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...http://www.google.fr/patents/US6377308?utm_source=gb-gplus-shareBrevet US6377308 - Method and apparatus for line-specific decoding of VBI scan lines
