A compressively coded data reproduction apparatus and method for separating compressively coded video, audio, and additional data, data from a stream, outputting these data performing head detection on video and audio frames; decoding the video frames to output video data; decoding the audio frames to output audio data; judging whether a detected head frame is a video frame or an audio frame corresponding to a designated entry point start time information being among the additional data of the detected frame, outputting a decoding request when the detected frame is judged as a video and/or audio frame corresponding to the start time, and outputting an output request at the point of time when both of the video frame and the audio frame have been decoded. The system can output a video frame and an audio frame at the same time, within a prediction of video frame unit or audio frame unit, when starting reproduction of compressively coded data from an entry point.
