Interactive zooming in video conferencing

摘要

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.

1. A method performed by a local user equipment (local UE) for zooming within a video conferencing application that provides two-way video communication between the local UE and a remote user equipment (remote UE), the method comprising:
defining, at the local UE, a user-defined region of interest (ROI) within a field of view at the remote UE, without changing the field of view of the remote UE; directing the remote UE to capture video within the ROI, without changing the field of view of the remote UE; receiving, at the local UE, the captured video from the remote UE, the received video including regions within the ROI and excluding regions outside the ROI; and displaying, at the local UE, the received video.
