Abstract
This paper presents 8-VSB & M/H hybrid 3DTV system for ATSC terrestrial 3DTV broadcasting services. The system transmits MPEG-2 encoded left images through HD main channel (8-VSB) and H.264 encoded right images through mobile channel (M/H) simultaneously. Basically hybrid 3DTV support stereoscopic 3D HD services composed of mixed quality left/right images for 3D image rendering. For more comfortable 3D service and human factors under hybrid 3DTV service environment, we also propose new video quality enhancement technologies with small amount of disparity map information. In this paper, we propose 8-VSB & M/H hybrid 3DTV system which enables stereoscopic 3D HD, 2D HD fixed and 2D mobile broadcasting concurrently within 6MHz bandwidth, and the proposed system will provide maximum channel flexibility and extended service functionalities as well as fully backward compatibility with legacy 2D receivers.
