发明名称 COMPACT DISK SYSTEM WITH VIDEO SIGNAL AND ITS REPRODUCING SYSTEM
摘要 PURPOSE:To simultaneously reproduce a video signal at the reproduction of an audio signal by providing a moving image signal part with digital audio signal and a still picture signal part without audio signal on a video signal part in the inside of a disk. CONSTITUTION:In reproducing a moving image signal part 13 with the audio of a compact disk 14 with video signal, a signal read by a pickup 15 is given to an audio signal reproducing circuit 17 and a signal reproducing circuit 21, where an audio signal and a picture signal are reproduced respectively. In reproducing an audio signal part 10, the still picture signal part 12 without audio signal is reproduced at first and its picture signal is stored in the still picture memory 21. In reproducing the audio signal part 10, the picture signal of the still picture signal part 12 is read from the still picture memory 21 and outputted from a video signal output terminal 20. Moreover, a selecting means 22 is operated by a key switch group 24 to select optionally plural still picture signals stored in the still picture memory 21 and to output them from the video signal output terminal 20, as well.
