In certain cases, there is also a term arbitrarily selected in this specification, in which case the meaning will be described in detail in the description of the invention.

1 is a block diagram showing the configuration of a digital broadcast receiver constructed in accordance with the present invention.

Referring to FIG. 1, a digital broadcast receiver according to the present invention includes a tuner 101, a demodulator 102, a demultiplexer 103, a signaling information processor 104, an application controller 105, a storage 108, The external input receiver 109, the decoder / scaler 110, the controller 115, the mixer 118, the output formatter 119, and the display 120 may be configured. However, hereinafter, the digital broadcast receiver will be described using a digital television receiver (DTV) as an example. Accordingly, the digital broadcast receiver may further include other necessary components in addition to the configuration shown in FIG. 1.

The tuner 101 tunes a specific channel to receive a broadcast signal including content.

The demodulator 102 demodulates the broadcast signal input from the tuner 101.

The demultiplexer 103 demultiplexes an audio signal, a video signal, and signaling information from the demodulated broadcast signal. In this case, the demultiplexing may be performed through PID (Packet IDentifier) filtering. In addition, the signaling information will be described below using System Information (SI) information such as PSI / PSIP (Program Specific Information / Program and System Information Protocol) as an example for convenience of description.

The demultiplexer 103 outputs the demultiplexed audio signal / video signal to the decoder / scaler 110 and the signaling information to the signaling information processor 104.

The signaling information processor 104 processes the demultiplexed signaling information and outputs the demultiplexed signaling information to the application controller 105, the controller 115, and the mixer 118. Here, the signaling processor 104 may include a database (not shown) for temporarily storing the processed signaling information.

The application control unit 105 includes a channel manager 106 and a channel map 107. The channel manager 106 may form and manage the channel map 107 based on the signaling information, and control the channel map 107 to be switched based on the channel map 107 according to a user input.

The decoder / scaler 110 includes a video decoder 111, an audio decoder 112, a scaler 113, and a video processor 114.

The video decoder / audio decoders 111 and 112 receive and process demultiplexed audio signals and video signals.

The scaler 113 scales the signal processed by the decoders 111/112 into a signal of an appropriate magnitude for output.

The controller 115 determines user age information, and determines a rating level corresponding to the determined user age information.

In this case, the controller 115 may determine the user age information by using the sensing information sensed by the sensor included in the shutter glasses 121 used for 3D image recognition. The shutter glasses 121 include a pair of shutter liquid crystal panels corresponding to the left and right eyes of the user, and the shutter glasses 121 are turned on and off at a predetermined frequency. The shutter glasses 121 will be described in detail with reference to FIG. 2.

The display unit 120 outputs content, a UI, and the like. In this case, the display 120 displays a user interface corresponding to the determined rating on the display screen, wherein the user interface may include the 3D image.

In this case, the display 120 may display items corresponding to the determined rating level on the display screen.

In addition, the display 120 may display a broadcast program corresponding to the determined rating level on the display screen.

In addition, the display 120 may display thumbnail images of broadcast programs corresponding to the determined rating level on the image channel list.

In this case, the display 120 may output the user interface at an output position corresponding to the determined rating level.

If the user interface displayed on the display screen of the display unit 120 does not correspond to the determined rating, the controller 115 may tilt the user interface displayed on the display screen and display the same on the display screen.

The camera 122 is mounted on the digital broadcasting receiver to capture an image at a predetermined cycle, and the controller 115 detects the face shape information of the user from the captured image, and the user is detected by the detected face shape information. To judge the age information.

The application controller 105 may receive a key input of a user or the like through a remote controller.

In this case, the application controller 105 may further include an OSD data generator (not shown) for configuring the UI. Alternatively, the OSD data generation unit may be configured as a display unit separate from the application to generate OSD data for UI configuration under the control of the application control unit 105.

The storage unit 108 may store in advance UI data or OSD data for providing a 2D or 3D UI to be provided in response to a user's key input from an application or an OSD data generator. In this case, the storage unit 108 may store UI data or OSD data for providing a 2D or 3D UI corresponding to user age information. In addition, the storage unit 108 may store additional information related to other broadcast receivers.

The mixer 118 mixes and outputs inputs of the signaling processor 104, the decoder / scaler 110, and the application control unit 105.

The output formatter 119 configures the output of the mixer 118 according to the output format of the display unit. Here, the output formatter 119 bypasses, for example, 2D content, and processes the 3D content in 3D format according to the format and the output frequency of the display unit 120 under the control of the controller 115. Can work as a 3D formatter.

In relation to the present invention, there are two methods of displaying 3D images, a method of wearing glasses and a glasses-free method of not wearing glasses. In addition, the way of wearing glasses is divided into a passive (active) method and an active (active) method. The passive method distinguishes between a left image and a right image by using a polarization filter. Or, wearing blue and red sunglasses on both eyes is also passive. The active method is a method of distinguishing left and right eyes using a liquid crystal shutter, and distinguishing a left image and a right image by sequentially covering the left eye (left eye) and the right eye (right eye) in time. In other words, the active method is a method of periodically wearing a glasses with an electronic shutter that is periodically repeated and synchronized with the time-divided screen, also referred to as a time split type or a shuttered glass method. . Representatives known as a glasses-free method without wearing glasses include a lenticular method in which a lenticular lens plate in which a cylindrical lens array is vertically arranged in front of the image panel, and a periodic slit in the upper part of the image panel. There is a parallax barrier method having a barrier layer having a.

In the present specification, a stereoscopic method of the 3D display method is taken as an example, and an active method of the stereoscopic method is described as an example. However, hereinafter, the shutter glasses will be described as an example of the active type media, but the present invention is not limited thereto, and the present invention can be applied to other media as described below.

The output formatter 119 outputs the configured 3D image data to the display unit 120, and synchronizes the synchronized 3D image data (Vsync) with respect to the configured 3D image data so that the 3D image data is synchronized with the shutter glasses 121. ) Is generated and output to the IR emitter (not shown) in the shutter glasses so that the shutter glasses 121 can watch in synchronization with the display.

The IR emitter receives the sync signal generated by the output formatter 119 and outputs the sync signal to the light receiving unit (not shown) in the shutter glasses 121, and the shutter glasses 150 pass through the IR emitter (not shown) through the light receiving unit. By adjusting the shutter open period according to the received synchronization signal, the 3D image data output from the display unit 120 may be synchronized.

2 is a diagram illustrating a configuration of shutter glasses according to an embodiment of the present invention.

Referring to FIG. 2, the shutter glasses include a left eye shutter liquid crystal panel 200 and a right eye shutter liquid crystal panel 230. The shutter liquid crystal panels 200 and 230 perform a function of simply passing or blocking light according to the source driving voltage. When the left image is displayed on the display surface of the digital broadcast receiver, the left eye shutter liquid crystal panel 200 passes the light and the right eye shutter liquid crystal panel 230 blocks the light transmission, so that the left image is transmitted only to the left eye of the user of the glasses. To be. On the other hand, when the right image is displayed on the display surface of the digital broadcast receiver, the left eye shutter liquid crystal panel 200 blocks the light transmission, and the right eye shutter liquid crystal panel 230 passes the light, so that the right image is the right eye of the user. To be delivered only to.

In this process, the infrared receiver 160 of the shutter glasses 150 converts the infrared signal received from the digital broadcast receiver into an electrical signal and provides it to the controller 170. The controller 170 controls the left eye shutter liquid crystal panel 200 and the right eye shutter liquid crystal panel 230 to be turned on and off alternately according to the synchronization reference signal.

In addition, the position sensor 180 of the shutter glasses senses information for detecting the position of the user. The sensing information is transmitted by the infrared transceiver 160 to the digital broadcast receiver.

Meanwhile, the 3D image data may be implemented in 3D by various methods such as giving a tilt to a depth or giving a 3D effect. Hereinafter, a method of giving depth among the above methods may be used. Briefly explain.

The digital broadcast receiver processes the 3D image data using the stereoscopic principle. That is, when one object is photographed by two cameras of different positions, the left image data and the right image data are generated, and each generated image data is inputted separately so as to be orthogonal to each other in the left and right eyes of the person. It is a principle that the 3D image is generated by combining the image data inputted into the left and right eyes of the brain. In the above, the fact that the image data is arranged to be orthogonal to each other means that each image data does not interfere with each other.

FIG. 3 is a diagram illustrating perspective according to a gap or parallax (hereinafter, referred to as a gap) between the left image data and the right image data.

FIG. 3 (a) illustrates an upper position 303 in which both data are combined when the distance between the right image data 301 and the left image data 302 is narrow, and FIG. 3 (b) illustrates the right image data ( 311 and the left image data 312 have been described, the position of the upper image 313 to form.

3 (a) to 3 (b) show the degree of perspective at which different images are formed at different positions according to the interval between the left image data and the right image data in the image signal processing apparatus.

Referring to FIG. 3 (a), the upper side draws extension lines R1 and R2 facing one side and the other side of the right image data 301 to the right eye, and the left side faces the other side to one side of the left image data 302. When drawing the extension lines L1 and L2, the extension line R1 for the right image data and the extension line L1 for the left image data cross each other at a distance d1 from the right eye and the left eye at a point 303. Bears.

Referring to FIG. 3B, the image is based on the foregoing description in FIG. 3A, and the extension line R3 for the right image data and the extension line L3 for the left image data have a predetermined distance from the right eye and the left eye. at point 313 intersecting each other at d2).

Here, comparing d1 in FIG. 3 (a) and d2 in FIG. 3 (b) which show the distances from the left and right eyes to the positions 303 and 313 where the images are formed, the distance d1 is greater than the left and right eyes than d2. far. That is, the image in Fig. 3A is formed at a distance farther from the left and right eyes than the image in Fig. 3B.

This is due to the distance (east-west direction with reference to the drawing) between the right image data and the left image data.

For example, the interval between the right image data 301 and the left image data 302 in FIG. 3A is the interval between the right image data 303 and the left image data 304 in FIG. 3B. Relatively narrow compared with

Therefore, inferring based on Figs. 3 (a) and 3 (b), as the interval of each image data becomes narrower, the image formed by the combination of the left image data and the right image data appears to be far from the human eye.

4 is a diagram illustrating an example of a method of implementing a 3D UI in relation to the present invention.

4 (a) and 4 (b) are implemented as a 3D image of the UI itself including a plurality of items, in the case of Figure 4 (a) and the left image data 401 and the right image data (UI) In the case of FIG. 4B, the interval between the left image data 404 and the right image data 405 constituting the UI is wide.

Accordingly, the 3D UIs 403 and 406 implemented according to the intervals of the respective image data in FIGS. 4 (a) and 4 (b) are based on the above-described principle of FIG. 3. The image is located far from the human eye and looks far away, and the 3D UI 406 implemented in FIG. That is, by adjusting the distance between the left image data and the right image data constituting the UI, it is possible to give an appropriate depth to the UI.

Hereinafter, an embodiment of providing a user interface according to user age information in a digital broadcast receiver for providing such a 3D image will be described in detail.

5 is a diagram illustrating a process of providing a user interface according to user age information according to an embodiment of the present invention.

Referring to FIG. 5, in step S501, the digital broadcast receiver according to the present invention determines the user age information.

In this case, the digital broadcast receiver may determine the user age information by using the sensing information sensed by the position information sensor included in the shutter glasses used for 3D image recognition.

For example, the shutter glasses generate sensing information for sensing the user's location in the location information sensor and transmit the sensing glasses to the digital broadcast receiver. After receiving the sensing information, the digital broadcast receiver may apply a calculation method such as triangulation to calculate the height of the user and determine the user age information by the calculated height of the user.

In addition, according to another embodiment, the digital broadcast receiver captures an image at a predetermined period from a camera mounted on the digital broadcast receiver, detects the face shape information of the user from the captured image, and then detects the detected face shape information. The age information of the user can be determined.

In this case, after detecting the shape of the user's face in the captured image, it is possible to determine the age information of the user by comparing with the previously stored pattern. Various methods may be used as a method of detecting a user's face shape. For example, by detecting edges in an image, the user's face shape may be detected, and a comparison of previously stored patterns and edges may be used to identify the user's age. Methods and the like can be used.

In step S502, the digital broadcast receiver determines a rating class corresponding to the determined user age information. The ratings may be classified according to the embodiment. For example, the ratings may be divided into '15 years old, 17 years old, and 20 years old ', and the digital broadcasting receiver may include a plurality of ratings grouping the determined user ages. You can determine where you belong.

Next, the digital broadcast receiver displays a user interface corresponding to the determined rating class on the display screen. Since the user interface information corresponding to the plurality of rating classes may be stored in the storage unit, the digital broadcasting receiver reads the user interface corresponding to the determined rating class and displays it on the display screen.

At this time, in step S503, the digital broadcast receiver determines whether the user interface currently output on the display screen is a user interface corresponding to the determined rating.

As a result of the determination in step S503, if the user interface currently output on the display screen is not a user interface corresponding to the determined rating, the digital broadcast receiver adjusts the output user interface in step S505.

As a result of the determination in step S503, if the user interface currently output on the display screen is a user interface corresponding to the determined rating, in step S506 the digital broadcast receiver does not need to adjust the output of the user interface and the user rating. Outputs the user interface corresponding to

In this case, when the outputted user interface is not a user interface corresponding to the determined rating, the digital broadcasting receiver outputs the user interface to an output position corresponding to the rating, or tilts the user interface to the display screen. I can display it.

For example, if the user interface currently being output is not a user interface corresponding to the determined rating, the digital broadcasting receiver reads the output position corresponding to the rating in the storage unit and then moves the user interface to the read output position. And print it out.

For example, items such as a system setting, a channel setting, and a lock setting need to prevent access by a user having a low user age, so that the output position is set high so that the user's access is not easy.

In particular, in the case of a user interface implemented as a touch-type OSD among the three-dimensional user interface, the output position may be set high so that a user with a low user age cannot touch it.

6 is a diagram illustrating an embodiment of providing a user interface according to user age information according to the present invention.

Referring to FIG. 6, when the currently output user interface 601 is not a user interface corresponding to the determined user age information, the digital broadcasting receiver reads an output position corresponding to a rating level from the storage unit. The user interface is output to the read output location 602.

Therefore, the present invention can be adjusted so that the user's access is not easy by adjusting the output position of the user interface which needs to prevent the access of the user with a low user age such as system setting, channel setting, lock setting, and the like. In this case, the user interface may be composed of a 3D image, and in particular, may be a user interface implemented as a touch OSD that detects a user touch and determines whether to select it. In this case, the digital broadcasting receiver may set the output position of the user interface to be high so that a user with a low user age cannot touch it.

7 illustrates another embodiment of providing a user interface according to user age information according to the present invention.

Referring to FIG. 7, when the currently output user interface is not a user interface corresponding to the determined user age information, the digital broadcasting receiver may apply a tilt to the user interface 701 and display the same on the display screen. The user can be prevented from watching.

For example, when the user interface output on the display screen includes a broadcast program that does not correspond to the determined user age information or information about the broadcast program, the digital broadcast receiver may display a user interface 701 with a predetermined value or more. By applying the tilt angle, the readability of the user is reduced so that a younger user is not exposed to an inappropriate screen.

8 is a diagram illustrating another embodiment of providing a user interface according to user age information according to the present invention.

Referring to FIG. 8, the digital broadcast receiver of the present invention may output only items corresponding to the determined user age information to the user interface. For example, items that need to be prevented from being accessed by users of low age, such as system settings, channel settings, and lock settings, are excluded from the user interface and output.

For example, the digital broadcast receiver may output a user interface 803 configured to exclude the 'detail setting' item 802 from the user interface 801 for a user having a low user age.

9 illustrates another embodiment of providing a user interface according to user age information according to the present invention.

Referring to FIG. 9, the digital broadcast receiver of the present invention may output only broadcast programs corresponding to the rated rating. In particular, when providing a list of video channels, thumbnail images of broadcast programs corresponding to the determined rating are provided. Only these may be displayed in the image channel list 900.

Accordingly, the present invention can provide a user interface suitable for the user's age by controlling the user's interface output by recognizing the user, thereby satisfying various needs of the user.

In addition, the present invention has the effect of automatically improving the user interface output upon recognition of the user, thereby providing a user interface suitable for the user's age without going through a separate interface setting procedure to enhance user convenience.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible. Accordingly, the spirit of the present invention should be understood only by the claims set forth below, and all equivalent or equivalent modifications thereof will belong to the scope of the present invention.
