A low-power sync processor chip for 3DTV shutter glasses has been proposed and implemented. The proposed sync processor adopts a newly designed floating point timer to synchronize without any sync reception and an edge tracer for universal sync-packet detection without running the CPU. The floating-point timer allows the input wireless sensor to be turned off, and the edge tracer enables the CPU to...
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...
