Calibre UK announce the availability of the SRC3100, which is said to be able to convert video in X, Y, Z stroke-written format to RS170 raster video in real time. It is also said to be capable of simultaneously processing both stroke symbology and stroke-written raster image data to generate a composite video image which can be recorded and replayed through conventional video equipment.
SRC3100 is thought to be ideal for recording and displaying cockpit or pilot displays for training and simulation purposes so that an instructor may analyse the performance and then replay the action to the trainee.
SRC3100 receives X-deflection, Y-deflection and Z-video intensity (raster video signal or bright-up signal) and the raster/stroke signal from the host system. It then monitors the raster/stroke signal to control whether the Z-video is used as bright-up or raster video so building a composite image from the two, as would be seen on a pilot's HUD (head-up display).
The input video from the selected source is digitised and its position within the SRC3100 frame buffer memory and hence on the output image is determined by the amplitudes of the X and Y deflection signals. These are sampled at ten-bit accuracy to ensure that input resolution is preserved.
A combination of proprietary analogue and digital signal processing or filtering techniques is used to eliminate noise on the input signals and to prevent aliasing and other potential image artefacts. Multiple frame buffers are used to permit input and output frame rates to be completely independent. Data are converted back into analogue RS170 format and two independent outputs are provided to allow simultaneous display and recording.
