Patent ID: 7239801

Claim:
A recording apparatus for recording an audio signal and a video signal on an information recording medium, comprising: separation means for separating a transport stream in which a compressed and coded video signal and a compressed and coded audio signal are multiplexed into a video elementary stream and an audio elementary stream; video packetized elementary stream packet generating means for generating video packetized elementary stream packets by dividing the video elementary stream in which a video signal is compressed and coded according to a predetermined method one video frame and by adding a header; audio packetized elementary stream packet generating means for generating audio packetized elementary stream packets by dividing the audio elementary stream in which an audio signal is compressed and coded according to a predetermined method by one audio frame and by adding a header; video packetized elementary stream packet unit generating means for generating a video packetized elementary stream packet unit by combining the three video packetized elementary stream packets; audio packetized elementary stream packet unit generating means for generating an audio packetized elementary stream packet unit by combining the audio packetized elementary stream packets corresponding to the video packetized elementary stream packet unit; sync block generating means for generating sync blocks by alternately disposing the video packetized elementary stream packet unit and the audio packetized elementary stream packet unit and by converting the video packetized elementary stream packet unit and the audio packetized elementary stream packet unit into a predetermined recording format; and recording means for recording the sync blocks on said information recording medium, wherein each video packetized elementary stream packet unit includes three frames, an I picture, a B picture, and a B picture, or a P picture, a B picture, and a B picture.
