Encrypted6 Videoconference via LAN Chapter

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).

Note

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.
