摘要： There is provided a method of selecting PMV candidates, wherein each PMV candidate corresponds to a motion vector used for coding of a previous block, said previous block having a distance from a current block. The method comprises identifying allowed distance values of distances between the current block and the previous block. The method further comprises selecting a set of PMV candidates as a subset of the set of previously coded motion vectors that were used for previous blocks having an allowed distance from the current block.

摘要： There is provided a method of managing PMV candidates. The method comprises selecting a set of PMV candidates as a subset of the previously coded motion vectors. The method further comprises assigning a code value to each PMV candidate in the set of PMV candidates. The code values vary in length and are assigned to the PMV candidates in order of expected usage such that the PMV candidate having the highest expected usage has one of the shortest code values.

摘要： The solution presented herein defines from which previously decoded picture to retrieve the values for calculating POC of the current picture regardless of how many temporal layers have been decoded. That is achieved by determining the POC of the current picture, to be used by the decoder, as a sum of a syntax element pic_order_cnt_lsb and most significant bits of the POC, PicOrderCntMsb, of the current picture, wherein the PicOrderCntMsb of the current picture is derived using at least a prevPicOrderCntMsb and a prevPicOrderCntLsb and the prevPicOrderCntMsb is set equal to the most significant bits of the POC of a previous reference picture in decoding order that has a layer identity equal to zero and prevPicOrderCntLsb is set equal to the value of the least significant bits of the POC of a previous reference picture in decoding order that has a layer identity equal to zero.

摘要： A slice granularity representing a hierarchical level for slice boundary alignment in a picture (1) comprising at least one slice (10, 12) of coding units (20-56) is used together with coordinates of the coding units (20-56) in a slice (10, 12) to determine those coding units (30, 46A, 46B, 36) that potentially could constitute an end of a slice (10, 12). Each coding unit (30, 46A, 46B) except one of the determined coding units (30, 46A, 46B, 36) is assigned an end-of-slice flag with a first value, while the one determined coding unit (36) gets an end-of-slice flag with a second value. The end-of-slice flags are used during decoding for identifying the end of a slice (10, 12). The embodiments provide an efficient end-of-slice flag signaling by merely assigning such flags to some of the coding units (30, 46A, 46B, 36) in the picture (1), while other coding units need no associated flag.
摘要翻译：与包括编码单元（20-56）的至少一个切片（10,12）的图像（1）中的用于切片边界对准的层次级别的切片粒度与编码单元（20-56）的坐标一起使用切片（10,12），以确定潜在地可以构成切片（10,12）的末端的那些编码单元（30,46A，46B，36）。除了所确定的编码单元（30,46A，46B，36）之一之外的每个编码单元（30,46A，46B）被分配具有第一值的片断结束标志，而所确定的编码单元（36）获得具有第二个值的片断结束标志。切片结束标志在解码期间用于识别切片的末端（10,12）。这些实施例通过仅向图像（1）中的一些编码单元（30,46A，46B，36）分配这些标志来提供有效的切片标志信号，而其他编码单元不需要相关联的标志。

摘要： Encoder, decoder and methods for intra coding of video. The method in the decoder relates to decoding of an intra coded block IZ having a number N of neighboring blocks CU1-CUN. When at least one block CUk of the number of neighboring blocks is unavailable for intra prediction, pixel values for spatial positions covered by CUk are estimated based on at least one pixel value of at least one of blocks CUk−m and CUk+p within the range [CU1-CUk−1, CUk+1-CUN] of blocks, which is available for intra prediction. Further, the block IZ is decoded, using the estimated pixel values for prediction, thus generating a block Z of pixels. k, m and p are integers, and 1≦k≦N; 1≦m≦k; and 1≦p≦N−k; and N is a positive integer.
