The present invention relates to methods, devices, a media signal as well as a recorded medium relating to a media signal having audio samples including a buried data channel ( 30, 32, 34, 36 ). The buried data channel ( 30, 32, 34, 36 ) provided in the audio samples of a media signal includes information about the spectral shape of the buried data channel ( 30, 32, 34, 36 ). In this way data in the buried data channel ( 30, 32, 34, 36 ) can be updated in a simple manner without having to analyse the media signal. |
