Abstract (en)
The invention which is the subject of this application relates to use of a data transmission system of the sort which is currently used to allow digital data relating to television programmes to be transmitted from a broadcast location, via satellite (6), cable or terrestrial transmission systems to be received by at least one receiver in a premises. The receiver (10) is typically connected to a display screen (14) to allow the display of television programmes generated from the transmitted data. In this invention, the receiver (10) is connected to a further item of apparatus at or in the vicinity of the premises and the control of said further apparatus is achieved via the receiver (10). Operating commands are issued by the receiver (10) and are generated in response to flag data which is transmitted along with the other data and the receiver (10) is capable of reacting to the said flag data and sending a control command to the further apparatus. The flag data can also be used to indicate information data which can be further processed by the further apparatus as controlled by the receiver (10). <IMAGE>
