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.

摘要： The invention provides a system and method allowing the adaptation of a nonadaptive system for playing/browsing coded audiovisual objects, such as the parametric system of MPEG-4. The system of the invention is referred to as the programmatic system, and incorporates adaptivity on top of the parametric system. The parametric system of MPEG-4 consists of a Systems Demultiplex (Demux) overseen by digital media integration framework (DMIF), scene graph and media decoders, buffers, compositer and renderer. Adaptations possible with the invention include interfaces in the categories of media decoding, user functionalities and authoring, thus allowing a number of enhanced functionalities in response to use input as well as graceful degradation in response to limited system resources. The invention includes a specification of an interfacing method in the form of an application programming interface (API). Hot object, directional, trick mode, transparency and other interfaces are specified.

摘要： The invention provides a system and method for processing object-based audiovisual information which is capable of flexibly encoding, storing and accessing a variety of data objects. Audiovisual objects, illustratively prepared in MPEG-4 format, are stored onto physical media using file consisting of segments and access layer primary data units (PDUs), which are accessed using index information. The processes of encoding, storing and accessing audiovisual information are decoupled from monolithic storage in a strict linear order, and reordering and other editorial manipulations are possible.

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： In an interactive communication system based on MPEG-4, Command descriptors along with Command Route nodes or Server Routes in the scene description can be used to support application-specific interactivity. Content selection can be supported by specifying the presentation in command parameters, with the command ID indicating that the command is a content selection command. An initial scene can be created with several images and with text that describes a presentation associated with an image. Associated with each image and the corresponding text is a content selection descriptor. When a user clicks on an image, the client transmits the command containing the selected presentation and the server starts a new presentation. The technique can be used in any application context, as generally as HTTP and CGI can be used to implement any server-based application functionality.
