    摘要: As information to be processed at an object-based video or audio-visual (AV) terminal, an object-oriented bitstream includes objects, composition information, and scene demarcation information. Such bitstream structure allows on-line editing, e.g. cut and paste, insertion/deletion, grouping, and special effects. In the interest of ease of editing, AV objects and their composition information are transmitted or accessed on separate logical channels (LCs). Objects which have a lifetime in the decoder beyond their initial presentation time are cached for reuse until a selected expiration time. The system includes a de-multiplexer (1), a controller (2) which controls the operation of the AV terminal, input buffers (3), AV objects decoders (4), buffers (4′) for decoded data, a composer (5), a display (6), and an object cache (7).

    摘要: A method for producing compressed video signals representative of a sequence of video frames, including the following steps: determining the value of a temporal variation parameter between successive frames, or portions thereof, of the sequence of frames; determining when the temporal variation parameter meets a predetermined criterion and indexing the frame transitions where the criterion is met; and digitally encoding the sequence of frames with relative reduction of the bitrate for at least a portion of the earlier-occurring frame of each indexed transition.

    摘要: An interactive video/multimedia application (IVM application) may specify one or more media assets for playback. The IVM application may define the rendering, composition, and interactivity of one or more the assets, such as video. Video multimedia application data (IVMA data may) be used to define the behavior of the IVM application. The IVMA data may be embodied as a standalone file in a text or binary, compressed format. Alternatively, the IVMA data may be embedded within other media content. A video asset used in the IVM application may include embedded, content-aware metadata that is tightly coupled to the asset. The IVM application may reference the content-aware metadata embedded within the asset to define the rendering and composition of application display elements and user-interactivity features. The interactive video/multimedia application (defined by the video and multimedia application data) may be presented to a viewer in a player application.

    摘要: A method for receiving encoded MPEG-2 video signals and transcoding the received encoded signals to encoded H.264 reduced resolution video signals, including the following steps: decoding the encoded MPEG-2 video signals to obtain frames of uncompressed video signals and to also obtain MPEG-2 feature signals; deriving H.264 mode estimation signals from the MPEG-2 feature signals; subsampling the frames of uncompressed video signals to produce subsampled frames of video signals; and producing the encoded H.264 reduced resolution video signals using the subsampled frames of video signals and the H.264 mode estimation signals.

    摘要: A fundamental limitation in the exchange of audiovisual information today is that its representation is extremely low level. It is composed of coded video or audio samples (often as blocks) arranged in a commercial format. In contrast, the new generation multimedia requires flexible formats to allow a quick adaptation to requirements in terms of access, bandwidth scalability, streaming as well as general data reorganization. The Flexible-Integrated Intermedia Format (Flexible-IIF or F-IIF) is an advanced extension to the Integrated Intermedia Format (IIF). The Flexible-Integrated Intermedia Format (Flexible-IIF) datastructures, file formats systems and methods provide a framework that integrates advanced concepts, such as objects based audio-visual representation, meta-data and object oriented programming, to achieve a flexible and generic representation of the audiovisual information and the associated methods to operate on the audiovisual information.

    摘要: Audiovisual data storage is enhanced using an expanded physical object table utilizing an ordered list of unique identifiers for a particular object for every object instance of an object contained in segments of a data file. Two object instances of the same object in the same segment have different object identifiers. Therefore, different instances of the same object use different identification and the different object instances may be differentiated from one another for access, editing and transmission. The necessary memory required for randomly accessing data contained in files using the expanded physical object table may be reduced by distributing necessary information within a header of a file to simplify the structure of the physical object table. In this way, a given object may be randomly accessed by means of an improved physical object table/segment object table mechanism.

A system and method are disclosed for storing data processed from presentation data. The data is stored according to a method comprising coding input presentation data by identifying objects from within the presentation data, coding each object individually and organizing the coded data into access layer data units. The access layer data units are stored throughout a plurality of segments, each segment comprising a segment table in a header portion thereof and those access layer data units that are members of the respective segment, there being one entry in the segment table for each access layer data unit therein. A plurality of extended segments are also stored, each of the extended segments further comprising one or more of the access layer data units that include protocol specific data, the extended segments each represented by a extended segment header. The data of an accessible object is also stored, including an accessible object header and identifiers of the plurality of extended segments, each of the extended segments being a member of the same object.
