ABSTRACT:
A signal selection circuit is disclosed for use in an intelligence TV. The intelligence TV can display a signal prioritized in the order of a TV OSD signal, a PIP signal, an information signal, and a TV signal. The structure for carrying out this prioritization includes a TV signal processor for processing a TV signal and outputting a TV signal, an information signal processor for outputting an information signal by decoding the received information data from value added networks and for outputting a first switching control signal by recognizing a selection mode, and a PIP signal processor for processing the TV signals as a main picture signal and a sub picture signal and for outputting a PIP signal and a second switching control signal. A TV microcomputer generates an OSD for the operation of the TV. Plural switching devices operate responsively to switching control signals from the TV microcomputer, the information signal processing unit and the PIP signal processor. A driver supplies the cathode ray tube with the signal selected by the switching devices.
