Make Your Streams More Reliable with SRT

Many broadcasters have experienced pixelated video during live streaming, often due to unstable network environments caused by bandwidth volatility and packet loss. Streaming RTMP over unreliable 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. As a result, your viewers will experience a better stream, with less buffering and pixelization.
