Quick Answer
Key Takeaways (Google Snippet)
This definitive glossary covers every essential IPTV acronym: EPG (Electronic Program Guide), VOD (Video on Demand), M3U (Playlist link format), Xtream Codes (API credentials format), and HEVC (High Efficiency Video Coding).
■ Table of Contents
Glossary A – F
- Adaptive Bitrate Streaming (ABR): Technology that dynamically adjusts video quality in real time based on available bandwidth, preventing stream stops.
- Bitrate: The amount of data processed per second, measured in Megabits per second (Mbps). Higher bitrate equals sharper video clarity and less compression artifacting.
- Buffer: A temporary storage reservoir in your device's memory that downloads a few seconds of video ahead of the playhead to smooth out micro-drops in Wi-Fi speed.
- Catch-Up TV: An interactive feature allowing subscribers to replay past live television programs up to 7 to 14 days after the original broadcast.
- CDN (Content Delivery Network): A worldwide network of proxy edge servers that cache video streams close to end-users to reduce latency and eliminate buffering.
- EPG (Electronic Program Guide): An on-screen interactive schedule showing past, current, and upcoming TV shows, usually loaded via an XMLTV URL.
- FPS (Frames Per Second): The frequency at which consecutive images are displayed. Standard TV is 30FPS, while live sports streams on strongiptv broadcast in fluid 50FPS or 60FPS.
Glossary G – M
- HLS (HTTP Live Streaming): Apple’s modern protocol that segments streams into small HTTP download chunks.
- HEVC (H.265): High Efficiency Video Coding. Compresses 4K video 50% more efficiently than older H.264 codecs.
- Jitter: The variance in latency between data packets. High jitter causes audio-video desync and micro-stuttering.
- M3U / M3U8: A text-based playlist format listing media stream URLs and channel metadata encoded in UTF-8.
Glossary N – Z
- Time-Shift: The ability to pause, rewind, or restart live TV broadcasts currently in progress.
- Unicast: One-to-one transmission between an IPTV server and a single user's device.
- VOD (Video on Demand): Instant access to an on-demand library of films, TV shows, and documentaries with full playback controls.
- Xtream Codes API: A standard REST API used by IPTV players to log in via Username, Password, and Server URL, auto-populating channels, categories, and EPG schedules.
Frequently Asked Questions (FAQ)
Why is my EPG guide showing 'No Information'?
EPG guides update every 24 to 48 hours. In your player settings (like TiviMate), select 'Update EPG' or confirm your time zone offset matches your location.
What does 60FPS mean for sports?
60 frames per second makes fast-moving objects like footballs, hockey pucks, and race cars look sharp and smooth rather than blurry.
