File formats systems and methods are disclosed that provide a framework that integrates 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. 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.
A computer-readable medium storing data processed from input presentation data, the processed data stored by a method comprising:
A method for storing coded data organized into access layer data units from input presentation data, the method comprising:
A computer-readable medium storing data processed from presentation data, the data stored according to a method comprising:
A computer-readable medium storing coded data organized into access layer data units processed from presentation data, the data stored according to a method comprising:
A computer-readable medium storing coded MPEG-4 data organized into access layer data units processed from input presentation data, the data stored according to a method comprising:
A system for processing coded data organized into access layer data units from input presentation data, the system comprising:
The system of claim 26, wherein the header portion of the segment includes data representing a number of the access layer data units contained in the same object, a size of an access unit, a number of the resynchronization points per an access unit, an average number of resynchronization points per one of the access layer data units, and an access layer data unit table.
A system for processing MPEG-4 data organized into access layer data units processed from input presentation data, the system comprising:
Dependencies are inferred from the claim text.
