A contents distribution system uses a copyright rental use scheme in which the economical burden on the users at a time of utilizing contents can be reduced to a reasonable level, and appropriate fees can be collected for the copyrights of the contents created and provided at each stage by the raw material creators and the secondary product creators. In this system, the secondary product creator can create the secondary product contents by incorporating the raw material contents for free, and sell the secondary product contents. The end-user pays respective utilization fees to the secondary product creator and each raw material provider at a time of the purchasing the secondary product contents.

摘要:
An apparatus for supporting parallelization according to the invention is characterized by comprising a serialization unit for converting a first concurrent program having a concurrent structure into a sequential program capable of being sequentially executed, a debugging unit for debugging the sequential program and forming debugging information, and a concurrent program programming unit for performing parallelization of the debugged sequential program on the basis of the debugging information to convert the sequential program into a second concurrent program. With above configuration, the debugging unit includes a unit for introducing information associated with concurrency to the sequential program.
摘要:
A communication system comprising a communication path through which a message passes and, a plurality of communication apparatus, each apparatus includes a message transmission function to the communication path, and a read function for reading the message from the communication path. Each communication apparatus has a communication cumulative amount table so as to store the communication cumulative amount of messages transmitted by each communication apparatus as communication history data. The communication apparatus adds the latest communication cumulative amount in the communication cumulative amount table to a message which is transmitted to the communication path. The communication apparatus compares the stored communication cumulative amount table with the received communication cumulative amount. Thus, troubles of the communication subjects in the communication apparatus according to the result of the comparison can be detected. In addition, without complicated operations of each communication apparatus, while the overhead of processes is kept low, it is possible to prevent a bad effect due to a trouble or error of communication apparatus from being propagated to other communication apparatus.
