Provided are a methods and apparatuses for generating a stereoscopic image format and reconstructing stereoscopic images from the stereoscopic image format. The method of generating a stereoscopic image format for compression or transmission of stereoscopic images includes receiving a base view image and an additional view image, determining block pixel information for the stereoscopic image format for each block position using first block pixel information of the base view image and second block pixel information of the additional view image based on blocks obtained by dividing the base view image and the additional view image, and disposing the determined block pixel information in each block position, thereby generating a combined image including pixel information of the base view image and pixel information of the additional view image.

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.
摘要:
Provided are a method and apparatus for providing and reproducing a three-dimensional (3D) video content, and a computer readable recording medium storing a program to execute the method. The method of providing 3D image content includes: inserting content type information indicating whether the image content is two-dimensional (2D) image content or 3D image content into a reserved region of a Program Map Table (PMT); inserting additional information about the 3D image content into one of an Elementary Stream (ES) descriptor region of the PMT and a reserved region included in a video sequence of the ES; and multiplexing the PMT and the ES of the 3D image content so as to generate a Transport Stream (TS). Accordingly, compatibility with a conventional digital broadcasting system can be maintained and more realistic 3D image content can be provided to a user.
