The invention concerns a method of transmitting video data comprising information bits, a video processing unit with a control unit for sending andor receiving such video data, and a computer program product for the execution of said method. A mobile device obtains at least one point of interest among a starting location and a finishing location for a trip. Signals can be classified based on the abstracted design as either transient, temporary, or persistent. In scan mode, one or more elements which normally function as master elements, function as slave elements.
