发明名称 VIDEO SIGNAL PROCESSING APPARATUS AND RE-SAMPLING APPARATUS
摘要 A video signal processing apparatus and a re-sampling apparatus are provided to suppress occurrence of false determination when extracting an auxiliary digital data signal by demodulating a composite video signal having the auxiliary digital data signal inserted therein into a component video signal. A video signal processing apparatus comprises a component video signal demodulator(12) and a re-sampling unit(13). The component video signal demodulator demodulates a component video signal sampled by a burst lock clock signal from a composite video signal sampled by the burst lock clock signal. The burst clock signal has multiplied frequency of a color subcarrier in the composite video signal having an auxiliary digital data signal inserted therein. The re-sampling unit converts sampling frequency of the component video signal selectively to a first frequency equal to or multiplied by horizontal synchronization frequency of the composite video signal or to a second frequency equal to or multiplied by frequency of the auxiliary digital data signal.
