适用范围

Intraframe bit rate reduction is applied to video data prior to recording. This International Standard specifies the content, format and recording method of the data blocks containing video, audio, and associated data that form the helical records on 12,65 mm tape in cassettes. In addition, this standard specifies the content, format and recording method of the longitudinal record containing tracking information for the rotating head associated with the helical records, and also cue audio, and control tracks. One video channel and four independent audio channels are recorded in the digital format. Each of these channels is capable of independent editing. The video channel records and reproduces a component television signal in the 525 line system with a frame frequency of 29,97 Hz (hereinafter referred to as the “525/60 system”) and in the 625 line system with a frame frequency of 25,00 Hz (hereinafter referred to as the “625/50 system”).
