    摘要： The invention provides a standardized interface facility for MPEG-4 authoring, bitstream manipulation, editing and interpretation, with associated tools and interfaces to, resulting in coded bitstreams which are easier to test, check and debug while conforming to the MPEG-4 standard. The specified interfaces can also facilitate graceful degradation in the face of decreased resources by allowing editing of bitstreams. The specified interfaces can also allow creation of decodable bitstreams in response to the user requests either directly or indirectly embedded in audiovisual applications, as well as future services. The invention specifies a bitstream input/output package in the Java programming language to facilitates bitstream encoding and decoding of audio-visual media objects, especially when coding uses the MPEG-4 standard. The invention separates fixed length and variable length coding, and allows flexible parsing which offers the potential of optimized implementation as needed to aid real-time or near real-time operation.

    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.

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.
