What is H5Live?

nanoStream H5Live is a unique delivery and playback technology working on all HTML5 browsers. It is a unique development by nanocosmos based on existing HTML5 / streaming technologies like HLS, fMP4, and Websockets; dependent on the target device and browser, the stream format is automatically chosen.

nanoStream Webcaster is connected to the camera side, to ingest a live stream into nanoStream Cloud for delivery.
