AV cables, short for audio and video cables, are essential for connecting various devices such as DVD players, gaming consoles, decoders and home theatre systems to your television. These electric cables are more versatile and common than you might think, offering multiple types to suit different setups. Before making a purchase, it's important to understand how these wires work and the different types of AV cables available in the market.
How Do AV Cables Work?
AV cables are essential for connecting audiovisual devices and transmitting both video and audio signals. These cables come in different categories based on the number of sound channels, control signals and video channels they support. By using these cables, you can easily connect display sources to your TV, where the display unit or source decodes the signal, and the AV cable transmits it to your television.
AV cables are designed to transmit both video and audio signals, and the key to a great experience is connecting them correctly. Without audio and video cables, devices like Blu-ray players, DVDs, VCRs and other electronic devices wouldn't work properly.
A common AV cable features a single jack on one end for connecting to your display source, like a decoder, video game console, or sound system. The other end has three colour-coded jacks - white, black and red. These are meant to be connected to your television or AV plates. Each jack has its own specific function. For instance, the white jack is responsible for delivering video signals. For sound signals, such is the role of the red and yellow jack.
The best part is that connecting an audio-video cable is simple and doesn't require specialised knowledge. The cables are colour-coded, so all you need to do is match each colour to its corresponding port on your TV. Even if you're using an AV adapter, make sure to connect the white, red, and yellow jacks to the correct ports for the best signal quality.
Different Types of AV Cables
HDMI
High-Definition Multimedia Interface (HDMI) cables transmit uncompressed digital audio and video signals, supporting high-definition resolutions and multi-channel audio. HDMI displayport cables are commonly used to connect devices like Blu-ray players, gaming consoles, and TVs.
RCA
RCA cables, also known as composite cables, consist of three colour-coded connectors, red, white, and yellow, used to transmit analogue audio and video signals. They are typically used to connect older devices, such as DVD players and VCRs, to televisions.
Component
Component cables separate video signals into three components, Y, Pb, and Pr, to deliver higher-quality analogue video. They are often used to connect devices like DVD players and gaming consoles to TVs, providing better video quality than composite cables.
Coaxial
Coaxial cables transmit analogue audio and video signals over a single cable, commonly used for cable television connections. They are also used to connect devices like VCRs and older gaming consoles to TVs.
Optical
Optical cables, also known as TOSLINK cables, transmit digital audio signals using light, providing high-quality sound without electrical interference. These AV cables are commonly used to connect devices like soundbars and home theatre systems to TVs.
