Embodiment 1
[0032] The information processing apparatus and information processing method of the first embodiment have two memories, and use free storage areas generated by compressing programs not currently executed among programs stored in the respective memories as cache areas for EPG.
[0033] figure 1 It is a block diagram illustrating the configuration of the information processing device according to Embodiment 1 of the present invention.
[0034] exist figure 1 Among them, the information processing device 1 is composed of a program storage unit 2, a storage area switching unit 3, a program execution area switching unit 4, a memory information storage unit 11, a program acquisition unit 5, a program writing unit 6, a program compression unit 7, and a selection information updating unit. The unit 8, the program recovery unit 12, the program execution unit 13, and the RAM 14 constitute.
[0035] Next, each configuration will be described.
[0036]The program storage unit 2 is use...

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.
Description
technical field [0001] The present invention relates to an information processing device and an information processing method, and particularly relates to an improvement of an information processing device and an information processing method for downloading a program through digital broadcasting. Background technique [0002] In recent years, with the diversification of broadcasting systems, for example, STBs, which are connected to televisions to provide various functions, are used to receive new broadcasting methods. In particular, at the same time as the start of digital broadcasting, text data for introducing programs or electronic program guide (Electronic Program Guide; hereinafter referred to as EPG) information as hypertext data is included in digital broadcasting signals and transmitted, and the STB Devices for receiving electronic program guide information and displaying them on a screen are well known. [0003] Such an information process...
