Definitions
- the present invention relates to a package identification and location resolution method; and, more particularly, to a method for identifying and resolving the location of a dependent package linked with a main audio/video (AV) and an independent package not linked with the main AV.
- AV audio/video
- broadcasting environments are changing rapidly from a conventional uni ⁇ directional broadcasting reception into more complicated forms such as multimedia, multichannel, and subscription through diverse receiving terminals by linking broadcasting networks with communication networks.
- An increasing number of viewers demand to directly participate in a broadcasting service out of a conventional passive attitude of receiving and watching a broadcasting program by selecting one among a limited number of channels, or to receive and watch a program they want at a desired time.
- the broadcasting environments are developing into more complicated, diversified and personalized forms.
- Customized broadcasting makes it possible for viewers to consume desired broadcasting contents according to their preferences in diverse kinds of terminals more conveniently and efficiently in the complicated and diverse broadcasting environments.
- the customized broadcasting provides customized broadcasting contents suitable for a usage environment including user preference, terminal performance, network characteristics, and natural environment such as time, place and mood of a user.
- TVA-I Phase 1
- TVA-2 Phase 2
- PDR personal digital recorder
- the TVA- 2 extends a consumption environment of the TVA-I where a uni-directional broadcasting channel and a bi-directional network are assumed, shares contents among diverse terminals in a home network environment, provides services such as a targeting that provides contents suitable for diverse user environments, and accommodates not only TVA-I AV contents but also diverse forms of contents as well.
- a package is defined as a set of contents components.
- the components which is a predetermined combination (a set of all or a subset) , provide a consumer with experience and they are intended to be consumed altogether according to requirements for a business model, i.e., RQ001v20. Packages have been simply recognized to be dependent on AV contents.
- packages can be not only dependent packages linked with a main AV but also independent packages not linked with the main AV. Therefore, required is a new method for identifying a package and resolving the location of the package.
- an object of the present invention which is devised to meet the demand, to provide a refined package identification mechanism using a content reference identifier (CRID) and a location resolution method.
- CRID content reference identifier
- a method for identifying a package which includes the steps of: a) using a Content Reference Identifier (CRID) as an identifier for the package, when the package is a dependent package linked with a main audio/video (AV) , and b) using a CRID as an identifier for the package, even when the package is an independent package not linked with a main AV.
- CRID Content Reference Identifier
- a method for resolving a location of an independent package not linked with a main AV which includes the steps of: a) receiving package information metadata using a CRID as a package identifier; b) searching packages displayed to be available on a user terminal based on the package information metadata; c) selecting a desired package among searched packages; and d) acquiring package metadata on the selected package by using the CRID of the selected package.
- a method for resolving a location of a package among a plurality of dependent packages linked with a main AV which includes the steps of: a) selecting a package among the packages; and b) acquiring the package by using an identifier of the selected package, the identifier using a CRID.
- the metadata of the packages are not provided together with metadata of the main AV.
- a method for resolving a location of a package in a plurality of dependent package groups linked with a main AV which includes the steps of: a) selecting any one package group among the package groups; b) acquiring a package group by using an identifier of the selected package group, the identifier using a CRID; and c) selecting and acquiring one package in the acquired package group.
- metadata of the package groups are not provided together with metadata of the main AV.
- the present invention has an effect of supporting TVA-2 service scenarios by suggesting refined package identification and location resolution mechanisms with respect to both dependent package linked with a main audio/video (AV) and independent package not linked with the main AV described by using TVA-I schema.
- AV audio/video
- Fig. 1 is a flowchart describing a package consuming process under diverse conditions.
- Packages can be categorized into dependent packages linked with a main audio/video (AV) or independent packages not linked with the main AV.
- AV audio/video
- the dependent packages linked with the main AV can include supplementary materials, e.g., selectable resource instance of the main AV such as multiparallel streams from another view or web links related to the main AV, images, and games.
- selectable resource instance of the main AV such as multiparallel streams from another view or web links related to the main AV, images, and games.
- the package is regarded as a material in connection with the broadcasting main AV.
- the package is referred to by a ⁇ RelatedMaterialType' element included in program information (Programlnformation) of the main AV.
- program information Programlnformation
- the present invention uses Content Reference Identifier (CRID) as an identifier to identify a dependent package linked with a main AV due to a necessity for a unique identifier for package and a Group of Package (GOP) .
- CRID Content Reference Identifier
- Table 1 shows the main AV referring to a package combined with educational components. It presents an example of a package linked with a main AV and shows that the main AV described by using the ⁇ Programlnformation' element of the TVA-I is linked with a package having an ⁇ crid: //www. imbc. com/educational_packagel' identifier. Detailed description metadata on the package having the ⁇ crid: //www. imbc.com/educational packagel' identifier are described by using a ⁇ Container' which is a low-rank element of the ⁇ PackageTable' element defined in the TVA-2.
- the packages can be identified.
- Table 2 shows an example of a program having a program identifier ⁇ crid: //www. imbc.com/newsnonstopl03040700704' and two related packages. It shows that the main AV described by using the ⁇ ProgramInformation' element of the TVA-I includes a package having an identifier
- independent packages not linked with the main AV e.g., a Linage game and a city tour guide package
- a CRID as a package identifier due to necessity for a unique identifier for package update and GOP.
- Table 3 shows an independent package having educational components. This is an example of a package not linked with a main AV. It shows attractive metadata for a package composed of a package identifier and a package title provided to a user by using the ⁇ PackageInformation' element of the TVA-2.
- Detailed description metadata for a package having an identifier ⁇ crid: //www. imbc.com/FrenchLearning_package' are described by using a low-rank element ⁇ Container, ' which is a low- rank element of the x PackageTable' element, which is defined in the TVA-2.
- Table 4 summarizes a method of consuming subordinate packages linked with the main AV under diverse conditions
- Fig. 1 is a flowchart for consuming the packages under diverse conditions.
- Both levels 1 and 2 show packages linked with the main AV and package metadata provided with the metadata of the main AV.
- one package is linked with the main AV, which is shown in Table 1 and package metadata are provided with the metadata of the main AV.
- step Sl when one package linked with the main AV is searched and, at step S2, components that fit to a usage environment are selected by a user among a plurality of components that belong to the package.
- steps S3 and S4 the selected components are acquired by a location resolution mechanism extended from the TVA-I using component CRID and, at steps S5 and S6, consumed by the user. The selection and acquisition are carried out once.
- the location resolution mechanism extended from the TVA-I is acquired by extending the doctrine resolution mechanism of the TVA-I.
- the location resolution mechanism of the TVA-I is formed of a location analysis process and an acquisition process using CRID of selected contents
- the location resolution mechanism extended from the TVA-I is formed in the same method as the TVA-I location resolution mechanism but with a difference only in the subject, which is a package group, package or component.
- a plurality of packages or one package group (GOP) is linked with the main TV, and metadata for the packages or the package group are provided with the metadata of the main AV.
- a plurality of packages or one package group linked with the main AV is searched and, at the step S2, one package is selected by the user and components that fit to the user environment are selected out of the components that belong to the selected package.
- the package and the component are selected in the same selection step.
- the selected components are acquired through the location resolution mechanism extended from the TVA-I by- using the component CRID and, at the steps S5 and S6, the acquired components are consumed by the user.
- the selection and the acquisition are carried out once.
- one or more package groups (GOP) are linked with the main AV and package metadata are not provided with the metadata of the main AV.
- a plurality of packages are linked with the main AV and the package metadata are not provided with the metadata of the main AV.
- a plurality of packages linked with the main AV are searched and, at the step S2 to S4, one package is selected by the user and acquired through the location resolution mechanism extended from the TVA-I by using a package CRID.
- the package acquisition using the package identifier is carried out by figuring out an actual locator of a package through location analysis from the identifier of the selected package and acquiring package metadata in the location. Since a component needs to be selected at the step S5, a component pre-stored in a local storage is consumed by going through the location resolution process of the steps S2 to S4 at the steps S5 and S6. The selection and the acquisition are performed twice.
- one or more package groups are linked with the main AV, and metadata for the one or more package groups are not provided with the metadata of the main AV.
- one or more package groups linked with the main AV are searched and, at the steps S2 to S4, one package group is selected by the user and acquired through the location resolution mechanism extended from the TVA-I. Since the package selection is necessary at the step S5, the package is acquired by going through the location resolution process again at the steps S2 to S4. Since a component selection is necessary at the step S5, the location resolution process is carried out again at the steps S2 to S4 and a component pre-stored in the local storage is consumed at the steps S5 and S6. The selection and acquisition is carried out three times.
- a plurality of packages or package groups are linked with the main AV, and package metadata are not provided with the metadata of the main AV.
- package metadata are not provided with the metadata of the main AV.
- After one package is acquired through the location resolution mechanism of the level 3 or 4, and then components that fit to the user environment selected by the user among the components of the package.
- the selected components are acquired by the location resolution mechanism extended from the TVA-I and consumed by the user.
- the selection and the acquisition are carried or twice or three times according to the kind of package.
- CRID of the acquisition step of Table 4 can indicate a component or a package. If the CRID indicates a component, the package is provided together with the metadata of the main AV and the CRIDs of some components among the components of the package will become the targets of acquisition.
- the CRID indicates a package
- the package metadata are not provided with the metadata of the main AV while the package is linked with the main AV or that the package is independent from the main AV.
- a package can be acquired from the CRID by performing the location resolution mechanism once, and it is possible to acquire components by repeating the location resolution mechanism.
- package information metadata are delivered to a user terminal through a unidirectional broadcast channel or a bidirectional networks based on SP006.
- the package information metadata are attractive metadata on packages such as the package ID, package title, and package synopsis,
- the package information metadata are delivered to the user terminal, the presence of an available package is notified to the user through a user interface such as electronic program guide. Then, at the steps Sl and S2, the user searches and selects a package he wants to consume.
- the user acquires package metadata on the package selected based on the location resolution mechanism extended from the TVA-I by using the package CRID.
- components that satisfy the conditions for a given user environment based on the acquired package metadata are selected automatically manually or by an agent.
- the selected components are acquired and consumed based on the location resolution mechanism extended from the TVA-I by using the package CRID.
- the aforementioned package identification and location resolution mechanism supports main AV-dependent or independent packages with TVA-2 service scenarios very well.
- the examples of the scenarios include ⁇ Non-linear multi- parallel stream A/V service, Service Scenario 6.2.4' using an independent package and ⁇ Broadcast movie trailer' using a package linked with a main AV.
- the location resolution mechanism extended from the TVA-I needs to identify when a CRID indicates a package or a component. To identify this, a flag called 'package/component identifier' is added to a message format of a location resolution table (LRT) of the TVA-I, which is shown in Table 5.
- LRT location resolution table
- a flag called ⁇ related to main AV which indicates whether the package is linked with the main AV, is added to a message format of the location resolution table (LRT) of the TVA-I, which is shown in Table 4.
- Each message shall at least include:
- the targeting mechanism for a box type of packages or a middleware-based package is not needed before the acquisition of a package.
- a targeting mechanism for a box-type or middleware-based item or component that extends a usage environment description e.g., MHP, ACAP, ARIB and the like, or middleware-based packages.
- a data broadcasting standard such as the MHP and the ACAP is fixed with respect to a region, and since the other standards, e.g., standards for the box type, except the fixed standard are not used, a broadcasting service provider already knows the target box type and middleware.
- the package when the package is delivered to a bi ⁇ directional network such as the Internet and the package includes an application program for data broadcasting, the application program should be consumed in the middleware of the data broadcasting.
- the package needs to identify the box type so that the user terminal can select a program according to the box type. This signifies that it needs not add a box-type descriptor to the UED.
- the method of the present invention can be realized as a program and stored in a computer-readable recording medium.
- those of ordinary skill in the art can embody the system for providing a package by using the afore-described package identification and location resolution method, and a user terminal that consumes the package.
