Digital video signal processing apparatus and method for extracting data within Vertical Blanking Interval

The digital image signal processing apparatus and method for extracting data carried on the vertical blanking period is started. In the digital video signal processor, and from the re-sampled data rate twice the data rate of the VBI signal track portion tracking the phase of the presence of the clock run-in and run-in clock, and calculates the average of the clock run-in. Thus, applying the phase compensation is determined by the phase of the clock run-in when the re-sampling clock run-in portion to be re-samples the input image data to the VBI data rate. Slicer outputs to the value determined by determining the logical value of the re-sample data such as the VBI data rate as the VBI data based on the average value.
