Setting up and navigating IPTV involves a distinct set of acronyms and technical terms. This glossary provides straightforward, plain-English definitions of the terms you will encounter most frequently.
Core Acronyms
IPTV (Internet Protocol Television)
The delivery of scheduled television programming, catch-up broadcasts, and on-demand video over an internet network protocol rather than conventional terrestrial aerials, cable television, or satellite signals.
M3U & M3U8
A plain text playlist file format that contains a catalogued list of web URLs pointing to individual media streams. An M3U8 file uses UTF-8 character encoding, making it ideal for international character sets and channel names.
EPG (Electronic Programme Guide)
The interactive on-screen timetable grid that displays what programme is currently broadcasting on each channel, what is scheduled next, programme summaries, and start/finish times.
XMLTV
The standardised XML-based file format used to distribute EPG schedule information across the internet to compatible IPTV player applications.
Xtream Codes API
A widely adopted server-side management and client login protocol. Instead of manually pasting lengthy M3U web addresses, users simply enter a Server URL, Username, and Password into their player app.
Video & Network Terms
Bitrate
The volume of data transferred per second to render a video stream, typically measured in Megabits per second (Mbps). Higher bitrates retain finer visual fidelity and reduce compression artefacts during high-motion scenes like live football.
Codec (H.264 / HEVC H.265)
The digital compression algorithms used to shrink video files for efficient network transmission. HEVC (High Efficiency Video Coding / H.265) compresses video twice as efficiently as older H.264 codecs, enabling 4K streaming at manageable bandwidths.
Buffering
A temporary pause in video playback that occurs when your streaming device empties its cached memory buffer before new data packets arrive from the host server.
Latency
The elapsed time between when an event occurs at the broadcast source and when it displays on your home screen. IPTV streaming typically incurs a modest 15–40 second latency compared to direct terrestrial radio frequency broadcasts.
VOD (Video on Demand)
Non-live media libraries (movies and television series) stored on servers that users can initiate, pause, rewind, and resume at any time.
