Abstract
An audio/video system provides communication control units on both a TV (television receiver) and a VCR (video cassette recorder) and includes an information path connected between both for executing data communications therebetween. When the VCR starts its 'play' operation, the system automatically turns the TV on and makes an inquiry regarding a connecting method between the TV and the VCR (i.e., whether the connection is an AV-connection or an RF-connection) for controlling the TV according to an input mode matched to the connecting method. When the VCR starts its 'record' operation while a user is currently watching the TV, the system turns the VCR on and then matches a channel number selected on a tuner built in the VCR to a channel selected on the TV.
