Abstract

A method and apparatus for "piggy backing" a FAX transmission on a video call. A document, in the form of modulated facsimile data, is received from a machine located in proximity of a sending station. The document is demodulated, packetized and a header, indicating that the packet contains facsimile data, is added. The packets are then injected into a digital video stream carrying video conference data bound for the receiving station.
