Abstract
Transmisor (40) para transmitir una secuencia intermitente (500) de mensajes (512, 514, 516, 522, 524, 526), cada uno de los cuales es capaz de sincronizar un reloj de un receptor con un reloj del transmisor, en el que dichos mensajes secuenciales se presentan en grupos (510, 520), estando separado cada grupo (510) del siguiente grupo (520) por un primer periodo de tiempo (T1) y comprendiendo una pluralidad de mensajes en serie (512, 514, 516, 522, 524, 526), estando separado cada uno de la pluralidad de mensajes de un grupo de un mensaje adyacente de este grupo por un segundo periodo de tiempo (t), que comprende: medios de transmisión (44) para transmitir cada uno de dichos mensajes secuenciales; y medios de control (60) dispuestos para proporcionar, cuando existe una variación de la secuencia de mensajes, información de control para transmisión de al menos un mensaje secuencial, informando al menos a un receptor de una variación de la secuencia de mensajes, manteniendo por ello, después de la variación, la sincronización del reloj del receptor con el reloj del transmisor, incluyendo la información de control parámetros para informar de una variación de alguno o varios entre los siguientes elementos el primer periodo de tiempo (T1), el segundo periodo de tiempo (t) y el número (N) de mensajes de un grupo.
