In this paper, we apply a stream-oriented database processing scheme for the continues media data processing. We focus on the presentation operations for the continues media data. In this kind of processing, database operations are repeatedly executed. For example, in the case that several music data streams are presented simultaneously, as that, stream-A and stream-B are presented as the background music, stream-C is presented as the main melody music. It is clear that when the vackground music is repeated, the detabase operation for processing the background music must be repeatedly executed. It is shown in this paper that the overhead of the re-execution can be reduced by optimal memory resources allocation. Therefore, we introduce an optimal memory allocation method. A heuristics is utilized in the method. Based on the heuristics, the calculation complexity of the method is reduced. We also discuss the property of the method and show several calculation examples to clarify the efficiency of the method.
