What Is Xtream Codes API?

Xtream Codes is the most common server management system used by IPTV providers. When you subscribe to IPTV, your provider gives you three pieces of information:

Your IPTV app uses these to authenticate with the server, download your personalized channel list, EPG data, VOD library, and series catalog — all in one request. This is why Xtream Codes setup is faster and more feature-complete than M3U URL setup.

Frequently Asked Questions

IPTV encodes live TV into H.264 or HEVC digital streams, packages them as data packets, and delivers them over the internet via HLS or TS protocols. Your IPTV app buffers, decodes with hardware acceleration, and plays the stream on your screen in real-time.

HLS breaks the stream into small buffered segments over HTTP — reliable on variable connections. UDP sends raw packets with no guaranteed delivery — lower latency but can drop frames. Most IPTV services use HTTP/HLS or TS for reliability on consumer internet.

IPTV providers run dedicated media servers with Xtream Codes API or similar software. Servers handle channel encoding, user authentication, EPG data, VOD storage, and stream delivery via CDN infrastructure.

The app connects to your provider's server with your credentials, downloads the channel list and EPG, and when you select a channel it sends an HTTP request for that stream and plays it using ExoPlayer (Android) or AVPlayer (iOS) with hardware decoding.

SD: 3–5 Mbps. HD 1080p: 10–15 Mbps. 4K: 25–50 Mbps per stream. For multiple simultaneous streams, multiply accordingly. Wired Ethernet is recommended for 4K stability.
