1. Product Overview

    HV-FH41 HD quad video multiplexer is a high-performance image processor,and it's main function is turn 4 BNC、VGA、HDMI input signal into 1 HD HDMI and VGA signal,which make 4 digital signal display in oneHD screen unit synchronously and HDMI signal with USB(like mouse、keyboard) can be switched synchronously. HV-FH41 HD video multiplexers support various kinds display unit with HDMI,such as:projector、LCD、DLP、plasma、full color LED.
HV-FH41 HD video multiplexers is chief applied to video conference、teaching、display and demonstration、stock ect, where need single display unit display multi HD signal synchronously, and it generally used in the market at present.

    Meanwhile,HV-FH41 video multiplexers is the only product that add USB synchronous switch,so when case or IRcontroller switch to fully display one signal ,correspondingly,USB of computer host also synchronous switch.It meet the demand of video conference which need swith mouse and keyboard synchronously.

 

2. Main Function

• 2.1. Support single display unit display 4 HD or analog signal synchronously;
• 2.2. Support 4 composite video、4VGA、4 HDMI, 12 input signal in total;
• 2.3. Support 1 VGA and 1HDMI synchronic output;
• 2.4. 4 USB signal Input,2 USB output,and USB connect mouse and keyboard or other device;
• 2.5. Support KVM function, that is USB、mouse、keyboard with video synchronous switch;
• 2.6. Compatibility all kinds of input resolution and support output ultrahigh resolution of 1920*1080;
• 2.7. Size and position of image can be adjust arbitrarily,and other functions,such as:windowing、superposition、roaming、PIP、POP.
• 2.8. Support regulatory image transparency, therefore you can see base picture though upper image;
• 2.9. It can be commonly used in any nation in the the world due to support ultra wide input alternating voltage of 100V to 240V ;
• 2.10. It's drawbench case is standard dimension of 19 inch and 1U height ,so it can be put on normal equipment cabinet;
• 2.11. It can be controled by case key、IR、RS-232 serial port and center control.
• 2.12. High quality HD quad video multiplexers is especially customized generate for video engineering;
•  

3. More detail about HV-FH41

3.1. Pure hardware construction

    Adopt pure hardware construction ,without CPU and memory,so booting only need 3 to 5 minutes,system stability,without crash,virus and system breakdown;can uninterrupted work for 24 hours a day of 365 days a year .

3.2. FPGA image process

    Adopt FPGA that is the most powerful image chip process technology at present.FPGA support various world's leading image processing technology,for example:DCDI edge smooth、ACM color automatically adapt、CSS light crosstalk suppression、SHARPNESS enhancement、dynamic contrast ratio enhancement、the real six axis color overlap、eliminate the noise amplification ect.
    In addition,possess many advanced function like 3D comb filter video decoding function,3D noise reduction and automatic adapt moving compensation's remove isolation technology,skin color adjust,enhance color brightness,GAMMA adjust and frame frequency switch ect.Which make output image texture smooth and sharp、clear and fluent、bright color without sawtooth and trailing .

3.3. Powerful operation capability

   Data use parallel processing,output port occupy one channel and data bandwidth reach 10.2G/S of each channel .So It can fully achieve high resolution of 1920*1080 display.High speed dynamic image without trailing、delayed、tear、frame loss、image catch up phenomenon.

3.4. Support input and output 1920*1080 HD signal

   HV-FH41 HD video multiplexers support 4BNC、4VGA、4HDMI, in total 12 input signal and HD video support interlaced and line-by-line input.It support highest input ultrahigh resolution of 1920*1080 and downward compatibility all kinds of resolutions; The highest output resolution support 1920*1080 after all input signal go though professional image processing chips and line-by-line export HDMI signal of 60HZ and it also can customize output resolution according to user demand.

3.5. USB switch

   HV-FH41 video multiplexers is the only product that built-in USB switch in the market,which perfectly solute the question that previous product can't synchronous switch video with USB connecting device(like USB mouse、keyboard).It will be widely used in various kinds video conference situation , will more convenient、more efficient、save more display equipment and operating space for user.

3.6. Regulatory Transparency

   Support PIP,so you can regulatory transparency for upper pitcture, therefore you can see base picture though upper image

 

4. controller

4.1. software control

   HV-FH41 HD video multiplexers contain green control visual interface HV sofeware.exe,available when starting up ,can achieve global function like switch input signal、Size and position of image adjust arbitrarily by using the mouse、save or invoke shortcut、fastly switch after custom 16 shortcut ect.

4.2. IR control

IR control can invoke 10shortcut mode without staring up computer;
Through IR can choose input signal of each channel,and adjust output resolution.

4.3. Case key control

There have 14 shortcut keys in the front panel,can realize 10 shortcut switch which are correspondent with IR control ,and mouse、keyboard switch alone.

4.4. Center control

HV-FH41 adopt frequently-used control code,user using center control after write control code into center processor accordding to demand;

5. Commonly display mode

  Our product solidify some frequently-used switch and display mode in order to make client more easier use it,and user can custom some common use pattern according to different individuate demand ,following are some common and practical mode:

5.1. Division display

  4 HDMI or VGA image signal display in one screen unit in quartering at the same time,can simultaneously monitor 4 HD HDMI or VGA signal ,as following:

5.2. Fully display one signal

  It can switch to fully display whichever input signal like HDMI、VGA and BNC though switching control.As following:

5.3. USB switch under quartering mode

  It realize mouse、keyboard KVM division function though control software or UA1、UA2、UA3 and UA4 keys, that is can control and operate whichever host under quartering mode by means of a set of mouse and keyboard.

5.4. Full screen and USB synchronous switch

  When you choose fully display certain HDMI or VGA,USB video signal also switch to this image signal which binding with it,so you can operate the host binding with fully display image through USB mouse、keyboard；

5.5.  Other mode

  By control software,it can achieve other multi individual display mode,like PIP、POP、window overlap、roaming、any size, any position.
