Abstract
PURPOSE:To prevent a data omission and to obtain a stable time axis fluctuation correction by giving a time difference between the reading reset pulse of a chrominance signal and the reading reset pulse of a luminance signal. CONSTITUTION:In a recording mode, an output obtained from a crystal voltage control oscillator 77 is made into a clock, it is used for the writing and reading of a first and a second memories 71 and 72 and the time difference is given to the pulses for the writing reset and for the reading reset to the first memory 71. On the other hand, in a reproducing mode, the output of the crystal voltage controller oscillator 77 is used as a reading dedicated clock to the first and the second memories 71 and 72 and the output of a voltage control oscillator 75 is used as a writing dedicated clock to the first and the second memories 71 and 72. Thus, an exact and stable signal processing can be executed.
