In this case, the scene information authoring unit 123 connects the metadata fragment information to the scene information by xlink based on the metadata information table to reflect the structured metadata information in the scene information. .

An operation and specific embodiments of the above components will be described with reference to FIG. 2.

2 is a flowchart illustrating a method of generating scene information according to an embodiment of the present invention, and a flowchart of a method of generating user-specific scene information.

As shown in FIG. 2, the method for generating scene information according to the present invention may include receiving various media objects including media and metadata, generating a metadata information table by analyzing the received metadata; Authoring or editing metadata fragment information by linking metadata fragment information to scene information based on the generated metadata information table to reflect metadata information to scene information, and authoring or editing Generating and encoding scene information.

Each of these processes will be described in detail with reference to FIG. 2. First, various media objects including media or metadata to be authored or edited are received (201).

When media or metadata is input as described above, it is determined whether the input metadata is metadata structured by Moving Picture Experts Group (MPEG) -7, MPEG-21, TV Anytime, etc. (202). If it is not the structured metadata, the process proceeds to the process of authoring or editing the scene information (205). If the structured metadata is analyzed (203), the metadata is generated by generating the metadata information table (204). Proceed to the process.

In this case, the generated metadata information table includes metadata types included in the input metadata as shown in Table 1 below, metadata file location information and metadata files including corresponding information for each metadata type. Include location information on the metadata fragment in which the actual information exists. In this case, the location information on the metadata fragment uses a method of describing the location information of the fragment in the XML file, such as an Xpath.

Metadata types Location information Broadcast date and time information
Actual program file location and file name
Program title
Program details
Summary
-Ratings
- Characters
- genre
-Representative photo
... File location information that actually contains the metadata information
ex) www.etri.re.kr/ProgramGuideInfo.xml
Location information for metadata fragments described in the form of xpaths;
ex) // item [3] / Descriptor [1] / Statement [1] / CreationInformation / Title [2] / text ()

Subsequently, the scene information for providing program guide information is authored or edited based on the input media (205).

In this case, it is determined whether the structured metadata information is reflected in the scene information (206). If the metadata information is not reflected in the scene information, the process proceeds directly to step "209", and the metadata information is reflected in the scene information. In this case, metadata and scene information are linked by inserting metadata location information into scene information using xlink based on the metadata information table (207).

In addition, based on the metadata information table, items (metadata information) that can be selected by the user of the consumer terminal so that the user terminal (consumer terminal) can reconfigure the scene according to the user's taste (reorganize the screen to the user's preference). Reflected in the scene information (208). For example, in the case of the UI content authored as described above, the user of the consumer terminal may be set such that a rating and a summary of the program detailed information are not displayed on the user's own terminal screen.

Thereafter, when further authoring or editing of the scene information is required, the process proceeds to “201”. When the authoring or editing of the scene information is completed (209), scene information (scene expression information) is generated (210) and the scene information is encoded ( 211).

3 is a configuration diagram of an embodiment of a scene information rendering apparatus according to the present invention, which is a configuration diagram of an apparatus for rendering user-specific scene information.

As illustrated in FIG. 3, the apparatus for rendering scene information according to the present invention extracts scene information from a data receiver 301 for receiving a program stream from an external device and a program stream received through the data receiver 301. The scene information extractor 302 to decode the scene information extracted by the scene information extractor 302, the scene information decoder 303 to generate the scene tree, and the user preference information to reflect the scene tree. Rendering scene information by reflecting the user information analyzer 304 for analyzing user terminal information and the user information from the user information analyzer 304 in the scene tree generated by the scene information decoder 303. It includes a scene information rendering unit 305 for.

In this case, when the scene information rendering unit 305 renders the scene information, the scene information rendering unit 305 determines whether the link information processing module 306 refers to structured metadata or media and processes the link information processing module 306. ).

Operation and specific embodiments of the above components will be described with reference to FIGS. 4A and 4B.

4A and 4B are flowcharts of an embodiment of a scene information rendering method according to an embodiment of the present invention, and a flowchart of a method of rendering user-specific scene information.

4A and 4B, the scene information rendering method according to the present invention may include receiving a program stream, extracting a scene information stream from the received program stream, and decoding the extracted scene information stream. Generating a scene composition tree, analyzing user terminal information and user taste information, reflecting the generated scene composition tree, and rendering the scene composition tree information reflecting the user information.

In this case, the rendering process is performed by determining whether to refer to the structured metadata or the media when xlink exists when rendering the scene composition tree information.

Each of these processes will be described in detail with reference to FIG. 2. First, when a transmitted program stream is received (401), a scene information stream is extracted from the received program stream (402).

Thereafter, the scene information stream is decoded from the extracted scene information stream (403), and a scene configuration tree is generated from the decoded scene information stream (404).

Thereafter, whether the user terminal information exists is determined (405). If the user terminal information does not exist, the process proceeds to "408". If the user terminal information exists, the device information is analyzed (406) and transmitted to the scene composition tree for reflection. (407). For example, a scene description method such as MPEG-4 LASeR (Light Application Scene Representation) can be expressed to compose and render a scene adaptively according to the performance of the user terminal. It can be reflected in the scene information.

In addition, if it is determined whether the user taste information exists (408), if the user taste information does not exist, the process proceeds to "411", and if the user taste information exists, the user taste information is analyzed (409) and transmitted to the scene composition tree for reflection. (410).

Thereafter, the scene configuration tree is interpreted for rendering (411), and it is determined whether xlink exists. As a result of the determination 412, if xlink does not exist, the process proceeds to "418". If xlink exists, does xlink refer to the structured metadata (413)? It is determined whether 416 is referenced.

As a result of the determination (413, 416), if the xlink (xlink) refers to the structured metadata, the structured metadata file is searched for according to the xlink information (414) and the X is retrieved from the retrieved metadata file. According to the link information, metadata fragment information in which actual information exists is obtained (415).

On the other hand, if the determination results 413 and 416 indicate that the xlink refers to the media, the media file is imported according to the xlink information (417).

Thereafter, the scene information is rendered (screen output) (418). Thereafter, when continuing to render the scene information, the process proceeds to step “411”, and when the scene information rendering is to be stopped, the process ends (419).
