Video compression system with post-processing of bitstream generated by hardware video encoding and associated video compression method

Abstract

A video compression system includes a video encoder and a bitstream processing circuit. The video encoder is hardware that performs hardware video encoding upon frames to generate a first bitstream. The first bitstream is output from an entropy encoding circuit of the video encoder. The bitstream processing circuit performs a bitstream post-processing operation upon the first bitstream to produce a second bitstream that is different from the first bitstream, and outputs the second bitstream as a compression output of the frames.
