The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a satellite broadcast receiver suitable for applying a method for restricting viewing of a satellite broadcast receiver according to an exemplary embodiment of the present invention, and includes a key input unit 10, a tuner and a demodulator 20, and a microcomputer 30. , An MPEG decoder 40, a signal processing unit 50, a memory unit 60, and an OSD unit 70.

The key input unit 10 is composed of key metrics on a remote controller or its own panel to generate a corresponding key signal to the microcomputer 30 by a user's operation, and the microcomputer 20 is provided from the key input unit 10. Each control signal is generated to perform a corresponding function based on a key signal. For example, when a key signal for channel selection is input based on a viewer's manipulation signal, the bitstream of the corresponding channel is tuned. To generate a control signal.

In addition, the detection of various viewing restrictions set by the viewer to control the operation of the satellite broadcast receiver accordingly.

The tuner and demodulator 20 tunes a broadcast signal of a channel corresponding to a control signal for tuning from the microcomputer 30 among the bitstreams received from the satellites, which are not shown, and then, the bitstreams. The demodulation is provided to the MPEG decoder 40, and the OSD unit 70 provides the MPEG decoder 40 with data on various menu screens based on the control signal of the microcomputer 70.

Accordingly, the MPEG decoder 40 separates and decodes a broadcast signal provided from the tuner and the demodulator 20 into an audio signal, a video signal, and various program information, and provides the decoded signal to the signal processor 50, and the OSD unit 70. Data for various types of information provided from) is also provided to the signal processor 50 after a predetermined signal processing process.

The signal processing unit 50 converts the digital video signal in units of frames provided after being decoded from the MPEG decoder 40 into an NTSC or PAL signal and displays it on a monitor (not shown), and the digital audio signal decoded from the MPEG decoder 40. Is converted into an analog signal and output to a speaker not shown.

In the satellite broadcasting receiver configured as described above, when the user sets the viewing time limit to 'PM 22:00 to AM 02:00' through the key input unit 10 to limit the viewing time for another specific user, The viewing time limit information is stored in the memory unit 60 by the microcomputer 30.

In the state in which the viewing time limit is set through the above-described process, the microcomputer 30 compares the current time of the counter (not shown) with the time set in the memory unit 60. When the viewing time limit set in the unit 60 is reached, an output cutoff signal is generated in the signal processing unit 50 to block the output of the video signal, and then the OSD unit 70 is driven to provide a guide message for the viewing time limit (for example, For example, 'View timed out' is displayed on the monitor.

On the other hand, in general satellite broadcasting receivers, each user registers each ID, and when the power is turned on, the user can input his or her ID and corresponding password or select a general viewing method without inputting an ID. The user can set the parental control function as described above using his ID.

Therefore, the microcomputer 30 checks the ID and password input by the user when the satellite broadcasting receiver is turned on after the viewing time limit is set as described above, and compares it with the ID of the user who sets the viewing time limit. .

As a result of the check at this time, the microcomputer 30 outputs an output cutoff signal to the signal processing unit 50 even if the current time of the timer (not shown) matches the viewing time limit set in the memory unit 60. It does not occur.

That is, the microcomputer 30 does not limit the viewing time when the current viewing user of the user who sets the viewing time limit matches, and does not input another user or ID other than the user who sets the viewing time limit. Only the general user will limit the viewing at the set time.

On the other hand, in order to set the viewing restriction according to the type of program (for example, entertainment program, movie, drama, etc.) for another specific user, the program type through the key input unit 10 with reference to a menu screen of a predetermined form. If the limit is limited, the microcomputer 30 stores the program type input by the user in the memory unit 60.

On the other hand, the information on the type of the above-described program is included in the program information embedded in the satellite broadcast signal and is provided to the microcomputer 30 from the demodulator not shown.

Therefore, as described above, the microcomputer 30 determines whether the type of the broadcast program of the channel selected by the user matches the parental control program set in the memory unit 60 while the program type is stored in the memory unit 60. If it is checked, if the check result matches the type of the parental control program set in the memory unit 60, the user who sets the parental control according to the current viewer and the program type in the same manner as in the above-described parental control method To check for a match.

Similarly, only when the users do not coincide with each other, the microcomputer 30 generates an output cutoff signal to the signal processing unit 50 and drives the OSD unit 70 to display a guidance message (eg, 'viewing') for the parental control program. It is limited program ') to display on the monitor to limit viewing by program type.

FIG. 2 is a flowchart illustrating a process for performing a parental control method of a satellite broadcasting system according to an exemplary embodiment of the present invention. Referring to the drawings, the parental control method of the satellite broadcasting receiver according to the present invention will be described below. Same as

First, referring to FIG. 2A, a limiting method according to a viewing time of a satellite broadcasting receiver is set by the user. A viewing restriction for a specific time zone is preset by the user, so that information about the viewing time limit and the setter ID is stored in the memory unit 60. When the satellite broadcasting receiver is turned on after the state stored in step 101, the microcomputer 20 checks whether the viewer ID is input (step 103), and the inputted viewer ID is temporarily stored in the memory unit 60. Saved (step 105).

Then, it is checked whether the current time of the timer (not shown) is included in the viewing time limit set in the memory unit 60 (step 107). If the current time does not correspond to the viewing time limit, the microcomputer 30 checks. The broadcast signal of the channel selected by the user is tuned by the control of the channel, and is displayed on a monitor (not shown) after performing a predetermined signal processing process (step 109), and the above-described step 107 is repeatedly performed.

If the current time corresponds to the viewing time limit in step 107 described above, referring to the viewer ID input in step 103 above, it is checked whether the current viewer matches the user who has set the viewing limit. (Step 111), if the viewer and the user who set the parental level match, the broadcast signal of the currently tuned channel is displayed (step 113), but if it does not match, i.e. In the case of (viewing restriction ID), the output of the broadcast signal of the channel tuned by the microcomputer 30 is cut off (step 115), and the OSD unit 70 is driven to output a predetermined guide message to the viewer. A notification that the viewing timeout is set (step 117).

2B is a flowchart illustrating a process of performing a parental control method according to a program type according to another embodiment of a parental control method of a satellite broadcasting receiver according to an embodiment of the present invention. Referring to FIG. The explanation is as follows.

If the parental control program for a particular program is preset by the user and the type and setter ID for the parental control program are stored in the memory unit 60 (step 201), the satellite broadcasting receiver is powered on. 20 checks whether a viewer ID is input (step 203), and stores the input viewer ID in the memory unit 60 (step 205).

Then, the broadcast control signal of the channel selected by the viewer is tuned to the tuning control signal of the microcomputer 30 (step 207). At this time, the information on the type of the program is input by the microcomputer 30 from the program information included in the general satellite signal. It reads (step 209), and compares the type of the read program with the type of the parental control program set in the memory unit 60 (step 211).

As a result of the comparison in the above-described steps, if the currently tuned program does not correspond to the viewing restricted program set by the user, the tuned channel is displayed on the monitor (step 215), and if the currently tuned program corresponds to the viewing limited program In operation 213, the microcomputer 30 detects whether the current viewer matches the user who has set the parental level by referring to the viewer ID input in step 203.

As a result of the detection, when the current viewer and the parental level setting user match each other, the currently tuned channel is continuously displayed (step 215), and when it does not match, the output of the broadcast signal is cut off (step 217), and a guidance message is displayed. The display on the monitor informs the viewer that the parental level is set (step 219).

Therefore, in the satellite broadcasting receiver, viewing can be restricted for some users according to the broadcasting time and the type of program.

As described above, according to the present invention, by limiting viewing of the satellite broadcasting receiver by time and program, it is possible to prevent harmful programs from being viewed by teenagers, thereby improving the function of the product.
