AV.link

Abstract: In a system having many apparatus connected with AV link (5,6), e.g. using SCART connectors (1-4), automation of configuration can be realized. A transmission side apparatus varies a signal which is sent to pin-8 with interpolation of a certain time period from a signal which is sent to pin-10. The signal of pin-8 is different from the signal of pin-10 in that the signal is insulated between connectors in an apparatus and operates independently for each connection. Therefore the receiving side apparatus can identify the physical position of the transmission side apparatus with reference to pin-8 signal and can discriminate the type of the transmission side apparatus with reference to pin-10 signal.
