4.1 Input cards
For showing information from external sources like video or RGB data on a Barco display wall a set of input cards
is provided. For integration of video the Q

display a signal will be called video window. The video windows can be scaled and moved within the proje jection

In general downscaling of the data is performed by the input card, upscaling is performed by the O

When displaying more than one video via graphic cards with analog output, the totally visible area of all videos
must be taken into account to calculate the frame rate. Due to transfer limits on the PCI bus other conditions
than mentioned in the table above apply for up-scaling of the videos.
