What is this BS EN 62330-3 - Helical-scan digital video cassette recording system about?
BS EN 62330-3 discusses a helical-scan digital video cassette recording system using 12,65 mm (0,5 in) magnetic tape and format HD-D5 with a focus on data stream format.
BS EN 62330-3 is the third part of the BS EN 61834 multi-series on the helical-scan digital video cassette recording that defines the data stream used for synchronous transmission of HD-D5 compressed video and audio data over 360 Mb/s serial digital interface (SDI) for the 525/60 system as defined in SMPTE 259M.
Note: BS EN 62330-3 practice does not define data stream structure applicable for transmission over the serial data transport interface (SDTI), SMPTE 305M.
Who is BS EN 62330-3 - Helical-scan digital video cassette recording system for?
BS EN 62330-3 on helical-scan digital video cassette recording system is useful for:
- Audio equipment manufactures
- Audio programmers
- Music producers
- Sound technicians
- Recording and dubbing studios
Why should you use BS EN 62330-3 - Helical-scan digital video cassette recording system?
HD-D5 compressed digital video data, assembled as a DIF block stream, are mapped onto an SDI video field for transmission.
BS EN 62330-3 discusses DIF block mapping, DIF block, and DIF slice, mapping of DIF blocks over SDI, audio Data, DIF slice structure, slice sell structure over SDI, DIF area type and byte allocation of DIF blocks, and bit allocation. This will help you with the data stream used for synchronous transmission of video, audio, and system data on the helical scan digital video.
