Rockchip VR solution cheap analysis: Thousand yuan 2K screen VR helmet will blowout

The release of three revolutionary VR devices at the beginning of the Oculus Rift, HTC Vive, and Sony PlayStation VR made VR virtual reality no longer out of reach. However, these three virtual reality headsets are not independent computing devices and need to rely on the host to use. The Oculus Rift and HTC Vive are high profile PCs, and the Sony PlayStation VR is a PS4 game console. Even if the full set of the cheapest PS VR costs nearly 1,000 US dollars, it is not affordable for the average consumer.


In general, immersive VR devices can be classified into three categories: external head mounted devices, integrated head mounted devices, and glasses boxes. Since external headsets can't afford to buy, you can only consider two other types of VR devices. However, a few tens of dollars of cheap glasses cases, even with the high-end mobile phone experience is very bad, the best program is an integrated headset. This type of integrated VR helmet is also quite a selection, such as the latest release of Pico VR, Pico Neo Developer Edition uses Qualcomm Snapdragon 820 platform, priced from 1899 yuan.

Unfortunately, the cost of the Qualcomm Snapdragon 820 platform is high and there are still a lot of development costs. It is difficult to reduce the cost to less than 1,500 yuan. The Rockchip VR solution RK3399 solves this problem very well. As the main chip supplier of domestic flat and TV boxes, Rockchip's solution is not only low cost, but also provides a one-stop turnkey solution. The development cost of integrated VR is greatly reduced.


Rockchip RK3399 is fully optimized for VR virtual reality technology, which can not only quickly lower the overall threshold of VR products, but also ensure that the good experience brought by VR technology can be fully applied.

1, 4K 360 panoramic video decoding compatible with ordinary 2D and 3D film sources

With 360° VR cinema, 360° VR video applications, and 360° VR video clips, the 360° panoramic video supported by hardware devices will become the hardware standard for VR products. Rockchip Microchip's mainstream processors can support 360° panoramic video decoding up to 4K resolution, and are also compatible with common 2D and 3D chip sources, providing hardware solution capabilities for the application layer.

2. Low latency technology for VR depth optimization is less than 20ms

The VR experience actually requires a complicated technical process. From the sensor acquisition, transmission, game engine processing, driving hardware rendering screens, liquid crystal pixel color switching, and finally to the human eye to see the corresponding picture, each step in the middle will produce a delay. At present, globally accepted acceptable VR delay is less than 20ms, otherwise it will cause strong discomfort such as dizziness, vomiting. Most VR devices currently do not meet the standard.

3, display refresh frame rate higher than 75Hz

The screen refresh rate is an important parameter that directly affects the VR product experience. Rockchip Micro Rockchip supports screen refresh rates up to 75Hz. Far beyond the standard of 60Hz refresh rate for common consumer VR products. A solution with a sufficiently high frame rate will quickly eliminate the industry's threshold and facilitate the rapid entry of more brands and manufacturers.

4, support 2K / dual FHD high-resolution screen

For VR display hardware support, Rockchip Micro Rockchip already supports 2K/Dual FHD high resolution screens. This hardware specification is also a mainstream configuration of high-end products in current VR products, which facilitates the rapid mass production of its solution terminal products.

5, support optical software anti-distortion, inverse dispersion, pupil distance adjustment algorithm

Rockchip Micro Rockchip is highly targeted on VR software technology. For the problems of distortion, color difference, and edge blurring produced by VR products, anti-distortion, inverse dispersion, and interpupillary distance adjustment algorithms can be automatically implemented through software detection and correction. This has a great advantage for terminal production, making up for the shortcomings of traditional hardware manufacturers in the field of software technology, and reducing the investment and time spent by brand manufacturers on hardware and software, and R&D costs.

6, support software and hardware two split screen mode

Rockchip Micro Rockchip split-screen technology has been quite mature, can support two kinds of software and hardware split screen. Not only can the resolution be automatically adapted, but also active optimization ensures stability. In addition, based on the underlying image technology, textures, light and shadow, screen detail, and distortion control can all achieve the best visual experience. In the game, 3D movie experience, immersive feeling is strong.

7, support the mainstream platform of the game engine

As the core partner of the ARM system, Rockchip's mainstream flagship chip solutions have high-performance CPUs and GPUs. For example, the latest Mali-T860. Based on the higher-end image processor, Rockchip Micro Rockchip supports mainstream game engine technology in VR products, including Geomerics Enlighten's global real-time light engine in Unity and more. Provide more gorgeous visual effects for VR games, visual lighting, scenes, textures, and detailed lighting effects.

Editor Comments: Based on these excellent features and Rockchip's leading customer network, it can be predicted that RK3399 is likely to become the most mainstream chip solution for integrated VR helmets in China this year. In addition, RK3399 integrates dual USB3.0 Type-C interface, dual ISP pixel processing, support gesture recognition, built-in PCI-e interface and so on. These new technologies can bring more application extensions and playability to VR devices and enhance VR experience and comfort.
