Abstract: A mobile cloud system includes a plurality of mobile terminals having at least one functional module and a communicator; a cloud server to receive the information acquired from the at least one functional modules, the cloud server including a read-only file system to provide services applied to all of the plurality of connected mobile terminals, a read/write file system to provide independent services applies to each of the plurality of connected mobile terminals, and a controller to control operations of the both file systems; and a wireless communication network to provide a network between the plurality of mobile terminals and the cloud server.

Abstract: An input/output system and a method for a set-top box using a terminal include making a connection with the terminal including a display unit or a speaker through wired or wireless communication, determining whether the terminal is in a receive enable state for image data or audio data, and sharing the image data or the audio data with the terminal by transmitting the image data or the audio data to the terminal to output an image through the display unit of the terminal or to output audio through the speaker of the terminal, when the terminal is in the receive enable state for the image data or the audio data.
