The thesis proposed rate control technique for offline streaming video encoding based on H.264 standard to enhance the quality of video signal. The technique proposed applies a sliding window rate-control scheme which utilizes statistical information of the future video frames with an adaptive estimation of target bits according to the coding complexities of each frame by using mean absolute difference (MAD). Simulation results show that the H.264 encoder integrated with our proposed algorithm effectively alleviates peak signal to noise ration (PSNR) surges and sharp drops a frame that has high motion or scene change. During the encoding process for streaming video, two requirements need to be considered: the pre-loading time that the video viewers have to wait and the physical buffer-size at the receiver side. By considering both requirements, the video encoded still has better video quality compared to H.264.
