1. An HDTV encoder comprising:

  • a forward estimation block responsive to applied image frame pixel signals, I(t), which includesmeans, responsive to said image frame pixel signals, for developing a plurality of different types of control signals within a chosen processing time interval, T, andmeans for delaying said applied image frame signals by said chosen processing time interval to develop a delayed signal, I(t-T); and

    an encoding loop responsive to said control signals and to said delayed signal I(t-T) for developing quantized code signals for said applied image frame pixel signals.
