发明名称 Data network with time synchronization mechanism
摘要 <p>The invention relates to a method and a system for matching frame counter values of a timing master and at least one slave in a synchronous network having a ring topology, and a computer-readable medium. To reliably and quickly detect a synchronization loss within the synchronous network, a timing master counts transmitted frames of a continuous data stream. In the event of a synchronization loss, the timing master transmits a message to all slaves including a synchronization frame counter value so as to synchronize the frame counter value of the timing master and the frame counter value of the slaves to a common frame counter value. Therewith, resynchronization of the network is possible in short time. Also, a synchronous playback of audio/video data on a plurality of terminals attached to the network is possible due to applications running on the slaves having access to the respective frame counter value of the respective slave.</p>
