Abstract

A communication relay device adds information to communication data without depending on a communication application of a communication terminal. The relay device (1) includes a relay control portion (13), a control information database (14), an adder portion (15) and a database for addition (16). The relay control portion (13) controls the adder portion (15) in accordance with information accumulated in the control information DB 14. The adder portion (15) adds the additional data accumulated in the database for addition (16) to decoded first contents in accordance with a control instruction by the relay control portion (13).

Claims

1. A communication relay method performed by a relay device that relays communication between two computers, the method comprising the steps of:

establishing connection with the two computers;

receiving first contents transmitted from one of the two computers to the other as a payload;

accumulating first additional data to be added to the first contents; and

transmitting second contents containing the first contents and the first additional data as a payload to the computer that is a destination of the first contents;

wherein the first contents to be received in the receiving step contain image data and/or audio data.

2. A communication relay method according to claim 1, further comprising the step of combining the first contents with the first additional data so as to generate the second contents if each of the first contents and the first additional data contain image data and/or text data.

3. A communication relay method according to claim 2, wherein the accumulating step includes further accumulation of output control data for designating a display area of the first additional data, and the combining step includes combining the first contents with the first additional data in accordance with the output control data.

4. A communication relay method according to claim 2, wherein the accumulating step includes further accumulation of output control data for designating a speed of scrolling the first additional data if the first additional data contain text data, and the combining step includes combining the first contents with the first additional data in accordance with the output control data.

5. A communication relay method according to claim 2, wherein the accumulating step includes further accumulation of output control data for designating an output frequency of the first additional data if the first additional data contain moving image data, and the combining step includes combining the first contents with the first additional data in accordance with the output control data.

6. A communication relay method according to claim 1, further comprising the step of mixing the first contents with the first additional data so as to generate mixing data if each of the first contents and the first additional data contain audio data, wherein the transmitting step includes transmitting the mixing data.

7. A communication relay method according to claim 6, wherein the accumulating step includes further accumulation of output control data for designating an output sound level of the first additional data, and the mixing step includes mixing the first contents with the first additional data in accordance with the output control data.

8. A communication relay method according to claim 1, further comprising the step of adjusting quality of image data and/or audio data contained in the first contents, wherein the transmitting step includes transmitting the first additional data and first contents after adjusted in the quality adjusting step.

9. A communication relay device for relaying communication between two computers, comprising:

unit for establishing connection with the two computers;

unit for receiving first contents transmitted from one of the two computers to the other as a payload;

unit for accumulating first additional data to be added to the first contents; and

unit for transmitting second contents containing the first contents and the first additional data as a payload to the computer that is a destination of the first contents, wherein

the first contents to be received by the receiving unit contain image data and/or audio data.

10. A communication relay program that is executed by a relay device for relaying communication between two computers, the program functionalizing the relay device as unit for establishing connection with the two computers;

unit for receiving first contents transmitted from one of the two computers to the other as a payload;

unit for accumulating first additional data to be added to the first contents; and

unit for transmitting second contents containing the first contents and the first additional data as a payload to the computer that is a destination of the first contents, wherein

the first contents to be received by the receiving unit contain image data and/or audio data.

11. A computer-readable recording medium storing a communication relay program that is executed by a relay device for relaying communication between two computers, the program functionalizing the relay device as unit for establishing connection with the two computers;

unit for receiving first contents transmitted from one of the two computers to the other as a payload;

unit for accumulating first additional data to be added to the first contents; and

unit for transmitting second contents containing the first contents and the first additional data as a payload to the computer that is a destination of the first contents, wherein

the first contents to be received by the receiving unit contain image data and/or audio data.

12. A communication relay method performed by a relay device that relays communication between two computers, the method comprising the steps of:

establishing connection with the two computers;

receiving second contents containing first contents transmitted from one of the two computers to the other and first additional data added to the first contents by the other relay device as a payload;

accumulating second additional data to be added to the first contents;

reconstructing the first contents by removing the first additional data from the second contents; and

transmitting third contents containing the first contents obtained in the reconstructing step and the second additional data as a payload to the computer that is a destination of the first contents.

13. A communication relay method performed by a relay device that relays communication between two computers, the method comprising the steps of:

establishing connection with the two computers;

receiving first contents transmitted from one of the two computers to the other as a payload;

accumulating first additional data to be added to the first contents;

deciding whether or not second additional data that was added to the first contents by a relay device except the relay device are contained in the reception data; and

transmitting third contents containing the first contents and the second additional data as a payload to the computer that is a destination of the first contents if the reception data contain the second additional data, while transmitting second contents containing the first contents and the first additional data as a payload to the computer that is a destination of the first contents if the reception data does not contain the second additional data, wherein

the first contents to be received in the receiving step contain image data and/or audio data.
