Abstract
In this paper, a bit-rate estimation method is proposed, which could improve the performance of the H.264 encoder and avoid the strict data-dependencies of mode decision. After that, an efficient parallel algorithm for H.264 encoder with CABAC entropy coding is presented based on the Macro-Block Region Partition (MBRP) parallel method and the bit-rate estimation technique. Simulation results show that, the proposed parallel algorithm could improve the performance of H.264 encoder efficiently while maintaining the similar RD performance as JM 10.2.
