    Abstract: In particular, the present invention provides a method and system for conferencing, including the steps of connecting at least two sites to a conference, receiving at least two video signals and two audio signals from the connected sites, consecutively analyzing the audio data from the at least two sites connected in the conference by converting at least a part of the audio data to acoustical features and extracting keywords and speech parameters from the acoustical features using speech recognition, and comparing said extracted keywords to predefined words, then deciding if said extracted predefined keywords are to be considered a call for attention based on said speech parameters, and further, defining an image layout based on said decision, and processing the received video signals to provide a video signal according to the defined image layout, and transmitting the composite video signal to at least one of the at least two connected sites.

    Abstract: A method for automatically determining an orientation and zoom of an image pickup device associated with a video conferencing system, wherein the method includes the steps of: generating, at the image pickup device, an image signal representative of an image framed by the image pickup device; processing the image signal to identify objects plural users of the video conferencing system in the image; steering the image pickup device to an initial orientation; determining a location of all the identified objects relative to a reference point and determining respective sizes of the identified objects; defining an area of interest in the image, wherein the area of interest includes all the identified objects; and steering the image pickup device to frame the defined area of interest including all the identified objects where a center of the frame substantially coincides with a center of all the identified objects.
