ABSTRACT:
An inverse discrete cosine transform (IDCT) apparatus is disclosed. The inverse discrete cosine transform (IDCT) apparatus can satisfy the bit accuracy of the standard recommendation and enable implementation of the ASIC by a smaller logic circuit, and simplify an interface between another sections of a video decoder. According to the present invention the image recovering performance of the video decoder installed to a digital TV receiver can be enhanced.
