Every IPTV subscription comes with a small vocabulary — this page defines all of it in plain English. Bookmark it: the terms below cover everything you'll meet while choosing a service, setting it up, and getting the best picture out of it.
IPTV (Internet Protocol Television)
Television delivered over an internet connection instead of cable, satellite or antenna. Channels arrive as data streams, which is how one subscription can carry 25,000+ channels, on-demand libraries and 4K — the full explanation is in What is IPTV?.
Xtream Codes login
The most common IPTV login format: a server URL, username and password. Entering these three details into any compatible player app loads your channels, guide and VOD automatically.
M3U / M3U playlist
A plain-text playlist file listing every channel URL in a subscription. The older alternative to an Xtream Codes login — same content, clumsier to manage.
EPG (Electronic Program Guide)
The on-screen TV guide showing what's playing now and next on every channel. A premium service supplies accurate EPG data for Canadian channels across all time zones.
VOD (Video on Demand)
The movie-and-series library included with a subscription — content you start whenever you want, like a built-in streaming platform. MapleStream's library exceeds 170,000 titles.
Catch-up TV
A rolling multi-day archive of what already aired on a channel, letting you rewind the schedule — watch last night's game or yesterday's newscast without recording anything.
MAC-address activation
An activation method used by TV apps (IBO Player, Smart IPTV): the app shows a unique MAC address, the provider links your subscription to it server-side, and no typing of logins on a TV remote is needed.
Buffering
Playback pausing while the player waits for data. Caused by slow Wi-Fi, VPN detours, or an oversold server — the 7-check buffering guide isolates which.
Anti-freeze technology
Provider-side techniques — redundant sources, adaptive bitrate, extra peak capacity — that keep live streams smooth when demand spikes, like playoff overtime.
H.265 / HEVC
The video compression standard behind modern 4K streaming: half the bandwidth of older H.264 at the same quality. Any Fire TV Stick 4K or recent Smart TV decodes it in hardware.
4K60 (4K at 60 fps)
Ultra-HD resolution at 60 frames per second — the standard that makes fast sports look fluid. Requires roughly 25 Mbps of internet bandwidth per stream.
Multi-connection
The number of devices that can stream simultaneously on one subscription. A household plan needs at least two; check the count on the pricing page.
PPV (Pay-Per-View)
Event broadcasts — UFC numbered cards, boxing — traditionally sold at $60–$80 each. Premium IPTV services include PPV event channels in the subscription.
Blackout
A regional restriction that blocks a live game in certain markets on traditional TV. IPTV feeds carry every regional broadcast, which is why out-of-market games remain watchable.
STB / set-top box emulation
Apps that make a Smart TV or stick behave like a dedicated IPTV receiver (the 'portal' style used by MAC-activated apps) — modern services support both this and playlist logins.
Adaptive bitrate
Automatic quality adjustment that steps a stream down (and back up) to match your available bandwidth moment to moment, trading sharpness for smoothness instead of freezing.

M3U vs Xtream Codes — what's the difference?
Same channels, different plumbing: M3U is a manual playlist file; Xtream Codes is a three-field login the app uses to fetch everything itself. Use Xtream Codes when offered.
What does EPG mean?
Electronic Program Guide — the on-screen schedule. If a provider's EPG is wrong, its infrastructure is neglected; it's one of the eight things to test in a trial.
