Embodiment Construction

[0016] Hereinafter, the hierarchical broadcasting system and method for 3D broadcasting according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0017] The basic principle of the present invention for supporting three-dimensional broadcasting is that the broadcast transmission system transmits the first broadcast data used for the existing broadcast to the broadcast receiving system through the first communication network, and the broadcast transmission system transmits the first broadcast data used for the existing broadcast through the second communication network. The second broadcast data in the 3D image broadcast is transmitted to the broadcast receiving system, wherein the second communication network may be a different communication network from the first communication network or the same communication network as the first communication network. In this case, the broadcast receiving system can combin...

Abstract

A hierarchical broadcasting system and method for three-dimensional broadcasting is proposed. The hierarchical three-dimensional image broadcasting method includes: allowing the broadcast transmission system to transmit the first broadcast data used for the existing broadcast to the broadcast receiving system through the first communication network; and allowing the broadcast transmission system to transmit the first broadcast data used for the three-dimensional image through the second communication network The broadcasted second broadcast data is sent to the broadcast receiving system. In this case, the broadcast receiving system may combine the first broadcast data and the second broadcast data to display a three-dimensional image broadcast.

Description

technical field [0001] The present invention relates to a hierarchical broadcasting system and method for 3D broadcasting, in particular, to a system and method for providing 3D image broadcasting using different heterogeneous networks or the same network. Background technique [0002] Although terrestrial digital broadcasting performs high-quality broadcasting by providing higher resolution than analog broadcasting, there is an increasing demand for three-dimensional images that allow images to be viewed more realistically regardless of the moving direction and speed of objects. [0003] In order to provide a three-dimensional image, image data of at least two or more viewpoints must be transmitted. However, it is difficult to provide three-dimensional images due to insufficient current broadcast frequencies and compatibility issues with current broadcast devices. [0004] Therefore, there is a need for a broadcasting system and method that can provide three-dimensional im...
