Transmission of audio and/or video and related signals using infra-red radiation - Part 3: Transmission systems for audio signals for conference and similar systems
This part of IEC 61603 gives methods for measuring and specifying those characteristics of audio infra-red (IR) transmission systems for conference and similar systems which are not covered by part 1 (see also 3.1). It allows systems which make different economic use of the available bandwidth to be described in order that conclusions regarding interference and compatibility can be drawn. Interface (matching) values and other system characteristics are also covered. The standard replaces chapter 2 of IEC 60764.
