ST 399:2004 - SMPTE Standard - For Digital Television Recording — 1/2-in Type D-15 High-Definition Compressed Video Data Format

This standard specifies the content, format, and recording method of the data blocks containing compressed video data, AES3 audio data, and associated data which form the helical records on 12.65-mm (0.5-in) tape. In addition, this standard specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records, and also the longitudinal cue audio, and time and control code. — One video channel of high definition compressed video data and eight independent AES3 audio data channels are recorded in the digital format. Each of these channels is designed to be capable of independent editing. — The HD video compressed data are derived from the following HD video signals: – 1080 line / 59.94 Hz field frequency interlace system (1080/59.94i) –720 line / 59.94 Hz frame frequency progressive system (720/59.94p) – 1080 line / 50 Hz field frequency interlace system (1080/50i) – 1080 line / 25 Hz frame frequency progressive system (1080/25p) – 1080 line / 24 Hz frame frequency progressive system (1080/24p) – 1080 line / 23.98 Hz frame frequency progressive system (1080/23.98p) — Through out the text of this standard, the expression “AES3 audio data” may be abbreviated to “audio data” and represents digitized audio and data in AES-3 format. The tape format also supports a recording of AES-3 data payload streams with some limitation (see 6.3.3 d).
