Dynamic Adaption of a Continuous Presence Videoconferencing Layout Based on Video Content
First Claim
1. An apparatus for building, in a video conference, a continuous presence (CP) video image, comprising:
- a video module and a control module, wherein;
the video module determines a region of interest (ROI) in at least one video image received from an endpoint and provides the control module video parameters for the ROI;
the control module designs a CP layout based on the parameters for the ROI and instructs the video module how to manipulate the at least one video image, and how to place the manipulated at least one video image into the CP video image according to the designed CP layout; and
the video module builds the CP video image and sends the CP video image toward a display unit of the receiving 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.

14. A video conferencing system, for adapting a continuous presence (CP) video image, comprising:
-
a plurality of endpoints; one or more region-of-interest (ROI) detector modules that detect an ROI in video images generated by at least one of the endpoints; a control unit comprising a control module that designs a CP layout based on parameters of the ROIs and instructs one or more editor modules how to manipulate the at least one video image, and how to place the at least one manipulated video image in the CP video image according to the designed CP layout. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 25)

23. A method for adapting a video conferencing continuous presence (CP) layout, comprising:
-
determining one or more regions of interest (ROIs) in one or more video images received from one or more transmitting endpoints; designing a CP video image to be displayed at receiving endpoint based at least in part on the ROIs; building the CP video image from the video images received from the one or more transmitting endpoints; and delivering the CP video image toward a display unit of the receiving endpoint. - View Dependent Claims (24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
