    Abstract: A method of decoding a slice of video data may include determining two slice reference lists that are associated with the slice of video data and finding a co-located picture that is associated with the slice of video data. The method may also include retrieving two co-located reference lists that are associated with the co-located picture. Two lowest lists for the slice of video data may be calculated by comparing pairs of the two slice reference lists and the two co-located reference lists.

    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。
