What do You need to Know about Video Adapters and Connectors to Make a Fantastic Purchase?
If you are one of those people who leaves no stone unturned until you are able to enjoy a realistic and spectacular viewing experience using available video gear and products, then you should want to know more about video adapters. A video adapter is essentially a device that you can plug into you a source of video, say a computer with a display device attached to it, to allow it to display photographs and videos.
Some video adapters and connectors are powerful enough to even convert a particular type of video signal to another format altogether to suit the specifications of the specific display device attached to the video source. The quality of a video adapter and connector determines the quality of signals that your display device receives and consequently, the viewing experience that you can enjoy. So it is crucial that you carefully select a video adapter and connector that match the specifications of your video gear.
Different Types of Video Adapters and Connectors
Trying to find out a video adapter and connector that best fits your needs may prove to be a difficult task considering that there are many different types of these devices. However, knowing the various important features of these types will help you make the right choice for your video gear.
BNC Adapters and Connectors
BNC connectors and adapters are available in various types—BNC to BNC adapters and connectors, BNC to F adapters and connectors, and BNC to RCA adapters and connectors.
BNC connectors are small-sized and lightweight RF connectors that can be quickly and easily installed and removed. These are usually made to support 50 ohms and 75 ohms and are compatible with cables with similar characteristic impedance. These two versions of connectors have slightly different dimensions but they can still be used in conjunction without compatibility issues. The 50 ohm connector can support frequencies of up to 11 GHz while the 75-ohm version can support up to 2 GHz. In this context, it is worth mentioning that the 75-ohm BNC connectors are designed to suit impedance-matched cable connections used in high-performance scenarios such as broadcast situations and CATV applications.
BNC connectors contain two bayonet lugs on the female side of the device. So while buying these connectors, you should ensure that these are structurally sound and can provide a secure connection. These connectors are available in a variety of termination styles like clamp/solder, crimp/crimp, and field serviceable versions. You should also thoroughly check these contact points before buying a connector so that you are assured of the highest degree of efficiency during transmission of signals.
The efficiency of data transmission also depends on the metal with which the connector is made. Metals such as gold and nickel are highly conductive and ensure speedy and lossless transmission of signals. So some of the best and the most effective BNC connectors in the market are either nickel- or gold-plated. This coating additionally acts as a layer of shielding that prevents interference from electromagnetic and radio frequency waves generated by other electronic appliances in the vicinity and preserves signal integrity.
F to F Adapters and Connectors
These connectors works with various different types of coaxial cables thereby providing you with greater flexibility to use your video gear the way you want to without needing to shell out a fortune for costly upgrades. The highest quality of F to F adapters and connectors are gold plated and thus provide superior conductivity. For fantastic structural integrity, you can also choose models that have a ridge or a band on them.
RCA to F and F to RCA Adapters and Connectors
The RCA to F and the F to RCA adapters and connectors enable you to change an RCA-type connection to an F one or vice versa without needing to buy and clutter your living or workspace with a plethora of new cables. While buying such adapters and connectors, make sure that you get yourself a durable model that will last long and also has adequate shielding to protect the video signal from outside noises.
S-Video to RCA and RCA to S-Video Adapters and Connectors
An S-video to RCA adapter changes an S-video signal to a composite video channel. An S-video signal carries the brightness and color information of the video separately. Using an S-video to RCA adapter combines these two pieces of video information into a single signal. The loss of quality that accompanies this data integration is hardly discernible to the naked eye. However, in this context, it is worth mentioning that if the loss of signal quality is of particular concern to you, you can additionally buy adapter cables that will convert the S-video input but channel the output into two RCA connectors. One connector will transmit the brightness data while the other, the color data. This will preserve the quality of the original signal.
S-video to RCA adapters are available in many different configurations. The most common types are the female-female adapters and the barrel connectors. The former allows you connect an S-video and a RCA cable while the latter is handy to wield. You might need to use such an adapter when your source of video is a camcorder but the display device is a television set that can support only composite signals.
The RCA to S-video adapter lets you convert a composite video signal into an S-video one. In this case, the RCA video signal gets divided and the brightness and color data contained in it is separated and transmitted. You may need to use this adapter if you want to connect a VCR that generates RCA video output to a television that supports only S-video signals. An RCA to S-video is easy to install and allows you to enjoy a superior viewing experience on an S-video system without needing to walk down the street towards costly upgrades.
Now that you know about the various types of video adapters and connectors, you can buy one that meets the specifications of your video system. Just make sure that you thoroughly inspect the physical characteristics of the model you buy so that the device lasts longer and provides a solid and powerful signal conversion and transmission.
