US 8,046,338 B2 · System and method of organizing data to facilitate access and streaming

Abstract

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.

Dependent claims

A non-transitory computer-readable medium storing computer-readable data processed from input presentation data including identifiable objects, the processed data stored by a method comprising:

individually coding each identifiable object to yield coded data;
organizing the coded data into data units by access layer;
storing the data units within 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 a respective segment, there being one entry in the segment table for each data unit stored therein, wherein the header portion comprises data representing a size of an access unit, a number of resynchronization points per data unit, an average number of resynchronization points per one of the data units, and a data unit table;
and
storing data of an object for access, including an object header and identifiers of a group of layer data units, each data unit of the data units being a member of a same respective object, wherein, the data of the object for access are used to deliver at least one of audio content and video content.
