An apparatus and method for providing multiple screens is disclosed. The apparatus includes a user/application interface module receiving a PiP service providing mode, and an output module displaying a video component of a service on a main screen if the PiP service providing mode is a first mode and displaying a background video or the video component of the service on a PiP screen if the PiP service providing mode in a second mode.

Provided are a method and apparatus for receiving, storing, and executing a data broadcast application. The apparatus includes an application controller that determines whether receiving of application data needed to execute an application is completed before storing of a data broadcast is completed, allows the received application data to be stored when receiving of the application is completed, and determines whether the application will be executed together with audio/video data when the stored data broadcast is reproduced; and a storage unit that stores the completely received application data together with the audio/video data. Accordingly, it is possible to prevent the occurrence of errors in executing an application.

摘要:
Field effect transistors include a semiconductor substrate having a channel region of first conductivity type therein extending adjacent a surface thereof. Source and drain regions of second conductivity type are also provided at opposite ends of the channel region. The source and drain regions extend in the semiconductor substrate and form P-N rectifying junctions with the channel region. A gate electrode extends on the channel region and comprises a first electrically conductive material having a first work function. A first sub-gate electrode extends on the channel region and comprises a second electrically conductive material having a second work function that is unequal to the first work function. The second electrically conductive material is preferably selected so that a difference between the second work function and a work function of the channel region is sufficient to form an inversion-layer in a portion of the channel region extending opposite the first sub-gate electrode when the first sub-gate electrode is at a zero potential bias relative to the channel region.
