Abstract:
A display apparatus and a text output method thereof are provided. The text output method of a display apparatus acquires character information; determines character correction information for character information in accordance to at least one of the characteristic of the display apparatus and the characteristic of an input character; generates a contour line of the character based on the character information and the character correction information to perform rendering; and outputs the rendered character.
Abstract:
PURPOSE: A multi stream generating method, a device, a receiving method and a device thereof are provided to solve inconvenience that a user can feel improper depth sense between video and additional reproduction information. CONSTITUTION: A program encoding unit(110) generates a video ES stream, audio ES stream, an optional data stream and a supplementary information stream. The program encoding unit generates a video PFS packet, a video PES packet, an additional data PES packet and an optional information packet by packing the video ES stream, the video ES stream, and the additional data stream. A TS stream generating unit(120) generates a TS stream by multiplexing the video PES packet, the video PEX packet, the additional data PES packet, and the supplementary data packet.

PURPOSE: A method and apparatus for transmitting a video data stream for providing a digital broadcasting service including a subtitle service and a method and apparatus for receiving a video data stream for providing a digital broadcasting service including a subtitle service are provided to transmit and receive basic timing subtitle data and additional timing subtitle. CONSTITUTION: A video data stream transmitting apparatus generates a subtitle stream including basic timing subtitle data and additional timing subtitle data(1010). A 3D subtitle reproduction information is determined for constructing a 3D subtitle(1020). A video stream including video data, the subtitle stream, and a PMT(Program Map Table) section is multiplexed and a TS(Transport Stream) packet is outputted(1030).

Abstract:
PURPOSE: A signal processing method and an apparatus thereof for generating supplementary data generated with a video image in three dimensions are provided to extract three dimensional generation information for generating a subtitle in three dimensions from the supplementary data. CONSTITUTION: Three dimensional reproduction information for reproducing as a three-dimensional subtitle is extracted from additional data. A TS stream generating unit(120) generates a subtitle in a video. The subtitle is generated in three dimensions by using three-dimensional reproduction information and additional data.

Abstract:
PURPOSE: A display device, a signal processing device and methods thereof are provided to prevent the screen reversal when a graphic object is outputted with a video output. CONSTITUTION: A video processing unit processes a video signal. A graphic processing unit processes a graphic data. A display unit displays an image and a graphic object. A control unit gives a different stereoscopic effect to the image and the graphic object, respectively. The control unit controls the video processing unit and the graphic processing unit to maintain that the graphic object is displayed on an overlay layer(20) which is upper layer than a reference layer(10).
Abstract:
PURPOSE: A method for generating a data stream to display 3D user recognition information, a device thereof, a method for playing thereof, and a device for playing thereof are provided to display the recognition information to show a play mode of a display device with video content on a screen. CONSTITUTION: A video data inserting unit inserts the video data of 2D or 3D video content into a data stream(2510). A 3D user recognition information inserting unit and a recognition information related information inserting unit insert 3D user recognition information, recognition information inserting information, and display authority information into the data stream(2520). A transmitting unit transmits the data stream with the video data(2530).
