once it has started. Uncheck only if you have knowledge of the source and the RTCP
reports it sends.
6. Enable the stream and apply, and the DME will start acquiring the stream. This stream
can now be redistributed by the DME.

This protocol is not supported in DME 3.x.

This input is sourced from a unicast or multicast transmitter on a Vbrick 7000/9000 Series
(H.264) encoder or equivalent source. In this scenario, a transmitter is configured to send a
live unicast stream (e.g.
172.xxx.xxx.xxx
) to the DME or a live multicast stream (e.g.
239.xxx.xxx.xxx
) to a multicast address.
For both of these options you will need to manually fetch the SDP file from the encoder and FTP it to
the root folder (or a subfolder) on the DME.
The SDP file has information describing the stream
such as profile, bit rate, addressing, and transmission method.

To stream from a Vbrick encoder:
1. Launch the VBAdmin page for the encoder.
2. Go to the Program Configuration > Transmitters page.
3. Click on the
SDP File URL
button.
4. FTP the SDP file to the root folder (or a subfolder) on the DME.
When configuring the encoder, the default Video Port is 4444; the default encoder Audio
Port is 4644. These ports must be unique for each stream and must match those configured
in the DME. The DME administrator must ensure that all SDP files have unique port
numbers and that no port numbers are duplicated across all SDP files. Subsequently the
encoder must also be configured to transmit on unique ports when streaming to the DME.
Note : In order to redistribute a stream via any of the mechanisms sourced
from a multi-protocol server, an RTSP pull (In-6) must be configured
between the RTP streaming server and the multi-protocol server
Similarly, if this input mechanism is used to source a transrating operation,
the RTSP Pull must be set up. Announcements need manual configuration if
this input mechanism is used.
