ST 371:2002 - SMPTE Standard - For Television — 6.35-mm Type D-12 Component Format — Digital Recording at 100 Mb/s 1080/60i, 1080/50i, 720/60p

This 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 307M. — In addition, this standard specifies the content, format, and recording method for longitudinal cue and control tracks. — One compressed video channel, eight independent audio channels and sub-code data are recorded on tape in the digital form. Each of these channels is capable of independent editing. — The helical recordings are synchronized to on the following digital video formats: – 1080-line/59.94-Hz field frequency – 1080-line/50-Hz field frequency – 720-line/59.94-Hz frame frequency — These are hereafter referred to as the 1080/60i, 1080/50i, and 720/60p systems, respectively. Similarly, in this document, the 60-Hz system nomenclature refers to both 1080/60i and 720/60p systems; whereas, the 50-Hz system refers only to the 1080/50i system. Nomenclature 1080-line system refers to both 1080/60i and 1080/50i systems, while, the 720-line system refers only to the 720/60p system. — The recorded digital video signal shall be compressed according to the DV-based 100-Mb/s specification. The recorded digital video signal, eight audio channels, and sub-code data shall be defined by the data structure according to the DV-based 100-Mb/s specification.
