Reading circuit of subcode signal
专利汇可以提供Reading circuit of subcode signal专利检索，专利查询，专利分析的服务。并且PURPOSE: To perform efficiently the signal processing of a Q subcode by storing Q subcode data in a primary register, transferring the data to a secondary register when it is judged simultaneously that there is no data error in the Q subcode, and obtaining the correct Q subcode signal from the secondary register.
CONSTITUTION: A counter 4 for transfer writes the output data of a buffer register 2 in a corresponding address of the primary register 3 every time division data of one Q subcode are all set in a buffer register 2. A CRCC circuit 5, when it judges that there is no error in the Q subcode, reads 10 data stored in the primary register 3 and transfers and writes it in the secondary register 6. This data is read out successively under the command of a microcomputer 7 and converted by a parallel-serial converting circuit 9 into serial data, which is utilized to display the time on a display device 10, and retrieve the number of music specified on an input device 11.
