Abstract
A compression method adapts a digital format in which information representing a physical quantity is accompanied by predictable data having a value independent of that of the information representing a physical quantity. The method includes an operation of reducing the number of the predictable data, the data and information representing a physical quantity resulting from this reduction operation being able to allow the reconstitution of predictable data accompanying the information representing a physical quantity, in accordance with the digital format. Preferentially, the reduction operation includes a step of removing the predictable data, and a step of inserting substitution data, having a number less than the number of data removed during the removal step.
