RTSP (Real Time Streaming Protocol): Streaming on Moxa VPorts follows the RFC 2326 standard
(http://tools.ietf.org/html/rfc2326
). VPort streaming supports different RTSP connection modes, including
unicast (UDP), unicast (RTSP over TCP), unicast (RTSP over HTTP Tunnel), and multicast.
RTSP keep-alive mechanism: When using RTSP, the Moxa VPort uses the keep-alive mechanism to check
whether the client is still alive or not. For the “SETUP” response, the “timeout” item is inserted into the “session”
header. The value of the “timeout” item is 60 seconds. The client needs to send an “OPTIONS” request to reset
the timeout timer. If the client doesn’t send an “OPTIONS” value of more than 30 seconds, then the MOXA
VPort sends the “SET_PARAMETER” request to the client. The client should respond to the request (“200 OK” is
the usual response, but any response is okay). When the client doesn’t send an “OPTIONS” request or
“SET_PARMETER” response of over 60 seconds, then the MOXA VPort will shut down the client’s connection.
RTSP access naming rule for multiple video streams: An RTSP client player, such as VideoLAN VLC Media
Player, can use the RTSP URL to access VPort.
RTSP URL Syntax Format supported by VPort:
rtsp://<ip address>:<rtsp port>/access Name_(channel index)_(stream index)_(codec yype)
Example: rtsp://192.168.127.100:554/udpstream_ch4_stream1_h264 (test by VLC version 1.1.5)
