Description

Display device {Display device}

The present invention relates to a display device, and more particularly, to a display device capable of providing recommended content.

In recent years, digital TV services using wired or wireless communication networks have become widespread. Digital TV services can provide a variety of services that were not available with existing analog broadcasting services.

For example, IPTV (Internet Protocol Television), a type of digital TV service, and smart TV service provide interactivity that allows users to actively select the type of program to watch, the viewing time, etc. Based on this interactivity, IPTV and smart TV services can also provide various additional services, such as Internet search, home shopping, and online games.

Meanwhile, recently, technology to provide recommended content on TV for the convenience of users is being studied. Such recommended content is provided based on the program broadcast schedule included in the EPG (Electronic Program Guide). The EPG includes program broadcast time and content, performer information, and additional information. For example, recommended content is provided when an advertisement video is displayed based on the program broadcast time of the PG.

However, there are often cases where the actual program broadcast is not broadcast at the program broadcast time included in the EPG. For example, even if a sports broadcast is broadcast at the beginning of the broadcast time included in the EPG, if the sports game is extended to overtime or delayed due to rain, the actual sports broadcast ends much later than the end time of the broadcast time included in the EPG. For example, if a special live broadcast that is not included in the EPG is urgently scheduled, the special live broadcast is broadcast separately from the EPG.

As shown in Fig. 5, three program broadcasts (A1, A2, A3) are broadcast, and two advertisement videos (B1, B2) are broadcast between these program broadcasts (A1, A2, A3). That is, the A1 program broadcast is broadcast, and the B1 advertisement video is broadcast. The A2 program broadcast is broadcast, and the B2 advertisement video is broadcast. The A3 program broadcast is broadcast, and the B3 advertisement video is broadcast.

However, due to various circumstances such as extended play or urgent special live broadcasts, the actual broadcast time of a program may be longer than the broadcast time of the program according to the broadcast schedule information of the EPG.

For example, the broadcast time of an A1 program broadcast according to the EPG is t11, while the broadcast time of an actually broadcast A1 program broadcast is t12, which is greater than t11. For example, the broadcast time of an A3 program broadcast according to the EPG is t31, while the broadcast time of an actually broadcast A3 program broadcast is t32, which is greater than t31. The broadcast time of an A2 program broadcast according to the EPG (t21) and the broadcast time of an A2 program broadcast actually broadcast (t22) are the same.

In this case, if the time of providing the advertisement broadcast is determined according to the broadcast schedule information of the EPG, the recommended content is provided at the time t3 after the end time (t1) of the A1 program broadcast according to the broadcast schedule information of the EPG. However, the time t3 when the recommended content is provided is before the A1 program broadcast actually ends being broadcast on the display device, which corresponds to the time while the actual A1 program broadcast is in full swing. Accordingly, there is a problem that the recommended content is provided during the A1 program broadcast that is actually being broadcast, thereby interrupting the viewer's viewing of the A1 program broadcast or reducing their sense of immersion. The recommended content is also provided while the A3 program broadcast is in full swing, which causes problems of interrupting viewing and reducing their sense of immersion.

The present invention provides a display device capable of adaptively providing recommended content according to the actual broadcasting situation of a program broadcast.

The present invention provides a display device capable of improving the accuracy of the time at which recommended content should be provided, thereby eliminating viewing inconvenience for viewers.

The present invention provides a display device capable of providing recommended content without disturbing the immersion of a viewer watching a program broadcast.

According to an embodiment of the present invention, a display device includes a display unit that displays a broadcast image; and a control unit that analyzes the broadcast image based on a captured screen of the broadcast image and controls the display unit to display recommended content if the broadcast image is not a program broadcast image as a result of the analysis.

According to the present invention, in cases where the broadcast time of a program broadcast image is extended due to circumstances of a broadcaster or a program broadcast not included in an EPG is urgently scheduled and broadcast, the recommended content is displayed at a time other than the broadcast time of the program broadcast image or the urgently scheduled program broadcast, thereby adaptively providing the recommended content according to the actual broadcast situation of the program broadcast, thereby improving the convenience of the viewer by recommending a variety of recommended content to the viewer without disturbing the viewer's viewing immersion.

According to the present invention, based on identification information acquired from a captured screen of a broadcast video, it is determined that the broadcast video is not a program broadcast video, and when the broadcast video is not a program broadcast video, recommended content is displayed, thereby helping the viewer to become more immersed in the program broadcast video.

According to the present invention, it is possible to improve the accuracy of the timing of providing recommended content by obtaining that a broadcast video is not a program broadcast video based on identification information obtained from a captured screen of the broadcast video and displaying recommended content when the broadcast video is not a program broadcast video.

FIG. 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on the display unit (180).

The user can move the remote control device (200) up and down, left and right, or rotate it. The pointer (205) displayed on the display unit (180) of the display device (100) corresponds to the movement of the remote control device (200). This remote control device (200) can be called a space remote control because the pointer (205) moves and is displayed according to the movement in 3D space, as shown in the drawing.

Figure 4 (b) exemplifies that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display unit (180) of the display device (100) also moves to the left correspondingly.

Information about the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the display device (100).

A log acquisition model or log acquisition engine for executing such a deep learning tool may be provided. The identifier log acquisition unit can acquire identifier log information based on characters, shapes, pictures, formulas, characters, etc. included in the captured screen.

The broadcast image judgment unit (1730) can obtain or determine whether the broadcast image is not a program broadcast image based on the identifier logo information. For example, in the case where the broadcast image is not a program broadcast image, there are advertisement images or trailer broadcasts, but this is not limited thereto. In the embodiment, any broadcast image that is not a program broadcast image can be considered not a program broadcast image.

As will be explained later, program broadcast videos can include main videos and ending videos. The main video is the actual content video of the program broadcast, and the ending video can be a video related to the end of the program broadcast. For example, videos related to the end can include a cast list video, a video of a filmed episode, and a preview video of the next episode.

The broadcast image judgment unit (1730) can obtain or determine whether the broadcast image is an advertisement image or the end image of a program broadcast image. The broadcast image judgment unit (1730) can obtain or determine whether the broadcast image displayed on the display unit (180) changes from an advertisement image to a program broadcast image. When the control unit (170) changes from an advertisement image to a program broadcast image, the control unit (170) can obtain the display time or provision time of the recommended content provided during the broadcast of the advertisement image. For example, when the control unit (170) changes from an advertisement image to a program broadcast image, the control unit (170) can block the recommended content from being supplied to the display unit (180). For example, when the control unit (170) changes from an advertisement image to a program broadcast image, the control unit (170) can control the display unit (180) so that the recommended content provided to the display unit (180) is not displayed on the screen.

The content recommendation unit (1740) can obtain recommended content to be displayed when it is not a program broadcast video. The control unit (170) can display the obtained recommended content on the display unit (180) when it is not a program broadcast video. The content recommendation unit (1740) can obtain recommended content based on the viewer's viewing pattern. The content recommendation unit (1740) can obtain recommended content based on popular channel information. The content recommendation unit (1740) can obtain recommended content based on the viewer's viewing pattern and popular channel information. The content recommendation unit (1740) can obtain recommended content including information that draws the viewer's attention or gently induces a selection, such as nudge information or information that can be helpful or guide the viewer. Recommended content may include, for example, a series of dramas tailored to the user's viewing pattern, a series of programs with the highest viewership ratings, a series of videos related to user-specified keywords, etc.

Meanwhile, the control unit (170) can obtain the display time of the recommended content depending on whether the broadcast video is the main video of the program broadcast video, the ending video of the program broadcast video, or an advertisement video.

The control unit (170) can display recommended content on the display unit (180) if the broadcast video is not a program broadcast video. For example, the control unit (170) can display recommended content on the display unit (180) if the broadcast video is the end video of a program broadcast video. For example, the control unit (170) can display recommended content on the display unit (180) if the broadcast video is an advertisement video.

Advertisement videos can be broadcast before or after a program is broadcast. Advertisement videos can be broadcast during a program, which can be called mid-program advertisement videos. At least one mid-program advertisement video can be shown during a program.

In an embodiment, recommended content may be displayed when the broadcast video is not only an advertisement video before or after the program broadcast, but also at least one mid-roll advertisement video broadcast during the program broadcast. Different recommended content may be displayed for the advertisement video before the program broadcast, the advertisement video after the program broadcast, and the mid-roll advertisement video.

If the control unit (170) determines that the broadcast video displayed on the display unit (180) has changed from an advertisement video to a program broadcast video as a result of the determination of the broadcast video determination unit (1730), the control unit (170) can control the display unit (180) so that the recommended content displayed during the advertisement video time is not displayed. In other words, the control unit (170) can block the recommended content obtained from the content recommendation unit (1740) from being provided to the display unit (180) so that the recommended content is not displayed on the screen.

In FIG. 6, the components in the control unit (170) are illustrated as being operated in the order of a screen capture unit (1710), an identifier logo acquisition unit (1720), a broadcast image judgment unit (1730), and a content recommendation unit (1740), and the content recommendation unit (1740) is operated last. In contrast, the content recommendation unit (1740) can obtain the corresponding recommended content in advance regardless of the operations of the screen capture unit (1710), the identifier log acquisition unit, and the broadcast image judgment unit (1730). For example, when the content recommendation unit (1740) recognizes that a specific program broadcast is displayed on the display unit (180), it can obtain recommended content to be displayed after the specific program broadcast, and the obtained recommended content can be displayed when it is recognized that it is not a specific program broadcast.

A method for providing recommended content is described with reference to FIGS. 7 to 15.

FIG. 7 is a flowchart illustrating a method for providing recommended content in a display device according to an embodiment of the present invention.

Referring to FIG. 1, FIG. 6, and FIG. 7, the control unit (170) can control the display unit (180) to display a broadcast image (S11). As shown in FIG. 8, the control unit (170) can display, for example, a program called “Running Man” on the display unit (180).

The control unit (170) can obtain a capture screen from a broadcast image displayed on the display unit (180) (S13). Specifically, the screen capture unit (1710) can obtain a capture screen from a broadcast image displayed on the display unit (180).

The control unit (170) can analyze the broadcast image based on the captured screen (S15). Specifically, the identifier logo acquisition unit (1720) can acquire identifier logo information from the captured screen.

The identifier logo information may include content provider logo information or identification information of a program broadcast video.

Broadcast video may include program broadcast video. Program broadcast video may include main video and ending video.

As illustrated in FIG. 9, the control unit (170) can obtain, for example, the broadcasting station logo “SBS” as content provider logo information (301) from the capture screen of the main image of the program broadcast image. As illustrated in FIG. 9, the control unit (170) can obtain, for example, the program broadcast name “Running Man” as the program broadcast image identification information (302) from the capture screen of the main image of the program broadcast image.

As shown in Fig. 10, the control unit (170) can obtain, for example, the cast list information (303) of a broadcast program from the capture screen of the main image of the program broadcast image.

As illustrated in FIG. 11, the control unit (170) cannot obtain identifier logo information from the capture screen of the advertisement video, for example, if it is an advertisement video. That is, in the case of an advertisement video, since identifier logo information is not displayed in the advertisement video, the control unit (170) can obtain identifier logo information from the capture screen of the advertisement video. That is, as illustrated in FIG. 11, in the advertisement video, a blank area (305) where identifier logo information is not displayed may be positioned corresponding to an area where identifier logo information is positioned in the program broadcast, for example, the upper right side of the capture screen.

Referring again to FIG. 7, the control unit (170) can obtain or determine whether the broadcast image is a program broadcast image based on the image analysis result for the captured screen (S17). Specifically, the broadcast image determination unit (1730) can obtain or determine whether the broadcast image is a program broadcast image based on the identifier log information obtained from the captured screen.

If the broadcast video is a program broadcast video, the broadcast video judgment unit (1730) can move to S11 and display the broadcast video on the display unit (180).

The control unit (170) can control the display unit (180) to display recommended content when the broadcast image is not a program broadcast image (S19). Specifically, the content recommendation unit (1740) can obtain recommended content to be displayed when the broadcast image is not a program broadcast image based on at least one of viewing pattern information and popular channel information. The control unit (170) can display recommended content obtained from the content recommendation unit (1740) when the broadcast image is not a program broadcast image.

For example, in the case where the broadcast video is not a program broadcast video, there may be an advertisement video or a trailer broadcast, but this is not limited thereto. Accordingly, the control unit (170) can display recommended content when the broadcast video is an advertisement video or a trailer broadcast.

As illustrated in FIG. 12, the control unit (170) may display recommended content on an area (310) of the screen of the advertisement video when the broadcast video is an advertisement video. The area (310) may be named a recommended content display area. For example, information about at least one program broadcast to be displayed after the program broadcast that was displayed before the advertisement video may be displayed on an area (310) of the screen of the advertisement video. The information about at least one program broadcast may be displayed as text and/or thumbnail images, etc. on an area (310) of the screen of the advertisement video. For example, as illustrated in FIG. 12, the text “How about the ‘XXX’ entertainment show next?” and a thumbnail image related to the recommended entertainment show may be displayed on an area (310) of the screen of the advertisement video.

FIG. 13 is a flowchart illustrating a method for blocking the display of recommended content when changing from an advertisement video to a program broadcast video in a display device according to another embodiment of the present invention. FIG. 13 can proceed from S17 of FIG. 7.

Referring to FIG. 1 and FIG. 6 to FIG. 13, the control unit (170) can obtain or determine whether the broadcast image displayed on the display unit (180) is not a program broadcast image, and if not a program broadcast, can obtain or determine whether the broadcast image is an advertisement image. If the broadcast image is an advertisement image, the control unit (170) can control the display unit (180) to display the advertisement image (S21).

The control unit (170) can obtain whether the advertisement video is changed to a program broadcast video (S23). A content provider providing a program broadcast video can transmit an advertisement video to a display device (100) before transmitting the corresponding program broadcast video. The control unit (170) can control the display unit (180) to display the advertisement video received from the corresponding content provider. The control unit (170) can receive the corresponding program broadcast video after reception of the advertisement video is terminated. By obtaining reception of the corresponding program broadcast video, the control unit (170) can obtain or determine whether the advertisement video is changed to a program broadcast video.

If the control unit (170) does not change from an advertisement video to a program broadcast video, it can move to S21 and display the advertisement video on the display unit (180).

The control unit (170) can control the display unit (180) to block recommended content when changing from an advertisement video to a program broadcast video (S25). For example, the control unit (170) can block the supply of recommended content to the display unit (180) when changing from an advertisement video to a program broadcast video. For example, when changing from an advertisement video to a program broadcast video, the control unit (170) can supply recommended content to the display unit (180), but control the display unit (180) to not display the supplied recommended content on the screen.

Fig. 14 is a flowchart illustrating a method for displaying recommended content when the video is the end video of a program broadcast video in a display device according to an embodiment of the present invention. Fig. 14 can proceed from S17 of Fig. 7.

Referring to FIGS. 1, 6 to 12 and 14, the control unit (170) can obtain or determine whether a broadcast image displayed on the display unit (180) is not a program broadcast image, and if it is a program broadcast image, can obtain or determine whether the program broadcast image is a main image (S31).

The control unit (170) can move to S31 when the corresponding program broadcast video is the main video.

The control unit (170) can obtain or determine whether the program broadcast video is an ending video if the program broadcast video is not the main video (S33).

The control unit (170) can move to S31 if the corresponding program broadcast video is not an ending video.

The control unit (170) can control the display unit (180) to display recommended content when the corresponding program broadcast video is a finished video (S35). The control unit (170) can obtain or determine that the corresponding program broadcast video is a finished video by obtaining the cast list information from the captured screen obtained from the corresponding program broadcast video.

As illustrated in Fig. 15, when the control unit (170) obtains cast list information (303) from a captured screen obtained from a program broadcast video, the control unit (170) may control the display unit (180) to regard the program broadcast video as an ending video and display recommended content. The recommended content may be displayed in a recommended content display area (310) on the screen of the ending video of the program broadcast video.

The above description is merely an illustrative description of the technical idea of the present invention, and those skilled in the art will appreciate that various modifications and variations may be made without departing from the essential characteristics of the present invention.
