In distributed applications, a group of multiple processes are cooperating 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 the overhead to causally deliver multimedia objects in a group can be reduced. We discuss the data transmission procedure.
