A videoconferencing system uses a modular terminal that includes a conventional digital still camera coupled to the input port of the videocommunicator, such as a set top box. There are various features provided by this arrangement, including using the digital still camera to present video information to the videocommunicator with a split screen image representing the still image, a receiver arrangement permitting the digital still camera to fit securely and adjacent to the videocommunicator, and pan/tilt/zoom camera features provided electronically.
