Detailed Use Cases : Configure a Multicast Relay with a Unicast Source
  
Configure a Multicast Relay with a Unicast Source
This topic explains how to use the DME to relay an H.264 unicast stream from a VBrick H.264 encoder as a multicast stream. Clients will then be able to join the multicast via HTTP to the DME. This example shows how a relay can be streamed from a unicast source on a VBrick H.264 encoder.
H.264 Encoder Setup
1. Configure a 7000/9000 Series H.264 encoder with a valid RTP stream then configure a transmitter to unicast to the DME (using higher video/audio port values).
2. Navigate to Program Configuration > Transmitters and configure the transmitter with the values displayed below:
 
DME Setup
1. Create a new RTP Relay. See: Create or Edit an RTP Relay.
 
 
2. Configure the RTP Relay as follows:
a. Enter a Relay Name.
b. Set the Status to Enabled.
c. Enter the IP Address as 127.0.0.1 and enter the original .sdp file name.
d. Select Request incoming stream.
e. Enter the Multicast IP Address from the .sdp file.
f. Enter the Output SDP file name.
g. Enter the Video Port value and Multicast TTL.
The user will view the video using QuickTime and entering the HTTP url to the SDP file located on the DME. In the example above the original sdp file is taco-uni.sdp and the output sdp is taco-uni1.sdp. So the URL will be http://172.22.2.50/taco-uni1.sdp.
