Abstract: A method to encode high dynamic range and wide color gamut video content with a backward compatible base layer. The base layer may be an HDTV or UHDTV program with Rec.709 colorimetry coded with AVC/H.264 or HEVC/H.265. The coding method provides information for properly rendering the content on displays with a wide range of color and brightness capabilities.

Abstract: 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.
