The terms used in the present invention have been selected based on the general structure of the present invention and the functions of the present invention. In certain cases, there may be a term arbitrarily selected herein, and the meaning thereof will be described in detail in the description section of the present invention.

1 is a block diagram showing a configuration of a digital broadcast receiver constructed according to the present invention.

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, An external input receiving unit 109, a decoder / scaler 110, a control unit 115, a mixer 118, an output formatter 119, and a display unit 120. Hereinafter, the digital broadcast receiver will be described as a digital television receiver (DTV) as an example. Therefore, the digital broadcasting receiver may further include other configurations aside from the configuration shown in FIG.

The tuner 101 tunes a specific channel and receives a broadcast signal including a content.

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

The demultiplexer 103 demultiplexes the audio signal, the video signal, and the signaling information from the demodulated broadcast signal. Here, the demultiplexing can be performed through PID (Packet IDentifier) filtering. For the sake of convenience, the signaling information will be referred to as System Information (SI) information such as PSI / PSIP (Program Specific Information / Program and System Information Protocol).

The demultiplexing unit 103 outputs the demultiplexed audio / 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 it to the application control unit 105, the control unit 115 and the mixer 118. Here, the signaling processor 104 may include a database (not shown) for temporarily storing the signaling information to be processed.

The application control unit 105 includes a channel manager 106 and a channel map 107. The channel manager 106 forms and manages the channel map 107 based on the signaling information, and can control the channel switching 107 and the like based on the channel map 107 according to the input of the user.

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 decoder 111/112 receives and processes the demultiplexed audio and video signals.

The scaler 113 scales the signal processed by the decoders 111/112 with a signal of a proper size for output.

The application control unit 105 includes a user input unit (not shown) for receiving a key input of a user or the like via a remote control or the like. At this time, the user input unit receives a 3D lock setting from a predetermined user interface.

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

The control unit 115 determines a three-dimensional image output from the digital broadcast receiver in response to the 3D lock setting, outputs the determined three-dimensional image as a two-dimensional image, Is not output.

The user input unit may select a 3D lock setting time in the user interface, and the controller 115 may output the determined three-dimensional image as a two-dimensional image during the selected 3D lock setting time, It is possible to control not to output the three-dimensional image.

In addition, the user input unit may select a 3D lock channel in the user interface, and the controller 115 may output a three-dimensional image received in the selected 3D lock channel as a two-dimensional image, It is possible to control not to output the three-dimensional image.

At this time, the control unit 115 may output a list for distinguishing the 3D lock channel.

In addition, the user input unit may select a broadcast program to be 3D-locked on the user interface, and the controller 115 may output a three-dimensional image of the selected broadcast program as a two-dimensional image, Can not be outputted.

In this case, the user interface is an electronic program guide, and the electronic program guide can separately display the 3D programs to be locked.

The display unit 120 outputs contents, UI, and the like.

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

The output formatter 119 configures the output of the mixer 118 in accordance with 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 its format and the output frequency of the display unit 120 under the control of the control unit 115 It can operate as a 3D formatter.

In connection with the present invention, there are two methods of displaying three-dimensional images: a method of worn glasses and a method of non-wearing glasses. In addition, the manner of wearing glasses is divided into a passive mode and an active mode. The passive method uses a polarizing filter to distinguish the left image and the right image. Or both blue and red sunglasses are seen in passive mode. The active method is a method of distinguishing left and right images by sequentially covering the left eye (left eye) and the right eye (right eye) in a temporal manner by using a liquid crystal shutter. That is, the active method is a method of periodically repeating a time-divided screen and writing glasses wearing electronic shutters synchronized with the period, and may be a time split type or a shuttered glass type . Representative examples of the non-eyewear method that does not wear glasses include a lenticular method in which a lenticular lens plate in which a cylindrical lens array is arranged vertically is installed in front of the image panel, And a barrier layer having a barrier layer (not shown).

Hereinafter, the stereoscopic method will be described as an example of the 3D display method, and the stereoscopic method will be described as an active method. Hereinafter, the shutter glasses will be described as an example of the active medium, but the present invention is not limited thereto.

The output formatter 119 outputs the configured three-dimensional image data to the display unit 120 and synchronizes the outputted three-dimensional image data with the shutter glasses 121, Signal Vsync is generated and output to an IR emitter (not shown) in the shutter glasses to be viewed by the shutter glasses 121 in accordance with the display synchronization.

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

2 is a view showing a configuration of a 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 function to simply pass or block 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 light, the right eye shutter liquid crystal panel 230 blocks the light transmission, and the left image is transmitted only to the left eye of the eyeglass user . 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 light transmission, the right eye shutter liquid crystal panel 230 passes light, .

In this process, the infrared ray receiver 160 of the shutter glasses 150 converts the infrared ray signal received from the digital broadcast receiver into an electric signal and supplies the electric signal to the controller 170. The controller 170 controls the left and right shutter liquid crystal panel 200 and the right eye shutter liquid crystal panel 230 to be turned on and off alternately in accordance with 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 to the digital broadcast receiver by the infrared transmission / reception unit 160.

Meanwhile, the three-dimensional image data may be implemented in 3D by various methods such as giving a tilt or depth, or giving a 3D effect. Hereinafter, Will be briefly described.

The digital broadcast receiver processes the three-dimensional image data using the principle of the stereoscopic method. That is, when one object is photographed with two cameras at different positions to generate left image data and right image data, and the generated image data is separately input to the left eye and right eye of a person so as to be orthogonal to each other, In the brain, image data input to the left eye and the right eye are combined to generate a three-dimensional image. In the above description, the image data are arranged to be orthogonal to each other, meaning that the respective image data do not interfere with each other.

3 is a view for explaining a perspective view according to the interval or time difference (hereinafter referred to as interval) between the left image data and the right image data.

3 (a) illustrates a position 303 of an image formed by overlapping the positive data when the distance between the right image data 301 and the left image data 302 is narrow, and FIG. 3 (b) 311 and the left image data 312 are wide is described.

3 (a) to 3 (b) show the degree of perspective feeling that 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 shows extension lines R1 and R2 that look at one side and the other side of the right image data 301 in the right eye, and the left side looks at one side and the other side of the left image data 302 The extension line R1 for the right image data and the extension line L1 for the left image data are arranged at a point 303 where they cross each other at a predetermined distance d1 from the right eye and the left eye when drawing the extension lines L1 and L2, It is concluded.

3 (b), when the extension line R3 for the right image data and the extension line L3 for the left image data are separated from the right eye and the left eye by a predetermined distance d2 at the point 313 intersecting with each other.

Here, when d1 in Fig. 3 (a) and d2 in Fig. 3 (b) showing distances from the left eye and the right eye to the images 303 and 313 are compared, it is found that d1 is more distant from the left eye or right eye than d2 far. That is, the image in Fig. 3 (a) is formed at a farther distance from the left eye and the right eye than the image in Fig. 3 (b).

This is due to the interval between the right image data and the left image data (east-west direction based on the drawing).

For example, the interval between the right image data 301 and the left image data 302 in FIG. 3 (a) is the same as the interval between the right image data 303 and the left image data 304 in FIG. 3 (b) As shown in Fig.

3 (a) and 3 (b), the image formed by the combination of the left image data and the right image data becomes distant from the human eyes and distant as the interval of each image data becomes narrower.

FIG. 4 is a diagram illustrating an example of a method for implementing a 3D UI in connection with the present invention.

4A and 4B illustrate a UI including a plurality of items as a three-dimensional image. In FIG. 4A, the left image data 401 and the right image data 401 The interval between the left image data 404 and the right image data 405 constituting the UI is wide in the case of FIG. 4 (b).

Accordingly, the 3D UIs 403 and 406 implemented according to the intervals of the image data in FIGS. 4 (a) and 4 (b) are based on the principle of FIG. 3, The 3D UI 406 embodied in FIG. 4 (b) is formed close to the human eye and appears closer, that is, relatively more protruding, than the human eye. By adjusting the above-described principle, that is, the interval between the left image data and the right image data that constitute the UI, an appropriate degree of depth can be given to the corresponding UI.
