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.
