LG QRemote Overview
LG QRemote (also known as LG QuickRemote) allows users to use their smartphones as a remote controller to control IR(infrared)-controlled devices such as TVs, DVDs, air-conditioners, etc. LG smartphones which have an IR LED can control the devices through LG QRemote.
IR Remote Control on LG Smartphones
IR(Infrared) light is used in remote controls for various devices. The IR remote controllers send out an IR signal, and the IR receiver in the device recognizes the signal and controls the device. Some of LG smartphones are equipped with an IR LED, which enables users to control devices by sending IR signals. The IR transmitter is usually located on top of the phone.
The IR signals are invisible to the human eyes. Users can check the signals through a camera.
Using LG QRemote
LG QRemote is an application to provide user interfaces for controlling devices such as TVs, DVDs, air-conditioners, etc. Users can register their IR(infrared)-controlled devices, and then control them by tapping buttons on the LG QRemote’s screen.
LG QRemote is known as LG QuickRemote in countries except Korea and Japan.
LG QRemote communicates with IR services to configure and to control devices. Users can control only the devices that are supported by LG QRemote. Users need to configure a device by finding IR codes of basic function to check whether the device is controllable or not. Configuration of the device is done by LG QRemote. Once the device is configured, users can control the device without device information like type, model, or brand name of the device.
LG QRemote stores the list of configured devices. It enables users to deal with many IR-controlled devices with an LG smartphone.
LG QRemote supports the following functions:
• Configuring and registering devices.
• Sending IR signals for processing user-selected functions.
• Creating universal remotes using the IR learning feature.
Developers can create their own remote control applications with the LG QRemote SDK. Detailed information about the SDK is described in the next section.
