System Specification for Video Frame Buffer
Version:1.0
24 January 2015
The unit is to be designed to capture video (video meaning image) input from a personal computer, buffer the captured video images in internal SDRAM and replay the captured video images to up to 48 individual VGA monitors in turn. The unit will be designed to meet the following requirements: -
1. The unit is to be designed such that the user can input up to a maximum of 48 images of a resolution of 800x600 (standard) up to a maximum of 1920x1080 (configurable). Each individual image to be captured is to be transmitted to the unit via a standard 19 pin HDMI or a VGA interface. The user presses a capture button on the unit when the user wishes the unit to capture a given image, the unit then captures the image and stores it in a SDRAM buffer. Each captured image is then displayed on one of up to 48 VGA monitors (in turn). The monitors will support VGA input at 800x600 75 frames per second.
2. Rather than one PCB handling all 48 images, the unit will be made up of multiple PCBs, each one of which can handle 6 inputs and can be linked/chained together up to a maximum of 8 PCBs (48 images) – when linked together the boards should maintain as thin a profile with possible - when components are added
3. The VGA connections from the unit to the individual monitors will consist of a flying lead connection from the circuit boards to a remote VGA plug.
4. Using a set of configuration switches on the unit the user can configure the number of individual images to be captured to the buffer and the number of VGA monitor connected.
5. Using a set of configuration switches on the unit or the individual PCBs the user can configure the resolution of images to be captured/screen resolution.
6. The unit will be designed to run from a standard 12Volt "WallWart" type mains adaptor.
7. The unit will be designed to meet all relevant UK electromagnetic emissions and susceptibility requirements as per :-

• The capture unit printed circuit boards will have suitable mounting holes to allow mounting in an ABS plastic enclosure.
• The capture unit printed circuit boards will have suitable connections to allow PCBs to be linked to each other.
