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 scalable video coding method for coding a video sequence (10) results in a bit stream (20} partitionable into two layer representations (201, 2O2) of the video sequence (10). The second layer representation (2O2) has an enhanced resolution compared to the first layer representation (2O1.). The method includes generating (si) predictive coding parameters for the second layer using previously reconstructed pixels (14) in the second layer. The method further includes performing (s2) prediction for the first layer, using the predictive coding parameters and the previously reconstructed pixels (14) in the second layer, to generate a first layer prediction signal. The method further includes generating (s3) a first layer residual, based on the difference between the original image and the first layer prediction signal. The predictive coding parameters and the first layer residual are coded (s4) as the first layer representation (2O1). An encoder (30) and computer program are also provided.

The method comprises identifying allowed distance values of distances between the current block and the previous block. The method further comprises selecting a set of PMV candidates as a subset of the set of previously coded motion vectors that were used for previous blocks having an allowed distance from the current block.

摘要： There is provided a method of managing PMV candidates. The method comprises selecting a set of PMV candidates as a subset of the previously coded motion vectors. The method further comprises assigning a code value to each PMV candidate in the set of PMV candidates. The code values vary in length and are assigned to the PMV candidates in order of expected usage such that the PMV candidate having the highest expected usage has one of the shortest code values.

摘要： A method of reducing blocking artifacts associated with consecutive pixels of a block boundary of an image, such as e.g. a video frame is provided. Pixels values of pixels selected from a first block and at least a neighboring block, being located on opposite sides of a block boundary are evaluated. A first offset for the two pixels of each block located next to the block boundary is calculated, after which the first offset is compared to a first threshold value. If abs[first offset] =first threshold, the respective pixel values of j consecutive pixels from the first block and the respective pixel values of k consecutive pixels from the second block are modified by applying weak filtering or no filtering at all on the respective pixels, where n>0, m>0 n>=j, and m>=k.

摘要： The present invention teaches a filter process used in intra or inter prediction of pixel blocks. A first, optionally interpolation, filter is applied in the first filter process to get filtered, optionally interpolated, pixel values. A differential filter and an adaptive gain are utilized in the second process for improving the prediction performance. The adaptivity of the gain can be made even on block basis, allowing a fine tuning of the pixel prediction and/or a fine tuning of pixel rotation and zooming. Alternatively, a combined one-step filter process using the interpolation filter, the differential filter and the adaptive gain is applied to the pixel values.
