method and system for reducing the distorting impacts between the symbols in the transmission over a serial line in figure of each word in a cluster of words in a single broadcast received word

摘要

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 typical 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 over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link. In accordance with the invention, source data to be transmitted are encoded using a subset of a full set of code words. The subset consist of preferred code words. The preferred words are predetermined 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 pattern 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 one additional code word that is similar to a preferred word of the cluster in the 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.
