Abstract

The invention provides a video data processing method and device, a video data transmission method and device and a video data processing system. Specifically, the video data processing method comprises the following steps: playing an omnidirectional video track switched from a first viewpoint to a second viewpoint; and according to the viewpoint information of the second viewpoint and / or the viewing direction of the user before switching from the first viewpoint, determining the initial viewing direction of the user when the omnidirectional video track is played. Through the methods and the devices, the problem that a user feels uncomfortable due to sudden change of window contents before and after viewpoint switching is solved, and the effect of improving the viewing experience of the user is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a video data processing, transmission method and device, and a video data processing system. Background technique [0002] VR (Virtual Reality) refers to the use of computer technology to simulate a three-dimensional virtual world, allowing users to experience a highly realistic virtual space environment in terms of vision, hearing, and touch. With the rapid development of VR technology, applications such as on-demand and live broadcast of VR video (also called omni-directional video) are becoming more and more widespread, bringing immersive video service experience to users. [0003] For the same scene, multiple omnidirectional videos can usually be taken at different physical locations (viewpoints), which is called multi-viewpoint omnidirectional video. Multi-view omni-directional video allows users to switch between multiple omni-directional videos based on the location inf...
