SCN, a member of Barco's family of networked visualization products, provides lossless compres-
sion and transport of computer graphics over standard networks. It is especially suited for distributed visualiza-
tion of secure and/or legacy applications over IP networks.
With T

ORM
SCN, any computer graphics source can be captured and transported over an IP network without
the need for extra software on the source computer (host PC). This allows better security and requires less pro-
cessing power than software screen scraping tools.
