4 System consideration 4.1 Area of application This digital interface covers audio and/or video and accompanied data systems for consumer audio/video equipment and multimedia systems in bi-direction, mainly used for audio equipment, TV-set, D-VCR, etc. 4.2 Operating environment The environmental conditions for the digital interface are mainly defined in other standards for the individual units. Where no range is given, the interface shall operate at least within the temperature range 0 °C to 50 °C and in a relative humidity range of 25 % to 75 %. 5 Configuration of digital interface and characteristics to be specified 5.1 Configuration of digital interface The basic configuration of this digital interface is shown in Figure 1. The reference points 1 and 4 apply to the electrical input and output of the electro-optical and opto-electrical converter respectively. The optical matching values specified in this standard apply at the reference points 2 and 3. The overall characteristics of a POF are specified in Annex A for a wide-band POF and in Annex B for the optical connectors. NOTE Some applications based on this digital interface are illustrated in Annex C.
