PURPOSE:To display text quickly after specifying a piece of music by separating a reproduced signal into an accompaniment music signal, a program signal, a word data, and a timing signal in accordance with discrimination codes to process these signals. CONSTITUTION:A digital audio disc DAD2 in which various signals have been already recorded is set up on a DAD reproducing device 1 and reproducing is driven. In the device 1, an optical reading system part 5 reproduces a signal and a decoding system part 7 separates the reproduced signal into an accompaniment music signal 8, a program signal, a timing signal 9, and a contol signal 10 on the basis of the dscriminatuon codes and outputs these reproduced signals. The control signal 10 is inputted to a reproducing device controlling part 12 to execute focus, feeding and tracking control to the optical reading system part 5 and control also the speed of a motor 13. Prior to the reproducing of the accompaniment music signal 8, the program signal on the DAD2 is reproduced and the output signal 9 is displayed as text corresponding to the accompaniment music on the video displaying surface of a TV receiver 15 on the basis of the control by a small-sized computer 14. |
