Abstract:
Provided is a metadata structure for storing and re-producing stereoscopic data and a method for storing a stereoscopic content file based on the metadata structure. The stereoscopic content file storing method includes storing streams of the stereoscopic contents; and, when the stereoscopic content has more than two elementary streams, storing information for dividing the elementary streams into a main track and a supplementary track.
Abstract:
A method and apparatus for providing 3D still image service in a specific time interval during audio-visual service of digital broadcast are provided. The method includes receiving a reference image and a 3D supplement image, which construct a 3D still image, through a data channel or a video channel together with a 2D image; restoring the reference image and the 3D supplement image to the 3D still image; and displaying the 3D still image in a specific interval during digital audio-visual broadcast using the 2D image according to display information which includes a play time and a play mode.
Abstract:
An apparatus and a method for synchronizing and providing a stereoscopic image are provided. The method includes storing a first image, receiving a second image that forms a stereoscopic image with the first image correlated, synchronizing the first image and the second image, and outputting the synchronized two images.
Abstract:
A stereoscopic data processing method and apparatus to provide service of stereoscopic data interoperating with digital multimedia broadcasting (DMB) is provided. The stereoscopic data processing method, including: receiving a transmission stream (TS) including a program map table from an external device; recognizing stereoscopic program information descriptor in the program map table; and recognizing defined bit values in the stereoscopic program information descriptor and processing data.
Abstract:
Provided is an object description and multiplexing method which provides an object descriptor of a new structure and a multiplexing method for a 3D still image service based on DMB, such as 3D still image advertisement service, and provides 3D a user with still image service through interaction with the user at a specific time or specific video scene while maintaining compatibility with conventional DMB services, and a decoding apparatus and method using the object description and multiplexing method. The method for describing an object to provide a 3D still image service based on DMB, which includes: deciding a broadcasting type of a still image service to be broadcasted between two-dimensional broadcasting and 3D broadcasting based on a program information descriptor in a program map table; and describing reference still image and additional still image that are transmitted separately for the 3D still image service with relation to each other.
