Why do IPTV channels have different delays compared to live broadcast?

IPTV streams often run behind real live broadcast because of HLS segment buffering, transcoding delays, CDN propagation, and stream stabilization mechanisms. IPTV providers sometimes add 15–60 seconds of delay to prevent buffering and ensure stable playback. Low-latency HLS or DASH formats reduce delay but require stronger infrastructure. Glanfy recommends providers with optimized low-latency delivery for sports events.
