Patent ID: 7529221

Claim:
A system for digital multimedia broadcasting comprising: a multimedia source for generating a plurality of multimedia signal outputs; a multicast module for generating voice information using Internet Protocol; an error correction module for receiving the multimedia signal outputs and the voice information and generating corrected multimedia information; a de-multiplexer coupled to the error correction module for receiving the corrected multimedia information and generating one or more cellular digital multimedia broadcast (CDMB) data streams; a stream multiplexer for receiving the one or more CDMB data streams and inserting a dedicated signaling information in each of the one or more CDMB data streams, and assembling at least one message capsule into the one or more CDMB data stream for indicating data recipients on a media control access (MAC) layer; and at least one data channel modulator coupled to the stream multiplexer for establishing a dedicated signaling path for the corrected multimedia information based on the one or more CDMB data streams output of the stream multiplexer; wherein the at least one data channel modulator each having a physical layer signaling based on a code-division multiple access (CDMA) or orthogonal frequency division modulation (OFDM) technology for mapping the CDMB data streams into a number of data packets on a forward packet data channel according to a predetermined data format and a MAC protocol between a base station and a mobile station.
