Abstract
A method of transmitting a digital data stream to a receiver unit. The method includes the steps of modulating a digital data stream in accordance with a modulation technique so as to generate a modulated digital data stream; providing the modulated digital data stream to a transmitter unit operable for transmitting the modulated digital data stream; receiving the transmitted digital data stream by the receiver unit, where the receiver unit generates signal reception data indicating the quality of reception of the modulated digital data stream; and providing the signal reception data indicating the quality of reception of the modulated digital data stream to a quality control processing unit via a communication channel, where the quality control processing unit analyzes the signal reception data to determine if the quality of reception of the modulation digital data stream by the receiver unit is below a predefined level, and if so, adjusts the modulation technique being applied so as to improve the quality of reception by the receiver unit.
