The invention discloses a method for improving the user experience quality of a live video system, and aims to improve the user experience quality in the live video system and reduce time delay whileensuring the video watching quality. Different from existing documents, the method has the advantages that the calculation resources and the wireless spectrum resources which can be obtained are modeled into a random process, and the random process is closer to a real wireless communication environment. A dynamic system is modeled into a Markov decision process, and as the action space and the state space are continuous and multi-dimensional, a traditional reinforcement learning algorithm such as a deep Q learning network and a strategy gradient is relatively low in efficiency and relatively high in difficulty when the problems are processed. Therefore, the invention provides an online Actor-by combining a video stream transcoding strategy, a user scheduling strategy and a resource allocation method. According to the Critic reinforcement learning algorithm, qualification traces are introduced into the Actor part and the Critic part, and the learning process is accelerated. Theoreticalsimulation proves that the performance is obviously better than that of a deep Q learning network, and the convergence speed is faster than that of a strategy gradient algorithm.
