The output processing on SoundStructure that is available for these output channels is shown in the

following figure. All signals have the same processing that includes dynamics, parametric equalization,

Routing The Polycom Video Codec Signals

The Polycom Video Codec system receives the SoundStructure output signals and internal to the Video

Codec mixes the signals it needs to create the transmit signals to the Codec Voice Call interface and Codec

Video interface. These signals are mixed as follows:

The transmit signal to the remote video participants is mixed within the Polycom Video Codec to include:

● Codec Voice Call Mix Out

● Codec Stereo Mics Out

● Codec Line Mix Out

The transmit signal to the remote telephony (PSTN) Video Codec participants includes the remote video

participant audio and:

● Codec Voice Call Mix Out

● Codec Stereo Mics Out

● Codec Line Mix Out

This default routing inside the Polycom Video Codec means that the SoundStructure matrix does not have

to add these channels to the Codec Stereo Mics Out signal. Typically the SoundStructure matrix looks like

the following figure where the SoundStructure "Phone In" signal is routed to the "Codec Voice Call Mix Out"
