Abstract

"DISPOSITIVO E MéTODO PARA GERAR UM SINAL DE MULTICANAIS OU UM CONJUNTO DE DADOS DE PARáMETROS". Para sinalizar de florma flexível um modo síncrono ou um modo assíncrono na reconstrução de parâmetros de multicanais, um sinal de áudio de configuração de parâmetros é inserido na corrente de dados, o qual é usado por um meio de configuração no lado de um decodificador de multicanais para configurar um meio de reconstrução de multicanais. Se o sinal de áudio de configuração de parâmetros tem um primeiro significado, os meios de configuração buscarão informação de configuração adicional em seus dados de entrada, enquanto, quando o sinal de áudio de configuração de parâmetros tem um outro significado, os meios de configuração executam uma definição de configuração dos meios de reconstrução de multicanais com base na informação sobre um algorítmo de codificação com o qual os dados do canal de transmissão foram codificados, de modo que é garantido eficientemente por um lado e flexivelmente por outro lado que sempre será obtida uma associação correta entre dados de parâmetros e dados do canal de transmissão decodificados.
