Abstract: The present disclosure relates to technologies for sensor networks, a machine-to-machine (M2M) interface, machine-type communication (MTC), and an Internet of things (IoT). The present disclosure may be used in intelligent services (e.g., a smart home, a smart building, a smart city, a smart car, a connected car, health-care, digital education, a retail business, security and safety-related services, etc.). A service-oriented input and output method and apparatus for a smart control system are provided. The method includes receiving a hot key input from a remote controller, transmitting a command corresponding to the hot key input to a device corresponding to the command, receiving a processing result according to the command from the device, when a display is inactivated upon reception of the processing result, activating the display and outputting a message according to the processing result through the display, and inactivating the display after the output of the message is ended.

Abstract: A connector is providing for reducing near end cross-talk (NEXT). The connector includes a first pin set having sequentially arranged pins configured to transmit a uni-directional signal, a single ended pin adjacent to the first pin set, and a second pin set having sequentially arranged pins adjacent to the single ended pin and having sequentially arranged pins configured to transmit a bi-directional signal.

Abstract: A projector and method of controlling a projector, the projector including: a projection unit configured to project an image; first and second sensors which are disposed to be centered about the projection unit and configured to detect a motion of an object; and a control unit configured to control the projector if the motion of the object is detected by at least one of the first and the second sensors, wherein an axis of detection of the first sensor intersects an axis of detection of the second sensor.
