Abstract: Provided are a server and method for providing three-dimensional (3D) video content and a device for playing video content. A 3D video content service server includes a server communication module, a server memory, and a server processor. When user interaction editing information for 3D video content is input, the server processor edits a user interaction for the 3D video content according to the user interaction editing information and generates and stores metadata for the edited user interaction.

Abstract: A 3D image synthesizing apparatus models a background to be imaged for each of positions to generate a background model at each of positions, sets a first IAD of a camera at each position based on the background model at each position, obtains a 3D image of the background imaged by the camera based on the first IAD, selects a target position corresponding to an object to be imaged from among the positions, sets a second IAD of the camera at the target position based on the first IAD set at the target position, obtains a 3D image of the object imaged by the camera based on the second IAD, and synthesizes the 3D image of the background and the 3D image of the object.
