Abstract: 5G is expected to bring prosperity of video applications, including significantly improving existing applications and bringing forth new exciting applications. To meet the challenges of 5G video applications, such as ultra low latency, high reliability and high quality of experience, ZTE proposes the concept of constructing smart real time video network (SmartRTN). Based on this concept, ZTE innovatively develops a series of technologies and solutions, including low bitrate high quality video compression based on content intelligent analysis, ultra low latency video transportation, smart video processing and enhancement based on deep learning, networking solutions and intelligent scheduling strategies combining edge computing and network slicing. These technologies and solutions have been applied in all end-to-end video service processes, effectively solving the technical bottlenecks that beset 5G video service development.
