Method of detecting a format type of an incoming video signal and source format detector thereof
A source format detector for detecting a format of a video signal includes a frequency data generator for generating first frequency data corresponding to a first field in the video signal, and second frequency data corresponding to a second field in the video signal; a transform domain comparator for comparing the first frequency data with the second frequency data to thereby obtain a comparison result; and a detector for detecting the format of the video signal according to comparison results for a plurality of first and second fields.
