Abstract

PURPOSE: To simplify the constitution and transmit pictures without intermission by providing at least two buffer memories that keep the capacity of one block and using at least one of them for picture transmission.
CONSTITUTION: The input video signal Vin is converted to 8-bit PCM signal 12, 4-bit parallel signal 13 and 36-bit parallel signal 14 and passes through the changeover switch 15 and fed into frame memory 16. Address counter AR17 of memory 16 starts functioning at the clock frequency of magnetic disk 26 at the instant the signal of one frame is written completely (speed of video signal until this time), reads out the signal of memory 16, converts it to the series data 20 and writes into disk 26. During this time, the contents of frame memory 18 are continuously read out at the speed of video signal, converted to a 4-bit parallel data 21, passes through changeover switch 22, converted to an 8-bit parallel data 23 and, then, analogous picture output signal Vout is obtained by D/A converter 24 (no intermission while the contents of memory 16 are being stored).
