Why Do TV Remotes Still Use Infrared Technology?
Despite Bluetooth, why is infrared technology still indispensable?
1The History of TV Remotes
The first TV remote, 'Lazy Bones,' was introduced by Zenith Radio Corporation in 1950 and was a wired system. In 1955, 'Flash-Matic' became the first wireless remote, using visible light. Infrared technology became the standard in the 1980s and is still in use today.
2How Infrared Technology Works
Infrared remotes use LEDs to send invisible light signals. The TV's receiver decodes these signals to process commands. This technology works with rapid light pulses that can even be seen through a phone camera.
3The Rise of Bluetooth
Modern TVs now come with Bluetooth-enabled remotes, offering features like voice control and air gestures. However, Bluetooth remotes still include an infrared transmitter because the technology is highly cost-effective.
4Compatibility and Cost Advantage
Infrared technology has become compatible with TVs, soundbars, and other equipment over the years. Abandoning this technology doesn't make sense, especially since Bluetooth and infrared can coexist. The cost is almost negligible.
5The Coexistence of Bluetooth and Infrared
Bluetooth remotes cannot function without pairing. However, infrared is still used for basic functions like turning the TV on and off. This is particularly important when the TV is in standby mode and Bluetooth is inactive.
6The Future Outlook
Infrared technology may continue to serve as an initial pairing method and a reliable backup. However, modern TV remotes mostly use Bluetooth. Bluetooth also allows users to use their phones as remotes.
