    • A radio-frequency (RF) remote control (10) has a user interface and transmits an RF signal (11) which designates a device (14) to be controlled and a command for that device. The RF signal is received by an intermediary device (12). The intermediary device, in turn, generates and broadcasts a plurality of high-power IR signals (13A-13F). These signals may be received directly by a controlled device (14A) or may be received indirectly by a controlled device (14B, 14C) after one or more reflections from objects (16A, 16B) and/or room surfaces (18). Thus, reliable control of the devices (14) is obtained even in situations where merely transmitting a typical IR signal may not provide reliable control of the device (14).
    • 射频(RF)遥控器(10)具有用户接口,并发送指定要控制的设备(14)的RF信号(11)和用于该设备的命令。 RF信号由中间设备(12)接收。 中继装置又产生并广播多个高功率红外信号(13A-13F)。 这些信号可以由受控设备(14A)直接接收,或者可以在来自对象(16A,16B)和/或室内表面(18)的一次或多次反射之后由受控设备(14B,14C)间接接收。 因此,即使在仅发送典型的IR信号的情况下也可以不对设备(14)提供可靠的控制,因此可以获得对设备(14)的可靠控制。
