    Abstract: A digital signal processing system and method applied for chroma transition, wherein the method has the acts of: performing a difference process on an original chroma signal C to obtain a first difference signal C'; calculating an absolute value |C'| of the first difference signal C'; performing a difference process on the absolute value |C'| to obtain a second difference signal Ca'; determining whether the second difference signal Ca' is a positive signal or a negative signal; wherein based on a determined result, an optimized chroma signal is generated by either mixing the original input chroma signal C with a k-delayed chroma signal, or mixing the k-delayed chroma signal C[n-k] with a 2k-delayed chroma signal C[n-2k], where k is a constant.
