ABSTRACT:
A video signal reproducing system has a video memory for storing a video signal fed from a source, a memory controller for controlling production of a video signal stored in the video memory, and a display for reproducing a video signal produced from the video memory. Level of an audio signal applied to the display is detected. A detected level is compared with a reference value. A change signal is produced when the detected level is higher than the reference value. In response to the change signal, a video signal stored in the video memory is produced for the reproduction thereof.
