RF remote control - Computer Definition
(Radio Frequency remote control) A handheld, wireless device used to operate audio, video and other electronic equipment using radio frequency (RF) transmission. Unlike the more common infrared (IR) remotes, RF remotes do not require line of sight and do not have to be aimed at the equipment. In fact, RF remotes can be operated from another room. RF Receivers (Base Stations) Are Required Most A/V equipment is IR based and has an IR sensor on the front panel. Because RF remote control signals must wind up as IR signals at the IR sensors, an RF receiver (base station and antenna) accepts RF and converts it to IR. Receivers are wired to an "IR emitter" (flasher) pasted onto the sensor of each device or to an "IR blaster" located inside the home theater cabinet. The blaster reflects off the closed cabinet door, showering IR signals to all the devices at the same time. See IR remote control and RF.
