MTSI based UE configurable for video region-of-interest (ROI) signaling
First Claim
1. An apparatus of a multimedia telephony services over an IP multimedia subsystem (MTSI) based user equipment (UE) configurable for video Region-of-Interest (ROI) signaling and operation as an MTSI sender, the apparatus comprising:
- memory; and
processing circuitry configured to;
perform a Session Description Protocol (SDP) capability negotiation with a MTSI receiver;
provide a set of predefined ROIs to the MTSI receiver during the SDP capability negotiation;
receive signaling for one of the predefined ROIs in RTCP feedback reports from the MTSI receiver when the MTSI receiver is operating in a predefined ROI mode; and
encode a region corresponding to the one of the predefined ROIs of a captured frame, the encoded video comprises the encoded region of the captured frame and refrain from encoding video outside the predefined ROI of the captured frame.

Abstract
In a video conferencing application, a user viewing a scene can performing zooming by selecting an area in the scene, then dynamically switching a video feed of the scene to the selected area of the scene. The hardware and software of the video conferencing application can limit the video transmitted to the user to include only the selected area of the scene. Transmitting only the selected area of the scene, and excluding the non-selected area of the scene from transmission, can more efficiently use the available bandwidth of the video conferencing application.
