External modules with optional features for a dual-tuner set-top terminal and method of implementing same

摘要

A system of flexibly implementing a set-top terminal for connection of a subscriber's electronic equipment, such as a television set, to a cable network in which a base set-top terminal can be connected to one of a number of different modules. Each module provdes a different function or set of functions when connected to the base set-top terminal. This allows the terminal system to flexibly provide exactly that function or combination of functions needed or desired by a subscriber while standardizing manufacture of the base set-top terminal. The need to produce a range of set-top terminal models is eliminated.
