Abstract
Systems, methods, and modes are disclosed for live presentation sharing between meeting presenter's and meeting attendees' portable electronic devices during a meeting, and more specifically for viewing presentation content on a portable electronic device displayed on a meeting room display during a meeting. The system comprises a presentation gateway configured for receiving and transmitting presentation content to a meeting room display during a meeting. The system further comprises a portable electronic device that pairs with the presentation gateway. The presentation content is displayed on the portable electronic device substantially in synch with the presentation content displayed on a meeting room display by repeatedly capturing a new image from the presentation content, comparing each new image to a previously saved image to determine whether the new image is substantially identical to the previously saved image, and saving a new image that is not substantially identical to the previously saved image, wherein the newly saved image is displayed on the display of the portable communication device.
