Abstract
PURPOSE: To obtain a continuous and good picture excluding the omission of the picture by deciding whether a prescribed write period terminates or not according to a reproduced address, and controlling the switching timing of the write and the read of a memory.
CONSTITUTION: A field pulse 9 and an EOF pulse 16 are inputted to a read control circuit 3, and read enable signals RE1, RE2 are outputted. Then, when the signals RE1, RE2 are 'H' level, data 8 is read out from the address RA of field memories 1, 2, corresponding to these signals. Here, when the timing pulse 16 to show the termination of the field of the reproduced data is outputted, the signals RE1, RE2 are inverted at the next pulse 9 according to a decision based on these data, and the memory, to which the data 7 has been written till then, is switched to be read, and the memory, from which the data 8 has been read till then, is switched to be written. Besides, when the next field pulse is inputted before the pulse 16 is outputted, the circuit 3 is left as it keeps a former state, and the write and the read of the memory are not switched.
