Abstract
A 'channel guide' system, including a picture-in-picture processing unit for displaying an array of images corresponding to respective channels or auxiliary televisions signals on a display screen is automatically activated when the video signal currently being processed by the receiver no longer contains program information (e.g., either does not contain valid video information, or represents a uniform screen). In a VCR, the 'channel guide' system is automatically initiated in response to the detection of the end of tape.
