Seamlessly Compatible with dvCloud

Get the most out of your streaming hardware using DVCloud. The NVS-33 is seamlessly compatible with Datavideo’s DVCloud service. This subscription service give you the possibility of sending your stream to multiple destinations at the same time without having to have multiple hardware encoders. You can also record your production on the DVCloud platform in h.264 format. After recording you can directly use this recording to upload it to your favourite content platform. Direct SRT streaming to dvCloud prevents hickups and lag in your stream, especially when using slow or unreliable internet connections or when streaming large distances (for instance to the other side of the globe). Even if your destination does not support SRT you can still stream SRT to dvCloud and go to the destination in RTMP. For more information on DVCloud, please visit the product page or sign up directly on www.dvcloud.tv
Support SRT streaming protocol, no need to worry about unreliable network environment

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.

Stream to 25 Platforms Simultaneously (dvCloud Professional)

dvCloud Professional (please refer to www.dvcloud.tv for more info) can stream to 25 platforms simultaneously. It can stream to either different platforms or different channels of the same platform. Thus, even if your local network bandwidth is limited, you can still stream to multiple platforms at the same time with dvCloud.

Real Time Statistics

dvCloud provides powerful real-time statistics for all video sources and destinations so you can be sure every frame reaches its destination:

  • Monitor your video sources and be sure every frame makes it to the cloud
  • Leave nothing to chance, check your networks performance and adjust your streaming settings before you go live
  • Monitor your NVD-3X MARK II decoders and be sure every frame makes it to the decoder
  • Monitor your streaming destinations in real time with our easy-to-use traffic light system
  • All statistics are graphed, you can see the previous 10 minutes statistics.

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.
