Description

User Management and User Rating Management of DVDP

The present invention relates to a user management and user rating management method of a DVDP to define user information for implementing parental management in a DVDP (Digital Video Disc Plater).

In general, DVD is a large media that can store several GB of data including moving images on a 12cm optical disc such as a current CD using MPEG2 moving picture compression technology.

DVDP is a player that can play these DVDs, and can play high-quality, high-quality digital video for about two hours or longer.

In addition, the DVD can be interactive according to the specification, and the required moving picture can be automatically selected and played according to the rank.

Fig. 1 shows a block diagram of a general DVDP, in which the CPU 1 controls the front end 2 to obtain a stream from the disc, so that the system decoder 3a of the back end 3 receives the stream. To be entered.

The stream inputted to the system decoder 3a is demultiplexed and input to the MPEG2 video decoder 3b, the subpicture decoder 3c, and the audio decoder 3d to reproduce video and audio.

The EEPROM 4 or RAM (or flash memory) 5 can be used to provide data that the player needs to keep permanently, and these data can be modifiable data.

In this DVDP, the specification of the parental management is defined, but user information is required to fully implement it, but it is not defined yet.

The present invention has been made in view of the above, and the user management and user grade management of the DVDP for registering the user, setting the parental level and managing the user so that the DVDP can be managed according to the user management and the parental level (user grade) The purpose is to provide a method.

In order to achieve the above object, the present invention provides a player menu display and setting when the system is used for the first time, a first step of displaying a player menu, and checks whether an administrator code is registered when selecting a user registration menu from the player menu. A second step proceeding to the first step if the manager code is not matched and a third step of displaying a user registration menu if the manager code is not registered or the manager code is matched in the second step, and the user registration menu Depending on the display, the country code setting menu, administrator code registration menu, user registration and deletion menu are selected, and the country code, administrator code, user registration element ID, password, and parental level are stored in the corresponding fields. When deleting, do it in the user list Perform the fourth step of removing the user, enter the user ID or Enter key if not using the system for the first time, define country code and default user setting as default value when entering the enter key, and then set the value set as the default value. It is assigned to actual system parameter values such as country code and parental level.When a user ID is entered, it compares the registered ID with the entered ID and enters a password if it is matched. The level is read and given as the system parameter value so that the DVDP is automatically played according to the country code and the user's parental level.

2 (a), (b) and 3 (a), (b) shows a flowchart for performing a user management and user rating management method of the DVDP according to the present invention, which is a DVDP as shown in FIG. Is performed in the system.

First, the present invention initializes the CPU and the built-in device when it is powered on (S1), and then determines whether it is the first use (S2). Here, the first use is determined as the value of the first access field, and the minimum access field is set to a non-zero value at the time of product shipment.

If it is determined to be the first use, a subroutine for displaying the player menu and setting the menu is performed (S3). If it is not the first use, a screen for inputting a user is displayed (S4). If such a screen is displayed, a user ID is input. Or just press enter (S5).

If it is determined in step S5 that the enter key has been input, and it is determined that the enter is input, a country code and a basic user are set (S7).

In step S7, the lowest grade is applied during playback without a user ID, and a default value is set when the country code is zero.

In addition, the system parameter of the DVDP is set (S8), and the system parameter reads from the memory the value set as the default value in step S7 and assigns it to the actual system parameter value. (System Parameter) 13 = Assigned to the parental level.

On the other hand, if it is determined in step S6 that the input key is not entered, the user ID is input, and thus the registered ID is compared with the input ID, which is performed by the number of registered IDs (S9).

If the registered ID and the input ID do not match, it indicates that the user is not registered on the screen and returns to step S4 (S10).

If the registered ID matches the input ID, the screen is displayed to input a password (S11). If the password screen is displayed, the password is input and then the enter key is input (S12).

In operation S13, the system parameter is set using the control code and the parental level of the user if the match is matched with the user password (S13).

If the user password and the input password does not match, the password is input again, and if the password is not matched up to a predetermined number of times (for example, 3 times), the process returns to the step S7 (S15).

After the step S8 is performed, the selected control code and the parental level are automatically played (S16). When the player menu is called by the user in the stop state, the process returns to the step S3.

In addition, after performing the step S3, it is determined whether the user registration has been updated, and when it is determined that the user has been regenerated, the process proceeds to the step S4.

In addition, the said subroutine is demonstrated with FIG. 3 (a) and (b).

First, a player menu as shown in FIG. 4 is displayed (S101).

If it is selected in the player menu, it is terminated. Otherwise, it is determined whether user registration is selected (S102, S103).

If it is determined that the user registration is not selected, another menu is processed and the process returns to step S101 (S104). If it is determined that the user registration is selected, it is checked whether the administrator code is registered (S105).

If it is determined in step S105 that the manager code is not registered, the user registration menu as shown in FIG. 5 is displayed (S106). If it is determined that the manager code is registered, the manager code is checked and matched to step S106. Return to step S101 (S107).

If it is determined that the country code setting menu is selected in the user registration menu (S108), and if it is determined that the country code setting menu is selected, the country code is selected and stored in the country code list (S109), and the country code is stored in the flash memory or the EEPROM. Stored in the country code field.

If it is determined in step S108 that the country code setting menu is not selected, it is determined whether the manager code registration menu is selected (S110). If it is determined that the manager code registration menu is selected, the manager code is received and stored (S111). The code is stored in flash memory or in the manager field of the EEPROM.

In addition, if it is determined in step S110 that the administrator code registration menu is not selected, it is determined whether the user registration / delete menu is selected (S112). If it is determined that the selection is selected, the user registration such as a new ID, password, and parental level is registered in the user list. The element is received and stored, and the user ID, password, and parental level are sequentially input and stored in the user ID, password, and parental level fields.

When deleting a user, the user selects and deletes the cursor from the user list, and when registering and deleting, the user information list is updated (S113).

If it is determined in step S112 that the user registration / deletion menu is not selected, it is determined whether to select the end menu, and if it is finished, the process returns to the step S101, otherwise the process returns to the step S106 (S114).

The method of receiving a user input or displaying the screen may be different for each player, and the menu selection process may be different. The screen display may be performed as shown in FIGS. 4 and 5, or may be a pull-down menu.

6 illustrates various data formats stored in an EEPROM or a flash memory.

As described above, the present invention enables a small effective parental management in DVDP, thereby providing a lock function for various users.
