Support SRT Streaming Protocol,no Need to Worry About Unreliable Network Environment
Many broadcasters have experiencedpixelated video during live streaming, often due to unstable networkenvironments caused by bandwidth volatility.
Streaming RTMP over unreliable,low-bandwidth networks can cause issues. With dvCloud, you can now replace theRTMP protocol with SRT, which will fix most streaming issues you may have. SRTis better than RTMP because it handles problematic networks more efficiently.
It requires less bandwidth, and itsolves data errors faster. As a result, your viewers will experience a betterstream, with less buffering and pixelization.
Build a Reliable SRT LiveStreaming Workflow with All Datavideo Products
Datavideo’s wide range ofencoders, cameras, and hand-carry switchers are fully supported by SRT anddvCloud. Datavideo encoders and dvCloud provide reliable streams overunreliable networks. By using a Datavideo encoder and dvCloud together, you canutilize SRT (instead of RTMP) on the initial problematic connection or”First Mile.” After your video stream reaches dvCloud, you can dependon dvCloud’s reliable, high-bandwidth network to deliver the stream to yourfavorite destinations, like Facebook and YouTube.
