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:
Metadata for an object in video includes first and second pieces of the metadata each including object property information of the object, property identification information for the object property information, and object region information indicating a position of the object in an image. If the second piece is the same as the first piece in a property of the object property information, the property identification information of the second piece is the same as the property identification information of the first piece and the second piece does not include the property in the object property information of the second piece.

A reproducing apparatus comprises a reading portion which reads image information stored in a disk, a reproducing portion which reproduces the image information read by the reader portion, a specifying portion which specifies an object on the reproduced image information, and a display portion which makes a display relating to the object based on extended information associated with the object specified by the specifying portion.
摘要:
A new navigation function is added to a legacy DVD-Video. A player unit plays back recorded contents, that include video contents or AV contents and ENAV contents associated with contents (menu, chapter) of the video contents, from a DVD-Video disc. The video contents of the DVD disc are played back by a video playback engine. The ENAV contents of the DVD disc are played back by an ENAV engine. The ENAV engine controls playback of the ENAV contents and that of the video contents in combination, connection, and/or synchronism with each other according to the played-back contents of the ENAV contents.

A information recording medium on which stream information including images or sound and management information of the stream information are digitally recorded includes a first recording region in which first management information of the management information for use in common in management of each stream information divided every predetermined data amount can be recorded, and a second recording region in which a reference unit of information obtained by adding second management information of the management information for use in management of divided individual stream information to the divided stream information can be recorded.
