URI pointer system and method for the carriage of MPEG-4 data in an ATSC MPEG-2 transport stream file system
First Claim
1. A uniform resource identifier (URI) pointer method for the referencing of Motion Picture Coding Expert Group 4 (MPEG-4) data resources carried in an American advanced television systems committee (ATSC) Motion Picture Coding Expert Group 2 (MPEG-2) transport stream file system (TSFS), the method comprising:
- receiving an MPEG-2 TS, with a packetized ATSC TSFS organized in a hierarchical structure;
locating a local identifier (lid) URI, embedded in an Initial Object Descriptor (IOD) of the Transport Stream (TS) and providing a binding name and access scheme to the objects in the ATSC TSFS to locate resources in the TSFS selected from a group including a Binary Format For Scenes (BIFS) scene description stream and an object descriptor stream;
in response to the URI, accessing an address;
in response to accessing the address, retrieving MPEG-4 resources from the ATSC TSFS; and
,decoding the MPEG-4 resources.

Abstract
A URI pointer system and method are provided for the referencing of MPEG-4 data resources carried in an American ATSC MPEG-2 TSFS. The method comprises: receiving an MPEG-2 TS, with a packetized ATSC TSFS; locating a URI in the TS; in response to the URI, accessing an address such as a lid or an http address; retrieving MPEG-4 resources from the ATSC TSFS; and, decoding the MPEG-4 resources. Accessed lid URIs provide a binding name and access scheme to the objects in the ATSC TSFS, as a lid URI embedded in an Initial Object Descriptor (IOD) is used to locate resources in the TSFS such as a BIFS scene description stream and/or an object descriptor stream. Receiving an MPEG-2 TS, with a packetized ATSC TSFS, means that MPEG-4 resources are formed in a hierarchical directory structure of BIOP objects including a DSM::ServiceGateway, a DSM::Directory, and a DSM::File.

11. A uniform resource identifier (URI) pointer system for accessing Motion Picture Expert Group 4 (MPEG-4) data from an American Advanced Television Systems Committer (ATSC) Motion Picture Expert Group 2 (MPEG-2) transport stream file system (TSFS), the system comprising:
-
a receiver having an interface for accepting an MPEG-2 Transport Stream (TS) with a packetized ATSC TSFS and a local identifier (lid) URI embedded in an Initial Object Descriptor (IOD) providing a binding name and access scheme to objects in an ATSC TSFS to locate resources in the ATSC TSFS selected from the group including a Binary Format for Scenes (BIFS) scene description stream and an object descriptor stream; an address access unit having an interface to accept the MPEG-2 TS from the receiver, the address access unit locating a URI in the TS, accessing an address, and retrieving MPEG-4 resources from a hierarchical directory in the ATSC TSFS; and
,a decoder having an interface connected to the address access unit for receiving the MPEG-4 resources and an interface for supplying decoded MPEG-4 information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
