Abstract
A system and method for providing quality control in 360° immersive video during pausing of a video streaming session, wherein a paused video frame may comprise a plurality of mixed quality video tiles depending on user gaze vector information. Under pause control of a video optimization node, 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. In one embodiment, a custom replacement video frame is generated having tiles with the same equalized video quality throughout the full 360° immersive video frame, e.g., an X-frame, is presented to the client device player for decoding and displaying instead of the mixed quality video frame while the streaming session is paused. In another embodiment, a still image based on the custom replacement video frame is provided to the client device to display instead of the mixed quality paused video frame.
