Abstract
The delivery of data broadcast over a unidirectional communication data link is targeted at receivers having an environment exhibiting a specific characteristic by labelling the data prior to transmission with a status indicator that defines the characteristic that the local environment of the receiver (17) must possess as a precondition for receiving the data. Typical types of characteristics envisaged are the location of the receiver and the climatic condition of the receiver.
