A New Architecture of 8K VR FOV Video End-to-End Technology

With the rapid development of virtual reality (VR) technology and the increasing demand for higher video quality, streaming videos imposes stringent requirements on the network. To solve these problems, the Field of View (FOV) streaming is one the popular solutions. In streaming aspect, it's common to provide video service over Internet Protocol Television (IPTV) platform. The application of 8K VR FOV in IPTV platform can reuse the existing Content Delivery Network (CDN) architecture and set-top boxes (STBs), thus significantly reducing the complexity of the system. Furthermore, it can also accelerate the popularization of VR technology, and improve the service development of IPTV platform. Currently, most of the VR FOV solutions in industry are based on Dynamic Adaptive Streaming over HTTP (DASH), which are difficult to apply in most IPTV platforms. Our Real Time Streaming Protocol (RTSP) 8K VR FOV video end-to-end solution for IPTV platforms significantly reduces bandwidth by about 60% compared to the traditional solution, and provides the same subjective quality. We evaluate and compare the performance of our solution with traditional 8K solution. The results show the superiority of the proposed architecture in terms of bandwidth, latency and CPU utilization.
