Abstract
A method for recording and reproducing video and accompanying audio information whereby various reproduction modes are made possible, including displaying a still image with appropriate sound, without adversely affecting the quality of the played-back signals. A video format signal, containing two-dimensional image information, is divided into a plurality of blocks. Audio information is inserted into predetermined ones of these blocks, and video information is inserted in the remaining blocks. The video format signal is recorded in this form on a magnetic medium. Upon reproduction, the blocks into which the audio information was inserted are, for video reproduction, either masked or replaced with other video information. Control information, including information correlating the audio and video information and, preferably, error correcting code information, is also recorded.
