TELEVISION RECEIVER DEALING WITH DIGITAL BROADCASTING

摘要

PROBLEM TO BE SOLVED: To enable a display of OSD information without necessity of signal processing in a digital broadcasting receiver by a video signal input from an external video input terminal. SOLUTION: In a television receiver dealing with digital broadcasting, a digital broadcasting receiver circuit 110 generates a prescribed signal and processes to superimpose a received video signal with the generated prescribed signal when the prescribed signal is superimposed on the video signal received at a digital broadcasting receiving terminal 105 and displayed. Further, the circuit 110 generates the prescribed signal when the prescribed signal is superimposed on the video signal input from the external video signal input terminal 104 or selectively displayed. A video switching circuit 132 generates the prescribed signal and processes to select or superimpose the input signal with the prescribed signal generated by the circuit 132.
