First Claim
1. An apparatus of a multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MT SI) receiver operable to support region of interest (ROI) signaling with a MTSI sender, the apparatus including one or more processors and memory configured to:
- receive, at the MTSI receiver, a requested region of interest (ROI);
signal the requested ROI for transmission to the MTSI sender via a real-time transport control protocol (RTCP) feedback message; and
decode, at the MTSI receiver, encoded video received from the MTSI sender, wherein the encoded video corresponds to the requested ROI.

Abstract
Technology for 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 receive a requested region of interest (ROI). The MTSI receiver can signal the requested ROI for transmission to the MTSI sender via a real-time transport control protocol (RTCP) feedback message. The MTSI receiver can decode encoded video received from the MTSI sender. The encoded video can correspond to the requested ROI.

12. At least one non-transitory machine readable storage medium having instructions embodied thereon for supporting video region of interest (ROI) signaling between a first multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) client and a second MTSI client, the instructions when executed perform the following:
-
defining, using one or more processors of the first MTSI client, a region of interest (ROI) within a field of view of the second MTSI client; formatting, using the one or more processors of the first MTSI client, the ROI for transmission to the second MTSI client via a real-time transport control protocol (RTCP) feedback message that directs the second MTSI client to capture video that corresponds to the ROI and encode the video that corresponds to the ROI; decoding, using the one or more processors of the first MTSI client, encoded video that corresponds to the ROI received from the second MTSI client, the encoded video including regions that correspond to the ROI and excluding regions that do not correspond to the ROI, the encoded video including the regions that correspond to the ROI at an increased zoom level while substantially maintaining a defined quality level; decoding, using the one or more processors of the first MTSI client, an actual ROI received from the second MTSI client that corresponds to the encoded video from the second MTSI client, wherein the actual ROI is received via a real-time transport protocol (RTP) header extension; and providing, using the one or more processors of the first MTSI client, the encoded video that corresponds to the ROI for rendering and display at the first MTSI client. - View Dependent Claims (13, 14, 15, 16)

17. An apparatus of a multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) sender operable to support video region of interest (ROI) signaling with a MTSI receiver, the apparatus including one or more processors and memory configured to:
-
decode, at the MTSI sender, a region of interest (ROI) received from the MTSI receiver, wherein the ROI is received via a real-time transport control protocol (RTCP) feedback message generate, at the MTSI sender, encoded video that corresponds to the ROI, the encoded video including regions that correspond to the ROI and excluding regions that do not correspond to the ROI, the encoded video including the regions that correspond to the ROI at an increased zoom level while substantially maintaining a defined quality level; and signal the encoded video to a transceiver of the apparatus for transmission to the MTSI receiver to enable the MTSI receiver to render and display the encoded video that corresponds to the ROI. - View Dependent Claims (18, 19, 20, 21)
