The signal can be output to an external device.

In addition, as shown in FIG. 4, a hole 10 for accommodating the battery 11 is formed in the bottom of the main body 1. This hole 10 is closed by the battery 11 when the battery 11 is accommodated. The battery 11 is housed in the hole 10 and can be released and detached by sliding the slide button 12 to the left in FIG.

5 and 6 show the external configuration of the outer lid 3 with the main body 1 open. As shown in FIG. 5, when the outer lid 3 is rotated with respect to the main body 1, the intermediate lid 2 is exposed. On the upper surface of the middle lid 2, a keyboard having various operation buttons 19 is formed. This operation button 19 is shown in detail in FIG. The upper left side of the middle lid 2 is provided with a power button 20 for turning on or off the power. When the power is turned on by operating the power button 20, the power lamp 21 provided on the upper left side of the main body 1 is turned on. The power lamp 21 turns off when the power is turned off. Moreover, this power supply lamp 21 blinks when the voltage of the battery 11 falls below a predetermined reference value in a state where the battery 11 is operated by the battery 11 without supplying a DC power supply from the jack 8. The power lamp 21 is arranged so that the lighting state can be observed even in the closed state as well as in the closed state of the outer lid 3.

Five function keys (Fl to F5) 22 are provided on the right side of the power button 20, and a corresponding operation is performed when any of them are operated. On the center left side of the middle lid 2, a letter key 23 for inputting alphabetic characters is arranged. On the lower side, a shift key 24, a character key 25, a space key 26, and a back space 27 are provided. The shift key 24 is operated simultaneously with the letter key 23, for example, when inputting uppercase alphabetic characters. The space key 26 is operated when inserting a space. The backspace key 27 is operated when the display unit 31 described later deletes the characters displayed on the left side of the console. The character key 25 is operated simultaneously with the character key 23, for example, when inputting a character having an umlaut in German or the like.

On the right side of the character key 23, a ten key 29 which is operated when a number is input is provided. Further, a special key (SP key) 28 is provided above the ten key 29. The SP key 28 is operated when the change program is operated, for example, when the input mode is changed into any one of the English input mode, the German input mode, the French input mode, or when the time of auto power off is selected and changed.

The operation board 41 in which the arrows 42-45 are shown up, down, left and right is provided under the tenkey 29. As shown in FIG. The display position of the console can be moved up, down, left, and right by pressing the portion indicated by the arrows 42 to 45 of the operation panel 41. An approximately straight protrusion 51 is formed on the left side of the operation panel 41, and a NO key 53 is provided on the upper side of the protrusion 51 and a YES key 52 on the lower side, respectively. For example, by placing the index finger on the protruding portion 51, the thumb on the YES key 52, and the middle finger on the NO key 53, the keys can be reliably operated without seeing these keys. The YES key 52 has a convex surface on the YES key 52 so that the YES key 52 and the NO key 53 can be distinguished only by touching with a fingertip. It is formed in concave shape.

The YES key 52 and the NO key 53 are operated when inputting a positive response or a negative response, respectively. These correspond to the ENTER key and the escape key ESC (not shown) in the personal computer, respectively, and are assigned the same key code (ODH or IBH).

On the inner surface of the outer lid 3, a display portion 31 consisting of an LCD 100 (see FIG. 9) of 320 x 200 dots is formed at an approximately center position, and images or characters reproduced from the CD-ROM 66 are formed thereon. By operating the key 23 and the ten key 29, input characters, numbers, and the like are displayed. On the right side of the display portion 31, a knob 32 is provided, and when the contrast of the display portion 31 is adjusted, the knob 32 is operated in a clockwise or counterclockwise direction. A slide button 33 is formed below the tongs 32, and when the backlight (not shown) disposed inside the display portion 31 (rear side of the LCD 100) is turned on or off in FIG. It slides down.

A sound discharge portion 34 is provided on the side facing the main body 1 (middle lid 2) at the engaging portion 35 (lower portion of the display portion 31) of the outer lid 3 with the main body 1. The speaker 37 is arrange | positioned inside. The speaker 37 (soundproof part 34) is disposed in the same plane as the display part 31, and is oriented in the same direction as the display part 31. Therefore, compared to the case where the speaker 37 is disposed on the side of the outer lid 3, for example, a user who uses the apparatus while viewing the display unit 31 can more easily hear the sound output from the speaker 37.

Moreover, the hook 36 is formed in the front-end | tip part (upper side of FIG. 6) of the inner surface of the outer lid 3, and is locked by the lock part 55 of the main body 1 when the outer lid 3 is closed.

7 and 8 illustrate a state in which the intermediate lid 2 is opened. 7 shows a state in which the middle lid 2 is opened, and FIG. 8 shows a state in which the outer lid 3 and the middle lid 2 are removed from the main body 1, respectively.

As shown in FIG. 7, when the outer lid 3 is rotated with respect to the main body 1, and the center lid 2 is also rotated with respect to the main body 1 and all of them are opened, the upper lid 3 The mounting portion 60 of the formed CD-ROM 66 is exposed. The turntable 61 is arrange | positioned at the center of this mounting part 60, and the chuck | zipper part 62 is formed in the center. When the CD-ROM 66 is played back, the CD-ROM 66 is chucked by the chuck 62 when the CD-ROM 66 is placed on the turntable 61. This prevents the CD-ROM 66 from being separated from the turntable 61 even when the turntable 61 is rotated at a high speed. The outer periphery of the turntable 61 is formed with a recess 65 of a size roughly corresponding to the CD-ROM 66 and the CD-ROM 66 can rotate without contacting the main body 1. have. Moreover, the recessed part 64 is formed in communication with this recessed part 65, and extended to the outer side. By attaching a finger to the recess, the CD-ROM 66 can be easily attached to and detached from the turntable 61.

As shown in FIG. 8, an optical pickup 71 is arranged inside the main body 1 so as to be movable in the direction indicated by arrow A in the figure (radial direction of the CD-ROM). For this reason, a thread motor (not shown) for transferring the optical pickup 71 in the radial direction of the CD-ROM 66 is housed inside the main body 1. In addition, the optical pickup 71 has a focus actuator and a tracking actuator (both not shown) and a servo is applied in the focus direction and the tracking direction.

9 shows the configuration of a circuit built in the main body 1. As shown in FIG. The key matrix 81 detects the operation of the operation button 19 of the middle lid 2 and outputs the detection signal to the keyboard controller 82 which is a one-chip microcomputer. The keyboard controller 82 operates at a clock of 6 MHz and outputs a signal corresponding to the operation of the operation button 19 to the core chip 83. The core chip 83 executes processing for making the program and data supplied from the CD-ROM 66 compatible with the personal computer PC / XT (trademark of IBM company) of the IBM company. The core chip 83 is connected to a main CPU (V20HL manufactured by NEC) 84 that controls each part. The CPU 84 operating at a clock of 9.54545 MHz is connected to the program ROM 86, the EEPROM 87, and the drive controller 88 via an interface LSI 85 operating at a clock of 28.63636 MHz.

The program ROM 86 stores a program necessary for the CPU 84 to operate. This program includes, in addition to the system program, a change program executed when the SP key 28 is operated, a program for ensuring data compatibility between different versions of playback devices (programs), and a program (PIEX described later). have. The EEPROM 87 frequently stores data that needs to be retained even after the power is turned off. The drive controller 88 is connected to the pickup drive unit 89 and is provided with a CD-ROM (supplyed from the pickup drive unit 89). The demodulated playback data from 66 is output, and the audio signal therein is output to the speaker 37 and the jack 4 (FIG. 2), and the video data is output to the interface LSI 85.

The interface LSI 85 is also interconnected via a bus with the core chip 83, DRAM 91 as main memory, universal asynchronous receiver / transmitter 92, and LCD / CRT controller 94, It is possible to send and receive. The DRAM 91 stores data supplied from the core chip 83, the interface LSI 85, the UART 92, the LCD / CRT controller 94, etc. as needed. The UART 92 performs a process necessary for generating data conforming to the RS232C standard and outputs it to the driver receiver 93. The output of the driver receiver 93 is output to the plug 7 (FIG. 2). In addition, data of RS232C input from the plug 7 is voltage-converted in the driver receiver 93 and input to the UART 92. The UART 92 converts the input data into data that the CPU 84 can process.

The LCD / CRT controller 94 controls the operation related to the display. That is, the controller 94 causes the video signal output to the LCD 100 or the video output terminal 9 to be written to the DRAM 97 via the interface LSI 95. This DRAM 97 is a video RAM and bitmap data corresponding to the display screen is developed. The interface LSI 95 has a built-in ROM 96 and stores therein data used for converting the gradation or color of a display image. The converter 98 converts the digital RGB for the computer output from the interface LSI 195 into an analog video signal of the NTSC system and outputs it to the video output terminal 9. The driver 99 also supplies and displays the monochrome video data output from the interface LSI 95 to the LCD 100. The driver 99 also controls the contrast of the LCD 100 and the on / off control of the backlight EL light in response to the operation of the tong part 32 and the slide buttons 33 (FIGS. 5 and 6). The LCD 100 is provided in the above-described display unit 31 together with the backlight.

Next, the operation of the embodiment of FIG. 9 will be described. When the operation button 19 (FIG. 6) is operated, the operated key is detected by the key matrix 81 and the detection signal is input to the CPU 84 via the keyboard controller 82 and the core chip 83. do. The CPU 84 executes a process corresponding to a command (command) from this operated key depending on the program stored in the program ROM 86 or the DRAM 91.

For example, if playback of the CD-ROM 66 is commanded now, the CPU 84 controls the drive controller 88 via the interface LSI 85 and drives the pickup drive unit 89. The pickup drive unit 89 drives the optical pickup 71 (FIG. 8) and reproduces the information recorded on the CD-ROM 66. As shown in FIG. The drive controller 88 demodulates the signal supplied from the pickup drive unit 89. Since the audio data of the CD-ROM 66 is compressed in its time axis, the drive controller 88 extends the time axis and outputs it to the jack 4 and the speaker 37. In this way, the audio signal reproduced from the CD-ROM 66 can be heard by the headphones connected to the speaker 37 or the jack 4. The volume at this time can be adjusted by operating the volume buttons 5 (FIGS. 2 and 5). In addition, when a headphone is connected to the jack 4, the supply of the audio signal to the speaker 37 is stopped and the audio signal is output only to the headphones.

When the audio signal is reproduced by the speaker 37, the air at the front of the speaker 37 (outside of the outer lid 3) vibrates and air to the inside of the outer lid 3 housing the speaker 37. Vibrate. In the state in which the outer lid 3 is open, the air vibration generated outside the outer lid 3 is diverged into the open space and thus has little effect on the air vibration inside the main body 1. In addition, since the outer lid 3 has a configuration independent of the main body 1, there is no fear that the air vibration of the outer lid 3 is transmitted as air vibrations inside the main body 1, and is accommodated in the main body 1. The possibility that the servo by the focus actuator, the tracking actuator, the thread motor, or the like for driving the optical pickup 71 which is present may malfunction due to air vibration from the speaker 37 is suppressed.

On the other hand, the video data reproduced from the CD-ROM 66 is output from the drive controller 88 and once written to the DRAM 91 via the interface LSI 85. This data is processed by the core chip 83 as necessary to maintain compatibility with data of the personal computer PC / XT of IBM Corporation. The CPU 84 supplies and stores video data to the DRAM 97 via the LCD / CRT controller 94 and the interface LSI 95. The video data developed in the DRAM 97 is read by the controller 94 via the interface LSI 95 and output and displayed on the LCD 100 (display section 31) via the driver 99. In this case, when the change of the gray level is instructed, the controller 94 controls the interface LSI 95 and converts the gray level of the pixel data according to the table stored in the ROM 96 to output it. This gradation control is performed by controlling the number of light emission (light shielding) times for each pixel per unit time of the LCD 100.

When a CRT or the like is connected to the video output terminal 9, the controller 94 controls the driver 99 via the interface LSI 95, turns off the backlight of the LCD 100, and stops displaying the image. The video data read from the DRAM 97 is converted into an NTSC video signal by the converter 98 and output to the video output terminal 9. As a result, the image based on the video data read out from the CD-ROM 66 can be monitored via the NTSC CRT. At this time, the output of the audio signal from the jack 4 or the speaker 37 is continued as it is.

The video data reproduced from the CD-ROM 66 is 8 bits, and the upper 3 bits, the next upper 3 bits, and the lower 2 bits are allocated as data of R, G, and B, respectively, and represent 256 kinds of colors. It is possible. The color circuit 101 of the interface LPI 95 calculates the logical sum of two bits of data allocated to B, adds the obtained data to the lower part of the two bits of data, and converts the data of B into three bits of data. A total of 9 bits of video data in which each of R, G, and B are allocated to 3 bits is output to the converter 98.

When the interface LSI 95 has the color lookup table CLUT described later, a RAM 102 as a CLUT is provided in place of the color circuit 101. In this case, the interface LSI 95 stores 8 bits of data read from the DRAM 97 and 18 bits of data (R, G, and B, 6 bits of data) or 24 bits of data (R, G, and B). Eight bits of data) or 24 bits of data (R, G, and B are eight bits of data, respectively) are outputted to the converter 98.

Audio data, video data, text data and the like are converted into RS232C data by the UART 92 and output from the plug 7 via the driver receiver 93 as needed.

Next, a description will be given again with reference to FIG. 10 regarding the interrelationship between models having different functions that are the premise of the present system. 10 shows changes in the model. That is, the successor device P1 is first developed, and then the successor device P2 is developed which adds a new function to the preceding device P1, and then the device P3 is developed as a successor model of the device P2. Shall be.

For example, device P1 has 256 bytes of EEPROM (nonvolatile memory) 87 at 9 degrees, but device P2 does not have this EEPROM and instead has a 32 megabyte fixed disk ( It is assumed that a hard disk drive (HDD) 111 is included.

In each device P1, P2, P3, dedicated expansion device drivers (matching programs PIEX1, PIEX2, PIEX3) are stored in the internal program ROM 86, respectively. PIEX1, PIEX2, and PIEX3 are set in advance with information on matters that need matching (to be described later) in order to ensure compatibility with other models.

11 shows an example of the configuration of a program stored in the program ROM 86 of the devices P1 to P3. In this embodiment, BIOS and DOS are employed as the system program. As this DOS, ROM-DOS of MS-DOS (a trademark of Microsoft Corporation) is adopted. In addition, MSCDEX, which functions as an interface between CD-ROMXA and MS-DOS, is used to drive an XA-compliant CD-ROM. In addition, a CD player, which is a program for playing a normal music CD (CD-DA), is prepared. SHELL.COM is a program for determining different types of CDs, as described below. In addition, proportional fonts, device drivers, and various files are also stored in the program ROM 86.

In addition, PIEX is prepared that the versions are different for each of the devices (P1 to P3).

The CPU 84 has various registers as shown in FIG. 12 to execute the processing of various programs. General purpose registers consist of AX, DX, CX, BX, BP, SI, DI, and SP, each with 16 bits of capacity. AX, DX, CX, and BX are divided into AH, AL, DH, DL, CH, CL, BH, and BL of the registers of the upper 8 and lower 8 bits, respectively. As segment registers, CS, DS, SS, and ES are prepared, and they can store 16 bits of data. In addition, 16 bits of F and IP are prepared as status control registers.

In this system, files of EXEME.EXE or EXEME.COM are necessarily prepared in an application program executed by each device P1, P2, P3, that is, a CD-ROM that can be played back on these devices. By the EXEME.EXE or EXEME.COM, the above-described PIEX initialization process is started, and matching between the heterogeneous models of the preceding and succeeding models, the lower models and the upper models is made.

Next, the structural example of PIEX etc. is demonstrated. PIEX consists of the following 10 blocks.

Next, the content of each block mentioned above is demonstrated.

(1) Service 00h: Version / Peripheral

This block consists of the following six subservices:

This subservice is to obtain the ID of the device main body. In addition to the ID (machine ID) of the apparatus main body, this ID includes versions of each PIEX (for example, PIEX1, PIEX2, and PIEX3 in FIG. 10). When the service number of 00h and the subservice number of 00h are set in registers AH and AL of the CPU 84, machine ID numbers, PIEX version numbers, and player or emulator information are output to AX, BX, and CX, respectively. This processing is described as follows.

Subservice 01h: Get Peripheral Information

Subservice 03h: Check If Application Runs Normally

IDs are assigned to all application programs available in the apparatus. From this ID, it is determined whether or not the application program can be used. To confirm this, service number 00h and subservice number 03h are set in registers AH and AL, and an application ID is input in registers BX and CX, and 0 or other information is output in register AX. "0" indicates that the application program operates normally, and the other indicates that the application program does not operate normally.

Subservice 04h: Initialize PIEX Environment

This is a subservice that initializes the system. When the service number 00h and subservice number 04h are set in registers AH and AL, an initialization operation is performed. When the initialization operation is performed normally, "0" is set in the register AX and "other" is set when an error occurs.

Subservice 05h: Terminate PIEX

This processing returns the system to the state before initialization. If service number 00h and service number 05h are set in registers AH and AL, a process is performed in which the system returns to the state before initialization, and 0 is set in register AX when the processing is normal, and other values when an error occurs. Is set.

That is, when the service number 01h and the subservice number 00h are set in the registers AH and AL, and 0 or 1 is set in the BL register, the color mode display or the monochrome mode display is performed. When such a setting is made, the CPU 84 controls the controller 94 and executes color display or black and white display corresponding to the set data.

Subservice 01h: Get Color Mode

This service is for getting information whether the current output is color or black and white. That is, if service number 01h and subservice number 01h are set in registers AH and AL, 0 is output in register BL when the current mode is color mode, and 1 is output in monochrome mode.

Subservice 02h: Set LCD 7 Gray Scale Conversion Table

In this embodiment, since the LCD 100 is capable of monochrome display only, conversion of the ROM 96 that determines which of the seven gray levels is converted when supplying the color video data of R, G, and B to the LCD 100. Is to select a table. Four types are prepared as this conversion table, for example, and any one of them is selected. In other words, if the service number and subservice number corresponding to the registers AH and AL are inputted, and the predetermined value is inputted to the register BL again, the specified one of the four types of tables is used. When the value set in the register BL is 0, it is selected for the normal table, and when the value is set for 1,2 or 3, the table for setting the weak, medium, or strong gray level is selected.

Subservice 03h: Get LCD Conversion Table

This service is for obtaining the number of the gradation tape currently selected. If this service is specified, the type of table currently selected in the register BL is output.

(3) Service 02h Proportional Font Manager

Subservice 00h: Select Font

This is a subservice for font selection. If this service is specified in registers AH and AL, and the font number is specified in register BL again, and the address of the font registered by the user in registers ES and DI, the CPU 84 processes to use the specified font. Perform When this process is performed normally, 0 is output to the register AX, and a value of 1 or 2 is output when there is an error in the system font number or an error in the user registered font data, respectively.

Subservice 01h: Get Current Font

This service gets the current font number. Specifying this service in registers AH and AL prints the font number in register BL and the height of the font in register BH. The register CL outputs the upcent of the font (the height from the baseline of the character (for example, the character q) displayed by protruding downward relative to the predetermined baseline), and the address of the user registered font and the user in the registers ES and DI. The address of the registered font name is output.

Subservice 02h: Set Virtual Screen Address

This service is to set the address of the output screen. Registers AH and AL specify the service, and registers ES and DI address the virtual screen. At this time, the CPU 84 sets the address of the output screen to the designated screen.

Subservice 03h: Get Virtual Address

This is to get the address of the current output screen. If this service is specified in registers AH and AL, the virtual address is output to registers ES and DI.

Subservice 04h: Set display Color

This service selects the color and specifies the service in registers AH and AL, and the foreground and background colors in registers CX and BX.

Subservice 05h: Get Display Color

This service gets the color of the current output. If this service is specified by registers AH and AL, the foreground and background values are printed in registers CX and BX respectively.

Subservice 06h: Set Display Attributes

(4) Service 03h: Reserved

This service is reserved for new features.

(5) Service 04h: Scratch Pad Memory

This service is a service relating to the EEPROM 87. In this service, EEPROM 87 is used as shown in FIG. That is, 10 bytes of the 256-byte capacity are used for the system, and the remaining 246 bytes are used for the application. The 246-byte area used for applications is divided into six partitions (blocks) of 41 bytes each. Since each partition (block) can correspond to one application (each CD-ROM 66), it becomes possible to manage a total of six applications (six CD-ROMs).

Each partition (block) has the following structure.

The Application ID consists of 32 bits. The upper 4 bits of the MSB side are reserved and all zeros. The next 12 bits are the Publisher ID. The lower 16 bits can be used arbitrarily by Publisher (who generates CD-ROM66).

This EEPROM 87 can be used as a bookmark function, for example, when a program is interrupted in the middle, the position is stored and resumed from the stored position when the program is resumed. Alternatively, the game score or password can be stored.

This service is attached to the following services.

Subservice 00h: Get Configuration Of Scratch Pad Memory

This subservice is a service for obtaining the state of the EEPROM 87. When this service is specified in registers AH and AL, the number of data blocks is output to register BX, and the size of the user data area is output to register CX.

Subservice 02h: Write Data

This service is a service for writing data into the EEPROM 87. EEPROM (87) sets the service-specific value in registers AH and AL, sets the application ID in registers BX and CX, sets the address of the application name in registers DS and SI, and addresses the data buffer in ES and DI. The data of the specified data buffer is written to the predetermined block. When this writing is performed normally, 0 is output to register AX, 1 is output when the data area is insufficient, and 2 is output when IDs are the same and different names exist.

In addition, since the number of characters is not specifically specified in the application name, data up to zero is treated as a name.

Subservice 03h: Read Data

This subservice is a service for reading data from the EEPROM 87. The inputs and outputs for each register are the same as for data write in subservice 02h. However, this subservice outputs the data of the application ID designated as read to the designated data buffer.

Subservice 04h: Delete Data

This service is a service for erasing data written to the EEPROM 87. When a service is specified in registers AH and AL, an application ID is specified in registers BX and DX, and an application name address is specified in registers DS and SI, data of the specified application ID is erased. If this erasure is performed correctly, 0 is output to register AX and 2 is output if the same ID exists but different names exist, or 3 if no data exists.

As shown in FIG. 14, when erasing data divided into blocks, it is also possible to theoretically specify and erase only the ID. However, in doing so, the user must remember the ID for each application and the operability is deteriorated. Therefore, in the present embodiment, as described above, not only the application ID but also the application name is stored as the format of each block. Thus, the user can easily select data to be erased from the name (application name).

Next, the operation of the apparatuses P1 to P3 shown in FIG. 10 will be described with reference to the flowchart of FIG. 15.

First, operation processing at system startup will be described. If it is detected in step S1 that the power supply is turned on, the process proceeds to step S2 and the BIOS is activated. This is in the state which each mechanism part of each apparatus can control. Next, DOS is started up in step S3. DOS installs the device driver in the next step S4. That is, MS-DOS reads CONFIG.SYS. This CONFIG.SYS describes the CD-ROMXA and PIEX drivers CDROMXA.SYS and PIEX.SYS, and CDROMXA and PIEX can be started.

In the next step (S5), DOS executes AUTOEXEC.BAT. SHELL.COM is executed from AUTOEXEC.BAT.

SHELL.COM determines whether a CD is inserted in the device in step S6. That is, the actuator of the optical pickup 71 shown in FIG. 8 is driven to start the focus servo loop. When the CD is mounted on the device, the focus servo loop is locked. On the other hand, if the CD is not mounted, the focus servo is not locked. The CPU 84 determines whether or not the CD is loaded from this focus lock state.

If it is determined that the CD is not mounted, the process proceeds to step S10, where the CPU 84 causes the LCD 100 to display a display for requesting the insertion of the disc. At this time, for example, the message 'Please insert a disc and restart the player.' Is displayed. This display continues until it is determined in step S11 that 15 seconds have elapsed since the start of display. When 15 seconds have elapsed, the process advances to step S9, the power supply is turned off, and the process ends at step S17.

On the other hand, in the case where it is determined in step S6 that the CD is inserted, the flow advances to step S7 to determine whether the CD was a normal music CD (CD-DA). In the case of a CD-DA, audio data is recorded in the track 1. The CPU 84 reads this track 1, and if audio data is recorded therein, determines that it is a CD-DA, and proceeds to step S8 to execute a program for reproducing the CDPLAYER, that is, the CD-DA. . This makes it possible for the user to play the CD-DA by performing various operations. When the reproduction of the CD-DA is finished, the flow advances to step S9, the power supply is turned off, and the process ends in step S17.

On the other hand, if it is determined in step S7 that the loaded CD is not a CD-DA, the process proceeds to step S12, where the CD is used in the present system among MMCDs (ie, various CD-ROMs). It is determined whether or not the CD is possible. In the MMCD that can be used in this system, a Primary Volume Descriptor (PVD) is recorded at the 16th frame position of 0 minutes 2 seconds. The following data is recorded in this PVD, for example.

As shown in Table 1, byte pointers (BPs) 1051 to 1053 of PVD describe 'PIX' as an identifying signature. The CPU 84 judges that this PIX can be read from the PVD as an MMCD, and as a CD-ROM which cannot be reproduced in this apparatus when it cannot read.

When it is determined in step S12 that the mounted one is not the MMCD, the flow advances to step S15 and an error display is performed. For example, a message of 'This disc is not playable on the Multimedia CD-ROM Player.' Is displayed on the LCD 100 at this time. This display continues until it is determined in step S16 that 15 seconds have elapsed. When 15 seconds have passed, the process proceeds to step S9, where the power supply is turned off, and the process ends in step S17.

On the other hand, when it is determined that the MMCD mounted at step S12 is MMCD, a display is requested to go to step S13 and to wait for a while. At this time, for example, 'Now Starting-up xxxxx. Please wait one moment. 'Is displayed on the LCD. In xxxxx, the disk names described in 1055 to 1086 BP of the PVD are displayed.

The process then advances to step S14, where a search for EXEME.EXE or EXEME.COM is performed and the processing is executed. After the process of step S14, it progresses to step S9, a power supply is turned off, and a process is complete | finished again in step S17.

Next, the processing of the subroutine in step S14 will be described in detail with reference to the flowchart of FIG. The process is started in step S20, and EXEEXE.EXE (or EXEME.COM) is searched for from the root directory on the CD-ROM 66 mounted in step S21. As shown in FIG. 13, EXEME.EXE or EXEME.COM is always recorded in the MMCD mounted on the devices P1 to P3. The CPU 84 stores this EXEME.EXE read from the CD-ROM 66 in the DRAM 91 at step S22. Next, the flow advances to step S23 to obtain an entry point of PIEX. By accessing this entry point, PIEX is configured to execute various service processes described above. The detailed processing of this entry point acquisition will be described later with reference to the flowchart of FIG.

When the entry point is acquired in step S23, the flow advances to step S24 to perform initialization processing of PIEX. This PIEX initialization process will also be described later with reference to the flowchart of FIG. 18.

In this manner, after the PIEX initialization process is completed, the flow advances to step S25 next, and then a process corresponding to the application program read out sequentially from the CD-ROM 66 is executed. Then, when the processing of the application is finished, the process proceeds to step S26 next, and after the PIEX end processing is performed, the process proceeds to step S27, where the process returns to step S14 of FIG. 15, and the process proceeds to step S9. Goes.

That is, in this embodiment, EXEME.EXE is necessarily read and the initialization process and the termination process described therein are executed. In addition, PIEX is read from time to time during application processing, and necessary processing is performed.

Next, with reference to the flowchart of FIG. 17, the process of acquiring the entry point in step S23 of FIG. 16 will be described in detail. First, the execution of the processing is started in step S30, and the device '$$ PIEX $$' is opened in step S31. PIEX has the device name '$$ PIEX $$' in any application. If the PIEX open processing is successful, the handle number is obtained. When it is determined in step S32 that this handle number is not obtained, that is, when the open processing of the device '$$ PIEX $$' does not end normally, the flow advances to step S36 and an error display is performed. That is, for example, a message of 'PIEX not found.' Is displayed on the LCD 100. The process then advances to step S37, where the power supply of the apparatus is turned off, and the processing ends.

If it is determined in step S32 that the handling number has been obtained (open processing of device '$$ PIEX $$' is completed normally), the process proceeds from step S32 to step S33, Get an entry point with the IOCTL service. In order to execute the above PIEX service, it is necessary to issue a CALL FAR between entry points managed by this MS-DOS. Therefore, this entry point must be acquired beforehand to execute various services of PIEX. In step S34, it is determined whether or not the process of acquiring this entry point has been normally performed. If the entry point has not been normally acquired, the process proceeds from step S34 to step S36 and displays an error, and then, at step S37, the device is turned off to terminate the processing.

If it is determined in step S34 that the entry point has been normally acquired, the process returns to step S23 of FIG. 16 from step S35.

In this manner, after entry points necessary for executing various services of PIEX are acquired, the PIEX initialization process shown in FIG. 18 is executed in step S24 of FIG.

The initialization process of PIEX is started from step S40, as shown in FIG. 18, and service number 00h and subservice number 04h for executing the initialization service of PIEX described above in step S41 are set in registers AH and AL, respectively. do. Next, in step S42, 'FAR CALL' to the entry point of PIEX is performed. Then, the process returns to step S24 of FIG. 16 from step S43.

When PIEX1 of the apparatus PI shown in FIG. 10 receives an inter-segment call for initialization processing, as shown in FIG. 20A, a return process is immediately performed in step S61. That is, in this case, the initialization processing is immediately terminated without performing special processing.

On the other hand, in the apparatus P2 of FIG. 10, as shown in FIG. 20B, the CLUT (Color Look Up Table) stored in the RAM 102 is set in the same way as the apparatus P1 in step S71. Processing is performed. After that, the process returns to the original process from step S72.

The device P1 can display 256 kinds of colors (fixed colors), while the device P2 displays 256 kinds of colors arbitrarily selected from about 128 million kinds of colors (fixed colors) by the CLUT. It is a structure that can be done. For this reason, the device P2 has a CLUT in the RAM 102 and is configured to display 256 kinds of colors set therein.

In this case, since the application program of the device P1 does not take into account the process of specifying 256 kinds of colors in the CLUT, when this application program is executed on the device P2, the color can be displayed when PIEX2 does not exist. There will be no. However, in the present embodiment, as shown in Fig. 20B, predetermined 256 kinds of colors, such as the apparatus P1, are initially set in the CLUT in step S71 of PIEX2. This makes it possible to write the application program developed for the device P1 to the device P2, and the same processing is reproduced.

If the processing is terminated with the 256 types of colors of CLUT set for the currently loaded CD-ROM 66, correct color display is performed when a different CD-ROM 66 is mounted for this device P2. There is a possibility that it will not be. Thus, the process of ending PIEX shown in step S26 of FIG. 16 is performed as shown in FIG.

That is, the service number 00h and the subservice number 05h, which start the processing from step S50 and start the termination service described above in step S51, are set in the registers AH and AL, respectively. In step S52, a FAR CALL for an entry point of PIEX corresponding to this set value is issued. After that, the process returns to the original process from step S53.

PIEX1 of the apparatus P1 is subjected to the return process immediately at step S81 as shown in Fig. 21A. That is, in this case, substantially no special processing is performed. On the other hand, in the apparatus P2, as shown in FIG. 21 (B), a process of returning the CLUT to a state before PIEX initialization is executed in step S91, and then the process returns to the original process from step S92. In this way, the CLUT is returned to the state before initialization (the default state) performed for the application program of the apparatus P1, so that correct color display is possible even when a CD-ROM is mounted thereafter.

On the other hand, when data is recorded as the processing of EXEME.EXE in the application processing of step S25 in FIG. 16, the processing shown in the flowchart of FIG. 22 is executed, for example. In step S101, service number 04h and subservice number 02h for writing data to EEPROM 87 are set in registers AH and AL. The address in which the application ID is stored in the registers BX and CX, the application name is stored in the registers DS and SI, and the address of the buffer in which the data written in the registers ES and DI are stored are set. When such a set is made, an inter-segment call to the entry point of PIEX corresponding to such input data is issued in step S102. After that, the process returns to the original process from step S103.

In the PIEX1 of the device P1, when an intersegment call to the entry point for writing to this EEPROM 87 is received, as shown in Fig. 23A, the application ID, Fill in the data with the application name. Then, the process returns to the original process from step S112.

On the other hand, in PIEX2 of the apparatus P2, when receiving a call to this entry point as shown in Fig. 23B, a process of writing data via the DOS to the HDD 111 is performed in step S121. After that, the process returns to the original process from step S122.

In this way, when the EEPROM 87 is installed in the device P1 and the EEPROM 87 is not installed in the device P2, but the HDD 111 is installed instead, the application program prepared for the device P1 is used in the device P2. The data can be written correctly even if the EEPROM 87 is not provided. This prevents the application program from being applied.

Again, the following is also considered. That is, as shown in FIG. 24, for example, in the apparatus P1, (F1) to (F5) are prepared as the function keys 22, and the SP key 28 is provided. In contrast, in the apparatus P2, (F1) to (F10) are provided as the function keys 22, and the SP key 28 is not provided. In such a case, when the application program developed for the device P1 is used in the device P2, the process corresponding to the SP key 28 in the application program cannot be executed in the device P2. If the function keys F6 to F10 are operated without being installed in the device P1, there is a possibility that an application program developed for the device P1 may malfunction.

In this case, therefore, the return processing is immediately performed in step S131 when the initialization processing is called to PIEX1 of the apparatus P1 as shown in Fig. 25A. That is, in this case, substantially no special processing is performed. On the other hand, in PIEX2 of the apparatus P2, as shown in FIG. 25B, the code of the function keys F6 to F9 is set not to be delivered to the application program at step S132, and the code of the function key F10 is set. Is replaced by the SP key 28 code of the device P1, and the BIOS is replaced, and then the process returns to the original processing from step S133.

In this way, the function key F10 of the device P2 can be used in place of the SP key 28 of the device P1, and even if the function keys F6 to F9 are operated, the application program developed for the device P1 malfunctions in the device P2. Is prevented.

26 schematically shows the above processing. That is, when the key matrix 81 outputs a signal corresponding to the operated key to the keyboard controller 82, the keyboard controller 82 supplies data corresponding to this input to the DRAM 91 and stores it once. In this DRAM 91, a command to execute the key processing of the BIOS is usually described in the area 91A. Thus, the key processing of the BIOS is usually executed and the normal processing in the apparatus P2 is executed.

On the other hand, when the application program developed for the device P1 is written in the device P2, the description in the area 91A of the DRAM 91 is replaced with the description for executing the key processing of the PIEX2. For this reason, when the application program for the device P1 is executed, the key processing of PIEX2 is executed corresponding to the input from the key matrix 81. As a result, the application program developed for the device P1 can be used correctly in the device P2.
