Multicast IP Addressing for Multiple SMP300 Series Installations
Pull streaming (RTSP)
When multiple SMP300 Series devices are installed in a system and multicast addressing is
used for push or pull streaming, please follow the guidelines below for configuration.
NOTE: To prevent conflicts, always check to see if other devices using the same IP
address have already used a port number before using it in the SMP300 Series.
For most applications, the multicast address should use 239 as the first octet and should
be unique for each SMP 300 Series. The port number can remain at the default (12340) as
shown in the next table.
Device
SMPIP Multicast IP
Multicast Port
SMP1
192.168.254.10 239.199.188.138 12340
SMP2
192.168.254.11 239.199.188.139 12340
SMP3
192.168.254.12 239.199.188.140 12340
NOTE: The SMP300 Series automatically inserts the ending port number when the
initial port number is entered.
Push streaming (TS/UDP, TS/RTP, ES/RTP)
Push streams to a multicast address generally require only two ports, except for
ES/RTP which requires four. When push streaming from multiple SMP300 Series devices to
multicast addresses, the same IP address rules apply as with pull streaming.
For push streaming, the destination IP and port number are adjusted using the encoder
presets page.
Streaming Method Overview
The streaming method used by the SMP300 Series should be considered carefully.
Multicast is typically used for live multicasting a "one‑to‑many" session when it is known
there are multiple viewers of a stream. Unicast streaming is used for on‑demand video
where the network infrastructure does not support multicast traffic. Typically, unicast
streaming is used for a point‑to‑point (one‑to‑one) connection.
Protocols Used for Streaming
Streaming protocols must be selected based on the streaming method and the SMP300
Series capability. The following transport layer protocols can be used for SMP streaming.

The transport protocols are summarized in this section. For information on how to change
the SMP300 Series transport protocol, see Streaming on page36.
