Frikanalen provides its schedule in many formats, and I suspect one of them can be used by this add-on to show what is currently being broadcasted on Frikanalen. I suspect the XMLTV version available from http://beta.frikanalen.no/xmltv/ might be the best option, but it is also available from the API, http://beta.frikanalen.no/api/ , and two web pages http://beta.frikanalen.no/calendar/ and http://beta.frikanalen.no/guide/ .
