比特率自适应(ABR)算法已经成为视频传输中研究的热点之一。然而,由于5G无线异构网络具有信道带宽波动大、不同网络间差异明显等特点,多终端协同的自适应视频流传输面临着巨大挑战。提出了一种基于深度强化学习的自适应视频流传输控制方法。首先,建立了视频流动态规划模型,对传输码率以及分流策略进行联合优化。由于该优化问题的求解依赖于精确的信道估计,这在信道状态动态变化的网络中很难实现。因此,将动态规划问题改进为强化学习任务,并采用A3C算法,动态决策视频码率和分流策略。最后,根据实测的网络数据进行仿真,与传统的优化方法相比,本文所提的方法较好地提高了用户QoE。
The adaptive bit rate (ABR) algorithm has become the focus research in video transmission.However
due to the characteristics of 5G wireless heterogeneous networks
such as large fluctuation of channel bandwidth and obvious differences between different networks
the adaptive video stream transmission with multi-terminal cooperation was faced with great challenges.An adaptive video stream transmission control method based on deep reinforcement learning was proposed.First of all
a video stream dynamic programming model was established to jointly optimize the transmission rate and diversion strategy.Since the solution of this optimization problem depended on accurate channel estimation
dynamically changing channel state was difficult to achieve.Therefore
the dynamic programming problem was improved to reinforcement learning task
and the A3C algorithm was used to dynamically determine the video bit rate and diversion strategy.Finally
the simulation was carried out according to the measured network data
and compared with the traditional optimization method
the method proposed better improved the user QoE.
