ABSTRACT:
A television receiver is disclosed, which receives two television signals and compresses a time axis of one of the television signals and inserts the compressed signal to a portion of the other television signal to display both signals on the same screen. A signal indicating a boundary of the two images is produced from a synchronizing signal derived from one of the two received television signals and the boundary indicating signal is superimposed on one or both of a brightness signal and a chrominance signal to display the boundary.
