Abstract

A recording system includes an information receiver having a function of decoding a general-purpose data-description language, and a recorder having a data recording region for recording data from the information receiver and a document-type-definition recording region for recording at least document-type-definition information on the general-purpose data-description language. When being linked to the information receiver, the recorder transmits the recorded document-type-definition information to the information receiver, and the information receiver transmits, based on the received document-type-definition information, predetermined data to the recorder.

Claims

1. A recording system, comprising:

an information receiver having a function of decoding a general-purpose data-description language; and

a recorder having a data recording region for recording data from said information receiver and a document-type-definition recording region for recording at least document-type-definition information on said general-purpose data-description language;

wherein, when being linked to said information receiver, said recorder transmits the recorded document-type-definition information to said information receiver, and said information receiver transmits, based on the received document-type-definition information, predetermined data to said recorder.

2. A recording system according to

claim 1

, wherein, when said recorder is initially linked to said information receiver, said recorder transmits the document-type-definition information to said information receiver.

3. A recording system according to

claim 1

, wherein, when receiving the document-type-definition information, said information receiver extracts a predetermined command from among commands defined by the document type definition of the information, and accesses said recorder as instructed by the extracted command.

4. A recording system according to

claim 3

, wherein, after being extracted, said predetermined command is used as a transmission-request command to said recorder.

5. A recording system according to

claim 1

, wherein an information description stored in said recorder includes metadata.

6. A recording system according to

claim 1

, wherein the document-type-definition information in said recorder comprises a plurality of document type definitions.

7. A recording system according to

claim 1

, wherein said recorder includes a hard disk drive.

8. A recording system according to

claim 1

, wherein said information receiver is a set-top box or an information apparatus.

9. A recording system according to

claim 1

, wherein said general-purpose data-description language is the extensible markup language.

10. A recording system, comprising:

an information receiver having a function of decoding a general-purpose data-description language; and

a recorder having a data recording region for recording data from said information receiver and a document-type-definition recording region for recording at least a document type definition of said general-purpose data-description language, said recorder also having a function of decoding said general-purpose data-description language;

wherein said information receiver transmits document-type-definition information created in said general-purpose data-description language to said recorder, and based on the received document-type-definition information, said recorder performs recording to said data recording region and/or the setting of a display mode.

11. A recording system according to

claim 10

, wherein, when said information receiver is initially linked to said recorder, said information receiver transmits the document-type-definition information to said recorder.

12. A recording system according to

claim 10

, wherein the recording to said data recording region is based on a data format included in the received document-type-definition information.

13. A recording system according to

claim 10

, wherein, when transmitting the document-type-definition information, said information receiver extracts a predetermined command from among commands defined by the document type definition of the information, and accesses said recorder as instructed by the extracted command.

14. A recording system according to

claim 10

, wherein, after being extracted, said predetermined command is used as a transmission-request command to said recorder.

15. A recording system according to

claim 10

, wherein the document-type-definition information recorded in said recorder includes metadata.

16. A recording system according to

claim 10

, wherein the document-type-definition information in said information receiver which can be transmitted to said recorder comprises a plurality of document type definitions.

17. A recording system according to

claim 10

, wherein said recorder includes a hard disk drive.

18. A recording system according to

claim 10

, wherein said information receiver is a set-top box or an information apparatus.

19. A recording system according to

claim 10

, wherein said general-purpose data-description language is the extensible markup language.
