TRANSMISSION APPARATUS AND METHOD, AND RECEPTION APPARATUS AND METHOD FOR PROVIDING 3D SERVICE USING THE CONTENT AND ADDITIONAL IMAGE SEPERATELY TRANSMITTED WITH THE REFERENCE IMAGE TRANSMITTED IN REAL TIME

摘要

In the present invention, a transmitting apparatus and method and a receiving apparatus and method for providing a 3D service are disclosed. In a transmitting method for providing a 3D service through a connection with a reference image transmitted in real time and additional image and content transmitted separately from the reference image, the transmitting method for providing the 3D service comprises: a real time reference image stream generating step of generating a real time reference image stream on the basis of a reference image and transmitting the generated image stream to a recipient in real time; and an additional image and content transmitting step of transmitting, to the recipient and separately from the reference image stream, additional images and content for providing a 3D service through a connection with the reference image. The real time reference image stream includes connection information, i.e. information related to the additional image and content to be connected to the reference image, and synchronization information for synchronizing the additional image and content with the reference image.
