Setting > Live Stream Setup - Protocols
It is always preferable to decide what stream setting best matches your purpose of use
as well as the network and protocol before streaming video via NVS-25.
HLS Protocol
Use NVS-25 to feed IP video stream to several Apple computer clients or tablet
computers such as iPad, iPhone or MacBook running Safari browser. HLS feeds video
and audio streams to the iOS devices. Note that, depending on the settings chosen,
HLS latency may be up to 10 seconds in case of live events.
RTSP Protocol
Use NVS-25 to feed IP video stream [TCP , HTTP] to a small group of clients on a Local
Area Network (LAN) or Wide Area Network (WAN). The user can then view the video via
free client software such as VLC Player. However RTSP does not work well with
some tablet computers.
RTSP is open for viewing by anyone on the same network
with the streaming details or link. It can be sent across the internet, but each client
added will add data loading to NVS-25, as each video stream is set up individually
for each client.
RTSP has a limitation of three viewing clients before NVS-25 becomes
congested and video stream fails.
RTMP Protocol
Use NVS-25 to deliver a single IP video stream [TCP] to a server on a Wide Area
Network [WAN] like the
internet
(RTMP Publish) or to a small group of clients on a
private Local Area Network [LAN] (RTMP Local).
The server on the WAN could be the server of a Content Delivery Network [CDN],
