<p>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.</p> |
