摘要： A method of controlling adaptive HTTP streaming of media content between a HTTP server and a HTTP client in a communication system, in which system media content is arranged as a plurality of periods, and each such period comprises a plurality of representations of media segments, which method includes the steps of providing (S10) temporal alignment information for the media segments of the plurality of representations, which temporal alignment information provides indications about a temporal relation between the segments of the plurality of representations of the media content. Further, the method includes providing (S20) key frame location information for the media segments, which key frame location information provides indications about locations of key frames in the media segments of the plurality of representations. Finally, controlling (S30) adaptation of the HTTP streaming of the media content based on at least one of the provided temporal alignment information and the provided key frame location information.

摘要： In a method of video data compression a video frame in a sequence of frames is divided into a number of macroblocks, a particular macroblock being adjacent to a number of previously coded macroblocks including both intra-coded and inter-coded macroblocks. The method includes selecting either a full prediction or limited prediction type in encoding the particular macroblock to provide a corresponding data bit stream, full prediction using both adjacent inter-coded and intra-coded macroblocks, and limited prediction using intra-coded macroblocks only. A signal is provided along with the bit stream to indicate the selected prediction type to a decoder disposed to recover data from the bit stream. The prediction type may be either signaled explicitly, such as by providing a code word in the bit stream, or may be inferred implicitly by selected values or levels of a coding variable.

摘要： A method and apparatus for maximizing the prediction utility of previously encoded macroblocks by adjusting the scanning order of the blocks within a macroblock to be encoded is disclosed. Where no previously encoded blocks are available above the macroblock being encoded, the alternative scanning orders allow for maximum utility of previously encoded blocks located to the left of the macroblock being encoded. Where no previously encoded blocks are available either above or to the left of the macroblock being encoded, the alternative scanning orders allow for maximum utility of information from blocks that are presently being encoded in the same macroblock. The particular scanning order used may be signaled implicitly based on the location of the macroblock being encoded, or it may be signaled explicitly by code words within the bitstream containing the encoded block information. In the case where the scanning order is to be signaled explicitly by a code word, the optimal scanning order may be chosen from among one or more scanning orders for any particular picture and macroblock.
摘要翻译：公开了一种通过调整要编码的宏块内的块的扫描顺序来最大化先前编码的宏块的预测效用的方法和装置。在编码的宏块之上没有先前编码的块可用的情况下，替代扫描顺序允许位于被编码的宏块的左侧的先前编码的块的最大效用。在编码的宏块的上方或左侧没有先前编码的块可用的情况下，替代扫描顺序允许来自当前正在同一宏块中编码的块的信息的最大效用。所使用的特定扫描顺序可以基于被编码的宏块的位置来隐含地发信号，或者可以由包含编码块信息的比特流内的码字显式地发信号通知。在扫描顺序由码字明确地发信号的情况下，可以从任何特定图像和宏块的一个或多个扫描顺序中选择最佳扫描顺序。

摘要： The embodiments of the present invention relate to methods and arrangements for accomplishing trick modes. This is achieved by assigning samples within a track to sample groups, wherein all samples within a sample group belong to one temporal level and by allowing the client to access one temporal level independently of lower temporal levels. In this way, the flexibility for the client regarding play out of different frame rates is increased which can result in a lower bandwidth utilization.

摘要： A multimedia provider (100) generates, based on a request for a media channel from a user terminal (10), a session set-up description that is returned to the user terminal (10). The description defines, when processed in the terminal (10), a session window (20) that is displayed on a screen (12) of the terminal and comprises a region (22) for displaying media data of a requested channel and a channel region (24) comprising information on alternative available media channels. The description also defines a binding between user inputs (14) of the terminal (10) and identifiers of the alternative channels. The set-up description allows for a user-friendly channel switch by automatically transmitting a channel switch request to the multimedia provider (100) upon a triggering of the user input (14) that is associated with the identifier of the requested media channel. The description, thus, provides a visually appealing graphical interface and simultaneously allows for a user-friendly media channel switch.
