When confidentiality is required for a videoconference or 
a videoconference is held via the Internet, the Video 
Communication System enables transmission and 
reception of encrypted video, audio, and data. Conducting 
a videoconference using this feature is known as an 
encrypted videoconference via LAN.
This chapter describes how to conduct an encrypted 
videoconference via LAN.
The capability to conduct an encrypted videoconference 
via LAN is available only when using two PCS-TL33 
units, or when the remote party uses a Sony Video 
Communication System PCS-1/1P, PCS-11/11P, 
PCS-TL30, PCS-TL50, PCS-G50/G50P, or PCS-G70/
G70P, or when the remote party uses videoconferencing 
equipment from other manufacturers supporting H.235 
encryption.
The encryption feature can also be used in multipoint 
videoconference using LAN connection (including 
cascade connection via LAN).

In an encrypted conference only video signals, audio 
signals, and computer picture data are encrypted. Camera 
control signals (for controlling the remote party’s camera) 
will not be encrypted.
