Not shown), it may be provided in the main body of the display device by wire.

The tuner 10 tunes the broadcast signal received through the antenna 1 into a broadcast signal having a frequency band corresponding thereto according to the control signal of the controller 50. That is, the tuner 10 tunes only a broadcast signal corresponding to a channel broadcast through the broadcast output unit 30 among the plurality of broadcast signals received through the antenna 1 and outputs the broadcast signal to the processor 20. In this case, the tuned broadcast signal preferably includes rating information of a broadcast program based on the broadcast signal.

Table 1.

Here, the data processor (not shown) may be included in the controller 50, and the role of the data processor (not shown) will be described as the role of the controller 50.

In addition, the processor 20 processes the sound signal separated by the demultiplexer 24, converts the sound signal into an analog signal, and outputs the sound signal to the sound output unit 32 and the image output from the demultiplexer 24. The image processing unit 28 converts the signal into a signal in a format that the display unit 34 can display and provides the signal to the display unit 34, and an OSD generation unit 29 for generating a predetermined OSD screen. In particular, the sound processing unit 26 may perform signal processing such as sound equalizer, mono, stereo, surround, echo, etc. under the control of the control unit 50, and a predetermined mute sound (mute), a single sound, The previously stored melody may be output through the sound output unit 32.

Here, the OSD generation unit 29, a mute screen (black screen) or a blue screen for muting the image so that the image of the broadcast program is not displayed through the broadcast output unit 30 under the control of the control unit 50 It is desirable to produce.

The control unit 50 includes a microcomputer 55 and a memory 53.

The microcomputer 55 sets / stores the viewing restriction rating information input by the user's input operation through the user input unit 40 in the memory 53. In addition, the microcomputer 55 determines whether the user sets the parental control function on or off by operating the user input unit 40 or a user adjustment menu (not shown), and sets the on / off setting state of the parental control function. It stores in the memory 53.

The microcomputer 55 determines whether a channel switch is input through the user input unit 40 and based on the on / off setting state of the parental control function stored in the memory 53 when the channel switch is input. It is determined whether the parental level is on. If it is determined that the parental level control function is set to ON, the microcomputer 55 controls the tuner 10 to tune the broadcast signal of the channel to which the switching is selected.

At this time, the microcomputer 55 controls the tuner 10 to tune the broadcast signal of the channel selected for switching, and at the same time, a predetermined standby screen is displayed through the display unit 34 and a predetermined sound output unit through the sound output unit 34. The processor 20 controls the standby sound of the output. Here, the predetermined standby screen includes at least one of a mute screen, a blue screen, and a pre-stored capture screen, and the predetermined standby sound includes a mute sound (mute), a single note, and a pre-stored melody. It is preferable to include at least one of them. In the following description, the mute screen (black screen) is displayed on the predetermined standby screen, and the mute sound is output by the predetermined standby sound. Accordingly, the microcomputer 55 controls the tuner 10 and simultaneously controls the OSD generator 29 to display the mute screen on the display 34, and mutes the sound through the sound output unit 34. Control the sound processing unit 26 to be output.

As such, in the state where the image and sound through the broadcast output unit 30 are muted, the microcomputer 55 controls the processing unit 20 to process the tuned broadcast signal, and in the process of processing the tuned broadcast signal, the demultiplexer ( 24) receives the data information, and extracts rating information of a broadcast program based on the broadcast signal from the PMT information of the data information.

Accordingly, the microcomputer 55 compares the extracted rating information with the preset parental control rating information stored in the memory 53 to determine whether the broadcast program based on the broadcast signal of the switched channel is a parental control program. . That is, the microcomputer 55 compares the rating information with the parental level rating information and determines that the broadcast program is a viewable program when the rating information is less than or equal to the parental level rating. If it is determined that the broadcast program of the tuned broadcast signal is a program that can be viewed, the microcomputer 55 cuts the mute screen and the mute sound output, and the image and sound of the broadcast program according to the tuned broadcast signal are output to the broadcast output unit. The image processor 28, the sound processor 26, and the OSD generator 29 are controlled to be broadcasted through the device 30.

Here, the microcomputer 55 compares the rating information with the parental level rating information, and determines that the broadcast program is a limited viewing program when the rating information is not less than the parental level rating. If the microcomputer 55 determines that the broadcast program of the tuned broadcast signal is a viewing restricted program, the microcomputer 55 controls the image processor 28, the sound processor 26, and the OSD generator 29 to control the mute screen and the mute sound. Keep the output.

Accordingly, the display device of the present invention outputs a mute screen and a mute sound through the broadcast output unit 30 as soon as the channel switching is input, when the viewing restriction function is turned on when the channel switching is input, The mute screen and the mute sound output may be maintained or the provided broadcast program may be broadcast depending on whether the broadcast program provided through the switched channel is a parental control program. As described above, the display apparatus according to the present invention blocks broadcasts at the time of channel switching in a state in which the parental control function is set to on, so that when the broadcast program of the switched channel is a viewing-limited program, the broadcast is muted for a while before being muted. The conventional problem of broadcasting a broadcast program can be prevented.

Here, the above description of the present invention with reference to FIG. 1 illustrates a display device including a display unit 34 and a sound output unit 32 as the broadcast output unit 30 as an embodiment. However, in the configuration of FIG. 1, the display unit 34 and the sound output unit 32 are separated into separate devices (not shown), and the broadcast output unit 30 separates the image and sound from the separate devices (not shown). It can also provide as a port part (not shown) to provide. That is, when the broadcast output unit 30 includes a port unit (not shown) that provides an image and sound as a separate device (not shown), the configuration of FIG. 1 is an embodiment of a broadcast processing device such as a set-top box. . That is, the configuration of the present invention for more effectively and reliably executing the parental control function is an integrated type including a broadcast processing device such as a set-top box, a function of the set-top box, and a display unit 34 and a sound output unit 32. It goes without saying that the present invention can be applied to any of the display devices (the configuration of Fig. 1).

The control flow of the display apparatus according to the present invention having such a configuration will be described below with reference to FIG. 2. First, in the memory 53, parental control rating information (eg, V-16) set according to a user's input through the user input unit 40 is stored, and the on / off setting state of the parental control function is stored.

The microcomputer 55 determines whether channel switching is input through the user input unit 40 (S10). When the channel switch is input, the microcomputer 55 determines whether the parental control function is on based on the on / off setting state of the parental control function stored in the memory 53 (S20). If the parental control function is turned off, the microcomputer 55 controls the tuner 10 to tune the broadcast signal of the channel selected for switching (S25), and the image and sound of the broadcast program according to the tuned broadcast signal are adjusted. The processing unit 20 is controlled to be transmitted through the broadcast output unit 30 (S80).

 Herein, if it is determined in step S20 that the parental level is on, the microcomputer 55 controls the tuner 10 to tune the broadcast signal of the channel selected for switching (S40). At this time, the microcomputer 55 controls the tuner 10 to tune the broadcast signal of the switched channel (S40), and at the same time, a mute screen is displayed through the display unit 34 and muted through the sound output unit 34. The processor 20 is controlled to output a sound (S30). Accordingly, the user may feel that the broadcast output through the broadcast output unit 30 is muted at the same time as the channel switching input.

As such, in a state in which the image and sound output through the broadcast output unit 30 are muted, the microcomputer 55 controls the processor 20 to process the tuned broadcast signal, and the microcomputer 55 selects the tuned channel. In the process of processing the broadcast signal, data information received together with the broadcast signal is received from the demultiplexer 24, and the rating information of the broadcast program based on the broadcast signal is extracted from the PMT information of the data information (S50). Accordingly, the microcomputer 55 compares the extracted rating information with the parental control rating information previously stored in the memory 53 to determine whether the broadcast program based on the broadcast signal of the switched channel is a parental control program. That is, the microcomputer 55 compares the rating information with the parental level rating information and determines whether the rating information is less than or equal to the parental level rating (S60). If the rating information (eg, V-13) is less than or equal to the parental control rating (eg, V-16), the microcomputer 55 blocks the mute screen and the mute sound output (S70), and the tuned broadcast signal. The image processor 28 and the sound processor 26 and the OSD generator 29 are controlled to broadcast the image and sound of the broadcast program through the broadcast output unit 30 (S80).

Herein, when it is determined in step S60 that the rating information (eg, V-19) is not less than or equal to the parental control rating (eg, V-16), the microcomputer 55 broadcasts the tuned broadcast signal. The program is judged to be a limited viewing program, and the video and sound are muted.

Thus, the control method of the display apparatus according to the present invention, when the channel switching is input when the parental control function is set on, by blocking the broadcast immediately output, when the broadcast program of the switched channel is a viewing limited program broadcast The conventional problem of broadcasting the broadcast program for a while before the broadcast can be prevented.

Although some embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that modifications may be made to the embodiment without departing from the spirit or spirit of the invention. . It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.

As described above, according to the present invention, when switching channels, by blocking the broadcast in advance before the broadcast is blocked by the parental control function, the display device can effectively protect the viewer by blocking the broadcast program restricted viewing and A control method of the display device and a broadcast processing device can be provided.
