<P>PROBLEM TO BE SOLVED: To easily cope with data transfer in which a real time property is requested. <P>SOLUTION: According to a control command from a bus master 10, transfer data are exchanged among applications 20 instructed by that control command via a bus 10. Each of the applications 20 has a time stamp generator and by utilizing it, the time required for exchanging the transfer data is measured. Besides, on the basis of the measured time, time management information PCR contained in the data of the MPEG2-TS standard is corrected. Thus, even the data transfer requiring the real time property can be easily coped with and especially concerning the data of the MPEG2-TS standard, data transfer can be appropriately performed. <P>COPYRIGHT: (C)2003,JPO |
