Abstract
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.
