Abstract

A multimedia communication apparatus enabling remote control, by generating operation guidance information for operating this apparatus, transmitting thus generated operation guidance information to a partner apparatus, then receiving and recognizing information on operation from the partner apparatus in response to the operation guidance information, and effecting an operation according to thus recognized information on operation.

Claims

1. A multimedia communication system for communication between a first communication apparatus and a second communication apparatus, wherein:

said first communication apparatus includes;

generation means for generating operation guidance information for operating said first communication apparatus from said second communication apparatus;

encoding means for encoding the operation guidance information generated by said generation means; and

transmission means for transmitting said encoded operation guidance information to said second communication apparatus; and

said second communication apparatus includes;

reception means for receiving said operation guidance information;

decoding means for decoding said received operation guidance information; and

display means for displaying said received operation guidance information on a monitor,

wherein said generation means has a function to synthesize an image and a guidance character with each other, and generates the operation guidance information obtained by synthesizing the image and the guidance character with each other.

2. A multimedia communication system according to claim 1, wherein said first communication apparatus further includes recognition means for recognizing a data format receivable by said second communication apparatus, and said encoding means is adapted to encode said operation guidance information according to the result of recognition by said recognition means.

3. A multimedia communication system according to claim 1, wherein said second communication apparatus further includes input means for effecting a process according to said operation guidance information, and said generation means is adapted to generate operation guidance information according to the kind of said input means.

4. A multimedia communication system according to claim 1, wherein said operation guidance information is provided in plural kinds according to the function of said first communication apparatus.

5. A multimedia communication system according to claim 4, wherein said second communication apparatus is adapted to transmit control information to said first communication apparatus, according to an input from the input means in response to the operation guidance information displayed on the display means.

6. A multimedia communication system according to claim 3 or 5, wherein said input means is composed of push buttons capable of generating DTMF tones.

7. A multimedia communication system according to claim 3 or 5, wherein said input means is composed of a keyboard, a pen input unit or a mouse.

8. A multimedia communication system according to claim 1, wherein said first communication apparatus further includes identification means for confirming an identification number, and is adapted to transmit specified operation guidance information to said second communication apparatus, according to the confirmation by said identification means of an identification number transmitted from said second communication apparatus.

9. A multimedia information transmitting apparatus comprising:

generation means for generating operation guidance information for enabling an external apparatus to operate said multimedia information transmitting apparatus;

encoding means for encoding the operation guidance information generated by said generation means; and

transmission means for transmitting said encoded operation guidance information to said external apparatus,

wherein said generation means has a function to synthesize an image and a guidance character with each other, and generates the operation guidance information obtained by synthesizing the image and the guidance character with each other.

10. A multimedia information transmitting apparatus according to claim 9, further comprising recognition means for recognizing a data format receivable by said external apparatus, wherein said encoding means is adapted to encode said operation guidance information according to the result of recognition by said recognition means.

11. A multimedia transmitting apparatus according to claim 9, wherein said operation guidance information includes plural kinds of operation guidance information and the kind of operation guidance information is provided according to the function of the multimedia transmitting apparatus.

12. A multimedia information transmitting apparatus according to claim 9, further comprising identification means for confirming an identification number, wherein said multimedia information transmitting apparatus is adapted to transmit specified operation guidance information to said external apparatus according to the confirmation by said identification means of an identification number transmitted from said external apparatus.

13. A television telephone apparatus which has an image transmission/reception function with a plurality of communication partner terminals, comprising:

transmission means for transmitting an identification signal to a communication partner'"'"'s television telephone apparatus; and

reception means for receiving a remote control menu image of the communication partner'"'"'s television telephone apparatus which remote control menu image is generated by the communication partner'"'"'s television telephone apparatus, and an image by which the communication partner'"'"'s terminal can be discriminated, in response to a confirmation of the identification signal by the communication partner'"'"'s television telephone apparatus.

14. An apparatus according to claim 13, further comprising output means for outputting a remote control indication on the basis of the remote control menu image.

15. An apparatus according to claim 13, wherein the communication partner'"'"'s television telephone apparatus has a camera, and a remote control is a camera control.

16. An apparatus according to claim 13, wherein the communication partner'"'"'s television telephone apparatus has an automatic recording function, and a remote control is an automatic recording and reproducing control.

17. An apparatus according to claim 13, wherein the communication partner'"'"'s television telephone apparatus has an automatic recording message transmission function, and a remote control is a registration control of an automatic recording message.

18. An apparatus according to claim 13, wherein the communication partner'"'"'s television telephone apparatus has an automatic recording function, and the remote control menu image is an automatic recording list image of the communication partner'"'"'s television telephone apparatus.

19. An apparatus according to claim 13, wherein the communication partner'"'"'s television telephone apparatus has an automatic recording function, and automatic recording and automatic reproducing are performed according to a remote control menu in an interactive manner.
