What does XMLTV mean?
XMLTV is a structured XML format used to exchange television channel and programme-listing metadata. It can describe channel identities, programme titles and scheduled times, but it does not supply the underlying live video or an archive recording.
Why it matters
A player needs to retrieve the guide, parse it and match its channels to the loaded media catalogue. Those are separate stages, and success at one does not guarantee success at all three. The guide’s coverage window and update schedule also affect what appears. Correct time interpretation matters when programmes are displayed in a different local zone.
