Abstract
Rate control plays a significant role for high quality video coding. This paper presents a rate control method for H.264/AVC, using a new bit allocation scheme for both I-frame and P-frame. This scheme is based on our proposed frame complexity measurement and estimation model. The measurement model considers not only the absolute complexity of I-frame and P-frame, respectively, but also the complexity relationship between I-frame and P-frame. Our proposed bit allocation scheme is able to allocate bit rate more efficiently for both I-frame and P-frame in order to achieve a relatively steady visual quality. Experimental results show that our proposed method is capable of providing more stable video quality than other existing methods.
