Prospects for cost effective VLSI implementation of HDTV codecs

The key functional modules in an HDTV codec are motion estimator, 2-D DCT/IDCT, and variable-length coder and decoder. The state-of-the-art VLSI implementation techniques for these key modules will be presented. For HDTV applications, these implementations are pointing towards cost effective design. Based on these, reasonable cost HDTV codecs can be realized by using powerful CAD tools as well as advanced VLSI technology
