Abstract
The invention discloses a multiple input video processing card. The card comprises a field programmable gate array (FPGA) chip and a video processor which is connected to the FPGA chip, wherein the FPGA chip is connected to a low voltage differential signaling (LVDS) converting red, green, blue (RGB) chip, an LVDS video input interface is arranged on the LVDS converting RGB chip, the video processor is connected to a video coder, an analog video input interface is arranged on the video coder, and the FPGA chip is connected to a video graphic array (VGA) output interface through a digital analog converter. The card can process analog signals and digital signals at the same time and outputs analog signals and digital signals to a monitor for display. The card has the advantages of being simple in structure and low in cost.
Description
Technical field
The present invention relates to a kind of many input videos transaction card.
Background technology
Many input videos transaction card, be used for video data is gathered, processes and exports, existing a lot of industry spot adopts many input videos transaction card coupled system to carry out video monitoring, but existing many input videos transaction card generally is merely able to process single analog signal or single digital signal, need simultaneously Analog signals and digital signal in a lot of occasions, system just needs two transaction cards of configuration like this, seems very numerous and diverse, but also has increased cost.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of many input videos transaction card is provided, solve existing many input videos transaction card simultaneously Analog signals and digital signal, use pretty troublesome defective in a lot of occasions.
Purpose of the present invention is achieved through the following technical solutions: many input videos transaction card, comprise fpga chip and the video processor that is connected on the fpga chip, be connected with LVDS on the described fpga chip and turn the RGB chip, described LVDS turns and is provided with the LVDS video input interface on the RGB chip, be connected with Video Decoder on the video processor, be provided with the analog video input interface on the described Video Decoder, fpga chip also is connected on the VGA output interface by digital to analog converter.
