About This Item

 

Full Description

This 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, it specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records, 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 (hereafter referred to as the 525/60 system) and the 625-line system with a frame frequency of 25 Hz (hereafter referred to as the 625/50 system).

Intraframe bit-rate reduction is applied to video data prior to recording.
