Configure a Multicast Relay with an Auto-Unicast Source

Detailed Use Cases : Configure a Multicast Relay with an Auto-Unicast Source

The VBrick Distributed Media Engine contains a fully featured RTP server, giving the administrator the ability to provide an RTP Relay Multicast stream. When configured, clients will then be able to join the multicast via HTTP to the DME. This example shows how a relay can be streamed from an auto unicast source on a VBrick H.264 encoder.

H.264 Encoder Setup

1. Configure the encoder with a valid Auto Unicast (TCP) stream and then navigate to Program Configuration > Transmitters and configure a transmitter to unicast to the DME.

2. Configure the transmitter with the following settings:

a. Set the Auto Unicast Dest Port to the RTSP port of the DME.

b. Configure the Auto Unicast Dest Pub Point Name to the desired sdp file name. This .sdp file will be automatically placed in the root folder. (Note: The file name must be appended with .sdp or the auto unicast will fail.)

c. Enable the transmitter and verify it is sending to the DME.

DME Setup

1. Create a new RTP Relay. See: Create or Edit an RTP Relay.

2. Play the Multicast Relay using QuickTime with a URL in the following format. http://<dme_ip_Address>/<testmulti2.sdp>

If desired, a URL can be added to the VBrick's external Announce Settings on the Program Configuration > Transmitters page.
