Abstract
A method for compressing digital data, including: extrapolating a value of each sample of data to be compressed as a function of a value of at least one preceding sample, to produce an extrapolated sample; differentiating between each extrapolated sample and the corresponding sample of data to be compressed, to produce a differentiated sample; and deleting redundancy between successive differentiated samples produced by the differentiating stage.

A method for compressing digital data, comprising:
- extrapolating a value of each sample of data to be compressed as a function of a value of at least one preceding sample of data to be compressed, to produce an extrapolated sample;
- differentiating between each extrapolated sample and a corresponding sample of data to be compressed, to produce a differentiated sample;
- deleting redundancy between successive differentiated samples produced by the differentiating.
A data compression device, comprising:
- processing circuitry configured to
- extrapolate a value of each sample of data to be compressed as a function of a value of at least one preceding sample of data to be compressed, to produce an extrapolated sample;
- differentiate between each extrapolated sample and the corresponding sample of data to be compressed, to produce a differentiated sample;
- delete redundancy between successive differentiated samples.
A non-transitory computer readable medium storing a computer readable computer program comprising instructions, which when executed by a data compression device, cause the data compression device to perform a method comprising:
- extrapolating a value of each sample of data to be compressed as a function of a value of at least one preceding sample of data to be compressed, to produce an extrapolated sample;
- differentiating between each extrapolated sample and a corresponding sample of data to be compressed, to produce a differentiated sample;
- deleting redundancy between successive differentiated samples produced by the differentiating.
