摘要：
A picture coding method for coding information including picture signals of each unit,
wherein the information to be coded includes common information of the whole picture signals and information concerning the picture signals of each unit (FrmData), the picture coding method comprising:
a plural coding step for coding the common information of the whole picture signals (FrmHdr) by using a plurality of coding methods;
a common coding step for coding the information concerning the picture signals of each unit (MB, Slice) by using a variable length coding method, which is common to each unit, using a single code table or a plurality of code tables, or an arithmetic coding method; and a multiplexing step for multiplexing the coded common information of the whole picture signals and the coded information concerning the picture signals of each unit.
