    摘要： A method of encoding an input video frame into an encoded video frame comprises the steps of disassembling the input video frame into a plurality of blocks of pixels. For each block being a current block, the method further comprises generating a corresponding predicted block from already reconstructed pixels, generating a residual block by subtracting the predicted block from the current block, generating a reconstructed block from the residual block and the predicted block, and generating the encoded video frame from the residual block The method further entails creating a local structure of reconstructed pixels in a region of the predicted block and aligning the predicted block with the local structure to produce an aligned predicted block, wherein the aligned predicted block is used in the steps of generating the residual block and generating the corresponding reconstructed block.

    摘要： A method (1000) of encoding a video sequence comprising Reference Picture Sets (RPSs) is provided. The method comprises arranging (1001) the RPSs in transmission order in a data structure, such as a Sequence Parameter Set (SPS), determining (1003) whether explicit RPS transmission is used for an RPS of a current picture of the video sequence, and encoding (1004) information indicating an RPS comprised in the data structure to be used for predicting the RPS of the current picture, such as delta_idx_minus1, only if explicit RPS transmission is used. By transmitting delta_idx_minus1 only if explicit RPS transmission is used, and interpreting delta_idx_minus1 to be equal to zero otherwise, a reduced bitrate is achieved. Further, a method of decoding a video sequence comprising RPSs, corresponding computer programs and computer program products, as well as corresponding encoders and decoders are provided.

    摘要： QP control information valid for a block of samples is parsed. A QP to use for the block of samples is derived according to a first QP derivation process independent on the QP control information if residual data of the block of samples is not color transformed and according to a second QP derivation process dependent on the QP control information if the residual data of the block of samples is color transformed. The embodiments thereby decouple QP parameters for blocks of samples that are coded with color transform and those that are coded without color transform. This decoupling achieves better flexibility during encoding and results in better visual quality.
