Article FAQs

What protocol does IPTV use?

IPTV primarily uses HTTP/HTTPS or RTSP protocols for unicast streams, and IGMP/UDP for multicast enterprise distributions.

Why does IPTV buffer sometimes?

Buffering is usually caused by internet latency, ISP bandwidth throttling, or overloaded edge CDN nodes. Using a high-speed server prevents this.
