What is this BS 7133 - Audio recording-PCM encoder/decoder system about?
BS 7133 discusses specifications for an audio recording-PCM encoder/decoder system to enhance the quality of the encoder/decoder system.
BS 7133 applies to the reversible process achieved by the PCM encoder/decoder system that transforms two audio signals into one PCM signal for compatibility with either the 60 fields/525 lines or the 50 fields/625 lines television system.
The PCM signal is retrieved from the video signal by the video cassette system and most of the occasional errors are corrected by using the redundant information. The decoder of the PCM encoder/decoder transforms the PCM signal into two audio signals.
Who is BS 7133 - Audio recording-PCM encoder/decoder system for?
BS 7133 on audio recording-PCM encoder/decoder system is useful for:
- Audio equipment manufactures
- Audio recording-PCM encoder/decoder system manufacturers
- Audio programmers
- Sound technicians
- Regulatory bodies
Why should you use BS 7133 - Audio recording-PCM encoder/decoder system?
The encoder of the PCM encoder/decoder transforms two audio signals into a PCM signal with redundant information added to correct occasional errors arising during recording or reproduction. The signal thus encoded is converted to a format that conforms to the relevant television system for recording onto a videocassette.
BS 7133 has been prepared to establish the signal format and other conditions required for the PCM encoder/decoder system that is intended for recording and reproducing audio signals in the form of a PCM signal through (part of) a domestic videocassette system.
BS 7133 helps to achieve standardized system operation, compatibility of encoder/decoder systems with players and systems, and interchangeability of recorded tapes.
With obedience and compliance to BS 7133, you can enhance audio recording-PCM encoder/decoder systems’ effectiveness and efficacy and manufacture a standardized product.
