By moving a large number of local computing to the cloud, cloud VR, on the one hand, saves expensive and bulky local computers and removes the connecting lines, so as to realize convenient movement, light weight and low cost; On the other hand, VR content aggregation is realized to protect copyright.

At present, the main bottleneck in the development of VR industry lies in the imbalance between cost and user experience. Cloud VR solution will solve this pain point and is the inevitable choice for VR to move towards large-scale application.

The improvement of cloud VR performance also puts forward higher requirements for network bandwidth and delay. At present, 4G network is still difficult to meet. The transmission rate of 5g network can reach 10Gbps, 100 times that of 4G; The transmission delay can reach 1ms, which is 1 / 50 of 4G. It is expected to help the real implementation of cloud VR and expand more application fields.

All in one machine will become the mainstream form of VR / AR equipment in the future

After the bubble burst, the development trend of VR device configuration has been gradually determined, and industry related standards have also been launched. High-performance, all-in-one (cordless) VR equipment that will provide complete immersion will be the mainstream of the future.

According to IDC’s report, from 2017 to 2019, the global shipments of VR devices without screen viewer decreased year by year, and the proportion of shipments in 2019 is expected to decrease from 60% in 2017 to 16%; The shipment volume of standalone HMD is increasing year by year. It is estimated that it will reach 2.69 million units in 2019, and the proportion of shipment volume will increase from 4% in 2017 to 38%; The proportion of PC VR equipment (tethered HMD) shipments increases slightly every year, and is expected to be 46% in 2019.

The VR industry is facing a bottleneck, and the cloud VR solution will solve this pain point

At present, users generally reflect that when using PC VR devices to experience VR games, their hands will hook the cable connecting the headset device to the host from time to time, which greatly affects the game experience. For AR devices, cable binding is an obstacle to the further expansion of application scenarios. Therefore, cordless must be the future trend of VR / AR equipment, and all-in-one machine will become the mainstream form of VR / AR equipment in the future.

Cloud VR helps the scale of VR industry

Although the all-in-one VR device has the advantages of mobile portability, it also sacrifices the computing performance, so the current user experience is difficult to compare with the PC VR device. In order to solve this problem, the industry puts forward the solution of cloud VR, moves a large number of local computing to the cloud, introduces cloud computing and cloud rendering technology, and transmits the cloud display output and sound output to the user’s terminal equipment after coding and compression with the help of high-speed and stable network, so as to eliminate the need for local host.

On the one hand, the scheme eliminates the connecting line between VR head display and host, and realizes convenient movement; On the other hand, it saves expensive and bulky high-performance local computers and realizes light weight and low cost.

At present, the main bottleneck in the development of VR industry lies in the imbalance between cost and user experience. Therefore, cloud VR solution is the inevitable choice for VR to move towards large-scale application. Cloud VR not only solves the pain point of hardware, but also solves the pain point of content production and distribution. Previously, VR content was discrete and without copyright protection. Cloud VR enables VR content to be aggregated. On the one hand, it has copyright protection, on the other hand, it can realize rapid distribution to the public and vertical industry users.

Cloud VR solution architecture consists of content layer, platform layer, network layer and terminal layer. Content layer: mainly responsible for providing VR content to the platform layer, including content providers and content aggregators; Platform layer: provide cloud rendering, streaming, transcoding, storage and coding functions for VR content; Network layer: it mainly includes backbone network, metropolitan area network, access network and home network, which is responsible for providing stable transmission of cloud VR services with large bandwidth and low delay; Terminal layer: it mainly realizes the functions of VR content presentation, home network access and user authentication. It is connected to the network through Wi Fi / 5G and connected to the platform layer.

5g network performance has been greatly improved to help cloud VR landing

The clarity and fluency of VR experience can be improved by improving the resolution and refresh rate of VR content / terminal respectively. While improving the above performance, it also puts forward higher requirements for network bandwidth and delay. Weak interactive VR mainly puts forward higher requirements for network bandwidth; Strong interactive VR puts forward higher requirements for network bandwidth and delay.

The current transmission schemes of weak interactive VR include full view transmission and FOV transmission. The former requires more bandwidth, and strong interactive VR has only FOV transmission. The full view transmission scheme is to transmit the pictures surrounded by 360 degrees to the terminal. When the user’s head rotates and needs to switch the pictures, all processing is completed locally at the terminal. The full view transmission scheme is adopted. When viewing, the viewer can only see the current view, and the invisible part accounts for the network bandwidth, but it is not really used, resulting in a great waste of network resources. Therefore, the industry has proposed the FOV (field of view) transmission scheme, which only transmits the high-quality view area and does not involve the non view area.

At present, FOV transmission schemes include pyramid transmission and tile wise transmission. According to Huawei’s white paper on cloud VR network solutions 2018, in the comfort experience phase of VR, the full view transmission bandwidth of weak interactive VR video applications is required to reach 140mbps, the FOV transmission bandwidth is required to reach 75mbps, and the transmission bandwidth of strong interactive VR applications is required to reach 260mbps.

In order to achieve VR applications in the comfort experience stage, the current 4G network is difficult to meet the above performance requirements. In 2020, 5g commercial will significantly improve network performance, which is specifically reflected in transmission rate, delay, connection density and mobile speed.

The transmission rate of 5g network can reach 10Gbps, 100 times that of 4G; The transmission delay can reach 1ms, which is 1 / 50 of 4G; The connection density can reach 106 / km2, 100 times that of 4G; The mobile speed can reach 500km / h, which is 1.5 times that of 4G.

According to the 5g cloud virtual reality white paper jointly released by Shanghai Bell and ICT Institute, 5gr15 will start to increase the downlink bandwidth to 100mbps-1gbps, reduce the network delay to 10ms, and start to enter the next stage of VR experience. At that time, the clarity and fluency of VR equipment will be further improved, motion sickness will be eliminated, the product weight will be reduced, the cost will be reduced, and the industry is expected to start to enter large-scale application.
