[0017]
Next, the operation of the DVD player will be described with reference to the drawings.
When the parent plays and listens to the DVD 1 on which the child has recorded the movie, if there are many violent scenes and it is known that imitating it is not good, a warning display is set in advance.
First, after setting the DVD 1 on the tray, the menu key of the remote controller 13 is operated to display the menu on the screen 11 a of the monitor 11.
Then, when “Warning time setting” is selected from the menu items, the control unit 15 shifts to the warning time setting mode in response to this.
Subsequently, when the parent operates the play key, the control unit 15 causes the DVD 1 to start reproducing information. Accordingly, when the data in the TOC area is read, the control unit 15 assigns unique identification information to the DVD 1 and stores it in the memory 15a.
[0018]
When the violence scene starts after the movie is displayed on the screen 11a by the reproduction start, the parent operates the time setting key once.
When the time setting command is input, the control unit 15 stores the time data read from the recording track at that time in the memory 15a in association with the identification information of the DVD1.
When the parent operates the time setting key again when the violence scene ends, the time data read from the recording track at that time is stored in the memory 15a.
After this, the parent continues to operate the time setting key as the violence scene starts, and when all the reproduction is completed, a plurality of warning start and end time data required only for this DVD 1 are stored. become.
[0019]
Next, when the child wants to watch the movie of DVD1, after setting the DVD1 on the tray and operating the play key of the remote controller 13, the control section 15 starts the information reproduction of the DVD1.
Along with this, when the recording information of the DVD 1 is read and sent to the control unit 15, each circuit is operated to display a movie on the screen 11 a of the monitor 11. The control unit 15 searches the data in the memory 15a and determines whether the unique information indicating the DVD 1 matches the identification information recorded in advance.
If they match, it is further determined whether or not time data is recorded on the DVD 1. If time data is recorded, the input time data is compared with the time data in the memory 15a.
Then, when the two match, the display operation of the OSD circuit 15b is started, and the character data of the warning sign stored in the memory 15a is transmitted.
[0020]
Upon receiving this character data, the OSD circuit 15b displays “Do not imitate!” On the screen 11a of the monitor 11 as shown in FIG. Is enlarged.
Since this character is displayed when the violence scene begins to appear, it can warn the child that he or she should not imitate.
In addition, since the violence scene continues to be projected as it is, it is possible to acquire a judgment of what should not be imitated specifically.
Thereafter, when the time data is input, the control unit 15 checks the time data in the memory 15a and stops the display operation of the OSD circuit 15b when the time data matches.
As a result, the warning character disappears from the screen 11a and only the movie is displayed again. If time data is input during this video display, the screen 11a is displayed again with the message "Do not imitate!" Is displayed.
Thereafter, when the time data is input again, the display operation of the OSD circuit 15b is stopped, and the warning character is erased from the screen 11a.
Such operations and display are repeated, and when the reproduction is completed, a series of operations is stopped.
[0021]
In the above-described embodiment, the time zone in which the parent operates the time setting key while watching the reproduced video to set the time zone in which the warning is to be displayed is set in advance, but the warning is displayed when the parent and the child are watching together. May be.
At this time, after setting the DVD 1 to be reproduced on the tray, the play key of the remote controller 13 is operated. Accordingly, when the information is reproduced and the image is displayed on the screen 11a of the monitor 11, when the violence scene starts, the time setting key is operated.
Then, since a warning display start command is output, the control unit 15 starts the display operation of the OSD circuit 15b and sends out the character data of the warning sign stored in the memory 15a.
Therefore, the screen 11a of the monitor 11 displays "Do not imitate!" Is enlarged.
Thereafter, when the time setting key is operated in accordance with the end of the violence scene, the control unit 15 stops the operation of the OSD circuit 15b, so that the warning character on the screen 11a disappears. By repeating such an operation and display, it is possible to notify a scene that a child should not imitate while watching a movie together.
[0022]
By the way, the warning display can be set only by inputting the movie title in advance without using the time setting key as described above.
That is, in the TOC area of the DVD 1, address data corresponding to elapsed time information from the first chapter of the title number 1 is recorded.
Therefore, if the title number including the violence scene is known, it may be input.
In this case, after setting the DVD 1, menu items are displayed on the screen 11a of the monitor 11 by remote control operation, and "warning title setting" is selected from the menu items.
When the screen for inputting the title and the chapter number is input, the cursor is moved to a predetermined position, and the chapter number is input after the title number by operating the ten keys.
When this number data is transmitted, the control unit 15 reads time information corresponding to each title number and chapter number, and stores time data indicating the start and end of a chapter of a certain title in the memory 15a. To memorize.
[0023]
The subsequent reproducing operation is as described above. When it is determined that time data is recorded on the DVD 1 at the time of starting reproduction, the control unit 15 matches the input time data with the time data in the memory 15a. At this point, the display operation of the OSD circuit 15b is started.
For this reason, when the video of the title indicating the violence scene is displayed on the screen 11a, the "do not imitate!" Is enlarged.
Thereafter, if the time data for ending the warning display in the chapter is stored, the display of the warning character is stopped at the end of the chapter.
Therefore, it is possible to warn the child not to imitate as described above.
If the title number including the violent scene is not known in advance, the title and the chapter with the violent scene may be confirmed by fast-forward reproduction, and may be input and set later as described above.
Thereby, similarly to the above, a warning can be displayed when necessary.
[0024]
【The invention's effect】
As described above, according to the first aspect of the present invention, the OSD circuit is activated when a warning display start command is issued from the key input unit or when a warning start and end time zone set in advance in the menu display. Since the display data of the warning sign is output from the, the effect of being able to display a warning prohibiting imitation in a scene unfavorable for children without changing the image being reproduced is obtained.
According to the second aspect of the present invention, the warning sign display data is output from the OSD circuit during the warning start and end times set in advance in the menu display, so that it is preferable for the child without changing the image being reproduced. There is an effect that a warning prohibiting imitation can be displayed in a scene where there is no copying.
According to the third aspect of the present invention, when reproducing a disc information, when a warning display start command is transmitted from the key input unit, the display data of the warning sign is output from the OSD circuit. There is an advantage that a warning prohibiting imitation in a scene unfavorable to children can be displayed without any loss.
According to the fourth aspect of the present invention, when a title of a display scene to be prohibited from imitating information on the disc is transmitted from the key input unit, the start and end time data of the title is stored in the memory.
