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
F
SCN, any computer graphics source can be captured and transported over an IP network without
RANS
ORM
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.
T

SCN provides amongst others the following features:
RANS

•
external capture of the computer graphics output allowing complete host computing platform independency
•
graphic sources up to UXGA@60 Hz
•
active loop through with sync recovery for graphics data
•
DDC loop through
•
DDC generation, if graphics loop through is not used
•
hardware based encoding with optimal compression performance
•
distribution of graphics stream via unicast and multicast UDP
•
USB keyboard and mouse emulation
•
browser based configuration
Basic setup
A setup where the graphics output of the host PC is just captured and displayed is shown below. The graphical
output of the host PC is connected to T
operator will not be interfered and no software needs to be installed on the host PC.
T
F
SCN converts and compresses the graphical signal to a stream of graphical data and distributes it via
RANS
ORM
the LAN. This stream can be decoded by a wall controller of Barco which is equipped with a S
and be displayed on a display wall or other projection device.
T
F
SCN is controlled by a master PC via TCP/IP. Any PC in the same LAN can be used for this purpose.
