Abstract

An information management system has an information management apparatus that receives a data stream with a general-purpose format, which is constituted of data and additional information, from a data-supplying system and separates the additional information from the data stream to hold and manage the data obtained by separating the additional information from the data stream. The information management system has a data storage device that stores the data obtained by separating the additional information from the data stream with the information management apparatus. The data is stored in the data storage device as it is with the data having the general-purpose format.

Claims

1. An information management system comprising:

an information management apparatus that receives a data stream constituted of data and additional information from a data-supplying system, said data stream having a general-purpose format, and separates the additional information from the data stream to hold and manage the data obtained by separating the additional information from the data stream; and

a data storage device that stores the data obtained by separating the additional information from the data stream with the information management apparatus.

2. The information management system of claim 1, wherein, when reproducing the data, the information management apparatus:

receives the additional information;

reads data corresponding to the received additional information out of the data storage device;

combines the additional information and the data to produce the data stream with the general-purpose format; and

transmits the data stream to a data demand system.

3. The information management system of claim 1, further comprising an information recording/reproducing apparatus that decodes the data read out of the data storage device,

wherein, when reproducing the data, the information management apparatus controls the information recording/reproducing apparatus to:

receive the additional information;

read data corresponding to the received additional information out of the data storage device; and

decode the data read out of the data storage device to transmit the decoded data to a data demand system.

4. An information management system comprising:

information management means for receiving a data stream constituted of data and additional information from a data-supplying system, said data stream having a general-purpose format, and separating the additional information from the data stream to hold and manage the data obtained by separating the additional information from the data stream; and

data storage means for storing the data obtained by separating the additional information from the data stream with the information management means.

5. An information management system comprising:

an information recording/reproducing apparatus that receives data with a non-general purpose format from a data-supplying system and encodes the data;

an information management apparatus that holds and manages additional information which is added to the data encoded by the information recording/reproducing apparatus; and

a data storage device that stores the data encoded by the information recording/reproducing apparatus.

6. The information management system of claim 5, wherein, when reproducing the data, the information management apparatus controls the information recording/reproducing apparatus to:

receive the additional information;

read data corresponding to the received additional information out of the data storage device; and

decode the data read out of the data storage device to transmit the decoded data to a data demand system.

7. The information management system of claim 5, wherein, when reproducing the data, the information management apparatus:

receives the additional information;

reads data corresponding to the received additional information out of the data storage device;

combines the data read out of the data storage device and the additional information to produce a data stream with a general-purpose format; and

transmits the data stream to a data demand system.

8. An information management apparatus that manages a data stream with a general-purpose format, said data stream being constituted of data and additional information,

Wherein, when recording the data, the information management apparatus receives the data stream from a data-supplying system, separates the additional information from the data stream, and stores the data obtained by separating the additional information from the data stream on data storage device.

9. The information management apparatus of claim 8, wherein, when reproducing the data, the information management apparatus:

receives the additional information;

reads data corresponding to the received additional information out of the data storage device;

combines the additional information and the data to produce a data stream with a general-purpose format; and

transmits the data stream to a data demand system.

10. The information management apparatus of claim 8, wherein, when reproducing the data, the information management apparatus manages an information management system to:

receive the additional information;

read the data corresponding to the received additional information out of the data storage device;

decode the data read out of the data storage device; and

transmit the decoded data to a data demand system.

11. An information management apparatus that manages a data stream with a general-purpose format, said data stream being constituted of data and additional information,

Wherein, when recording the data, the information management apparatus receives the data stream from a data-supplying system, separates the additional information from the data stream, and stores the data obtained by separating the additional information from the data stream on data storage means.

12. An information management apparatus that is connected with an information recording/reproducing system, which receives data with a non-general purpose format from a data-supplying system and encodes the data,

Wherein, when recording the data, the information management apparatus holds and manages additional information that is added to the data encoded by the information recording/reproducing system, and stores the encoded data on data storage device.

13. The information management apparatus of claim 12, wherein, when reproducing the data, the information management apparatus controls the information recording/reproducing system to:

receive the additional information;

read data corresponding to the received additional information out of the data storage device; and

decode the data read out of the data storage device to transmit the decoded data to a data demand system.

14. The information management apparatus of claim 12, wherein, when reproducing the data, the information management apparatus:

receives the additional information;

reads data corresponding to the received additional information out of the data storage device;

combines the data read out of the data storage device and the additional information to produce a data stream with a general-purpose format; and

transmits the data stream to a data demand system.

15. An information management method comprising, when recording data, the steps of:

receiving the data stream with a general-purpose format from a data-supplying system, said data stream being constituted of the data and additional information;

separating the additional information from the data stream received from the data-supplying system;

storing the data obtained by separating the additional information from the data stream on a first memory area, and

storing the additional information that is separated from the data stream on a second memory area.

16. The information management method of claim 15, further comprising, when reproducing the data, the steps of:

receiving the additional information;

reading the received additional information out of the second memory area;

reading the data corresponding to the received additional information out of the first memory area;

combining the additional information and the data to produce the data stream with the general-purpose format; and
