Summary

Recommendation ITU-T H.431.1, together with its related Recommendation ITU-T F.746.14, specifies the functional architecture of cloud virtual reality systems. It describes the overall functional architecture including control layer, resource layer, network layer, terminal layer, operation, administration and management, and security. This Recommendation also describes the basic functions of each layer, such as unified scheduling/technology integration/content distribution of the control layer, cloud-based operation on the resource layer and high-quality transmission by the network layer. The cloud virtual reality (VR) content can be run concurrently based on the cloud and is distributed to the terminal for presentation.
