摘要： Methods and arrangements in video encoding and decoding entities. The methods and arrangements relate to the joint encoding of reference information associated with encoded video. The method and arrangement in a decoding entity relate to obtaining (402) a single syntax element associated with an encoded block Be, and identifying (404) a reference mode and one or more reference pictures based on the obtained syntax element. The method and arrangement further relate to-decoding (406) of the block Be based on the identified reference mode and one or more reference pictures, thus providing a decoded block, B, of pixels.

摘要： A slice (3) of a picture (1) is encoded by hierarchically splitting a largest coding unit, LCU, (10) of the picture (1) into multiple smaller coding units, CUs (20, 30, 40). A start of the slice (3) is defined to coincide with the border between a first CU (30, 40B) and a preceding CU (40, 40A) of the LCU (10). Address information is generated that allows identification of the first CU (30, 40B) within the picture (1) by defining the position of the first CU (30, 40B) and the size of the largest possible CU (30) that can occupy this position within the picture (1). The address information is included in a coded representation (50) of the picture (1). The address information enables positioning slice starts also within LCUs (10), which slice starts thereby do not need to be limited between LCU borders.

摘要： A communication device and method for controlling a bit rate when encoding video data that includes a plurality of frames. The method includes partitioning a received current frame into groups of blocks; estimating an energy for a current group of blocks, where the energy of the current group of blocks depends from a same group of blocks in a previous frame; determining a target number of bits for the current group of blocks; calculating a quantization parameter for the current group of blocks of the current frame based on the estimated energy of the current group of blocks and the determined target number of bits for the current group of blocks; and encoding the current group of blocks based on the calculated quantization parameter.

摘要： A method performed by a server of a communication network for making an HTTP media stream accessible to a client is provided. A Media Presentation Description (MPD) is generalized, such that the MPD is provided with at least one period element sequentially arranged according to a media play timeline. Each period element is provided with at least one representation such that at least one of the period elements is provided with at least two alternative representations. Each representation is provided with an ordered sequence of at least one media segment URI. Each media segment URI references at least one media segment of the HTTP media stream. The generated MPD enables a client to select representations and to acquire referenced media segments based on the selected representations.
摘要翻译：提供了一种由通信网络的服务器执行的用于使客户机可访问的HTTP媒体流的方法。广播媒体呈现描述（MPD），使得MPD被提供有至少一个根据媒体播放时间线顺序排列的周期元素。每个周期元素被提供有至少一个表示，使得周期元素中的至少一个被提供有至少两个替代表示。向每个表示提供至少一个媒体段URI的有序序列。每个媒体段URI引用HTTP媒体流的至少一个媒体段。所生成的MPD使得客户端能够基于所选择的表示来选择表示和获取所引用的媒体分段。
