TV Remote Bluetooth: When smartphones, smartwatches and even smart TVs have Bluetooth, why don’t TV remotes have Bluetooth? Have you ever wondered why TV remotes are still stuck with infrared when all modern gadgets come with Bluetooth connectivity? The answer and reason for this is very simple. Before knowing this, let us know how TV remotes work and why decades old technology is still being used in them.
How do infrared remotes work?
The trend of infrared remote started in the 1970s and 80s. These remotes, which replaced the ultrasonic clicker, soon became popular and started being used in everything from TV, projector to air conditioner. Their way of working is very easy. A microprocessor installed in the remote creates binary code. The emitter installed in the remote encodes this code as pulses of light, which are flashed towards the device. The front device decodes that light and converts it into commands. This is the way that when you press the button on the remote, the channel on the TV changes.
Why is decades old technology still being used today?
In the last few years, the appearance of almost all the gadgets including TV has changed, so it is natural to raise the question as to why decades old technology is still being used in the remote. In answer to this, many things like low cost, reliability, power efficiency and simplicity can be counted. This means that using infrared, which has been in use for many years in TV remotes, is cheaper, it is more reliable and it consumes less power compared to wireless technology. To use it, companies do not have to pay any utility fees. Due to these reasons, even today companies are using infrared instead of Bluetooth in TV remotes.
