Joint Rate Control for Multiple Sequences coding based on H. 264 standard
The objective of joint rate control is to dynamically distribute the channel capacity among video sequences according to their respective complexities, thus a more uniform picture quality and a more efficient utilization of channel capacity are achieved. Most existing approaches are based on MPEG2 coding platform. This paper presents a novel joint rate control scheme for multiple video sequences coding based on H.264 standard. A novel complexity measure that adapts to the characteristics of H.264 video coding is proposed. Experimental results show that the proposed scheme maintains a good balance in picture quality among the sequences as well as within a sequence
