JINI FEDERATION CAPABLE OF TIME SYNCHRONIZATION USING STANDARD TIME OF DIGITAL BROADCASTING

摘要

PURPOSE: A jini federation capable of time synchronization using standard time of digital broadcasting is provided to synchronize each time information using the standard time of digital broadcasting. CONSTITUTION: A jini federation capable of time synchronization using standard time of digital broadcasting includes a plurality of resources(26), a digital television (10), a reference time detector(22), and a synchronizer(24). The plurality of resources are organically coupled by the jini federation(20). The digital television is one of the plurality of resources and receives a broadcasting signal with a predetermined program information. The reference time detector detects the reference time from the program information of the received broadcasting signal. The synchronizer synchronizes the detected reference time data and the current time data from one of the plurality of resources.
