Abstract

Abstract

A new video rate control scheme which uses linear source model as content complexity measure of video frames is proposed in this paper to implement bit allocation between frames and rate control over Micro Btocte(MB) level in one frame. Comparing with TM5, simulation results show that the proposed method can improve PSNR obviously and achieve more accurate rate control as well as more smooth objective and subjective visual quality even when scenes change. This algorithm is also applicable in MPEG4 and low rate video coding.
