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.

Claims

1. A television circuit, comprising in combination:

a television receiver having at least two video signal sources for receiving first and second video signals;

a decoder for extracting and decoding coded data as character information multiplexed into said video signals;

a video processing circuit for receiving said video signals and processing said video signals for display on a video display; and

switching means for receiving said first and second video signals and supplying a first selected one of said first and second video signals to said decoder for decoding said coded data, and for supplying a second selected one of said first and second video signals to said video processing circuit,

wherein said first selected one of said video signals from said decoder, and said second selected one of said video signals from said video processing circuit, are combined so as to be displayed simultaneously on the video display.

2. The apparatus of claim 1, further comprising a first tuner and wherein said first video signal is produced by said first tuner.

3. The apparatus of claim 2, further comprising a second tuner and wherein said second video signal is produced by said second tuner.

4. The apparatus of claim 2, wherein said second video signal is received from an external video source.

5. The apparatus of claim 1, further comprising:

a multiple picture processor for producing a secondary picture, based on said first selected one of said first and second video signals, to be merged with a main picture, based on said second selected one of said first and second video signals, for display on said video display,

wherein said switching means further supplies said first selected one of said first and second video signals to said multiple picture processor, and

further wherein said multiple picture processor supplies the secondary picture to said video processing circuit.

6. The apparatus of claim 5, wherein said multiple picture processor includes a picture-in-picture processor.

7. The apparatus of claim 6, wherein said multiple picture processor includes a picture-outside-picture processor.

8. The apparatus of claim 1, wherein said decoder includes a closed caption decoder.

9. The apparatus of claim 1, wherein said decoder includes a closed caption/extended data services decoder.

10. A television circuit, comprising in combination:

a television receiver having at least three video signal sources for receiving first, second and third video signals;

a first tuner producing said first video signal;

a second tuner producing said second video signal;

means for receiving said third video signal from an external video source;

a closed caption/extended data services decoder for extracting and decoding coded data as closed caption data or extended data services data from said video signals,

a multiple picture processor for producing a secondary picture, based on a first selected one of said first, second and third video signals, to be merged with a main picture, based on a second selected one of said first, second and third video signals, for display on a video display;

a video processing circuit for receiving said video signals and processing said video signals for display on said video display; and

switching means for receiving said first, second and third video signals and supplying a third selected one of said first, second and third video signals to said decoder for extracting and decoding said coded data, for supplying said second selected one of said first, second and third video signals to said video processing circuit, and for supplying said first selected one of said first, second and third video signals to said multiple picture processing circuit,

wherein said main picture, said secondary picture and said coded data, extracted from said third selected one of said video signals, are combined so as to be displayed simultaneously on the video display.

11. The apparatus of claim 10, wherein said multiple picture processor includes a picture-in-picture processor.

12. The apparatus of claim 10, wherein said multiple picture processor includes a picture-outside-picture processor.

13. The apparatus of claim 10, further comprising a timing generator for extracting timing from a horizontal deflection signal and for generating timing signals for said decoder therefrom.

14. A television circuit, comprising in combination:

a television receiver having at least three video signal sources for receiving first, second and third video signals, wherein the third video signal is received from an external video source;

a first tuner wherein said first video signal is produced by said first tuner;

a second tuner wherein said first video signal is produced by said second tuner;

a decoder for extracting and decoding coded data as character information multiplexed into said video signals;

a video processing circuit for receiving said video signals and processing said video signals for display on a video display;

switching means for receiving said first, second and third video signals and supplying a first selected one of said first, second and third video signals to said decoder for decoding said coded data, and for supplying a second selected one of said first, second and third video signals to said video processing circuit,

wherein, said coded data from said first selected one of said video signals, and said second selected one of said video signals, are combined, so as be displayed simultaneously on the video display.

15. The apparatus of claim 14, further comprising:

a multiple picture processor for producing a secondary picture, based on said first selected one of said first, second and third video signals, to be merged with a main picture, based on said second selected one of said first, second and third video signals, for display on said video display,

wherein said switching means further supplies said first selected one of said first, second and third video signals to said multiple picture processor, and

further wherein said multiple picture processor supplies said secondary picture to said video processing circuit.

16. The apparatus of claim 15, wherein said multiple picture processor includes a picture-in-picture processor.

17. The apparatus of claim 15, wherein said multiple picture processor includes a picture-outside-picture processor.
