There is provided a method for requesting an electronic document based on XML in which the electronic document is created using a syntax defining a structure of a constructed electronic document. The electronic document request method can include creating a request document including an element name/attribute name based on a previously prescribed syntax without defining an additional syntax for requesting the electronic document, requesting a supply of the electronic document having an information on the element name/attribute name recorded in the request document, and receiving the electronic document including the information on the requested element name/attribute name.

Electronic document request/supply method based on XML

Methods and apparatus for versioning an electronic document based on XML and methods and apparatus for providing an updated electronic document based on XML can use a version value. The electronic document being managed can use a syntax defining a structure of the structured electronic document. One method is characterized in that date information of when a content of the electronic document is changed is used as a version value.

Disclosed is a user history based multimedia service system, wherein user history data include a multimedia consumption type and/or consumption behavior of the user. The consumption type data includes a start time or end time of the multimedia content consumption (i.e., simple view data), content recording time and format, content backup time and format, and content transfer time and format. The consumption behavior data includes a content access/play data such as a normal finish, skimmed, skipped, slowed, or replay, and a stopped data of the content access/play. The consumption type or consumption behavior data include information on program identification and information on access to the consumption type/consumption behavior data. The respective data is provided for each user and program.

Multimedia service system based on user history

A user preference information structure having a multiple hierarchical structure in which an information is provided to a user according to a user preference in a multi-media environment consisting of an information provider and an information user, comprising user use information by using information desired by the user; user preference information of information desired by the user; and individual user preference information that is differently set depending on situations in which the user is put and positioned in a sub-tree of the user preference information. The hierarchical data structure is able to provide the user preference for providing information desired by the user is provided depending on the environment, based on which various information can be provided. The hierarchical data structure constructing the user preference makes it possible for the user to receive information fitting the situation in which he or she is put by using a proper individual user preference information, automatically or according to user's selection.

The present invention relates to a method for asynchronous multimedia content retrieval, which can be applied to TV-Anytime standard or MPEG standard. In summary, an asynchronous multimedia retrieval method is provided as including: a client establishing the first session as requesting to the server; transmitting to the server the retrieval inquiry message for contents that the server needs; terminating the first session after the retrieval inquiry; establishing the second session and requesting to the server the result for the retrieval inquiry at a certain point in time that the previously set time has passed; and receiving the retrieval result from the server and terminating the second session.

Disclosed are a method of constructing information on associate meanings between segments of a multimedia stream, which can describe the cause/effect or abstract/detail relationship between segments of the video streams to efficiently browse the video stream and a method of browsing a video using the same. The present invention defines the cause/effect or abstract/detail relationship between the segments, event intervals, scenes, shots, etc. existing within one video stream or between the video streams, and provides a method of describing the relationship in a data region based on the content of a video stream as well as a method of browsing a video by using the information on the cause/effect or abstract/detail relationship obtained by the aforementioned method. Accordingly, a video browsing on associate meanings is available with easy manipulation and easy access to a desired part, thereby providing an effective video browsing interface for easy browsing of desired segments in a short period of time.

Disclosed is 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 the table field designated from the requested fields type element included in the request message is extracted, and the query result value is transmitted using a response message of the SOAP operation.

A method for reproducing video contents includes the steps of: selecting a reproduction shot from video contents, based on a current location information and a shot index information; determining a reproduction section from the selected reproduction shot; and reproducing the determined reproduction section. After the determined reproduction section is reproduced, the above processes are repeated to next reproduction shots. The repetitive processes are performed all over the video contents until the user requests a reproduction change.
