The Camera Signal Splitter (CSSGL) may be used in several types of applications. In the most performance-demanding applications - the splitter gives enormous processing speed gain. Splitting of the camera video signal and triggering one of the grabbers only for even, and the other one for odd images - allows to achieve a doubled performance in terms of DPM. Even larger performance gain may be achieved using a cascade of splitters - where complicated and time-consuming tasks happen in numerous frame grabbers (image processing units) at the same time, in a pipeline fed through the CSS. Splitting camera signal may also be useful for a real time optical recognition and sorting tasks. The same video signal is processed and compressed by one frame grabber, transferred to host for archiving. The other, specialized frame grabber - analyzes only a certain small snippet of each document and makes an immediate sorting decision - depending on the snippet content.

Areas of Application:
In some applications the speed of processing is limited due to complicated algorithms for image processing. In other cases some parts of the image have to be processed with high priority to be able to take proper action, e.g. to recognize the OCR code on the payment document to have the ability to sort.
In those cases it is necessary to split the camera signal into two or more image processing units, to accelerate the processing.

Installation:
The Camera Signal Splitter (CCSGL) has one camera input interface and two camera output interfaces to image processing board.
Power supply of the CSS can be delivered in two different ways. One possibility is via a special power socket situated on the CSS, the other is from the IE64_HS board, in case the CSS is plugged on the board.

Technical Description:

• Power supply: 5V/DC 250mA through external socket
• Options: 3,3V/DC 250mA through IE64_HS extension board
• Input: single RJ-45 socket for high speed serial interface from camera
• Output: two RJ-45 sockets for high speed serial interface from camera
• Frequency Range: 40 - 75 MHz (960 to 1800 Mbit)
• Cascading: up to three levels (up to 8 image processing boards connected to the same camera signal)
