PURPOSE: To perform excellent signal processing without malfunction, even if the transfer rate of input and output data is different, by alternate write-in and readout operations of two systems of memories.
CONSTITUTION: Since the write-in of an input data 1 to a memory 29 can be made from around the start of the next horizontal synchronizing period with synchronized state to the output data master block via auxiliary memories 8, 9, even if the length of the horizontal synchronizing section is reduced because of missing of signals and skew, the signal processing can be made with sufficient time margin. This, the transfer route of the input data 1 and output data can arbitrarily be set and the processing as to correction can be made in synchronizing with the output data master block, allowing to reduce the production of malfunction even with variation in the transfer route of the input data 1.
