Description

Apparatus and method for providing advanced EPG service for mobile terminal

The present invention relates to a digital broadcast service, and more particularly, to an apparatus and method for providing an enhanced Electronic Program Guide (EPG) service for a mobile terminal interworking with the broadcast information received from a home server in a home.

Recently, as digital broadcasting services are in full swing, researches on technologies for providing customized broadcasting services in a multi-channel multimedia environment have been actively conducted. As an example, the private international standard TV-Anytime (hereinafter referred to as "TV-Anytime") is a user's preference information based on metadata representing the description information of the content. Is a standard specification for providing an Anytime service that allows a user to store desired content for viewing at a free time by matching the above metadata with the metadata as described above, and in TV-Anytime, MPEG It contains content-based descriptions and EPG (electronic program guide) information as defined in -7, allowing users to easily navigate and select the desired content. Part A defines a format for describing metadata, that is, a schema, and MPEG-7 DDL based on XML (eXtensible Markup Language). Definition Language (ISO / IEC 15938-2) Part B relates to metadata transmission, which is a binary format [MPEG-7 BiM (Binary Format For MPEG-7)] (ISO / IEC 15938-1), It includes fragmentation models, encapsulation, and indexing techniques.

The TV-Anytime metadata will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a schema configuration of a TV-Anytime according to the prior art.

As shown in FIG. 1, the TV-Anytime metadata is an XML document having a root element of “TVAMain” and has subcomponents of CopyrightNotice, MetadataOrignationInformationTable, ClassificationSchemeTable, ProgramDescription, and User-Description.

In the TV-Anytime forum, metadata related to content is defined as content description metadata or instance description metadata for metadata, and metadata related to a user is defined as user metadata. ), Metadata for temporal access and manipulation of broadcast programs is defined as segment metadata.

First, the content description metadata represents content-specific information such as a program title, a storyline, and a genre. The content description metadata is mainly created by a content creator, and the instance description metadata includes content location (broadcast time and channel) and video format. Information required when a user finds a specific instance of desired content, such as a transmission parameter, is generated by a content provider. Therefore, content description metadata and instance description metadata may be used in the process of searching for and selecting content desired by a user.

The user description metadata are used to describe user information, define user preferences and usage histories, and adopt the MPEG-7 Metadata Description Scheme (MDS) standard. The usage history is used to express the user's content consumption form (fast forward, rewind, pause, play, etc.) and may be used to derive user profile information. The user preference is preference information on the genre, time, channel, etc. of the user, and may help the user to easily select the content by filtering the content according to the preference. As such, the user description metadata is metadata that directly enables a personalized broadcast service.

The segment description metadata are intended to describe temporal position information, content information, etc. of a segment referring to a normal scene when one program is composed of a plurality of meaningful scenes based on time, place, content, etc. This allows various processes such as segment level access, playback, replacement, grouping, etc., to reconstruct or recycle the AV stream. Examples include video summaries, book marks, and the like, made up of highlight segments.

In addition, the TV-Anytime Forum according to metadata transmission defines two types of metadata web services for bidirectional metadata services through return paths. Both types can be thought of as well-defined behavior and remote procedures for input and output sets. In the WSDL (Web Service Description Language) standard based on XML (eXtensible Markup Language), the above-described remote procedure is defined in the form of a Simple Object Access Protocol (SOAP) operation. There is a "get_Data" operation for metadata retrieval and a "submit_Data" operation for user description submission. For reference, the aforementioned SOAP protocol is an XML communication protocol that allows access to an object in a distributed environment.

In addition, the request / response types used in the TV-Anytime metadata service are defined in the namespace "urn: tva: transport: 2002", which is a tool for validating various messages. As provided. Types defined in the metadata specification and the content referencing standard are referenced in the transport namespace. Schema fragments are also defined in the aforementioned namespaces, and namespace providers are defined as “tns:” in this schema fragment. The complete XML schema file is tva_transport_types_v10.xsd.

1. get_Data operation

The get_Data operation provides the client with the ability to retrieve TV-Anytime data for the program or program group to the server. The following list illustrates the functions that can be provided by the TV-Anytime metadata provider using the get_Data operation.

First, the operation returns the content reference data for the CRID by using a content referencing ID (CRID) list.

Second, the operation returns the TV-Anytime metadata for the CRID using the CRID list.

Third, the operation receives a query for a particular metadata attribute (genre, actor, etc.) and returns a corresponding program.

Fourth, the operation returns a program in response to a query for a specific time or a specific channel.

Referring to the operation of the get_Data operation, in the TV-Anytime service, the client transmits a SOAP request message (Get_Data () Request) by the get_Data operation to the metadata service server through an IP network. In principle, the get_Data operation supports all query types and provides a wide range of queries for metadata constraints.The metadata service server then queries the SOAP request message by means of a SOAP response message [get_Data () Request]. Return the result.

end. Request Format

As shown in Table 1, in the get_Data operation, the request format specifies three types of parameters to the client, and the element type returned as a query (search) result value to the RequestedTables type.

<element name = "get_Data" type = "tns: get_Data" /> <complexType name = "get_Data"> <sequence> <element name = "QueryConstraints"> <complexType> <choice> <element name = "PredicateBag" type = "tns: PredicateBagType" /> <element name = "BinaryPredicate" type = "tns: BinaryPredicateType" /> <element name = "UnaryPredicate" type = "tns: UnaryPredicateType" /> </ choice> </ complexType> </ element > <element name = "RequestedTables" type = "tns: RequestedTablesType" /> </ sequence> <attribute name = "maxPrograms" type = "unsignedInt" /> </ complexType>

I. Response Format

The response format of the get_Data operation includes zero or one or more XML instance documents for the elements (TVAMain, ContentReferencingTable, InvalidFragments), as shown in Table 2 below, and returns the query result value according to the RequestedTables type requested in the request format. .

TVAMain ContentReferencingTable InvalidFragments

  <element name = "get_Data_Result" type = "tns: get_Data_ResultType" /> <complexType name = "get_Data_ResultType"> <sequence> <element name = "TableSortingInformation" type = "tns: RequestedTablesType" minOccurs = "0" /> <element ref = "tva: TVAMain" minOccurs = "0" /> <element ref = "cr: ContentReferencingTable" minOccurs = "0" /> <element name = "InvalidFragments" type = "tns: InvalidFragmentsType" minOccurs = "0" / > </ sequence> <attribute name = "serviceVersion" type = "unsignedInt" use = "required" /> <attribute name = "truncated" type = "boolean" />

2. submit_Data operation

Table 3 shows a request format and a response format of a submit_Data operation. The submit_Data operation basically transmits only data in which user's personal information is excluded. That is, the Phase I technical standard of TV-Anytime restricts the data defined by the intelligent agent based on the usage service and the content or a set of anonymous profile data generated by manual writing. The TV-Anytime Forum respects and includes the basic rights of all users and providers, which includes the basic rights of the privacy of content users and the legal rights of all participants, such as content creators, providers and service providers.

3. get_Data operation with user information

Currently, in the TV-Anytime, based on the user metadata transmitted through submit_Data, the service agent performs a get_Data operation through a special algorithm for each agent and transmits the result to the user.

As such, the current TV-Anytime metadata server may collect user metadata transmitted through the submit_Data operation and utilize the statistics on content usage.

However, the conventional TV-Anytime is transmitted according to the MPEG-2 system in the case of EPG based on Program and System Information Protocol (PSIP) information, and the data information is poor, so that the terminal having no broadcast reception function receives the corresponding information. This is an impossible problem.

In particular, as the user's mobile interface environment is becoming more diverse day by day, efforts are being made to provide a smooth service so that the user does not feel uncomfortable through various user interfaces.

Accordingly, the present invention has been made to solve the above problems, by converting the broadcasting information such as a large channel, content, advertising, etc. into information suitable for the environmental information of the user terminal to provide a variety of terminals owned by the user broadcast information It is an object of the present invention to provide an improved EPG service providing apparatus and method for a mobile terminal that satisfies a user's desire to watch a video and provides broadcasting information without spatial limitations, thereby increasing satisfaction of a service.
