Abstract :
Distributed multimedia objects are concurrently manipulated by multiple transactions. We define new types of conflicting and exclusive relations on methods to serialize transactions and to realize exclusive manipulation of an object by taking into account change of QoS and state. We discuss a locking protocol for realizing mutual exclusion on objects and a scheduler for serializing transactions.
