Audio video cables provide 2 primary channels, including analog audio connecting the VCR, CD player, and DVD player at your home. More than a decade has passed since people have stopped talking about cables. In reality, cables are still used everywhere. If you want to stream your games and videos from your computer in real time, or check your security cameras, then there you need this. But, to use them properly, the first thing is to know these cables in detail. Also, you must ensure that you will sometimes need an adapter to connect the hardware to the other. So keep reading further to explore each type of cable, and see for yourself whether your electrical appliance needs an adapter or not.
1. What is RCA?
RCA cables are tri-colored plugs that extend to connect 3 jacks on the TVs or a projector. These cables carry audio and video signals from the component device to an output device. If you were ever hooked to a CD player, DVD player, or old TV as a kid, you would have seen these cables.
There are mainly 2 types of cables, which includes a composite video and components. The colors used in these plugs are mainly red, yellow, and white to distinguish them from other cables.
A composite video is a non-digital analog that helps carry all the data required for video in one signal. This is possible as three different signals combine to form an analog video. This includes squeezing the data into one signal, reducing the data’s quality. Therefore, you cannot be very sure of the quality, as it is always compromised. Composite video is not in use these days, to design high-definition analog, or digital video signals; it is not possible.
Pros:
Many gadgets, from televisions to digital cameras require this cable. These are very flexible and easy to handle. These are also cost-effective, and the color association is easy to remember. Once familiar with color association, it becomes easy to use and connect properly.
Cons:
The main disadvantage of these cables is that not everyone remembers the color-coded wires. Also, it becomes difficult to handle 3 different wires for a single electrical appliance. This cable does not provide high-quality video.
2. What are S Video Cables?
S-video is also called separate video cables, or Y/C which is a signaling standard. These are special cables that carry the audio transmission. This type of cable encodes video signals with two primary channels. The first one shows the intensity of the video denoted by ”Y,” and “C” shows the chrominance. There are many types of S-video cables available in the market. So, based on the requirement of the electrical appliance, you can choose the one you require.
Pros:
Major benefit of using S video cables is that it is easy to maintain luminance and chrominance. It helps separate the signals that do not need a low pass filter luminance to get a composite video superior color palette. Thus, it does not require a low pass filtering and blurring in the whole process.
Cons:
Carrying color information is just one signal, so each color has a specific encoding that varies from one local standard. Also, it has a limited color palette, so there can be a little color variation while transmitting.
3. What are HDMI cables?
HDMI stands for “High Definition Media Interface.” It is not a single cable, but a technological standard design. HDMI helps transmit high definition and high-resolution audio and video signals. It is one of the best ones among the ones listed above. HDMI helps transmit uncompressed signals, making them high resolution, in the same way as it was initially transmitted Also, you can transmit audio and video with just one cable. It is also used in many electrical appliances like HDTVs, projectors, and other media players.
Pros:
It is a two-way communication cable to play live streams and online games. The major advantage is that it transmits high-quality video and images. It also helps view the videos in 1080P and 4K. Also, it is a high speed and does not require any other cables as it is self-sufficient. Also, it is mostly used in modern electrical appliances, as it is easy to use and maintain.
Cons:
One major con about HDMI cables is that these are expensive and sometimes may delay the output, causing more blank screens and errors. To transmit the data over a long distance.
Conclusion:
So, if you are wondering which one of these cables is a better fit for you, then let me tell you one thing; it depends on your needs and for what electrical appliance you need it for. No one cable fits all and every kind of electrical appliance. RCA cables cannot help you with better resolution. Or a HDMI cable cannot help you with blank screens while transmitting to a longer distance. In most cases, RCA cables will work best for your old consoles, and for your old TVs, S video cables will work best, as they do not have an HDMI port to help improve the picture quality. To use these cables, you need to have an RCA adapter, or a S video adapter that allows you to connect one hardware to another without losing its function. So, you must take all the required cables and adapters carefully for an electrical appliance at your home.
