The present invention relates to a digital TV, and more particularly, to a digital TV and a method for receiving a program for each user for limiting broadcasting for each user.

In general, the expected number of channels of digital television is tens of times that of current analog television, and each channel is allocated to provide over-the-air broadcasting, cable broadcasting, and digital broadcasting. .

In addition, the digital broadcast provides corresponding EPG (Electonic Program Guide) information when the broadcast signal is transmitted, and the EPG information includes broadcast information and broadcast grade of each channel.

The user sets the channel preferred by the user with reference to the EPG information for the tens to hundreds of channels of the digital TV so that the user can switch only the set channel when the channel of the digital TV is switched.

In addition, by classifying the channels that the user can view according to the user's age or the broadcasting grade of each channel, the broadcasting channel is limited to not be displayed if the grade is not viewable by setting the broadcasting restriction function for the corresponding channel.

The digital TV according to the related art described above has the following problems.

First, since the preference of each individual for each channel is different when several users set the preference channel, if the preference channel is set in the digital TV set, the channel that can be switched when switching the preference channel is the same as the preset preset for multiple users. The channel was limited to only.

Second, in consideration of the broadcast grade of each channel according to the user's age or broadcast content, there was an inconvenience in that the user should set a broadcast restriction function for each channel according to the user's age.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to set a personal preference channel for each user in setting a preference channel of the digital TV and its use. To provide a program receiving method for each user.

Another object of the present invention is to classify an allowable broadcast channel according to the age of each user or broadcast grade of a broadcast content, and to recognize each user using a TV and to automatically set a broadcast restriction function for a non-broadcast channel; It is to provide a program receiving method for each user.

Hereinafter, a digital TV and a program reception method for each user according to the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a digital TV according to the present invention. Referring to this, the digital TV according to the present invention will be described in detail as follows.

As shown, the digital TV according to the present invention is a digital TV, a key input unit 100 for inputting an ID / password and setting information of a user (including an administrator), program information received from the outside, and the key input unit. First and second memory units 110 and 120 for storing ID / password and setting information of each user input through 100, and the program information may be re-received at predetermined intervals. And a controller 140 for classifying / retrieving a broadcast signal that can be received according to program information stored in the second memory units 110 and 120 and outputting a control signal to limit the display of the broadcast signal. A second tuner 130 for re-receiving the program information at predetermined intervals according to a control signal and a broadcast signal received from the outside according to a control signal of the controller 140. It is configured to include a display unit 180 for displaying.

The broadcast signal is received through the first tuner 150 and the decoder 160 for decoding the broadcast signal received through the first tuner 150 and an image for processing the decoded signal to be displayed. It is configured to further include a processing unit 170.

In addition, the controller 140 allows the program information to be re-received through the second tuner 130 at predetermined time intervals so that the programs are stored in the first and second memory units 110 and 120. Update the information automatically.

In the present invention, the user using the TV includes an administrator and a non-administrator user. Here, the TV is set with an administrator having at least one ID and password managing the TV set. In addition, a user-specific viewing mode is set such that a plurality of users (including administrators) using the TV can use the TV for each user with each personal information (ID / password) and setting information. The TV is controlled and used according to each user's personal information and setting information.

In this case, the personal information is an ID and password directly set by the administrator and non-administrator users, and the setting information is the permission level of each user input by the administrator managing the TV set and personal broadcasting information directly set by each user other than the administrator. to be.

Here, the personal broadcast information may be a preference channel, a broadcast time reservation, etc., which the user prefers, and the allowance level is set by the administrator according to each user's personal age and broadcast content.

When using the TV set for the user-specific viewing mode, if each user inputs his or her personal information (ID / password) through a key input unit 130 such as a remote controller or a key panel, the control unit 140 controls the input personal information. The setting information and the program information may be read from the second memory unit 120 and transmitted to the first memory unit 110.

In addition, the controller 140 requests the broadcasting station through the second tuner 130 to receive the program information again so that the program information read from the second memory unit 120 can be received again.

The program information stored in the second memory unit 120 is updated when the program information is changed by comparing the re-received program information with previously stored program information read from the second memory unit 120.

In this case, the program information is information such as broadcast time, broadcast content or broadcast grade of each channel of the broadcast signal.

Meanwhile, at the same time as the program information is re-received, the first tuner 150 continuously receives a broadcast signal corresponding to a channel selected by an administrator or a user or a channel most recently watched when the TV is powered on. ) And outputs the decoded broadcast signal to the display unit 180 through the image processor 170 according to program information stored in the second memory unit 120 and corresponding setting information of an administrator or a user.

In displaying the broadcast signal received through the first tuner 150, the control unit 140 determines the setting information corresponding to the ID input by the user and receives the broadcast received through the first tuner 150. If the signal is a broadcast signal of the user's tolerance level set by the administrator is displayed.

On the other hand, if the broadcast signal is not a broadcast signal of a tolerance level, the controller 140 automatically sets a broadcast restriction function on the broadcast signal so that it is not displayed or not searched when the channel is automatically scanned.

On the other hand, if the TV does not have a user-specific viewing mode is set as shown in the conventional TV power on (On) of the broadcast signal selected by the user or the most recently watched broadcast signal to the first tuner 150 To tune and display.

Figure 2 is a flow chart showing a user-specific program receiving method of the digital TV according to the present invention, with reference to this will be described in detail the user-specific program receiving method of the digital TV according to the present invention configured as described above.

As shown in the drawing, personal information and broadcast setting information of a user (a manager and a non-administrator) are set together with the power of the digital TV (S100 to S110).

At this time, the recently watched broadcast signal is tuned and received through the first tuner 150 with the TV turned on.

In operation S120, the TV determines whether a user-specific viewing mode is set.

As a result of the determination (S120), if the user-specific viewing mode is not set, the broadcast signal received through the first tuner 150 is displayed (S130).

On the other hand, if the determination result (S120), the user-specific viewing mode is set, an input screen for inputting personal information, that is, ID and password is displayed (S140).

Subsequently, an ID and a password are input to the input screen (S150), and it is determined whether the input password matches a preset password corresponding to the ID (S160).

As a result of the determination (S160), if the passwords match, previously stored setting information and program information corresponding to personal information of the ID (administrator or non-administrator user) are read from the second memory unit 120 (S170).

Subsequently, by continuously receiving a broadcast signal corresponding to a recently viewed channel through the first tuner 150 and re-receiving the read program information (S180), the re-received program information and the read program information coincide with each other. It is determined whether (S190).

In this case, the program information is re-received repeatedly every predetermined time set in the controller 140.

If the re-received program information and the read program information do not match, the second memory unit 120 updates the pre-stored program information according to the re-received program information (S200).

On the other hand, if the re-received program information and the read program information is the same as the determination result (S190), the broadcast signal received through the first tuner 150 can be broadcasted according to the user's setting information corresponding to the ID. Grasp and classify whether having a grade (S210).

Subsequently, it is determined whether the broadcast grade of the broadcast signal received through the first tuner 150 is a broadcast-allowable grade (S220), and if the broadcast-cast signal is displayed (S230), the user corresponding to the ID is allowed. If the broadcast signal is not broadcast out of the grade, the parental control function (display lock) is automatically set to not be displayed (S240).

Here, the step of setting personal information and broadcast setting information of the user (administrator and non-administrator user) (S110) will be described in detail with reference to FIG. 3.

First, a predetermined key of a key input unit 100 such as a remote controller or a key panel is input or an OSD (On Screen Display) is executed to display the viewing mode menu screen for each user as shown in FIG. 4A (S300). In this case, the viewing mode for each user includes sub-menus of an administrator mode and a user (non-administrator user) mode.

In operation S310, it is determined whether an administrator mode is selected among the viewing mode menus for each user, and if the administrator mode is not selected, it is determined whether a user mode is selected (S320).

As a result of the determination (S320), if the user mode is selected, as shown in FIG. 4B, a submenu of the user mode such as user registration / change and user broadcast information setting is displayed.

If each user wants to set his or her ID and password, the user is registered as the user (non-administrator) by selecting 'user registration / change' and inputting the ID and password on the displayed input screen as shown in FIG. 4C (S330). In addition, the registered ID and password may be changed through the 'user registration / change' menu.

Then, when each user has a user ID and password set and registered as a user, personal broadcasting information such as a preferred channel is set (S340).

On the other hand, if the administrator mode is selected (S310), as shown in FIG. 4D, a submenu of the administrator mode such as administrator registration / change, user permission level setting, and viewing mode on / off for each user is displayed. .

If you want to set the administrator's ID and password to register the administrator by selecting the 'Register Administrator / Change' by entering the ID and password on the input screen displayed as shown in Figure 4e (S350). In addition, the registered ID and password may be changed through the 'administrator registration / change' menu.

At this time, if the administrator is registered through the 'administrator registration / change' menu during the initial setting of the TV, the administrator mode execution must log in through the administrator's ID and password.

If the administrator wants to set the permission level of the user, the user selects 'user permission level setting' and selects each user from the list as shown in FIG. 5A.

Subsequently, when the user who wants to set the permission level is selected by the administrator, an input screen for inputting the user's age and the permission level is displayed as shown in FIG. 5B.

The administrator inputs an allowance level according to the age and broadcast content of the administrator and the user on the input screen, sets the allowance level of each user, and sets the administrator's own personal broadcast information (S360).

In this case, the broadcast contents are classified into S (Sexual Situations), V (Violence), L (Coarse or Crude Indecent Language), D (Suggestive Dialogue), and FV (Fantasy Violence). Set allowance level in consideration of consideration.

As such, the permission level setting according to the broadcast content may be set to 'broadcast not possible (On)' or 'broadcastable (Off)', and may be selectively set whether to allow broadcasting according to the broadcast content.

For example, the memory contents are allocated to the second memory unit 120 in order of S, V, L, D, and FV, and when the user's tolerance level is set to '00001' through the manager, FV is assigned. Broadcasting is allowed only for the contents, and the remaining S, V, L, and D contents can be set so that broadcasting is not allowed.

In addition, in the setting of 'non-broadcasting', broadcasting may be conditionally allowed depending on the degree of selectivity, violence, etc. of the broadcasting contents.

For example, if the degree of selectivity (S) of the broadcasting contents has a rating of 0, 3, 5, and 7, the administrator sets the grade of each broadcasting content for each user, that is, the administrator sets the broadcasting permission level of a specific user. If it is set to '3', broadcasts having a selectivity of '3' grades are allowed, and broadcasts of '5' or '7' grades are restricted so that broadcasts can be conditionally allowed.

That is, the administrator ID registration, the user permission level setting, and the administrator setting information setting are performed in the administrator mode, and the user ID registration, setting information setting of each user, etc. are performed in the user (non-administrator user) mode.

In addition, the viewing mode for each user may execute the manager mode and the user mode using an OSD (On Screen Display) or the manager mode and the user mode through a key input unit 100 such as a remote controller or a key panel.

Therefore, in watching TV, IDs are given to users (administrators and non-administrators) so that they can be watched individually according to each setting information, and the administrator of the TV set sets the allowable broadcasting allowance level of each user for each user. Broadcast programs can be automatically restricted.

The digital TV according to the present invention and the program receiving method for each user according to the present invention by giving the ID to each user by limiting the broadcast that each user wants to watch according to the broadcasting permission level of each user (ID) set from a specific administrator There is an effect that can improve the reliability of the use.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
