Improved B-Picture Coding Scheme for Next Generation Video Compression

B-picture coding in AVS video compression standard

This paper first gives a brief overview of the Chinese audio–video coding standard (AVS) especially on prediction modes of motion compensation for B-picture. Furthermore, two techniques adopted by AVS about how to improve motion compensation for B-picture coding are discussed in detail. The first one is the proposed symmetrical mode that replaces the conventional bi-directional mode, in which o...

Next generation video compression- HEVC

Technologies for Next - Generation Video Coding Standard

1. Trends of HEVC Standardization The target of HEVC standardization is to substantially surpass the compression efficiency of the existing MPEG-4 AVC/H.264 international standard,(1) which currently provides the highest compression performance. The expected complexity of HEVC must be an acceptable level for the hardware technology when supported products are put on the market. In the standardi...

Advances on Video Coding Algorithms for next Generation Mobile Applications

Visual communication via mobile devices is becoming more and more popular. However, current video coding standards are not initially designed for this type of application area. Traditionally, high compression efficiency is usually achieved at the expense of increasing computations. The newest standard, H.264/AVC significantly outperforms the others in terms of coding efficiency, however, the co...

Improved Advanced Motion Vector Prediction Scheme for Surveillance Video Coding

Background frame based video coding achieves a remarkable compress performance for surveillance video coding. In this paper, an improved Advanced Motion Vector Prediction (AMVP) scheme for surveillance video coding is proposed to make Motion Vector Prediction (MVP) more accurate when prediction unit (PU) references background (BG)-frame. Considering the correlations among the spatial PUs, the p...
