This Standard applies to the format for video cassette recording of digital component video signals and associated digital audio signals and related control signals, using the 12,65 mm magnetic tape. The video data are recorded using bit rate reduction. This standard specifies characteristics of the cassettes, the tape, the recording patterns on the tape, the processes of digital audio and video coding, data compression, error protection and channel coding which are the essential requirements for the interchangeability of the recordings.
