Support SRT Streaming Protocol, No Need to Worry about Unreliable Network Environment
Many broadcasters have experienced pixelated video during live streaming, often due to unstable network environments caused by bandwidth volatility. Streaming RTMP over unreliable, low-bandwidth networks can cause issues. With dvCloud, you can now replace the RTMP protocol with SRT, which will fix most streaming issues you may have. SRT is better than RTMP because it handles problematic networks more efficiently. It requires less bandwidth, and it solves data errors faster. As a result, your viewers will experience a better stream, with less buffering and pixelization.

Build a Reliable SRT Live Streaming Workflow with All Datavideo Products
Datavideo's wide range of encoders, cameras, and hand-carry switchers are fully supported by SRT and dvCloud. Datavideo encoders and dvCloud provide reliable streams over unreliable networks. By using a Datavideo encoder and dvCloud together, you can utilize SRT (instead of RTMP) on the initial problematic connection or "First Mile." After your video stream reaches dvCloud, you can depend on dvCloud's reliable, high-bandwidth network to deliver the stream to your favorite destinations, like Facebook and YouTube.
