MULTIPLEX ACCESS SCHEDULING SYSTEM FOR DYNAMIC IMAGE INFORMATION

摘要

PURPOSE: To improve the use efficiency of a storage device by detecting a data amount per time required for a client and deciding the data transfer am ount of the client within a certain range so as not to make a buffer memory empty. ;CONSTITUTION: A buffer memory 12-1 temporarily stores dynamic image information and transfers data with a storage device 10 corresponding to the data transfer speed of the storage device 10. A scheduling part 19 is provided with a data transfer amount deciding means 20, and an access order deciding means 21, dynamically decides the access timing and transfer data length of the client within a certain range so as not to generate the overflow of the buffer memory at the time of data transfer to the buffer and so as not to make the buffer memory empty at the time of data transfer from the buffer memory based on the values of the data amount inside the buffer and the data amount per time to be transferred and decides the order of data transfer to the buffer of the client based on the value of responsiveness requested by the client.;COPYRIGHT: (C)1995,JPO
