    Abstract: To let decoder side motion vector derivation (DMVD) coded blocks be decoded in parallel, decoder side motion estimation (ME) dependency on spatially neighboring reconstructed pixels can be removed. Mirror ME and projective ME are only performed on two reference pictures, and the spatially neighboring reconstructed pixels will not be considered in the measurement metric of the decoder side ME. Also, at a video decoder, motion estimation for a target block in a current picture can be performed by calculating a motion vector for a spatially neighboring DMVD block, using the calculated motion vector to predict motion vectors of neighboring blocks of the DMVD block, and decoding the DMVD block and the target block in parallel. In addition, determining a best motion vector for a target block in a current picture can be performed by searching only candidate motion vectors in a search window, wherein candidate motion vectors are derived from a small range motion search around motion vectors of neighboring blocks.

    Abstract translation: 为了使解码器侧运动矢量导出（DMVD）编码块并行解码，可以去除对空间相邻的重建像素的解码器侧运动估计（ME）依赖性。 镜像ME和投影ME仅在两个参考图像上执行，并且在解码器侧ME的测量度量中将不考虑空间相邻的重建像素。 此外，在视频解码器中，可以使用所计算的运动矢量来计算当前图像中的目标块的运动估计，以通过计算空间相邻的DMVD块的运动矢量来预测DMVD块的相邻块的运动矢量，以及 对DMVD块和目标块进行并行解码。 此外，通过仅在搜索窗口中仅搜索候选运动矢量来执行确定当前图片中的目标块的最佳运动矢量，其中，从围绕相邻块的运动矢量的小范围运动搜索导出候选运动矢量。

    Abstract: Adaptive control can use hierarchical motion estimation (HME) and/or multiple reference motion estimation (MRME) for the motion estimation of current encoding blocks. Both HME and MRME are allowed in the motion estimation to achieve a high coding gain. Control consists of slice level control and macro-block (MB) level control. A slice is one or more contiguous macroblocks. In slice level control, it is decided to use only one reference frame or use multiple reference frames to coding current slice based on the motion vectors obtained in coarse level motion estimation. In MB level control, it is decided to perform MRME or perform HME for the MB and its subblocks based on the coarse level motion vectors of the MB.

    Abstract translation: 自适应控制可以对当前编码块的运动估计使用分层运动估计（HME）和/或多参考运动估计（MRME）。 在运动估计中允许HME和MRME两者实现高编码增益。 控制由片级控制和宏块（MB）级控制组成。 切片是一个或多个连续的宏块。 在片级控制中，决定仅使用一个参考帧或者使用多个参考帧来基于在粗略级运动估计中获得的运动矢量对当前片进行编码。 在MB级别控制中，决定执行MRME或基于MB的粗略级别运动向量对MB及其子块执行HME。
