Abstract

PURPOSE:To stabilize a device and to decrease the cost, by extending a time axis through the use of useless time in a television signal and increasing the delay time in a loop. CONSTITUTION:An input video signal (a) is converted into a digital signal (b) at an A/D converter 1, and this is supplied to one line memories 2, 3. When the memory 2 is in write-in state and the memory 3 is in the readout state, write-in/readout signal j, i are in opposite state to each other, and write-in/readout clocks l, h are faster in write-in and slower in readout. Thus, a video signal (c) obtained through time axis conversion is forecast-coded in a clock (g) in slower frequency than the sampled clock used for the A/D conversion and quantized at a quantization device 4 to output a forecast coding signal (e).
