High-definition 3DTV trial service over terrestrial broadcasting network

This paper presents a three-dimensional television (3DTV) trial broadcasting service that has been recently launched in Korea. The 3DTV trial broadcasting service employs a delivery mechanism of 3D content, called as dual stream method that delivers left and right images over each encoded stream based on MPEG-2 system technology, guaranteeing backward-compatibility. Specifically, this dual stream method is regarded as a proper solution for providing higher image quality both 2D and 3D video. This paper also presents a service mechanism along with signaling method, which enables 2D and 3D service to broadcast in a time-scheduled manner. Finally, we summarize the results of high-definition (HD) 3D trial broadcasting service.
