Abstract

A narrow bandwidth broadcasting system for transmission of video and television via low bandwidth medium such as internet or radio links. To save bandwith, video scenes are separated into foreground and background objects and only foreground objects are sent to the viewers. However, graphical model or real image may be sent as a reference background and updated according to its own movement. The broadcast system also captures the video camera identification, position, orientation and field of view size for each video fields and sends it together with the foreground object to the viewer. The broadcast system also includes an object tracking apparatus, which captures the position in space of objects that appear in the scene. Shuch parameters allow the implementation of a 3-dimensional rendering at the receiver side.
