METHOD AND SYSTEM FOR SYNCHRONIZING OUTPUTS OF TERMINALS

摘要

PROBLEM TO BE SOLVED: To provide a method and system for group synchronization to an individual service without changing an existing network infrastructure of a provider.SOLUTION: Each terminal comprises a variable delay unit, and is connected through a low-delay communication channel to at least one synchronization unit for the purpose of calculating delay information. Further, each terminal can determine media reference information of a received media unit from the stream. The method comprising the steps of: providing one or more low-delay communication channels between the terminals and the synchronization unit; calculating delay information on the basis of synchronization information received from the terminals via the one or more low-delay communication channels, by the synchronization unit; and transmitting the delay information to at least one of the terminals to make the at least one terminal delay its output such that the outputs of the terminal group are substantially synchronized.
