  • Patent number: 10249179
    Abstract: Embodiments of the disclosure provide a method an device for transmitting a control signal in a multi-device system, where a first device determines a second device to be controlled by a remote controller of the first device to be connected with the first device; determines from a received signal a first value of the button for controlling the first device; determines a second value of the button, corresponding to the first value of the button, for controlling the second device; and transmits the second value of the button to the second device, so that the second device operates according to the received second value of the button, and with this technical solution, a multi-device system can be controlled by the remote controller of the single device without infrared learning by the first device to thereby simplify operations of the first device to control the other device.
