30、 and control signals which use free radiation of infra-red (IR). Transmission using infra-red radiation is in growing use for many different applications. This standard gives guidance for the generic usage of infra-red. It provides information for designers and users of infra-red systems which allow
31、 the evaluation of the operation of different systems. IEC 764 specifies requirements for audio transmission with high quality audio transfer via two infra-red channels and for conference systems with up to nine audio channels and using frequency modulation on subcarrierc which amplitude modulate th
32、e IR intensity. However, this number of channels sets limits on technical evolution. The growing use of IR transmission, such as for remote control or data transmission, and the increasing number of cases, where modulated IR is emitted as a side-effect, reveals the need for a more general concept. I
33、nfra-red systems typically use radiation in the range of wavelengths from 830 nm to 950 nm. To take into account possible future development, this standard covers wavelengths from 700 nm to 1600 nm. A direct modulation of the frequency of the infra-red radiation is possible, but is not yet used for
34、transmission through air. It should not be excluded in the long term. - I The prevention of interference between different applications by the use of different - wavelengths is not yet economically feasible, but the situation may soon change; therefore this = possibility is allowed for in this stand
35、ard. - I - * v, * Most of the applications in the complete standard (six parts) already exist as wired systems. In extending to wireless links using infra-red, the aim is to retain the transmission properties of I the wired versions. This standard is therefore as consistent as possible with existing
36、 standards for wired systems. This standard gives guidance only on avoiding interference from light sources. For a fully compatible system, it is necessary to set limits both for the emission from light sources and for the immunity of the infra-red transmission systems. For ease of reference, the ap
37、plications covered in the different parts of this standard are explained in more detail in annex A.

38、cope This part of IEC 1603 gives methods of measuring and specifying the common technicai features of the parts of systems which use diffusely radiated or wide beams of infra-red radiation as carriers of information, mainly representing audio and/or video signals but also control data related to aud
39、io and video apparatus. This standard applies to signal transmission by use of freely radiated infra-red, normally used indoors in rooms and for groups of varying sizes. It does not cover security systems or other industrial applications, such as measurement and automation equipment. It also does no
40、t cover traffic systems or systems for the help of handicapped people. Narrow-beam and cable-like infra-red applications are excluded, although the former could interfere with the systems covered. 1.2 Normative references The following normative documents contain provisions which, through reference
