CODING OF VIDEO OVER IP-BASED NETWORKS

This paper is developed to study the compression performance of video by using searching method of motion estimation ots and snr scalable coding to enhance the quality of video sample. the work evaluates set of suitable objectives fidelity measures, such as mse, psnr and cr. the model of video coding system is designed to treat the video signal as a cbr and implemented for different video samples rates. the two major components inter and intra frames compression is achieved as an optimal compensation for both quality and cbr. in the same time the basic structure of communication networks which is represented by the transmission control protocol/internet protocol (tcp/ip) model is taken into consideration within the system ber control. the developed system is implemented using visual basic language (ver 6.0) underwindows xp operation systems
