Abstract
PURPOSE: To compensate a dropout with high precision by applying a picture signal of the strongest correlation to a dropout position in reproduction, by storing picture signals and a dropout signal in a picture memory for one frame and dropout memory.
CONSTITUTION: Reproduced RF signal 1 is inputted to dropout detector 2 and demodulator 3. When signal 1 is below a level set value, detector 2 outputs dropout signal 4. Demodulator 3 demodulates signal 1 into picture signal 5. Since this signal 5 has variation in time axis, its time axis is stabilized by time-axis corrector 6 and the signal is sequentially stored in one-frame memory 7. On the other hand, signal 4 is so corrected by time-axis corrector 8 that its time axis will be in phase with signal 5, and it is sequentially stored in one-frame memory 9. Therefore, memory 9 is stored with dropout information of signal 5 stored in memory 7 at the same addresses.
