Abstract
With the comparison between the H.261 and H.263,the properities of the low bitrate image sequence coding are discussed in this paper.Test sequences are used to compare the advantages of H.263 over H.261,as well as the coding efficiency of the options in H.263.A video communication system based on H.263 code using Pentium CPU,is introduced.
