Method and apparatus for synchronizing digital multimedia broadcasting between terminals
First Claim
1. A method for broadcast channel synchronization by a first Mobile Station (MS) for synchronizing Digital Multimedia Broadcasting (DMB), the method comprising:
- sending a broadcast channel synchronization request message to a second MS, the broadcast channel synchronization request message including a synchronization time and period setting values;
receiving a broadcast channel synchronization request grant message from the second MS;
receiving information on a broadcast channel, from among a plurality of broadcast channels, viewed by the second MS, after the broadcast channel synchronization request grant message is received;
tuning to the broadcast channel viewed by the second MS, based on the broadcast channel information received from the second MS; and
displaying the broadcast channel viewed by the second MS.

Abstract
A method and apparatus for synchronizing Digital Multimedia Broadcasting (DMB) are provided. An operation method of a first Mobile Station (MS) for synchronizing DMB includes sending a broadcast channel synchronization request message to a second MS, receiving a broadcast channel synchronization request grant message from the second MS, after broadcast channel synchronization, receiving information on a broadcast channel viewed by the second MS, tuning to the broadcast channel viewed by the second MS based on the broadcast channel information received from the second MS, and displaying the broadcast channel viewed by the second MS.
