Abstract

The invention discloses a cloud rendering dynamic coding method, and particularly relates to the field of VR, and the method comprises the following operation steps: S1, obtaining the FOV and Rotationof a Sensor: obtaining the FOV and Rotation in an HMD drive layer; S2, adjusting the FOV according to the change of the Rotation; S3, sending the FOV data and the Rotation data to a Server: sending the adjusted FOV data and the Rotation data to the Server through a UDP; and S4, rendering the image according to the FOV data and the Rotation data: after receiving the data, enabling the Server to send the FOV data and the Rotation data to an application program, and enabling the CUDA to adjust the Camera according to the current FOV data and the Rotation data for rendering. By adopting the technology, the black edge of a picture can be reduced when a terminal user turns a head, the refreshing efficiency is higher, the dizziness feeling is reduced, and the VR content can be better experienced. In order to solve the problem that in VR cloud rendering game experience, a user needs to adjust the picture display resolution and the code rate to improve the coding efficiency in the motion stateand the forbidden state, and therefore a better display effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of VR, and more specifically, the present invention relates to a cloud rendering dynamic encoding method. Background technique [0002] Dynamic encoding includes CBR encoding and VBR encoding. [0003] The use of CBR encoding in the streaming playback scheme is the most effective. When using CBR encoding, the bit rate is basically kept constant and close to the target bit rate during the streaming process, and is always within the time window determined by the buffer size. The disadvantages of CBR encoding The quality of the encoded content is unstable, because some segments of the content are more difficult to compress than others, so some parts of the CBR stream are of worse quality than others. In addition, CBR encoding will cause the quality of adjacent streams to be different, usually At lower bitrates, the change in quality will be more noticeable; use VBR when planning to make content availab...
