Abstract

The present invention relates to a method or an operation for providing a personalized TV-Anytime metadata service. According to an embodiment of the present invention, there is provided a method of providing a table field element using a get_Data operation in the TV-Anytime metadata service. In the table field element provision method, a requested fields type element (RequestedFieldsType) required to designate a field of a metadata table is included in a query result value type in the SOAP query operation. A request message of the SOAP query operation is received. When the request message includes the requested fields type element for designating the query result value, a query result value corresponding to a designated table field is extracted from the requested fields type element included in the request message, and the query result value is transmitted using a response message of the SOAP operation.

Claims

1. A method of providing a TV-Anytime metadata service using a Simple Object Access Protocol (SOAP) query operation, comprising the steps of:

a) including a requested fields type element (RequestedFieldsType), required to designate a field of a metadata table, in a query result value type in the SOAP query operation;

b) receiving a request message of the SOAP query operation; and

c) when the request message includes the requested fields type element designated as the query result value, extracting a query result value corresponding to the designated table field from the requested fields type element included in the request message, and transmitting the query result value using a response message of the SOAP operation.

2. The TV-Anytime metadata service provision method according to claim 1, wherein the SOAP query operation is a get_Data operation.

3. The TV-Anytime metadata service provision method according to claim 1, wherein the requested fields type element included at step a) comprises:

a requested field sub-element for designating a field ID (fieldID) of the metadata table; and

a requested path sub-element for designating a path (Xpath) of the field ID (fieldID).

4. The TV-Anytime metadata service provision method according to claim 1, wherein the step c) is performed so that, if duplicated data having the same field ID (fieldID) exist in the query result value, the duplicated data are removed from the query result value.

5. The TV-Anytime metadata service provision method according to claim 1, wherein the metadata is program description metadata.

6. The TV-Anytime metadata service provision method according to claim 5, wherein the step c) is performed so that, if duplicated data having the same field ID (fieldID) exist in the query result value, the duplicated data are removed from the query result value.

7. The TV-Anytime metadata service provision method according to claim 5, wherein the requested fields type element included at step a) comprises:

a requested field sub-element for designating a field ID (fieldID) of the metadata table; and

a requested path sub-element for designating a path (Xpath) of the field ID (fieldID).

8. The TV-Anytime metadata service provision method according to claim 7, wherein the step c) is performed so that, if duplicated data having the same field ID (fieldID) exist in the query result value, the duplicated data are removed from the query result value.

9. The TV-Anytime metadata service provision method according to claim 5, wherein the requested fields type element (RequestedFieldsType) included at step a) is defined as follows;

10. A method of providing a TV-Anytime metadata service, the method providing a search on a field basis of a table using a get_Data operation in the TV-Anytime metadata service, comprising the steps of:

d) including, as a sub-element, a requested field element (RequestedFields) for designating a field of a table, in a requested table element (RequestedTables) as a query result value of the get_Data operation;

e) receiving a request message of the get_Data operation;

f) extracting a field designated in the requested field element from the table designated in the requested table element as a query result value in response to reception of the request message; and

g) transmitting the extracted query result value using a response message of the get_Data operation.

11. The TV-Anytime metadata service provision method according to claim 10, wherein the requested field element (RequestedFields) included at step d) includes a unit requested field element (RequestedField), which designates an ID of a field (fieldID) to be searched for, as a sub-element.

12. The TV-Anytime metadata service provision method according to claim 11, wherein the step d) is performed to assign an ID of a field (fieldID) to be searched for to an attribute of the unit requested field element.

13. The TV-Anytime metadata service provision method according to claim 12, wherein the requested field element included at step d) includes a requested path element (RequestedXPath) for designating a path of a field to be searched for, as a sub-element.

14. The TV-Anytime metadata service provision method according to claim 13, wherein the requested table element (RequestedTables) is defined as follows;
