Paper Abstract

In H.264 video coding standard, the combination encoding frame was adopted. It introduces some new algorithms, and modifies several aspects of the encoding scheme. So the encoding scheme improves the encoding efficiency obviously. But the H.264 standard is not supporting FGS encoding. So a H.264 based self-adaptive FGS (Fine Granular Scalable)(H.264-FGS) encoding scheme is proposed in this paper. In this encoding scheme, the base layer of encoder is keeping H.264 encoder architecture, which consists of the motion estimation, motion compensation, intra predictive, integer transformation, loop filtering, content based arithmetic encoding, and etc. In the base layer generated block we obtain base code flux of FGS. Subtracting the original image from the reconstruction image of the base layer, we get the residual error. Then after the DCT transform and the variable length encoding compresses, we obtain the enhanced code flux of FGS. Compared with the original MPEG-4 FGS encoding scheme, the proposed FGS encoding scheme has the feature of increasing encoding efficiency by 1~3 dB and keep the all properties that MPEG-4 FGS encoding technology provided.
