Abstract

Un método de un aparato de recepción para recibir tramas o cuadros de transmisión. El método incluye la recepción, por los circuitos del aparato de recepción, de las tramas o cuadros de transmisión transmitidas en límites de un milisegundo. Cada una de las tramas de transmisión incluye una rutina de carga, un preámbulo y una carga útil o datos útiles. El método incluye además la determinación, por la circuitería, de un punto absoluto de tiempo en una posición predeterminada en un flujo de las tramas de transmisión en base a primera información de tiempo incluida en una primera de las tramas de transmisión.
