摘要： A file reading entity, such as a server or a client, and a method in the file reading entity for handling a fragmented media file provided from a file creating entity during HTTP streaming with adaptive progressive downloading. Once it has been determined that the media file comprise at least one alternative movie fragment, constituting an alternative to an associated movie fragment, one of these fragments is selected, such that is can then be transmitted or played out in a conventional manner. A file creating entity configured to provide a file comprising alternative movie fragments is also provided.

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： Methods and arrangements in a client node and a server node for supporting a decision on decoding and playout of a certain content in the client node. The methods and arrangements relate to the determining, conveying and obtaining of information related to the characteristics (level) required for decoding and playing out the certain media content at a non-regular playout rate. The method and arrangement in the client node further relate to determining, based on the obtained information, which playout rate(s) that is/are supported by the client node in regard of level. The methods and arrangements enable the client node to refrain from decoding and playout of the content at a non-regular rate requiring a level which is not supported by the client node.

摘要： The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). Forward error correction (FEC) redundancy data is pre-calculated for the different source blocks (20; 22; 24) and organized into the container file (1) as different FEC reservoirs (30; 32; 34). The container file (1) also comprises meta data (40; 45) providing an association between the media source blocks (20; 22; 24) and the respective FEC reservoirs (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing and FEC calculation.

摘要： The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). The media source blocks (20; 22; 24) are partitioned into source symbols that can be processed by a forward error correction (FEC) algorithm for generation of FEC redundancy data (70). Information (30; 32; 34) of this source block partitioning is included in the file (1) in addition to the source blocks (20; 22; 24). The container file (1) also comprises meta data (40) providing an association between the media source blocks (20; 22; 24) and the partitioning information (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing before calculating FEC data.

The method comprises the steps of entropy encoding (109) the adaptive filter coefficients (104, 107, 112) into the bitstream (110), whereby a prediction (202) for an instance (204) of the adaptive filter coefficients is determined (201 ) based on at least one of the remaining adaptive filter coefficients (206), a prediction error (205) is determined (203) based on the difference between the instance (204) of the adaptive filter coefficients and the prediction (202), and wherein the step of entropy encoding (109) the plurality of adaptive filter coefficients (104, 107, 112) comprises entropy encoding (109) the prediction error (205) for the instance (204) of the adaptive filter coefficients and entropy encoding (109) the remaining adaptive filter coefficients (206). Further is provided a corresponding method of decoding a bitstream (110) of encoded adaptive filter coefficients into decoded adaptive filter coefficients (116, 118, 120, 123).

摘要： The invention involves collective management of video (30) and audio (40) content in a content provider (100). The video (30) and audio (40) content is available in multiple potential versions (32, 34, 36; 42, 44, 46), e.g. in the form of scalable media (36, 46) or media (32, 34; 42, 44) pre-encoded to fixed bandwidth levels. The video (30) and audio (40) data is associated with bandwidth share information (62, 64, 66) enabling estimation of a respective apportionment of a total available bandwidth to the video (30) and audio (40) content. The provider (100) uses this share information (62, 64, 66) and information of the total assignable bandwidth level for providing a respective video version (32, 34, 36) and audio version (42, 44, 46) from the multiple potential versions (32, 34, 36, 42, 44, 46). This allows for increased user-quality when rendering the video (30) and audio (40) data as optimal video (32, 34, 36) and audio (42, 44, 46) version can be dynamically provided during the media session.
摘要翻译：本发明涉及对内容提供商（100）中的视频（30）和音频（40）内容的集体管理。视频（30）和音频（40）内容可在多个潜在版本（32,34,36; 42,44,46）中获得，例如，以预编码到固定带宽水平的可伸缩媒体（36,46）或媒体（32,34; 42,44）的形式。视频（30）和音频（40）数据与带宽共享信息（62,64,66）相关联，使得能够估计对视频（30）和音频（40）内容的总可用带宽的相应分配。提供者（100）使用该共享信息（62,64,66）和总可分配带宽级别的信息，以从多个网络提供相应的视频版本（32,34,36）和音频版本（42,44,46）潜在版本（32,34,36,42,44,46）。这可以在将视频（30）和音频（40）数据呈现为最佳视频（32,34,36）时提高用户质量，并且可以在媒体会话期间动态地提供音频（42,44,46）版本。

摘要： Supplemental processing information (52, 54) defining post-decoding instructions for processing decoded media content is co-organized in a file (1) together with a pseudo-identifier of a media codec employed for encoding the media content. The co-organization trigger abortion of decoding of the media content by a legacy media terminal (210) that does not recognize the pseudo-identifier but enables decoding of the media content by a media terminal (200) that recognizes the pseudo-identifier to thereby enable post-decoding processing of the decoded media content using the supplemental processing information (52, 54). The co-organization thereby prevents legacy media terminals (210) that cannot use the supplemental processing information from decoding the media content and rendering the media content in a media presentation.

摘要： The invention provides a secondary stream (20) of rich media packets (21, 22, 23) defining scene states of a sub-portion (34) of a scene (30) representable by a primary stream (10) or rich media packets (11, 12, 13). Local random access data defining instructions for enabling creation, when being processed, of a starting state of the scene sub-portion (34) without affecting the scene state of scene portions (32, 36) is provided. The local random access data is packed into at least one rich media packet (21, 23), which is inserted into the secondary stream (20) and transmitted to at least one user terminal (300). The local random access data can be used by terminals (300) for tuning-in to the secondary stream (20) and/ or for error recovery relating to the secondary stream (20).
