System, device and methods for transmitting and receiving location dependent data

Abstract

The invention relates to a system () for transmitting location dependent data. The system comprises multiple antennas (), a transmitter () coupled to the multiple antennas () and a processor (). The processor () is configured to determine multiple location dependent parts of the location dependent data, each of the multiple location dependent parts corresponding to a different geographical region (-), and to use the transmitter () to transmit at least two of the multiple location dependent parts to a different target location (-) over the multiple antennas (). Each of the at least two location dependent parts is associated with a different reference location (-) and the distance between a target location (-) and a reference location (-) associated with a location dependent part transmitted to the target location (-) is smaller than a predetermined threshold. The invention further relates to a device () for receiving location dependent data. The device () comprises a receiver and a processor. The processor is configured to use the receiver to receive a broadcast data stream comprising a first location dependent part of the location dependent data and a first identifier identifying the first location dependent part at a previous instance and a second location dependent part of the location dependent data and a second identifier identifying the second location dependent part at a current instance. The processor is further configured to detect a difference between the first identifier and the second identifier and to disregard the first location dependent part when the difference is detected. The invention further relates to the methods performed by the system and the device and a computer program product enabling a computer system to perform any of these methods.
