    Call of Duty data compression

    Hello everyone.
    I was thinking on how does call of duty (1,UO,2,4) communicate over the internet, and i came across on some
    kind of "data compression". I was told that it's "huffman coding". So okey, quick google search and i found on
    wikipedia about "huffman tree". It works by making more common characters weight less and opposite (if i
    got it right). So if that is true, how is it sent over to the server by a client and the other way around ?
    You will need a character frequency and by the way, all code is in binary.

    So, simple question. How to compress CoD client data to server-readable data ?
