Operation With Extron SME 100 Encoders

For SME 100 stream discovery in the SMD 101 streams browser (see

figure 5

on page 4), the SME 100 must have both

Stream Control and SAP Control enabled to enable SAP announcements. The SME 100 settings are shown below.
From the SME 100 default web page (see the SME 100 User Guide), select the

Encoder Configuration link, then

Encoder Settings to open the configuration dialog shown in figure 6 below.

SME 100 Encoder Configuration Panel (Partial View)

In both the

Stream Control and SAP Control drop-down lists, select Enable. Choose a Destination IP and

Destination Port which avoid conflict with other multicast devices on your network, then enter them into the
appropriate fields.
With SAP Control enabled, the SME 100 stream (Test Pattern 1) is listed by the SMD 101 stream browser in the Extron
folder. To connect the stream, from the browser, drag and drop the stream anywhere on the

Player Controls panel

(see

Play a Stream:

on page 4).

RTSP Multicast (Pull Streaming)

When using RTSP multicast from an SME 100, the SMD 101 must still connect to it using the SME 100 IP address (for
example rtsp://192.168.254.100) rather than the typical multicast IP address (for example rtsp://239.10.193.165).
If the SME 100 is set up for push streaming (Stream Control Enable), the RTSP bitrate is limited to 5 Mbps on startup or
restart. Although it can be higher, it is not recommended.
If higher bitrates are required, only a single stream method should be active.

Push Streaming (Unicast Port Numbers)

In systems with more than one SME 100 encoder using any of the unicast push methods (TS/UDP, TS/RTP, ES/RTP) to a
single SMD 101 decoder, each SME 100 must use a unique port number (such as 60000 and 61000). See the SMD 101
User Guide for additional information.

Multicast

For systems where streams from one or more SME 100s are received and decoded by multiple SMD 101s, multicast
addressing is strongly recommended. All network switches must be suitably rated and correctly configured for IGMP
snooping and multicast filtering with an active IGMP querier (possibly the network switch) available on the local subnet
for optimum performance.
