Motion Compensated Error Concealment for HEVC Based on Block-Merging and Residual Energy

We propose a motion-compensated error concealment method for HEVC and implement the method in reference software HM. The motion vector from the co-located block will be refined for motion compensation. Based on the reliability of these MVs, blocks will be merged and assigned with new MVs. The experimental results show both a substantial PSNR gain as well as an improvement in visual quality.

I. Introduction

High Efficiency Video Coding (HEVC) is the latest video coding technology standard. As a joint project of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG), the Joint Collaborative Team on Video Coding (JCT- VC) was formed for HEVC development, and the standard was approved and formally published in 2013. As a successor to H.264/AVC, HEVC promises to reduce the overall cost of delivering and storing video assets without decreasing the quality of experience delivered to the viewer, and two key issues have been a particular focus: increased video resolution and increased use of parallel processing architectures [1].
