在视频编码中,作者提出了几种基于最大化时空估计MOS (EMOS)的速率控制技术。本文将这些技术扩展到2K240P视频中,并验证了这些技术在2K240P视频中的有效性。实验结果表明,240fps的帧率并不总是必需的,与固定帧率相比,通过自适应控制帧率可以提高视频的整体时空质量。
In video coding, the authors have proposed several rate control techniques based on a maximization of the spatiotemporal estimated MOS (EMOS). This paper extends the techniques to 2K240P videos, and demonstrates effectiveness of these techniques in 2K240P videos. The experimental results indicate that a frame rate of 240 fps is not always necessary, and that the overall spatio-temporal video quality can be improved by adaptively controlling the frame rate, compared with a fixed-frame-rate approach.
