Abstract
A known system derives information from the VPS- and Teletext signals and displays the title of the current program and the network name on screen for a few seconds, each time a new channel is selected. The VPS- and Teletext signals contain more program-related information than mentioned above. The present invention concerns deriving the end-time and/or the remaining duration of the current program as well as the starting-time of the next program for display on-screen.
