摘要:
A method and apparatus for providing a three-dimensional (3D) image is provided. In the method, first-viewpoint image data and second-viewpoint image data that provide a 3D image are obtained. Time information that represents points of time that the first-viewpoint image data and the second-viewpoint image data are to be processed is produced, based on relation information to indicate that the first-viewpoint image data and the second-viewpoint image data are a pair of pieces of image data. The first-viewpoint image data, the second-viewpoint image data, and the time information are transmitted. The first-viewpoint image data is transmitted in a first stream, and the second-viewpoint image data is transmitted in a second stream.

A receiver is provided. The receiver includes a first receiving unit which receives a first stream over a broadcasting network; a second receiving unit which receives a second stream over a communication network; a data processing unit which detects aggregation information from at least one of the first and second streams, and which assembles and processes data of the first stream and data of the second stream according to the aggregation information; and an output unit which outputs the data processed by the data processing unit. Thus, relevant data can be assembled and processed easily.

摘要:
An image processing method and apparatus and an image generating method and apparatus, the image processing method to output a video data being a two-dimensional (2D) image as the 2D image or a three-dimensional (3D) image including: extracting information about the video data from metadata associated with the video data; and outputting the video data as the 2D image or the 3D image by using the extracted information about the video data.
摘要:
A method and an apparatus for transmitting and receiving a broadcasting stream for providing a digital broadcasting service including a subtitle service are provided. A method of transmitting a data stream includes: generating a subtitle stream including basic viewpoint subtitle data and additional viewpoint subtitle data to reproduce a three-dimensional (3D) subtitle on a video screen on which video data is reproduced; determining 3D subtitle reproduction information for forming the 3D subtitle on the video screen based on the basic viewpoint subtitle data; and outputting a data stream by multiplexing a video stream including the video data, the 3D subtitle reproduction information, and the subtitle stream.
摘要:
An image decoding method, an image outputting method, an image decoding apparatus and an outputting apparatus, the image outputting method including inputting an image; and if determined that the input image is a video image that is overlaid with a graphic image, outputting an area of the input image, which is overlaid with the graphic image, as a 2-dimensional (2-D) image and outputting the other area of the input image, which is not overlaid with the graphic image, as a 3-dimensional (3-D) image; and if determined that the input image is a video image that is not overlaid with a graphic image, outputting the input image as a 3-D image.
摘要:
An image processing method and apparatus to output video data, which is a two-dimensional (2D) image, as a three-dimensional (3D) image, the image processing method including: when a current frame of the video data is classified as a new shot that is different from a shot a previous frame of the video data that is output temporally before the current frame, estimating a motion of the current frame by using one or more next frames of the video data that are output temporally after the current frame and are classified as the new shot; and outputting the current frame as the 3D image by using the estimated motion.
摘要:
A method and apparatus for processing a signal, including: extracting three-dimensional (3D) reproduction information for reproducing a subtitle, which is reproduced with a video image, in 3D, from additional data for generating the subtitle; and reproducing the subtitle in 3D by using the additional data and the 3D reproduction information.
