Abstract :
A noise robust sync processor chip for 3DTV shutter glasses is proposed and implemented. The existing 3DTV shutter glasses have to receive the sync pulse continuously from the 3DTV to synchronize between two independently-clocked systems. These sync packets are easily interfered by the noise of fluorescent light and the existing TV remote controller signal. Especially the 3DTV users easily suffer from the flicker effect by the synchronization loss. The proposed sync processor adopts the CRC protection for the non-valid sync packet, frame indexing for the valid signal, and newly designed timer to synchronize without any sync signal reception for about one hour to achieve perfect noise robustness. The 3DTV shutter glasses controller including the proposed sync processor is fabricated in 0.18um CMOS technology, has a die size of 2.4mm × 2.3mm.
