It's a plain text list, either M3U format or the Xtream Codes API format, made up of lines pairing a channel name with a stream URL and sometimes a logo or category tag. Your provider builds this file from its server; you are not creating it yourself. A player app reads the list, shows you channel names and logos, and only requests the actual video data the moment you tap a channel. The list itself is a few kilobytes; the video it points to is not. That size difference is why downloading or refreshing the list is near-instant even on a slow connection, while the streams it points to are the part that actually needs steady bandwidth to play smoothly.

Traditional TV tuners scan the airwaves or a cable line to find signals automatically. IPTV doesn't work that way: your provider hands you a pre-built playlist, and the player app loads that list directly rather than searching for anything. "Channel scan" is a feature people coming from cable or satellite ask for by habit, but it doesn't map onto how playlist-based streaming works, since there's no signal to sweep for in the first place. Loading the correct list, or hitting refresh on an app that already has one saved, is the equivalent step, and it happens in seconds rather than the minute or two a real tuner scan takes.

You enter your account's playlist URL, or an M3U link plus login details, into a player app such as TiviMate, IPTV Smarters, or STBEmu, and the app pulls the full channel list in one step. Some apps store the URL and re-fetch the list automatically each time you open them, which is how new channels or removed ones show up without you doing anything manually. On most setups this whole process, from opening the app to seeing every channel populated, takes well under a minute, and you only have to enter the login details once per device, not once per channel or per group.

Yes, and it's a real, separate configuration step rather than something that happens on its own. The program guide, the EPG, can come bundled with your channel list or from an independent EPG feed, and some setups mix an M3U channel list with a separate Xtream-format EPG source. If your guide shows the wrong show times or blank listings, check whether the EPG source is actually pointed at the right feed before assuming the channel list itself is broken. This trips people up specifically because the channel list and the schedule data can be updated on different timelines by different systems, so one working correctly doesn't guarantee the other is too.

Ask how the list is delivered (M3U link or Xtream login), whether it updates automatically, and whether the provider's total includes VOD titles counted alongside live channels, since a mixed number inflates the live count. IP4KTV's 54,000+ live channels and 219,577+ VOD titles are tracked as separate figures for exactly that reason, rather than one combined headline number. A provider that won't say how the number breaks down, or that only shows a screenshot of a list instead of letting you check it yourself, is one to be careful with. A short trial period is the fastest way to see the real list before committing to a longer plan.
