BS EN 61179 discusses specifications for a helical-scan digital composite video cassette recording system using 19 mm magnetic tape with a focus on format D2 (NTSC, PAL, PAL-M).
BS EN 61179 specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records.
BS EN 61179 specifies the content, format, and recording method of the data blocks forming the helical records on the tape containing video, audio, and associated data using the 19 mm type D-2 cassette.
BS EN 61179 on the specification for helical-scan digital composite video cassette recording system is useful for:
A videocassette recorder, also spelt video cassette recorder (VCR), is an electromechanical device that records, stores, and plays back television programs on a television set by means of a cassette of magnetic tape.
The requirements given in BS EN 61179 relate to 525-line composite TV signals (NTSC, PAL-M) with a frame frequency of 29,97 Hz nominal, and to 625-line composite TV signals (PAL) with a frame frequency of 25 Hz.
BS EN 61179 define the electrical and mechanical characteristics of equipment which permits the interchangeability of 19 mm cassettes containing digitally recorded composite video programs. This will help you to understand the specification for the helical-scan digital composite video cassette recording system.
With obedience and compliance to BS EN 61179, you can enhance the helical-scan digital composite video cassette recording system’s effectiveness and efficacy and manufacture a standardized product.
