    • A method is disclosed for decomposing a set of even and odd pictures into low-band and high-band pictures respectively in a image decomposing unit, in which the even picture is used by at least two prediction motion compensators on which the output signal of each prediction motion compensator is scaled according to the number of prediction motion compensators. The method includes calculating the high-band picture by subtracting from the odd picture the scaled motion-compensated signals and using the high-band picture in the at least two update motion compensators, the output signal of each update motion compensator being scaled according to the number of update motion compensators. Finally, the low-band picture is calculated by adding the scaled update motion-compensated signals to the even picture.

    • Video images are communicated between two stations using a method for predicting motion uses up to N frames of the video data, where N is a positive integer and each frame is represented as a plurality of image segments. According to one implementation, combined are at least two spatial displaced image segments from previously decoded frames corresponding to time instances on one side of a temporal axis; and the video data is communicated using the spatial displaced image segments along with corresponding delays as side information. Other aspects of the disclosure include combining using a Lagrangian cost function, and an iterative search method to minimize Lagrangian cost function.
    • 使用用于预测运动的方法在两个站之间传送视频图像,该方法最多使用视频数据的N个帧,其中N是正整数,并且每个帧被表示为多个图像段。 根据一个实施方式,组合了来自先前解码的帧的至少两个空间位移图像段,对应于时间轴的一侧上的时间实例; 并且使用空间位移图像片段以及相应的延迟作为副信息来传送视频数据。 本公开的其他方面包括使用拉格朗日代价函数的组合以及用于最小化拉格朗日代价函数的迭代搜索方法。
