Bit rate control is an important issue for wireless and Internet video streaming. This paper presents a revised rate control scheme based on an improved frame complexity measure. Rate control adopted by both MPEG-4 VM18 and H.264/AVC uses a quadratic rate-distortion (R-D) model that determines quantization parameters (QPs). Classical quadratic R-D model is suitable for MPEG-4 but it performs poorly for H.264/AVC because one of the important parameters, mean absolute difference (MAD), isdoi:10.1109/sips.2004.1363060 fatcat:ln5p6hl42za6de2uscvck2y6ma
