摘要： A method of encoding a plurality of adaptive filter coefficients (104, 107, 112) into a bitstream (110). 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： 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： 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).

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： 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.

摘要： A media container file (1) is generated by organizing media data (2; 3) defined by a media track (12) in the file (1). Sub-track information (72, 74) identifying media data portions (4, 5; 6, 7, 8) of the media data (2; 3) is organized for each sub-track of multiple sub-tracks defined in the media track (12). At least one of the sub-tracks is assigned selection information (62, 64) defining a selective processing of the media data portion (4, 5;6, 7, 8) defined by the sub-track in relation to other media data organized in the media container file (1). The media data (2, 3) advantageously relate to layered media or media defining multiple camera views which are organized into sub-tracks (12). The selection information (62, 64) allows selection among tracks (12) and sub-tracks when setting up a media session and switching between tracks (12) and sub-tracks during such a media session.

摘要： An adaptive filter having multiple filter parameters is determined by defining at least one filter parameter as having a first level of adaptivity and defining at least one other filter parameter as having a second, different level of adaptivity. The parameter values for the at least one filter parameter having the first level of adaptivity are determined among a first set of allowable filter parameter values. The parameter values for the at least one filter parameter having the second level of adaptivity are correspondingly determined among a second, different set of allowable filter parameter values. The different levels of adaptivity in the filter parameters of the adaptive filter are achieved as the second set comprises more allowable filter parameter values than the first set. The adaptive filter is advantageously used in filtering in intra or inter predication during video encoding and decoding.
