Abstract

Se proporcionan un método y aparato para recuperar campos de localización de paquete de audio y/o información de límite de la trama a partir de una trama de señal de radio difusión digital recibida en el cual se detectan errores en el encabezamiento de la trama de señal por usar elementos de encabezamiento seleccionados y/o parámetros de bloque de datos estructurados de unidad de datos de protocolo (PDU) con relación a longitud de paquete mínimo, máximo y promedio o longitud PDU en un proceso de recuperación escalable que puede ser acelerado dinámicamente o configurado estáticamente en base a las fuentes de computación disponibles dentro de una implementación específica y/o un tiempo específico.
