The device generates a reference image of a transmitter logo during a transmission without advertising in a learning mode by separating the constant image part containing the logo from moving image components and characterizing the area containing the logo. An independent detection mode involves comparing the defined image area with the reference image and generating a signal for suppressing advertising transmissions and/or changing channels.
