Description

This application relates to a television broadcast display control device, a television broadcast display control method, and a program.

For example, in-vehicle devices capable of receiving television broadcasts have a function of displaying the time on the screen as a function of the navigation system. However, if the broadcast video data of a television broadcast includes a time display, this may be doubled with the time displayed by the navigation system. There is also a known television broadcast receiving device that displays the current time for television broadcasts that are determined not to have a time display (see, for example, Patent Document 1).

JP 2012-249143 A

In the technology described in Patent Document 1, if there is a portion of the image that has not changed for a predetermined period of time, it is determined that the time is being displayed, and if there is no portion of the image that has not changed, it is determined that the time is not being displayed. However, if there is an unchanged portion in the image that is not a time display, it may be erroneously determined that the time is being displayed when in fact the time is not being displayed, and the time may not be displayed properly. As such, there is room for improvement in the time display on television broadcast display devices.

The present invention has been made in consideration of the above, and aims to provide a television broadcast display control device, television broadcast display control method, and program that can more appropriately display the time.

[First embodiment]
(Display device for television broadcasting)
FIG. 1 is a block diagram showing an example of the configuration of a television broadcast display device 1 including a control device 40 which is a television broadcast display control device according to the first embodiment. The television broadcast display device 1 is a display device that displays television broadcasts. The television broadcast display device 1 is implemented, for example, in an electronic device mounted on a vehicle or a portable electronic device. In this embodiment, the television broadcast display device 1 is mounted on a vehicle. The television broadcast display device 1 includes an antenna 11, a tuner 12, a separation unit 13, a GNSS (Global Navigation Satellite System) receiving unit 21, a clock unit 22, a display unit 31, a speaker 32, and a television broadcast display control device (hereinafter referred to as a "control device") 40. The television broadcast display device 1 may further include a program data storage unit 33.

The television broadcast display device 1 shares the display unit 31 with other systems. In this embodiment, the television broadcast display device 1 shares the display unit 31 with other systems installed in the vehicle, such as a navigation system. The other systems have the function of displaying the current time on the display unit 31.

The antenna 11 receives broadcast data of a television broadcast. The broadcast data includes broadcast video data and broadcast audio data. The broadcast data may also include additional data such as program data. The antenna 11 outputs the received broadcast data to the tuner 12.

The tuner 12 selects and receives the broadcast data received by the antenna 11. The tuner 12 outputs the selected broadcast data to the separation unit 13.

The separation unit 13 separates the broadcast data received by the tuner 12 into broadcast video data and broadcast audio data. The separation unit 13 may separate program data from the broadcast data received by the tuner 12. The separation unit 13 outputs the broadcast video data and broadcast audio data to the control device 40. The separation unit 13 may output the program data to the control device 40.

The GNSS receiving unit 21 is composed of a GNSS receiver that receives GNSS signals from GNSS satellites. In this embodiment, the GNSS receiving unit 21 is implemented as a function of the navigation system. The GNSS receiving unit 21 outputs the received GNSS signals to the position information acquisition unit 41 of the control device 40.

The clock unit 22 is a clock that keeps track of the current time. In this embodiment, the clock unit 22 is implemented as a function of the navigation system. The clock unit 22 outputs time information of the current time to the time information acquisition unit 42 of the control device 40.

The display unit 31 is a display device shared with the navigation system. The display unit 31 is a display including, for example, a liquid crystal display (LCD) or an organic electroluminescence (EL) display. The display unit 31 can display broadcast video data of a television broadcast based on a video signal output from the display control unit 52 of the control device 40. The display unit 31 can display map video data by the navigation system.

The speaker 32 is a speaker shared with the navigation system. The speaker 32 outputs broadcast audio data of a television broadcast based on an audio signal output from the audio output control unit 53 of the control device 40.

The program data storage unit 33 is a storage device that stores program data. The program data includes data such as the program's broadcasting station, broadcast time, genre, and title. The program data may include program guide data called an EPG (Electronic Program Guide). The program data is stored according to the user's current location. The program data storage unit 33 is a storage device such as a semiconductor memory element such as a ROM (Read Only Memory) or a flash memory, or an external storage device connected via a network.

(Control device)
The control device 40 is an arithmetic processing device constituted by, for example, a CPU (Central Processing Unit) and the like. The control device 40 may be constituted by one or more devices. The control device 40 executes instructions contained in a program stored in a storage unit (not shown). If the broadcast video data includes a time display, the control device 40 stops the display of the time by the navigation system. If the broadcast video data does not include a time display, the control device 40 displays the time by the navigation system. The control device 40 determines whether or not the broadcast video data includes a time display, and switches between displaying and not displaying the time display by the navigation system.

The control device 40 has a position information acquisition unit 41, a time information acquisition unit 42, a display determination unit 43, a composite image generation unit 51, a display control unit 52, and an audio output control unit 53.

The location information acquisition unit 41 acquires location information indicating the user's current location from the GNSS receiving unit 21.

The time information acquisition unit 42 acquires time information indicating the current time from the clock unit 22.

The display determination unit 43 determines whether or not the broadcast video data has a time display at the current time based on the time information acquired by the time information acquisition unit 42.

For example, the broadcast video data often includes a time display during the morning hours or the time period from the evening until night when people return home. Such time display periods are stored in a storage unit (not shown).

The display determination unit 43 determines that a time display is present, for example, if the current time is in a time period in which the broadcast video data has a time display. The display determination unit 43 determines that a time display is present, for example, in a time period from early morning to around 9:00 a.m., or from 4:00 p.m. to around 7:00 p.m. in the evening.

The display determination unit 43 may determine whether or not the broadcast video data includes a time display at the user's current location and current time based on the location information acquired by the location information acquisition unit 41 and the time information acquired by the time information acquisition unit 42.

For example, in area A, the time is not displayed in the broadcast video data at any time, but in area B, the time is displayed in the broadcast video data during the morning time period or the time period from evening to night when the user returns home. In this case, the display determination unit 43 determines that the broadcast video data does not display the time when the user is in area A. The display determination unit 43 determines that the broadcast video data displays the time when the user is in area B and it is the morning time period or the time period from evening to night when the user returns home.

The display determination unit 43 may determine whether or not the broadcast video data includes a time display based on the location information acquired by the location information acquisition unit 41, the time information acquired by the time information acquisition unit 42, and the program data, which is detailed information about the program and is received together with the broadcast video data.

The display determination unit 43 may determine whether or not a time display is present based on at least one of the genre and title of the program included in the program data. More specifically, the display determination unit 43 may determine whether or not a time display is present based on the genre of the program. For example, if the genre of the program is a news program, the display determination unit 43 determines that a time display is present. For example, if the genre of the program is a drama, anime, or movie program, the display determination unit 43 determines that a time display is not present. The display determination unit 43 may determine whether or not a time display is present based on the title of the program. For example, if the program is a program with a specified title, the display determination unit 43 determines that a time display is present. The display determination unit 43 may determine whether or not a time display is present based on the time information and the genre of the program. For example, if the program is a news program or a morning information program from early morning to around 9:00 a.m., or from 4:00 p.m. to 7:00 p.m., the display determination unit 43 determines that a time display is present. For example, if the program is a drama, anime, or movie program that is broadcast in a time slot other than those mentioned above, the display determination unit 43 determines that there is no time display.

The display determination unit 43 may determine whether or not the broadcast video data includes a time display based on the location information acquired by the location information acquisition unit 41, the time information acquired by the time information acquisition unit 42, and the program data stored in the program data storage unit 33. The display determination unit 43 may determine whether or not the broadcast video data includes a time display based on the program data according to the user's location information and the current time.

The display determination unit 43 may determine whether or not there is a time display based on at least one of the genre and title included in the program data corresponding to the user's location information and the current time. More specifically, the display determination unit 43 may determine whether or not there is a time display based on the current time and the genre. For example, if the current time is in a time zone during which a news program is broadcast, the display determination unit 43 determines that there is a time display. For example, if the current time is in a time zone during which a drama, anime, or movie is broadcast, the display determination unit 43 determines that there is no time display.

The composite video generating unit 51 generates composite video data by combining the broadcast video data with the time information acquired by the time information acquiring unit 42. More specifically, when the display determining unit 43 determines that there is no time display, the composite video generating unit 46 generates composite video data by combining the time information. The composite video generating unit 51 combines the time information in a position that is unlikely to reduce the visibility of the broadcast video data, such as the top right, bottom right, top left, or bottom left of the broadcast video data. In this embodiment, the composite video generating unit 51 combines the time information in the bottom right of the broadcast video data.

The composite video data may be synthesized with time information that specifies at least one of the font, font size, color, and display position. For example, the composite video data may be synthesized with time information that is the same as or similar to the time display displayed in the immediately preceding broadcast video data in at least one of the font, font size, color, and display position.

Figure 2 shows an example of broadcast video data 101, in which the time of the television broadcast is displayed. A time display 103 is provided in the upper left-hand portion 102 of the broadcast video data 101. No time display is provided in the lower right-hand portion 104 of the broadcast video data 101.

Figure 3 shows an example of composite video data 110, in which the time on a navigation system is displayed. There is no time display in the upper left 102 of the broadcast video data 101 shown in Figure 3. In the composite video data 110, time information 105 acquired by the time information acquisition unit 42 is synthesized in the lower right 104 of the broadcast video data 101. By making the display position of the time display of the navigation system and the display position of the time display of the broadcast video data 101 different, it is possible to avoid the time displays overlapping and reducing visibility.

The display control unit 52 causes the display unit 31 to display the received broadcast video data. The display control unit 52 causes the display unit 31 to display the composite video data. The display control unit 52 may also display map video data using a navigation system.

The audio output control unit 53 outputs the broadcast audio data of the received television broadcast from the speaker 32.

(Processing in the control device)
Next, the method and function of the processing performed by the control device 40 will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the processing performed by the control device 40 according to the first embodiment. While the television broadcast display device 1 is running and broadcast video data is being displayed on the display unit 31, the processing of the flowchart shown in Fig. 4 is repeatedly executed.

The control device 40 acquires the current location (step S101). More specifically, the control device 40 acquires location information of the user's current location by the location information acquisition unit 41. The control device 40 proceeds to step S102.

The control device 40 determines whether the broadcast video data has a time display (step S102). More specifically, the control device 40 determines whether the broadcast video data has a time display by the display determination unit 43 based on the time information acquired by the time information acquisition unit 42. For example, the display determination unit 43 determines that the broadcast video data has a time display when the current time is in a time zone in which the broadcast video data has a time display. For example, the display determination unit 43 determines that the broadcast video data does not have a time display when the current time is in a time zone in which the broadcast video data does not have a time display. The display determination unit 43 may determine whether the broadcast video data has a time display at the user's current location and current time based on the position information and time information. The display determination unit 43 may determine whether the broadcast video data has a time display based on the position information, time information, and program data, which is detailed information about the program. If the display determination unit 43 determines that the broadcast video data has a time display (Yes in step S102), the control device 40 proceeds to step S103. If the display determination unit 43 does not determine that a time display is present (No in step S102), the control device 40 proceeds to step S104.

When it is determined that the time is displayed (Yes in step S102), the control device 40 hides the time displayed by the navigation system (step S103). More specifically, the control device 40 causes the display control unit 52 to display the broadcast video data on the display unit 31. The control device 40 causes the display control unit 52 to display, for example, the broadcast video data 101 shown in FIG. 2 on the display unit 31. The control device 40 ends the process.

If it is not determined that the time is displayed (No in step S102), the control device 40 displays the time from the navigation system (step S104). More specifically, the control device 40 uses the composite image generation unit 51 to generate composite image data by combining the broadcast image data 101 with the time information acquired by the time information acquisition unit 42. The control device 40 then causes the display control unit 52 to display the composite image data on the display unit 31. The control device 40 uses the display control unit 52 to display, for example, the composite image data 110 shown in FIG. 3 on the display unit 31. The control device 40 ends the process.

If the user has set the time display to "Hide (OFF)" in the navigation system, the process in the above flowchart will not be applied.

In addition, if the user has set the time display to "display (ON)" in the navigation system, after the time display on the navigation system is hidden in step S103, if it is determined that the time display on the broadcast video data has disappeared (No in step S102), the time display on the navigation system will be restored.

In this way, based on the time information, it is determined whether or not the broadcast video data has a time display. If it is determined that the broadcast video data has a time display, the navigation system stops displaying the time. If it is determined that the broadcast video data does not have a time display, the navigation system continues to display the time.

(effect)
As described above, in this embodiment, it is determined whether or not the broadcast video data has a time display based on the time information. If it is determined that the broadcast video data has a time display, the display of the time by the navigation system can be stopped. In this embodiment, if it is determined that the broadcast video data does not have a time display, the navigation system can display the time. This embodiment can determine whether or not the broadcast video data has a time display, and switch between displaying and not displaying the time display by the navigation system. According to this embodiment, it is possible to restrict double display of the time on the display unit 31. By restricting double display as in this embodiment, it is possible to prevent the user from feeling annoyed or uncomfortable about the time display. In this way, this embodiment can display the time appropriately.

In this embodiment, it is determined whether or not the broadcast video data has a time display based on the location information and the current time. According to this embodiment, it is possible to more appropriately determine whether or not the time display is present.

This embodiment determines whether or not the broadcast video data includes a time display based on location information, the current time, and program data. This embodiment makes it possible to more appropriately determine whether or not the time display is included.

This embodiment makes it possible to easily determine whether or not the time is displayed in a short time.

This embodiment synthesizes time information that is the same as or similar to the time display displayed in the immediately preceding broadcast video data in at least one of the following: font, font size, color, and display position. This embodiment can display the time in a manner that does not impair visibility for the user when switching the time display by the navigation system from hidden to displayed.

[Second embodiment]
A television broadcast display device 1A having a control device 40A according to this embodiment will be described with reference to Figs. 5 and 6. Fig. 5 is a block diagram showing an example of the configuration of a television broadcast display device 1A including a control device 40A according to a second embodiment. Fig. 6 is a flowchart showing an example of processing performed by the control device 40A according to the second embodiment. The television broadcast display device 1A has a basic configuration similar to that of the television broadcast display device 1 of the first embodiment. In the following description, components similar to those of the television broadcast display device 1 are given the same or corresponding reference symbols, and detailed description thereof will be omitted. The control device 40A of this embodiment differs from the first embodiment in that it has a recognition unit 44A and in the processing in the display determination unit 43A.

The time display included in the broadcast video data is a character string including numbers indicating the hour and minute of the time, such as "XX:XX" or "XX:XX". The time display may include 12-hour and 24-hour displays, such as "15:00" or "PM3:00". The time display may include characters indicating morning and afternoon, such as "AM" or "PM". The time display includes horizontal writing, vertical writing, and analog clock display. The time display may include hours, minutes, and seconds, such as "XX:XX:XX" or "XX:XX:XX". When the time display includes hours and minutes, the time display is updated every minute (60 seconds). When the time display includes hours, minutes, and seconds, the time display is updated every second.

The time display included in the broadcast video data may be, for example, a graphic that resembles an analog clock. In the case of an analog clock that includes hour and minute hands that indicate the hours and minutes, the time display is updated every minute. In the case of an analog clock that includes a second hand, the time display is updated every second.

The recognition unit 44A recognizes characters indicating the time from the broadcast video data. More specifically, the recognition unit 44A acquires the broadcast video data. The recognition unit 44A then performs character recognition processing, such as OCR (Optical Character Reader) processing, on the acquired broadcast video data to extract character information indicating the time. The recognition unit 44A outputs the recognized character information to the display determination unit 43A. Examples of character information recognized by the recognition unit 44A include "xxx:xxx", "xxx:xxx", "xxx:xxx:xxx", and "xxx:xxx:xxx".

The recognition unit 44A recognizes a graphic representing an analog clock from the broadcast video data. More specifically, the recognition unit 44A acquires the broadcast video data. The recognition unit 44A then performs image recognition processing on the acquired broadcast video data to recognize the graphic of the analog clock. The recognition unit 44A outputs the recognized graphic information to the display determination unit 43A.

The display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes over a predetermined period of time. In this embodiment, the broadcast video data is determined to have a time display when the same time display continues for a predetermined period of time in the broadcast video data. For example, when the time display includes hours and minutes, the time display changes over one minute. In this case, the display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes over one minute. When the time display includes hours, minutes, and seconds, the time display changes over one second. In this case, the display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes over one second. The display determination unit 43A determines that the broadcast video data has a time display when the numbers change over one minute or one second in a character string such as "XX:XX" or "XX:XX". The display determination unit 43A determines that the time is displayed if the position of the hands on the analog clock graphic changes every minute or every second.

For example, if letters or figures are written on a flipboard used in an information program, they will not change even after a predetermined time has passed. Also, if a character string indicating the time is written on a flipboard or the background of a broadcast studio, it will not change even after a predetermined time has passed, unlike the current time display. If the broadcast video data includes a time display that does not change over a predetermined time, the display determination unit 43A determines that the broadcast video data does not have a time display.

For example, when the channel is changed, or when a program ends and it is time to switch to the next program, the counter described below is reset and counting the specified time begins again.

Next, the method and operation of the processing performed by the control device 40A will be described with reference to FIG. 6. The processing in FIG. 6 is executed when step S103 in the flowchart shown in FIG. 4 is executed. The explanation will be given assuming that the predetermined time is one minute (60 seconds) and the predetermined time interval is one second.

The control device 40A resets the counter (step S111). The control device 40A proceeds to step S112.

The control device 40A temporarily stores the received broadcast video data (step S112). The control device 40A temporarily stores the broadcast video data in memory at a predetermined time interval, for example, at one-second intervals. The control device 40A proceeds to step S113.

The control device 40A recognizes the broadcast video data (step S113). The control device 40A recognizes the time display of the received broadcast video data using the recognition unit 44A. The control device 40A stores the recognition result in association with the broadcast video data stored in memory in step S112. The control device 40A proceeds to step S114.

The control device 40A judges whether or not the same time display as the previous time is present (step S114). The control device 40A uses the display judgment unit 43A to compare the recognition result of the broadcast video data in the current process stored in memory with the recognition result of the broadcast video data in the previous process. The current process is the latest process among the processes at a predetermined time interval. The control device 40A compares character strings recognized from the current and previous broadcast video data, such as "XXX:XX" and "XX hours XX minutes". Alternatively, the control device 40A compares the position of the hands of an analog clock figure, for example, recognized from the current and previous broadcast video data. If the display judgment unit 43A judges that the same time display as the previous time is present (Yes in step S114), the control device 40A proceeds to step S115. If the display judgment unit 43A does not judge that the same time display as the previous time is present (No in step S114), the control device 40A proceeds to step S118.

When it is determined that the same time display as the previous time is present (Yes in step S114), the control device 40A increments the counter by "1" (step S115). The increment of the counter is set corresponding to the predetermined time interval in step S112. For example, if the predetermined time interval is one second, the counter is incremented by "1".

The control device 40A determines whether the counter is 59 or greater (step S116). The control device 40A determines whether the same time display has continued for a predetermined time. If the predetermined time is one minute (60 seconds), the counter is at "59" when the same time display has continued for one minute. If the control device 40A determines that the counter is 59 or greater (Yes in step S116), it proceeds to step S117. In this case, the same time display has continued for a predetermined time, for example, 60 seconds. If the control device 40A does not determine that the counter is 59 or greater (No in step S116), it executes the process of step S112 again. In this case, the same time display has not continued for a predetermined time, for example, 60 seconds.

When it is determined that the counter is 59 or more (Yes in step S116), the control device 40A hides the time displayed by the navigation system (step S117). If the same time display continues for a predetermined time, for example, 60 seconds, the control device 40A hides the time display by the navigation system. More specifically, the control device 40A causes the display control unit 52 to display the broadcast video data on the display unit 31. The control device 40A causes the display control unit 52 to display, for example, the broadcast video data 101 shown in FIG. 2 on the display unit 31. The control device 40A ends the process.

If it is not determined that the same time display as the previous time is displayed (No in step S114), the control device 40A resets the counter (step S118). If the same time display has not continued for a predetermined period of time, for example, 60 seconds, the counter is reset. The control device 40A executes the process of step S112 again.

If the broadcast video data has a time display, the answer in step S116 becomes Yes when the same time display continues for one minute for the first time. For example, if processing is started between 7:25:00 and 7:25:59, the counter becomes "59" at 7:25:59. In this case, from "7:26", only the time display of the broadcast video data 101 is displayed. For example, if processing is started between 7:26:00 and 7:26:59, the counter becomes "59" at 7:26:59. In this case, from "7:27", only the time display of the broadcast video data 101 is displayed.

If the predetermined time interval is 5 seconds, in step S114, the counter is incremented by 5. Then, in step S116, it is determined whether the counter is 55 or greater.

For example, if a character string indicating the time is written on a flipboard or the background of a broadcast studio, the position of the character string displayed on the display unit 31 may move or the character string may disappear. For this reason, it is considered unlikely that the character string indicating the time on a flipboard or the like will be determined to continue to display the same time for a predetermined period of time, for example, 60 seconds.

In this way, if the broadcast video data includes a time display that changes at predetermined intervals, it is determined that the broadcast video data contains a time display.

As described above, this embodiment can determine that the broadcast video data contains a time display if the broadcast video data contains a time display that changes over a predetermined period of time, such as one second or one minute. This embodiment can more appropriately determine whether or not a time display is present, and can appropriately display the time.

This embodiment can suppress erroneous determination as a time display when, for example, characters or figures are written on a flipboard or the like. This embodiment can suppress erroneous determination as a time display when, for example, a character string indicating the time is written on a flipboard or the background of a broadcast studio. This embodiment can suppress erroneous determination as a time display when, for example, broadcast video data includes a still image clock display that does not display the current time.

So far, we have described the control device, television broadcast display control method, and program according to the present invention, but they may be implemented in various different forms other than the above-described embodiments.

The components of the illustrated control device, television broadcast display control method, and program are functional concepts and do not necessarily have to be physically configured as illustrated.
