Abstract

codificação de um sinal de informação o problema do transiente pode ser suficientemente abordado, e, para esse fim, um retardo no lado de decodificação pode ser reduzido, se uma nova classe de quadro sbr for utilizada onde os limites de quadro não forem deslocados, isto é, os limites da grade ainda estão sincronizados com os limites do quadro, mas onde uma indicação de posição do transiente seja adicionalmente utilizada como um elemento de sintaxe de forma a ser utilizada, nos lados do codificador e/ou decodificador, dentro dos quadros desta nova classe de quadros para a determinação dos limites de grade dentro desses quadros.
