摘要 本文基于PID控制器提出了一种高效的H.264比特率转码方案.该方案采用简化的像素域级联转码结构,在保证视频重建质量的同时降低了运算的复杂度,然后在图像层引入PID控制器保证了输出比特率与目标比特率一致.实验结果表明:本文提出的比特率转码方案具有较高的比特率转换精度,是一种高效的比特率转码方案. An efficient H. 264 bit rate transcoding scheme based on PID controller, is proposed in this paper. In the scheme, simplified cascaded pixel domain transcoding structure is adopted to reduce the computational complexity while remaining the reconstructed video quality. Furthermore, a PID controller is introduced in the picture layer to ensure the output bit rate consistent with the target bit rate. The experimental results show that, the scheme proposed in the paper can achieve high bit rate accuracy, which is an efficient bit rate transcoding scheme.
