It's easy for this scheme to implement in real time with existing ASIC chips and general purpose DSP chips.

In the opinion of the paper, the traditional error-bit-rate is not compitent for actually evaluating the performance of an image transmitting system. So that, a so called "Layer-cut error-bit-rate" which is competent for the evaluation of image transmitting performance is hence induced. By means of layer-cut error-bit-rate, a two-phase with multi-magnitudes modulation is analysed, and conclusions show that the modulation can construct a low-rate not compressed image transmission system with good performance. The final simulation results have" proven some of the conclusions.
