Abstract
A digital video signal processing apparatus and method for detecting data in a vertical blanking interval (VBI) includes a re-sampler generating, from input video data, first re-sample data at a VBI data rate and second re-sample data with a data rate twice as high as the VBI data rate, a signal tracking unit tracking an existence of a clock run-in and a phase of the clock run-in from the second re-sample data and calculating an average of the clock run-in, and a slicer determining a logical value of the first re-sample data according to the average of the clock run-in and outputting the determined logical value as VBI data, wherein the re-sampler determines a compensation phase from the tracked phase of the clock run-in, re-samples the input video data according to the compensation phase with the VBI data rate and generates the first re-sample data.
