Abstract
Documentul de faţă se referă la o metodă de codificare stratificată a unei reprezentări de sunet comprimat a unui sunet sau a unui câmp acustic. Reprezentarea de sunet comprimat cuprinde o reprezentare de sunet comprimat de bază care cuprinde o multitudine de componente de informaţie asociată cu stratul de bază pentru decodificarea reprezentării de sunet comprimat de bază într-o reprezentare de sunet de bază reconstruită a sunetului sau câmpului acustic, şi informaţii secundare îmbunătăţite incluzând parametri pentru îmbunătăţirea reprezentării de sunet de bază reconstruite. Metoda cuprinde sub-divizarea multitudinii de componente intr-o multitudine de grupuri de componente şi atribuirea la fiecare dintre multitudinea de grupuri a unuia dintr-o multitudine de straturi ierarhice corespunzătoare, numărul de grupuri corespunzând numărului de straturi, şi multitudinea de straturi incluzând un strat de bază şi unul sau mai multe straturi de îmbunătăţire, adăugarea de informaţii secundare de bază la stratul de bază, şi determinarea unei multitudini de porţiuni de informaţii secundare de îmbunătăţire din informaţiile secundare de îmbunătăţire şi atribuirea fiecareia dintre multitudinea de porţiuni de informaţii de îmbunătăţire la unul dintre multitudinea de straturi corespunzător, în care fiecare porţiune de informaţii secundare de îmbunătăţire include parametri pentru îmbunătăţirea unei reprezentări de sunet reconstruit care poate fi obţinută din datele incluse în stratul respectiv şi orice straturi mai inferioare decât stratul respectiv. Documentul se mai referă la o metodă de decodificare a reprezentării de sunet comprimat a unui sunet sau unui câmp acustic, în care reprezentarea de sunet comprimat este codificată într-o pluralitate de starturi ierarhice care include un strat de bază şi unul sau mai multe straturi ierarhice de îmbunătăţire, precum şi la un codificator şi un decodificator pentru codificarea în straturi a reprezentării de sunet comprimat.
