Data Encoding and Decoding Method and Device

An encoding device, comprising:

• a processor;
• and
• a storage device, storing a program code, the program code is utilized for indicating the processor to execute the following steps:
• receiving a first data with a first length;
• dividing the first data into a plurality of data segments with a first specific length;
• obtaining at least one compressible data segment composed of identical data values if it exists and at least one uncompressible data segment composed of non-identical data values if it exists from the plurality of data segments;
• compressing the at least one compressible data segment to obtain at least one compressed data segment with a second specific length if it exists;
• generating an encoding data segment according to quantity and position of the at least one compressed data segment;
• and
• combining the at least one compressed data segment, the at least one uncompressible data segment and the encoding data segment to generate a second data with a second length;
• wherein the second specific length is shorter than the first specific length.

A decoding method, comprising:

• receiving a second data with a second length;
• obtaining an encoding data segment of the second data;
• obtaining at least one compressed data segment with a second specific length if it exists and at least one uncompressible data segment with a first specific length if it exists from the second data according to the encoding data segment;
• restoring the at least one compressed data segment to at least one compressible data segment with the first specific length and identical data values if it exists;
• and
• combining the at least one compressible data segment if it exists and the at least one uncompressible data segment if it exists with the first specific length, to generate a first data with a first length;
• wherein the second specific length is shorter than the first specific length.
