1.1.4 Video Module
The Video Module is an autonomous video capture and broadcast device. It has one (1) input port for
capturing images from a dedicated buffered output port of the primary radar. The module digitizes the
video signals and outputs the video data through an Ethernet port. Video modules with up to four (4)
inputs are also available for capturing images from additional video displays.
The module provides periodic updates of RGB images. For maximum flexibility, the board holds sufficient
memory to accommodate 1600 x 1200 x 24-bit colour images and refresh rates up to 85Hz. For
maximum capability, the A/D samples at up to 170MHz, with a clock inversion option that allows larger
images to be sampled by interleaving two (2) consecutive frames.
The Data Management Module (DMM) initiates the capture of video information and specifies its
configuration. This includes:
The video channel to be digitized.
The sources of the vertical and horizontal syncs.
The coefficients for the PLL-generated pixel clock (or selection of an external clock).
The dimensions (number of samples and lines) of the captured frame.
