System and method for removing noise when switching between heads in a digital video cassette recorder

摘要

Audio playback system and method for a Hi-Fi VCR capable of preventing an occurrence of noise when audio heads are switched. When an azimuth occurs with respect to each arrangement angle of audio heads or when one of audio signals played back audio heads is delayed due to the elasticity of VCR tape, a correction signal generator detects a phase difference between the audio signals and corrects error in the audio signals according to the detected phase difference. By switching units, error corrected audio signals are switched and combined into continuous audio signals, each corresponding to a stereo channel. As a result, it is possible to avoid an occurrence of noise at a portion at which audio signals of the same stereo channel are connected.
