Claims (1)

[Scope of utility model registration request] A television receiver in which the video signal processing circuit portion is digitized, and a digital/digital receiver that converts the digital luminance signal and the digital color difference signal output from the video signal processing circuit into analog signals at different sampling frequencies. A converter, and the luminance signal and color difference signal converted into the analog signals are input, and the R. G. RG that outputs B3 primary color signals
B matrix circuit, and the R.B matrix circuit; G. In a television receiver having a picture tube drive circuit to which a B3 primary color signal is introduced, at the input stage of the picture tube drive circuit, an R. G. A television receiver characterized in that a filter capacitor is inserted between B3 primary color signals.
