1. A method of coding video data, the method comprising:

  • scanning coefficient values of a first video block using a coefficient scan order;

    collecting statistics associated with at least a portion of the coefficient values;

    adjusting the coefficient scan order in accordance with the collected statistics;

    scanning coefficient values of at least one subsequent video block using the adjusted coefficient scan order when the at least one subsequent video block exists in a coding unit of the first video block; and

    entropy coding the coefficient values.
