SYSTEM AND METHOD FOR PROCESSING OBJECT-BASED AUDIOVISUAL INFORMATION

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 into physical media (100) using file(s) consisting of segments and access layer primary data units (PDU's), which are accessed using index information. The processes of encoding, storing, and accessing (210) audiovisual information are decoupled from monolithic storage in a strict linear order, and reordering and other editorial manipulations (220) are possible.
