Difference between H.265 and H.266

Near the school, this problem may often be asked, so the first to make a summary of the difference between H.265 and H.266 in the end of the H.265 and H.266. Due to time problems, only the techniques with great improvements, some small details are ignored. Division structure H.265 is a quadruple division, and H.266 is a four-tree truck tree and a binary tree division, so many rectangular blocks are present in the division of H.266 (https://blog.csdn.net/cxy19931018//cxy19931018/ Article / details / 81228759). H.266 also adopted in I frame, allowing brightness and chromaticity independent division (https://blog.csdn.net/cxy19931018/Article/details/79614707); 2. Loop filtering Adaptive loop filter (ALF) is added to H.266; 3. Inframe prediction PDPC in H.266 (specific process https://blog.csdn.net/cxy19931018/Article/details/81227699); The LM prediction mode is added to the H.266 (the specific process https://mp.csdn.net/postedit/79383964), but only the LM mode is received, and the reason for MMLM and MFLM take into account complexity, still held Conservative attitude; H.266 For DC mode, only the long side adjacent reconstruction pixels is used to calculate the mean, and the adjacent pixels of the 265 long side and the short side are calculated; In the H.266, the width-angled intra prediction technology is designed, (the specific process https://blog.csdn.net/cxy19931018/Article/details/83832558); A multi-reference frame prediction technology is adopted in H.266 (the specific process https://mp.csdn.net/postedit/83861975); 4. Inter-frame prediction Affine mode is added in H.266, Huawei's technology (specific process https://blog.csdn.net/lin453701006/Article/details/78966112); Add AMVR technology in H.266 (specific process https://blog.csdn.net/jing_xian/Article/details/53312912?locationnum=3&fps=1); ATMVP technology is added in H.266 (specific process https://blog.csdn.net/ze_guo/Article/details/79578544); 5. Transform AMT technology in H.266 (specific process https://blog.csdn.net/lin453701006/Article/details/79026631) 6. Current image reference (add to BMS) The new technology, Tencent, that is, find the most similar block of the current frame to be encoded, calculate a MV, and pass this MV in the code; 7.DMVR, decoding end motion vector derived Brand new technology, specific process (https://blog.csdn.net/lin453701006/Article/details/78972320); Two-way optical (BIO) technology, specific process (https://blog.csdn.net/lin453701006/Article/details/78979324); You can also miss it, add it slowly.
