Abstract
A system for processing a video obtains a prediction table for a reference frame of the video and codes one or more target frames of the video based on the prediction table. The prediction table is a Huffman table of difference values for reference pixels of the reference frame. The difference value for a reference pixel is determined based on an actual value of the reference pixel and a prediction value determined based on respective pixel values of one or more pixels adjacent to the reference pixel. The one or more target frames are coded based on the Huffman table of the reference frame and prediction values of the one or more target frames.
