1. A method for coding data, said method comprising:

  • receiving data;

    initializing a top tree bin structure based on a bit depth of said data, said top tree bin structure comprising a plurality of top tree bins, each of said top tree bins comprising a plurality of top tree symbols;

    splitting any one of said top tree bins into two split top tree bins based on a splitting condition;

    wherein said splitting condition is determined based on pseudo-splitting each of said plurality of top tree bins into a plurality of child top tree bins, said splitting step comprising;

    adding bin information or loss of each one of said plurality of child top tree bins,splitting one of said top tree bins comprising said plurality of child top tree bins that correspond to a minimum increase in bin information or a maximum reduction in loss;

    repeating said splitting step until a terminating condition is reached; and

    generating said desired bin structure using said plurality of top tree bins and said plurality of said split top tree bins;

    coding the date using the desired bin structure.
