Accordingly, the controller 170, particularly, the image processing unit 320 and the like can process the 2D video signal, the mixed video signal of the 2D video signal and the 3D video signal, , A 3D video signal can be output.

Meanwhile, the image signal decoded by the image processing unit 320 may be a 3D image signal in various formats. For example, a 3D image signal composed of a color image and a depth image, or a 3D image signal composed of a plurality of view image signals. The plurality of viewpoint image signals may include, for example, a left eye image signal and a right eye image signal.

Here, the format of the 3D video signal is a side-by-side format in which the left-eye image signal L and the right-eye image signal R are arranged in left and right directions, a top- An interlaced format in which the left and right eye image signals and the right eye image signal are mixed line by line, a checker box for mixing the left eye image signal and the right eye image signal box by box, Format, and the like.

On the other hand, the formatter 360 can change the format of the 3D video signal. For example, it can be changed to any one of the various formats described above.

Meanwhile, the formatter 360 may convert the 2D video signal into a 3D video signal. For example, according to a 3D image generation algorithm, an edge or a selectable object is detected in a 2D image signal, and an object or a selectable object according to the detected edge is separated into a 3D image signal and is generated . At this time, the generated 3D image signal can be separated into the left eye image signal L and the right eye image signal R, as described above.

The 3D processor (not shown) can process the brightness, tint, and color of the image signal to improve the 3D effect. For example, it is possible to perform signal processing such as making the near field clear and the far field blurring. On the other hand, the functions of such a 3D processor can be merged into the formatter 360 or merged into the image processing unit 320. [

Meanwhile, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the audio processing unit (not shown) may include various decoders.

8 is a flowchart illustrating a method of operating an image display device according to an exemplary embodiment of the present invention, and FIGS. 9 to 13B are views referred to for describing various examples of the method of FIG. 8.

First, the video display device 100, in particular, the controller 170 determines whether the recording mode is set (S810). The recording mode setting may be set by user input.

For example, when a user performs an input for displaying a reservation recording menu for scheduled recording, the controller 170 of the video display device 100 may control the reservation recording menu to be displayed on the display 180. have.

FIG. 11A illustrates that a user selects a desired program item 1110 while the EPG screen 1100 is displayed on the display 180. As a result, the user can easily perform a recording mode setting for a desired broadcast program.

In the drawing, a remote control apparatus 200 capable of displaying a pointer is illustrated, but a corresponding program item may be selected by using a direction key of a general remote controller or a direction key of a local key.

In particular, when the recording mode is set in advance, the image display device 100 determines whether or not the recording start time is reached in operation S815. In operation S820, the broadcast signal according to the recording mode is received.

As shown in FIG. 11A, when the start time of the recording scheduled program is 8:00 PM (Pm 8:00), the controller 170 determines whether the corresponding time is reached, and, if applicable, the broadcast signal according to the recording mode. Control to receive.

For example, when the user is watching the channel 6-1 through the video display device and the recording time point is reached, the video display device 100 broadcasts the broadcast signal of the channel 7-1, which is set in advance in the recording mode. The broadcast receiving unit 105 may be controlled to receive.

When the video display device 100 includes a plurality of tuners, the broadcast signal of the channel 6-1, which is viewed in advance, is received through the first tuner, and from the time of recording, the broadcast signal of the channel 7-1 is separately added. It is possible to receive via a second tuner. Therefore, the video representation apparatus 100 can continuously display the broadcast video corresponding to the broadcast signal of the channel 6-1, regardless of the recording mode.

Meanwhile, as another example, when one tuner is provided instead of a plurality of tuners, the tuner may change the broadcast signal of channel 6-1 into the broadcast signal of channel 7-1 and receive the tuner. Accordingly, the display 180 of the image display apparatus 100 may display the broadcast image of the channel 6-1 and display the broadcast image of the channel 7-1 from the start of recording.

Meanwhile, when the image display apparatus 100 is turned off before the recording time, the image display apparatus 100 may be turned on to perform the recording mode at the time of the recording, and the broadcast signal of the corresponding channel may be received. .

Next, the video display device 100 checks in particular whether the image indicating the broadcast information included in the broadcast signal is present (S825). If there is an image representing broadcast information (S830), the broadcast content corresponding to the broadcast signal is stored according to the set recording mode (S835). On the other hand, when there is no image representing the broadcast information (S830), the broadcast content corresponding to the broadcast signal is stored according to the set recording mode (S840).

As illustrated in FIG. 11A, when a recording mode is set by using electronic program guide (EPG) information included in a broadcast signal, an advertisement between the program and the program may be recorded.

As shown in FIG. 11A, the start time of the program item (Oh! Lady) 1110 to be recorded is illustrated as pm 8:00, but the end time of the previous broadcast program item (BRING IT ON) is also pm 8:00. Illustrated as being. However, the start time of the program item (Oh! Lady) 1110 to be recorded may be pm 8:05, pm 8:10, etc., not pm 8:00. This may vary depending on broadcaster circumstances.

According to an embodiment of the present invention, when recording a broadcast program, a method of recording only a desired program without advertisements is proposed.

To this end, the controller 170 checks whether an image representing broadcast information included in the broadcast signal exists.

On the other hand, as an image existence confirmation method indicating the broadcast information included in the broadcast signal, it will be described with reference to Figs.

First, referring to FIG. 9, the controller 170 extracts a broadcast video image of a received channel corresponding to a recording mode in order to determine whether an image representing broadcast information included in a broadcast signal exists (see FIG. 9). S910).

The controller 170 extracts a broadcast video image corresponding to a broadcast program to be recorded. For example, the image processor 320 of FIG. 3 may extract an image in units of frames from the decoded broadcast image.

In addition, the controller 170 compares the extracted broadcast video image with a previously stored broadcast information image or a broadcast information image received through a network (S920). In operation S930, it is determined whether an area corresponding to the broadcast information image exists in the extracted broadcast video image.

According to an embodiment of the present invention, the advertisement video and the advertisement image may be included in the extracted broadcast video image through whether or not there is an image including a channel name (MBS, CBB, KBB, NCC, etc.) representing the broadcast channel or a logo corresponding thereto. Separate program images.

To this end, the controller 170 compares the broadcast information image pre-stored in the storage 140 or the broadcast information image received through the network interface 135 with the extracted broadcast image.

The broadcast information image previously stored in the storage 140 may be classified and stored for each broadcast channel. The broadcast information image may be received from a predetermined server through the network interface unit 135 and stored.

Meanwhile, in order to receive a broadcast information image from a server in real time through a network, the video display device 100 may transmit channel information, recording time information, and the like in the recording mode to the server 500.

The controller 170 determines whether the broadcast information image previously stored in the storage 140 or the broadcast information image received through the network interface unit 135 and the extracted broadcast image have the same area, and is extracted. It is determined whether a region corresponding to the broadcast information image exists in the broadcast video image.

Next, referring to FIG. 10, the controller 170 extracts a broadcast video image of a received channel corresponding to a recording mode to determine whether an image representing broadcast information included in a broadcast signal exists (see FIG. 10). S1010). This corresponds to step 910 of FIG. 9.

The controller 170 transmits the extracted broadcast video image to the server (S1020). In operation S1030, information indicating whether an area corresponding to the broadcast information image is present among the broadcast video images extracted from the server is received.

That is, unlike FIG. 9, the video display device 100 determines whether there is an image including a channel name (MBS, CBB, KBB, NCC, etc.) or a logo corresponding to each broadcast channel in the extracted broadcast video image. The server 500 may make a judgment instead of making a judgment. Accordingly, the server 500 transmits the information to the video display device 100, and the video display device 100, particularly the control unit 170, broadcasts the broadcast information included in the broadcast signal through the received information. Checks whether the representing image exists

Next, the video display device 100, in particular, the controller 170 determines whether or not it is the end point of recording (S845). When the recording ends, the storage of the broadcast content is stopped, and when not, the steps S825 to S840 are repeatedly performed to continue recording.

Referring to FIG. 11B, in the case of the first time (T = t1) after the start of the recording time point, for example, at 8:00 pm, the video display device 100 records through the set top box 250. The broadcast signal 1105 of the channel 7-1 set to the mode may be received. In this case, the display 180 illustrates that the advertisement image 1120 is displayed instead of the broadcast program (Oh! Lady) to be recorded.

The controller 170 of the image display apparatus 100 extracts an image of the advertisement image 1120 and compares it with a previously stored broadcast information image or a broadcast information image received through a network, and determines whether the broadcast program image or the advertisement image. Check it.

In Fig. 11B, although the channel number is shown, the channel names (MBS, CBB, KBB, NCC, etc.) indicating the broadcast channels are not displayed, and the broadcast program names (Oh! Lady, ABC news, DR. OZ, etc.) are also displayed. It is not displayed. Accordingly, the controller 170 determines that the image 1120 of FIG. 11B is an advertisement image by detecting a logo such as a channel name, and although the recording time, the image 1120 is stored in the storage 140. ) Is not saved.

Referring to FIG. 11C, when the second time is T = t2, for example, when pm is 8:05, the video display device 100 is set to the recording mode through the set top box 250. The broadcast signal 1105 of -1 is continuously received. In this case, the display 180 shows an example of displaying a broadcast program image (Oh! Lady) 1130 to be recorded instead of an advertisement image.

The control unit 170 of the image display apparatus 100 extracts an image of the broadcast program image 1130 to be recorded, compares it with a previously stored broadcast information image or a broadcast information image received through a network, and determines whether the broadcast program image is the corresponding broadcast program image. Check if the video is advertising.

11C exemplarily shows that a channel number, a channel name (MBS HD) 1145 representing a broadcast channel, and a broadcast program name (Oh! Lady) are displayed. Accordingly, the controller 170 determines that the image 1130 of FIG. 11C is a broadcast program image to be recorded by detecting the image region 1140 including the channel name 1145 and the like. In addition, the image 1130 is stored in the storage 140.

Next, FIG. 11D illustrates an image area 1140 including a channel name 1145 and the like in the received broadcast video 1150 at the third time (T = t3), for example, at 8:10 pm. Illustrates the existence of this. Accordingly, the video display device 100 continuously stores the video 1150 in the storage 140. In this case, for user convenience, the object 1155 indicating that the data is being stored may be displayed.

Next, FIG. 11E illustrates that the channel name 1145 or the like is not displayed in the received broadcast video 1160 when the fourth time (T = t4) is performed, for example, when PM is 8:30. For example, when an advertisement time is set in the middle of the program, as shown in FIG. 11E, the intermediate advertisement image 1160 may be displayed.

In this case, since the channel name MBS HD indicating the broadcast channel, the broadcast program name Oh! Lady, etc. are not displayed, the controller 170 determines that the image 1160 of FIG. 11E is an advertisement image. At the time of recording, the video 1160 is not stored in the storage 140.

Next, FIG. 11F illustrates an image area 1140 including a channel name 1145 and the like in the received broadcast video 1170 at the fifth time (T = t5), for example, at 8:35 pm. Illustrates the existence of this. Accordingly, the image display apparatus 100 continuously stores the image 1170 in the storage 140 again. In this case, for user convenience, the object 1155 indicating that the data is being stored may be displayed.

Next, in FIG. 11G, when the sixth time (T = t6), for example, at 9:00 pm, the channel name 1145 and the like are not displayed in the received broadcast video 1180 as the recording end time. Illustrates not.

In this case, the controller 170 determines that the image 1180 of FIG. 11G is an advertisement image because the channel name MBS HD indicating the broadcast channel, the broadcast program name Oh! Lady, and the like are not displayed. Although it is a recording time, the image 1180 is not stored in the storage 140.

As described above, when the recording mode is set, the image display apparatus checks whether an image representing broadcast information included in the broadcast signal exists and stores the broadcast content corresponding to the broadcast signal when the image exists. As a result, only broadcast content desired by a user can be accurately recorded. Accordingly, the usability of the user can be increased.

On the other hand, when the step (S825) of repeatedly checking whether or not the image indicating the broadcast information is present, the control unit 170, the confirmation period at the start of recording or the end of recording according to the recording mode is different, It can be set to be shorter than the confirmation period at the time.

That is, since the commercial video is normally received at the start of recording, by confirming the broadcast information image more frequently near the recording time, it is possible to accurately record only the desired program video.

In addition, since the advertisement video is normally received even at the end of the recording, by confirming the broadcasting information image more frequently near the recording time, it is possible to accurately record only the desired program video.

11A to 11G illustrate that the broadcast image is received through the set-top box 250, the broadcast image is different from the broadcast receiver 105 in the image display device 100, in particular, the tuner unit 110. It is also possible to receive directly through.

FIG. 12 illustrates comparing the extracted broadcast video image with a previously stored broadcast information image or a broadcast information image received through a network.

When the recording mode is performed, the controller 170 extracts the broadcast video image from the broadcast video 1130 of the set channel 7-1. The broadcast video image may be an entire frame, but illustrates a partial region 1140 in the drawing.

Since the partial region 1140 is continuously displayed at the same position in a plurality of frames, the controller 170 may extract such an region. The extracted image 1210 and the broadcast information image 1220 received from the server 500 connected through the network are compared. When the image 1210 and the broadcast information image 1220 of the extracted region are the same, the video display device 100 controls, in particular, the controller 170 to store broadcast content related to the broadcast program. Accordingly, the storage unit 104 stores all the video, audio, and the like of the broadcast program.

Next, FIG. 13A illustrates that real-time viewership information 1655 from the server 500 is transmitted to the video display device 100.

 The network interface unit 135 of the image display apparatus 100 may receive real-time viewership information 1655 from the server 500. Meanwhile, as illustrated in FIG. 12, the network interface unit 135 of the video display device 100 may receive the broadcast information image 1220 and the real-time viewership information 1655 together.

Meanwhile, the display 180 illustrates that the broadcast program image 1130 includes an image area 1140 including a channel name 1145 and the like. Accordingly, the storage 140 may store broadcast content related to the broadcast program.

Next, FIG. 13B illustrates that the video display device 100 displays the object 1355 and the broadcast video 1150 together showing real-time viewership information.

The controller 170 of the image display apparatus 100 generates an object 1355 representing the real-time viewership information by using the real-time viewership information 1355 from the server 500, and displays the object 1355. ) Can be displayed.

On the other hand, since the broadcast program image 1150 includes an image area 1140 including the channel name 1145 and the like, the storage unit 140 continues to store broadcast content related to the broadcast program. In this case, for user convenience, the object 1155 indicating that the data is being stored may be displayed.

14 is a flowchart illustrating a method of operating an image display device according to another exemplary embodiment of the present invention, and FIGS. 15A to 15C are diagrams for describing various examples of the method of FIG. 14.

The operation method of the image display apparatus of FIG. 14 is similar to the operation method of the image display apparatus of FIG. 8. The operation method of the image display apparatus of FIG. 8 is described based on the case where the recording mode is set in advance, and the operation method of the image display apparatus of FIG. 14 is described centering on the case where recording is performed immediately after setting the recording mode. .

Referring to FIG. 14, first, the video display device 100 receives a broadcast signal, in particular (S1405). In particular, the video display device 100 determines whether the recording mode is set in particular (S1410).

For example, as shown in FIG. 15A, the broadcast signal 1105 is received through the set top box 250, and the broadcast image 1120 of the channel 7-1 corresponding to the received broadcast signal is displayed on the display 180. When the specific key 295 of the remote control apparatus 200 is operated at the first time T = ta displayed at, it may directly enter the recording mode.

Accordingly, when the recording mode enters immediately, steps 1425 to 1445 (S1425 to S1445) are performed. Steps 1425 to 1445 (S1425 to S1445) correspond to steps 825 to 845 (S825 to S845) of FIG. 8.

That is, as shown in FIG. 15B, at the second time (T = tb), the video display device 100 continues to receive the broadcast signal 1105 of channel 7-1 set to the recording mode through the set top box 250. can do. In this case, the display 180 may display a broadcast program image (Oh! Lady) 1130, not an advertisement image.

The control unit 170 of the image display apparatus 100 extracts an image of the broadcast program image 1130 to be recorded, compares it with a previously stored broadcast information image or a broadcast information image received through a network, and determines whether the broadcast program image is the corresponding broadcast program image. Check if the video is advertising.

In particular, FIG. 15B illustrates that a channel number, a channel name (MBS HD) 1145 indicating a broadcast channel, and a broadcast program name (Oh! Lady) are displayed. Accordingly, the controller 170 determines that the image 1130 of FIG. 15B is a broadcast program image to be recorded by detecting the image region 1140 including the channel name 1145 and the like. In addition, the image 1130 is stored in the storage 140.

Next, FIG. 15C illustrates that an image region 1140 including a channel name 1145 and the like exist in the received broadcast image 1150 at a third time T = tc. Accordingly, the video display device 100 continuously stores the video 1150 in the storage 140. In this case, for user convenience, the object 1155 indicating that the data is being stored may be displayed.

Meanwhile, the recording may be terminated by input of a specific key or the like of the remote control apparatus 200. For example, when the specific key 295 of FIG. 15 is pressed once more, recording may end. In addition, if the recording is not to end, it may be repeated repeatedly, steps 1425 to 1445 (S1425 to S1445) may be performed.

On the other hand, when the step (S1425) of repeatedly checking whether or not an image representing broadcast information exists is repeatedly performed, the control unit 170 has different confirmation periods at the start of recording or the end of recording according to the recording mode. It can be set to be shorter than the confirmation period at the time.

Since the advertisement video is normally received at the start of recording or the end of recording, by confirming the broadcast information image more frequently near the time of recording or near the end of recording, only the desired program video can be recorded.

The image display device and the method of operating the same according to the present invention are not limited to the configuration and method of the embodiments described as described above, but the embodiments are all or all of the embodiments so that various modifications can be made. Some may be optionally combined.

Meanwhile, the operation method of the image display apparatus of the present invention can be implemented as a code that can be read by a processor on a recording medium readable by a processor included in the image display apparatus. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium that can be read by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet . In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.
