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 processes required to decode the DV-based data structure into eight channels of AES-3 digital audio at 48 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 system Input video format: 1920 1080 image sampling structure, 59,94 Hz field rate, interlace format. Compressed video data rate: 100 Mb/s 1080/50i system Input video format: 1920 1080 image sampling structure, 50 Hz field rate, interlace format. Compressed video data rate: 100 Mb/s 720/60p system Input video format: 1280 720 image sampling structure, 59,94 Hz frame rate, progressive format. Compressed video data rate: 100 Mb/s In 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-line system refers to both 1080/60i and 1080/50i systems, while the 720-line system refers only to the 720/60p system.
