INTERACTIVE VIDEO CONFERENCING
First Claim
1. A local user equipment (UE) operable to perform video conferencing with a remote UE, the local UE having one or more processors configured to:
- define a region of interest (ROI) within a field of view at the remote UE;
communicate the ROI to the remote UE via a real-time transport control protocol (RTCP) feedback message that directs the remote UE to capture video within the ROI and encode the video within the ROI;
receive the encoded video within the ROI from the remote UE, the encoded video including regions within the ROI and excluding regions outside the ROI, the encoded video including the regions within the ROI at an increased zoom level while substantially maintaining a defined quality level;
receive actual transmitted ROI corresponding to the encoded video from the remote UE via a real-time transport protocol (RTP) header extension, the RTP header extension being included in RTP packets that contain the encoded video; and
provide the encoded video within the ROI for rendering and display at the local UE.

Abstract
Technology for operating a video conferencing application at a local user equipment (UE) that supports an interactive zooming feature is disclosed. A local UE can define a region of interest (ROI) within a field of view at a remote UE. The local UE can communicate the ROI to the remote UE via a real-time transport control protocol (RTCP) feedback message, wherein the RTCP feedback message directs the remote UE to capture video within the ROI and encode the video within the ROI. The local UE can receive the encoded video within the ROI from the remote UE, the encoded video including regions within the ROI and excluding regions outside the ROI. The local UE can receive actual transmitted ROI corresponding to the encoded video from the remote UE via an RTP header extension. The encoded video within the ROI can be rendered for display at the local UE.

19. A method for operating a video conferencing application at a local user equipment (UE) that supports an interactive zooming feature, the method comprising:
-
defining, at the local UE, a region of interest (ROI) within a field of view at a remote UE, using one or more processors of the local UE; communicating the ROI to the remote UE via a real-time transport control protocol (RTCP) feedback message, wherein the RTCP feedback message directs the remote UE to capture video within the ROI and encode the video within the ROI, using the one or more processors of the local UE; receiving the encoded video within the ROI from the remote UE, the encoded video including regions within the ROI and excluding regions outside the ROI, the encoded video including the regions within the ROI at an increased zoom level while substantially maintaining a defined quality level, using the one or more processors of the local UE; receiving actual transmitted ROI corresponding to the encoded video from the remote UE via a real-time transport protocol (RTP) header extension carried in RTP packets containing the encoded video, using the one or more processors of the local UE; and rendering the encoded video within the ROI for display at the local UE via the video conferencing application, using the one or more processors of the local UE. - View Dependent Claims (20, 21, 22, 23, 24, 25)
