What is this BS EN 62356-1 - Video recording about?
BS EN 62356-1 discusses video recording and 12,65 mm Type D-11 format with a focus on tape recording. BS EN 62356-1 is the first part of the BS EN 62356 multi-series on a video recording that specifies the format for the recording of Type D-11 compressed pictures, four channels of AES3 data, and associated data which form helical records on 12,65 mm tape in cassettes.
BS EN 62356-1 defines the helical track record parameters, the content, and format of the longitudinal records, and the cassette physical specifications. The recording format supports frame frequencies of 30/1,001 Hz, 25 Hz, 24 Hz, and 24/1,001 Hz.
Who is BS EN 62356-1 - Video recording for?
BS EN 62356-1 on video recording is useful for:
- Audio equipment manufactures
- Audio programmers
- Music producers
- Sound technicians
- Recording and dubbing studios
- Regulatory bodies
Why should you use BS EN 62356-1 - Video recording?
The rising edge of all control track pulses should be timed to coincide with the input (reference) video. The frame start point is defined as the midway point of the leading sync edge position that identifies the start of line 1 of the analog video signal represented by the input (reference) signal.
BS EN 62356-1 defines how input signal data streams comprising a Type D-11 picture compression data stream and four AES3 data streams are mapped to the helical track records. The burst data mode provides the capability to record 20-bit samples, which are time constrained to begin at a defined point after the source picture frame start and to finish at a defined point before the source picture frame end.
