In a normal operation state, a connection management section writes data transmitted from a first processing section to a data temporary storage section and reads data to be received by a second processing section from the data temporary storage section. Upon receiving control signals which instruct a change of the subject of processing, the first processing section and the second processing section output a transmitting-end clear request and a receiving-end clear request, respectively. The connection management section reads data from the empty data storage section after a transmitting-end clear request is received and until a receiving-end clear request is received, and writes data to the empty data storage section after a receiving-end clear request is received and until a transmitting-end clear request is received.

Conventionally, when a multimedia data processing section that has become a component is taken out of a database, it is necessary that the multimedia data processing section is taken out of the database once and a condition determination of this multimedia data processing section and other multimedia data processing sections is performed, and the problem is that a search for a multimedia data processing section is thus time consuming. According to the present invention, not only the body of a multimedia data processing section (), but also a function entry () of a function () that performs a condition determination of the multimedia data processing section () is registered with a database (), so that when a search for the multimedia data processing section () is performed, the function entry alone is taken out first and a condition determination is performed, and, only when it suits the purpose, the body of the multimedia data processing section () is taken out. By this means, search time for the multimedia data processing section () can be reduced.
