    摘要: A color television receiver receiving two television signals of different channels, compressing the time axis of one of the television signals, and inserting this compressed television signal in a portion of the other television signal for displaying the pictures of the two channels on the same screen. In the receiver, the luminance signal, chrominance signal and synchronizing signal are derived from each of the received two television signals. A writing clock pulse signal is produced on the basis of one of the synchronizing signals for writing the luminance signal and chrominance signal in the corresponding television signal in a memory circuit, while a reading clock pulse signal is produced on the basis of the other synchronizing signal to read out the luminance signal and chrominance signal from the memory circuit in a relation in which these signals are compressed in the time axis. After the luminance signal and chrominance signal read out from the memory circuit are adjusted in their signal levels relative to the luminance signal and chrominance signal in the other television signal, a portion of the luminance signal and chrominance signal in the other television signal is replaced by the luminance signal and chrominance signal read out from the memory circuit so that the pictures of the two channels can be displayed on the same screen.
