Smart TVS are indeed capable of processing infrared signals and can be controlled with an infrared remote control. Here is a detailed explanation of how smart TVS handle infrared signals, along with some practical examples.
- Smart TV and infrared signal processing
Smart TVS, like traditional TVS, are equipped with infrared receivers to receive signals from infrared remote controls. These signals are invisible to the human eye and need to be transmitted in a straight line, so users need to point the remote control at the TV when using the infrared remote control.
- Signal coding and recognition
Each time the user presses a button on the infrared remote control, the microprocessor inside the remote control converts the key action into a specific coded signal. This encoded signal is a series of ordered and precise infrared pulses that contain control commands, such as adjusting the volume and changing the channel.
- Signal reception and execution
The infrared receiver inside the smart TV receives these pulse signals and sends them to the TV’s internal microprocessor. The microprocessor interprets these encoded signals and performs actions based on the instructions in the signals, such as opening an app, adjusting the volume, or switching input sources.
- Give an example
Suppose the user is using an infrared remote control to control a smart TV. When the user presses the “Volume +” button, the remote emits a specific infrared pulse sequence that is captured by the smart TV’s infrared receiver. The smart TV’s microprocessor recognizes this sequence and translates it into a command to increase the volume, which then increases the volume of the TV.
- Multi-device control
The infrared receiver of the smart TV is capable of processing signals from multiple infrared remote controls. For example, a user might have one remote control dedicated to controlling the TV and another for controlling the set-top box. Smart TVS can distinguish these signals by built-in logic and perform actions accordingly. If the user uses a universal infrared remote control, this remote control can “learn” the infrared signal of different devices, so that one remote control can control multiple devices.
- Advantages of smart remote control
Intelligent remote control, also known as infrared repeater, can control electrical equipment controlled by infrared remote control, such as TV, CD player, power amplifier, air conditioning, etc. They join the intelligent remote control by learning, and for the fixed infrared control signals used by commonly used large brands of electrical appliances, such as air conditioners, televisions, etc., the intelligent remote control is controlled by built-in or directly downloaded from the network.
- Conclusion
The smart TV processes the signals from the infrared remote control through its built-in infrared receiver and is able to recognize and execute the commands that these signals represent. This allows users to easily control the various functions of the smart TV, and at the same time, the emergence of the smart remote control further enhances the flexibility and convenience of this control.
