Secure Reliable Transport (SRT) is an open‑source, UDP‑based protocol that overcomes TCP’s latency and jitter issues in long‑distance live streaming by using ARQ retransmission, FEC, and AES/TLS encryption, enabling high‑quality, low‑delay video delivery even in poor network conditions.
The article explains how the Secure Reliable Transport (SRT) protocol, combined with Tencent Video Cloud’s optimized infrastructure, overcame latency and packet‑loss challenges to deliver stable, high‑quality live streams for the 2020 LPL Mid‑Season Cup and other large‑scale events, and describes its broader applications through MediaConnect.
Tencent Cloud Video’s platform, now powering WeChat, Tencent Meeting and Education, tackles pandemic‑driven traffic spikes with multi‑regional data centers, 1,300+ CDN nodes, sub‑300 ms latency, AI‑driven smart encoding, support for AV1/AVS2 codecs and SRT transport, while expanding fast‑live, cloud editing and AI content analysis for future immersive, AI‑generated experiences.
