A highly efficient coding algorithm called extrapolative and interpolative coding which uses an adaptive intraframe/interframe prediction has been proposed for HDTV signals. In this paper, a concrete system confniguration based on this coding algorithm is studied to transmit HDTV signals at about 100Mb/s-140Mb/s. which is the H4 channel rate of broadband ISDN. High quality coding system involving coding control techniques are investigated in detail taking into account of the hardware implementation. Computer simulation results showed that the proposed method can attain high quality coding for HDTV signals at a rate of H4 channel.
