To configure a serve (RTP) output:
Objective : This use case explains how to allow a stream acquired through use case In-8 <
Unicast/Multicast RTP or In-3 < RTP Auto Unicast, or most commonly via an internal Push
form the Multi Protocol server (Out-10), to be served via an RTSP server from the DME to
clients that support RTSP streams. Additionally this server is commonly used for delivering
VOD content.
1. From a client that supports RTSP RTP streams, enter the RTSP URL, typically
rtsp://
dme_ip_address/streamname.sdp
where the
streamname.sdp
file is the original output
SDP file name.

To configure a Push TS output:
Objective : This use case explains how to distribute available streams to unicast or multicast
Transport Stream destinations. Note that although any stream available to the Multi-
Protocol server can be distributed as a Transport Stream, if it is required for KLV
metadata, the stream must remain in a Transport Stream container in all cases.
1. Enter the destination unicast or multicast address.
2. Enter the destination port to send the stream to.
3. Enter the name of the incoming stream you want to distribute to your destination.
4. Enable the stream and click Apply.
5. The status will indicate either “
Sending
” or “
Waiting for Stream
” if the specified input
stream cannot be found.
6. You can also verify the detailed status of your outbound transport stream on the
Monitor> MPS Connections page.

To create an HLS stream for serving via HTTP:
Objective : This use case explains how to create an HLS (HTTP Live Streaming) stream
which is essentially a set of TS files made from an input H.264 stream with a playlist, so that
it can be played on Apple iPad/iPhone/iPad devices via a wireless connection. Mac
QuickTime X players (and some VLC players) can also play the stream.
The playlist generated can either be from a single input stream or multiple input streams.
Multiple streams are useful in varying bandwidth environments. If you need to create an
adaptive playlist that allows the player to switch between multiple rate streams to adapt to the
fluctuating bandwidth, you need to create multiple HLS output streams—all with the same
Master Playlist Name.
The playlist generated can vary depending on the configuration. Since the segments must be
generated on an IDR (Key Frame) boundary, the source must be producing IDR frames at a
regular interval in the stream. It is helpful to know how often IDR frames are being inserted
into stream from the source and it is a good idea to set a Minimum Segment Length that is a
