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： Methods and arrangements for compression and de-compression of N-stream multi- view 3D video in data handling entities, e.g. a data providing node and a data presenting node. The methods and arrangements involve multiplexing (802) of at least some of the N streams of the N-stream multi-view 3D video into one pseudo 2D stream, which appears as a 2D video stream to a 2D encoder. Further, the pseudo 2D stream is provided (804) to a replaceable 2D encoder, for encoding of the pseudo 2D stream, resulting in encoded data having a 2D codec format. This codec-agnostic modular approach to 3D compression and de-compression ensures a fast and convenient access to flexible virtual 3D codecs for handling of N-stream multi-view 3D video.

摘要： 18 ABSTRACT Co-processing of a video frame (32) and its associated depth map (34) suitable for free viewpoint television involves detecting respective edges (70, 71, 80, 81) in the video frame (32) and the depth map (34). The edges (70, 71, 80, 81) are aligned and used to identify any pixels (90-92) in the depth map (34) or the video frame (32) having incorrect depth values or color values based on the positions of the pixels in the depth map (34)or the video frame (32) relative an edge (80) in 5 the depth map (34) and a corresponding, aligned edge (70) in the video frame (32). The depth values or color values of the identified pixels (90-92) can then be corrected in order to improve the accuracy ofthe depth map (32) or video frame (34). (Fig. 3)10

摘要： Multi-view media data is generated by providing encoded media data representative of multiple media views of a media content. Each of the media views (22-28) is associated with a structural priority identifier (36) indicative of an encoding inter-relationship of the media data relative media data of at least another media view(24-28). A content priority identifier (38) is determined for preferably each media view(22-28). The content priority identifier (38) is, in contrast to the structural priority identifier(36), indicative of the rendering importance level of the media data of the media view(22-28). The determination and inclusion of the content priority identifiers(38)provides an improved processing of the media data, for instance in connection with a selective pruning, rendering, and/or protection application of the multi-view media data.

摘要： In video encoding and decoding predictions may be generated by intra-frame prediction. Intra-frame prediction uses reconstructed pixels in a reconstructed frame. Intra-frame prediction is performed by extending the reconstructed pixels into a predicted block using intra-frame prediction modes, each intra-frame prediction mode indicating a direction of the extension. In order to reduce the number of possible intra- frame prediction modes, a subset is selected from a predetermined set of possible intra- frame prediction modes. A subset of intra-frame prediction modes can be created by forming preselection sets of intra-frame prediction modes on the basis of similarity of their associated predicted blocks and selecting a representative intra-frame prediction mode from each preselection set.
