A set top terminal for receiving information transmitted from a service provider, for receiving control information transmitted by a service provider, and for transmitting control information from the set top terminal to the service provider to interactively control the services that are being received. The set top terminal receives display images via an information channel carrying both conventional analog cable television signals and digital television signals. Additionally, set top terminal control signals are sent from the service provider via a command channel and the set top terminal sends control signals to the service provider via a back channel.
