Abstract

MéTODO E APARELHO PARA TRANSMISSãO DE COMBINAçõES DE COMANDO POR MEIO DE CHAVEAMENTO DE DESLOCAMENTO DE FREQüêNCIA CODIFICADO. A presente invenção refere-se a um método (10) que é usado para transmissão de comandos ou combinações de comandos através de um enlace de comunicação por meio de chaveamento de deslocamento de freqüência codificado, com um comando ou combinação de comandos em cada caso sendo associado a um par de freqüências. Nesse caso, quando um comando muda de um comando ou combinação de comandos precedentes para um comando ou combinação de comandos subseqüentes, uma freqüência (que será a primeira a ser transmitida) no par de freqüências do comando ou combinação de comandos subseqüentes é escolhida como uma função de pelo menos um outro par de freqüências associado (20).
