Abstract:
Video transmission services on wireless networks are extremely severely affected by wireless network packet loss. It cannot meet the high-quality requirements of real-time video services. Traditional remedial measures adopt error recovery strategies such as Negative-ACKnowledge character (NACK), Forward Error Correction (FEC), and Hybrid Automatic Re-peat reQuest (HARQ), these cannot well meet the increasingly stringent needs of users in time-varying networks. This article first analyzes three commonly used anti-packet loss strategies in real-time video transmission, and takes into account the performance effects of different strategies in the aspects of delay, quality, and transmission efficiency. Moreover, we propose an adaptive anti-packet strategy selection algorithm based on the three schemes. We establish a unified system delay model and adopts channel response measures in different link delay performance environments. Experimental results show that the proposed algorithm can dynamically select the optimal anti-packet loss solution more sensitively, and optimize the data transmission efficiency on the premise of ensuring the video quality. © 2021 IEEE.
