WIPO Patent Application WO/2023/219278
Kind Code:
A1
Abstract:
Disclosed is a method for grouping and updating camera parameters for an MPEG immersive video. In the present embodiment, an immersive video decoding device decodes the number of camera viewpoints, the number of scenes, the number of time steps, and the number of sensors. The immersive video decoding device decodes explicit camera parameters and implicit camera parameters for each of the scenes, each of the time steps, and each of the sensors on the basis of the number of camera viewpoints. Afterwards, the immersive video decoding device may extract viewports for a user by using the camera parameters suitable for each of the scenes, each of the time steps, or each of the sensors.
