Sony's visual communication products (PCS series) encrypt video and audio data. Encryption provides secure connections and protects data from unexpected modification by hackers or other outsiders.
Sony uses two types of encryption technologies. One is an ITU-T standard-based format. This format allows Sony products, as well as other manufacturer's products, to communicate with each other, provided they support ITU-T encryption.
The other format is a Sony proprietary encryption standard, which is supported only over IP connections. A common password is required for all attendees to participate in the same conference, which creates a more secure connection. Sony's visual communication products provide the encryption formats as standard functions, rather than as options.
