Abstract

A receiving apparatus includes a reception unit which receives moving image data transmitted from a source node, an acquisition unit which requests the source node to send information including a vendor name of the source node so as to acquire the vendor name of the source node from the source node, and a character generation unit which generates vendor name character data indicating the vendor name of the source node acquired by the acquisition unit. A synthesis unit superimposes the vendor name character data on the moving image data if the vendor name of the source node is acquired by the acquisition unit, and superimposes predetermined character data on the moving image data if the vendor name of the source node cannot be acquired by the acquisition unit.

Claims

1. A receiving apparatus comprising:

a reception unit which receives moving image data transmitted from a source node;

an acquisition unit which requests the source node to send information including a vendor name of the source node so as to acquire the vendor name of the source node from the source node;

a character generation unit which generates vendor name character data indicating the vendor name of the source node acquired by said acquisition unit; and

a synthesis unit which superimposes the vendor name character data on the moving image data if the vendor name of the source node is acquired by said acquisition unit, and superimposes predetermined character data on the moving image data if the vendor name of the source node cannot be acquired by said acquisition unit.

2. A receiving apparatus according to claim 1, further comprising:

an output unit which outputs the moving image data, on which the vendor name character data are superimposed, to an external apparatus if the vendor name of the source node is acquired by said acquisition unit, and outputs the moving image data, on which the predetermined character data are superimposed, to the external apparatus if the vendor name of the source node cannot be acquired by said acquisition unit.

3. A receiving apparatus according to claim 1, further comprising:

a display unit which displays the moving image data, on which the vendor name character data are superimposed if the vendor name of the source node is acquired by said acquisition unit, and displays the moving image data, on which the predetermined character data are superimposed if the vendor name of the source node cannot be acquired by said acquisition unit.

4. A receiving apparatus according to claim 1, wherein said acquisition unit acquires the vendor name of the source node from a configuration ROM of included in the source node.

5. A receiving apparatus according to claim 1, wherein said synthesis unit controls the process of superimposing the vendor name character data on the moving image data, according to the process of receiving the moving image data.

6. A receiving apparatus according to claim 1, wherein said synthesis unit stops superimposing the vendor name character data on the moving image data if said reception unit stops receiving the moving image data.

7. A receiving apparatus comprising:

a reception unit which receives moving image data transmitted from a source node;

an acquisition unit which requests the source node to send information including a model name of the source node so as to acquire the model name of the source node from the source node;

a character generation unit which generates model name character data indicating the model name of the source node acquired by said acquisition unit; and

a synthesis unit which superimposes the model name character data on the moving image data if the model name of the source node is acquired by said acquisition unit, and

superimposes predetermined character data on the moving image data if the model name of the source node cannot be acquired by said acquisition unit.

8. A receiving apparatus according to claim 7, further comprising:

an output unit which outputs the moving image data, on which the model name character data are superimposed, to an external apparatus if the model name of the source node is acquired by said acquisition unit, and outputs the moving image data, on which the predetermined character data are superimposed, to the external apparatus if the model name of the source node cannot be acquired by said acquisition unit.

9. A receiving apparatus according to claim 7, further comprising:

a display unit which displays the moving image data, on which the model name character data are superimposed if the model name of the source node is acquired by said acquisition unit, and displays the moving image data, on which the predetermined character data are superimposed if the model name of the source node cannot be acquired by said acquisition unit.

10. A receiving apparatus according to claim 7, wherein said acquisition unit acquires the model name of the source node from a configuration ROM included in the source node.

11. A receiving apparatus according to claim 7, wherein said synthesis unit controls the process of superimposing the model name character data on the moving image data, according to the process of receiving the moving image data.

12. A receiving apparatus according to claim 7,

wherein said synthesis unit stops superimposing the model name character data on the moving image data if said reception unit stops receiving the moving image data.
