Imagine yourself in an amazing entertainment room. You have a large, flat-screen TV, przestrzennysystem sound speakers and a Blu-ray high definition. Most of the equipment installed in a sturdy locker under console storage under the TV, preventing the excessive number of cables in the room. Add to that comfy sofa, popcorn at the ready and a few remotes at the IR port on this little table right next to you. You may think that everything is ready, but what if you have a problem with controlling other connected devices using the pilots on the locker? What to do if you have additional speakers, or the extra monitor in the next room, and the infrared signals are not strong enough to get that far? The same thing if this console to the console serving your television and the case of Your Blu-ray player, made of heavy wood, and completely covers your equipment, obstructing the distant signals to reach? Each and every one of these reasons:Remote IR extender can help to solve this problem.
The amplifier for the infrared port (IR-port), also known as amplifier , receiver is designed for receiving the infrared signal from the remote controller and transmit it via radio frequency to the controlled device. Given our extensive locker, a potential difficulty arises when the IR signal reaches the Blu-ray player when it’s hidden and invisible. Although, of course, makes sure the room looks neat, and the IR signal can reach the player, as if his line of vision to the device was more direct. In response to this signal obstacles between the remote control and a Blu-ray player, infrared remote control transmitter is introduced between the remote control and the device. Transmitter podczerwienina the target device will simulate the original signal IR to the Blu-ray player to interpret the remote item in the usual way without the use of an extension cord. As mentioned earlier, this is particularly useful in situations where the line of vision of the pilot is hidden or if you plan to control equipment from another room, and requires a special signal.
Amplifier system IR has several components, including purpose , connection block and the radiator . The goal is a fancy way of binding to the IR receiver, which converts these light waves in the infrared range, transmitted from the remote control into electrical signals for distribution. The emitter (or IR transmitter) converts the signals to electrical and back to modulated signals in the IR band, where they are transmitted via light waves to the device that you are trying to manage (i.e., our Blu-ray player inside the case). The IR receiver usually is added to the target device through the port on the receiver. As the name implies, block połączeniajest the main center in which all parts of the receiver system is connected and related to each other. Connection block, which makes such systems easy to expand and change the configuration depending on the configuration of the entertainment.
To expand your range
As in the case of many products associated with a particular configuration of entertainment, what are you going to use it, as well as placement of equipment, determine what type of remote IR extender is the best. For example, if you have a large house with multiple monitors installed in an adjacent room, the words will find the amplifier IR Oh, long the area of the infrared radiation , especially if the signal received from the light-emitting diodes (LED) of the remote control needs to go through walls and cabinets that store your devices. Some extenders provide a signal range of up to five or six hundred feet.
Easy installation is also key. Because you will be working with several different parts and several cables, making sure the installation instructions are simple, to run as fast as possible.
If you have a lot of equipment in the house, one or two transmitters can not cope with this problem, because each item of equipment needs its own special transmitter to correctly receive the signals from the remote control. Some extenders offer LEDs confirming the LED to let you know that the signal was properly distributed. This is useful when we are dealing with several independent devices located in different rooms.
Short reaction time is another integral piece of the puzzle extender. If this goes on for an eternity before the signal amplifier interpretirovat and transmits the signals of your equipment, does not make sense to use this amp in the first place. The reaction time should be smooth and barely noticeable.
The evolution of infrared technology
The first remote intended to control a television was developed by Zenith Electronics in 1950 and was called the Lazy Bone. While the pilot can turn on and off the TV and switch channels, it was connected to the TV by a thick cable that was the danger of tripping. In 1955 Zenith Engineer Eugene Polly, created the first wireless remote control called Flash-matic , which used a directional flashlight to activate the four control functions on the TV. This project was problematic due to interference caused by natural sunlight.
In 1956, Robert Adler invented the remote control, the Zenith Space Command , which was based on the concept of using ultrasound technology to change the channels. The device at the infrared port eventually replaced ultrasonic remote controls in the early 80s, entering the growing need and popularity of remote extender infrared. Remote control, IR remote control, as ekstendery are still in use.
