Abstract: A method and a system for media synchronization are described. The method for media synchronization may include collecting stream source information, generating network delay information between stream sources by performing a delay test between the stream sources, setting synchronization information of a stream source corresponding to a specific channel based on the collected stream source information and the network delay information, measuring network delay with at least one user terminal to receive the stream source, and updating the synchronization information based on the measured network delay.
