PURPOSE:To increase a common use part of a PCM processing system, and to allow a titled device correspond to plural video signal types by minimum switching, by constituting a data block for correcting an error of a digital data, of 10 data. CONSTITUTION:Signals of 2 channels which are inputted alternately from an input terminal 1 are quantized by an A/D converter 3, are divided into suitable data blocks, and are sent to an interleaving storage RAM5 or 6 through a correcting code generating circuit 4 and switches 12, 13. At every block, in succession to data, an output of the correcting code generating circuit 4 is sent to the RAM5 or 6. The data starts synchronously by a vertical synchronizing signal, the data is counted by each 10 data by a counter 21 for counting in a sampling period, and is made to a data block and is sent to the switch 13. Simultaneously, it is transferred to the correcting code generating circuit 4. |
