TV Wall Server 1 System Administrator’s Manual

System Requirement
The performance of TV Wall display quality is largely determined by the computer hardware
capability and number of live channels. The table below provides basic guidelines for
selecting proper hardware for TV Wall Server computer (1*) .
*1 These specifications are based on following camera settings:
1280x1024, 3Mbps, 18fps, MPEG-4
*2 In some cases, the dropping of frames on live view is done purposely to avoid system
instability caused by CPU overload. TV Wall Server program will automatically activate
“Decode I Frame Only” mechanism for all live channels when the server‘s CPU loading is
over 80%. The computer system at Standard level may occasionally switch to “Decode I
Frame Only ” mode, which provides fewer frames per second but still enough to tell
significant movements and original image resolution; while an Advanced-level computer
allows live channels to display at original video frame rate at all times due to its more
powerful CPU.
*3 The total concurrently displayed channels of all monitors. For example, a station of 6
monitors whose layout is using the arrangement below will have 1x 1 + 2x 9 + 3x 16
= total 67 live channels
1 monitor displaying 1x1 layout
2 monitors each displaying 3x3 layout
3 monitors each displaying 4x4 layout
*4 Please use 64-bit Windows operating system if your TV Wall Server computer has more
than 4GB RAM.
Microsoft Windows Operating System has limits on memory and address space,
regardless of the real or virtual memory available on a particular computer. Take Windows 7
