The sensing unit 186 senses the current state of the mobile terminal, such as the open / close state of the mobile terminal, the location of the mobile terminal, whether or not the user touches the mobile terminal, and generates a sensing signal for controlling the operation of the mobile terminal. For example, if the mobile terminal is in the form of a slide phone, it senses whether the slide phone is opened or closed, and outputs the sensing result to the controller 180 to control the operation of the terminal. And a sensing function related to whether or not the power supply 127 is powered on, whether the interface 126 is coupled to an external device, and the like.

The interface 126 may include any type of external wireless headset, external charger, wired / wireless data port, card socket (e.g. a memory card, SIM / UIM card) It serves as an interface with the device. The interface 126 receives data from an external device or receives power from the external device, and transmits the data to each component in the mobile terminal or transmits data in the mobile terminal to an external device.

The memory 184 may store a program for processing and controlling the control unit 180 and may have a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, .

In addition, a program for controlling the operation of the mobile terminal related to the present invention is stored in the memory 184

Such memory 184 includes the concept of a generally known hard disk, card type memory (e.g., SD or XD memory), flash memory, RAM, ROM, and the like.

The broadcast receiving module 185 receives broadcast signals transmitted through satellite or terrestrial waves and converts the received broadcast signals into broadcast data types that can be output to the sound output units 114 and 131 and the display unit 113 and outputs the broadcast data formats to the controller 180. In addition, the broadcast receiving module 185 receives additional data (e.g., EPG (Electric Program Guide), channel list, etc.) related to broadcasting. The broadcast data and the additional data converted by the broadcast receiving module 185 may be stored in the memory 164.

The power supply unit 127 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.
