Best Mode for the Invention

Fig . 1 is a block diagram showing an entire structure of an adaptive broadcasting system in accordance with an embodiment of the present invention .

As shown in Fig . 1 , the adaptive broadcasting system of the present invention includes an adaptive broadcasting service providing apparatus 1000 for providing broadcasting contents including an audio/video (AV) program and a package , and an adaptive broadcasting service supporting a synchronizing function and a targeting function , and a user terminal 2000 for consuming an application service such as contents search , selection , acquisition , and consumption by using contents and contents-related metadata from the adaptive broadcasting service providing apparatus 1000 , which are connected to a network including a broadcasting channel/bi-directional IP network .

Fig . 2 is a block diagram illustrating the adaptive broadcasting system in detail in accordance with the embodiment of the present invention.

As shown in Fig . 2 , the adaptive broadcasting service providing apparatus 1000 includes a contents creating unit 100 , a contents service providing unit 200 , a contents searching and navigating unit 300 and a location resolution unit 400 , and the user terminal 2000 includes a user interaction unit 600 and a local storage managing unit 500 , and further includes a contents presenting unit ( not shown ) and a rights managing and protecting unit ( not shown ) , which are not shown in the drawing . Functions of each constituent element are as follows .

The contents creating unit 100 creates an audio/video (AV ) program and a package . A studio, an entertainment company , a Web designer , or a user adaptive contents producer can manage the work .

The contents service providing unit 200 reorganizes contents and metadata , inserts metadata and transmits contents , and a terrestrial , satellite and cable broadcasting companies , Web casters or portal providers can manage the work.

The contents searching and navigating unit 300 is based on broadcasting metadata published in Electronic Program Guide (EPG ) for available contents . A contents searching and navigating function returns a contents identifier (CRID ) of contents selected by a user or automatically selected by a terminal .

The location resolution unit 400 determines a physical location of contents including a channel and broadcasting time from the CRID acquired from the contents searching and navigating unit 300.

The local storage managing unit 500 stores and manages broadcasting contents and metadata . The metadata can be managed in an Extensible Markup Language ( XML ) database ( DB ) or a relational DB . A function connecting the bidirectional metadata between a user and a service provider is based on user history information and user preference information from the user . The user interaction unit 600 drives constituent elements based on a user input signal inputted from an input device of a user terminal , e . g . , a key board, a remote controller , a mouse and a joystick .

The contents presenting unit ( not shown ) provides broadcasting contents and metadata to the user terminal such that a user can use .

The rights managing and protecting unit ( not shown ) protects interface between the constituent elements based on a proper protecting/managing policy ( refer to ETSI TS 102 822-5- 1/2 and ETSI TS 102 822-7 "Bimetadata delivery protection" ) .

The above-mentioned embodiment is an example of the adaptive broadcasting system in a complete bi-directional broadcasting environment . A method for realizing the adaptive broadcasting system is largely divided into two based on a service environment . In a broadcasting environment having a sheer unidirectional broadcasting environment or a narrow-band bi-directional channel , only the contents creating unit and the contents service providing unit among the elements of the adaptive broadcasting system exist in the outside of the user terminal , e . g . , Personal Digital Recorder ( PDR) , and all elements except the contents creating unit and the contents service providing unit makes a user be able to consume desired contents through search, selection, location resolution and acquisition processes in the PDR.

Meanwhile , as described in the above embodiment , in a complete bi-directional broadcasting environment , the contents searching/navigating unit and the location resolution unit as well as the contents creating unit and the contents service providing unit among components of the adaptive broadcasting system can exist in the outside of the PDR . Therefore , the PDR makes a user be able to consume desired contents through search , selection , location resolution and acquisition processes through bi- directional connection to the contents service providing unit or the contents searching and navigating unit by including only the user interaction unit , the contents presenting unit and the local storage managing unit . Fig . 3 is a flowchart describing an adaptive broadcasting service providing process using UED classification schemes in accordance with an embodiment of the present invention .

The adaptive broadcasting service providing process of the present invention basically includes the steps of publication, search, selection, location resolution, acquisition , view and finish .

There are three operation scenarios , which are largely divided based on whether serviced contents are an AV program or package , and whether the serviced package is independent or dependent on the AV program.

Publication

When an AV program is provided, the contents creating unit 100 creates the AV program. The contents service providing unit 200 publishes Content Reference Identifier ( CRID ) for identifying the AV program, attractive metadata of the AV program, schedule information and location resolution data . Herein, the attractive metadata and schedule information of the AV program are described as program information and program location of a TVA-I metadata schema .

The contents service providing unit 200 has a user be able to select an AV program that fits to an environment and preference of the user by publishing user environment and preference , in which the AV program is properly consumed, based on the UED classification schemes in "Targetinglnformation" i . e . , a lower component of the program information . That is , the UED classification schemes of the present invention are provided to the user in the form of the metadata .

When a package to be provided is independent from the AV program, the contents creating unit 100 creates only the package . The package is described based on a TVA-2 package schema and has a user be able to select a component which fits to an environment and preference of the user by publishing the proper user environment , in which each component included in the package can be properly consumed, and preference based on the UED classification scheme in "Targetinglnformation " , which is a lower component of ContentsDescription component .

The contents service providing unit 200 publishes the CRID for identifying the package , the package attractive metadata for inducing package consumption and approximate schedule information of the package . Also, location resolution data for describing when and where the package can be acquired is published . As described above , the attractive metadata and the schedule information of the package are described as the program information (Programlnformation ) and program location ( ProgramLocation ) of the TVA-I metadata schema, just as a general AV program. The contents service providing unit 200 has a user be able to select a package which fits to an environment and preference of the user , by publishing proper user environment , in which the package is properly consumed, and preference by applying the UED classification schemes of the present invention in "Targetinglnformation" i . e . , a lower component of the program information .

Meanwhile , when the package to be provided is dependent on the AV program, the contents creating unit 100 creates an AV program and a package dependent on the AV program. The contents service providing unit 200 publishes the CRID for identifying the AV program, attractive metadata of the AV program, schedule information , location resolution information , link information of the package connected to the AV program. Herein , the attractive metadata and the schedule information of the AV program are described as the program information and the program location of the TVA-I metadata schema, and link information of the package connected to the AV program is described as a "RelatedMaterial " component of the program information of the AV program. The contents service providing unit 200 has a user be able to select an AV program, which fits to an environment and preference of the user , by publishing user environment in which the AV program is properly consumed and preference by applying the UED classification schemes of the present invention in "Targetinglnformation" , i . e . , a lower component of the program information . The homogeneous or heterogeneous contents service providing unit 200 publishes location resolution data for describing when and where the CRID for identifying the package and the package can be acquired .

Search When the AV program is provided, the contents searching and navigating unit 300 provides the attractive metadata and the schedule information of the AV program to the user through the EPG . Also, the EPG provides proper user environment and preference information , in which the AV program can be properly consumed , which were described in "Targetinglnformation" , based on the UED CS of the present invention .

The user grasps the attractive metadata of the AV program such as the title , synopsis and actors of the AV program provided by the EPG , and searches the AV program to be consumed in the contents searching and navigating unit 300 by comparing the proper user environment and preference with the user' s own environment and preference .

When the provided package is independent from the AV program, the EPG provides the package attractive metadata and the package schedule information to the user . Also, the EPG provides the proper user environment , in which the package is properly consumed, and preference information , which were described in "Targetinglnformation" , based on the UED classification schemes of the present invention .

The user grasps the package attractive metadata such as the package title , synopsis and actors of the AV program provided by the EPG, and searches the package to be consumed by comparing the proper user environment and preference with the user' s own environment and preference .

When the provided package is dependent on the AV program, the EPG provides link information of the package connected to the AV program along with the attractive metadata and the schedule information of the AV program. Also , the EPG provides the proper user environment , in which the AV program is properly consumed, and preference information , which were described in "Targetinglnformation", based on the UED classification schemes of the present invention . The user grasps the attractive metadata of the AV program such as the title, synopsis and actors of the AV program provided by the EPG , and searches the AV program to be consumed by comparing the proper user environment , in which the AV program can be properly consumed, and preference with the user' s own environment and preference .

When the user searches the AV program or uses the program through the EPG, the user acquires information on the package connected to the AV program.

Selection

In case of an AV program, when the user selects an AV program preferred by the user in the EPG, the user acquires the CRID of the AV program from the contents searching and navigating unit 300. When the provided package is independent from the AV program, the user acquires the CRID of the package when he selects the package preferred by the user in the EPG .

When the provided package is dependent on the AV program and the user selects the AV program out of preference in the EPG , the user acquires the CRID of the package connected to the AV program from a

"RelatedMaterial " component of the program information of the AV program.

Location Resolution

Both of the AV program and the package acquire physical location information of a real AV program and the package provided by the location resolution unit 400 through a location resolution mechanism from the CRID . The local storage managing unit 500 selects any one location among a plurality of contents locations including both channel and time informations to prevent collision during recording .

Acquisition

An AV program or a package is acquired based on the selected location information including both channel and time informations .

When a package is acquired, the user grasps attractive metadata of each component included in the package , and automatically or semiautomatically selects the entire or part of components to be consumed by comparing a proper user environment, in which the components can be properly consumed, and preference information which were described in "Targetinglnformation, " i . e . , a low-order element of the "ContentDescription, " based on the UED classification schemes of the present invention with the user' s own environment and preference .

When components are selected, physical location information providing an actual component from the location resolution unit 400 is acquired from the CRID of each component through a location resolution mechanism.

View When an AV program is acquired , the AV program is outputted into a user screen such that the user can use the AV program. When a package is acquired, the package is provided to the user after all components selected by the user are acquired and screens are formed by using spatial/temporal relation information between components such that the user can use the package or the AV program.

Finishing

The AV program and package usage history information of the user is stored in a terminal and used to extract user preference .
