Abstract: A broadcast data receiver system is provided and a method of operating the system. The system includes a first broadcast data receiver (BDR) (2) located at a first location, typically in a premises. The BDR (2) receives video, audio and/or auxiliary digital data broadcast from a remote location via cable, satellite or terrestrial means. The BDR processes the data and displays the processed data on a display screen (10) and/or audio data via speakers connected thereto. At least a second broadcast data receiver (8) is provided at least a second location typically in the same premises. One of the first and second BDRs (2, 8) is made functional by a signal received from the other of the first and second BDRs, via a telecommunications line (4) provided in the premises and connecting the first and at least second BDRs together, thereby ensuring that both BDRs are connected before operation of the two BDRs can be achieved.

Abstract: A broadcast data processing apparatus and method by which at least first and second set top boxes can only both be rendered operable when at a common authorised location, thus preventing the use of one of the set top boxes at an unauthorised location. The set top boxes are connected to a common link unit via which a tone signal can be transmitted between the set top boxes. At least one of the set top boxes is inoperable until the said signal is received via the link unit and is therefore required to be at the authorised location to be operable.
