Abstract

IL PROCEDIMENTO E L'APPARECCHIATURA PERMETTONO LA CODIFICA, MANIPOLAZIONE E DECODIFICA DI SEGNALI AUDIO INDIPENDENTEMENTE DAL CONTENUTO SPECIFICO DEL SEGNALE. UN CODIFICATORE (AC) EFFETTUA UNA CODIFICA PER OGGETTI E GENERA UN SEGNALE CODIFICATO, A VELOCITA' E BANDA VARIABILI, COMPRENDENTE UN LIVELLO BASE E UNO O PIU' LIVELLI DI MIGLIORAMENTO DELLA QUALITA' PER OGNI OGGETTO. IL CODIFICATORE (AC) E' IN GRADO DI OPERARE SIA SECONDO ALGORITMI AD HOC SIA CON QUALSIASI ALGORITMO STANDARD E SCEGLIE L'ALGORITMO PIU' ADATTO IN BASE ALL'OGGETTO DA CODIFICARE. UNITA' DI MANIPOLAZIONE DEL FLUSSO DI BIT LUNGO UN CANALE DI TRASMISSIONE VERSO UN CODIFICATORE (AD) PERMETTONO UNO SCALAMENTO DELLA VELOCITA' E/O DELLA LARGHEZZA DI BANDA DEL SEGNALE CODIFICATO O UN'ALTERAZIONE DEI PARAMETRI DEL SEGNALE AGENDO SUI SINGOLI OGGETTI..(FIG. 1)
