Abstract
A method is provided for protecting data content against illegal copying. The data content is provided by an entertainment system and is output to output units in an authorized playback environment for playing back the data content. The method includes transmitting the data content in the authorized playback environment from the entertainment system to an output unit, and adding an interference signal to the data content such that, during playback of the data content outside the authorized playback environment a disruption is induced.
