摘要： The content description of multimedia content contains a plurality of descriptor values that pertain to specific events within the media. A Transport Hint Table (THT) provides a set of synchronization events that indicate the relation between timed events in the media and their representation in the content's description data. The THT allows for synchronized delivery of presentation of content description data with the associated events in the media. The THT provides a set of sync events based on the existence of “time” related events obtained from the content description data, which are relevant to particular events in the media. The THT allows the transport layer encoder to use the time-related events to synchronize the scheduled delivery times of media content segments and their associated descriptions. The THT also provides information for fragmenting a description for delivery and for managing resources at the decoder.

摘要： Updates to a content description represented as a tree are contained in a series of fragment update units. Each fragment update unit includes an update command and a navigation path, and may include a fragment payload depending on the update command. The update command is applied to a set of nodes in the tree that are selected using the navigation path. The fragment payload may contain a fragment, a fragment reference, or an attribute. The update command may be an add, delete or replace command. More than one fragment payload may be present in the fragment update unit, with each fragment payload applied to a different one of the nodes from the set selected by the navigation path.

摘要： A data document is constructed by attaching a set of child nodes, selected from nodes in an existing data document or a document fragment, at an update location, which is a node in the existing data document or the document fragment that is identified by a navigation path. When the update command is a merge, one or mode nodes (“merge nodes”) in the document fragment are identified as update locations, and the nodes in the existing data document are merged as child nodes of the merge nodes in the document fragment. When the update command is a join, a node (“join node”) in the existing data document is identified as the update location, and an ordered list specifies which nodes in the existing data document and which nodes in the document fragment are to be joined as the set of child nodes for the join node. The join and merge update commands, navigation paths, and document fragments may transmitted as a series of fragment update units to construct the data document.

摘要： The encoding and distribution of schema for multimedia content descriptions are described. Before the schema is sent to a system for use, it is encoded by assigning a first token for each component in the schema and a second token for each attribute of each component. In one aspect, a signifier is sent first to signal that the schema is to be sent in a particular format. In one aspect, the schema is sent as a whole entity first. In another aspect, some of the components of the schema are sent first, followed by the schema that refers to these components. In another aspect, the schema is sent first, followed by a set of component types. When the decoder receives the signifier and encoded schema, it looks up values for the first and second tokens in a look up table for all components and attributes to decode the schema.

摘要： An encoding methodology encodes an instance document describing multimedia content by determining a context node in the content description and using a schema associated with the context node to determine the maximum number of children attributes and elements of the context node. Values for required attributes and elements are encoded into required attributes and required elements sections, respectively. Values for each optional attribute and optional element present in the content description are encoded into corresponding optional attributes and optional elements sections. In one aspect, a mask is encoded that indicates which of the optional attributes or optional elements are present in the content description. In another aspect, a count of the optional attributes or optional elements is used in place of the mask. A corresponding decode methodology extracts the values of the attributes and elements from the encoded instance document to re-create the content description.

摘要： Transcoding between content data and description data. The transcoding may include transcoding content data to corresponding description data. Additional description information to complete the description data may be requested. The transcoding may include transcoding description data to content data, including seeking content data items that match the description data. Content data items that best match the description data may be selected and included in the content data. A user may be requested to select items from a group of matching content data items. The content data may be stored according to the Moving Pictures Expert Group-4 (MPEG-4) standard, and the description data may be stored according to the MPEG-7 standard. The transcoding may be achieved via rules stored in the Extensible Stylesheet Transformation (XSLT) format. The transcoding may be implemented on a computing device, such as a personal computer.
