It seems that the vast popularity of portable digital devices makes watching more private. However, many people claim that they still prefer to spend time watching TV with their family. In this article, we’ll talk about universal TV remote. Read on to know more.
The origin of the remote control
In the 1950s, Eugene F. McDonald, president of Zenith Electronics, posed a problem for the company’s engineers. The thing is, McDonald couldn’t bear to watch the ads on TV anymore and he wanted a device that could silence ads or jump to another channel. In this case, the remote control was invented. McDonald’s wish triggered a significant revolution that changed the way we watch television. We are no longer passive viewers, but more ruthless supervisors. If we don’t like the current program, we can change channels by merely pressing a button.
As a matter of fact, there are many excellent remote-control manufacturers which devote themselves to creating more convenient and portable remote controls. Take Systo as an example. Systo, an expert in remote control for 21 years, is well-known for its pursuit of universal TV remote. The high-quality products and superior services have earned this company a good reputation and enabled it to sell products to the whole world.
The types of remote control
- Bluetooth Remote Control
It is the direct infrared radiation that makes infrared communication technology not suitable for places with many transmission obstacles. In fact, Bluetooth is a kind of wireless technology, which is used to exchange data between fixed and mobile devices over short distances. It forms a personal area network (PAN) by using short-wave and high-frequency radio waves and the ISM band from 2.4 to 2.485 GHz.
- Infrared Remote Controller
As the most common remote control in our lives, the infrared remote control makes use of wireless communication technology and can transmit data by infrared light. That is, it does not need any physical connection and it is free and straightforward to use. In addition, it’s relatively cheap. Hence, the infrared remote control is widely used in small mobile devices to exchange data and control electrical equipment. For example, HUAYU RM-L1130+8 Universal LCD LED TV Remote from Systo attracts more and more customers’ attention. Made of new ABS plastics materials, this exquisite remote control is rather environmentally-friendly and has a longer life cycle. The most important thing is that, equipped with SOP hard seal IC, it supports over 350,000 device models of more than 7,000 smart TV brands.
How remote control works
Before we start to learn about the operation process of universal TV remote, we should first gain some knowledge about the constituent parts of remote control. Generally speaking, there is only one printed circuit board inside a remote control. At the end of the circuit board, there is a light-emitting diode. Besides, there are some electronic components on the circuit board including chips, diodes, transistors, resonators, resistors and capacitors. You can also see a series of contacts correlated with the buttons. The buttons are made of plastic sheets and are attached with a black conductive film.
When you press a remote-control button, a circuit is built because of the connection between the conductive film and the contact. In this way, the chip can detect the circuit and determine which button you pressed. It then sends out Morse code sequence signals corresponding to the button. The signal is amplified by a transistor and is sent to a light-emitting diode. At last, the light-emitting diode converts it into an infrared signal, which can be received by the sensor in the TV.
Now that you’ve gone through enough information we offer, you can certainly make a conscious and informed purchase. Actually, HUAYU RM-L1130+8 Universal LCD LED TV Remote from Systo can be a good choice for you. Don’t hesitate to pick it!
