路。[Scope of claim for utility model registration]
a first color delay circuit that delays the first delayed color signal by a factor of n (where n is a natural number); and a second color delay circuit that delays the first delayed color signal by n times the color subcarrier period to generate a second delayed color signal. a second color delay circuit that delays the reproduced luminance signal by n times the color subcarrier period to generate a first delayed luminance signal; A second signal that generates a second delayed luminance signal with a delay of two times.
The luminance delay circuit selects the first delayed color signal before and after the rising portion of the reproduced luminance signal, selects the second delayed color signal during the first half of the rising portion, and selects the reproduced color signal during the latter half of the rising portion. A reproduction color signal waveform shaping circuit comprising a color switch means and a color switch means.
