Abstract

SISTEMA E MéTODO PARA DETECçãO DE FORMATO DE TRANSMISSãO". Um sistema e um método para detectar um formato correto de transmissão ao se encontrar um erro de decodificação em um esquema de transmissão de formato variável, em que o erro de decodificação resulta de uma decodificação mal sucedida de um frame. A invenção possibilita a priorização dos formatos permissíveis, resultando em uma ordem priorizada. Os dados de frame são a seguir decodificados de acordo com um ou mais dentre os formatos permissíveis na ordem priorizada e, caso a decodificação seja bem sucedida de acordo com um dos formatos, tal formato é selecionado como o formato correto de transmissão.
