    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.

    Abstract: An apparatus for processing image or video information is provided. The apparatus comprises a memory circuit configured to store video content and enhancement information for the video content. The apparatus also comprises a processor coupled to the memory circuit. The processor is configured to generate a video frame of a frame size that is compliant with a frame format for video content having a first spatial resolution. The video frame comprises at least a first sub-frame and a second sub-frame. The first sub-frame comprises an image of video content having a second spatial resolution, the first spatial resolution being greater than the second spatial resolution. The second sub-frame comprises enhancement information for the video content of the first sub-frame.

    Abstract: An apparatus and method are provided to allow users of a device for video conferencing operating in a very low bandwidth environment to touch or gesture to an object or region of the image that they would like to see with improved quality. The feedback is then sent to the transmitting end where the selected region is encoded with higher quality parameters while other regions are pre-processed and encoded with fewer bits. Depth information, available through a depth camera or other method, may be used to determine the boundary of the selected object as well as to perform depth-based saliency detection and pre-processing of the image in order to reduce the overall required bandwidth.
