VR services have very high demand for bandwidth and computing resources, which are challenges for the independent HMD terminals. The current mainstream of VR over Internet lies in two aspects, 360 degree panorama video and VR games. They have different practical solutions for streaming. For panorama video transmission, tile-based viewpoint-dependent framework comes out as an practical solution, which significantly reduces the high requirement in bandwidth, while exposed to the problem of limited decoding resources. An overall optimization is needed, involving system framework, code stream fusion, fast switching, quality measurement and other technologies. VR games resort to the cloud based interactive VR system, which reduces the demand for high computing resources, while facing the challenge of low delay. A joint design of the transmission mechanism, distortion measure, playback strategy, display strategy and etc. is the key to its solution.
