SELECTIVE DELIVERY OF DATA TO AN APPLICATION, WHERE THE APPLICATION USES THE DATA ONLY IF THE STATUS OF THE APPLICATION CORRESPONDS WITH STATUS INFORMATION WHICH IS CONTAINED IN THE DATA

摘要

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.
