Abstract :
Delivering MPEG-4 real-time video over the Internet needs rate control schemes to be employed in both the compression and transport domains. In addition to the rate matching requirement between the two schemes to ensure TCP-friendliness, the demand of smoothness also has significant impact on media quality. We propose an integrated rate control scheme for MPEG-4 video transported by a TCP-friendly rate control (TFRC) protocol. Experimental results show successful integration with relatively low rate variation for video coding. Reduced frame skipping indicates, improved temporal quality while the flickering artifact, possibly caused by rate variation, is decreased through a PSNR test.
