Abstract

PURPOSE:To increase the efficiency of coding even to any picture, by making variable the table coding unit video information and coding the unit picture information high in the frequency of production as to the read in picture with less number of coded codes. CONSTITUTION:Picture information is read in with a reader RD, the unit picture information corresponding to picture information is outputted, and the unit picture information is converted into the code corresponding to the coder COD for sequential output. The unit picture information converted into the code with the coder COD is stored to the storage PST in the order of production so that the types of video element can be distinguished. Further, the code assignment section MDT detects the unit picture information having the maximum frequency, the optimum code is assigned and the mode information is outputted. Based on the mode information, the code system is determined at the encoder section PEC, the unit picture information is coded in the order of production and it is fed to the reception section RV via the transmission section TR. The unit picture information is decoded according to the discriminated output of the mode discrimination section MAN at the decoder PDC of the reception section RV.
