retransmitted. If overhead is not a factor, TCP is recommended. See the "Auto Unicast
Mode" topic in the Vbrick 9000 Encoder Admin Guide for more information. In addition,
please keep the following points in mind when configuring this input method:
• If using UDP (IN-3), the DME chooses the audio and video ports. The default DME
Auto Unicast Destination Port = 554.
• If using In-3 or In-2 and Flash Server Authentication is enabled on the DME Security
page, you will need to configure an Auto Unicast Destination Username and Password.
• This input method has the desirable characteristic that no input configuration is required
on the DME so the stream name is generated by the stream configuration parameters on
the source side. This name must be unique in the DME. derived from two encoder
parameters which must be configured to be consistent. One of these is the sdp file name.
The second name source is the incoming program name. In some cases, multiple streams
with different bit rates are to be sent to the DME. In these cases, the unique program
names are preserved using the Announce Session Name Override parameter to override
the common program name.
Figure 1. Encoder Auto Unicast Listener
To configure an RTSP announce (RTP) input:

Objective: Send a unicast set of streams via Auto Unicast to the DME as input. RTP streams
can be generated either by an encoder or another DME, and the corresponding SDP file
describes the RTP stream(s).
Configure your encoder as follows:

1. Set the desired Audio/Video configuration for frame rate, resolution, video and audio
rate, sampling frequency etc.
2. Select a stream to send, set the stream type to RTP, and select the streams you want to
send to the DME (including audio, video, or both).
3. Select a transmitter to use for the selected stream and setup the information to send the
stream out to the DME. Select either auto-unicast UDP or auto-unicast TCP. If
transmitting to the Multi Protocol server, only TCP may be used. The destination port,
must be the Multi-Protocol or the RTP Server port as configured on the DME. The
destination of the stream is the IP address or hostname of the target DME. Do not use
