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 [0001] The invention relates to a multi-input video processing card. Background technique [0002] Multi-input video processing card is used to collect, process and output video data. Many existing industrial sites use multi-input video processing card to cooperate with the system for video monitoring, but the existing multi-input video processing The analog signal or a single digital signal needs to be processed at the same time in many occasions, so the system needs to be equipped with two processing cards, which is very complicated and increases the cost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, provide a multi-input video processing card, solve the defect that the existing multi-input video processing card cannot process analog signals and digital signals at the same time, and is very troublesome to use in many occasions . [0004] The obj...
