A method and an apparatus of decoding a television broadcasting signal are disclosed.
In one embodiment, an improved video decoder converts the video signal into a digitized
video signal. The improved video decoder then separates luminance information and
chrominance information of the digitized video signal in a dimension that has a
constancy value below a predetermined threshold level. Lastly, the improved video
decoder optionally converts the separated luminance information and chrominance
information into an output format that conforms to input requirements of the NTSC/PAL television.
