Intra/Inter Algorithm for B Frame Processing in H.264/AVC Encoder

The H.264/AVC video coding standard aims to enable significantly improved compression performance compared to all existing video coding standards. In order to achieve this, a robust rate-distortion optimization (RDO) technique is employed to select best coding mode. This paper presents combined (intra and inter prediction) fast mode decision algorithm for H.264/AVC. The objective is to reduce the computational complexity of the encoder without significant rate-distortion performance degradation. The choose method reduces the computational time savings for B picture up to 42 %, when using modification H.264/AVC encoder with negligible loss of rate-distortion performance.
