1 is a view showing an entire system including a display device according to an embodiment of the present invention. Hereinafter, referring to FIG. 1, an entire system including a display device according to an embodiment of the present invention will be described.

As shown in FIG. 1, the display apparatus 100 according to an exemplary embodiment of the present invention includes a tuner 110, a demodulator 120, a network interface 130, an external device interface 140, and a memory 150. , A controller 160, a user interface 170, a display module 180, and a speaker 190. However, the modules shown in FIG. 1 are one embodiment, and it is possible to add or delete some modules as required by those skilled in the art. Therefore, the scope of the present invention should be determined in principle by the claims.

The tuner 110 selects, for example, an RF broadcast signal corresponding to a channel selected by a user or all pre-stored channels among RF (Radio Frequency) broadcast signals received through an antenna. The demodulator 120 receives the digital IF signal DIF converted by the tuner 110 and performs a demodulation operation.

The demodulator 120 outputs a TS (Transport Stream) signal after performing channel decoding. In this case, the TS signal may be a signal multiplexed with a video signal, an audio signal, or a data signal. For example, the stream signal may be an MPEG-2 Transport Stream (TS) multiplexed with an MPEG-2 standard video signal, a Dolby AC-3 standard audio signal, and the like.

The TS signal output from the demodulator 120 is input to the controller 160. The controller 160 performs demultiplexing, image / audio signal processing, and the like, and then outputs video data to the display module 180 and outputs audio data to the speaker 190.

The external device interface 140 connects to an external device such as a DVD (Digital Versatile Disk) player, a BD (Blu-ray Disc) player, a game device, a camera, a camcorder, a computer (laptop), or the like by wire or wirelessly. . Furthermore, an application or a list of applications in a neighboring external device is received and transferred to the controller 160 or the memory 150.

The network interface 130 may include, for example, an Ethernet terminal for connection with a wired network, and for example, for connection with a wireless network, for example, a wireless LAN (WLAN). Fi, Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) communication standards, and the like can be used. In addition, the network interface 130 selects and receives a desired application from among applications that are open to the public through a network.

The memory 150 may store a program for processing and controlling each signal in the controller 160, and stores a processed video, audio, or data signal. In addition, the memory 150 stores channel information or an application received from the tuner 110, the network interface 130, and the external device interface 140.

The user interface 170 may receive a control signal from an external remote controller 195 or design a local key button attached to the display apparatus 100. The remote controller 195 will be described in detail with reference to FIGS. 8 and 9.

The controller 160 demultiplexes the data received through the tuner 110, the demodulator 120, the network interface 130, and the external device interface 140, or processes the demultiplexed signals. Generates and outputs a signal for video or audio output. The controller 160 will be described in more detail with reference to FIG. 2.

The display module 180 converts an image signal, a data signal, an OSD signal, etc. processed by the controller 160 into R, G, and B signals, respectively, to generate a driving signal. The display module 180 may be implemented as, for example, a PDP, an LCD, an OLED, a flexible display, a 3D display, or the like.

The speaker 190 corresponds to a module that receives and outputs an audio signal processed by the controller 160, for example, a stereo signal, a 3.1 channel signal, or a 5.1 channel signal.

FIG. 2 is a block diagram illustrating the controller shown in FIG. 1 in more detail. Hereinafter, the controller in the display device according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

As shown in FIG. 2, the controller in the display device according to an exemplary embodiment of the present invention may include a demultiplexer 161, an image processor 163, an OSD generator 162, a mixer 167, and a frame rate converter 168. , Formatter 169, and audio processor 166. However, the controller shown in Figure 2 is one embodiment for the description of the present invention, in principle, the scope of the present invention should be defined by the claims.

The demultiplexer 161 demultiplexes input data (for example, TS), and the image processor 163 performs image processing of the demultiplexed image signal. Therefore, the image processor 163 further includes a decoder 164 and a scaler 165.

The decoder 164 decodes the demultiplexed video signal, and the scaler 165 performs scaling so that the resolution of the decoded video signal can be output from the display module. The audio processor 166 processes the demultiplexed audio data in a form that can be output through a speaker.

The OSD generator 162 generates an OSD signal in accordance with a user input or itself. For example, based on a control signal from a user interface or automatically, a signal for displaying various types of information on a screen of a display module in graphic or text is generated.

The mixer 167 mixes the OSD signal generated by the OSD generator 162 and the image signal decoded by the image processor 163. Thus, broadcast data and various OSD graphics are displayed in an overlaid type at the same time.

The frame rate converter (FRC) 168 may convert a frame rate of an input image. For example, a 60Hz frame rate is converted to 120Hz or 240Hz. When converting a frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame or insert a third frame predicted from the first frame and the second frame between the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or three predicted frames. Meanwhile, it is also possible to maintain the input frame rate without additional conversion.

The formatter 169 receives an output signal of the frame rate converter 168 and changes the format to a format that can be output from the display module. For example, the R, G, and B data signals may be output, and the R, G, and B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS.

1 and 2, a process in which a display apparatus according to an embodiment of the present invention performs a reward function on a plurality of contents will be described in detail as follows.

The tuner 110 receives a broadcast program from a broadcast station. The broadcast program includes, for example, audio data and video data. Further, the demultiplexer 120 demultiplexes the received audio data and video data.

The memory 150 stores data listing at least one or more content with a record that has been previously executed. The content, for example, corresponds to a channel or other item. The memory 150 will be described later in more detail with reference to FIGS. 3 to 6.

The user interface 170 receives a command related to data stored in the memory 150. The command is, for example, a signal for requesting listing information about contents of a specific group among data stored in the memory 150.

The OSD generator 162 in the controller 160 generates graphic data listing the at least one content by using the data stored in the memory 150. Of course, it is also within the scope of the present invention that the OSD generator 162 is designed as a separate module from the controller 160.

The mixer 167 in the controller 160 mixes video data of the broadcast program and graphic data generated by the OSD generator 162. Of course, it is also within the scope of the present invention that the mixer 167 is designed as a separate module from the controller 160.

In addition, the controller 160 controls the mixed video data and the graphic data to be output through the display module 180. This will be described later in detail with reference to FIG. 7.

Furthermore, according to another embodiment of the present invention, it is assumed that the user interface 170 receives a command for selecting an area in which the channel list and the item list are not displayed. At this time, the controller 160 stops the output of the graphic data to be listed, and controls to output the video data in full screen. It will be described later in detail with reference to Figure 14a and 14b.

In addition, according to another embodiment of the present invention, the controller 160 controls to display an indicator for the guide when the number of items or channels included in the graphic data is greater than or equal to a preset limit value. When an indicator is selected through the user interface 170, the controller controls to display a list including an item or a channel that is not currently displayed on the screen. It will be described later in detail with reference to Figure 15a and 15b.

3 is a diagram illustrating an example of a data format for providing a receive function for a plurality of groups according to an embodiment of the present invention. Hereinafter, referring to FIG. 3, an example of a data format for providing a reward function for a plurality of groups according to an embodiment of the present invention will be described.

According to one embodiment of the invention, the "recent" function is newly defined. The Recent function is a function of quickly listing channels and items having a recently used history among respective contents belonging to, for example, a first group (channel) and a second group (remaining items). Thus, in order to perform the aforementioned reward function, for example, two factors are required.

First, an extraction criterion for determining a channel or item with a recently used history is needed. In addition, when it is determined that the channel or item having a recently used history, a criterion for what information is displayed in the list is required.

As shown in FIG. 3, when the display device according to an embodiment of the present invention is tuned in a certain first channel for a specific time or longer (for example, 10 seconds or more), a recently accessed history is displayed. It is assumed to be present. Thus, the first channel is stored in a first list related to the accent function.

In addition, when an arbitrary channel is included in the first list, a thumbnail image, a channel number, or a channel name of the arbitrary channel is mapped together and stored in the first list. Meanwhile, a solution for obtaining a thumbnail image of a channel included in the first list will be described later with reference to FIG. 4.

On the other hand, as shown in Figure 3, the extraction criteria of the remaining items other than the channel, mainly determines whether there is a history of each item executed. Store recently executed items in a second list associated with the Recent function. The items include, for example, at least one or more of a video, a photo, a music, an application, a web, a setting, and an input device.

Furthermore, as shown in FIG. 3, according to an embodiment of the present invention, a list of channels with recently tuned history and a list of items with recently used history are separately managed. This will be described later in more detail with reference to FIGS. 5 and 6.

4 is a diagram illustrating another example of a data format for providing a receive function for a plurality of groups according to an embodiment of the present invention. Hereinafter, another example of a data format for providing a residual function for a plurality of groups according to an embodiment of the present invention will be described with reference to FIG. 4.

As described above, information about channels tuned for a predetermined time or more is stored in a list. At this time, the thumbnail image data for each channel is designed to be stored together in the list.

As shown in FIG. 4, corresponding thumbnail images may be extracted according to four priorities. In addition, the data format shown in FIG. 4 is stored in a memory, and the priority shown in FIG. 4 is an embodiment. Therefore, the scope of the present invention is not limited only by the priorities shown in FIG. 4.

According to an embodiment of the present invention, when a particular channel is tuned for more than the predetermined time, thumbnail image data is generated by capturing a currently displayed screen. In addition, according to another embodiment of the present invention, the representative thumbnail image data for the particular broadcast program currently displayed is received from the CP (Content Provider) and stored.

Furthermore, according to another embodiment of the present invention, when a particular channel is tuned for the predetermined time or more, graphic data corresponding to a channel logo or channel number is designed to be stored in a list.

5 and 6 illustrate another example of a data format for providing a rest function for a plurality of groups according to an embodiment of the present invention. Hereinafter, another example of a data format for providing a reward function for a plurality of groups according to an embodiment of the present invention will be described with reference to FIGS. 5 and 6.

For example, a recently accessed channel list and a recently accessed item list may be generated based on the data shown in FIGS. 3 to 4. In particular, as shown in FIG. 5, the channel list is designed to be stored in the first address of the memory, and the item list is designed to be stored in the second address of the memory. Therefore, when designing a memory address as shown in FIG. 5, the user has an advantage in that he / she can check a list of channels recently accessed and a list of other items, respectively.

As shown in FIG. 5, it is assumed that there is a recently tuned history in the order of channel 7, channel 5, channel 4, channel 11,... Channel 9 in the case of the channel list. On the other hand, in the case of other item lists (except channels), it is assumed that there is a history that is recently tuned in the order of ace book, website, photo (file name: KIM), bed reservation, .... photo (file name: YS). It was.

Furthermore, assuming that a user watches channel 8 broadcast based on the current time point and uses a movie titled Movie, the list of memory addresses shown in FIG. 5 is changed to the list of memory addresses shown in FIG. .

That is, as shown in FIG. 6, channel 8 occupies the highest rank in the channel list of the memory first address. In the item list of the second address of the memory, the video titled the movie occupies the highest rank.

FIG. 7 is a diagram illustrating graphic data on which a reward function for a plurality of groups is executed according to an embodiment of the present invention. Hereinafter, referring to FIG. 7, graphic data on which a reward function is executed for a plurality of groups according to an embodiment of the present invention will be described.

When the accent function described above with reference to FIGS. 1 to 6 is executed, as illustrated in FIG. 7, the display apparatus 700 according to an exemplary embodiment displays different video data in two areas.

Video data of general broadcast data is output to the first region 710. On the other hand, the channel list 730 and the item list 740 stored in each of the addresses of the memory are output to the second area 720.

In the channel list 730, the corresponding thumbnail image data are displayed in the order of SBC, KBC1, KBC2, and MBS. The order is the order of the channels accessed sequentially from the most recently accessed channel by the user.

In the item list 740, a corresponding icon or graphic is displayed in the order of an ace book, a website (BAUM), a photo (file name: KIM), and a T application. The order is the order of items accessed in order from the most recently accessed item by the user.

In addition, the deletion mode 750 illustrated in FIG. 7 is an option for quickly deleting contents not desired by the user of the display apparatus 700 from the aforementioned channel list 730 and item list 740. This will be described later in detail with reference to FIG. 13.

In addition, various options illustrated in FIG. 7 may be selected using the remote controller 795 according to an embodiment of the present invention. Feedback graphic data 796 corresponding to the input signal of the remote controller 795 is displayed on the screen. For example, when the feedback graphic data 796 is located at the exit option 760 according to the movement of the remote controller 795, the display returns to the previous screen. For example, all of the lists displayed in the second area 720 disappear.

Therefore, as shown in FIG. 7, when the broadcast data and the graphic data listing the channel and the item are designed to be displayed at the same time, the user can easily check the broadcast currently being received and at the same time, facilitate the previous usage history of the plurality of content groups. There is an advantage that can be confirmed.

Meanwhile, the remote controller 795 illustrated in FIG. 7 will be described later in more detail with reference to FIGS. 8 and 9.

FIG. 10 is a diagram illustrating a first process for executing a reward function for a plurality of groups according to an embodiment of the present invention. Hereinafter, referring to FIG. 10, a first process for executing a reward function for a plurality of groups according to an embodiment of the present invention will be described. In particular, FIG. 10 illustrates a process of selecting a specific channel that the user has recently accessed.

First, as shown in FIG. 7, it is assumed that a broadcast screen is output in a first area and a recently used content list of two groups is output in a second area. The second area is included in the first area, for example, and the portion where the first area and the second area overlap, treats the broadcast screen as an opaque graphic. In addition, the two groups correspond to, for example, a group for a channel and a group for an item.

As shown in FIG. 10A, a specific SBC channel 1097 is selected from a recently tuned channel list using the remote controller 1095 according to an embodiment of the present invention. For example, when the indicator 1096 whose position changes according to the movement of the remote controller 1095 stays in the specific SBC channel 1097 for a predetermined time or more, it is assumed that the specific SBC channel is selected. Or, if another indicator button (for example, a confirmation button) is pressed after the indicator 1096 is located on the particular SBC channel 1097, it is assumed that the particular SBC channel is selected.

Therefore, as shown in (b) of FIG. 10, instead of the channel that was tuned in (a) of FIG. 10, the tuning is performed to the SBC channel. Furthermore, it is also within the scope of the present invention to enhance the convenience of the user by simultaneously disappearing the channel and the item list.

FIG. 11 is a diagram illustrating a second process of executing a reward function for a plurality of groups according to an embodiment of the present invention. Hereinafter, referring to FIG. 11, a second process for executing a reward function for a plurality of groups according to an embodiment of the present invention will be described. In particular, FIG. 11 illustrates a process of selecting a specific item that a user has recently accessed.

First, as shown in FIG. 7, it is assumed that a broadcast screen is output in a first area and a recently used content list of two groups is output in a second area. The second area is included in the first area, for example, and the portion where the first area and the second area overlap, treats the broadcast screen as an opaque graphic. In addition, the two groups correspond to, for example, a group for a channel and a group for an item.

As shown in FIG. 11A, a specific application 1197 is selected from a list of items that have been recently executed using the remote controller 1195 according to an embodiment of the present invention. For example, if the indicator 1196 whose position changes with the movement of the remote controller 1195 stays in the specific application 1197 for a predetermined time or more, it is assumed that the specific application is selected. Or, if another indicator button (for example, a confirmation button) is pressed after the indicator 1196 is located in the specific application 1197, it is assumed that the specific application is selected.

Therefore, as shown in (b) of FIG. 11, instead of the channel tuned in (a) of FIG. 11, the above-described specific application is designed to be executed. Also, FIG. 10 illustrates an embodiment in which a broadcast mode is maintained, whereas FIG. 11 illustrates an embodiment in which a broadcast mode is changed from an application execution mode.

12 is a diagram illustrating a third process of executing a reward function for a plurality of groups according to an embodiment of the present invention. Hereinafter, referring to FIG. 12, a third process for executing a reward function for a plurality of groups according to an embodiment of the present invention will be described.

In FIG. 10 and FIG. 11, the user is limited to selecting only one desired content in the channel and item list. 12, a solution for selecting all of a specific channel and a specific item from the channel and the item list will be described.

First, the confirmation button of the remote controller 1295 in a state in which the indicator 1296 whose position changes according to the movement of the remote controller 1295 shown in FIG. 12A is located on a specific broadcast channel 1297. If is pressed twice, it is tuned directly to the specific broadcast channel 1297.

However, when the indicator 1296 is positioned on a specific broadcast channel 1297, the controller 1295 is designed not to tune directly to the specific broadcast channel 1297 when the confirmation button of the remote controller 1295 is pressed only once. In addition, when designing together, there is an advantage in that a specific item can be additionally selected from an item list instead of a channel.

Therefore, when the confirmation button of the remote controller 1295 is pressed twice while the indicator 1296 is located in the specific application 1298 while the specific broadcast channel 1297 is highlighted, FIG. Is switched to the double mode shown in

As shown in FIG. 12B, a broadcast program from the selected specific channel 1297 is displayed in the left region of the screen, and the selected specific application 1298 is executed in the right region of the screen. Of course, adjusting the position and shape of each region is within the scope of the present invention.

13A to 13D are diagrams illustrating a fourth process of executing a reward function for a plurality of groups according to an embodiment of the present invention. Hereinafter, referring to FIGS. 13A to 13D, a fourth process of executing a reward function for a plurality of groups according to an embodiment of the present invention will be described.

1 to 12 have described the process of simultaneously displaying a list for a channel group and an item group stored in a memory when the accent function according to an embodiment of the present invention is executed. However, in some cases, when there is content that the user does not want in each list, a solution for quickly deleting the content is needed, which will be described with reference to FIG. 13.

When the accent function according to an embodiment of the present invention is executed, a list of recently tuned channels and a list of recently executed items are displayed as shown in FIG. 13A. It may be supplementally interpreted with reference to FIG. 7.

In this case, as shown in FIG. 13A, when the indicator 1396 of the remote controller 1395 is located in an area 1397 in which the delete mode can be selected, as shown in FIG. 13B, all the contents included in the list are displayed. The graphic data is changed. In addition, when comparing FIGS. 13A and 13B, the delete mode area 1397 is changed to the delete button 1350.

For example, as illustrated in FIG. 13B, a check box 1301 for selecting content to be deleted is displayed. In this case, it is assumed that the indicator 1396 of the remote controller 1395 is positioned in the specific channel 1380. Of course, although only one channel is selected in FIG. 13B, it is also possible to simultaneously delete a plurality of channels and a plurality of items from the list.

As shown in FIG. 13C, a V-shaped graphic has been added to the check box 1301 of the particular channel 1380. This serves to inform the selection, and can be designed in different shapes and colors. In addition, as shown in FIG. 13C, when the indicator 1396 of the remote controller 1395 is placed on the delete button 1350, and then the confirmation button is pressed, the indicator 1313 is converted to the graphic data of FIG. 13D.

That is, as shown in FIG. 13D, a message 1310 indicating that the selected specific channel has been deleted from the percentage list is displayed. Furthermore, the display device according to an embodiment of the present invention is designed to delete the specific channel from the list stored in the memory and move the positions of the remaining channels forward in the channel list as shown in FIG. 13D.

Also, as shown in FIG. 13D, the delete button is changed back to an area 1397 in which the delete mode can be selected. Therefore, the user has an advantage of more quickly selecting a channel to be deleted again.

13 will be described as follows. According to an exemplary embodiment of the present invention, a display apparatus includes a first list (channel list shown in FIG. 13A), a second list (other list shown in FIG. 13A), and an indicator for the delete mode (1397 in FIG. 13A). ) Is displayed.

When the indicator (1397 shown in FIG. 13A) is selected, first graphic data indicating an item or channel listed in each of the lists is converted into second graphic data. That is, when comparing FIGS. 13A and 13B, the first graphic data corresponds to thumbnail image data that does not include a check box (FIG. 13A). In contrast, the second graphic data corresponds to thumbnail image data including a check box (FIG. 13B).

In addition, referring to the second graphic data (1301 and 1380 of FIG. 13B), when a specific item or a specific channel is selected, the selected specific item or a specific channel is deleted from the memory and the display on the corresponding list is stopped. (See d in FIG. 13).

14A and 14B are diagrams illustrating a fifth process of executing a reward function for a plurality of groups according to an embodiment of the present invention. Hereinafter, referring to FIGS. 14A and 14B, a fifth process of executing a reward function for a plurality of groups according to an embodiment of the present invention will be described.

When the accent function according to an embodiment of the present invention is executed, the graphic data shown in Fig. 14A is output. In this case, the display screen illustrated in FIG. 14A may be divided into four areas.

The first area 1410 and the fourth area 1440 are areas in which video data of a broadcast program is output but does not include graphic data related to a reward function. On the other hand, the second area 1420 and the third area 1430 are areas including both video data of a broadcast program and graphic data displaying a list related to a reward function. However, in the second area 1420 and the third area 1430, the graphic data is displayed in a type overlaid on the video data of the broadcast program.

At this time, when the indicator 1496 of the remote controller is located in the first region 1410 or the fourth region 1440 shown in FIG. 14A for a predetermined time or after the specific button (for example, an OK button) is selected. If so, it is switched to FIG. 14B.

That is, as shown in FIG. 14B, the display apparatus 1400 according to an embodiment of the present invention stops displaying the list in the previous second area 1420 and the third area 1430, and broadcasts the program. Only video data is designed to be output in the whole area.

As shown in FIG. 15A, a list of recently tuned channels is displayed in a first region 1510, and a list of recently executed items is displayed in a second region 1520. However, the regions 1510 and 1520 described above all occupy limited space. Therefore, it is difficult to display all the contents of the list stored in the memory at the same time.

In order to overcome this limitation, when all the contents of the list stored in the memory cannot be displayed simultaneously on one screen (for example, when the number of channels or items recorded in the list exceeds five), FIG. 15A As shown in FIG. 2, graphic data 1500 that may move to another page is output.

At this time, the indicator 1596 of the remote controller 1595 can be positioned in the graphic data 1500 to turn pages in the left or right direction. For example, when the indicator 1596 selects the right arrow of the graphic data 1500, the indicator 1596 switches to the screen shown in FIG. 15B.

In FIG. 15A, channel 1, channel 2, channel 3, channel 4, and channel 5 are listed in a first region 1510, and item 1, item 2, item 3, item 4, and item 5 are listed in a second region 1520. Although FIG. 15B lists channel 6, channel 7, channel 8, channel 9, and channel 10 in the first region 1530, item 6, item 7, item 8, and item 9 are listed in the second region 1540. , Listing item 10. Therefore, in the case of designing as shown in FIGS. 15A and 15B, there is an advantage in that the contents listed in the list can be checked in group units or page units.
