Metrology device for the automatic monitoring of a digital signal broadcast network and a broadcast network comprising one such metrology device
First Claim
1. A metrological device for monitoring an upline broadcast signal comprising a main component and upline control data, the metrological device comprising:
- an extraction circuit for extracting the upline control data from the upline broadcast signal and generating an upline instruction and an upline result;
a measuring circuit, to receive the upline instruction from the extraction circuit, and for measuring a parameter of the upline broadcast signal in accordance with the received upline instruction and delivering a measurement result;
a control circuit for producing a downline instruction from the measurement result and the upline result; and
an insertion circuit for producing a downline signal to broadcast including the main component of the upline broadcast signal and downline control data including the downline instruction, the downline instruction being a command to take a measurement on the downline signal.

Abstract
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.
