[Abstract] In this paper, two kinds of technical development challenges faced by virtual reality (VR) are proposed: high bandwidth and low delay. Focusing on the development of VR, ZTE innovatively proposed the technical concept of an end-to-end VR system solution. A series of innovative technologies were developed to implement VR services, such as low-code high-definition technology and angle of view (FOV)-based adaptation transmission technology, VR electronic program guide (EPG), VR set-top box, VR player, and cloud-based VR network architecture based on network function virtualization (NFV) technology. These technologies and solutions further promote the development of VR.
