Key takeaway: Three IPTV terms matter on day one: your login type (M3U, Xtream Codes or MAC portal), the EPG (the TV guide) and connections (how many screens can watch at once). The rest makes sense as you go, and this page explains each one in plain English.
IPTV comes with a lot of jargon. Services send “M3U links”, players ask for an “EPG URL” and forums talk about “anti-freeze” and “HEVC”. None of it is hard once someone explains it in everyday words, and that is what this glossary does.
The terms are grouped by topic, so you can read one section at a time: the basics, logins and playlists, the TV guide and features, picture and streaming, devices and apps, and finally accounts and your network. Each section ends with what the terms mean for you in practice.

How the parts fit together
Before the words, the big picture. Every IPTV setup has three parts:
- The service (provider) supplies the channels, films and TV guide.
- The player app shows them on your screen.
- The device runs the player: a Fire TV Stick, smart TV, phone or computer.
Your login connects the player to the service. Almost every term below describes one of these three parts, or the link between them. For a fuller introduction, read what is IPTV.
IPTV terms: the basics
| Term | Meaning |
|---|---|
| IPTV | TV delivered over the internet instead of cable, satellite or aerial |
| Provider or service | The company supplying channels, films and the guide |
| Player | The app you watch in; it has no channels of its own |
| Live TV | Channels playing in real time |
| VOD | Video on demand: films and series you start any time |
| OTT | “Over the top”: any video delivered over the internet |
| Trial | A short test period before you pay, often 24 hours |
In practice: when an app claims to have “thousands of channels”, it is describing a service, not a player. A genuine player is empty until you add a login.
IPTV terms for logins and playlists
| Term | Meaning |
|---|---|
| Playlist | The list of channels your service gives you |
| M3U | A playlist format, usually delivered as one long link |
| Xtream Codes | A login of server URL, username and password that loads channels, films and the guide automatically |
| Server URL | The service’s server address, usually starting with http:// and ending with a port such as :8080 |
| MAC portal (Stalker) | A login tied to your device’s MAC address, used by MAG boxes and some apps |
| MAC address | A unique hardware ID for your device’s network connection |
| Channel group | A folder of related channels, such as News or Sport |
In practice: ask for Xtream Codes whenever you can. It is easier to type than a long M3U link and fills in the guide by itself. Our guide to M3U vs Xtream Codes explains the difference in detail.
Guide and feature terms
| Term | Meaning |
|---|---|
| EPG | Electronic programme guide: the TV guide grid showing what is on now and next |
| XMLTV | The file format most guides use |
| EPG URL | A link to the guide file, needed with some M3U playlists |
| Time shift | A setting that moves the whole guide by whole hours |
| Catch-up (archive) | Replay shows that already aired, if the service keeps an archive |
| Recording (PVR) | Saving a show to your device’s storage |
| Multiview | Several channels on one screen at the same time |
| Parental control | A PIN on chosen channels or groups |
In practice: if the guide is empty or every show is an hour out, the EPG link or the time shift is the usual culprit. See IPTV EPG setup and IPTV guide not working.
Picture and streaming terms
| Term | Meaning |
|---|---|
| SD, HD, FHD, 4K | Picture resolution, from standard to ultra high definition |
| Frame rate (fps) | Pictures per second; 50 or 60 fps looks smoother for sport |
| Bitrate | How much data a stream uses each second, in Mbps |
| Buffering | Pauses while the player waits for more data |
| Buffer size | How much video the player loads ahead |
| HEVC (H.265) | Efficient compression that saves data but needs device support |
| Decoder | The part of the player that turns data into a picture: hardware or software |
| Anti-freeze | A marketing term, not a standard technical feature |
In practice: higher resolution and bitrate need more speed. Our guide to IPTV speed requirements shows how many Mbps you need, and 4K IPTV covers the extra requirements for 4K.
Device and app terms
| Term | Meaning |
|---|---|
| Fire OS | The Android-based system on most Fire TV sticks; allows sideloading |
| Vega OS | The newer system on some Fire TV models; Appstore apps only |
| Sideloading | Installing an app from outside the official store |
| APK | An Android app installer file |
| Downloader | The Fire TV app most people use to sideload |
| Downloader code | A short number that replaces a long web address in Downloader |
| Android TV / Google TV | Google’s TV systems, with the Google Play store |
In practice: check which system your device runs before you buy. Players such as TiviMate need Fire OS or Android TV. See Downloader on Fire TV.
Account and network terms
| Term | Meaning |
|---|---|
| Connections | How many screens can watch at the same time on one plan |
| Line | Industry word for one subscription account |
| Reseller | A business selling a larger service’s capacity under its own name |
| Auto-renewal | A plan that charges again automatically when it ends |
| VPN | A service that encrypts and reroutes your internet connection |
| ISP throttling | Your internet provider slowing certain kinds of traffic |
| Ethernet | A wired network connection, steadier than Wi-Fi |
In practice: count the screens that watch at the same moment and choose a plan with that many connections. Our guide to IPTV multiple connections explains how. A reliable service also states clearly whether plans renew automatically.
How to use this glossary
Bookmark this page and look up words as you meet them. If a service uses a term you cannot find here, ask them to explain it before paying; a real company with clear terms will answer. To compare services with these words in mind, see our guide to the best IPTV service.

FAQ
Provider or player: what is the difference?

Which login type should I ask for?
Xtream Codes, in most players. It is quicker to type and loads the guide automatically.
What is the difference between EPG and catch-up?
The EPG shows what is on now and next. Catch-up lets you replay shows that already aired, if the service keeps an archive.
