BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an area management method in the recording medium reproducing apparatus of the present invention will be described based on specific embodiments.
[0022]
(Embodiment 1)
2 and 3 show a recording medium reproducing apparatus according to the present invention.
FIG. 2 shows a recording medium reproducing apparatus having a function of managing a reproducible area (Embodiment 1). Reference numeral 210 denotes an optical disc reproducing unit for reproducing the set optical disc 230; 211, a local data setting unit for setting a local number unique to the device; 212, a local management discriminating unit; Code) and the device-specific region data output from the region data setting unit 211.
[0023]
Numeral 250 is a detachable area data holding means which is detachable from the optical disk reproducing section 210 via the area data acquiring means 220. When the area data acquiring means 220 is a flash memory card reader, a detachable area data holding means is provided. Reference numeral 250 denotes a flash memory card.
[0024]
Reference numeral 221 denotes a regional data acquiring unit of the regional data acquiring unit 220, which sets regional data read from the flash memory card 250 inserted into the flash memory card slot of the regional data acquiring unit 220 in the regional data setting unit 211.
[0025]
The area data setting unit 211 outputs a corresponding area number from “1” to “8” to the area management determination unit 212 according to the output of the area data acquisition unit 221.
The region management determining unit 212 compares the region management information of the optical disk 230 with the region data set in the region data setting unit 211, and outputs a reproduction signal from the optical disk 230 to the image display device 240 as a reproduction signal when they match. .
[0026]
With this configuration, the setting of the local data setting unit 211 of the optical disk reproducing unit 210 can be updated by inserting the flash memory card 250 in which appropriate local data has been written into the throttle of the local data obtaining unit 220, and Even when the installation location of the playback device is a high-frequency shielded space where GPS signals cannot be received, local data can be set in the optical disc playback unit 210.
[0027]
Therefore, even with the same optical disk reproducing apparatus, an optical disk having different regional management information can be reproduced by updating the setting of the regional data setting unit 211.
[0028]
Further, in addition to the regional data, information specific to each optical disk reproducing device is written in the flash memory card 250. For example, in the local data setting unit 211, the specific reproducing device information of the optical disk reproducing unit 210 and The update is permitted by checking the playback device information set in the flash memory card 250, and a flash memory card used in another optical disk playback device cannot be used.
[0029]
This can prevent the area data from being easily set by replacing a plurality of flash memory cards.
A specific rewriting method of the flash memory card 250 is performed by, for example, a rewriting device placed in a store, and the region data to be rewritten is always the region data of the place where the rewriting device is placed.
[0030]
When rewriting the area data setting unit 211, the flash memory card 250 in which the target area data is written is inserted into the throttle of the flash memory card reader 220. When the power of the optical disk reproducing unit 210 is turned on in this state, the flash memory card 250 receives power supply from the optical disk reproducing unit 210, and the optical disk reproducing unit 210 automatically obtains the regional data from the flash memory card and sends it to the optical disk reproducing device. Rewrite the set regional data. Once the regional data is set, it can be used even if the flash memory card is not inserted.
[0031]
The above-described updating of the regional data was automatically executed. However, as shown in FIG. 3, a series of operations for rewriting the regional data can be realized by a user interface such as an OSD (On Screen Display) for displaying a series of operations on the screen of the image display device 240. Thus, it is possible to more clearly recognize that the regional data has been rewritten.
[0032]
Specifically, in step 301, an initial setting menu screen is displayed on the screen of the image display device 240. Here, when the fourth "change of regional data" is selected by using a selection button of the remote control slave unit attached to the optical disk reproducing unit, in step 302, the work of updating the regional data is displayed on the screen of the image display device 240. An instruction screen is displayed. When the flash memory card 250 in which the target area data is written is inserted into the slot of the flash memory card reader 220 according to the contents of the work instruction screen, the screen switches to step 303 or step 304.
[0033]
Step 303 is a case where the flash memory card 250 received immediately after step 302 satisfies the regulation, and the message “Regional data is being read” is displayed on the image display device 240 until rewriting of the regional data setting unit 211 is completed. When the rewriting is completed, the completion of the update is displayed in step 305.
[0034]
Step 304 is a case where the flash memory card 250 received immediately after step 302 does not satisfy the rules. “This card cannot be used” is displayed on the screen of the image display device 240 for a specified time, and the process returns to step 302. Then, the user is prompted to insert the flash memory card 250 satisfying the rules.

In), a voltage conversion unit 550 is prepared for each combination of the commercial power supply voltage and the area code, and in each voltage conversion unit 550, not only a voltage-voltage conversion function suitable for the area of use but also a corresponding area code is set. ing.
[0042]
In this case, when the optical disk reproducing unit 210 is connected to the commercial power supply 560 via the voltage conversion unit 550 suitable for the use area, the area data set in the voltage conversion unit 550 is set in the area data setting unit 211. .
[0043]
With this configuration, when the voltage conversion unit 550 to which the area data is added in advance is connected, the area management information can be automatically updated according to the change of the power supply. The region management information is compared with the region-specific region code set in the region data setting unit 211 of the optical disk reproducing unit 210, and when they match, a reproduction signal from the optical disk is reproduced by the image display device 240.
[0044]
In this case, similarly to the case of the first embodiment, information unique to each optical disk reproducing unit is written in the voltage conversion unit 550 in addition to the local data, and the local data setting unit 211 writes the information to the optical disk reproducing unit. The reproduction apparatus information set in the voltage conversion unit 550 is compared with the reproduction apparatus information unique to the apparatus 210 to allow the update, and the voltage conversion unit 550 used in another optical disk reproduction apparatus is configured. , The setting of the local data in the local data setting unit 211 of the optical disk reproducing unit 210 cannot be executed.
[0045]
(Embodiment 4)
FIG. 6 shows a recording medium reproducing apparatus according to (Embodiment 4), which differs from the configuration of FIG. 2 in that the input voltage level of the connected commercial power supply is compared with the voltage level of each country, and specifically the region of use, specifically, The point is that a power supply determining means 600 for determining the country of use is provided.
[0046]

The area data is set in the area data setting unit 211 by the removable area data holding means 250 to which the area data has been added in advance. Further, the country code in use is determined from the commercial power supply voltage input to the power supply determination means 600, and the area management determination unit 212 determines the country code in use determined by the power supply determination means 600 and the local data setting. It is determined whether the area data is the same as the area data of the section 211, and if they are the same, the area management information of the optical disk 230 is compared with the area-specific region code set in the area data setting section 211 of the optical disk playback section 210, and a match is obtained. Then, the reproduction signal from the optical disk 230 is reproduced by the image display device 240.
[0047]
Thus, by providing the power supply determining means 600 for comparing the input voltage level of the commercial power supply with the voltage level of each country, the commercial power supply voltage level is compared with the voltage level of each country, and the area of the removable area data holding means 250 is compared. You can judge whether the data is correct and prevent malicious modification.
[0048]
Note that the combination of the power supply determining unit 600 and the area management determining unit 212 can be similarly implemented in the second embodiment and the third embodiment.
(Embodiment 5)
FIG. 7 shows a recording medium reproducing apparatus according to (Embodiment 5), which differs from the configuration of FIG. 2 in that a network data position determining means 700 is provided instead of the local data acquiring means 220 and the removable local data holding means 250. It is characterized by having.

[0050]
The operation of the optical disk reproducing apparatus thus configured will be described below.
First, the network data position determining means 700 connects to the server 730 via the Internet 701. Since the server 730 is provided for each region and cannot be connected from other regions, the network data position determining means 700 automatically searches for a connectable server, receives the regional data from the server 730 after finding the connectable server, and automatically receives the server. Next, the regional data is set in the regional data setting unit 211.
[0051]
The region management discriminating unit 212 collates the region management information of the optical disk 230 with the region data (region-specific region code) set in the region data setting unit 211 of the optical disk reproducing unit 210. The reproduction signal is reproduced by the image display device 240.
[0052]
As described above, the provision of the network data position determining means 700 in place of the removable area data holding means 250 eliminates the need for a human setting in the optical disc reproducing apparatus, and can automatically update the regional management information. .
