Abstract
In accordance with one example, a presenter device is configured to participate in a collaboration session with one or more attendee devices. A change in an image displayed at a screen of the presenter device is detected and captured to produce a captured image. The captured image is compressed to form a compressed lossless file and first and second compressed lossy files. The compressed lossless file and the first compressed lossy file are transmitted to the one or more attendee devices, and a determination is made as to whether a further change to the image displayed at the screen occurs within a predetermined period of time. The compressed lossy file is transmitted to the one or more attendee devices when no further change to the image displayed at the screen occurs within the predetermined period of time.
