摘要：
A synchronization information providing server to synchronize a broadcast program with additional information related to the broadcast program, a synchronization information providing method of synchronizing a broadcast program with additional information related to the broadcast program, a client apparatus to process synchronization information received from the synchronization information processing server and a method of processing synchronization information received from the synchronization information processing server are provided. The synchronization information providing server manages metadata of a broadcast frame constituting a broadcast program and additional information related to the metadata. The metadata includes time information and image feature information of the broadcast frame. Upon receiving synchronization request information, which includes time information and image feature information about at least one broadcast frame of a predetermined broadcast program, synchronization information to synchronize the predetermined broadcast program with additional information related to the predetermined broadcast program is provided to the client apparatus.
