Abstract

The ATSC standard for digital television broadcast specifies a data Channel in addition to the normal audio and video channels. A methodology is provided for using the ATSC data Channel to broadcast MPEG-4 video streams, for which a new video service is created. The MPEG-4 streams can be encapsulated into MPEG-2PES (Packetized Elementary Streams) packets or directly into MPEG-2 transport packets. These mechanisms enable the synchronous broadcast of MPEG-4 streams for an ATSC digital TV system without a change to the ATSC standard when data casting. In a system for transmission of video and audio information, in which the system is constrained to operate pursuant to a given standard, including application of a given coding methodology, transmission of the information using a coding methodology that is independent of the coding methodology is provided through encoding the information into a plurality of increments (310) encoded according to the independent coding methodology; and encapsulating the encoded information increments into a payload portion (324) of transmission packets established according to the given standard.
