Patent ID: 11095697

Abstract:
The present disclosure discloses an Ethernet-based cascading conference phone device, which includes a master conference phone and a slave conference phone. The master conference phone receives at least one network data packet through an Ethernet, obtains a real-time stream signal according to the at least one network data packet, plays the real-time stream signal after a delay, sends the real-time stream signal to the slave conference phone, periodically sends at least one synchronized broadcast packet to the slave conference phone. The slave conference phone receives the at least one synchronized broadcast packet, receives the real-time stream signal, calculates a master-slave clock offset according to the at least one synchronized broadcast packet, performs linear compensation on the real-time stream signal according to the master-slave clock offset to obtain a compensation real-time stream signal, plays the compensation real-time stream signal and sends the real-time stream signal to the master conference phone.
