Claims7
A switching apparatus for PCM or video signals, comprising:
- (a) an input terminal supplied with a PCM signal or a video signal;
- (b) an output terminal;
- (c) a first means coupled to said input terminal for compensating a drop-out contained in said video signal when said video signal is supplied to said input terminal;
- (d) a second means coupled to said input terminal for detecting a specific information signal contained in said PCM signal when said PCM signal is supplied to said input terminal;
- and
- (e) a third means coupled to said second means for switching so as to derive said PCM signal from said input terminal to said output terminal without through said first means in response to an output of said second means.
