A computer-implemented control method for a rented television 100 comprises receiving at a digital signal receiver 102 broadcast permission data which has been broadcast over a digital broadcast medium. A permission data file is accessed and validated. Dependent upon the outcome of the validation an operation is performed by permission control unit 106 to restrict or enable functions of the television receiver. The method may be used to remotely disable rental television receivers for which no rental payment has been received. The restriction may serve to render the display 110 and/or audio functions inoperable. Also disclosed is a control system for a rented television which is capable of supporting the steps of the above method. |
