Abstract:
Provided are a method and apparatus for processing a graphic stream. The method may include determining whether a graphic picture is reproducible as a three-dimensional (3D) image by assigning different depth values according to graphic objects or by assigning the same depth value to the graphic picture, using 3D capability information.
Abstract:
A method of transmitting digital broadcasting content for providing 2D content or 3D content. The method includes: encoding content including at least one of the 2D content and the 3D content and generating an elementary stream including encoded data of the content; generating service additional information including electronic program guide (EPG) information of the digital broadcasting content and inserting, into the service additional information, at least one of 2D/3D content identification information representing a method of reproducing the 2D content or the 3D content, 2D/3D content link information representing a relationship between the 2D content and the 3D content, and EPG 3D reproduction information for reproducing an EPG screen, on which EPG information is displayed, in 3D; and generating a transport stream by multiplexing the elementary stream and the service additional information.
Abstract:
A method of processing video images is provided. The method includes reproducing 3-dimensional (3D) video images by generating left-eye video images and right-eye video images from a video stream, receiving a first command for activating a pop-up interactive graphics stream during the reproduction of the 3D video images, and reproducing 2-dimensional (2D) video images by generating either left-eye video images or right-eye video images from the video stream, in response to the first command for activating the pop-up interactive graphics stream.
Abstract:
A method and apparatus for generating a data stream for providing a three-dimensional (3D) multimedia service and a method and apparatus for receiving the data stream are provided. The generating method includes: generating at least one elementary stream (ES) including video data of each view from a program for providing a two-dimensional (2D) or 3D multimedia service; generating program map table (PMT) information about the program, including reference information about the at least one ES and 3D additional information for identifying and reproducing the video data of each view; and generating at least one transport stream (TS) by multiplexing packetized elementary stream (PES) packets generated by packetizing the at least one ES, and the PMT information.
Abstract:
A multimedia stream generating method for 3-dimensional (3D) reproduction of additional reproduction information is provided. The method includes generating a video elementary stream (ES), an audio ES, an additional data stream, and an ancillary information stream that respectively comprise video data, audio data related to the video data, data of additional reproduction information which is to be reproduced together with the video data on a display screen, and additional reproduction information depth information used for 3D reproduction of the additional reproduction information, the video data including at least one of a 2D video image and a 3D video image.
Abstract:
Provided are a method of recording content, a method of providing a title key, an apparatus for recording content, and a content providing server, which can prevent unauthorized users from recording the title key on a plurality of discs. The method of recording content downloaded from a network includes: receiving a title key, which is encrypted with a disc key of a disc on which content is to be recorded in a recording apparatus, from a server; and recording the received title key and the content on the disc.
Abstract:
A metadata generating method including: receiving sub-region dividing information to divide an object into a plurality of sub-regions; and generating sub-region indicating information to indicate each of the plurality of sub-regions divided according to the sub-region dividing information.
Abstract:
A content transmitting method including: generating additional information regarding content including audio/video (A/V) data for multi-angle viewing, wherein the additional information is to be used to record the content; and transmitting the content and the additional information.
Abstract:
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.
Abstract:
A 3D video image processing method including: acquiring three-dimensional (3D) format information of a video image generated from video data to determine a 3D format of the video image; generating, from a first graphic image, a second graphic image corresponding to the determined 3D format of the video image using the 3D format information, the first graphic image being generated from graphic data; and overlaying the video image with the second graphic image.
