In this comprehensive guide, we’ll delve into the world of IR blasters, exploring their function, benefits, and limitations.
What is an IR Blaster?
An IR blaster, also known as an infrared blaster, is a feature found in some TVs that allows them to control other devices connected to them. But before we dive deeper, let’s first understand what IR technology is.
IR (Infrared) technology is a line-of-sight communication method that uses infrared light to transmit signals between devices. It’s the same technology used in TV remotes, where the remote sends IR signals to the TV, which then responds accordingly. In the context of TVs, an IR blaster is essentially an IR transmitter that can mimic the signals sent by a device’s original remote control.
How Does an IR Blaster Work?
When an IR blaster is enabled on your TV, it can send IR signals to other devices connected to it, such as a set-top box, DVD player, or soundbar. This allows your TV to control these devices as if you were using their original remotes. The IR blaster can be set up to learn the IR codes of these devices, allowing it to send the correct signals to control their functions.
For example, if you have a set-top box connected to your TV, you can use your TV’s remote control to change channels, adjust the volume, or access the set-top box’s menu, all without using the set-top box’s original remote. This can be especially useful if you have a cluttered coffee table or if you’re prone to misplacing remotes.
Built-in IR Blaster vs. External IR Blaster
There are two types of IR blasters: built-in and external.
Built-in IR Blaster: Some TVs come with a built-in IR blaster, which is usually located on the front or top of the TV. This built-in IR blaster is usually a small LED or a series of LEDs that transmit the IR signals.
External IR Blaster: An external IR blaster is a separate device that connects to your TV via a cable. It’s usually a small device with an IR LED that can be placed near the devices it needs to control.
