Patent ID: 7974233

Claim:
A system, comprising: a decoder configured to receive an encoded frame from an encoder via a forward data channel, and to return feedback information regarding the reception of some or all of the encoded frame to the encoder via a feedback channel, wherein the encoder is configured to: receive high resolution data frames from a source, for each high resolution data frame, generate a corresponding encoded modified data frame, responsive to the feedback information received from the decoder, analyze the feedback information to determine which of (i) retransmission of a portion of the encoded frame, or (ii) transmission of the corresponding encoded modified data frame is required, and, transmit either the portion of the encoded frame or the corresponding encoded modified data frame, as appropriate, to the decoder via the forward data channel, otherwise, if retransmission of a portion of the encoded frame or transmission of the corresponding encoded modified data frame is not required, transmit a subsequent encoded frame to the decoder via the forward data channel.
