PURPOSE:To attain the processing where interception is difficult and sound quality including a reproduced video image is excellent by applying delta modulation to the sound, transmitting a reference value at each predetermined time and attaining initializing. CONSTITUTION:The output of a buffer 8 is sliced by a slice circuit 12 after synchronism reproduction, shaped into a binary signal, sampled by a sampling circuit 13 and a sound data is stored to a buffer memory 18, the signal subject to delta modulation is demodulated by a delta demodulator 19, the result is transferred to a buffer memory 20, the output of the buffer memory 20 is DA- converted by a DA converter 21 and the sound with high quality is outputted from left and right speakers. |
