PURPOSE: To efficiently reproduce text information in the case of digitally compressing musical information by improving the recording density of the musical information for the text information. CONSTITUTION: In an audio compression part 10, the audio data on music, etc., digitally compressed based on e.g. an MPEG1 standard and the text data on a text, etc., corresponding to the music are multiplexed and corded on a compact disk 6, and when the recorded data are reproduced by an audio expansion part 20, the text data separated by a demutiplex circuit 12 are converted to a video signal for picture display by a display controller 16, and the text information is picture displayed, so that the text information corresponding to the music information is recorded or transmitted by the text data of an information amount less than the sound data or the image data, and the text information is efficiently reproduced or transmitted. |
