ABSTRACT:
A reproduction speed conversion apparatus includes an audio decoding section; an audio reproduction speed conversion section; a video reproduction speed conversion section; and a video decoding section. The video reproduction speed conversion section determines whether reproduction speed conversion corresponding to a requested level is possible or not. When the reproduction speed conversion is determined to be possible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to the requested level. When the reproduction speed conversion corresponding to the requested level is determined to be impossible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to a prescribed level lower than the requested level, and outputs a second reproduction speed signal representing the prescribed level to the audio reproduction speed conversion section. The audio reproduction speed conversion section performs reproduction speed conversion corresponding to the prescribed level in response to the second reproduction speed signal.
