為因應未來高解析度及影像串流需求，現行的影像編碼標準H.264/MPEG4 Advanced Video Coding (AVC) 已不敷使用，JCT-VC (Joint Collaborative Team on Video Coding) 在2013年發表下一代編碼標準High Efficiency Video Coding (HEVC)，HEVC提供相較於H.264/MPEG4 AVC更多不同大小的編碼區塊，有更好的壓縮比，但大為提升的計算複雜度。本論文專注在使用GPU來加速HEVC編碼中的動態估計及PU模式選擇。實驗結果顯示，平均而言，可以在-0.001%~0.194%的PSNR損失及3.106%~9.906%的bit-rate增加下，達到15.12~17.62倍的編碼效能提升。
For the request of high resolution and video streaming, the H.264/MPEG4 Advanced Video Coding, aka H.264/MPEG4 AVC, is not adequate for needs. In 2013, Joint Collaborative Team on Video Coding (JCT-VC) published the next generation video coding standard, as called High Efficiency Video Coding (HEVC). HEVC supports more different size of coding block than H.264/MPEG4 AVC, and it leads better video compression ratio and high computation complexity. In the thesis, we focus on using GPU to accelerate the motion estimation and PU mode decision of HEVC encoding. In the experiment, our work can achieve the average 15.12~17.62 times speed-up with 3.106%~9.906% bit-rate increase and -0.001%~0.194% PSNR loss.
