20100266052METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING ENHANCED MEDIA DATA IN DIGITAL MULTIMEDIA BROADCASTING SYSTEM - A method and apparatus for processing enhanced media data in a Digital Multimedia Broadcasting (DMB) system is provided. The apparatus for processing enhanced media data includes: a base layer processing unit configured to multiplex an elementary stream of a base layer and perform channel encoding for the multiplexed elementary stream of the base layer; an enhancement layer processing unit configured to synchronize an elementary stream of an enhancement layer with the elementary stream of the base layer and thereby multiplex the elementary stream of the enhancement layer and process the elementary stream of the enhancement layer to be transmittable via at least one of a plurality of transmission channels; and a synchronizer configured to provide the enhancement layer processing unit with synchronization information that is used for synchronizing the elementary stream of the enhancement layer with the elementary stream of the base layer.10-21-2010
20100315486STEREOSCOPIC VIDEO SERVICE PROVIDING/RECEIVING METHOD AND APPARATUS IN DIGITAL BROADCASTING SYSTEM - Provided is a stereoscopic video service providing method using a stereoscopic video stream including first and second video streams in a digital broadcasting system. The stereoscopic video service providing method includes: generating information on the first video stream and information on the second video stream; inserting an identifier of the information on the second video stream into the information on the first video stream; and transmitting the first video stream and the information on the first video stream and the second video stream and the information on the second video stream through separate transmission channels, respectively.12-16-2010
20110010739METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING STEREOSCOPIC VIDEO IN DIGITAL BROADCASTING SYSTEM - Provided is a method for transmitting a stereoscopic video in a digital broadcasting system, the stereoscopic video being composed of a left view and a right view. The method includes: generating information indicating that the video is stereoscopic, information about a composition type of the stereoscopic video, and additional information based on the composition type; and transmitting the stereoscopic video and the generated information. The composition type is to compose the stereoscopic video of a single or two encoding streams by using the left view and the right view. In the case of a single stream mode in which the stereoscopic video is composed of the single encoding stream, the additional information includes information about positions of the left and right views. In the case of a dual stream mode in which the stereoscopic video is composed of the two encoding streams, the additional information includes information indicating whether the respective encoding streams are the left view or the right view and information indicating correlation between the respective encoding streams.01-13-2011
20110050857APPARATUS AND METHOD FOR DISPLAYING 3D IMAGE IN 3D IMAGE SYSTEM - Disclosed is an apparatus and a method for displaying 3D images, which do not need to be reversed, so that users can watch the 3D images without modification in a 3D image system. The 3D images display extracts characteristic information regarding a plurality of imaging devices from left and right images taken by the imaging devices, selects an image among the left and right images, determines a reference element in the selected image, determines a selection element corresponding to the reference element in the non-selected image; calculates a disparity value between the left and right images by using the reference element and the selection element, determines whether the left and right images are normal or not by using the disparity value, and corrects the left and right images based on the determination result.03-03-2011
20110141364METHOD AND APPARATUS FOR RECEPTION AND TRANSMISSION - Disclosed is a reception apparatus including a basic service reception unit to demodulate and channel-decode a signal received through one broadcasting channel among broadcasting channels for a basic service, and to extract a transport stream, an additional service reception unit to demodulate and channel-decode a signal received through a broadcasting channel for an additional service combined with the basic service, and to extract a transport stream, an integrated demultiplexer to respectively demultiplex the transport stream provided for the basic service and the transport stream provided for the additional service in order to extract at least one transport stream, and a source decoder to respectively decode the demultiplexed transport stream provided for the basic service and the demultiplexed transport stream provided for the additional service in order to broadcast at least one of a basic source and an additional source combined with the basic source.06-16-2011
20110242093APPARATUS AND METHOD FOR PROVIDING IMAGE DATA IN IMAGE SYSTEM - An apparatus for providing image data in an image system includes: a stereoscopic image generation unit configured to receive image data and depth information data and generate stereoscopic image data; a parallax calculation unit configured to analyze parallax information of a 3D image from the stereoscopic image data, divide the analyzed parallax information step by step, and determine parallax step information; a caption and text generation unit configured to generate a caption and a text by applying the parallax step information and generate position information of the generated caption and text; and an image synthesis unit configured to insert the caption and text into the stereoscopic image data based on the position information of the caption and text and provide 3D image data.10-06-2011
20120005715APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING DATA IN COMMUNICATION SYSTEM - Provided is an apparatus and method for transmitting and receiving broadcasting data and supplementary data. The method includes: generating broadcasting data and supplementary data for a plurality of predetermined 3D broadcasting services to be provided to users; multiplexing the generated broadcasting data for broadcasting channels respectively allocated to the plurality of predetermined 3D broadcasting services, and multiplexing the generated supplementary data for one commonly broadcasting channel commonly allocated to the plurality of predetermined 3D broadcasting services; encoding the multiplexed supplementary data corresponding to a conditional access system; and transmitting the encoded supplementary data to the one common broadcasting channel, and transmitting the multiplexed broadcasting data to the allocated broadcasting channels.01-05-2012
20120033035METHOD AND SYSTEM FOR TRANSMITTING/RECEIVING 3-DIMENSIONAL BROADCASTING SERVICE - Provided is a method and system of transmitting and receiving a three-dimensional (3D) broadcasting service, and more particularly, to a method and system for transmitting and receiving a reference image and a 3D auxiliary image for the 3D broadcasting service through a digital broadcasting network in real-time or in non-real time. According to the present invention, a smooth broadcasting service may be provided to terminals receiving a two-dimensional (2D) or 3D broadcast.02-09-2012
