1. An image data transfer system, comprising:

  • a receiver; and

    a transmitter coupled with the receiver via a plurality of signal lines, wherein the transmitter is configured to;

    receive compressed image data including a compressed image body data and a compression code indicating a compression process used to generate the compressed image data;

    perform a bitwise comparison of the compressed image body data with a portion of a preceding transmission data that was transmitted to the receiver;

    select, based on the bitwise comparison, one of the compressed image body data and a bit-inverted copy thereof; and

    transmit to the receiver a current transmission data, wherein transmitting the current transmission data comprises;

    transmitting the compression code using a first set of one or more signal lines of the plurality of signal lines; and

    transmitting the selected one of the compressed image body data and the bit-inverted copy using a second set of one or more signal lines of the plurality of signal lines,wherein the one or more signal lines of the first set are distinct from the one or more signal lines of the second set.
