1. A method for achieving an arbitrary average data rate for a variable rate coder, comprising:

  • selecting a first composite rate less than the arbitrary average data rate;

    selecting a second composite rate greater than the arbitrary average data rate;

    calculating a reallocation fraction based on the first and second composite rates; and

    based on the reallocation fraction, reassigning a plurality of frames assigned to a first component rate of the first composite rate to a second component rate of the first composite rate, wherein the second component rate is different than the first component rate.
