Disclosed is an apparatus and method for expressing a query for searching multimedia data. The apparatus and method of the present invention expresses diverse query types in MPEG-7 query formats and uses field types to re use a designated region. The apparatus for expressing a query inputted from a user for multimedia data search includes: an input means for receiving a query for multimedia data search from a user; and a query expression means for expressing the input query in a field type, wherein the field type includes at least one among identifier information indicating identification (ID) information of a field presenting a search condition included in the input query; type information indicating data type information of the field; and reference information indicating identifier information of another field for reference. The present invention is applied to MPEG-7 query formats.

In a method for providing multimedia services in a communication system, a request message for requesting contract information on users' multimedia services are received from a terminal according to service requests of the multimedia services to be received by the users. A query message for searching for the contract information in a database is generated corresponding to the request message, and the query message is transmitted to the database. The contract information is searched in the database through a Moving Picture Experts Group (MPEG) query format protocol based on the query message, and a query result message containing the contract information is received from the database in response to the query message. The contract information is acknowledged in the query result message, and a response message containing the contract information is generated. Then, the response message is transmitted to the terminal.

摘要:
Disclosed is an apparatus and method for retrieving multimedia contents represented in a Moving Picture Experts Group (MPEG) 7 by transforming a user query into an MPEG-7 query format. The method for retrieving multimedia contents includes: representing a user query by using an indicator indicating a specific region of a Moving Picture Experts Group 7 (MPEG-7) document and a reference for referring to the indicator; analyzing a meaning of the user query represented by using the indicator and the reference to thereby produce an analysis result; and retrieving multimedia contents according to the analysis result. The present research can satisfy more than two retrieval conditions within the same structure in an MPEG-7 query format and it can also clearly represent that two different MPEG-7 documents are referred to. Since the meaning of a user query is analyzed accurately during retrieval process, it is possible to precisely retrieve multimedia contents.
