Lossless compression of data based on a modified differential pulse code modulation (DPCM) scheme

A system for decoding data based on a biased approach, comprising:

• a processor;
• and
• a memory storing instructions that are executable by the processor to perform operations comprising:
• determining if a final output is expressed as a threshold number of bits;
• determining the final output based on a magnitude in difference between an initial sample and a previous sample in response to the final output being expressed as the threshold number of bits;
• and
• determining the final output based on a magnitude in difference between the initial sample and a predicted sample in response to the final output being expressed as a number of bits that exceed the threshold number of bits.

A non-transitory computer readable medium for decoding data based on a hybrid approach, the computer readable medium comprising a computer program that when executed by a computer, causes the computer to:

• determine a first output based on a magnitude in difference between an initial sample and a previous sample, wherein the first output includes a first number of bits;
• determine a second output based on a magnitude in difference between the first sample and a predicted sample, wherein the second output includes a second number of bits;
• compare the first output with the second output to determine if the first number of bits is greater than the second number of bits;
• and
• select one of the first output and the second output as the final output, wherein selection is based on the final output being expressed in the least number of bits.
