Abstract: A method of ultra-low rate video encoding, including capturing a frame within a video stream, capturing a global position of the frame, capturing a heading of the frame, linking the global position and the heading to the frame, determining a foreground of the frame based on the global position of the frame and the heading of the frame, determining an at least one region of interest within the foreground, analyzing the at least one region of interest, removing a background from the frame based on the global position and the heading, wherein the background is complementary to the foreground and encoding the foreground, the global position, the heading and the at least one region of interest.

Abstract: A residual up-sampling apparatus has a residual up-sampling buffer and a shared residual up-sampling circuit. The residual up-sampling buffer stores an intermediate residual up-sampling result. The shared residual up-sampling circuit employs a same processing kernel to perform a first-direction residual up-sampling operation and a second-direction residual up-sampling operation. The first-direction residual up-sampling operation processes an inverse transform output of an inverse transform circuit to generate the intermediate residual up-sampling result to the residual up-sampling buffer. The second-direction residual up-sampling operation performs transpose access upon the residual up-sampling buffer to retrieve the intermediate residual up-sampling result, and processes the intermediate residual up-sampling result to generate a final residual up-sampling result.

Abstract: Technology for a local user equipment (UE) operable to perform video conferencing with a remote UE is disclosed. The local UE can receive a set of predefined region of interests (ROIs) from the remote UE. The local UE can select a predefined ROI from the set of predefined ROIs received from the remote UE. The local UE can communicate the predefined ROI to the remote UE that directs the remote UE to capture video within the predefined ROI and encode the video within the predefined ROI. The local UE can receive encoded video within the predefined ROI from the remote UE. The encoded video can include regions within the predefined ROI and excluding regions outside the predefined ROI. The local UE can provide the encoded video within the predefined ROI for rendering and display at the local UE.
