Title
(EN) HAND-HELD AUDIO DECODER
(FR) DÉCODEUR AUDIO PORTATIF
Abstract
(EN) A hand-held audio decoder including a central processing unit operating in response to a set of instructions for decoding a stream of encoded digital audio data. The audio decoder also includes memory for storing the set of instructions and digital to analog converter circuitry for generating audio from the decoded stream of digital audio data.
(FR) L'invention concerne un décodeur audio portatif qui comprend une unité de traitement centrale réagissant à un ensemble d'instructions pour décoder un flux de données audio numériques codées. Le décodeur audio comprend également une mémoire pour stocker l'ensemble d'instructions et des circuits de conversion analogique-numérique permettant de générer des données audio à partir du flux décodé de données numériques audio.
