METHOD FOR HEADER COMPRESSION IN A VIDEO CODING

摘要

Header elements are coded by means of a code word table in order to compress data blocks for transmission with header information, whereby a code word is allocated to each of said header elements, or a transition between two serial header elements, which is transmitted instead of the actual header information. A current header information is predicted by using the code words for the corresponding header elements and the code word length selected to be inversely proportional to the probability of occurrence of a header element, determined by statistical evaluation of the header information from preceding data blocks and the code word table for coding the current or a subsequent data block arranged by means of the distribution for individual header elements obtained thus, such that a next most statistically-significant header element is assigned the next shortest code word.
