What is this BS EN 61834-7 - Helical-scan digital video cassette recording system about?
BS EN 61834-7 discusses recording and helical-scan digital video cassette recording systems using 6,35 mm magnetic tape for consumer use (525-60, 625-50, 1125-60, and 1250-50 systems) with a focus on DTV format. BS EN 61834-7 is the seventh part of the BS EN 61834 multi-series on the recording that is an extension to the SD specification (SD mode) and covers the features necessary for the recording and reproduction of EDTV2 signals.
While all DVCRs must have the capability of recording and/or playback in SD (SP) mode, this extension is optional. BS EN 61834-7, the data track structure of a track is defined by APT = 000b which consists of four areas as described in IEC 61834-1, and AP1 = AP2 = AP3 = 000b.
Who is BS EN 61834-7 - Helical-scan digital video cassette recording system for?
BS EN 61834-7 on helical-scan digital video cassette recording system is useful for:
- Video cassettes recording system manufactures
- DVCRs manufacturers
- Recording studios
Why should you use BS EN 61834-7 - Helical-scan digital video cassette recording system?
Video signals are initially sampled at 13,5 MHz for luminance and 6,75 MHz for colour differences. The video signal is also input and output digitally in a bit-serial form. When the bit-serial interface for this standard is prepared, the data structure for transmission is conform.
BS EN 61834-7 discusses helical recordings, programme track data arrangement, audio interface, video interface, audio signal processing, and video signal processing.
BS EN 61834-7 will help understand the features necessary for the recording and reproduction of EDTV2 signal.
