文章在F-VBR模型的基础上提出了自适应反馈码率控制算法,通过反馈确定视频编码帧率、编码目标比特率和量化参数,根据视频图像的内容对编码帧进行选择。在实际的视频电话系统Cool-Video中应用了该算法,取得了良好的效果。
Based on the F-VBR model, this paper proposes an adaptive feedback rate control algorithm, which determines the video coding frame rate, the coding target bit rate and the quantization parameter by feedback, and selects the coding frame according to the content of the video image. The algorithm is applied in the actual video phone system Cool-Video, and achieved good results.
