The average person who doesn't work in IT probably has no idea what the different types of video cables are, let alone what they do or why you need them. You probably don't need to be an expert on these things either. Still, it can be good to have some working knowledge to buy the right video cable and avoid overspending on the equipment you don't need.
The first thing you need to know about video cables and wires is that there are many different types of cables. Understanding how they differ from one another can help you pick the right one for your needs. So, how many different types of video cables are there? Technically, the answer to that question depends on how you define a type of video cable. In reality, however, 26 different video cables are used by businesses, schools, government agencies, and consumers every day.
This article will take you through 26 of the most common types of video cables, their primary functions, and what equipment they typically connect to in layman's terms to become an expert on the subject yourself.
Two Primary Types of Video Cables
The first distinction you need to make when it comes to video cables is the difference between analog and digital cables. Analog cables transmit an analog signal, a continuous wave that can take on any value within a given range. Digital cables, on the other hand, transmit digital signals, which are a series of discrete pulses that can only take on a limited number of values.
The vast majority of video cables you'll encounter these days are digital cables, as the transition from analog to digital signals has been taking place for many years now. However, there are still a few analog cables in use, so it's important to know the difference.
Most people have moved on from analog video cables, but some die-hards still hold onto their VHS players and CRT TVs. If you're one of those people, you might be wondering what kind of cable you need to connect your devices. The answer is an analog video cable. Analog video cables are designed to carry an analog signal produced by most older devices.
These cables typically have three pins. They can be used to connect various devices, including VCRs, DVD players, and game consoles. If you're still using analog devices, an analog video cable is a perfect way to keep them connected.
There are a variety of digital video cables on the market, and it can be confusing to know which one you need. The most important thing to keep in mind is the resolution of your display. If you have an HD television, you'll need a cable carrying a high-definition signal. The most common type of high-definition cable is HDMI, which can take both video and audio signals.
If you have an older television, you may need a different type of cables, such as component video or S-video. It's also essential to ensure that the cable you choose is compatible with your equipment. For example, some cables can only be used with specific devices, such as Blu-ray players or video game consoles.
Different Types of Video Cables and Their Functions
Perhaps you need a new video cable, wondering which one is right for you. This section will take you through some of the most common types of video cables and their primary functions.
Apple Display Connector
The Apple Display Connector (ADC) is a proprietary connector used by Apple Inc. to connect their computers and displays. It was first introduced in 1998 with the release of the iMac G3, which was later used on the PowerBook G4, iBook G4, MacBook Pro, and Intel-based iMac and Mac mini. The ADC connector carries digital video and analog video signals, power, and USB data.
It was designed to simplify the process of connecting an external display to a Mac computer. However, the ADC connector is no longer used by Apple. They have switched to using HDMI or DisplayPort connectors instead. While the ADC connector is not used anymore, it can still be found on some older Apple displays.
MHL cables are used to connect certain types of electronic devices. Specifically, they connect devices with an MHL-enabled port to another device, such as a television or monitor. These cables are designed to provide both power and a high-definition signal, making them ideal for use with devices like smartphones and tablets.
Both devices must be compatible with the MHL standard to use an MHL cable. Additionally, the device with the MHL-enabled port must be connected to an external power source. Once these conditions are met, the user can simply connect the two devices using the MHL cable and begin enjoying high-definition content.
BNC cables are a type of coaxial cable. They're composed of an inner core surrounded by an insulating material and an outer shield. The outer shield protects the inner core from electromagnetic interference (EMI), which can cause problems with signal quality. BNC cables are commonly used in video and audio applications as they provide excellent signal clarity and low levels of EMI.
They're also relatively easy to install and use, making them popular for many home theater systems. However, BNC cables are generally more expensive than other coaxial cables. They can be challenging to work with if you don't have the proper tools. BNC cables are still an excellent option for high-quality audio and video connections.
SDI (Serial digital interface) is a type of interface that uses serial communication to transfer digital data. In other words, it sends the data one bit at a time over a single line. The advantage of using SDI is that it requires less bandwidth than the parallel digital interface, which sends multiple bits simultaneously over numerous lines.
As a result, serial digital interface is often used in applications with limited bandwidth, such as video and audio signals, and is relatively easy to implement. For these reasons, the serial digital interface has become the standard for many digital devices.

Different Parts of a Video Cable
We've looked at some of the most common types of video cables; now, let's look at the different parts of a video cable.
Most video cables use some internal wiring to function correctly. This type of wiring is typically made from copper, a good conductor of electricity. The copper wires are arranged in a specific way inside the cable. This helps to carry the electrical signal from one point to another. In some cases, the internal wiring may also be shielded, which helps to reduce interference from outside sources.
Experts recommend using oxygen-free copper wiring in video cables. This type of wiring is more expensive than regular copper wiring, but it provides a higher quality signal. By understanding how internal wiring works, you can ensure that your video cables will provide a clear and consistent signal.
In addition to the internal wiring, most video cables also have some external wiring. This type of wiring is typically made from aluminum, a good conductor of electricity. Aluminum is also very lightweight, making it ideal for use in video cable.
The external wiring is typically used to connect the cable to the devices it's meant to be used. In most cases, the external wiring will be color-coded to tell which wire goes where easily.
Video Cable Connectors
At the end of most video cables, you'll find some sort of connector. This allows you to connect the cable to the devices you want to use. The most common connector type is the RCA connector, typically used with composite video cables. Other connectors include BNC connectors, DIN connectors, and HDMI connectors.
When choosing a video cable, it's essential to ensure that the connector is compatible with the devices you want to use it. Otherwise, you won't be able to connect the cable properly.
Many video cables are shielded to protect the signal from interference. The most common type of shielding is conductive shielding, which helps to reduce electromagnetic interference. This type of shielding typically uses a copper braid or foil surrounding the internal wiring.
Other types of shielding include dielectric shielding and magnetic shielding. Dielectric shielding helps to reduce radio frequency interference, while magnetic shielding helps to reduce inductive interference.
The jacket is the outermost layer of the cable, and it's typically made from PVC. The jacket protects the internal parts of the cable from damage, and it also makes the cable easier to handle. In some cases, the jacket may also be color-coded so that you can easily identify the type of cable.
Video Cable Buying Guide

It's highly recommended to use oxygen-free copper wiring for the best results. Also, be sure to check the type of jacket that's used. The jacket should be made from a durable material that can protect the internal parts of the cable.
The length of the video cable is also an important factor to consider. In general, the longer the cable, the more expensive it will be. However, you'll need to make sure that the length of the cable is appropriate for your needs. For example, if you're only going to use the cable to connect a DVD player to a TV, you won't need a very long cable. On the other hand, if you're going to use the cable to connect a computer to a projector, you'll need a longer cable.
As we saw earlier, the connector type is also an essential factor to consider. Be sure to check the type of connector used on the devices you want to use the cable with. Otherwise, you won't be able to connect the two devices properly.
The pixel resolution is the number of pixels displayed on a screen. The higher the pixel resolution, the better the quality of the image. When choosing a video cable, be sure to check the maximum pixel resolution that it can support.
The frequency response is the range of frequencies that an audio cable can reproduce. The higher the frequency response, the better the quality of the audio. When choosing a video cable, be sure to check the frequency response to be sure that it can reproduce the audio frequencies you need.
The cable gauge is the thickness of the wire—the thicker the wire, the better the signal quality. When choosing a video cable, check the cable gauge to ensure it's thick enough to carry the signal you need.
Of course, price is also an important factor to consider. Video cables can range from a few dollars to a few hundred dollars. In general, the more expensive cables will offer better performance. However, you'll need to decide how much you're willing to spend on a video cable.
