Abstract: A projection device capable of automatically controlling on/off of a projection module for projecting display data onto an exterior surface according to an open/closed state of a cover of the projection module, and an operation method thereof are provided. The method for operating a projection module in a projection device includes turning-on the projection module when a first detection signal is detected, wherein the first detection signal is generated when a cover of the projection module is open, and after the projection module is turned on, turning-off the projection module when a second detection signal is detected, wherein the second detection signal is generated when a cover of the projection module is closed.

Abstract: Provided are a digital broadcasting receiving device and method for audibly informing a user of a channel change. The method includes searching for channel information and channel audio guide signal premapped to the channel information, upon sensing a channel change, selecting a channel audio guide signal corresponding to the channel information, if channel information about a changed channel exists, and outputting the selected channel audio guide signal through an audio output unit. Thus, the method is capable of informing a user of a channel change by outputting a channel audio guide signal, allowing the user to audibly check a changed channel.
