Abstract: A cloud gaming system includes a cloud gaming server that provides rendering for a video frame employed in cloud gaming. The cloud gaming system also includes a video frame latency reduction pipeline coupled to the cloud gaming server, having a slice generator that provides a set of separately-rendered video frame slices required for a video frame, a slice encoder that encodes each of the set of separately-rendered video frame slices into corresponding separately-encoded video frame slices of the video frame and a slice packetizer that packages each separately-encoded video frame slice into slice transmission packets. The cloud gaming system further includes a cloud network that transmits the slice transmission packets and a cloud gaming client that processes the slice transmission packets to construct the video frame. A video frame latency reduction method is also provided.
