| description | The invention provides a multiple-error signal coding device and a multiple-error signal coding method. The device comprises a primary error signal coder and a multiple-error signal coder array, wherein the primary error signal coder simultaneously receives P channel data streams for performing primary error signal coding processing so as to generate a primary error signal coding data stream; and the multiple-error signal coder array comprises Q series-connected multiple-error signal coders and is used for performing Q times of parallel subtraction coding processing on the primary error signal coding data stream so as to generate (R-1) channel multiple-error signal coding data streams. By using the characteristic that bit width of hardware limits overflow, and a mechanism which is shared by symbols of software, the number of the symbols which is subjected to the error signal coding is the same as that of the original input data, so that the symbol length and the average coding length which are generated by ba |
