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;
encode the one or more PTZF commands for transmission to the MTSI sender via real-time transport protocol (RTP) packets, wherein the one or more PTZF commands represent the requested ROI;
decode, at the MTSI receiver, encoded video received from the MTSI sender, wherein the encoded video is within the requested ROI; and
store, in the memory, the one or more PTZF commands that are mapped to the requested ROI.

Abstract
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 is disclosed. The MTSI receiver can define a requested region of interest (ROI). The MTSI receiver can map the requested ROI to one or more pan, tilt, zoom and focus (PTZF) commands. The MTSI receiver can encode the one or more PTZF commands for transmission to the MTSI sender via real-time transport protocol (RTP) packets. The one or more PTZF commands can represent the requested ROI.

8. At least one non-transitory machine readable storage medium having instructions embodied thereon for supporting an interactive zooming feature at a local client, 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 to the remote client via real-time transport protocol (RTP) packets; and 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 storing, in the memory, the one or more PTZF commands that are mapped to the requested ROI. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. At least one non-transitory machine readable storage medium having instructions embodied thereon for performing video conferencing between a remote user equipment (UE) and a local UE, the instructions when executed by one or more processors cause the remote UE to perform the following:
-
processing, 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; identifying, 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; encoding video within the ROI, the encoded video including regions within the ROI and excluding regions outside the ROI; and processing, at the remote UE, the encoded video within the ROI for transmission to the local UE. - View Dependent Claims (17, 18, 19, 20, 21)
