Abstract

This invention relates to an information-processing apparatus for transmitting streaming data through a network, including: an addition element for adding information used for carrying out processing on streaming data to the streaming data; a storage element for storing the streaming data and the information added to the streaming data by the addition element; and a transmission element for transmitting the streaming data which is stored by the storage element and which includes the information.

Claims

1. An information-processing apparatus for transmitting streaming data through a network, comprising:

addition means for adding information used for carrying out processing on streaming data to said streaming data;

storage means for storing said streaming data and said information added to said streaming data by said addition means; and

transmission means for transmitting said streaming data which is stored by said storage means and which includes said information.

2. An information-processing apparatus according to claim 1, wherein said information includes a decoder for decoding said streaming data.

3. An information-processing apparatus according to claim 1, wherein said information includes an encoder for encoding said streaming data.

4. An information-processing apparatus according to claim 1, wherein said information includes a transcoder for transcoding said streaming data.

5. An information-processing apparatus according to claim 1, wherein said information includes a scrambler for scrambling said streaming data.

6. An information-processing apparatus according to claim 1, wherein said information includes a descrambler for descrambling said streaming data.

7. An information-processing method adopted by an information-processing apparatus for transmitting streaming data through a network, comprising:

an addition step of adding information used for carrying out processing on streaming data to said streaming data;

a storage step of storing said streaming data and said information added to said streaming data in said addition step; and

a transmission step of transmitting said streaming data which is stored in said storage step and which includes said information.

8. A program to be executed by a computer for controlling an information-processing apparatus for transmitting streaming data through a network, said program comprising:

an addition step of adding information used for carrying out processing on streaming data to said streaming data;

a storage step of storing said streaming data and said information added to said streaming data in said addition step; and

a transmission step of transmitting said streaming data which is stored in said storage step and which includes said information.

9. An information-processing apparatus for receiving streaming data through a network, comprising:

reception means for receiving streaming data to which information used in carrying out processing on said streaming data is added;

processing means for carrying out processing on said streaming data received by said reception means in accordance with said information added to said streaming data; and

output means for outputting a result of said processing carried out on said streaming data by said processing means.

10. An information-processing method adopted by an information-processing apparatus for receiving streaming data through a network, comprising:

a reception step of receiving streaming data to which information used in carrying out processing on said streaming data is added;

a processing step of carrying out processing on said streaming data received in said reception step in accordance with said information added to said streaming data; and

an output step of outputting a result of said processing carried out on said streaming data in said processing step.

11. A program to be executed by a computer for controlling an information-processing apparatus for receiving streaming data through a network, said program comprising:

a reception step of receiving streaming data to which information used in carrying out processing on said streaming data is added;
