Multiple SME 100 Devices Using Multicast Streaming
When there are more than one SME 100 devices attempting to multicast, they must
use unique multicast IP addresses or port numbers (see "
Multicast IP Addressing for
Multiple SME 100 Installations " on page 169 for additional information).
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 (SME 100 to single viewing device), but can be configured to use multiple active
connections. See the tables in "
Streaming Capabilities and System Scalability " on
page 164 for information about the number of streams available.
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 SME 100 waits for an
individual viewing device to request the stream before broadcasting.

NOTES:
• When unicast streaming, the SME 100 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.
