The metrological device, for example for a broadcasting network, for monitoring an upline broadcast signal includes a main component and upline control data. The metrological device includes an extraction circuit for extracting the upline control data from the upline broadcast signal and delivering an upline instruction, and a measuring circuit for measuring a parameter of the upline broadcast signal according to the upline instruction and delivering a measurement result. A control circuit produces a downline instruction from the measurement results and an upline result produced by the extraction circuit from the upline control data, and an insertion circuit produces a downline signal to broadcast comprising firstly the main component of the upline broadcast signal and secondly the downline control data containing the downline instruction.

The invention relates to a method of synchronizing first and second digital signals presenting digital elements to be put into correspondence, on the basis of time references. The method includes preliminary synchronization of the two digital signals using time references, by putting time references recognized as having the same value in the first and second digital signals into correspondence; and fine synchronization on the basis of a characteristic parameter obtained from the binary streams of the digital elements, and computed for each of the first and second digital signals.
