An object of the present invention is to achieve an efficient and low-cost processing for switching contents on a display according to travel areas, time frames and vehicle attributions of a transportation object. To this end, the present invention provides a system constituted of a content delivery server and the e-paper. The content delivery server includes: an designation receiving unit for storing schedule designation information in a database of content/schedule information; a transportation object specification unit for specifying a transportation object according to attribute information of an e-paper; a travel schedule specification unit for specifying information on a scheduled travel time in an display area; an interval-period computing unit for associating a display period of content with a display area; a travel area specification unit for storing information on a travel area corresponding to the display area; a content setting unit for associating the information on the travel area with attribute information of the content; and a delivery processing unit for transmitting, to the e-paper, display schedule information and the content. The e-paper includes: a data obtaining unit for obtaining contents and display schedule information from the content delivery server; and a display processing unit for switching the contents to be output on a display panel according to the display schedule of the contents.

Content display control method and content delivery server

A semiconductor file system features a first nonvolatile memory electrically erasable, a second nonvolatile memory not electrically erasable, a volatile memory, a controller, and a control section which controls the controller wherein a physical address corresponding to a logical address specified from an external system is accessed. The first nonvolatile memory stores data for the external system to perform operations, first management information indicating correspondence between physical and logical addresses, and second management information indicating a state of the first nonvolatile memory. The second nonvolatile memory previously stores interface information. The controller determines a physical sector address. The control section is for controlling input/output of data from/to the external system and for temporarily storing write data into the first nonvolatile memory from the external system in the volatile memory and then transferring the write data from the volatile memory to the first nonvolatile memory.

Flash memory control method and apparatus processing system therewith

A control method and system when a flash memory is used. as a semiconductor disk or a main memory in an information processing system. A semiconductor file system comprises a first nonvolatile memory electrically erasable, a second nonvolatile memory not electrically erasable, a volatile memory, a controller which controls the memories, and a control section which controls the controller wherein a physical address corresponding to a logical address specified from an external system is accessed. The first nonvolatile memory stores data for the external system to perform operations, first management information indicating the correspondence between physical addresses at which the data is stored and logical addresses, and second management information indicating a state of the first nonvolatile memory. The second nonvolatile memory previously stores interface information required for inputting and outputting the data from and to the external system and read-only data of the data. The controller comprises control means for determining a physical sector address forming predetermined high-order bits of the physical address when data is output from the first nonvolatile memory or when data is input to the volatile memory, means for storing the determined physical sector address, and means for consecutively generating addresses in a sector determined by the physical sector address. The control section is responsive to the interface information, the first management information, and the second management information for controlling input/output of data from/to the external system and for temporarily storing write data into the first nonvolatile memory from the external system in the volatile memory and then transferring the write data from the volatile memory to the first nonvolatile memory. The consecutive address generation means and the sector address storage means output the physical sector address and the consecutively generated addresses to the first nonvolatile memory and the volatile memory when data at the physical sector address is output from the first nonvolatile memory or when data at the physical sector address is input to the volatile memory.
