Abstract
"MéTODO E SISTEMA PARA DETECTAR SINAIS FRACOS OU INVáLIDOS NOS FLUXOS DE DADOS". Um método é provido para detectar condições de sinal para fluxos do grupo especialista de quadro em movimento (MPEG) . Sinalizadores de modo alternado e quadros válidos dentro dos fluxos MPEG são detectados dentro de uma janela de pesquisa pré-definida. Uma indicação que um sinal válido é detectado é produzida, quando um sinalizador do modo alternado e pelo menos um quadro válido são ambos detectados dentro de uma mesma das janelas de pesquisa pré-definidas.
