Dynamic adaption of a continuous presence videoconferencing layout based on video content
First Claim
1. An apparatus for controlling building a continuous presence video image in a video conference, comprising:
- a control module, configured to perform actions comprising actions that cause the control module to;
receive parameters of a region of interest from a first endpoint of a plurality of endpoints;
design a continuous presence layout based on the parameters of the region of interest; and
an editor module, associated with a second endpoint of the plurality of endpoints, configured to perform actions comprising actions that cause the editor module to;
receive instructions on how to manipulate and place a video image generated by the first endpoint in a continuous presence video image according to the continuous presence layout for display by the second endpoint.

Abstract
Dynamically adapting a continuous presence (CP) layout in a videoconference enhances a videoconferencing experience by providing optimum visibility to regions of interest within the CP layout and ignoring regions of no interest. Based on the CP layout, a CP video image can be built, in which a conferee at a receiving endpoint can observe, simultaneously, several other participants'"'"' sites in the conference. For example, more screen space within the CP layout is devoted to presenting the participants in the conference and little or no screen space is used to present an empty seat, an empty room, or an unused portion of a room. Aspect ratios of segments of the CP layout (e.g., landscape vs. portrait) can be adjusted to optimally present the regions of interest. The CP layout can be adjusted as regions of interest change depending on the dynamics of the video conference.
