Title:
LOSSLESS DATA COMPRESSION DEVICE AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/060758
Kind Code:
A1
Abstract:
Disclosed in the present invention are a lossless data compression device and a method therefor. That is, the present invention codes symbols so that the numbers of 0s and 1s in coded data are similar on average, and performs interleaving so that 0s and 1s can be randomly distributed in the coded data, such that the interleaved code is present in a corresponding codebook and thus the probability of being compressed is increased, and the interleaved code is then compressed by using a number identifier, a location identifier, and a distinction identifier while referring to the corresponding codebook. As such, compression efficiency can be improved by compressing the coded data by using the statistical characteristics of the coded data having an average value and a deviation value.
