GTI Ad-hoc——5G Cloud XR (with video)
Report in Collaboration with the GSMA Highlights Best Practice from National 5G Plans
GTI Technology Ad-hoc series events were successfully held on 11th-12th November, 2020 in Shanghai, China. With greater focus on the two main themes of 5G ENS5G Cloud XR, the events intend to explorediscuss key issues such as standards, technologiesbusiness applications that are faced by the industry,to showcase innovative solutionsthe latest achievements.
The 5G Cloud XR event was attended by more than 20 partners from the fields of content production, network, device, rendering engine, graphicsimage, etc. It has provided a critical platform to have an in-depth discussion on the technical requirementssolutions for Cloud XR renderingperceptual computing,on the challengessuggestions for standardization, technological breakthroughindustry development.
1. Content Production
lBy observing the changes of macro environmentconsumer market, we can find that the overall industry is developing rapidly, but high-quality XR content supply remains the main obstacle to the development of the industry. Currently, 4k8k VR content is still in its infancy, while high resolutionhigh bitrate also depend on high performance communication network.
lThe most important significance of 5G to the video industry is not only the increase in transmission rate, but also the increase in information. 5G will reconstruct the way of content productiondissemination. Its low-latency, high-bandwidth,wide-coverage features can push video contentreal-world scenes,break the limitations of viewing anglesspace, which provide users a more personalizedsocial experience.
lXR immersive experience includes HDR, accuratenatural gesture interactionetc. At present, the ecology of XR is in full bloom in terms of ID design, optics, platform architecturehybrid computing. To achieve generalaffordable immersive experience, interface standardization, cloudification, 5Gedge computing are the direction to go.
l5G network “cloud-edge-terminal” architectureits technological dividends have become an important boost for the rapid development of immersive business,5G Cloud XR has been widely observed as a promising business model.
lInto address challenges of bandwidth, latency,liability during the implementation of the 5G Cloud XR application, cooperation in standard technology needs to be strengthened further. We need to accelerate platform constructionnetwork performance of 5G Cloud XR based on the analysis of XR transmissionthe evaluation of XR user experience.
lThrough high-definition rendering pipeline HDRP, high-performance game operating architecturestreaming rendering technology, it is possible to realize the seamless high-definition world in "Ready Player One".
lWith the rapid development of cloud XRcloud gaming, real-time rendering technology is transitioning from pure client/terminal rendering to real-time cloud rendering.
lOpenXR defines a common API that all XR runtimes can expose to applicationengine developers, enabling XR software to be written only one time and can run on any OpenXR compatible hardware. OpenXR enables device vendors to innovate in the designimplementation of their hardwareruntimes.
lDuring the commercialization of Cloud XR services, the lack of standards was serious, which caused great obstacles to the development of the industry. For example, the adaptation interfaces between different terminalsthe cloud, the development interface between cloud capabilitiesengines,the control interface between peripheral devicesservices are all lack uniform standards.
lIn the near future, GTI will collaborate with Khronos Group to carry out standard formulation of Cloud XR interface in OpenXR API. In 2021, standardization in device API of cloud XR will be the top priority, to place a foundation for the unified processecosystem.
GTI established the 5G Cloud XR working groupannounced the working plan at the event. It will join hands with various vendors of industry chains to carry out key technology research, standard formulation, application landing, to accelerate the industry developmentcommercial use of 5G Cloud XR.
