Abstract
A video decoder that separates and analyzes analog video signals includes a hue and saturation separator and a video signal determiner. The hue and saturation separator demodulates from a component video signal chroma signal, which includes a hue signal and a saturation signal. The video signal determiner determines at least one video signal characteristic of the component video signal dependent on the hue and saturation signal. The video signal determiner may include a mode determiner that determines the encoding standard of the video signal, and a color burst determiner that determines a location of a color burst signal with the video signal. The mode determiner may include a signal lock detector, a sequence matcher, and an encoding mode selector. The color burst determiner may include an absolute value determiner and a burst position determiner.
