What is BS EN 61603-7-Transmission systems for audio and/or video and related signals about?
BS EN 61603-7 discusses transmission systems for audio and/or video and related signals using infra-red radiation with a focus on digital audio signals for the conference and similar applications.
BS EN 61603-7 is the seventh part of the multi-series on transmission systems for audio and/or video and related signals that describes the characteristics of a digital multiple channel, multiple carrier audio transmission system as an extension to conference interpretation or similar systems using the frequency ranges 45 kHz to 1 MHz and 2 MHz to 6 MHz.
Who is BS EN 61603-7-Transmission systems for audio and/or video and related signals for?
BS EN 61603-7 on transmission systems for audio and/or video and related signals is useful for:
- Manufacturers of products that provide audio output (televisions, phones)
- Audio equipment manufactures
- Audio programmers
- Music producers
- Sound technicians
- Recording and dubbing studios
Why should you use BS EN 61603-7-Transmission systems for audio and/or video and related signals?
The scrambler consists of an XOR gate and a pseudo-random binary sequence (PRBS) generator. The length of the PRBS is 11 bits and is initialized after every frame sync. The system consists of a number (N) of audio sources, either analogue or digital, which are connected to a transmitter.
The transmitter processes the audio signals in accordance with the protocol described in BS EN 61603-7 into an electrical output to feed the infrared radiator. The infrared signal is received by the infrared receiver that processes the signal and outputs an audio signal and/or associated data.
With obedience and compliance to BS EN 61603-7, you can enhance the quality of audio and video signals and allow convenient storage, transmission, and retrieval of an audio and video signal.
