Abstract
Technology for a local user equipment (UE) operable to perform video conferencing with a remote UE is disclosed. The local UE can define a region of interest (ROI) within a field of view of a camera of the remote UE. The local UE can map the ROI to one or more pan, tilt, zoom and focus (PTZF) commands. The local UE can send the one or more PTZF commands to the remote UE, wherein the remote UE is configured to identify the ROI based on the one or more PTZF commands. The local UE can receive encoded video within the ROI from the remote UE. The encoded video can include the regions within the ROI at an increased zoom level while substantially maintaining a defined quality level to enable the encoded video within the ROI to be rendered and displayed at the local UE.
