Abstract
Prior art methods of decoding a vertical blanking interval (VBI) scan line decoded each scan line within a given VBI using the same operational parameters, such as filter coefficients and run-in clock recovery parameters. The problem with these prior art methods is that each scan line was treated the same, even though certain scan lines within a given VBI typically exhibit different signal and content characteristics. The present invention provides for line-specific decoding of VBI scan lines. As such, each scan line within a given VBI is decoded using a set of operational parameters unique to that scan line number. These operational parameters are adjusted and maintained on a scan line by scan line basis.
