| 1. An audio/video data recording/reproducing device, comprising:
a compressed data output part that outputs compressed data that has been recorded to an external device through a digital
interface;
a reproduction signal output part that outputs a synthesized signal after being subjected to compression, which is obtained
by expanding the compressed data that has been recorded to generate an audio/video signal, then further adding thereto another
audio/video signal to generate a combined signal, and subjecting the combined signal to compression to provide the synthesized
signal, to the external device through the digital interface;
a recording part that records the audio/video signal by compression; and
a switching part that switches between an output from the compressed data output part and an output from the reproduction
signal output part.
