An Efficient MB Layer Rate Control for H.264/AVC Based on Adaptive QP Decision

In the video coding standard a proper quantization parameter decision is very important to increase the coding efficiency with given constraints, such as channel bandwidth and frame rates In this paper; we propose an efficient macroblock layer late control algorithm for H 264/AVC to determine adaptive and precise quantization parameter value First, we suggest it scheme that prohibit early exhaustion of target bits dining the encoding frame Next, we propose a new header bits length estimation algorithm since the bits of the header information occupy a large portion of the total bits due to various macroblock coding modes 264/AVC The simulation results show that, the proposed algorithm provides ail unproved video quality and generates the coding bits close to the target buts
