Codec
The LifeSize codec compresses outgoing video and audio content and data, transmits this
information to the far end of a call, and decompresses incoming information. You should not
need to interact with the codec once it has been properly installed in your environment.
Third Party Display
A third party display connected to the LifeSize codec enables you to access the user
interface and view video images during a video call. A second display may be connected to
the LifeSize codec if the system supports more than one display.
