摘要： In the chroma killer detection for detecting the abnormality of the burst signal, in addition to the circuits (1004, 1005, 1006) for detecting the states of the components of the burst signal, which circuits are for selecting the cosθ data of the burst signal, circuits (1050, 1051, 1052) for detecting the states of the R-Y components, which circuits are for selecting sinθ data are employed for chroma killer detection. Thereby, it is possible to enhance the detection precision of the abnormality states of the burst signal and the precision for discrimination of the broadcasting system.
