摘要： The present invention reduces the complexity in the update step without significantly affecting the coding performance. In the update operation in motion compensated temporal filtering for video coding, an interpolation filter is adaptively selected from a short filter and a long filter so that the update signal can be obtained through the interpolation of prediction residue based on the interpolation filter. A short filter refers to a filter with a relatively small number of filter taps such as two. A long filter refers to a filter with a more than two filter taps.

摘要： An adaptively formed reference block is used for coding a block in a current frame in the enhancement layer, hi particular, the reference block is formed from a reference block in base layer reconstructed frame and a reference block in the enhancement layer reference frame together with a base layer reconstructed prediction residual block. Furthermore, the reference block for coding is adjusted depending on the transform coefficients of the base layer reconstructed residual layer. Moreover, the actual reference signal used for coding is a weighted average of a reference signal from the reconstructed frame in the base layer and a reference signal from the enhancement layer reference frame together with a base layer reconstruction prediction residual.

摘要： In scalable video coding where two predictive motion vectors are calculated: one from the current layer neighboring motion vectors and one from the co-located base layer motion vectors. One of the two predictive motion vectors is chosen as the predictive motion vector for current block. A flag bit is coded to indicate which predictive motion vector is chosen only if it is not possible to infer the layer from which the predictive motion vector for the current block comes. Such inference is possible in many situations, such as when both predictive motion vectors are substantially the same, or only one of the vectors is reliable or available.

摘要： A method, program product and device for encoding and/or decoding video data can include treating coefficients in the enhancement layer corresponding to a non-zero coefficient in the base layer differently than a coefficient in the enhancement layer corresponding to a zero coefficient in the base layer. The sign of the base layer quantized coefficient can also be used as it indicates how the reconstructed error differs from the original signal. The coefficient of independent spatial transforms can be arranged into subbands and the encoding of the subbands can utilize spatial information and coded block flags and end of block flags to reduce bit rate. Rather than feeding the coefficients into a context-based adaptive binary arithmetic coding engine on a block-by-block basis, the subbands can be passed into the engine. Subband coefficients may be removed in a controlled manner, leading to a reduced bit-rate.
摘要翻译：用于对视频数据进行编码和/或解码的方法，程序产品和设备可以包括处理对应于基层中的非零系数的增强层中的系数，不同于增强层中对应于基数零系数的系数层。也可以使用基本层量化系数的符号，因为它表示重建的误差与原始信号的差异。独立空间变换的系数可以被排列成子带，并且子带的编码可以利用空间信息和编码块标志以及块标志的结尾来降低比特率。不是按照逐块的方式将系数馈送到基于上下文的自适应二进制算术编码引擎中，而是可以将子带传递到引擎中。可以以受控的方式去除子带系数，导致比特率降低。

摘要： A FGS entropy coding method is suitable for the case when the refinement coefficients at the FGS layer have different prediction from its base layer. When temporal prediction is used in FGS layer coding and the refinement coefficients at the FGS layer have different prediction from its base layer, drift problem may be caused if the FGS layer is partially decoded. Such drift problem may significantly affect coding performance. This new FGS entropy coding method that can solve or greatly alleviate such drift effect and therefore improve coding performance. Three different FGS methods can be used: FGS entropy coding based on spatial frequency location; FGS entropy coding for decoder oriented two-loop structure; and FGS entropy coding with block-confined coding pass.

摘要： Methods, devices, and computer code products for encoding and decoding a video signal involving encoding blocks of the video signal by scan position within a coding cycle in decreasing order to increase the probability that the next symbol will be non-zero. Scalable video decoding techniques can include setting a state variable for a block to a run length if the state variable for the current block is zero otherwise decrementing the state variable if it is not zero. The current coefficient for the block can be set to the terminating value if the state variable is zero otherwise the coefficient can be set to zero if the state variable is not zero.

摘要： This disclosure describes techniques for coding transform coefficients for a block of video data. According to these techniques, a video coder (a video encoder or video decoder) stores a first VLC table array selection table in memory, and an indication of at least one difference between the first VLC table array selection table and a second VLC table array selection table. The video coder reconstructs at least one entry of the second VLC table array selection table based on the first VLC table array selection table using the stored indication of the difference between the first VLC table array selection table and a second VLC table array selection table. The video coder uses the reconstructed at least one entry of the second VLC table array selection table to code at least one block of video data.
