ATSC NRT - SG Extensions Version: 1.0 Date: 5/9/2012 Location: http://www.atsc.org/XMLSchemas/nrt/2012/1/SG1.0.xsd Namespace: http://www.atsc.org/XMLSchemas/nrt/2012/1 Information about the use of this schema can be found in ATSC standard A/103 Non-Real-Time Content Delivery available at http://www.atsc.org/ and referenced as [NRT] below. This schema defines XML elements used as extensions to OMA BCAST Service Guide documents, to be used for ATSC NRT-specific content guide information in Mobile DTV broadcasts. Service Guide fragments are expected to consist of XML elements from the OMA Broadcast Services V1.0 Service Guide Fragments namespace (urn:oma:xml:bcast:sg:fragments:1.0), as defined in the schema located (at the time of publication) at http://member.openmobilealliance.org/ftp/Public_documents/bcast/Permanent_documents/OMA-SUP-XSD_bcast_sg_fragments-V1_0-20090212-A.zip with extension elements inserted in a manner consistent with that schema. Specifically, all extensions make use of the wildcard provision within PrivateExt subelements specified in the OMA SG schema, as mandated for Mobile DTV transmissions in ATSC A/153 Part 4. (Note: The ATSC NRT standard also allows the use of certain OMA SG elements not called out in A/153; these are not described in this schema.) Defines the CircularArea element that can be used for receiver targeting. See Section 9.3 of [NRT]. This element is a wrapper for ATSC NRT extensions to OMA BCAST SG Service fragments. It shall only be used inside a PrivateExt element within a Service fragment. Defines the set of NRT extension elements that may be added to Service fragments. See Section 7.2.4.1 of [NRT]. This element is a wrapper for ATSC NRT extensions to OMA BCAST SG Content fragments. It shall only be used inside a PrivateExt element within a Content fragment. Defines the set of NRT extension elements that may be added to Content fragments. See Section 7.2.4.3 of [NRT]. Defines the set of NRT extension elements that may be specified at the service level as default values for content items. See Section 7.2.4.1.4 of [NRT]. Consumption model (NRT service category) used to guide receiver behavior in handling NRT content. See Section 7.2.4.1.3 of [NRT]. Capabilities used by a receiver in presentation of a content item or service. May be used to define a list of essential capabilities (required for meaningful presentation) or a list of non-essential ones, depending on context. See Sections 7.2.4.1.3 and 7.2.4.3.2 of [NRT]. Group of capabilities to be combined with "OR" logic. Receiver storage (in kB) expected to be sufficient for handling of a content item, or of an entire service, depending on context. See Sections 7.2.4.1.3, 7.2.4.1.4 and 7.2.4.3.2 of [NRT]. Indicator of whether auto-update should be offered to the user for a service. See Section 7.2.4.1.3 of [NRT]. Used to point to an adjunct NRT service from another M/H service (idRef is the id attribute of the referenced Service fragment). See Section 7.2.4.1.5 of [NRT]. Expected acquisition time (in seconds), equivalent to the "duration" parameter of DistributionWindow subelement of Schedule fragment. Used for service level default. See Section 7.2.4.1.4 of [NRT]. ID used to group files in a content item. See Section 7.2.4.3.2 of [NRT]. Indicator of availability of updates to a content item. See Section 7.2.4.1.4 and 7.2.4.3.2 of [NRT]. List of URLs identifying Content-Locations of files retrievable from the internet. The attribute all="true" can be used to indicate all files in a content item are available; in this case the element should be empty. See Section 7.2.4.1.4 and 7.2.4.3.2 of [NRT]. Delay (in seconds) between reception of first byte and playback for a progressively downloaded content item. See Section 7.2.4.3.2 of [NRT].
