A master subscriber station is provided that supports a relatively low cost slave subscriber station. The slave subscriber station relies upon the master subscriber station for certain functions and therefore can be implemented as a lower cost design. Duplication of functionality is therefore minimized, resulting in lower complexity and lower overall costs. The master subscriber station has the ability to process multiple video streams such that one or more of the additional streams can be sent via coaxial cabling to a slave subscriber station, as well as receive and process user control signals from the slave subscriber station. The slave subscriber has the ability to receive and demodulate video and audio streams sent by the master subscriber station, as well as send user control commands back to the master subscriber station over the same coaxial cable that delivers the video streams to the slave subscriber station.
