Still remember that glory days in the world of Nokia, and was named as the king of the N95 mobile phone? In 1995, there were many portals in the 2G era and social software emerged. In 2000, in the 3G era of smart phones, social software became the king. In 2013, in the era of 4G, live streaming and short videos were equally popular, and information flow became a hot topic. Looking back not far away yesterday, digital life quietly came to us, and mobile phones, TV is also upgrading. The once monotonous black and white TV set has been replaced by color LCD TV, allowing us to watch the world at home. Among them, the technology and speed of the development of TV alone has a great appeal, but today I want to talk about not TV technology, but the remote control that goes with it.
The development of remote control can be traced back to the 1950s.
In 1950, zenith electronics ceo John McDonald challenged his engineers to come up with a device that could mute advertisements or redirect them to another channel.
The remote control was born.
At first, it could only be wired to your TV. Five years later, Eugene Polley, an engineer at the same company, developed the first light-beam controlled wireless device called the flashmatic, which earned him the title of father of the television remote control.
But the devices, which can switch channels and adjust the volume, are not widely used because they are difficult to control.

Then, in 1956, Rob Adler developed the Zenith Space Command remote control. It uses the principle of ultrasound to adjust volume and channel. Each key emits a different frequency, but the device is subject to normal ultrasonic interference.
Until 1980, the infrared remote control was born, and it slowly replaced the ultrasonic control device. Infrared remote control is the use of infrared light to transmit instructions, that is, we are the most common long buttons of the remote control.
Remote control development so far, many manufacturers of remote control launched different functions, including voice control, also known as Bluetooth voice remote control, just need to press the voice key of the remote control to talk to the TV, the TV recognition will be operated at the same time. But that certainly didn't achieve the hands-free goal until some brands started offering far-field voice interaction capabilities that let you control your TV with a wake word without ever having to find the remote.
