Abstract

Defines the data structure for the interface of DV-based digital audio, subcode data, and compressed video at 100 Mb/s. It 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.
