Abstract
A television system which selectively receives additional information multiplexed in a video-signal source different from and other than a video-signal source currently being watched. A video signal V7 supplied to a CCD/EDS data extractor 7 is selected independently of a video signal V5 for a main screen of a CRT 10 or a video signal V6 for an auxiliary screen of the CRT 10 displayed by a PinP (PoutP) function. Accordingly, captions to be displayed are not limited to additional information multiplexed in the video signal V5 for the main screen displayed on the CRT 10. As a result, additional information multiplexed in a video signal for the auxiliary screen other than that for the main screen or multiplexed in an external video signal V2 can also be displayed as well.
