BS EN 61834-6 discusses recording and helical-scan digital video cassette recording system using 6,35 mm magnetic tape for consumer use (525-60, 625-50, 1125-60 and 1250-50 systems) with a focus on SDL format.
BS EN 61834-6 is the sixth part of the multi-series on that describes the format extension, using higher compression to increase recording time and reduce running cost. While all DVCRs must have the capability of recording and/or playback in SD (SP) mode, this extension is optional.
BS EN 61834-6 on helical-scan digital video cassette recording system is useful for:
The audio signal is recorded in one audio block. The audio block is composed of five audio sectors in five consecutive tracks for the 525-60 system, or six audio sectors in six consecutive tracks for the 625-50 system. Audio samples and undefined values are shuffled over tracks and data-sync blocks within a frame.
BS EN 61834-6 provides one mode of encoding audio data within the audio block. The encoding parameters are defined. BS EN 61834-6 summarizes the specification for long play mode with high compression. BS EN 61834-6 specifies the applied specification of the definition of AUX position on digital interface in SDL mode.
