摘要
A synchronization aid device is part of receiving communication equipment of an IP network, having a primary clock signal consisting of primary clock pulses spaced apart by a first period. This device comprises i) a required to increment its value by one unit on each primary clock pulse and reset its value to zero each time it reaches a value M, ii) detection means required to generate a secondary clock pulse each time the value of the counter is zero, the secondary clock pulses forming a secondary clock signal having a second period equal to M times the first period, and iii) control means required, each time the receiving equipment receives a packet containing at least one first bit having a first value, to initialize the counter with a chosen value.
