Efficient Software HEVC to AVS2 Transcoding

P Overview of the Second Generation AVS Video Coding Standard ( AVS 2 )

AVS2 is a new generation video coding standard developed by the AVS working group. Compared with the first generation AVS video coding standard, known as AVS1, AVS2 significantly improves coding performance by using many new coding technologies, e.g., adaptive block partition and two level transform coding. Moreover, for scene video, e.g. surveillance video and conference vid⁃ eo, AVS2 provided...

Efficient HEVC to H.264/AVC Transcoding with Fast Intra Mode Decision

High Efficiency Video Coding (HEVC) standard will soon reach its final draft. To provide the widely deployed H.264/AVC devices with HEVC video contents, transcoding pre-encoded HEVC video into H.264/AVC format is highly necessary. Computational complexity of H.264 hinders real-time transcoding. In this paper, we propose an efficient HEVC to H.264 intra frame transcoder to accelerate the time-co...

Analysis of video quality losses in the homogenous HEVC video transcoding

The paper presents quantitative analysis of the video quality losses in the homogenous HEVC video transcoder. With the use of HM15.0 reference software and a set of test video sequences, cascaded pixel domain video transcoder (CPDT) concept has been used to gather all the necessary data needed for the analysis. This experiment was done for wide range of source and target bitrates. The essential...

Video transrating in AVC and HEVC transcoding

HEVC (MPEG-H Part 2 and H.265) is a new coding technology which is expected to be deployed on the market along with new video services in the near future. HEVC is a successor of currently widely used AVC (MPEG-4 Part 10 and H.264). In this paper, the quality coding gains obtained for the Cascaded Pixel Domain Transcoder of AVC-coded material to HEVC standard are reported. Extensive experiments ...
