摘要： The present invention provides an information processor and an information processing method, which reduces the memory capacity and utilizes a free space in a memory area as a cache area for EPG. This information processor includes a program obtaining means 5, a program storage means 2 which has plural storage areas, a program execution means 13, a selection information updating means 11 that stores execution memory information indicating a storage area which contains a program to be executed by the program execution means 13, compression information which indicates compression states of programs stored in the storage areas, and memory relation information which indicates the relation of the plural storage areas, a program execution area switching means 4 for selecting one of the storage areas on the basis of the execution memory information, a storage area switching means 3 for selecting one of the storage areas on the basis of the information in the selection information updating means 11, a program writing means 6, a program compression means 7, a program restoration means 12 for restoring a program which has been compressed by the program compression means 7, and a memory information updating means 8 for updating information stored in the selection information updating means 11.

摘要： A backup unit comprises a first storage means containing at least one program and a setup file in which the operating environment of that program is written; a second storage means used when the first storage means has a fault; a duplication means for duplicating the program and the setup file contained in the first storage means, into the second storage means; and an identifier conversion means for converting identifiers included in the setup file of the first storage means and relating to the first storage means, into identifiers relating to the second storage means, when the duplication is performed. Therefore, when the operation of an information processor is stopped due to a fault in the first storage means, the second storage means enables temporary operation of the information processor. In addition, it is possible to employ, as the second storage means, a recording medium that is lower in price and writing speed than the first storage means.
