In this paper, we investigate into a new lossless compression framework for video. We are to exploit fuller scale of temporal redundancy, and propose an adaptive optimal compression plane (OCP) determination process to be used with the standard intra-frame lossless predictive coding scheme. The essence of the scheme is to perform the prediction on the plane formed by two axes (among X, Y and T) corresponding to signal correlation evaluation, which enables better prediction (therefore better compression). In spite of the simplicity of the proposed method, simulation results show that the rate saving of the resultant system is 27.0% on average with respect to JPEG-LS, for a large number of videos with different visual content.
