摘要：
A signal encoding method according to the present invention is a signal encoding method of dividing a coding target signal as an object of coding into partition units and performing arithmetic coding based on probability-related information in the partition units, which comprises (1) a configuration information deriving step of analyzing the coding target signal in each of the partition units to derive as configuration information, information about an initial value of the probability-related information used for the arithmetic coding of the coding target signal in the partition unit in question; (2) a coding step of performing the arithmetic coding of the coding target signal in each of the partition units, based on the configuration information derived in the configuration information deriving step; and (3) a configuration information adding step of adding a header containing the configuration information to the arithmetic-coded signal in each of the partition units.
