PURPOSE: A device for providing a 3D service by interlinking a separately transmitted additional image with a reference image transmitted in real time and a method thereof are provided to form a high definition 3D service by inserting a signaling plan for a reference relation between two images and time information. CONSTITUTION: A real time reference image stream is decoded as a reference image(10) through a reference image generator(130). The real time reference image stream is delivered to a 3D play unit(160). Interlinking information and synchronization information in the real time reference image stream are delivered to a reception and storage unit(150). The reception and storage unit delivers a file or an additional image-related stream to be interlinked with the reference image and an additional image(20) synchronized with the reference image to the 3D play unit through the interlinking information and the synchronization information.

Abstract:
PURPOSE: A remote control method of a display apparatus and apparatus thereof are provided to enable a user to control additional services provided by a display apparatus by receiving control information. CONSTITUTION: A control information input unit(124) receives control information for a display apparatus from the outside. A control image output unit(121) displays a graphic image for receiving the control information. A second control unit(122) provides the graphic image to the control image output unit. The second control unit receives the control information from the control information input unit. The second control unit converts the inputted control information into a control signal recognized by the display apparatus. A second data transmission and reception unit(123) transmits the converted control signal to the display apparatus.

PURPOSE: An apparatus and a method for reconstructing an intermediate view are provided to process border noise generated by intermediate image synthesis. CONSTITUTION: An image acquisition unit(110) obtains two or more multi-view reference images filmed at various points of time. A three dimensional conversion unit(120) warps the obtained reference image three-dimensionally. The three dimensional conversion unit synthesizes an intermediate image. An intermediate image compensation unit(200) removes boundary noise or common hole generated from the intermediate image. A boundary noise processing unit(210) detects/removes only the boundary noise.
