BS EN 62071-3 discusses a helical-scan compressed digital video cassette system using 6,35 mm magnetic tape and format D-7 with a focus on data stream format.
BS EN 62071-3 is the third part of the BS EN 62071 multi-series on helical-scan compressed digital video cassette system that defines the format of the data stream for the synchronous exchange of DV-based audio, data, and compressed video (whose data structure is defined in SMPTE 314M) over the interface defined in SMPTE 305M.
BS EN 62071-3 covers the transmission of audio, subcode data, and compressed video packets associated with DV-based 25 and 50 Mb/s data structures including faster-than-real-time transmission for 525/60 SDTI and 625/50 SDTI systems.
Note: BS EN 62071-3 does not include the data stream of a DV-compressed structure as defined in SMPTE 322M.
BS EN 62071-3 on helical-scan compressed digital video cassette system is useful for:
Space within SMPTE 305M not used by a data stream conforming to BS EN 62071-3 are used for the transmission of data other than those representing DV-based audio, data, and compressed video. BS EN 62071-3, the 60 Hz system refers to the field frequency 59,94 Hz system and the 50 Hz system refers to the field frequency 50,0 Hz system.
BS EN 62071-3 discusses identification within the serial data transport interface (SDTI), stream block format, reserved data words, signal type words, transmission type word, DIF block ID words, DIF block data words, error correction code (ECC) words, transmission order, and mapping structure. This will help you with the format of the data stream for the synchronous exchange of DV-based audio, data, and compressed video on the helical scan digital video.
