Provides guidance on current practice for the characteristics of multimedia analogue interfaces to achieve interoperability between equipment from different manufacturers.

This International Standard gives guidance on current practice for the characteristics of multimedia analogue interfaces to achieve interoperability between equipment from different manufacturers. It is not a performance standard.

Recommendations for interfaces for equipment used in vehicles, and for analogue video interfaces for broadcast and similar equipment, are not given.

Refer to IEC 60958 for the interconnection of digital signals .

Figure 1 shows in a diagram the possible interfaces of the audio and video sources and destinations.
