Recorder of pcm sound signal
专利汇可以提供Recorder of pcm sound signal专利检索，专利查询，专利分析的服务。并且PURPOSE:To detect assuredly a burst error by detecting the state of a specific bit that has no change of the bit contents in a normal state among additional codes of the PCM sound signal data for the satellite television broadcast. CONSTITUTION:The digital signal sent from a demodulating circuit is supplied to an error correcting circuit 231 of a decoder 23 as well as to an extracting circuit 234 of sound control bit, i.e., a specific bit in the control code. The data undergone the correction of errors through the circuit 231 undergoes the error correction again through an error correcting circuit 232 and fed to a shift register 233. The sound control bit extracted by the circuit 234 is supplied to a majority decision circuit 235. When a burst type error is generated, 0 and 1 are stored at random to the circuit 235. A detecting circuit 237 shifts the data stored in the register toward the lower order side 233 in case the number of error bits exceeds a prescribed level. Thus the output level of the register 233 is lowered.，下面是Recorder of pcm sound signal专利的具体信息内容。
