適用范圍：This part of IEC 62247 defines the data structure for the interface of DV-based digital audio,subcode data, and compressed video at 100 Mb/s. This standard defines the processesrequired to decode the DV-based data structure into eight channels of AES-3 digital audio at48 kHz, subcode data, and high-definition video at 1080/60i, 1080/50i, and 720/60p.The following high-definition video parameters are used in this standard:1080/60i systemInput video format: 1920 × 1080 image sampling structure, 59,94 Hz field rate, interlaceformat. Compressed video data rate: 100 Mb/s1080/50i systemInput video format: 1920 × 1080 image sampling structure, 50 Hz field rate, interlace format.Compressed video data rate: 100 Mb/s720/60p systemInput video format: 1280 × 720 image sampling structure, 59,94 Hz frame rate, progressiveformat. Compressed video data rate: 100 Mb/sIn this standard, the 60 Hz system nomenclature refers to both 1080/60i and 720/60p systems;whereas the 50 Hz system refers only to the 1080/50i system. The nomenclature 1080-linesystem refers to both 1080/60i and 1080/50i systems, while the 720-line system refers only tothe 720/60p system.
