Abstract
Subscriber apparatus for a cable television system or the like comprises a converter/descrambler and a programmable remote control. All authorization data for premium services and features a subscriber is entitled to receive are stored in the remote control. Program/interface apparatus is provided to enable a subscriber to request additional premium services or features, such as pay-per-view programming. Authorization data for the requested services or features are transmitted by the program/interface apparatus to the remote control via an infrared signal path. A similar signal path is used by the remote control in controlling the converter/descrambler to provide the authorized services and features, such as the descrambling of a premium television channel.
