Abstract
When the input output controller 22 receives request data through the modem 42, the input output controller 22 controls the memory controller 25 to retrieve an AV stream and a BGV stream from the memories and to transfer the streams to the multiplexer 30. The memory controller 25 retrieves a BGV stream from the BGV memories 26a, 26b, and 26c and an AV stream from the AV memories 27a, 27b, and 27c. When receiving the BGV stream and the AV stream, the multiplexer 30 divides the AV stream into a lyric stream and a music stream. The multiplexer 30 composes the lyric stream and the BGV stream into a video stream. The multiplexer 30 time-divisionally multiplexes the video stream and the music stream and outputs the multiplexed stream as a video/music stream.
