Also called: TV guide, Electronic Programme Guide.
An EPG lists programmes by channel and time, usually as a grid you can scroll through. Selecting a programme shows its title, description and start time, and on channels with catch-up you can often jump back to a show that has already aired.
IPTV services publish guide data for their channels, and the player app downloads it in the background. Many apps use the XMLTV format for this, either loaded automatically with an Xtream Codes login or added separately as an EPG URL next to an M3U playlist.
If the guide shows the wrong times, the cause is almost always the time-zone or time-shift setting in the player app rather than the guide data itself.
How does EPG apply to Veloplaylist?
Veloplaylist includes a full TV guide (EPG) on every plan; it loads automatically in apps that support Xtream Codes logins.
For background and history, see EPG on Wikipedia.
