on the channel, signaling an Hbbtv services.
2) TV or setup boxes supporting the standard (HBBtv) and are
connected to the internet, will show a red-button icon on the tvscreen.
3) When the user actives the red-button, the TV displays a Hbbtv
page from drdk with content from dr.dk and on demand video.
