Description

BACKGROUND OF THE INVENTIONThe present invention generally relates to a terminal authorization method and, more particularly, to a method for establishing user friendly authorizations and deauthorizations to control an interactive terminal in a cable television system.Two-way interactive cable television systems are known for transmitting entertainment, information and data signals over a cable facility to a plurality of users. Data may be transmitted and addressed to a particular subscriber over a separate data channel or a so-called "in-band" data channel. In a downstream direction, addressed control data may represent services authorized to a particular terminal or control commands to that terminal. In an upstream direction from a terminal to the service provider or system manager location, control data may represent selections made by a user in response to a polling request or at the time of user selection.One environment in which two-way interactive cable television systems may...
