摘要:
When the same object appearing in a moving picture is divided into a plurality of items of data (access units), search results using meta data is easily displayed. A meta data stream includes two or more access units AUs having an object_id for specifying whether or not objects designated by object region data in two access units AUs are semantically identical, and an object_subid for specifying whether or not the object region data in the two access units AUs are data on the same scene. From the meta data stream, one of a plurality of access units AUs is selected, the access units being determined to be the same objects by the object_id and being determined to be the same scene by the object_subid, and the selected access unit AU is used to search for an object.

An information playback method includes reading out information from an information recording medium storing a stream which includes meta data of a moving picture capable of being played back upon playback of a video content and which is formed of access units as data units capable of being processed independently, and storing initialization information which includes buffer size information that designates a size of a buffer used upon playback of the meta data, and playing back the video content, and playing back the meta data with designating the size of the buffer on the basis of the buffer size information included in the initialization information.
摘要:
This invention can efficiently execute processing that combines a moving picture at a viewer and metadata at the viewer or on a network. Metadata has data that specifies a lifetime, object region data that describes a spatio-temporal region in the moving picture, related attribute information, and the like, and includes one or more Vclick access units which are data units that can be processed independently. Vclick data includes a search table used to access the metadata.

An information playback method includes reading out information from a recording medium storing a stream which includes meta data of a moving picture capable of being played back upon playback of a video content, and which is formed of access units as data units capable of being processed independently, and storing a table which includes playback time information indicating a playback time of meta data, and which includes access position information indicating an access position of meta data, and playing back the video content, and playing back the meta data on the basis of the playback time information and the access position information included in the table.
摘要:
Meta data can efficiently use a buffer, allow random access, and reduce influence of a data loss when a process that combines a moving picture at a viewer and meta data at the viewer or on a network is to be executed. The meta data is formed by including one or more Vclick access units, each of which has data for specifying a lifetime, object region data that describes the spatio-temporal region in a moving image, and a display attribute/action attribute, and is a data unit that can be processed independently.

摘要:
According to one embodiment, video objects to be played back by a method different from an existing playback sequence with respect to contents recorded on a read-only information storage medium are implemented. The medium is configured to store startup information including one or more pieces of playlist information to be played back first when the medium stores an advanced content, and information used to determine which one of the pieces of playlist information is to be adopted.

According to one embodiment, the contents of a DVD video disc can be reproduced by use of reproduction control information realized by a Markup language. It is possible to hold a resource whose life period has elapsed in a cache memory and use the resource again. Therefore, a data access manager, a file cache which temporarily stores a plurality of resources and a navigation manager (including a filecache manager) which processes management information used to manage a plurality of files held in the file cache and controls the data access manager are provided. The filecache manager registers a loaded resource into a first list if the resource lies within the life period and registers the resource into a second list and manages the same if the life period of the resource has expired.
