Why should you use BS EN 61834-11 - Helical-scan digital video cassette recording system?
BS EN 61834-11 describes the HD1 mode format extensions to IEC 61834-9 and IEC 61834-10. The 25 Mbps data rate mode shall be used for HD1 recordings. BS EN 61834-11 specifies the data structure for the HD2 mode for 1080i/60 and 1080i/50 systems. In the HD2 mode, the helical tracks contain an ITI sector, the main sector, and a subcode sector.
BS EN 61834-11 discusses the environment and test conditions, helical recordings, programme track data arrangement, HD1 mode for 480, 576, and 720 systems, seamless playback at the transition point, and HD2 mode for 1080 systems. This will help you with a method of data blocks containing video, audio, and system data on the helical scan digital video.
