专利汇可以提供Voice coding/decoding transmission system专利检索,专利查询,专利分析的服务。并且PURPOSE: To code and send an input voice signal in the best state by providing plural entropy coders with different distribution of probability to plural coders and sending a code word coded by a best coder from the combined coders.
CONSTITUTION: A transmission section 1 is provided with plural coders A1-An each handles differently a quantization level number or a quantization characteristic and the quantization level number, and each of the plural coders A1-An is provided with plural entropy coders A11-Anm with different probability distribution and they are operated in parallel respectively. Then a coding characteristic code length evaluation section 3 selects a each frame of an input voice signal whose bit rate is a transmission bit rate or below so as to evaluate the quality of a local decoding signal from all coders. Thus, a code work with the bast quality is selected and a selection multiplex section 4 multiplexes the selected code word and the selection signal and sends the result to a reception side 2 via a transmission line.
