Abstract
It is disclosed that in a multicast network environment individual information (10) can be transmitted via a barker channel (12) between a server (2) and an individual end-user device. In the case of digital television services the present invention enables, inter alia, individual information (10) that is addressed to a specific customer to appear on the television screen. This is accomplished by transmitting the individual information (10) via the barker channel (12) from a server (2) to the set-top box (5) via which the television is connected to the access infrastructure. It is also disclosed that an identification number (11) can be added to the individual information (10). In relation to digital television services, the present invention makes use of the insight that set-top boxes already are provided with a unique code. As a result of this, the adding to the individual information (10) of an identification number (11) that is related to the unique code of a specific set-top box (5) enables to individually address set-top boxes.
