摘要：
In order to solve the problem of the high requirements of data transmission rate and sensitivity to transmission delay in virtual reality (VR) based on cloud services, a Cloud VR system with MEC (mobile edge computing) was proposed, mainly including viewpoint-based VR processing and HDA (hybrid digital-analog) transmission optimization. Firstly, a dynamic streaming method based on user viewpoint and pyramid projection was used to implement a complete edge cloud VR system. Then, HDA transmission was introduced to optimize the transmission, and a heuristic algorithm for resource allocation was given. Finally, the base station protocol stack was transformed, and the MEC was integrated into the LTE (long term evolution) system to implement a complete mobile edge cloud VR system. Experimental results demonstrate that the proposed scheme has good robustness and efficient transmission by comparing with the existing schemes. © 2020, Editorial Board of Journal on Communications.
