Abstract
A hardware encoder has a bit estimation block to compute an estimated bit size for a Coding Tree Unit (CTU). A CTU bit size limit manager selects quantization parameters for use in quantization. The quantization parameters are selected based upon the estimated bit size to insure that the CTU in coded form will not exceed a CTU bit size limit.
