Abstract

Abstract For transmitting video data in a block format having predetermined number of pixels in each block arranged in coordinates of a two-dimensional configuration, each block is provided with at least one function of a predetermined degree having respective coefficients corresponding to respective terms thereof and defining a plane or curved surface. Parameters are obtained as the coefficients of the selected function to give a value for each of the pixels by performing the function of the respective coordinates, and such parameters are transmitted for each block. At the receiving side, the coordinates of the pixels contained in each block are generated, and the values of the pixels are determined for reconstructing a video image therefrom by performing on the coordinates the function which corresponds to the received parameters.
