Abstract:
PURPOSE: A method and apparatus for generating data stream to provide 3D multimedia service is provided to offer a 2D multimedia service regardless of 3D additional information and reference information. CONSTITUTION: An apparatus creates one or more ES(Elementary Stream) among programs for a 2D or a 3D multimedia service(1510). The apparatus creates PMT(Program Map Table) information which includes reference information about one or more ES and 3D additional information(1520). The apparatus creates TS(Transport Stream) through a multiplex of a PES(Packetized Elementary Stream) packet(1530).
Abstract:
A method and an apparatus for providing customized contents are provided to automatically search contents by mark log information and supply contents suitable for a person. Selected contents are displayed(210~240). Log information according to marking is generated on the displayed contents(250). Contents related to the mark log information are searched in a network and linked with the mark log information(252~264). The mark log information is recorded information displayed by a user. The mark log information is additionally defined by the user or a manufacturer. The marking log information is classified into various link information defined by the user or the manufacturer. If it is checked offline when the mark log information is generated, the marking log information is stored in an additional repository(272).

Abstract:
PURPOSE: A transmission system for providing a hybrid service, a receiving device thereof and a service providing method thereof are provided to selectively provide the hybrid service using an information describer. CONSTITUTION: A first signal processing unit (230) processes reference data detected from a demultiplexer unit. If a service is determined as a hybrid service by an information describer, a control unit (240) controls a second receiving unit to access a source device corresponding to supplementary data reference information. A second signal processing unit (260) receives a second signal including additional data from the source device through an IP communications network. The second signal processing unit processes the additional data. An output unit (270) synchronizes the reference data processed in the first signal processing unit and the additional data processed in the second signal processing unit and outputs synchronized data of the reference data and the additional data.

Abstract:
PURPOSE: A content display method, a content synchronizing method thereof, a broadcast content display method thereof, and a display device thereof are provided to update only changed elements for a currently consumed multimedia service in real time by delivering only composition information about change target elements. CONSTITUTION: A broadcast content display device receives initial scene composition information about contents from an external device to analyze and structurize the information(S210, S220). The device renders the contents according to the initial scene composition information(S230). The device receives additional scene composition information about the contents from the external device(S240). The device updates the structurized initial scene composition information(S250). [Reference numerals] (AA) Start; (BB) End; (S210) Receiving initial scene composition information; (S220) Analyzing and structurizing the initial scene composition information; (S230) Rendering the content; (S240) Receiving additional scene composition information; (S250) Updating the structurized initial scene composition information;
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).
