Multistreaming - Comrex ACCESS MultiRack Product Manual

MULTISTREAMING

XV.
MultiRack supports the ability to run one encoder per instance, but this single encoder stream may be sent to up to
three destinations simultaneously. This capability is referred to as a Multistream, as the encoder creates a separate
but identical outgoing stream to each decoder. (Note: A User's Internet connection must be able to support these
streams.) For example, if an encoder runs at 35 kb/s network utilization, sending to two locations will require 70
kb/s upload speed from the network.
Multistreaming should not be confused with IP Multicast, which is described in the next section. Each MultiRack
can only run one decoder, so it's important that in a Multistream environment, a maximum of one stream is sent in
the reverse direction. This means that users interested in hearing a Multistream must turn off their encoders. This
can be a bit confusing because Multistream can be initiated from either end of the link.
FIgure 69 multIstreAmIng ArrAngement
Figure 69 shows a MultiRack Multistream arrangement. MultiRack A is the Multistreamer, with MultiRack B, C and
D listening to the same audio. In order to set up a Multistreaming scenario, the MultiRack encoders must be turned
Off. This is done by building a profile with either the Local or Return Transmitter mode set to Off, as shown in
Figure 70.
