摘要

PROBLEM TO BE SOLVED: To improve the communication efficiency.

SOLUTION: An input part 240 inputs encoding target data constituting a numeric string including a plurality of values. A storage part 2410 stores non-zero values in the encoding target data as value encoding target data, and stores the number of consecutive zero values between one non-zero value and another non-zero value as runz encoding target data. An encoder 242 encodes the runz encoding target data using a first Huffman table, and encodes the value encoding target data using a second Huffman table different from the first Huffman table. A transmission part transmits the encoding data encoded by the encoder 242.
