| Abstract: | In this paper, We discuss the statistical and delta modulationalcharacteristics of picture signal from the angle of encoding picture signalby Delta Modulation(DM) method. The effective bandwidth for transmissionof picture signal is given in it.A DM codec for picture signal is also provided.The DM codec can be used for transmitting picture signal in digital opticalfiber transmission system at low bit rates.We have done some experimentalresearches on DM characteristics of picture signal. Finally the paperprovides the results of picture transmission by using the DM codec. |
