Abstract:
1. A television receiver comprising: a tuner configured to receive a broadcast signal and to output a composite signal; a video decoder configured to convert the composite signal into a digital signal; a reproducer configured to reproduce data recorded on a DVD; a video encoder configured to convert each of the data and the digital signal into a Y/C signal; a detector configured to detect whether a signal level of the composite signal becomes lower than a threshold value while the broadcast signal is received by the tuner; a selector configured to selectively output either the composite signal or the Y/C signal; a monitor configured to display pictures based on one of the composite signal and the Y/C signal output from the selector; and a controller configured to cause the selector to output the Y/C signal when the detector detects that the signal level becomes no lower than the threshold value while the broadcast signal is received by the tuner, and to cause the selector to output the composite signal when the detector detects that the signal level becomes lower than the threshold value while the broadcast signal is received by, the tuner, wherein the threshold value is independent of whether or not the video encoder is able to convert the data into the Y/C signal.
