Patent ID: 7359437

Claim:
A communication system, including: a receiver; a transmitter; and a serial link between the transmitter and the receiver, wherein the transmitter is coupled to receive input data, configured to generate a sequence of selected code words by encoding the input data, and configured to transmit the sequence of selected code words to the receiver over the serial link, wherein each of the selected code words is a member of a robust subset of a full code word set, the input data can be encoded as a conventional sequence of code words of the full code word set, and the sequence of selected code words is less susceptible to inter-symbol interference during transmission over the link than would be the conventional sequence of code words, wherein the input data are auxiliary data, the transmitter is coupled to receive video data and configured to generate a sequence of video code words by encoding the video data, and the transmitter is configured to transmit to the receiver over the serial link a first burst of the video code words followed by a burst of the selected code words followed by a second burst of the video code words, wherein each of the video code words is a member of the full code word set and at least one of the video code words is not a member of the robust subset.
