Commonly used video equipment including video splitter, video extenders, video matrix switcher , multi-screen video signal processors, video signal converter that several major equipment.
Video distributor, is mainly used to copy the source video output signal into multiple outputs ; major application type is a sub- sub 4,1 8,1 3,1 16 four specifications . RCA and BNC interfaces form is divided into two kinds.
Video Signal Extender is mainly used for video signal attenuation additions, indoor video signal transmission distance up to 100 meters, the need to configure signal amplifier, over 100 meters using signal extender ;
Video Matrix Switcher , mainly used for multi-channel video signal input and output channel switching , lcd module to achieve a number of entry for more options . Divided into RCA and BNC interfaces.
Multi-screen video signal processor , mainly for multi-channel input signal displayed on the screen at one occasion , common specifications for the 4-screen , six screens , 9 screens , 13 screens , 16 screens five formats .
Video signal converter main function is to convert the video signal output VGA signal into a computer .
Computer signal processing equipment mainly includes VGA signal splitter, VGA Extender , VGA matrix switcher or RGB matrix switcher.
VGA signal splitter is used to copy the output port of a computer into multiple VGA output , common specifications for 1 min 2,1 4,1 8,1 16 minutes of four.
VGA signal extenders, mainly for long distance transmission of computer signals with twisted pair and fiber optic transmission in two ways, using twisted pair within 200 meters and 200 meters above must be using optical fiber transmission.
VGA or RGB matrix switcher for computer signals are multiplexed input and output channel selection, an entry into the right for more or more , which could be exchanged . VGA Matrix Switcher VGA interface common to use a computer , RGB matrix switcher is a computer signal into red, green , blue, line frequency , field frequency of five independent channels , the transmission signal stability , distance farther than VGA , commonly 5BNC interface.
Multi-screen display controllers :
Mainly used for video , computer , network signal mixed display . Remote network access management , image display , it can display the entire screen , window display roaming , single-screen multi-screen display .
Multi-screen controller can access up to 32 channels of video input ( plus expansion chassis can access even more ) , OLED Display the conventional 4-way VGA input, 2-way network input and output cables you can use VGA or DVI, and the number of output channels same number of screens .
With DLP rear projection , PDP plasma wall with mosaic DID LCD splicing increasingly intense competition , the advantages of large-screen LCD is gradually being recognized more industries and areas , as most of the customer's choice .
