First, the display system according to the present invention is connected to the image reproducing apparatus 10 for providing image data and the image reproducing apparatus 10, as shown in Figure 1, the image data provided from the connected image reproducing apparatus It is configured to include a display device 100 for receiving and displaying.

In addition, the video playback apparatus 10 includes a first video playback apparatus, a second video playback apparatus, and a third video playback apparatus, which may include a game machine, a set-top box, a DVD player, a PC, and the like. The display device 100 is connected with the DVI or HDMI interface to provide various data to the display device.

The video reproducing apparatus 10 may be connected to each port of the display apparatus 100, and a plurality of video reproducing apparatuses may be connected to one port to perform a corresponding operation according to a switch operation control. It can also be done.

The display apparatus 100 is connected to the image reproducing apparatus 10 and serves to display image data provided from the connected image reproducing apparatus.

The detailed operation of the display apparatus is as follows.

The display apparatus may include a key input unit 110 for receiving a request command from a user, a memory unit 120 storing a viewable grade set by the user, image data provided from the image reproducing apparatus 10, and A media interface unit 130 for receiving time-based audience rating information of image data, an image processor 140 for signal processing to display image data received through the media interface unit 130, and the signal-processed image. The display unit 150 for displaying data, the menu screen generator 160 for generating a menu screen for setting and changing the viewable grade, and the hourly viewing of image data provided through the media interface unit 130. Analyze the grade information, and accordingly the grade information of the provided image data based on the viewable grade previously stored in the memory unit 120. It is configured to include a control unit 170 for controlling the production.

Referring to the operation of the display device configured as described above is as follows.

The media interface unit 130 is connected to the image reproducing apparatus 10 to receive image data provided from the connected image reproducing apparatus 10 and viewing time information of the image data.

Here, the media interface unit 130 may include HDMI. The HDMI is a new digital interface based on DVI, which is a format that integrates video and audio signals into one digital interface. Used for A / V equipment such as boxes.

These HDMIs support standard, extended or HD video as well as standard-multi-channel audio signals, and a single terminal can transmit uncompressed digital video signals up to 6 gigabytes per second to the display.

In addition, HDMI consists of three independent communication channels, such as Transition Minimized Differential Signaling (TMDS), Display Data Channel (DDC), and Consumer Electronics Control (CEC), which enable A / V data, device information, and control commands. Can send and receive

In particular, the CEC is an additional protocol for performing high-level control functions in the HDMI, and can be used in a small transmission speed and a small memory environment.

In addition, the rating information generally provided is information indicating an available age range of the video data, for example, 'all-viewers', '12 -year-old', '15 -year-old ', '18 -year-olds' 'Ratings exist.

However, the audience rating information is reference audience rating information determined based on the entire region of the corresponding video data, and details of the image data include portions that deviate from the determined audience rating.

That is, even though the viewing grade of the provided image data is '15 -year-old spectator ', looking at the details of the image data, there is a section that is inappropriate for the 15-year-old to watch.

Accordingly, the present invention provides not only the reference rating rating which is set as the average of the rating information of the image data as a whole, but also the rating information for each time according to the total running time of the video material.

For example, assuming that the total amount of the image data is 1 hour, '1-5 minutes = 13 years old audience', '5-20 minutes = 15 years old audience', 20-25 minutes = 18 years old or more '. .. '55 ~ 60 minutes = all audiences' can provide the rating information by the hour, according to the viewing rating information according to the time of the corresponding video data can perform the viewer restriction function more efficiently Make sure

The key input unit 110 is a means for receiving a desired command from a user, and may be, for example, a local key provided in a remote controller or a display device.

The memory unit 120 stores information according to the viewable grade set by the user. The memory 120 is a ROM that allows a user to modify contents in the memory, and is preferably an EEPROM that can be repeatedly erased or rewritten using a voltage higher than normal. In addition, the memory 120 may be replaced with a ROM and a switch inside the controller 170.

The viewable grade is information for limiting the user's indiscriminate viewing of the image and performs skip or screen blank of the image data exceeding the set viewable grade.

The menu screen generation unit 160 generates a menu screen for performing the viewable grade setting or the set viewable grade change. The menu screen may be generally generated in the form of an OSD (On Screen Display).

The received image data is processed by the image processor 140 and displayed on the display 150. In this case, the image processor 140 includes an MPEG-2 decoder and a scaler (not shown) for converting the video data to fit the vertical frequency, resolution, aspect ratio, etc., according to the output standard of the display 150.

In addition, the display unit 150 may be applied to various types of display modules such as digital light processing (DLP), liquid crystal display (LCD), plasma display pannel (PDP), and the like.

In this case, the controller 170 controls the reproduction of the image data based on the time-of-view rating information of the image data.

That is, the controller 170 analyzes the hourly rating information received through the media interface 130, and compares the analyzed hourly rating information with the viewable rating information previously stored in the memory 120. According to a result of the comparison, a skip signal is output or a specific black signal is displayed for a section deviating from the viewable grade set by the user among the image data.

In other words, if the viewable grade set by the user is '15 years old 'and the standard viewing grade information of the image data is '15 years old viewer', the image data will be played as it is without viewing restriction.

However, even if the image data is '15 -year-old spectator ', there will be a part that deviates from the '15 -year-old spectator' in the detailed section, and search for this through the provided hourly rating information, and for the searched specific section A skip signal is output so that the specific section is not reproduced.

As such, the controller 170 may analyze the hourly viewing rating information, compare the analyzed hourly rating information with the viewable rating information, and selectively control the playback of the provided video data. The stored viewable grade information may be transmitted to the device 10 so that only image data that is currently viewable by the user can be provided from the image reproducing apparatus.

That is, when the image reproducing apparatus is connected, the control unit 170 extracts the viewable grade previously stored in the memory unit 120 and transmits it to the image reproducing apparatus.

Then, the image reproducing apparatus compares the delivered viewable information with time-of-view rating information of the image data, and thus provides only the image data which does not deviate from the viewable information to the display apparatus 100.

That is, only a section that is currently viewable by the user is selectively provided to the display apparatus, and a section that does not meet the viewable grade is skipped by itself and the corresponding portion is not transmitted to the display apparatus.

As described above, the display apparatus according to the present invention provides information on time-based viewing ratings of image data, so that a user can check at a glance which section of the video contains violent or sensational content, and accordingly, a viewing restriction function for each time zone of the image is provided. This can effectively limit the indiscriminate viewing of adolescents or children.

In the image reproducing method of the display device according to the first embodiment of the present invention configured as described above, as shown in FIG. 2, first, a viewable grade is set (S10). That is, a menu screen for setting the viewing grade is displayed according to a command input through the key input unit 110, and the viewing grade is set on the displayed menu screen.

Subsequently, the set viewable grade is stored (S20).

In operation S30, it is determined whether the connection of the image reproducing apparatus is recognized.

Subsequently, when it is recognized that the connection of the image reproducing apparatus is detected (S30), the image data provided from the image reproducing apparatus and the time-class viewing rating information of the image data are received (S40).

Then, the rating information of each time of the received image data is analyzed (S50).

Subsequently, time-based viewing grade information of the analyzed image data and the previously stored viewable grade information are compared (S60).

In operation 70, it is determined whether there is a section having time-based viewing grade information that is out of the viewable grade in reproducing the provided image data (S70).

Subsequently, if there is a section that deviates from the viewable grade, that is, the skip signal is output for the section that deviates from the viewable grade (S80).

In addition, if there is no section that deviates from the viewable grade, that is, the image data is normally reproduced for the section that does not deviate from the viewable grade (S90).

In addition, in the image reproducing method of the display apparatus according to the second embodiment of the present invention configured as described above, as shown in FIG. That is, a menu screen for setting the viewing grade is displayed according to a command input through the key input unit 110, and the viewing grade is set on the displayed menu screen.

Subsequently, the set viewable grade is stored (S110).

In operation S120, it is determined whether the connection of the image reproducing apparatus is recognized.

Subsequently, when the connection of the image reproducing apparatus is recognized (S120), the stored viewable grade is transmitted to the connected image reproducing apparatus (S130).

In addition, the viewable ratings of the transmitted viewable information are compared with time-based viewing ratings of the corresponding video data.

Subsequently, it is determined whether there is a section of the viewing rating that is out of the viewable rating according to the comparison result (S150).

Subsequently, if a section deviating from the viewable grade exists in the determination result (S150), the section is skipped and not provided to the display apparatus (S160).

In addition, the determination result (S150) for the section that does not deviate from the viewable grade normally provides the corresponding image data to the display device (S170).

Subsequently, the display apparatus reproduces the provided image data (S180).

As described above, the display device and the image reproducing method according to the present invention provide information on the time-of-view of the image data, so that the user can check at a glance which section of the image contains violent or sensational content. By restricting the viewing function for each person, it is possible to effectively limit the indiscriminate viewing of adolescents or children.
