In the world of home entertainment, having a good understanding of the various input options on your TV can greatly enhance your viewing experience. One of the most common input options found on modern TVs is the AV input. But what exactly is AV input, and how does it work? In this article, we’ll delve into the world of AV inputs, exploring their history, functionality, and benefits.
A Brief History of AV Inputs
The term “AV” stands for Audio/Video, and AV inputs have been a staple of home entertainment systems for decades. The first AV inputs were introduced in the 1980s, with the advent of VHS players and video game consoles. These early AV inputs were typically in the form of RCA connectors, which consisted of three color-coded cables: yellow for composite video, white for left audio, and red for right audio.
Over the years, AV inputs have evolved to accommodate new technologies and devices. With the introduction of DVD players, component video inputs became common, offering improved video quality. The advent of high-definition TVs (HDTVs) and digital audio formats like Dolby Digital and DTS led to the development of HDMI (High-Definition Multimedia Interface) inputs, which have become the standard for modern home entertainment systems.
How AV Inputs Work
AV inputs allow you to connect external devices to your TV, such as DVD players, game consoles, and cable boxes. These devices send audio and video signals to the TV through the AV input, which are then processed and displayed on the screen.
There are several types of AV inputs found on modern TVs, including:
RCA Inputs
RCA inputs are the oldest type of AV input and are still found on some TVs today. They consist of three color-coded cables: yellow for composite video, white for left audio, and red for right audio. RCA inputs are typically used for connecting older devices like VHS players and DVD players.
Component Inputs
Component inputs are an improvement over RCA inputs, offering better video quality. They consist of three cables: green for Y (luminance), blue for Pb (blue color difference), and red for Pr (red color difference). Component inputs are typically used for connecting devices like DVD players and game consoles.
HDMI Inputs
HDMI inputs are the most common type of AV input found on modern TVs. They offer the best video and audio quality, supporting resolutions up to 4K and digital audio formats like Dolby Digital and DTS. HDMI inputs are typically used for connecting devices like Blu-ray players, game consoles, and cable boxes.

What is AV input on a TV?
AV input on a TV refers to the Audio/Video input ports that allow users to connect external devices such as DVD players, gaming consoles, and computers to the TV. These ports enable the transmission of audio and video signals from the external device to the TV, allowing users to watch movies, play games, or access content from other devices on their TV screen.
The AV input ports on a TV can vary depending on the model and brand, but common types include HDMI, composite, component, and VGA. Each type of port has its own unique characteristics and is designed to work with specific types of devices. Understanding the different types of AV input ports and how to use them can help users get the most out of their TV and enjoy a wider range of content.
How do I connect a device to the AV input on my TV?
To connect a device to the AV input on your TV, you will need to locate the AV input ports on the back or side of your TV. Identify the type of port that matches the output port on your device, such as HDMI or composite. Then, connect the corresponding cable to both the device and the TV. For example, if your device has an HDMI output, you would connect an HDMI cable to both the device and the TV’s HDMI input port.
Once you have connected the device to the TV, you will need to select the correct input source on your TV. This is usually done using the TV’s remote control and navigating to the input menu. Select the input source that corresponds to the port you used to connect the device, such as HDMI 1 or composite. Your TV should then display the content from the connected device.
What is the difference between HDMI and composite AV inputs?
HDMI (High-Definition Multimedia Interface) and composite are two different types of AV input ports found on TVs. HDMI is a digital connection that can transmit high-definition video and audio signals, while composite is an analog connection that can transmit standard-definition video and audio signals. HDMI is generally considered to be a higher-quality connection than composite, as it can transmit more detailed and clearer video and audio.
In terms of usage, HDMI is commonly used to connect devices such as Blu-ray players, gaming consoles, and computers to a TV, while composite is often used to connect older devices such as VHS players or DVD players. If you have a device that has both HDMI and composite outputs, it is generally recommended to use the HDMI output for the best possible picture and sound quality.
Can I use multiple AV inputs on my TV at the same time?
Yes, most modern TVs allow you to use multiple AV inputs at the same time. This means you can connect multiple devices to different AV input ports on your TV and switch between them using the TV’s input menu. For example, you could have a DVD player connected to the composite input, a gaming console connected to the HDMI 1 input, and a computer connected to the HDMI 2 input.
To switch between different AV inputs on your TV, you will typically need to use the TV’s remote control and navigate to the input menu. From there, you can select the input source that corresponds to the device you want to use. Some TVs may also have a button on the remote control that allows you to quickly switch between different input sources.
How do I troubleshoot AV input issues on my TV?
If you are experiencing issues with the AV input on your TV, such as a lack of picture or sound, there are several troubleshooting steps you can take. First, check that the device is properly connected to the TV and that the correct input source is selected. You should also check that the device is turned on and that the volume is not muted.
If you are still experiencing issues, try switching to a different AV input port on your TV or using a different cable to connect the device. You can also try resetting the TV to its default settings or consulting the user manual for troubleshooting guidance. If none of these steps resolve the issue, it may be worth contacting the TV manufacturer’s customer support for further assistance.
Can I use AV inputs to connect a computer to my TV?
Yes, you can use AV inputs to connect a computer to your TV. The type of AV input you will need to use will depend on the type of output ports on your computer. For example, if your computer has an HDMI output, you can connect it to the HDMI input on your TV using an HDMI cable. If your computer has a VGA output, you can connect it to the VGA input on your TV using a VGA cable.
Once you have connected your computer to your TV, you will need to select the correct input source on your TV. You may also need to adjust the display settings on your computer to ensure that the image is displayed correctly on the TV. Some computers may also require you to install additional software or drivers to enable the TV connection.
Are AV inputs on TVs becoming obsolete?
While some newer TVs may be starting to phase out certain types of AV inputs, such as composite or component, HDMI and other digital AV inputs are likely to remain a standard feature on TVs for the foreseeable future. In fact, many modern TVs are now incorporating multiple HDMI ports and other advanced AV inputs, such as USB and Ethernet ports.
That being said, the way we consume content is changing, and some users may be opting for wireless streaming devices or smart TVs that can access content directly from the internet. However, for users who still want to connect external devices to their TV, AV inputs will likely remain a necessary feature.
