A METHOD AND SYSTEM FOR LOSSLESS AND ADAPTIVE DATA COMPRESSION AND DECOMPRESSION Abstract of the Disclosure The invention provides a method and system for compressing and decompressing data in real-time in which compressed data uses significantly less memory than the raw data. The system compresses data by calculating the differences between adjacent data values, identifying a plurality of frequently occurring differences, tracking the frequency of occurrence of the identified differences, generating a first encoding for the identified differences, wherein the length of the encoding is based on the fre- quency of occurrence, generating a second encoding for the differences other than the identified differences, and for each calculated difference, encoding the calculated differ- ence using the first encoding when the calculated differ- ence is an identified difference and encoding the calcu- lated difference using the second encoding when the calcu- lated difference is not an identified difference to effect the compression of the data.
