PURPOSE:To obtain sound signals of error correction without a problem in listening, by performing the PCM demodulation from a PCM signal before one field period, when the signal is not suitable for the PCM demodulation only with error interpolation or correction. CONSTITUTION:When a signal Sp is written in a memory circuit 85M or 85N, error interpolation and correction are done based on the result of check of a CRC check circuit 81 with an error correction/interpolation circuit 86. In a control circuit 87, read signals Rm, Rn are formed and applied to a read terminal R of the memory circuits 85M, 85N. The signal Sp from the memory circuits 85M, 85N is applied to a switch circuit 83, a signal Rm is applied to the switch circuit 83 as a control signal and the signal Sp is picked up continuously. The signal Sp is applied to a D/A converter 84 and a sound signal Ss is demodulated and picked up at a terminal 76. |
