Abstract

PURPOSE:To decode an audio signal even with missing of a reproducing signal to be caused by recording the data while distributing an audio synchronizing block including prescribed the number of audio data and synchronizing data into the prescribed number of video synchronizing blocks. CONSTITUTION:The data including an audio synchronizing block is inputted to a terminal 101 and written in memories 104, 106 for each track. A switch 102 is switched by a timing signal given to a terminal 108. Then an address is designated by signals W1, W2 generated by address generators 103, 105 controlled by a timing signal for the write and the audio signal data is arranged scatteringly in the picture signal data. In reading the memory, a readout address is designated from the signals R1, R2 from the generators 103, 105. Thus, even if the reproducing signal is missing for a long time, the audio data can be decoded.
