A TV receiver with built-in multiple functions such as TV, PIP, and VCR functions, is disclosed. The TV receiver processes a PIP signal in response to switching control by a microcomputer without using a separate tuner for PIP processing, and causes picture and audio signals to be selected for main and subscreen displays by controlling switches using a single microcomputer.
