Abstract
To facilitate highly accurate editing with reference to the audio and to reduce the cost for facilitating highly accurate editing with reference to the audio, the following features are adopted: A slow-motion reproduction is enabled by reproducing video and audio signals recorded on a magnetic tape in a digital format at a speed lower than that of the normal reproduction and outputting a video signal of the same frame or field over a plurality of frame or field periods. An audio switching signal is generated in accordance with a variation in the video signal and the output of the audio signal is controlled in response to the audio switching signal, so that of the plurality of frame or field periods over which a video signal of the same frame or field is repetitively outputted, only during one frame or field period immediately after the video signal varies, the audio signal is outputted, and during the remaining frame or field periods, the output of the audio signal is stopped.
