Abstract

Provided are a method and apparatus for generating separate rule data using a database management system (DBMS) based language in order to efficiently manage usage rules of content. The method of providing usage rule data of content included in a mobile storage medium connected to a content reproduction device, the method includes: generating first rule data that is a set of rules used to manage the usage rule data based on a data structure of a database management system (DBMS); and generating second rule data that is a set of rules used to access the usage rule data using the first rule data.

Claims

1. A method of providing usage rule data of content included in a mobile storage medium connected to a content reproduction device, the method comprising:

generating first rule data that is a set of rules used to manage the usage rule data based on a data structure of a database management system (DBMS); and

generating second rule data that is a set of rules used to access the usage rule data using the first rule data.

2. The method of claim 1, wherein the first rule data presents a data record of the usage rule data in a table format defined by the data structure of the DBMS, and includes commands used to carry out at least one of actions of creating, selecting, and updating the data record.

3. The method of claim 2, wherein the first rule data is expressed using a structured query language (SQL).

4. The method of claim 3, wherein the command used to carry out the action of creating the data record generates a table including a data body comprising at least one of data items of the usage rule data.

5. The method of claim 4, wherein the command used to carry out the action of selecting the data record selects the data item from the table and stores the data item in a predetermined variable in a memory.

6. The method of claim 5, wherein the command used to carry out the action of updating the data record assigns a value stored in the predetermined variable to a predetermined data item of the table.

7. The method of claim 4, wherein the data item includes at least one of an ID, a first date, an end date, a usage duration, a copy permission number, and extra information of the usage rule data.

8. The method of claim 5, wherein the data item includes at least one of an ID, a first date, an end date, a usage duration, a copy permission number, and extra information of the usage rule data.

9. The method of claim 6, wherein the data item includes at least one of an ID, a first date, an end date, a usage duration, a copy permission number, and extra information of the usage rule data.

10. The method of claim 7, wherein the second rule data includes a constant data block used to determine a constant value for accessing the usage rule data and an execution data block used to establish an execution action for accessing the usage rule data.

11. The method of claim 8, wherein the second rule data includes a constant data block used to determine a constant value for accessing the usage rule data and an execution data block used to establish an execution action for accessing the usage rule data.

12. The method of claim 9, wherein the second rule data includes a constant data block used to determine a constant value for accessing the usage rule data and an execution data block used to establish an execution action for accessing the usage rule data.

13. The method of claim 8, wherein the execution data block includes at least one of a name of the execution action, an argument, a constant, and an execution code.

14. The method of claim 11, wherein the execution data block includes at least one of a name of the execution action, an argument, a constant, and an execution code.

15. The method of claim 12, wherein the execution data block includes at least one of a name of the execution action, an argument, a constant, and an execution code.

16. A computer readable medium having recorded thereon first rule data that is a set of rules used to manage usage rule data of content included in a mobile storage medium, based on a data structure of a DBMS, and second rule data that is a set of rules used to access the usage rule data using the first rule data.

17. The medium of claim 16, wherein the first rule data presents a data record of the usage rule data in a table format defined by the data structure of the DBMS, and includes commands used to carry out at least one of actions of creating, selecting, and updating the data record.

18. The medium of claim 17, wherein the first rule data is expressed using an SQL.

19. The medium of claim 18, wherein the command used to carry out the action of creating the data record generates a table including a data body comprising at least one of data items of the usage rule data.

20. The medium of claim 19, wherein the command used to carry out the action of selecting the data record selects the data item from the table and stores the data item in a predetermined variable in a memory.

21. The medium of claim 20, wherein the command used to carry out the action of updating the data record assigns a value stored in the predetermined variable to a predetermined data item of the table.

22. The medium of claim 19, wherein the data item includes at least one of an ID, a first date, an end date, a usage duration, copy permission number, and extra information of the usage rule data.

23. The medium of claim 20, wherein the data item includes at least one of an ID, a first date, an end date, a usage duration, copy permission number, and extra information of the usage rule data.

24. The medium of claim 21, wherein the data item includes at least one of an ID, a first date, an end date, a usage duration, copy permission number, and extra information of the usage rule data.

25. The medium of claim 22, wherein the second rule data includes a constant data block used to determine a constant value for accessing the usage rule data and an execution data block used to establish an execution action for accessing the usage rule data.

26. The medium of claim 23, wherein the second rule data includes a constant data block used to determine a constant value for accessing the usage rule data and an execution data block used to establish an execution action for accessing the usage rule data.

27. The medium of claim 24, wherein the second rule data includes a constant data block used to determine a constant value for accessing the usage rule data and an execution data block used to establish an execution action for accessing the usage rule data.

28. The medium of claim 25, wherein the execution data block includes at least one of a name of the execution action, an argument, a constant, and an execution code.

29. The medium of claim 26, wherein the execution data block includes at least one of a name of the execution action, an argument, a constant, and an execution code.

30. The medium of claim 27, wherein the execution data block includes at least one of a name of the execution action, an argument, a constant, and an execution code.

31. An apparatus for providing usage rule data of content included in a mobile storage medium connected to a content reproduction device, the apparatus comprising:

a first generation unit which generates first rule data that is a set of rules used to present data record of the usage rule data in a table format defined by a data structure of a DBMS, and carries out at least one of actions of creating, selecting, and updating the data record; and

a second generation unit which generates second rule data that is a set of rules used to determine a constant value for accessing the usage rule data and establish an execution action for accessing the usage rule data.

32. A computer readable medium having recorded thereon a computer program for executing a method of generating first rule data that is a set of rules used to manage usage rule data based on a data structure of a DBMS;

and generating second rule data that is a set of rules used to access the usage rule data using the first rule data.
