Abstract:
A system and method for providing quality control in 360° immersive video during pausing of a video streaming session. In one embodiment, a paused video frame may comprise a plurality of mixed quality video tiles depending on user gaze vector information. Under pause control, the video quality of all tiles of the tiled video frame is equalized to a highest video quality corresponding to the quality of the tiles presented in a viewport. A replacement video frame is generated having tiles with the same equalized video quality throughout the full 360° immersive video frame, which is presented to the client device player for decoding and displaying instead of the mixed quality video frame while the streaming session is paused.
