Know How of DVI Extender, DMI Extender, VGA Extender

DVI Extender is a device which is used to transfer high resolution video signals to the DVI (Digital Video Interface) display devices located at remote sites. It can be directly connected to the computer system. Thus the signal transmission is possible through remote access also. The various types of DVR Extenders transmit the signal either through a Cat5/6/e or through fiber optic. It consists of a transmitter part which is always connected to the computer and the receiver part which is always located near the display device. It is used to help in in maintaining longer distance transmission. DVI extender has been found more in demand in the world of home entertainment as its biggest advantage of being connected between the PC and monitor.

DMI Extender transfers high-definition video signals via a sender and a receiver connected at the display end. The media of transmission is either a CAT cable or a fiber optic cable and receiver. The biggest advantage of using it is that the distance of the receiver from the transmitter does not matter at all. This device has the capability to transmit the high definition signals over long distances without any distortion. It delivers more noise free signal. The biggest advantage of HDMI extender over other ones is that the high quality video signal without any distortion can be transmitted. It is compatible with DVD players, set-top boxes and TVs. With the use of HDMI port located in this device.

VGA (Video Graphics Array) extender consists of a transmitter unit which is connected to the computer and receiver unit which is connected to the remote. The signal from the computer monitor is in digital format. It is used to convert the the signal from the computer into analog and for transmitting it the graphics card is left behind. It is later again converted to digital format at the other computer end. It somehow while transmission of the pixel resolution of the original signal. Here the connection is developed not through any software configuration but plug-in and plug-out technique is used. It is highly in demand in big educational institutes, offices and also at home. Basically video signals are between the host and the end target destination devices. The extenders will always prove to be the best in use to the common man and each one has its own advantages. These can find their use in military, industrial, commercial, aerospace applications. They can be used in displaying the output over a larger are be it in the airport or other such purposes.

DVI Extender - Video Signal Extension Over Fiber Optic Cables

The DVI Extender is a hardware device that can be used with inexpensive Cat5 / Cat6 UTP cable, and transmits digital video signals up to 100 meters. This device, when used with fiber optic cable transmits the signals to greater distances. It consists of two units, a local transmitter placed next to the DVI source and a remote receiver placed next to the remote LCD monitor. The transmission is done while retaining perfectly clear and crisp video quality. These extenders are also available in 2, 4, and 8 port versions referred to as DVI Splitter Extender units. This unit allows you connect your local PC and also the local DVI monitor next to it, while the receiver units allow you to connect to each of the remote DVI monitors. This extension device is extensively used in applications where the same image needs to be displayed on multiple remote locations. The DVI Fiber Optic Extender and DVI Dual Link Fiber Optic Extender are the different categories of these extenders devices available on the market.

DVI Fiber optic extender uses fiber optic cable to transmit high resolution digital video over long distances. The advantage of using these extenders is that you eliminate the need for long and bulky fiber cables with DVI connectors. These units don't need any additional equipment to boost the video signal. The Extender units are fully compatible with DVI for video transmissions to gas-plasma, liquid-crystal, light-emitting-diode displays and digital projectors. There is no need for initializing the software; different displays can be plugged or unplugged; and it protects data transmission from EMI and RFI. The extender is generally used in home movie theater, aerospace, medical industry, hospital industry, military / government applications and conference centers.

Since a DVI Extender allows the transmission of digital video signal over long distances it eliminates the use of bulky cables. Another advantage is that it overcomes the distance restrictions which are associated with DVI cables. These units are CE, FCC and RoHS compliant. Some versions of these devices are available with audio receivers and used for multi media broadcasting thereby causing an increase in its demand.
