1. A system comprising:

  • a source display, externally updatable;

    an algorithm database comprising a plurality of image compression algorithms;

    a network connection; and

    a frame transfer engine executing on a computer processor and configured to;

    receive a plurality of updates made to the source display,wherein the plurality of updates comprises at least a first update and a second update;

    store at least the first update and the second update in a queue;

    select, based on a first bandwidth of the network connection, a size of the first update, and sizes and times of updates currently present in the queue, a first image compression algorithm in the algorithm database for current transfer over the network connection;

    process the first update using the first image compression algorithm to obtain a processed first update;

    merge the first update with the second update to obtain a merged update;

    select a second image compression algorithm in the algorithm database for current transfer over the network connection based on a second bandwidth of the network connection, a size of the merged update, and sizes and times of updates currently present in the queue;

    process the merged update using the second image compression algorithm to obtain a processed merged update; and

    transmit the processed merged update to the target computer system via the network connection.
