    Abstract: Methods and systems provide efficient sample adaptive offset (SAO) signaling by reducing a number of bits consumed for signaling SAO compared with conventional methods. In an embodiment, a single flag is used if a coding unit to a first scanning direction with respect to a given coding unit is off. In an embodiment, further bits may be saved if some neighboring coding units are not present, i.e. the given coding unit is an edge. For example, a flag may be skipped, e.g., not signaled, if the given coding unit does not have a neighbor. In an embodiment, a syntax element, one or more flags may signal whether SAO filtering is performed in a coding unit. Based on the syntax element, a merge flag may be skipped to save bits. In an embodiment, SAO syntax may be signaled at a slice level.

    Abstract translation: 方法和系统通过减少与常规方法相比信号SAO消耗的比特数来提供有效的采样自适应偏移（SAO）信令。 在一个实施例中，如果关于给定编码单元的第一扫描方向的编码单元关闭，则使用单个标志。 在一个实施例中，如果不存在一些相邻的编码单元，即给定的编码单元是边缘，则可以节省进一步的比特。 例如，如果给定的编码单元不具有邻居，则可以跳过标志，例如，不发信号。 在一个实施例中，语法元素，一个或多个标志可以发信号通知是否在编码单元中执行SAO滤波。 基于语法元素，可以跳过合并标志来保存位。 在一个实施例中，可以在切片级别发信号通知SAO语法。

    IPC: H04N19/513

    Abstract: An encoder or decoder can perform enhanced motion vector prediction by receiving an input block of data for encoding or decoding and accessing stored motion information for at least one other block of data. Based on the stored motion information, the encoder or decoder can generate a list of one or more motion vector predictor candidates for the input block in accordance with an adaptive list construction order. The encoder or decoder can predict a motion vector for the input block based on at least one of the one or more motion vector predictor candidates.

    Abstract: A filtering system for video coders and decoders is disclosed that includes a feature detector having an input for samples reconstructed from coded video data representing a color component of source video, and having an output for data identifying a feature recognized therefrom, an offset calculator having an input for the feature identification data from the feature detector and having an output for a filter offset, and a filter having an input for the filter offset from the offset calculator and an input for the reconstructed samples, and having an output for filtered samples. The filtering system is expected to improve operations of video coder/decoder filtering systems by selecting filtering offsets from analysis of recovered video data in a common color plane as the samples that will be filtered.
