XMLTV / applied guide-data decisions · Primary-source explanation; no UK IPTV implementation or account test. Instructions are based on publisher guidance; a UK IPTV account was not tested on this platform.
Separate missing information from a positive claim
A programme entry without previously-shown should not be converted into a claim that it is a global first broadcast. XMLTV’s comments explicitly preserve that uncertainty. A source may not know the earlier transmission or may simply omit the field. Keep no repeat information as that limited state rather than turning it into new everywhere.
Read the publisher’s actual explanation
The same DTD explains that premiere can mean different things to different channels and allows explanatory text. A first showing on one channel or in one country is different from a first release anywhere. Preserve the supplied explanation when a consumer displays only a short badge, especially if that badge would otherwise imply a stronger claim.
Apply the distinction to a hypothetical listing
Imagine a film made several years ago is labelled as a premiere on one broadcaster. Its age and that local label can coexist without either being an error. The useful question is what this broadcaster means in this listing. Do not change the film’s production date or invent a new episode identity just to make an unqualified badge appear consistent.
Use the labels for the right decision
When choosing a recording, confirm the title, edition, episode information and scheduled transmission rather than relying only on a new or premiere indicator. Report a misleading abbreviated display with the original source text. This case explains metadata scope and missing-data logic; it does not establish any UK IPTV programme’s first showing, catalogue freshness or content rights.
