Abstract
A technique to provide a cost effective solution to detect teletext data that can reduce detected error in teletext when the transmission data rate is known. In one example embodiment, this is accomplished by detecting data bits in an unsynchronized digital data stream by finding start of each data bit based on an estimated data bit width and transitions in the unsynchronized digital data stream.
