適用范圍：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 rateThe compression algorithm and the DIF structure conform to the DV data structure as definedin IEC 61834. Differences between the DV-based data structure defined in this standard andIEC 61834 are shown in Annex A.
