When it comes to modern televisions, there are a plethora of acronyms and terms that may be unfamiliar to the average consumer. One such term that may be encountered is “AV,” which stands for “Audio Video.”
Understanding the Importance of Audio and Video
Audio and video are two of the most important elements of any television experience. The audio is responsible for delivering the sound that accompanies the visuals on the screen, while the video is responsible for displaying the images and moving pictures. Together, these two elements create the immersive and engaging experience that we have come to expect from our televisions.
The Role of AV in Modern Televisions
In modern televisions, AV typically refers to the inputs and outputs that are used to connect external devices such as DVD players, gaming consoles, and cable boxes. These inputs and outputs are typically located on the back or side of the television and are used to transmit the audio and video signals from the external device to the television.
The most common AV input is the composite video input, which uses a yellow RCA connector to transmit the video signal and white and red RCA connectors to transmit the left and right audio channels, respectively. Another common AV input is the HDMI input, which uses a single cable to transmit both audio and video signals in high definition.
Advanced AV Features
In addition to the basic AV inputs and outputs, many modern televisions also come equipped with advanced AV features. Some of the most common of these features include:
HDMI-CEC: This feature allows external devices to be controlled directly from the television remote, eliminating the need for multiple remotes.
ARC (Audio Return Channel): This feature allows audio to be sent from the television to an external sound system, such as a home theater system, without the need for a separate audio cable.
Deep Color: This feature allows for a wider color range, resulting in more vibrant and accurate colors on the screen.
3D: This feature allows for the display of 3D content, creating a more immersive viewing experience.
AV vs HDMI
While AV and HDMI inputs and outputs may seem similar, there are some key differences between the two. HDMI, or High-Definition Multimedia Interface, is a newer technology that offers a number of advantages over AV. Some of the main advantages of HDMI include:
Higher resolution: HDMI supports resolutions up to 4K, while AV is typically limited to 1080p.
Better audio: HDMI supports a wide range of audio formats, including Dolby Atmos and DTS:X, while AV is typically limited to stereo audio.
Single cable: HDMI uses a single cable to transmit both audio and video signals, while AV requires separate cables for audio and video.
Choosing the Right AV Inputs and Outputs
When choosing a television, it is important to consider the AV inputs and outputs that are available. For those who plan to connect a wide range of external devices, multiple HDMI inputs and outputs may be preferred. For those who primarily plan to connect a cable box or streaming device, a single HDMI input may be sufficient. Additionally, if you’re planning on having a home theater system, it’s important to make sure that your TV has an audio return channel (ARC) feature.

Can I use AV and HDMI inputs and outputs at the same time?
Yes, many modern televisions have both AV and HDMI inputs and outputs, so you can use both at the same time.
Can I connect a home theater system to my TV using AV?
It depends on the specific home theater system and TV model. Some TVs have an audio return channel (ARC) feature, which allows audio to be sent from the television to an external sound system, such as a home theater system, without the need for a separate audio cable.
Are there any disadvantages to using AV inputs and outputs?
AV inputs and outputs are typically limited to 1080p resolution and stereo audio, compared to HDMI inputs and outputs that can support 4K resolution and a wide range of audio formats. Additionally, AV inputs and outputs require separate cables for audio and video, whereas HDMI uses a single cable for both.
