This multi-player software 122d corresponds to game software and music software. The ROM 220 mounted on the board 200 has an ID 220 for CD confirmation.
a, check routine and program loader 220b,
Software such as a compressed VCD (video CD) player 220c and a compressed PCD (photo CD) player 220d is stored.

FIG. 5 is a flow chart of a process for the system to identify the CD 70 newly mounted on the multimedia player. CD of unknown type in step S10
When is mounted, it is checked in step S11 whether the CD is a digital audio music CD (CD-DA). C
If D is CD-DA, the process proceeds to step S12, it is confirmed that the CD is CD-DA, and C is determined in step S20.
Load the D-DA player software. This CD-D
The player software for playing the music of A is the boot R of the main unit.
It is included in the multi-player software 122d of the OM 122.

If the CD is not CD-DA, step S
Check if it is a game CD at 13. If it is a game CD, it is confirmed in step S14 that the CD is a game CD, and the player software of the game CD is loaded in step S20. When the CD is not the game CD, the process proceeds to step S15. In step S15, it is checked that the board 200 is attached to the system main body 100. When the board 200 is mounted, the VCD and ICD player software stored in the ROM 220 of the cartridge board is expanded to the RAM 11 of the main body.
6 is transferred. If it is confirmed that the cartridge board 200 is mounted, the process proceeds to step S16. In this step S16, the CD loaded in the CD player
Check if is PCD (Photo CD).

If PCD, in step S17 PC
It is confirmed to be D, and the PCD player software is read from the RAM 116 and loaded in step S20. If it is not PCD, VCD is determined in step S18.
Check if it is (video CD). When VCD,
In step S19, it is confirmed that the VCD is a VCD, and in step S20, the VCD player software is read from the RAM 116 and loaded.

When it is confirmed in step S15 that the cartridge board 200 is not mounted on the main body 100, the process proceeds to step S30, and the CD on the CD player is read.
Check if it's a CD. If it is PCD, the process proceeds to step S35, and a message "Please insert the board" is displayed on the display. The user inserts the board 200 into the main body according to this instruction and re-executes the above-described processing.

In step S32, it is checked whether the CD is a VCD. If the CD is a VCD, the process proceeds to step S35.
The message "Please insert the board" is displayed. The user inserts the board 200 into the main body according to this instruction and re-executes the above processing. The CD mounted on the CD player of the main body is a CD-DA, a game CD, a PCD,
If the CD does not correspond to any of the VCDs, "This C
The message "D cannot be played back" is displayed, and the process ends.

FIG. 6 is a flow chart of a process for loading player software corresponding to each CD. In step S50, the CD-DA mounted on the CD player
If it is a CD-DA, it is checked in step S60.
To display the operation screen for CD-DA on the display,
Play music according to the operation instructions. If the CD is not a CD-DA, it is checked in step S51 if it is a game CD. If it is a game CD, the game software is loaded and the game is executed in step S52.

If it is not a game CD, the process proceeds to step S53, and the cartridge board R inserted in the main body is read.
Check the OM ID and make sure the proper cartridge board is installed. When the proper cartridge board 200 is mounted, step S54
Go to and check if the CD is a PCD. If it is a PCD, it is compressed and stored in the board ROM. PC
The D player software is expanded, loaded via the RAM of the main unit, and executed. At this time, the multimedia player functions as a PCD player.

If it is determined in step S56 that the VCD is a VCD, the VCD player software compressed and stored in the board ROM is expanded and loaded and executed in step S57. At this time, the multimedia player functions as a VCD player. If the genuine cartridge board is not inserted or the CD is PCD, V
If the medium is other than the CD, a message to that effect is displayed on the operation screen in step S60, and the process ends.

[0018]

As described above, according to the present invention, the ROM of the cartridge board mounted in the player body is provided in the player capable of supporting various kinds of CD media.
It stores player software for video CDs and photo CDs. When a music CD or game CD is loaded in the CD player, these media are played back by the player software stored in the ROM of the player body.
In the case of a video CD or a photo CD, the brake software is supplied from the ROM of the cartridge board and the reproduction is executed.

When the user mounts various CDs on the CD player, the player body discriminates the type of the CD, selects and loads the player software of the CD, and executes the reproduction. You can enjoy various media without needing. Further, since the player software for the video CD and the photo CD stored in the ROM of the cartridge board is stored as compressed data,
The effective use of the memory can be achieved, and a small capacity memory can be used. The ROM of this cartridge board stores player software corresponding to media other than the above-mentioned two types of CD player software, and constitutes a multimedia player for playing multimedia for playing more media. You can
