Display unit 16 for displaying video corresponding to broadcast signal 25 extracted by tuner 12, and OSD (On Screen Displa y), the remote controller (abbreviation of remote controller) 19 for receiving the operation signal 28 by infrared rays or the like, and converting the received operation signal 28 into data and giving it to the MPU 14 The receiving unit 18 is composed of a plurality of LEDs emitting different colors, and an indicator 20 that notifies the user of the television state by blinking, a synthesizing unit 21 that synthesizes audio data, and outputs audio based on the audio data synthesized by the synthesizing unit 21 And a memory card drive 23 that reads data and programs from the memory card 60. In the case of the present embodiment, in the television shown in FIG. 1, devices excluding the display unit 16 constitute one control device.

  The MPU 14 has a timer 41 therein. When the current time according to the XDS information 26 is acquired, the timer 41 has a function of setting the current time and measuring the current time.

  The NTSC decoder 13 has an XDS analyzer 31. The XDS analyzer 31 receives the broadcast signal 25, extracts information superimposed on a predetermined period (for example, the 21st horizontal scanning period of the video signal 27), and converts it into XDS information 26 of digital information indicating the extraction result. And output to the MPU 14. The XDS information 26 indicates the extracted information when the information superimposed on the broadcast signal 25 can be extracted, but indicates the information when it cannot be extracted.

  An operation panel for the user is provided on the main surface of the remote controller 19. On the operation panel, a cursor key 91 that is operated to move a cursor, which will be described later on the display unit 16, to move left and right or up and down on the screen, a numeric keypad 92 that is operated to directly specify a desired channel, and an operation A determination key 93 operated to determine the contents is provided. The type of keys provided on the remote controller 19 is not limited to this.

  A channel map 51 is stored in the memory 15. In the channel map 51, all channel numbers corresponding to broadcast signals receivable via the antenna 11 of FIG. 1 are registered. The memory 15 is also a device that stores information (a rating in the case of this embodiment) representing either the type of video to be displayed and the type of video forbidden to be displayed.

  This television is realized by computer hardware and software executed by the MPU 14. Generally, such software is stored and distributed in a recording medium such as the memory card 60, read from the recording medium by the memory card drive 23 or the like, and temporarily stored in the memory 15. Further, it is executed by the MPU 14. The computer hardware itself is general. Therefore, the most essential part of the present invention is software recorded on a recording medium such as the memory card 60.

  Referring to FIG. 2, the program executed on the television executes the following control regarding the comparison of ratings.

  In step 100 (hereinafter step is abbreviated as S), the antenna 11 receives a broadcast signal. When the broadcast signal is received, the tuner 12 selectively extracts one of the broadcast signals received by the antenna 11 (in the present embodiment, the broadcast signal 25 corresponding to a predetermined channel). When the broadcast signal 25 is extracted, the XDS analysis unit 31 of the NTSC decoder 13 includes information on the type of video represented by a part of the extracted signal (that is, a rating) from the extracted signal that is the broadcast signal 25 extracted by the tuner 12. XDS information 26) is extracted. When the XDS information 26 is extracted, the XDS analysis unit 31 outputs the XDS information 26 to the MPU 14. When the XDS information 26 is output, the MPU 14 checks the rating of the broadcast signal 25 based on the XDS information 26. Originally, the rating of a broadcast signal changes over time even during a live broadcast. In practice, the rating of the broadcast signal is unified for each program.

  In S102, the MPU 14 determines whether or not the rating stored in advance in the memory 15 matches the rating transmitted through the broadcast signal 25. Thereby, the MPU 14 compares the XDS information 26 extracted by the XDS analysis unit 31 with the information stored in the memory 15 to determine whether or not the broadcast signal 25 extracted by the tuner 12 represents a type of video that prohibits display. Will be judged. If it is determined that the ratings match (YES in S102), the process proceeds to S104. If not (NO in S102), the process proceeds to S108.

  In S <b> 104, the processing unit 17 stops the signal to be displayed on the display unit 16 under the control of the MPU 14. As a result, when the broadcast signal 25 extracted by the tuner 12 represents a type of video that is prohibited from being displayed, the processing unit 17 outputs the broadcast signal (video signal 27 in this embodiment) from the output terminal of the NTSC decoder 13. Will be stopped. In addition, the processing unit 17 stops the display by the display unit 16 when the broadcast signal 25 extracted by the tuner 12 represents a video of a type for which display is prohibited. Thereby, the display part 16 becomes a black screen.

  In S106, the MPU 14 performs processing such as blinking the indicator 20. In the case of the present embodiment, the MPU 14 repeats lighting the indicator 20 for 1 second after blinking for 3 seconds. As a result, the indicator 20 outputs information when the broadcast signal 25 extracted by the tuner 12 represents a type of video that is prohibited from being displayed.

  In S108, NTSC decoder 13 causes its output terminal to output the broadcast signal (actually video signal 27) extracted by tuner 12 to display unit 16. The display unit 16 displays a video corresponding to the video signal 27.

The operation of the television based on the above structure and flowchart will be described.
The MPU 14 checks the rating of the broadcast signal 25 received by the antenna 11 and extracted by the tuner 12 (S100). When the rating is checked, the MPU 14 determines whether or not the rating stored in advance in the memory 15 matches the rating sent through the broadcast signal 25 (S102). If it is determined that the ratings match (YES in S102), the processing unit 17 sets the display unit 16 to a black screen under the control of the MPU 14 (S104). When the display unit 16 becomes a black screen, the MPU 14 performs processing such as blinking the indicator 20 (S106). In this case, it is desirable that the instruction manual describes that the indicator 20 blinks when the ratings match.

  As described above, when the rating value matches the preset value, the television according to the present embodiment performs processing such as setting the display unit to a black screen and blinking the indicator. Thus, the user can easily know that a video that the user does not want to watch is being broadcast even if a message such as “protected program by TV-Y” is not displayed on the TV screen. Since it is easily known, it is not necessary to display a message such as “protected program by TV-Y”. As a result, it is possible to provide a television capable of easily notifying why an image is not displayed while preventing an image that should not be displayed from being displayed.

  As a modified example, in S106, the combining unit 21 controls the MPU 14 while the indicator 20 is blinking and the display unit 16 is in a black screen, “Please switch the channel” or “No failure”. The voice data of the message such as may be synthesized. In this case, the speaker 22 outputs sound based on the sound data synthesized by the synthesis unit 21. Thereby, the synthesis unit 21 and the speaker 22 are devices that output information using sound (in this case, sound representing the mouth). The time when the sound is output may be while the indicator 20 is blinking or after the blinking of the indicator 20 is finished. By outputting audio, it is not necessary to display a message such as “protected program by TV-Y”, and the user's surprise that the video is not displayed can be eased. In this case, based on the selection set in advance in the MPU 14, the synthesizer 21 may create the voice data of the message using any of different languages such as English, Spanish, and French.

  As a modification, in S106, the composition unit 21 synthesizes music data for calming the user's psychology while the indicator 20 is blinking and the display unit 16 is a black screen under the control of the MPU 14. May be. In this case, the speaker 22 outputs music based on the data synthesized by the synthesis unit 21. Thereby, the synthesis unit 21 and the speaker 22 are devices that output information using sound (in this case, sound representing music). The music that can be output includes various songs. Examples of such music include “humoresque”. The music that is desired to be output is music that relaxes the user's psychology. By outputting music that relaxes the user's psychology, messages such as “protected program by TV-Y” need not be displayed, and the user's surprise and disappointment that the video is not displayed can be eased. . The effect of relieving the user's surprise and disappointment is the basis of the effect of increasing the user's satisfaction with the television as a product and reducing the complaint.

  As a modified example, in S106, the indicator 20 may be lit in either a unique color or a lighting pattern when the ratings match. As a result, it is possible to notify the user that the ratings match without providing an OSD or the like.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
