Method and apparatus for transmitting compression video data and decoding the same for reconstructing an image from the received data
First Claim
1. A method of transmitting video data in a block format having a predetermined number of pixels arranged in coordinates of a two-dimensional configuration, comprising the steps of:
- providing each block with at least one of a plurality of functions each being of a predetermined degree and each having respective coefficients corresponding to respective terms thereof and defining a respective surface corresponding to pixel values;
obtaining parameters as said coefficients of one of said functions to give a value of each of said pixels in the respective block by performing said one function of the coordinates of each of said pixels; and
transmitting said parameters for each said block.

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.
