Internal Components
CPU / Operating System
System control is achieved by a single board computer (SBC) running an embedded version of
Windows XP with RTX real time extension.
PCI Bus
A standard high-speed PCI bus provides interconnection between all cards. This primarily carries
control data, plus local/network source data.
RAPT Image Bus
RAPT (Real-time Asymmetric Packetized Transfer) is a high-speed data bus used exclusively for the
transfer of video and RGB Graphics (VN-GLIMPSE) source data between Input and Output Cards.
Unlike PCI technology, RAPT is guaranteed to deliver data in real-time and to remain operational
even in the unlikely event of an operating system crash, allowing crucial source content to be
maintained on the target display.
