Description

Display device

Embodiments of the present invention relate to a display device.

In recent years, since television broadcasting has completely shifted from analog broadcasting to digital broadcasting, users can view television broadcasting with high definition. The resolution of digital broadcasting is 1440 × 1080i or 1920 × 1080i, but recently, a 4K resolution television apparatus capable of expressing a resolution of 1080i or higher has been released.

The 4K resolution television device can express a resolution four times that of a normal television device, that is, a resolution of 4096 × 2160i. For this reason, a 4K resolution television device has a space in which information other than the digital broadcast can be displayed while maintaining a high-definition resolution of 1920 × 1080i even when a normal digital broadcast is displayed. For example, it is possible to view the television broadcast while displaying a home game connected to the external input terminal of the television device in a space other than the area where the digital broadcast is displayed.

Recently, with the spread of smartphones and high-function mobile phones, an increasing number of users post comments in real time, for example, short comments while watching television broadcasts. Since this short post usually shows only the post of the person who followed it, the post to the program which the person who is not following is currently watching cannot see it. Therefore, although the posting of the program being viewed can be viewed by performing a posting search using the hash tag, there is a problem that the user cannot know the information of the hash tag.

It is an object of the embodiment of the present invention to provide a display device that can easily present the optimum hash tag information of a program being viewed to a user.

The display device of the embodiment includes a signal processing unit, a display unit, and a control unit. The signal processing unit separates the program information from the digital broadcast signal. The display unit displays a broadcast screen on which an image separated from a digital broadcast signal is displayed, a post comment screen on which a post comment of a hash tag related to a program displayed on the broadcast screen is displayed, and a post comment screen. A hash tag candidate screen on which a plurality of hash tag candidates to be displayed are displayed. The control unit extracts hash tag information from the program information separated from the digital broadcast signal, and displays the extracted hash tag information on the hash tag candidate screen.

It is a figure which shows the structure of the display apparatus which concerns on one embodiment. It is a figure for demonstrating the electrical structure of the display apparatus which concerns on one embodiment. It is a flowchart which shows the example of the flow of a hash tag search process. It is a flowchart which shows the other example of the flow of a hash tag search process. It is a figure for demonstrating the relationship between a display apparatus and the server which manages a hash tag.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, based on FIG.1 and FIG.2, the structure of the display apparatus which concerns on one Embodiment is demonstrated.

FIG. 1 is a diagram showing a configuration of a display device according to an embodiment, and FIG. 2 is a diagram for explaining an electrical configuration of the display device according to the embodiment.

As shown in FIG. 1, the display device 1 is a 4K television device having a resolution four times that of full high-definition and has a display unit 2 such as a 4K panel.

In the upper left side of the display unit 2, a broadcast screen 3 on which a digital broadcast video currently being viewed is displayed is arranged. This broadcast screen 3 displays a 1080i high-definition digital broadcast which is a full high-definition video.

On the right side of the display unit 2, a post comment screen 4 on which post comments of hashtags related to the program displayed on the broadcast screen 3 are displayed in real time is arranged.

In the lower left side of the display unit 2, a hash tag candidate screen 5 on which a plurality of hash tag candidates to be displayed on the posted comment screen 4 are displayed. The user can select a desired hash tag from a plurality of hash tag candidates displayed on the hash tag candidate screen 5.

Furthermore, between the broadcast screen 3 and the hash tag candidate screen 5, a posted comment writing screen 6 that can write a short posted comment is arranged.

Note that the arrangement of the broadcast screen 3, the post comment screen 4, the hash tag candidate screen 5, and the post comment writing screen 6 is not limited to the arrangement shown in FIG. 1, but may be other arrangements. Further, the arrangement of the broadcast screen 3, the post comment screen 4, the hash tag candidate screen 5, and the post comment writing screen 6 is not fixed. For example, the user can change the arrangement of these screens. Also good. Furthermore, the screen layout of FIG. 1 is a screen layout when the user changes to the posted comment mode in which posted comments are displayed or a short comment is posted. The digital broadcast is displayed on the whole of 2.

The display device 1 is connected to the Internet 7. Connected to the Internet 7 are other display devices 8, an electronic device 9 such as a personal computer, and an official homepage (hereinafter also referred to as an official HP) 10 of a broadcast program.

As shown in FIG. 2, in addition to the display unit 2, the display device 1 includes an antenna 11, a tuner 12, a signal processing unit 13, an audio processing unit 14, a speaker 15, a video processing unit 16, and a bus 17. A ROM 18, a RAM 19, a control unit 20, a remote control reception unit 21, and a transmission / reception unit 22.

The antenna 11 receives a digital broadcast signal transmitted from a broadcasting station, for example, and supplies the received signal to the tuner 12.

The tuner 12 selects a broadcast signal of a desired channel from a digital broadcast signal input via the antenna 11 and outputs it to the signal processing unit 13. The channel selection of the broadcast signal is performed, for example, when the user operates a remote controller (hereinafter referred to as a remote controller) 23 and the channel selection signal is output from the control unit 20 to the tuner 12.

The signal processing unit 13 demodulates the selected broadcast signal, and further separates the demodulated broadcast signal into an audio signal, a video signal, and program information. This program information includes, for example, information such as a program name, performers, program contents, and homepage URL information (address information). Then, the signal processing unit 13 outputs the separated audio signal to the audio processing unit 14, outputs the video signal to the video processing unit 16, and outputs the program information to the control unit 20 via the bus 17.

The audio processing unit 14 performs predetermined audio processing on the input audio signal and outputs it to the speaker 15. The speaker 15 reproduces sound based on the sound signal output from the sound processing unit 14.

The video processing unit 16 performs predetermined video processing on the input video signal and outputs it to the display unit 2. The display unit 2 displays the video signal output from the video processing unit 16 on the broadcast screen 3.

The ROM 18 stores a control program for controlling the entire display device 1, a hash tag search processing program for performing a hash tag search process described later, and the like. These programs are expanded in the RAM 19 under the control of the control unit 20.

The control unit 20 executes overall control of the display device 1 and hash tag search processing by executing the program developed in the RAM 19. The hash tag search process will be described in detail with reference to FIGS. 3 and 4 to be described later.

The remote control receiving unit 21 receives an operation instruction signal obtained by the user operating the remote control 23. The transmission / reception unit 22 that is an interface with the Internet 7 transmits / receives data to / from the Internet 7.

Next, the hash tag search process of the display device 1 configured as described above will be described.

FIG. 3 is a flowchart showing an example of the flow of hash tag search processing. This hash tag search process is performed by the control unit 20 executing the hash tag search process program recorded in the ROM 18 when the user changes to the posted comment mode while viewing a program.

First, program information separated from the digital broadcast signal is acquired (step S1), and it is determined whether or not the acquired program information includes hash tag information (step S2). If it is determined that the program information includes hash tag information, the determination is YES, and the process proceeds to step S9. As will be described later, if there is hash tag information in the program information, the hash tag information becomes the official hash tag of the program, so that the hash tag is displayed on the hash tag candidate screen 5 as one of the hash tag candidates. become.

On the other hand, if it is determined that there is no hash tag information in the program information, NO is determined, and it is determined whether or not the program information includes URL information (address information) of the official HP 10 (step S3). If it is determined that there is no URL information of the official HP 10 in the program information, the determination is NO and the process proceeds to step S6. On the other hand, if it is determined that there is URL information of the official HP 10 in the program information, the answer is YES, and the official HP 10 is connected via the Internet 7 (step S4), and it is determined whether the official HP 10 has hash tag information. (Step S5). If it is determined that there is hash tag information in the official HP 10, the answer is YES, and the process proceeds to step S9. That is, the hash tag in the official HP 10 is displayed on the hash tag candidate screen 5 as one of the hash tag candidates.

On the other hand, if it is determined that there is no hash tag information in the official HP 10, NO is determined, and a short text post search is performed on the Internet 7 using the program title as a search word (step S6). In the process of step S6, the name of the performer may be used as the search word, for example, without being limited to the program title. Next, hash tag information is extracted from the search result (step S7), and the extracted hash tag information is analyzed (step S8). In the processing of step S7 and step S8, the extracted hash tag information is analyzed and extracted as hash tag candidates in descending order of the number used as hash tags. Since the user is confused when there are too many hash tag candidates, for example, the top three types of hash tags among the hash tags obtained in step S7 and step S8 are set as hash tag candidates.

If there is hash tag information in the program information in step S2, if there is hash tag information in the official HP 10 in step S5, or if hash tag information is analyzed in step S8, the hash tag information is set as a hash tag candidate. In step S9, the set hash tag candidates are displayed on the hash tag candidate screen 5 (step S10), and the process is terminated.

The user selects the hash tag displayed on the posted comment screen 4 from the plurality of hash tag candidates displayed on the hash tag candidate screen 5. One or a plurality of hash tags may be selected. If the user does not select a hash tag, the posted comment screen 4 is displayed using the official hash tag obtained in step S2 or step S5. If there is no official hash tag, the posted comment screen 4 is displayed using the hash tag obtained most in the hash tags obtained in step S7 and step S8.

The posted comment writing screen 6 has a function of automatically adding the hash tag selected on the hash tag candidate screen 5 to the end. Further, the user can arbitrarily write a hash tag using the posted comment writing screen 6. In this case, the hash tag arbitrarily written by the user is displayed as the first hash tag candidate displayed on the hash tag candidate screen 5.

In addition, since the posted content changes one after another in real time, the hash tag obtained by the hash tag search process of FIG. 3 may leave old information. Therefore, another example of hash tag search processing that can perform hash tag search in real time will be described with reference to FIG.

FIG. 4 is a flowchart showing another example of the flow of hash tag search processing.

First, an image of a scene with a broadcast program displayed on the broadcast screen 3 is captured (step S11), and the captured image is analyzed (step S12). Next, a telop part (predetermined information) is extracted from the captured image (step S13), and it is determined whether there is a telop (step S14). If it is determined that there is no telop, the determination is no and the process proceeds to step S18. On the other hand, if it is determined that there is a telop, the answer is YES, a short text post search is performed using the telop as a keyword (step S15), and hash tag information is analyzed (step S16). The analyzed hash tag information is set as a hash tag candidate (step S17).

Next, a person part (predetermined information) is extracted from the captured image (step S18), and it is determined whether or not there is a person (step S19). If it is determined that there is no person, NO is determined and the process proceeds to step S25. . On the other hand, if it is determined that there is a person, the determination is YES, an image search is performed (step S20), and it is determined whether the person in the image has been identified (step S21). If the person in the image cannot be specified, the determination is NO and the process proceeds to step S25. On the other hand, if the person in the image can be identified, the answer is YES, and a short sentence posting search is performed using the identified person name as a keyword (step S22).

The extracted hash tag information is analyzed (step S23), and the hash tag information is set as a hash tag candidate (step S24). Finally, the hash tag candidates set in step S17 and step S24 are displayed on the hash tag candidate screen 5 (step S25), and the process ends.

3. In addition to the hash tag search process of FIG. 3, the latest hash tag candidates can be provided to the user in real time by periodically performing the hash tag search process of FIG. 4 at predetermined time intervals.

As described above, when the user wants to simultaneously enjoy the posted comments posted on the program while viewing the television broadcast, the display device 1 displays a hash tag suitable for the broadcast program as a hash tag candidate screen. 5 and can be provided to the user. As a result, the user can easily select a hash tag suitable for the program being broadcast from the hash tag candidate screen 5.

(Modification)
Ordinary programs are broadcast according to a certain rule, such as being broadcast every day at the same time zone, or broadcast at the same time zone every day of the week. Therefore, the server may manage the hashtag used by the user for displaying the posted comment screen 4 so that it can be used in the next broadcast. The function of managing the hash tag is provided to the user as one service of a so-called cloud service.

FIG. 5 is a diagram for explaining the relationship between the display device and the server that manages the hash tag. In FIG. 5, the same components as those in FIG.

As shown in FIG. 5, the display device 1 is connected to a server 30 that manages hash tags via the Internet 7. In the server 30, user management information 31, program information 32, and hash tag information 33 are recorded and managed.

For example, the hash tag information 33 extracted in the hash tag search process of the above-described embodiment and the hash tag used for displaying the posted comment screen 4 are associated with the user management information 31 and the program information 32. Registered in The hash tag registered in the hash tag information 33 is read via the Internet 7 when the user views the same program next time using the display measure 1 and is displayed on the hash tag candidate screen 5 as a hash tag candidate. Is done. The user can select the displayed hash tag candidate from the hash tag candidate screen 5 and use it as a hash tag.

It should be noted that the association between a program and a hash tag candidate can be used not only by a specific user but also by any user who can access the server 30. As a result, the hashtag used by the user A who is viewing a certain program A can be used as a hashtag candidate by the user B who is viewing the same program A.

As described above, the display device 1 according to the modification can easily obtain a hash tag optimum for the program being viewed without performing the hash tag search process of the above-described embodiment.

The program for performing the operations described above is recorded or stored in its entirety or in part as a computer program product on a portable medium such as a flexible disk or CD-ROM, or a storage device such as a hard disk. ing. The program is read by a computer, and all or part of the operation is executed. Alternatively, all or part of the program can be distributed or provided via a communication network. The user can easily implement the hash tag search process of each of the above-described embodiments by downloading the program via a communication network and installing it on a computer, or installing the program on a computer from a recording medium. it can.

In addition, each step in each flowchart in the present specification may be executed in a different order for each execution by changing the execution order as long as it is not contrary to the nature thereof.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
