<p>A communication system including a transmitter (1'), a receiver (2'), and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter (1') to the receiver (2'). The serial link can but need not be a TMDS or TMDS-like link. In typic al embodiments, alternating bursts of encoded video data and auxiliary data are transmitted over each of one or more channels of the link. Other aspects of the invention are transmitters for use in encoding data for transmission ove r a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link. In accordance with the invention, source da ta to be transmitted are encoded using a subset of a full set of code words. Th e subset consist of preferred code words. The preferred words are predetermine d such that each encoded data stream (comprising only preferred words) transmitted over a serial link has a bit pattern that is less susceptible to inter-symbol interference ("ISI") during transmission than is the bit patter n determined by a conventionally encoded version of the same data (comprising not only preferred words but also other members of the full set). Disjoint clusters of code words in the full set are predetermined. Each cluster includes one or more of the preferred words, and optionally also at least on e additional code word that is similar to a preferred word of the cluster in t he sense that is likely to be generated as a result of probable bit errors in transmission, or transmission and decoding, of such preferred word. In some embodiments, the preferred words have serial bit patterns (during transmission) that have fewer contiguous zeros and ones (and thus are less susceptible to ISI during transmission) than do code words in the full set that are not preferred words.</p> |
