Abstract
A method and system for robbing bits in an ATM channel for forming a robbed bit stream. Unused portions of the header in an ATM cell stream are robbed to form a new robbed bit stream. Information is inserted into the new robbed bit stream and sent to a service area. The information in the robbed bit stream is then extracted and input into information appliances in, for example, homes. The information in the robbed bit stream can include an additional video channel, a program guide or other information.
