<p>A method is suggested for detecting a change in the status of a data source the signal of which is recorded beginning at a first time and reproduced beginning at a second time which is later than the first time. In order to prematurely inform a user about unwanted changes in the data stream originating from the data source while reproducing recorded content, the signal to be recorded from the source is permanently monitored for properties indicating an unchanged data stream. Upon detecting a change in the data stream the user is informed, e.g., via an on-screen-display. A menu offering options for further operation or correcting a possible fault is provided to the user. Further a device incorporating the method is suggested. <IMAGE></p> |
