The sharing of the information processing between the electronic circuit of the ID and the external device can be widely performed from the system led by the external device in which the external device executes the OS or the like to the system led by the ID in which the electronic circuit of the ID executes the OS or the like. Combinations are possible. Therefore,
Corresponding to the division of information processing, each processing module or each step is distributed to the electronic circuit of the ID and the external device.

<Example of Starting Procedure Using ID of Information Processing System> After inserting the ID, it is automatically started (boots, system) and a menu is displayed.

2. As an example of the main menu display, a browser is used, and the menu item content is "Ne
t ”,“ HomePage ”,“ Goods ”,“ Di ”
giCam ”,“ MP3 ”, and“ Movie ”.

An example of the procedure from the insertion of the ID to the menu display will be described below with reference to the flowchart of FIG.

When the apparatus shown in FIG. 1 is turned on,
The initial control shown in the flowchart of FIG. 3 is executed when the system reset switch is pressed down or when the apparatus OS is already operating, when the ID is inserted into the drive device.

First, in step S1, it is monitored that the ID is set in the ID device 4. When the ID is set, the process proceeds to step S2, where the CPU 1 stores the ID in accordance with the minimum program stored in the ROM 2 or the device OS. The bootstrap program storage area 21 is accessed to read the bootstrap program.

In the following step S3, it is checked whether or not the bootstrap program has been read. If the bootstrap program has not been read, the program returns to step S1 again, or the CRT 6
Alternatively, an indicator (not shown) indicating “not loadable” or “digital ID” attached to the outer surface of the apparatus is lit to notify the operator (step S4).

In step S3, the reading of the bootstrap program is successful, and the set ID is the digital ID.
In step S5, a system program (for example, an operating system (OS) is included in the system program) is read using the bootstrap program just read. Thereafter, processing according to the read system program is executed.

For example, in step S6, a selection screen of an application which can be selected and executed at the present time is displayed on the CRT 6, and in step S7, a selection input is provided. , As shown in step S9,
The processing is executed according to the read application program.

FIG. 5 shows a display example of thumbnail images when "MP3" in the main menu is selected. or,
FIG. 6 shows an outline of an example of a processing procedure of the present example, and FIG. 7 is a flowchart showing an example of an operation procedure for realizing the operation of FIG.

<Example of operation procedure of information processing system>
An example of an operation procedure of the information processing system will be sequentially described with reference to FIGS. The effect of the present invention does not change even if the operation procedure is changed before and after.

First, the main menu "Net", "Ho"
“mePage”, “Goods”, “DigiCa”
One application is selected from “m”, “MP3”, and “Movie.” Here, a case where “MP3” is selected will be described as an example.

(MP3 processing) If "MP3" is selected, the process proceeds from step S11 to S12, where the music stored on this disk is provided by one network server (for music, for example, a record company). If it is music, it automatically connects to the corresponding homepage. On the other hand, when music provided by a plurality of network servers is mixed, a thumbnail display representing each network server, for example, as shown in a to j in FIG. 5, thumbnails indicating a company or an artist providing sound and music are displayed. When the user selects a desired thumbnail display from the image display, the user is connected to a corresponding homepage. At this time, a disk id (for example, a serial number different for each product sold) is transmitted to the server.

In step S21, the server waits for an access. If there is access, the process proceeds to step S23 to wait for a download request from the user.

On the other hand, the user proceeds to step S14, where the thumbnail image representing the music stored in the disk and the first part of the music are stored in the disk.
The program can be read out from the disk to display a list and preview the first part. In this case, for example, in step S14, when the user selects a desired song by clicking with a mouse, the first portion of the song is output.
The user selects whether or not to purchase, and if not, displays the thumbnail again and makes the next selection.

In the case of purchase, the process proceeds to step S15 to request download and the payment process proceeds to step S16, while the server proceeds from step S23 to S24 to set a payment method and confirm the setting. here,
The download request may send the ID of the selected song,
When the noise and the blank area are configured to be different not for each music but for each disc, a lock key may be sent.

When the payment is confirmed, the server selects a release key for releasing the lock key of the music selected in step S25, and sends it to the user together with supplementary information. Although the same release key may be used for the same music, it is preferable to use different release keys depending on the disc ID in order to eliminate injustice.

When the user receives the supplementary information with the release key from the server in step S17 via the Internet, the user releases the lock key in step S18 to restore the reproduced data by combining the incomplete data and the complementary data, and reproduces the data. A desired song can be heard from the data. Step S1
At 9 the reproduced data is stored on the disk, and thereafter this reproduced data can be used.

Thereafter, it is determined whether or not the “MP3” processing application has been terminated.
(Not shown), display the thumbnail again, and wait for the next input.

In the above example, the service information is already stored when the disc is purchased. However, the incomplete information is downloaded with the lock key after the disc is purchased, and the release key and the supplementary information of the complementary information are downloaded when the music is purchased. A configuration in which complete information can be restored only by downloading is also considered as a configuration that eliminates the waiting time for each purchase and eliminates unauthorized use.

In this embodiment, the storage medium serving as the ID has been described as a CD-RW. However, an optical disk such as a CD-R and a DVD, a magneto-optical disk, a semiconductor memory, an IC
A card such as a card, a smart card, a compact flash card or the like may be used.

Although the general-purpose computer has been described as an example of the information processing apparatus, the present invention is an invention having a feature in storage of a storage medium. It can be installed not only in mobile phones, electronic organizers, wired telephones and facsimile devices, but also in household appliances.
