The hardware implementation of a 130 Mbit/s (H4 rate) HDTV CODEC based on the DCT (discrete cosine transform) algorithm is studied for transmission in broadband ISDN (BISDN). The intrafield two-dimensional DCT, nonlinear fixed bit quantisation of eight classes with switchable operation between Y and Pr/Pb, and the four parallel signal processing possible by DCT are also implemented in the CODEC. Performance evaluation confirms that the developed CODEC has sufficient picture quality and is practical for HDTV distribution use.
