Abstract
A system for full motion videoconferencing. The total video image space is broken down into regions of such position and size relative to the space that the image data in predetermined sections of the regions is overlapped during the cyclic transmission thereof. The reception and display of the superimposed regions provides a significant increase in the perceived transmission rate in the overlapped sections, rendering those sections suitable for full motion effects.
