Abstract:
A system and method for providing quality control in 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 paused video frame is equalized such that it is of same value for all the video tiles, which may be the video quality of the tiles presented in a viewport of the client device. The paused video frame having the same quality tiles throughout is used as a replacement 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.
