Unicast Streaming Method — An Overview
This streaming method is used for on‑demand video with low latency and uses a variety
of streaming protocols. It can be used where the network infrastructure does not support
multicast traffic. Typically, unicast streaming is used for a point‑to‑point (one‑to‑one)
connection (SMP 300 Series to single viewing device), but can be configured to use multiple
active connections.
Unicast streaming can use push or pull streaming. It can push the data to individual or
multiple viewing devices, or it can use pull steaming, where the SMP 300 Series waits for an
individual viewing device to request the stream before broadcasting.

NOTES:
• When unicast streaming, the SMP 300 Series sends an individual stream to each
viewing device. This means that the total bandwidth increases as the number of
actively connected viewing devices increases and the total bandwidth decreases as
the number of actively connected viewing devices decreases.
In the figure above, n represents an unspecified number of additional streams.
