摘 要：
PURPOSE:To avoid deterioration in a time code signal and to surely obtain time information even when picture quality is adjusted in a soft level by devising the processor such that the frequency
characteristic of the time code signal is unchanged by the adjustment of picture quality. CONSTITUTION:The processor is provided with a 1st frequency characteristic adjustment circuit 9 adjusting a frequency of a composite signal superimposing a time code signal for a 1st prescribed period on a video signal and a 2nd frequency characteristic adjustment circuit 10 adjusting the
frequency characteristic of the composite signal. Then an output signal of the 1st frequency characteristic adjustment circuit 9 is selected for the 2nd prescribed period including the 1st prescribed period and an output signal of the 2nd frequency characteristic adjustment circuit 10 is selected for the 3rd prescribed period other than the 2nd prescribed period. Thus, the time code signal is not
