VR Black Technology Sharing: Field of View Adaptive Live Streaming (FOVAS) Technology Saves VR Video

VR video has long been used in movies. Such as the "speed and passion 7", "Avenger Alliance 2" and other well-known game experience [1] 2016 is called the VR first year, the industry should have no objection. In addition to the upstream of the industry, the action is frequent, the level of the general consumer market is quite harmonious, and the sales volume of all kinds of true and false low-end VR glasses that are constantly refreshed by a certain treasure is one of the powerful evidences.

The works all try to use virtual reality technology. Currently, in the VR field, the most lacking is content, and for the video industry, content is always generated. If the video content and VR technology can be well combined, it will add visibility to the film industry; but the viewing experience of VR video is really unrecognizable.

When the old drivers are eager to put the VR resources downloaded online into the mobile phone, copying the VR glasses directly into the panoramic video world, the result will generally be disappointing: the immersion is enough, but the slag picture is really too spicy. . .

Although this pot of VR glasses has to be backed, the quality of panoramic video also greatly affects the user experience. More and more 360 ​​cameras now support 4K video capture, but due to network bandwidth issues, most users are now unable to enjoy the high-definition virtual reality experience.

However, Pixvana, a VR video company that has been focusing on cloud technology for many years, today released the SPIN 360 video platform with field-of-view adaptive live broadcast (FOVAS) technology, which can bring you a more high-definition VR world with the smallest bandwidth, and the highest can reach amazing. 10K effect!

It is understood that Pixvana developed FOVAS technology to solve the problem of resolution of VR video. Pixvana, who is proficient in cloud technology, found that when people are immersed in the 360-degree world, in fact, we are still only the images in front of us. No matter how wonderful the picture behind us, there is no way to watch them at the same time. So they did this for the video:

Divide the video into different fields of view and separate the video that the user sees from different angles;

When the user turns around, the video will switch to the corresponding angle of the picture, and the picture that is still watching will not occupy the bandwidth.

Field of view adaptive live broadcast (FOVAS) technology

After these steps, the amount of data actually transmitted by the video will be greatly reduced without affecting the viewing experience of the user. Pixvana researchers say that using FOVAS technology to play 10K video can reduce the amount of data transmission by 70%, so VR players will get the best video quality with the same bandwidth.

For your convenience, Pixvana also offers the Open ProjecTIon Format format, which helps video publishers divide their content into multi-view formats (a total of 30), allowing VR users to instantly get rid of AV quality and embrace the HD world!

However, FOVAS technology is currently only available for online playback. Compatible applications will be logged into Steam in the near future. If the player is officially launched, it is estimated that it will wait until 2017. The VR video used to be enveloped by the "mysterious fuzzy power", and the arrival of FOVAS technology seems to let everyone completely get rid of the "mosaic"!
