摘要： A video signal has at least a first signal component corresponding to a first color, and a second signal component, associated with the first signal component and corresponding to a second color. Each signal component is divided into blocks, and each block has one or more encodable units. The encoding of at least one encodable unit of the second signal component is switchable between first and second modes. A method of encoding the signal comprises excluding,for at least one encodable unit of the second signal component, use of the second mode for the encoding of the second- signal-component encodable unit concerned when at least one predetermined condition is satisfied relating to an encoded block or encodable unit of the first signal component that corresponds to the second-signal-component encodable unit concerned.

摘要： Motion vectors of a first reference frame (RefC) are permitted to point to a plurality of further reference frames (Ref0-Ref3). A method of storing the motion vectors comprises, when a block (C2) of the first reference frame has two motion vectors (V2A, V2B) initially, selecting one (V2B) of the two motion vectors, the non-selected motion vector (V2A) not being stored. The selected motion vector (V2B) may be scaled (V2B).This can reduce the motion vector memory size.

摘要： Reference prediction mode values, also referred to as most probable modes or MPMs, usable for encoding or decoding of a prediction mode related to a current coding unit, are derived. First and second reference prediction mode values are derived (S402) from respective prediction modes of at least two neighbouring coding units of the current coding unit. The first and second reference prediction modes are different from one another. A third reference prediction mode value is derived (S403) from the first and second reference prediction mode values. The third reference prediction mode is different from each of said first and second reference prediction mode values. By deriving three MPMs instead of two for comparison with the prediction mode of the current coding block the coding efficiency is improved. This is due to the increase in the probability that the prediction mode of the current coding block corresponds to one of the derived most probable modes.

摘要： A temporal motion vector predictor is includable, together with one or more spatial motion vector predictors, in a set of motion vector predictors for a block to encode of a current frame. A method of determining the temporal motion vector predictor comprises selecting as the temporal predictor one motion vector from among motion vectors in a reference block of a reference frame different from the current frame. The reference block is a block of the reference frame collocated with the block to encode or a block of the reference frame neighboring the collocated block. The selection is based on a diversity criterion for achieving diversity among the predictors of the set. This can reduce the motion vector memory requirements with no or no significant additional coding efficiency penalty. Alternatively, even if the motion vector memory is not reduced in size, coding efficiency improvements can be achieved.
摘要翻译：时间运动矢量预测器可与一个或多个空间运动矢量预测器一起包含在用于编码当前帧的块的运动矢量预测器的集合中。确定时间运动矢量预测器的方法包括从与当前帧不同的参考帧的参考块中的运动矢量中选择一个运动矢量作为时间预测器。参考块是与要编码的块并置的参考帧的块或与并置块相邻的参考帧的块。该选择基于用于在集合的预测器之间实现多样性的分集标准。这可以减少运动矢量存储器的需求，没有或没有显着的附加编码效率损失。或者，即使运动矢量存储器的尺寸没有减小，也可以实现编码效率的提高。

摘要： An image area to encode belongs to a first group of image areas that are to be encoded into an encoding unit which can be decoded independently of any other encoding unit. An encoding method comprises determining (S818) a first set (D819) of motion vector predictors for the image area to encode from motion vectors that are associated with other image areas belonging to the first group of image areas. A second set (D816) of motion vector predictors for the image area to encode is determined (S803) from motion vectors that are associated with image areas belonging to one or more further groups of image areas different from said first group of image areas and that are encoded into one or more further encoding units. A motion vector predictor is selected (S807) from among the motion vector predictors of the first and second sets, and information (D808) representative of the selected motion vector predictor is encoded (S814) in dependence upon the number of motion vector predictors in the first and second sets.
