SME 100 Stream Discovery

For SME 100 stream discovery in the SMD 101 stream browser window (see Browser Panel - Streams on page 19), the SME 100 must have both Stream Control and

SAP Control enabled. Figure 49 shows the SME 100 settings. 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 49 below.

		Streaming Configuration
Stream Control	Stream Method	Destination IP	Destination Port	MTU	TTL	QoS (Differentiated Services)
Enable	Multi TS/RTP	238.13.197.190	60000	1500	10	Normal (CS3)

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 session name (Test Pattern 1) is listed in the SMD 101 stream browser page in the Extron folder. To connect the stream, from the browser, drag and drop the stream anywhere on the Player Controls panel (see Player Controls on page 16).

RTSP Multicast (Pull Streaming)

If an SME 100 is configured for RTSP multicast, the SMD 101 must still connect to it using the SME 100 IP address (for example rtsp://192.168.254.100/extron) 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)

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.
