In this paper, the development of the prototype of 2nd generation EDTV(EDTV-II) decoder is described. We examined the system composition as the decoder for the public welfare and took the composition which used SVP(Scan-line Video Processor) for main part of the decipherment circuit. Consequently, it was possible to realize by the scale by which building into television set. In addition, a fair result was obtained about the performance because of the confirmation by the image.
