Patent

CA 2171293

A method and apparatus are disclosed for converting between samples of an input signal (104) and an encoded signal composed of a plurality of component signals each representing a characteristic of the input signal (104) in a different domain. The input signal (104) is comprised of data samples organized into records of multiple samples, with each sample occupying unique position within its record and each component signal is formed as a combination of a plurality of factors, each factor being the product of a score signal (104) and the load signal (206) defines the relative variation of a subgroup of samples in different positions of a record.

L'invention concerne un procédé et un appareil de conversion entre échantillons d'un signal d'entrée et d'un signal codé composés d'une pluralité de signaux composants représentant chacun une caractéristique du signal d'entrée dans un domaine différent. Le signal d'entrée est constitué d'échantillons de données organisés en blocs d'échantillons multiples occupant chacun une position unique dans leur bloc, et chaque signal composant correspondant à la combinaison d'une pluralité de facteurs étant chacun le produit d'un signal de repérage et d'un signal de chargement. Le signal de repérage définit les variations d'échantillons de données d'un bloc à l'autre, et le signal de charge définit la variation relative d'un sous-groupe d'échantillons à différents emplacements du bloc.
