Abstract
A video processing apparatus includes an external storage device, a hardware entropy engine, and a software execution engine. The hardware entropy engine performs entropy processing of a current picture, and further outputs count information to the external storage device during the entropy processing of the current picture. When loaded and executed by the software execution engine, a software program instructs the software execution engine to convert the count information into count table contents, and generate a count table in the external storage device according to at least the count table contents. The count table is referenced to apply a backward adaptation to a probability table that is selectively used by the hardware entropy engine to perform entropy processing of a next picture.
