Abstract

This information display system includes an input device, a computer, a receiving apparatus including a receiving portion and a control portion and a display portion, and a user can set whether to transmit operating information from the computer to the receiving apparatus in at least either the computer or the receiving apparatus in the information display system.

Claims

1. An information display system comprising:

an input device to which a user inputs operating information;

a computer connected with said input device, including a transmitting portion for transmitting said operating information input through said input device;

a receiving apparatus including a receiving portion for receiving said operating information transmitted by said computer and a control portion capable of performing display processing of a cursor on the basis of said operating information of said input device; and

a display portion provided on a side of said receiving apparatus, capable of displaying an image and displaying an image on which said display processing for composing said cursor with an image is performed by said control portion of said receiving apparatus on the basis of said operating information of said input device, wherein

the user can set whether to transmit said operating information from said computer to said receiving apparatus in at least either said computer or said receiving apparatus.

2. The information display system according to claim 1, wherein

said input device includes a pointing device,

said operating information includes information regarding a position of said pointing device, and

said control portion of said receiving apparatus is formed to compose said cursor with an image on the basis of the information regarding a position of said pointing device.

3. The information display system according to claim 2, further comprising a conversion portion for converting the information regarding a position of said pointing device so that said cursor can be composed with an image when a screen resolution set in said computer and a screen resolution set in said receiving apparatus are different from each other.

4. The information display system according to claim 3, wherein

said conversion portion converts the information regarding a position of said pointing device on the basis of a ratio of said screen resolution set in said receiving apparatus to said screen resolution set in said computer.

5. The information display system according to claim 1, wherein

said receiving apparatus further includes a first memory portion storing a program for transmitting said operating information input to said computer through said input device and a program transmitting portion transmitting said program to said computer,

said computer further includes a program receiving portion receiving said program from said receiving apparatus and a second memory portion storing received said program,

said receiving apparatus transmits said program to said computer when said receiving apparatus and said computer are connected to each other so that said program is stored in said second memory portion of said computer, and

said computer transmits said operating information input through said input device on the basis of said program stored in said second memory portion.

6. The information display system according to claim 5, wherein

the user sets whether to transmit said operating information from said computer to said receiving apparatus, and said computer further transmits said operating information to said receiving apparatus when the user sets said computer to transmit said operating information on the basis of said program.

7. The information display system according to claim 1, wherein

said computer transmits said operating information to said receiving apparatus without analyzing said operating information when the user sets said computer to transmit said operating information.

8. The information display system according to claim 1, wherein

said computer further includes an image transmitting portion for transmitting an image of said computer to said receiving apparatus independently of said transmitting portion, and

said receiving apparatus further includes an image receiving portion for receiving the image of said computer from said image transmitting portion independently of said receiving portion.

9. The information display system according to claim 8, wherein

said computer transmits said operating information to said receiving portion of said receiving apparatus through said transmitting portion when the user sets said computer to transmit said operating information, and said computer analyzes said operating information and prepares the image of said computer to transmit the image of said computer to said image receiving portion of said receiving apparatus through said image transmitting portion when the user sets said computer not to transmit said operating information.

10. The information display system according to claim 1, wherein

said computer transmits both the image of said computer and said operating information through said transmitting portion, and

said receiving portion of said receiving apparatus receives both the image of said computer and said operating information.

11. The information display system according to claim 1, further comprising display means for visually informing the user whether to transmit said operating information from said computer to said receiving apparatus.

12. The information display system according to claim 11, wherein

said display means displays a notice that said operating information has not been received on said display portion when the user sets said receiving apparatus to transmit said operating information and said operating information is not transmitted from said computer to said receiving apparatus.

13. The information display system according to claim 1, further comprising a remote controller for allowing the user to operate said receiving apparatus, wherein

said control portion of said receiving apparatus is formed to be capable of prioritizing processing based on an operation of said remote controller by the user over processing based on said operating information of said input device.

14. The information display system according to claim 1, wherein

said operating information includes information regarding a movement amount of said input device,

said display portion displays an image on which display processing is performed by said control portion of said receiving apparatus such that said cursor moves between a plurality of selection icons, and

said control portion of said receiving apparatus performs said display processing such that said cursor moves between the plurality of selection icons every prescribed said movement amount.

15. An information display apparatus, comprising:

a receiving apparatus including a receiving portion for receiving operating information of an input device transmitted by a computer connected with said input device to which a user inputs said operating information and a control portion capable of performing display processing of a cursor on the basis of said operating information of said input device; and

a display portion capable of displaying an image and displaying an image on which said display processing for composing said cursor with an image is performed by said control portion of said receiving apparatus on the basis of said operating information of said input device, wherein

the user can set whether to transmit said operating information from said computer to said receiving apparatus.

16. The information display apparatus according to claim 15, wherein

said receiving apparatus includes a television apparatus or a set top box.

17. The information display apparatus according to claim 15, wherein

said input device includes a pointing device, and said operating information includes information regarding a position of said pointing device, and

said control portion of said receiving apparatus is formed to compose said cursor with an image on the basis of the information regarding a position of said pointing device.

18. The information display apparatus according to claim 17, further comprising a conversion portion for converting the information regarding a position of said pointing device so that said cursor can be composed with an image when a screen resolution set in said computer and a screen resolution set in said receiving apparatus are different from each other.

19. The information display apparatus according to claim 15, further comprising display means for visually informing the user whether to transmit said operating information from said computer to said receiving apparatus.

20. The information display apparatus according to claim 15, further comprising a remote controller for allowing the user to operate said receiving apparatus, wherein
