ABSTRACT:
A recording/reproducing device has an NTSC decoder which receives a video signal and outputs a video signal, an MPEG audio encoder which receives an audio signal and outputs an audio signal, and a synchronous control circuit which detects a synchronizing signal from the video signal input to the NTSC decoder and uses that signal to generate an output synchronizing signal that is different from the input synchronizing signal. The output synchronizing signal is used to output the video signal from the NTSC decoder. In the recording/reproducing device, the NTSC decoder and the MPEG audio encoder provide a delay to the input video signal and audio signal, respectively, and output the video signal and audio signal in accordance with the output synchronizing signal generated by the synchronous control circuit.
