| Abstract(in English) | Rate control scheme is a very important technology of video transmission, especially in CBR. H.264/AVC standard as a joint development of ITU-T and ISO-MPEG supports rate control. In H.264/AVC reference software JM, initial I and P frame of video sequence can not be encoded with rate control. In this paper, we propose QP(quantization parameter) control scheme of initial I and P frame. We compute target bits of initial I and P frame by setting initial value of coding complexity, and decide the value of QP using the relation between actual bits and QP. We evaluate the proposed method by the value of actual bitrate and PSNR. Our method provide better results than JM. |
