Abstract
A processor for analog and digital audio, video, and control information has analog connections to supply analog A/V signals and output control information to a television set. At the beginning of a recording mode in the DVHS video recorder, when an A/V signal (which may be a processed digital reception signal) of a television program just being displayed on the television set is applied to the television set, the signal is supplied to the DVHS video recorder as an A/V signal via an analog connection and/or as digital A/V data via a digital connection. An A/V signal of a television program being displayed on the television set and supplied by its tuner is transferred from one analog connection to another analog connection from the beginning of a recording mode in the DVHS video recorder, as a result of which the A/V signal is recorded by the DVHS video recorder.
