MULTISTREAMING
BRIC-Link II supports the ability to run one encoder per connec on, but this single encoder produces an audio
stream that may be sent to up to three des na ons simultaneously. This capability is referred to as a Mul stream ,
as the encoder creates a separate but iden cal outgoing stream to each decoder. With this increased workload,
a user’s internet connec on must be able to support these streams. For example, if an encoder runs at 35 kb/s
network u liza on, sending to two loca ons will require 70 kb/s upload speed from the network. Mul streaming
should not be confused with IP Mul cast, which is described in the next sec on.
Each BRIC-Link II can also only run one decoder , so it’s important that in a Mul stream environment, a maximum
of one stream is sent in the reverse direc on. This means that users interested in hearing a Mul stream must
turn o
ff their encoders. The diagram in Figure 70 shows a BRIC-Link II Mul stream arrangement. Codec A is the
Mul streamer, with Codecs B, C and D listening to the same audio. Codec B is set to return an audio stream back to
Codec A, but Codecs C and D are in receive-only mode.
In order to set up a Mul streaming scenario, a “Simplex” (i.e., one-way) Audio Pro fi le must be created using the
Pro fi le Manager Tab (as shown in Figure 71 ). The Transmit op on must be set to “O ff ” for either the Local or the
Remote encoder, depending on the speci fi c arrangement, as described below. The Simplex Pro fi le must then be
selected in the chosen Remote entry to ac vate receive-only mode.
