structure, 25 Mb/s data rate
The compression algorithm and the DIF structure conform to the DV data structure as defined in IEC 61834. Differences between the DV-based data structure defined in this standard and IEC 61834 are shown in Annex A.
