Abstract :
In distributed applications, a group of multiple processes cooperate by exchanging multimedia objects with each other. The objects are decomposed into a sequence of messages, which are units of data transmission in a network. Following the causality relation among multimedia objects, we define novel types of causally precedent relations among messages decomposed from objects transmitted in a group of multiple processes. Only messages required to be causally ordered at an object level, are ordered in each process. This means that the overhead to causally deliver multimedia objects in a group can be reduced. We discuss the data transmission procedure.
