1. A transmitter for transmitting N-bit video over a serial link configured to transmit encoded K-bit words of video data, said transmitter comprising:

  • a subsystem operable in at least one N-bit mode to pack a sequence of N-bit words of video data into a sequence of fragments, where N≠

    K and each of the fragments consists of K bits of the video data; and

    circuitry coupled to the subsystem and having at least one output configured to be coupled to the serial link, wherein the circuitry is configured to generate a sequence of encoded fragments by encoding each fragment in the sequence of fragments and to assert the sequence of encoded fragments to the at least one output, whereby the encoded fragments can be transmitted over the link when said link is coupled to the at least one output, wherein the sequence of encoded fragments is a sequence of groups of the encoded fragments, each of the groups determines a different one of the N-bit words of video data, and the circuitry is configured to assert the groups sequentially to the at least one output, and wherein the N-bit words of video data are asserted to the subsystem at a first rate equal to P of the N-bit words per unit time and the circuitry is configured to assert the sequence of encoded fragments to the at least one output at a second rate that is at least substantially equal to (N/K)P of the encoded fragments per unit time.
