摘要： A low power detection apparatus and a method for displaying information are provided. When a low power manager drives a proximity detection sensor to generate a proximity interrupt in a state within which the portable terminal is in an idle state, the low power manager drives a motion detection sensor and determines a motion of the portable terminal for a preset time. When there is no motion of the portable terminal for the preset time, the low power manager generates proximity data for displaying screen information and then transmits the generated proximity data to an application processor so as to display screen information which the user desires with low power.

摘要： A media clock recovery device, a method for recovering media clock, and an electronic device are provided. The media clock recovery device comprising processing circuitry configured to determine whether a time stamp is normal, the time stamp being received in a packet through a network, calculate an average time interval of a dummy time stamp, the calculated average time interval of the dummy time stamp being used for generating a media clock in response to determining the time stamp is not normal, generate the dummy time stamp based on the calculated average time interval of the dummy time stamp, wherein the processing circuitry is configured to determine the time stamp is not normal, in response to the packet not being received within a time threshold value from a reception time of a previously received packet.

摘要： Context recognition methods and apparatus are provided for an application processor and a micro control unit. It is determined whether an operation switch condition for switching to a sleep mode is satisfied. A request for execution of a context recognition function is sent to a micro control unit, when the operation switch condition is satisfied. The application processor switches to the sleep mode, when the context recognition function is executed by the micro control unit. The micro control unit collects sensor data at previously stored time intervals, and previously stored state information is updated based on the sensor data.
