A system for communication between a television set top box (226) and a service provider (209) using a remote base unit (200), which connects to a public telephone network (207) through a standard phone jack (205). This system removes the requirement for dedicated wiring between such a base unit (200) and set top box (226). This invention provides the capability of communicating between a set top box and a remote base unit using either AC power line communication channels (223) or over-the air RF communications (425). Moreover, this invention includes an embedded transceiver (130, 133) into the set top box (226) and includes a modem (203), and associated telephone interface circuitry, into the base unit (200). This invention is particularly adapted to the set top box to base unit communication channel useful in satellite pay-per-view systems, internet service provider connections, video storage and routing system, direct broadcast set top boxes and other products and services for sending and receiving such information as program guides, stock quotes, and other types of data used in connection with set top boxes. |
