ABSTRACT:
A clocking circuit for extracting data from a video signal where the data is imbedded with other data and where the clocking rate for obtaining the data is slow as compared to the actual data rate. The circuit derives a calculated starting point for the data, using a double sample rate and a derivative to determine the beginning of the first data pulse. A clock signal is then derived which is calculated to between the leading and trailing edges of any received data pulse.
