摘要： High efficiency video coding (HEVC) enhancements are described for intra-block copying for reducing motion vector (MV) coding redundancy and enhancing in range extensions (RExt) by selecting a default block mv predictor. In reducing MV data redundancy, the value of MVx and/or MVy can have a baseline at the width (W), or height (H) of the respective block, whereby fewer bits need to be encoded. One embodiment for enhancing RExt provides an improved selection of a default block vector predictor for the first CU performing intra-block copying in a CTU.
摘要翻译：描述了用于块内复制的高效率视频编码（HEVC）增强以通过选择默认块mv预测器来减少运动矢量（MV）编码冗余和增强范围扩展（RExt）。在减少MV数据冗余时，MVx和/或MVy的值可以在相应块的宽度（W）或高度（H）处具有基线，由此需要编码较少的位。用于增强RExt的一个实施例提供了对在CTU中执行块内复制的第一CU的默认块向量预测器的改进的选择。

摘要： An extension to the motion-constrained tile sets SEI message provides functionality to signal all tiles are independently decodable and to signal the ROIs that may have more than one tile per ROI. With this extension, the functionality to redefine any independently decodable region-of-interest in a CVS at a coding tree unit level based on user interactivity is enabled. The extension supports the interactivity utilized in various applications such as interactive Ultra High Definition Television (UHDTV), dynamic high-quality zoom-in application, interactive on-demand, e-learning, smart surveillance and many other applications. Additionally, the temporal MCTS SEI message is able to be used by an encoder for tiled streaming to signal explicitly to the decoder that the decoder need only to display the ROI.

摘要： An enhancement for removing signaling redundancy of base color within multi-stage base color and index map (MBCIM) processing of HEVC for computer generated screen content is presented. Redundancy is removed in response to determining and setting merge flags when neighboring pixels are coded and available. During coding of pixels in the current CU, then color are copied from the neighboring blocks when a merge flag is set, or the pixel is coded as it was previously.

摘要： An encoder/decoder is described using enhanced signaling mechanisms SAO parameters. The various parameters are signaled in various ways according to different embodiments of the invention. In a first embodiment (embodiment A), SAO on / off is decoupled form SAO type coding, with SAO on / off flags being jointly encoded for all color components. The second embodiment (embodiment B), is similar to embodiment A, but modified for application to JCTVC-J0268. In a third embodiment separate signaling is provided for SAO on / off, SAO types BO and EO, and for BO and EO side information (classes or band position). Each of these enhanced SAO signaling mechanisms provide enhanced coding efficiency.

摘要： Syntax changes for SHVC/MV-HEVC coding apparatus and methods are described which improve efficiency. In a first portion, syntax of header signaling position under P or B-slice conditions are described, and a new condition to signal inter-layer prediction layer. A second portion describes use of an inter-layer reference picture set as an alternative to the first portion, and provides an arranged syntax to more efficiently signal inter-layer reference information. In a third portion, an inter-layer sample only prediction and TMVP interaction is described which reduces signaling needs for collocated references syntax.

摘要： Enhanced signaling is provided for video coding using a palette coding mode. In one aspect, the sending of a copy from above flag is skipped for the first row of a coding unit (CU), towards eliminating flag redundancy and to address a CU boundary issue. In a second aspect, an address line repeating pattern issue is overcome by signaling a single copy from above flag, except the first row, despite the fact that multiple runs exist in the row.

摘要： A method and apparatus of using logical mode numbers during both prediction and coding in the bit stream, such as for high efficiency video coders (HEVC). These logical intra mode numbers are sorted based on angle which as a result leads to improved coding designs with fewer and smaller look-up tables, and a small gain in coding efficiency. Furthermore, by using this type of naming, the number of most probable modes (MPMs) can be readily extended since no additional tables are required. The use of three MPMs achieves a larger gain of 0.25% and 0.31% for the AI_HE and AI_LC cases, respectively.
