METHOD FOR SELECTING OPTIMAL DATA COMPRESSION METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a method for selecting one optimal data compression method out of a plurality of data compression methods for compressing source data. PSOLUTION: The method for selecting an optimal data compression method comprises a step for sampling source data (200), a step for compressing the sample data by each data compression method (250), a step for calculating the total length of the sample data compressed by each data compression method (260), a step for comparing the total lengths each other in order to determine an optimal data compression method out of a plurality of data compression methods (270), and steps for selecting an optimal data compression method (280, 290).
