| Abstract: | H,264 is a new protocol of video compression established by ITU-T with the best performance compared with other protocols aiming at real-time vide-communication applications. In this paper, a real time video encoding system of H.264 with TMS320C6416 as its processor is introduced, which mainly includes video forward decoding and conversion, capture buffer management, coding and video stream transmission etc. Some important aspects such as video conversion, memory management, optimization technologies are discussed in detail. |
