Play a DME Stream
DME Input and Output Stream Overview
DME input and/or output streams can be configured to play on desktops (with a variety of
players), set top boxes, and mobile devices at different locations and in a variety of different
physical configurations. The DME supports live RTP, Transport Stream, RTMP (Flash), HLS,
and HDS streams. It also functions as a progressive download server for .wmv and other files.
Stored VOD files are supported by the onboard RTP and Multi-Protocol VOD servers and
added to the DME via FTP. To play these streams you will need a corresponding player.
Often these players are available either as standalone players or embedded into a Web
page.
Table 1. DME Protocol Types and Players
Play an RTSP/RTP Stream
Live or stored RTP streams are playable via unicast in Vbrick StreamPlayer, Apple
QuickTime, VLC, and other players using RTSP for stream control. An RTP player can also
be embedded on an HTML page. It is possible to utilize either the Multi-Protocol Server or
the RTP server to play these streams.
For live content, the RTP server should be used for optimal stream stability, but if many
simultaneous users are expected, the equivalent RTSP server from the Multi-Protocol Server
is preferred. Regardless of the server used, to play the live stream an RTSP URL in the
following format points to the stream:
rtsp://<dme_ip_address:port>/<publishing point>
When using the RTP server the port does not need to be identified unless it has been
changed from the default 554. Normally, the publishing point format is <streamname>.sdp
so, a URL would look like:
rtsp://<dme_ip_address>/vbStream1S1.sdp
When using the Multi-Protocol server, the port does need to be identified. The publishing
point is the stream name so, an example URL would be:
Protocol Typical Players

SDP/RTP H.264 StreamPlayer, QuickTime, VLC
