Abstract
A data slicer for extracting auxiliary video data from a video signal adapts a data slicing level to the amplitude of the data signal as indicated by the average value of a run-in clock (RIC) signal that is included in the video signal. Control of the slicing level occurs during a window interval that spans an integral number of cycles of the RIC signal. The presence of the RIC signal within the window interval may be verified as part of the slicing level adjustment operation. The data slicer is suitable for implementation in a digital integrated circuit.
