Abstract

Currently no information about different shots has been used in the H264/AVC video coding standard. This kind of information can help use choose the size of GOPs and finally reduce the bit rate and PSNR fluctuation when video sequences have multiple shots. We developed an MPEG-7 based rate control scheme in H264/AVC standard. Our proposed scheme outperforms the rate control of the H264 AVC significantly in terms of reducing the average bit rate fluctuation (variance) by 7-60% and the average PSNR fluctuation (variance) by 24-90% between shots. It is also applicable in computationally and memory restricted devices since it needs maximum 2 frames buffer space for MPEG-7 descriptor calculation, while the average amount of extra processing is only 5.8% of the total CPU cycles.
