摘要： An object with the embodiments of the present invention is to make it well defined 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 a 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.
摘要翻译：具有本发明的实施例的目的是使其从先前解码的图像中很好地定义，以检索用于计算当前图像的POC的值，而不管已经解码了多少时间层。这是通过将解码器使用的当前画面的POC确定为当前画面的语法元素pic_order_cnt_lsb和POC，PicOrderCntMsb的最高有效位的总和来实现的，其中当前画面的PicOrderCntMsb 使用至少一个prevPicOrderCntMsb和prevPicOrderCntLsb导出，并且将prevPicOrderCntMsb设置为等于先前参考图片的POC的最高有效位，其解码顺序具有等于零的层标识，并且将prevPicOrderCntLsb设置为等于解码顺序中先前参考图片的POC的最低有效位具有等于零的层标识。

摘要： The present invention relates to an encoder, a decoder and methods thereof for increasing the coding efficiency. The coding efficiency is achieved by introducing Zscan blocks and scanning the Zscan blocks horizontally, row by row, in the picture e.g. by processing the coding units in a Z-scan order within each Zscan block. The Zscan block size is equal to or smaller than the maxsize of the macroblocks and the Zscan block size is larger than the current macroblock size.

摘要： An object of the embodiments of the present invention is to achieve a robust solution for keeping track of the output order. That is achieved by introducing a set of Allowed POC Values (APV) which is signaled from the encoder to the decoder. In this way the number of allowed POC values will be limited, and in this way there is no risk that the output order is undefined if occasional pictures are lost.
摘要翻译：本发明的实施例的目的是实现用于跟踪输出顺序的可靠的解决方案。这是通过引入一组从编码器向解码器发信号的允许POC值（APV）来实现的。以这种方式，允许的POC值的数量将被限制，并且以这种方式，如果偶然的图像丢失，则不存在未定义输出顺序的风险。

摘要： A method executed in the decoder is provided for determining the resolution of a motion vector specifying a reference block on the basis of the smoothness of pixels in a block, the position of this block being an approximation of the position of the reference block. If the block is considered smooth a first resolution will be accurate, while if the block is considered to be non-smooth, one or more refinement bits will be expected for adaptation at the decoder. A method executed in an encoder, capable of providing pictures to a decoder is also provided, as well as a decoder and encoder configured to execute the described methods.

摘要： An encoded representation (60) of a picture (10) of a video stream (1) is decoded by retrieving buffer description information defining at least one reference picture (40, 42). The buffer description information is used to determine a picture identifier of a reference picture (40, 42), which is compared to picture identifiers of reference pictures (40, 42) stored in a decoded picture buffer (230, 350). If the reference picture (40, 42) is determined to be missing based on the comparison of picture identifiers the layer identifier of the reference picture (40, 42) obtained based on the buffer description information is compared to a layer identifier of the current picture (10) in order to determine whether the missing reference picture (40, 42) has been intentionally removed or is unintentionally lost.

摘要： In a method performed by an encoder according to a first aspect a one-bit flag is signaled, wherein the one-bit flag is associated with a reference picture in a buffer description for the current picture. The one-bit flag is set to explicitly indicate to a decoder if the reference picture should be included in a list of reference pictures or not included in the list of reference pictures. The list of reference pictures indicates which pictures that can be used for decoding the current picture.

摘要： An encoded representation (60) of a picture (10) of a video stream (1) is decoded by retrieving buffer description information identifying a buffer description defining multiple reference pictures (40, 42) of the video stream (1) from the encoded representation (60). A picture identifier of a reference picture (42) is determined based on picture identifier information retrieved from the buffer description for the reference picture (42) and a reference picture preceding the reference picture according to a list order in the buffer description. The determined picture identifier is used to update a decoded picture buffer (230, 350) that stores reference pictures (40, 42) to be used as decoding reference for the picture (10) and/or any subsequent picture (50) of the video stream (1).

摘要： Method of encoding an input video frame into an encoded video frame. The method comprises the steps of disassembling the input video frame into a plurality of blocks of pixels; and for each block being a current block, generating a corresponding predicted block from already reconstructed pixels, generating a residual block by subtracting the predicted block from the current block, and generating a reconstructed block from the residual block and the predicted block, generating the encoded video frame from the residual block, creating a local structure of reconstructed pixels in a region of the predicted block and aligning the predicted block with the local structure to produce an aligned predicted block, wherein the aligned predicted block is used in the steps of generating the residual block and generating the corresponding reconstructed block. A corresponding method for decoding the encoded video frame into a decoded video frame also uses a step of creating a local structure of reconstructed pixels in a region of the predicted block and aligning the predicted block with the local structure to produce an aligned predicted block.
