摘要：A digital video signal processing apparatus and method for detecting data in avertical 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 twiceas high as the VBI data rate, a signal tracking unit tracking an existence of a clock run-inand a phase of the clock run-in from the second re-sample data and calculating anaverage of the clock run-in, and a slicer determining a logical value of the first re-sampledata according to the average of the clock run-in and outputting the determined logicalvalue as VBI data, wherein the re-sampler determines a compensation phase from thetracked phase of the clock run-in, re-samples the input video data according to thecompensation phase with the VBI data rate and generates the first re-sample data.
