Abstract

PURPOSE:To remove a time base fluctuation at a sample point in a prescribed unit length by controlling the frequency of a clock related to the reading of a said prescribed unit length based on a time base error detected concerning a certain prescribed unit length. CONSTITUTION:For a reading clock clearing generating part 50, the frequency and phase of a reading clock pulse are controlled in accordance with errors te(n) and tq(n) related to an input TV signal read from an error correcting signal storing part 80 beforehand, before the sample point of the video period of the said scanning line is read from a main memory part 4. With the clock pulse to receive such a control, first, a sample string is read for respective scanning lines from the main memory part 4 and next, D/A-converted, and thereafter, a composite synchronizing signal is added in a process amplifier 6. Consequently, a TV signal, in which a time base error is corrected over all sample points, can be obtained at an output terminal 7.
