METROLOGY DEVICE FOR THE AUTOMATIC MONITORING OF A DIGITAL SIGNAL BROADCAST NETWORK AND A BROADCAST NETWORK COMPRISING ONE SUCH METROLOGY DEVICE

摘要

The invention relates to a metrology device (200) which is used to monitor an upstream broadcast signal comprising one main component and upstream control data. The inventive metrology device (200) comprises: a recovery circuit (220) which is used to recover the upstream control data from the upstream broadcast signal and to supply an upstream instruction; and a measuring circuit (230) which is used to measure a parameter of the upstream broadcast signal in accordance with the upstream instruction and to supply a measurement result. According to the invention, the metrology device (200) also comprises: - a control circuit (250) which is used to produce a downstream instruction from the measurement result and from an upstream result which is produced by the recovery circuit (220) using the upstream control data; - an insertion circuit (240) which is used to produce a signal to be broadcast downstream comprising (i) the main component of the upstream broadcast signal and (ii) downstream control data comprising the downstream instruction. The invention also relates to a broadcast network using one such metrology device.
