摘要： A system in which encoded data (e.g., encoded video and auxiliary data) are transmitted over a serial 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. Source data to be transmitted are encoded using a subset of a full set of code words. The subset consists of preferred code words. 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 it is likely to be generated as a result of probable bit errors in transmission, or transmission and decoding, of such preferred word. Each preferred word of a cluster is indicative of a single source data value. Each received code word in a cluster is mapped to the source data value determined by each preferred word of the cluster.

摘要： A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, alternating bursts of encoded video data and encoded 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, and methods for sending encoded data over a serial link. In accordance with the invention, the data to be transmitted are encoded using a subset (sometimes referred to as a selected set of code words) of a full set of code words. The selected set of code words is selected such that each stream of encoded data (comprising only such code 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 the selected set of code words but also other members of the full set). In general, the best choice for the selected set of code words selected from a full set of binary code words depends on the particular coding implemented by the full set. Typically, the selected set of code words includes words whose serial patterns (during transmission) have fewer contiguous zeros and ones (and thus are less susceptible to ISI during transmission) than do those code words in the full set that are not selected. In preferred embodiments in which the bits of the selected set of code words are transmitted over a serial link as sequences of rising and falling voltage transitions, the bit pattern of each transmitted stream of the selected set of code words implements DC balancing to limit the voltage drift over time.

摘要： A cable including circuitry for asserting information to a user or external device and a system including such a cable. The cable can include conductors, a memory storing cable data, and circuitry configured to respond to a request received on at least one of the conductors by accessing at least some of the cable data and asserting the accessed data serially to at least one of the conductors (e.g., for transmission to an external device). Other aspects of the invention are methods for accessing cable data stored in a cable and optionally using the data (e.g., to implement equalization). The cable data can be indicative of all or some of cable type, grade, speed, length, and impedance, a date code, a frequency-dependent attenuation table, far-end crosstalk and EMI-related coefficients, common mode radiation, intra pair skew, and other information. The cable can include a radiation-emitting element and circuitry for generating driving signals for causing the radiation-emitting element to produce an appropriate color, brightness, and/or blinking pattern.
