S 1 1), the control unit 5 transmits the input user ID or The user ID and password and the data (for example, co-data) recorded on the recording medium A are read, and the read user ID or the user ID and the password are read from the PLAYMENU folder A5 of the recording medium A. It is determined whether or not it is recorded in the XML user device setting information file A52 (or the binary user device setting information file A533) (step S12).

The execution order of steps S10 and S11 is not limited to the above. That is, step S11 and step S10 may be performed in this order.

In step S12, the entered user ID or user ID and password are recorded in the XML user device setting information file A52 (or the binary user device setting information file A53). If there is (Step S12; Yes), the control unit 5 performs a reproduction process based on the user device settings recorded in the XML user device setting information file A52 (Step S13). .

In step S12, the entered user ID or user ID and password are not recorded in the XML user device setting information file A52 (or the binary user device setting information file A53). In this case (step S12; No), the control unit 5 performs a reproduction process based on the device settings stored in the memory 6 by default (step S14).

Note that the control unit 5 may execute the process of step S24 in the flowchart of FIG. 8 instead of the process of step S14.

Here, each processing of steps S20 to S23 in the flowchart of FIG. 8 is the same as each processing of steps S10 to S13 in the flowchart of FIG. 7, and for simplification, step S20 The description of S23 will be omitted, and only step S24 will be described. In other words, if the user identification information entered in step S2◦ is not recorded in the XML user device setting information file A52 (or the binary user device setting information file A53) ( Step S22; No), the control unit 5 displays on the display 10 that the content data of the recording medium A set in the step S21 cannot be reproduced (step S24).

As described above, the playback device 100 according to the first embodiment has an XML user device setting information file A 52 shared by a plurality of registered users and recorded for each registered user. When content data is played back from recording medium A, the user ID or user ID and password entered by the user who wants to play back the content data are recorded on recording medium A (that is, the XML user device setting information file). A5 2 or binary user device setting information file A53) Determines whether or not the force is recorded in the file, and if it is recorded, the registered user's XML user device setting information file A52 The reproduction process is performed based on the user device settings recorded in.

Therefore, different user device settings cannot be set for each category of user and content data, or even if the playback device 100 is available but such user device settings are not made at present, By playing back the recording medium A on which the XML user device setting information file A 52 in which the user device settings are recorded is stored, the user does not need to change the settings as necessary each time the playback is performed. Playback can be performed based on the user device settings desired by the user.

That is, content data can be reproduced based on user device settings that differ for each user.

The description in the first embodiment shows an example of the reproducing apparatus and the reproducing program according to the present invention, and the present invention is not limited to these.

Of the components of the playback device 100a shown in FIG. 9, the same components as those of the playback device 100 shown in FIG. 2 are denoted by the same reference numerals for simplification. Are omitted, and only the memory 6a and the reading unit 12 will be described in detail.

The memory 6a stores a reproduction program for performing the reproduction processing shown in the flowchart of FIG. The control unit 5 executes the reproduction program stored in the memory 6a to perform a reproduction process.

The reading unit 12 reads the user identification information from the authentication recording medium C mounted via the authentication recording medium 揷 entrance 31 provided on the operation surface shown in FIG. It transmits to the control unit 5 via 9. In this case, the input controller 9 converts the user identification information input from the reading unit 12 into data that can be read by the control unit 5. Here, on the authentication recording medium C, for example, an authentication key indicated by reference numeral B5 in FIG. 5 is recorded. This authentication key is preferably different from the registered user ID and password in terms of security. For 21, insert recording medium A. This is a recording medium insertion port for the user.

The authentication recording medium C is a writable and readable magnetic card, a memory card, a USB memory, or the like on which an authentication key is recorded.

Next, the operation of the playback device 100a will be described with reference to FIG. FIG. 11 is a flowchart illustrating a reproduction process by the reproduction device 100a.

First, the user ID or the user ID and the password are input via the input unit 7 or the remote control receiving unit 8 (step S30), and the authentication recording medium C is set in the reading unit 12 (step S31). Further, when the recording medium A is set in the reading unit 1 (step S32), the control unit 5 stores the input user ID or the user ID and the password and the recording medium C for authentication. The recorded authentication key and the data (content data, etc.) recorded on the recording medium A are read, and the read authentication key, user ID or user ID and password are stored in the PLAYMENU folder A of the recording medium A. It is determined whether the force is recorded in the XML user device setting information file A52 (or the binary user device setting information file A53) in step 5 (step S33).

The execution order of steps S30 to S32 is not limited to the above. For example, the order may be step S31, step S32, and step S30, or the order may be step S32, step S30, and step S31.

In step S33, the user ID or the user ID and the password input in step S30 and the authentication medium read out from the authentication recording medium C set in the reading unit 12 in step S31. When the authentication key is recorded in the XML user device setting information file A52 (or the binary user device setting information file A53) in the PLA YME NU folder A5 of the recording medium A (step S33; Y es), the control unit 5 performs a reproduction process based on the user device settings recorded in the XML user device setting information file A 52 (step S34).

In step S33, the user ID or user ID and password entered in step S30 and the authentication recording medium C set in the reading unit 12 in step S31 are read out. If the authentication key and the authentication key are not recorded in the XML user device setting information file A52 (or the binary user device setting information file A53) in the PLAYMEN U folder A5 of the recording medium A (step S33; No), the control unit 5 performs the reproduction process based on the device settings stored in advance in the memory 6a by default instead of the XML user device setting information file A52 (step S35).

Note that the control unit 5 may execute the process of step S45 shown in the flowchart of FIG. 12 instead of the process of step S35.

Here, each processing of steps S40 to S44 in the flowchart of FIG. 12 is the same as each processing of steps S30 to S34 in the flowchart of FIG. Description of S40 to S44 will be omitted, and only step S45 will be described.

That is, the user ID or the user ID and the password input in the step S40, the authentication key read from the authentication recording medium C set in the reading unit 12 in the step S41, and Is not recorded in the XML user device setting information file A52 (or the binary user device setting information file A53) in the PLAYMENU folder A5 of the recording medium A (step S43; No), the control unit 5 Then, the fact that the content data of the recording medium A set in the step S42 cannot be reproduced is displayed on the display 10 (step S45). In the second embodiment, steps S40 and S41 are both executed. However, the present invention is not limited to this, and only step S41 is executed without executing step S40. You may do it. In this case, instead of performing the authentication using the user ID or the user ID and the passcode, the user can be authenticated only with the authentication key obtained from the authentication recording medium C alone. The input of the user ID or the user ID and the password via the receiving unit 8 can be omitted.

As described above, the playback device 100a according to the second embodiment includes an XML user device setting information file A52 shared by a plurality of registered users and registered for each registered user. When reproducing content data from the recorded recording medium A, is the authentication key, user ID or user ID and password of the user who intends to reproduce the content data recorded on the recording medium A? It is determined whether or not it is recorded. If it is recorded, the reproduction process is performed based on the user device settings recorded in the XML user device setting information file A52 of the registered user. The user ID or the user ID and the password are input via the input unit 7 or the remote control receiving unit 8, and the authentication key is read from the authentication recording medium C via the reading unit 12.

Therefore, the user is authenticated based on the authentication key, user ID or user ID and password input via the input unit 7 or the remote control receiving unit 8, so that more reliable authentication can be performed. Security is improved. Also, since only the authentication key read from the authentication recording medium C via the reading unit 12 is used to authenticate the user, the user ID or the user ID is input to the input unit 7 and the remote control. This is convenient because it is not necessary to enter a password each time.

Note that the description in the second embodiment shows an example of the reproducing apparatus according to the present invention, and the present invention is not limited to this. Playback device 10 in the present embodiment The detailed configuration and detailed operation of 0a can be appropriately changed without departing from the spirit of the present invention.

For example, the playback device 100a may be included in an AV device such as a DVD player, or may be included in a personal computer.

As described above, in the first and second embodiments, the device settings related to the playback process in the playback devices 100 and 100a are recorded in the user device setting information. However, the present invention is not limited to this. Device settings for controlling various operations of the raw devices 100 and 100a (for example, a display format on the display 10) may be recorded.

Various data may be encoded and recorded on the recording medium A. In such a case, the reading unit 1 waits for input of information (decoding program) for decrypting the data, and encrypts various data from the recording medium A based on the input decoding program. Release and read the data. Industrial applicability
