According to the present invention, each FGS enhancement layer is assigned a unique dependency identifier and contains only FGS enhancement information. For subsequent enhancement layers, the base dependency identifier for the subsequent enhancement layers will point to either a base-quality layer or an FGS enhancement layer.

    摘要： A system and method for providing improved FGS identification in scalable video coding. According to the present invention, each FGS enhancement layer is assigned a unique dependency identifier and contains only FGS enhancement information. For subsequent enhancement layers, the base dependency identifier will point to either a base-quality layer or an FGS enhancement layer. Alternatively, two base dependency identifiers can be used. One identifier is used to identify the base quality layer, which does not contain FGS information, that is used for the prediction of coding mode and motion information for a subsequent enhancement layer. The other identifier is used to identify the FGS enhancement layer, which contains only FGS information, that is used for the prediction of sample and/or residual data for a subsequent enhancement layer.

    摘要： In the video encoding and decoding of digital video sequence having a prediction operation and an update operation, the update operation includes interpolation to generate energy distributed interpolation. Prediction is carried out on each block based on motion compensated prediction with respect to a reference frame and a motion vector in order to provide a corresponding block of prediction residues. Updating is carried out on a reference video frame based on motion compensated prediction with respect to the block of prediction residues and a reverse direction of the motion vector. The interpolation filter is determined based on the motion vector and the sample values of sub-pixel are interpolated using the block prediction residues by treating the sample values outside the block of prediction residues to be zero. Interpolation is performed along horizontal direction and vertical direction separately using one dimensional interpolation filter.

    摘要： A device, system and method for motion vector prediction in scalable video coding. Embodiments of the present invention may determine a predictive motion vector in scalable video coding by obtaining current layer motion vectors; determining a final base layer motion vector; and calculating a predictive motion vector based on the current layer motion vectors and the final base layer motion vector.

    摘要： Methods, devices, and computer code products for encoding and decoding a video signal including conditional encoding and decoding of a residual prediction flag for an enhancement layer only of all base layers are discrete layers. If some base layers are not discrete, the residual prediction flag is always encoded and decoded. Encoding and decoding the residual prediction flag can include using contexts which depend on whether the reconstructed prediction residual of the discrete base layers is zero or not.

    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： Methods, computer code products and devices for encoding and/or decoding video data in multiple passes, the video data having a multiple components each component including multiple coefficients. The method can starting the next pass of the encoding or decoding process immediately after the end of the current encoding or decoding pass for a given component without regard to whether other components have finished the current encoding or decoding pass. In addition, stagger delays and dampers can be used to more closely regulate the encoding or decoding process to ensure that one component is not encoded or decoded too quickly with respect to other components.

    摘要： An adaptively formed reference block is used for coding a block in a current frame in the enhancement layer. In 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.
