Interactive video conferencing
First Claim
1. An apparatus of a multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) receiver operable to support region of interest (ROI) signaling with a MTSI sender, the apparatus comprising one or more processors and memory configured to:
- define, at the MTSI receiver, a requested region of interest (ROI)map, at the MTSI receiver, the requested ROI to one or more pan, tilt, zoom and focus (PTZF) commands;
store, in the memory, the one or more PTZF commands that are mapped to the requested ROI;
signal the one or more PTZF commands representing the requested ROI for transmission to the MTSI sender via real-time transport protocol (RTP) packets, wherein the requested ROI is identified at the MTSI sender based on the one or more PTZF commands; and
decode, at the MTSI receiver, encoded video received from the MTSI sender, wherein the encoded video is within the requested ROI.

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.

8. At least one non-transitory machine readable storage medium having instructions embodied thereon for operating a video conferencing application at a local client that supports an interactive zooming feature, the instructions when executed by one or more processors cause the local client to perform the following:
-
defining a region of interest (ROI) within a field of view of a camera associated with a remote client; mapping the ROI to one or more pan, tilt, zoom and focus (PTZF) commands; processing the one or more PTZF commands for transmission from the local UE client to the remote client via real-time transport protocol (RTP) packets, wherein the ROI is identified at the remote client based on the one or more PTZF commands; decoding encoded video within the ROI received from the remote client, the encoded video including regions within the ROI and excluding regions outside the ROI; and providing the encoded video within the ROI for rendering and display at the local client. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An apparatus of a remote user equipment (UE) operable to perform video conferencing with a local UE, the apparatus comprising one or more processors configured to:
-
process, at the remote UE, one or more pan, tilt, zoom and focus (PTZF) commands received from the local UE via real-time transport protocol (RTP) packets; identify, at the remote UE, a region of interest (ROI) based on the one or more PTZF commands, the ROI being within a field of view of a camera of the remote UE; encode video within the ROI, the encoded video including regions within the ROI and excluding regions outside the ROI; and process, at the remote UE, the encoded video within the ROI for transmission to the local UE. - View Dependent Claims (16, 17, 18, 19, 20)
