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
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.
NOTE: The SMP 300 Series automatically inserts the ending port number when the
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.
Pull
Unicast
RTP (RTP over UDP)
The transport protocols are summarized in this section. For information on how to change
