The sensing unit 186 detects a current status of the watch type mobile terminal such as the location of the watch type mobile terminal, the presence or absence of user contact with the watch type mobile terminal (i.e., touch inputs), whether or not the buckle unit 130 is connected, and the like, and generates commands or signals for controlling the operation of the watch type mobile terminal. Also, the sensing unit 186 handles a sensing function related to whether or not the power supply unit 170 supplies power, whether the interface unit 188 is coupled with an external device.
The interface unit 188 serves as an interface by which at least one external device may be connected with the watch type mobile terminal. For example, the external devices may include wired or wireless headset ports, an external power supply (or battery charger) ports, wired or wireless data ports, card socket for accommodating a SIM (Subscriber Identification Module) card or a UIM (User Identity Module) card. The interface unit 188 may be used to receive inputs (e.g., data, information, power, etc.) from an external device and transfer the received inputs to one or more elements within the watch type mobile terminal or may be used to transfer data between the mobile terminal and an external device.
The memory 184 may store software programs or the like used for the processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, video, etc.) that have been outputted or which are to be outputted.
The memory 184 stores a program for controlling the operation of the watch type mobile terminal according to an exemplary embodiment of the present invention. The memory 184 includes at least one type of storage medium including a Flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Read-Only Memory (ROM), etc.
The broadcast receiving module 185 receives broadcast signals and/or broadcast associated information from an external broadcast management server (or other network entity) via a broadcast channel, converts them into a broadcast data form that can be outputted to the display unit 113, and outputs the same to the controller 180. Also, the broadcast receiving module 185 receives supplementary data (e.g., electric program guide (EPG), a channel list, and the like) related to a broadcast. The broadcast data and supplementary data converted in the broadcast receiving module 185 may be stored in the memory 184.
The power supply unit 189 receives external power (via a power cable connection) or internal power (via a battery of the mobile terminal) and supplies appropriate power required for operating respective elements and components under the control of the controller 180.
