Recently, Tencent Multimedia Lab has released a new "VR Technology White Paper", focusing on a set of industry-leading VR video transmission solutions. This innovative solution will not only bring users a higher definition and more immersive viewing experience, but also further promote the popularization and application of VR technology, and bring more innovation and possibilities to the digital industry in the future.

Traditional VR video has been subject to network transmission and hardware equipment conditions, Tencent Multimedia Lab proposed and adopted a new end-to-end transmission strategy, successfully broke through the transmission bottleneck. The laboratory adopts FOV transmission scheme, which skillfully reduces the bandwidth requirement in full-view transmission, and allows users to enjoy lower-cost and high-quality pictures when watching VR videos. By dividing the 360 °picture into multiple pieces and transmitting only the video in the current field of view, the problem of wasting bandwidth of the picture outside the field of view is successfully avoided.

At present, the scheme has greatly improved in terms of bandwidth savings, FOV handover delay optimization and fluency upgrade, ensuring the smooth playback of VR videos in different scenes and providing users with a more excellent viewing experience. At the same time, the technical solution has also been successfully applied in many fields, such as culture, travel, exhibition and so on. Whether it is slow live streaming, online meetings or other application scenarios, this innovative solution brings users a more real and clear virtual reality experience.

Prior to this, Tencent Multimedia Lab and Tencent Research Institute released "all-True Internet: 3D presence". The report pointed out that all-True Internet is an important trend of the next generation Internet. The promotion of the dimension of the technology carrier promotes the development of plane video to interactive video, from the two-dimensional application of words and pictures to the new application of digital human + digital space composed of spatial elements. from plane interaction to three-dimensional interaction of multi-mode and spatial computing.

Dr. Liu Shan, head of Tencent Multimedia Lab, pointed out: "True interconnection needs to build a high-dimensional and diverse digital media world corresponding to the real world, and provide users with an immersive and interactive real experience. Tencent Multimedia Lab has been committed to the investment and construction of immersive media technology, extending the team's profound technology accumulation in the traditional multimedia field to 3D media technology, including panoramic video, 3D reconstruction, free perspective, virtual and real fusion, digital twin, 6-degree-of-freedom holographic video, etc., and built a full set of immersive media system links from front-end acquisition to terminal rendering interaction. The cutting-edge technology research and landing application development of these immersive media technologies have provided the underlying driving force for the Quanzhen Internet, many of which have served various businesses of Tencent.

VR takes us to watch the snow in the Imperial Palace and listen to Yunnan songs at home; the 3D reconstruction technology of point cloud takes you through immersive browsing of the employees of the Goose Factory in Tencent's start-up office district to return to the entrepreneurial road; 6DoF media system captures and preserves all the details of Chinese precious cultural relics and diverse traditional culture. Through the effective support of a series of applications, with the continuous iterative progress of immersive media technology, the all-real Internet with the integration of data and reality will be closer and closer to us.
