IPC: H04N9/84
Filed: 1986-02-06
Abstract: PURPOSE:To decrease unnecessary radiation and power consumption by providing a comb-line filter using a delay circuit, a means to detect the time base variation of a chroma signal, and a means to control the frequency of a clock pulse, and preventing the delay of APC action from occurring. CONSTITUTION:A CCD is used for the one H delay circuit 8. The comb-line filter 9 to eliminate a cross talk constituted by the circuit 8 and a subtractor 5 is disposed in a stage preceding to a frequency converting circuit 2. A reduced chroma signal C1 is supplied to the filter 9 via an ACC circuit 1. Since the signal C1 includes jitters, if the delay time of the circuit 8 is constant, the timing shifts because of the jitters. Therefore, the elimination of a cross-talk goes to be impossible. So, the pilot signal P of a specific frequency nfH is generated and inserted in the signal C1, and the amount of jitters is detected based on the signal P. The delay time of the circuit 8 is controlled in accordance with said amount.
