基于实时视频QoE的优化算法研究
Research on Optimized Algorithm based on Real-time Video
如何提升低延迟视频传输的用户体验质量一直是一个具有挑战性的问题。传统的传输算法由于其已经定义好的规则难以应对实时视频传输中动态的网络环境变化;新兴的基于强化学习的传输算法虽能够提升带宽利用率,但其效果不够稳定。本文通过自注意力机制Non-Local将两类算法进行了深度融合,充分提取了两类算法的特征,并预测出更为合适的行为,以提升用户体验质量。本文研究方法相较于在传输过程中设置固定码率的方法在多方面指标上均有提升,有更为深远的研究意义。
How to improve the QoE (Quality of Experience) of low latency video transmission has been a challenging problem. Due to their defined rules, traditional transmission algorithms are difficult to cope with dynamic network environment changes in real-time video transmission. Emerging reinforcement learning-based transmission algorithms can improve bandwidth utilization, but the performance is not stable enough. In this paper, we deeply integrate the two types of algorithms through the self-attention mechanism Non-Local, which fully extracts the features of both types of algorithms and predicts more appropriate behaviors to improve the QoE. Compared with the method of setting a fixed bitrate in the transmission process, the research method in this paper has improved in various metrics and has further research significance.
