This International Standard specifies the content, format and recording method of the data blocks containing video, audio and associated data which form the helical records on 6,35 mm tape in cassettes, as specified in SMPTE 306M.
In addition, this standard specifies the content, format and recording method for longitudinal cue and control tracks.
One video channel and two independent audio channels are recorded in the digital format. Each of these channels is designed to be 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 525/60 system) and the 625-line system with a frame frequency of 25,00 Hz (hereinafter referred to as the 625/50 system).
Prior to recording, the digital video signal is compressed to a DV based 25 Mb/s bit stream, as specified in SMPTE 314M.
