SYSTEM AND METHOD FOR DEPTH BASED ADAPTIVE STREAMING OF VIDEO INFORMATION

摘要

Systems and methods for adaptive bitrate streaming of video information are provided. If a depth map can be derived or is independently available for the image sequence, the depth map can be used to selectively blur (effectively reducing the resolution of) background areas and to select encoding quantization parameters by image region in order to throttle the bitrate. In a cloud-based gaming application, the depth information can be used to selectively render background layers at lower resolutions thereby improving the compression efficiency of the rendered images.
