It should be noted that the TV 100 may also be one of the devices constituting the home network system 200.

The home network system 200 includes a home router 210, and a part or all of the devices constituting the home network system 200 can communicate with devices outside the house via the home router 210. For example, if the moving image distribution server 300 is installed in a remote place, the smart phone 206, the PC 207, or the TV 100 can receive the moving image distributed by the moving image distribution server 300 via the home router 210.

The lighting device 201, the refrigerator 202, the washing machine 203, the air conditioner 204, the door sensor 205, and the BD video recorder 208 are so-called IoT devices. That is, the lighting device 201, the refrigerator 202, the washing machine 203, the air conditioner 204, the door sensor 205, and the BD recorder 208 have a communication function, and can use the communication function to notify other devices of events such as changes in the device state.

For example, the door sensor 205 can send a notification of the detected content when opening and closing of the door is detected. In addition, the washing machine 203 can send a notification that the washing is completed when the washing is completed. In addition, the air conditioner 204 can send a notification urging cleaning of the filter.

The system memory 110 may include a non-volatile memory that retains the firmware program and the data in a non-volatile manner, and a volatile memory that loads the firmware program or caches the data. The non-volatile memory may be, for example, ROM (Read Only Memory) or flash memory. The volatile memory may be RAM (Random Access Memory), for example. It should be noted that the examples of non-volatile memory and volatile memory are not limited to this.

The control device 101 is, for example, a processor such as a CPU (Central Processing Unit). The control device 101 can implement various functions for controlling the television 100 by executing the firmware program stored in the system memory 110. The various functions implemented by the control device 101 will be described later.

The broadcast receiving device 105 is an interface device for receiving broadcast programs transmitted by broadcast signals from a broadcast television station. Broadcast programs can also be referred to as broadcast content. The broadcast receiving device 105 receives broadcast signals by wire or wireless.

The recording device 103 is a nonvolatile memory that stores recording data of broadcast programs received via the broadcast receiving device 105. The recording device 103 may be constituted by a relatively large-capacity medium such as SSD (Solid State Drive), HDD (Hard Disk Drive), or BD (Blu-ray (registered trademark) Disc) drive. It should be noted that the example of the recording device 103 is not limited to this. It should be noted that sometimes recorded broadcast programs or recorded data of recorded broadcast programs are marked as recorded content.

The operation button 107 is a hardware button for operating the television 100. The operation button 107 can be constituted by a touch panel. The operation button 107 may include a power button, a channel operation button, or the like.

FIG. 2 is a schematic diagram showing an example of the functional configuration of the television 100 to which the broadcast receiver of the first embodiment is applied. The television 100 includes a broadcast receiving unit 10, an external input unit 11, a first display control unit 12, a second display control unit 13, and a recording control unit 14.

The broadcast receiving unit 10 can receive broadcast programs through broadcast signals. The broadcast receiving unit 10 is, for example, a broadcast receiving device 105.

The external input unit 11 can receive input signals from external devices. The external device specifically refers to a device that constitutes a part or all of the home network system 200. The input signal refers to a signal different from the broadcast signal. The input signal may include notifications of events from IoT devices. Alternatively, the input signal may include an image signal projected from the smart phone 206 or the PC 207. It should be noted that the external input unit 11 is, for example, the communication control device 104 or the external input device 102.

The first display control unit 12 can display the broadcast program received by the broadcast receiving unit 10 on the display device 108 in real time. Real-time display of broadcast programs means that the received broadcast programs are not played after being recorded, but the received broadcast programs are displayed immediately. It should be noted that there may be a delay caused by various processing such as image quality adjustment in the period from the reception of the broadcast program to the display. The first display control unit 12 displays the broadcast program in real time, so that the user can watch the broadcast program in real time.

The second display control unit 13 displays information related to the input signal on the display device 108 when the input signal is input to the external input unit 11. The information associated with the input signal is as described above.

More specifically, for example, when a notification indicating that the door sensor 205 has detected the opening and closing of the door is received as an input signal, the second display control unit 13 can indicate that the opening and closing of the door has been detected. The meaning information is displayed on the display device 108. In another example, when a notification that the washing machine 203 has completed washing is received as an input signal, the second display control unit 13 can display information indicating that the washing has been completed on the display device 108. Furthermore, in another example, when a notification of the air conditioner 204 prompting cleaning of the filter is received as an input signal, the second display control unit 13 can display the information prompting cleaning of the filter on the display device 108.

Furthermore, in another example, when an image is received as an input signal from the smart phone 206 or PC 207 due to the operation of the user of the smart phone 206 or the PC 207, the second display control unit 13 can display the received image on Display device 108.

It should be noted that the second display control unit 13 may display information associated with the input signal on the entire screen of the display device 108. Alternatively, the second display control unit 13 may display information related to the input signal on a part of the screen of the display device 108 in a small size.

In the case where the first display control section 12 is displaying a broadcast program, the second display control section 13 may stop the display of the broadcast program and display the information associated with the input signal on the entire screen. Alternatively, the second display control unit 13 may display the information associated with the input signal in a small manner such that it overlaps the broadcast program displayed in real time.

Alternatively, the second display control unit 13 may also display the information associated with the input signal in a small way such that it overlaps the broadcast program displayed in real time, and then display the information according to the remote control from the user or the operation with the operation button 107. This information is displayed on the entire screen.

Alternatively, the second display control unit 13 may also display the first information associated with the input signal in a small manner such that it overlaps with the broadcast program displayed in real time, and then operate according to the remote control from the user or the operation with the operation button 107. To display the second information associated with the input signal on the entire screen.

The first information is, for example, an icon for prompting cleaning of the filter of the air conditioner 204. If the user performs a predetermined operation in the state where the icon is displayed, the second display control unit 13 may display the description indicating the cleaning method of the filter of the air conditioner 204 on the entire screen as the second information.

The recording control unit 14 starts recording of the broadcast program when a matter that hinders the real-time display of the broadcast program occurs. In the first embodiment, the matter that hinders the real-time display of the broadcast program specifically refers to the display of information related to the input signal.

In the case where the real-time display of the broadcast program is hindered by the display of information associated with the input signal, the user is deprived of the opportunity to watch the content broadcast during the display of the information. The recording control unit 14 records the broadcast program broadcast during the period, thereby enabling the user to watch the content of the program broadcast during the period later.

It should be noted that the trigger for the start of recording of a broadcast program may be when the information associated with the input signal is displayed on a part of the screen of the display device 108, or the information associated with the input signal is displayed on the entire display device 108. On the screen, it can also be the above two. In addition, when it is determined that information associated with a certain input signal will be displayed on the display device 108, the reception of the input signal may be used as an opportunity to start recording of a broadcast program.

In addition, the timing of the start of the display of the information associated with the input signal and the timing of the start of the recording of the broadcast program do not necessarily have to be the same. There may be a time lag (time lag) required for the processing of recording start and the like between the timings of the two.

That is, as long as the recording of the broadcast program is started at the timing associated with the start of the display of the information associated with the input signal, the recording of the broadcast program can be performed in the longest possible period of the information display period. .

The display of the information associated with the input signal may be terminated by the user's operation to end the display, or may be terminated by the second display control unit 13 when a predetermined time has passed from the start of the display. Alternatively, it is also possible to end the display of the information when the event associated with the information being displayed is eliminated.

The recording control unit 14 starts the playback of the recorded content (that is, the recorded broadcast program) at the timing when the display of the information associated with the input signal ends. At this time, the user's operation for starting playback is not required.

The timing of the end of the display of the information associated with the input signal and the timing of the playback of the recorded content do not necessarily have to be the same. There may be a time difference between the timings of the two, which is necessary for the process of starting playback, etc. As long as the playback of the recorded content is started at the timing associated with the end of the display of the information by the second display control unit 13, it can be provided to the user at the earliest possible timing after the display of the information is ended. Just watch the content of the interrupted program in real time.

It should be noted that the timing of the end of the recording is arbitrary. For example, the recording control unit 14 may continue recording until the broadcast of the interrupted broadcast program in real-time display ends, or may continue recording until a predetermined time has elapsed from the end of the display of the information associated with the input signal. The recording control unit 14 may also end the recording when the free space of the recording device 103 is used up.

In addition, the recording control unit 14 may repeat the stop of recording and the restart of recording a plurality of times. For example, the recording control unit 14 may temporarily stop recording at the timing when the display of the information associated with the input signal ends, and then immediately restart recording.

In addition, the recording control unit 14 can perform recording of the broadcast program received from the broadcast receiving unit 10 while performing the broadcast of the recorded data of the broadcast program.

It should be noted that, in the first embodiment, the recording control unit 14 performs the playback of the recorded content at the same speed as the normal playback speed, that is, the progress speed of the broadcast program. After starting playback at the normal playback speed, the recording control unit 14 can change the playback speed in accordance with the user's operation. In addition, the recording control unit 14 can temporarily stop the playback and end the playback in accordance with the user's operation during the playback.

The functions of the first display control unit 12, the second display control unit 13 and the recording control unit 14 are realized by the control device 101 executing a firmware program, for example.

Alternatively, part or all of the functions of the first display control unit 12, the second display control unit 13 and the recording control unit 14 may be realized by logic circuits. Part or all of the functions of the first display control unit 12, the second display control unit 13 and the recording control unit 14 may be realized by analog circuits. Part or all of the functions of the first display control unit 12, the second display control unit 13 and the recording control unit 14 may also be implemented by FPGA (Field-Programmable Gate Array) or ASIC (Application Specific Integrated Circuit) or the like.

FIG. 3 is a flowchart showing an example of the operation of the television 100 to which the broadcast receiver of the first embodiment is applied. Here, as an example, a case where an input signal transmitted from an IoT device constituting the home network system 200 is received will be described. However, even if the input signal is an image signal sent from the smartphone 206 or the PC 207, the same operation as described below is performed.

In S101, the first display control unit 12 displays the broadcast program on the display device 108 in real time, so that the user can watch the broadcast program in real time. If the external input unit 11 receives an input signal for notifying an event from the IoT device in this state (Yes in S102), the first display control unit 12 stops the real-time display of the broadcast program (S103), and the second display control The section 13 displays the information associated with the input signal from the IoT device (in other words, the information associated with the event notified by the input signal) on the display device 108 (S104).

The information displayed on the display device 108 associated with the input signal from the IoT device is marked as an IoT screen. In addition, the screen on which the broadcast program is displayed in real time is marked as the broadcast screen. Through S103 and S104, the display content of the display device 108 is switched from the broadcast screen to the IoT screen. It should be noted that here, as an example, it is designed to display the IoT screen on the entire screen of the display device 108.

When the display content of the display device 108 is switched from the broadcast screen to the IoT screen, the recording control unit 14 starts recording of the broadcast program (S105). In recording, the received broadcast program is stored in the recording device 103 as recording data.

Next, when the second display control unit 13 ends the display of the IoT screen by some chance (S106), the recording control unit 14 starts to play the recorded content (that is, the recorded content stored in the recording device 103 is obtained by recording the broadcast program). Recording data) (S107). As a result, the content of the broadcast program is displayed on the display device 108 from the point interrupted by S104.

When the playback of the recorded content by the recording control unit 14 ends (S108), the first display control unit 12 restarts the real-time display of the broadcast program currently being received (S109). A series of actions are ended by S109.

It should be noted that in Figure 3, the following example is illustrated: when an input signal is received, the real-time display of the broadcast program is stopped, the IoT screen is displayed on the entire screen, and the recording starts. The timing of real-time display of the broadcast program, the timing of displaying the IoT screen on the entire screen, and the timing of recording start are not limited to the above examples.

For example, when an input signal for notifying an event is received, the second display control unit 13 first displays a small IoT screen associated with the input signal, such as an icon, and the broadcast program, and then superimposes it on the broadcast program. Display the IoT screen on the entire screen. In such a case, the processing of S103 by the first display control unit 12 and the processing of S105 by the recording control unit 14 may be executed when the IoT screen is displayed on the entire screen. That is, when the IoT screen is displayed so as to overlap the broadcast program to a small extent, recording is not started, and when the IoT screen is displayed on the entire screen, the stop of real-time display of the broadcast program and the start of recording can be performed. Alternatively, when a small IoT screen such as an icon associated with the input signal is displayed, the process based on S105 by the recording control unit 14 may be executed, and then, when the IoT screen is displayed on the entire screen, the first display control based on The processing of S103 performed by the section 12.

FIG. 4 is a schematic diagram for explaining an example of switching of display content realized by a series of operations in the first embodiment shown in FIG. 3. In the example shown in this figure, a broadcast plan (Schedule) is designed such that program #1 is broadcast and then program #2 is broadcast.

On the display device 108, the broadcast screen of the program #1 is initially displayed. When the TV 100 receives an event from the IoT device at time t0, the display content is switched from the broadcast screen of program #1 to the IoT screen. Then, the recording of the program #1 is started from the point p0 broadcast at the time t0 in the program #1.

The recording ends at point p1 at the end of program #1. It should be noted that, as mentioned above, the timing of the end of recording is not limited to the timing of reaching the end of the interrupted broadcast program (program #1 in this case) in real-time viewing.

The broadcast of program #2 starts after the broadcast of program #1. In this example, the display of the IoT screen continues at the timing when the broadcast of the program #2 is started.

After that, when the display of the IoT screen ends at time t1, the playback of the recorded program #1 starts. The playback starts from the point p0 of the program #1, that is, the point where the real-time viewing is interrupted. When the program #1 is broadcast to the point p1, the display content of the display device 108 is switched to the broadcast screen of the program #2 being broadcast at that moment. The user can watch the program #2 in real time from the point p2 of the program #2 that is being broadcast at the time when the broadcast of the program #1 ends after viewing the program #1 last (time-shift viewing).

Thus, according to the first embodiment, the television 100 as a broadcast receiver includes: a broadcast receiving unit 10 that receives broadcast programs through broadcast signals; an external input unit 11 that receives an input signal different from the broadcast signal from an external device; and A display control unit 12, which displays the broadcast program on the display device in real time; a second display control unit 13, which displays information indicating information associated with the input signal when the input signal is input; and video recording control The section 14 starts the recording of the broadcast program at the first opportunity associated with the start of the display of the information.

Accordingly, even if the user is obstructed in real-time viewing of the broadcast program due to the display of an unexpected screen, it is possible to later watch the content that was broadcast during the period in which the real-time viewing was obstructed.

It should be noted that the second display control unit 13 may use the input of the input signal as a trigger to perform the display set as the trigger for the start of recording, or it may perform the display set as the trigger for the establishment of certain conditions after the input signal is input. It is a display of the opportunity to start recording. That is, the second display control unit 13 does not necessarily need to perform the display that is the trigger for the start of recording immediately after the input of the input signal.

For example, when the input signal is input, the second display control unit 13 first displays the first information associated with the input signal in a small manner overlapping with the broadcast program. After that, in accordance with the input of an operation performed by the user or the like, the second display control section 13 displays the second information associated with the input signal on the entire screen. The display of this second information can be set as an opportunity to start recording. It should be noted that, of course, the display of the first information can also be set as an opportunity to start recording.

In addition, in the above description, as an example of a screen that the user does not expect, the information associated with the input signal from the IoT device and the information (ie image) generated based on the image signal projected from the smartphone 206 or PC 207 are cited. . The screen that is the trigger for the start of recording is not limited to this. In addition, the screen that triggered the start of recording may be any of these.

The user who operates the smartphone 206 or the PC 207 (marked as the first user) and the user who watches the TV 100 (marked as the second user) are sometimes the same and sometimes different. In the case where the first user and the second user are the same, even if the real-time display of the broadcast program is interrupted by projecting images from the smart phone 206 or the PC 207, the screen newly displayed by the projection does not correspond to a screen that the user does not expect.

However, when the first user is different from the second user, the image projected from the smart phone 206 or the PC 207 may be equivalent to a screen different from the second user's will. In this case, the second user's opportunity to watch the broadcast program will be deprived due to the display of undesired images.

The TV 100 is configured to start recording when an image projected from the smartphone 206 or the PC 207 is displayed. Therefore, even if the second user is obstructed in real-time viewing due to the display of the projected image under the operation of another user, You can later watch the content that was blocked during the period in which real-time viewing was blocked.

In addition, according to the first embodiment, the recording control unit 14 starts to play the recorded content at the second timing, wherein the second timing is associated with the end of the display of the information associated with the input signal.

As a result, the user can watch the content of the interrupted broadcast program without performing any special operation after the display of the information associated with the input signal ends.

It should be noted that the recording control unit 14 may display on the display device 108 a selection screen that prompts whether to start playing the recorded content after the display of the information associated with the input signal ends. In addition, after selecting to start playing of the recorded content, the recording control unit 14 starts playing.

In addition, the recording control unit 14 may be configured to be able to specify in advance from a setting screen or the like whether or not to start playback of the recorded content after the display of the information associated with the input signal ends.

(Second embodiment)

In the first embodiment, after the display of the information associated with the input signal ends, the playback of the recorded content at the normal playback speed is started. In the second embodiment, after the display of the information associated with the input signal ends, the recorded content is played in fast forward. Fast forward playback refers to playing video content at a speed faster than the normal playback speed. The television receiver to which the broadcast receiver of the second embodiment is applied is referred to as a television 100a, and the television 100a will be described.

The television 100a has the same hardware configuration and similar functional configuration as those of the television 100 described in the first embodiment. The operation of some functional components of the television 100a is different from that of the television 100. Hereinafter, the main points of matters different from the first embodiment will be described, and the description of the same matters as the first embodiment will be omitted.

FIG. 5 is a flowchart showing an example of the operation of the television 100a to which the broadcast receiver of the second embodiment is applied. Here, the case where the input signal transmitted from the IoT device constituting the home network system 200 is received similarly to the first embodiment will be described. The input signal may be an image signal sent from the smartphone 206 or the PC 207, and the same operation as described below can be performed.

In S201 to S206, the same processing as S101 to S106 is performed. When the display of the IoT screen ends in S206, the recording control unit 14 starts to fast-forward and play the recorded content, that is, the recorded data stored in the recording device 103 (S207). In S207, the recording control unit 14 performs playback at a speed faster than the normal playback speed, such as 1.2 times or 1.5 times the normal playback speed.

The recording control unit 14 continues to record the received broadcast program even during the execution of the fast forward broadcast. However, since the playback speed of fast forward playback is faster than the recording speed of the receiving broadcast program, the difference between the playback point and the recording point becomes smaller as time passes. In addition, the difference becomes the smallest value that can be played while recording. The situation that the difference between the playback point and the recording point becomes the minimum is marked as the playback point catching up with the recording point.

Following S207, the recording control unit 14 determines whether the playback point has caught up with the recording point (S208). If the playback point does not catch up with the recording point (No in S208), the process of S208 is executed again. When the broadcast point has caught up with the recording point (Yes in S208), the recording control unit 14 ends the playback of the recorded content (S209), and the first display control unit 12 restarts the real-time display of the broadcast program currently being received ( S210). A series of actions are ended by S210.

In this way, according to the second embodiment, the recording control unit 14 plays the recorded content in fast forward.

As a result, the user can watch the content that was broadcast during the interruption of real-time viewing in a short period of time, and start real-time viewing again.

In addition, according to the second embodiment, the recording control unit 14 ends the playback of the recorded content when the playback point catches up with the recording point, and the first display control unit 12 restarts the real-time broadcast of the broadcast program when the playback of the recorded content ends. display.

As a result, the user can watch the content that was broadcast during the interruption of real-time viewing in a short period of time, and start real-time viewing again.

It should be noted that the timing of the playback point catching up with the recording point and the timing of the end of the playback of the recorded content do not necessarily have to be the same. There may be a time difference between the timings of the two, which is necessary for the process of ending the playback, etc. That is, as long as the recording control unit 14 ends the playback of the recorded content at the timing associated with the situation that the playback point catches up with the recording point, it can restart the broadcast at the earliest possible timing after the playback point catches up with the recording point. Real-time display of the program is sufficient.

In addition, the timing when the playback of the recorded content ends and the timing when the real-time display of the broadcast program restarts are not necessarily the same. There may be a time difference between the two timings, which is necessary for real-time display of the restarting process, etc. That is, as long as the first display control unit 12 restarts the real-time display of the broadcast program at the timing associated with the end of the playback of the recorded content, it can restart the broadcast at the earliest possible timing after the end of the playback of the recorded content. Real-time display of the program is sufficient.

It should be noted that the recording control unit 14 may display on the display device 108 a selection screen prompting whether to start fast-forward playback of the recorded content after the display of the information associated with the input signal ends. Furthermore, after selecting to start fast-forward playback of the recorded content, the recording control unit 14 starts playing.

In addition, the recording control unit 14 may be configured to be able to specify in advance from a setting screen or the like whether or not to start fast-forward playback of the recorded content after the display of the information associated with the input signal ends.

In addition, the recording control unit 14 may be configured to be capable of pre-designating from a setting screen or the like whether or not to restart the real-time display of the broadcast program when the broadcast point catches up with the recording point. If it is set not to restart the real-time display of the broadcast program when the broadcast point catches up with the recording point, the recording control unit 14 may return the playback speed to the normal speed to continue the playback of the recorded content.

In addition, after the playback point catches up with the recording point, it is not necessary to start real-time display again immediately.

For example, when the playback point has caught up with the recording point, the recording control unit 14 may return the playback speed to the normal speed and display the meaning that the playback point has caught up with the recording point on the display device 108 using an icon or the like. When the user recognizes that the broadcast point has caught up with the recording point, the user can perform an operation of ending the broadcast and moving to the real-time display of the broadcast program at any timing.

Even when the playback point catches up with the recording point, there is a slight difference between the playback point and the recording point. Therefore, if the playback ends when the playback point catches up with the recording point and moves to the real-time display, there will be a short unviewable period. By displaying the meaning that the playback point has caught up with the recording point, the user can perform an operation for restarting real-time viewing at a timing such as when the content cannot be watched or it does not matter that it is being broadcast.

(Third embodiment)

In the third embodiment, after the display of the information associated with the input signal ends, the recorded content is played in fast forward. The playback speed is calculated so that the playback point catches up with the recording point at the broadcast end time of the interrupted broadcast program displayed in real time, and the playback speed is obtained by calculation during fast forward playback. The television receiver to which the broadcast receiver of the third embodiment is applied is referred to as a television 100b, and the television 100b will be described.

The television 100b has the same hardware configuration and similar functional configuration as those of the television 100 and the television 100a. The operation of some functional components of the television 100b is different from that of the television 100 or the television 100a. Hereinafter, the description will be focused on matters that are different from the first embodiment and the second embodiment, and the description of the same matters as the first embodiment or the second embodiment will be omitted.

FIG. 6 is a flowchart showing an example of the operation of the television 100b to which the broadcast receiver of the third embodiment is applied. Here, as an example, a case where an input signal transmitted from an IoT device constituting the home network system 200 is received will be described. However, even if the input signal is an image signal sent from the smartphone 206 or the PC 207, the same operation as described below is performed.

In S301 to S306, the same processing as S101 to S106 is performed. When the display of the IoT screen ends in S306, the recording control unit 14 calculates the playback speed that causes the playback point to catch up with the recording point at the broadcast end time of the interrupted broadcast program in real-time display (S307).

It should be noted that the recording control unit 14 may calculate the playback speed on the premise that playback is performed at a fixed playback speed. Alternatively, the recording control unit 14 may also determine the playback speed of each time interval on the premise that the playback speed is changed stepwise in the following manner, where the method means that playback is performed at 1.5 times speed in a certain time interval and the next Play at 1.2 times speed in the time interval. The length of each time interval can also be different. The playback speed can be selected from a fixed value of 1 or more, or any value in the continuous value can be selected. The recording control unit 14 calculates the playback speed so that the playback point catches up with the recording point at the time the broadcast ends. Calculating the playing speed may include calculating the playing speed of each time interval or calculating the length of each time interval.

Following S307, the recording control unit 14 starts to fast-forward playing the recorded content, that is, the recorded data stored in the recording device 103 (S308). In fast forward playback, the playback speed calculated by S307 is applied.

And, in S309 to S311, the same processing as S208 to S210 is executed, thereby ending a series of actions.

In this way, according to the third embodiment, the recording control unit 14 controls the broadcast speed so that the timing of the broadcast point catching up with the recording point coincides with the broadcast end time of the broadcast program.

In this way, the user can quickly watch the content of the broadcast program whose real-time viewing is interrupted, and can watch other programs that follow the broadcast program in real time from the beginning.

It should be noted that the timing of the broadcast point catching up with the recording point is not necessarily the same as the broadcast end time of the broadcast program. There may be a slight time difference between the timing of the broadcast point catching up with the recording point and the broadcast end time of the broadcast program. By controlling the broadcast speed so that the timing associated with the broadcast point catching up with the recording point coincides with the broadcast end time of the broadcast program, real-time viewing can be restarted at a timing close to the broadcast end time of the broadcast program. .

It should be noted that when fast forward playback is interrupted and restarted due to a user's operation, or fast forward and fast forward are stopped, the recording control unit 14 may also execute the processing of S307 and S308 each time. Correct the playback speed.

(Fourth embodiment)

In the event that the broadcast point does not catch up to the recording point until the end of the broadcast of the broadcast program (marked as the first program), watch from the beginning the program that continues the first program and the next broadcast (marked as the first program). The second program) will be deprived of the opportunity. In the fourth embodiment, by continuing to record the second program when the above-mentioned situation occurs, the second program can be watched from the beginning.

The television receiver to which the broadcast receiver of the fourth embodiment is applied is referred to as a television 100c, and the television 100c will be described.

The television 100c has the same hardware configuration and similar functional configuration as those of the television 100, the television 100a, and the television 100b. The operation of some functional components of the television 100c is different from that of the television 100, the television 100a, or the television 100b. Hereinafter, the description will be focused on matters that are different from the first, second, and third embodiments, and descriptions of the same matters as the first, second, or third embodiments will be omitted.

FIG. 7 is a flowchart showing an example of the operation of the television 100c to which the broadcast receiver of the fourth embodiment is applied. Here, as an example, a case where an input signal transmitted from an IoT device constituting the home network system 200 is received will be described. However, even if the input signal is an image signal sent from the smartphone 206 or the PC 207, the same operation as described below is performed.

In S401 to S406, the same processing as S101 to S106 is performed. It should be noted that in the description of this figure, the broadcast program whose real-time display is interrupted due to S404 is marked as the first program.

When the display of the IoT screen ends in S406, the recording control unit 14 determines whether the broadcast point will catch up with the recording point before the broadcast end time of the first program (S407). In S407, the judgment is made on the premise that the fast-forward playback has been performed.

In the case where the broadcast point does not catch up to the recording point until the broadcast end time (No in S407), the recording control unit 14 displays a list of other programs that started broadcasting until the broadcast point catches up with the recording point on the display Device 108 (S408). The user can perform an operation of selecting a program from the displayed list.

It should be noted that the recording control unit 14 may display all the programs that started broadcasting until the broadcast point catches up to the recording point in the list, or may display a part of the programs that start broadcasting until the broadcast point catches up to the recording point in the list. The recording control unit 14 may also display only programs broadcast by a specific type of broadcasting among multiple types of broadcasting such as satellite broadcasting and terrestrial broadcasting. The recording control unit 14 may also display only programs broadcast on a specific channel. The recording control unit 14 may also display only pre-registered types of broadcasts or programs broadcast through pre-registered channels. The registration of the broadcast type or channel can be performed by the user. In addition, the control device 101 may determine the type of broadcast or the channel through machine learning or the like and register it.

Following S408, when receiving a designation for a program in the list from the user (S409), the recording control unit 14 stores the designated program and starts fast forwarding of the first program (more precisely, the recording data of the first program) Play (S410). It should be noted that the program designated in S409 is marked as the second program.

When the broadcasting of the first program ends (S411), the recording control unit 14 starts to record the second program that is subsequently broadcast (S412). It should be noted that when there is a time slack from the end of the broadcasting of the first program to the start of the broadcasting of the second program, the recording control unit 14 may also end the recording of the first program and then start the broadcasting of the second program. Start the recording of the second program at the right time.

When the fast-forward playback of the first program ends (S413), the recording control unit 14 starts the fast-forward playback of the second program (more precisely, the recording data of the second program) (S414).

Then, the recording control unit 14 determines whether the broadcast point has caught up with the recording point (S415). If the playback point does not catch up with the recording point (No in S415), the process of S415 is executed again. When the broadcast point catches up with the recording point (Yes in S415), the recording control unit 14 ends the playback of the second program (S416), and the first display control unit 12 starts real-time display of the second program currently being received (S417). Then, the series of actions ends.

In the determination process of S407, if it is determined that the broadcast point will catch up with the recording point by the broadcast end time of the first program (YES in S407), the recording control unit 14 starts fast-forward playback of the first program (S418) . Then, the recording control unit 14 determines whether the broadcast point has caught up with the recording point (S419). If the playback point does not catch up with the recording point (No in S419), the process of S419 is executed again. In the case where the broadcast point has caught up with the recording point (Yes in S419), the recording control unit 14 ends the broadcast of the first program (S420), and the first display control unit 12 restarts the display of the first program currently being received. Real-time display (S421). A series of actions are ended by S421.

In this way, when it is assumed that there is a situation in which the broadcast point does not catch up with the recording point until the end time of the broadcast of the first program, the recording control unit 14 can display a list of other programs that have started until the broadcast point catches up with the recording point and receive the following information. Designation of a program (second program) that you want to record.

Thus, the user can watch the second program from the beginning.

It should be noted that the timing of displaying the list of programs starting until the broadcast point catches up with the recording point is not limited to the above-mentioned timing. The recording control unit 14 may display the list at a timing earlier than the broadcast end time of the program being recorded by a predetermined time, for example.

In addition, the recording control unit 14 may display the programs that started after the broadcast point catches up with the recording point together with the above-mentioned list.

In addition, the recording control unit 14 may also display programs starting within a predetermined time from the broadcast end time of the first program, regardless of whether the broadcast point catches up with the recording point or not, along with the list.

(Fifth Embodiment)

In the first to fourth embodiments, as an example of a matter that hinders the real-time display of a broadcast program, a matter of displaying information related to an input signal has been described. The matter that hinders the real-time display of the broadcast program is not limited to this.

For example, the broadcast receiver of the embodiment may have an alarm function and a timer function. The alarm information issued by the alarm function or the timer information indicating that the reserved time issued by the timer function has come is displayed on the display device 108 via the second display control unit 13. Such alarm information or timing information may hinder the real-time display of the broadcast program at a timing that the user does not expect. The recording control unit 14 may start recording in the same manner as when the information related to the input signal is displayed when the alarm information or the timer information is displayed.

That is, the broadcast receiver of the embodiment can display the alarm information or the timer information as a screen that prevents the real-time display of the broadcast program when the alarm information or the timer information is issued. In addition, the broadcast receiver of the embodiment may perform the operations described in the first to fourth embodiments when the screen is displayed, as in the case where the information related to the input signal is displayed.

In addition, in the first to fourth embodiments, the input signal is input from the IoT device constituting the home network system 200 to the broadcast receiver of the embodiment. The input signal may also be input from a device installed in a network outside the house, which is different from the home network system 200.

As an example, an IoT server is installed in the network outside the house. The IoT devices constituting the home network 200 may also transmit input signals to the broadcast receiver of the embodiment via the IoT server.

In another example, the IoT server collects the status of the devices in the home network system 200 via the Internet or the like. In addition, the IoT server can transmit an input signal to the broadcast receiver of the embodiment when the collected result satisfies a predetermined condition. The input signal may be, for example, a signal for notifying information about disasters occurring in the residential area as an event.

In another example, the IoT server may transmit the input signal to the broadcast receiver of the embodiment regardless of the state of the device in the home network system 200.

In the broadcast receiver of the embodiment, when an input signal is received from the IoT server, the second display control unit 13 displays information associated with the input signal from the IoT server.

Reservation recording is a mode for recording a program that has been reserved by the user in advance. Automatic recording is a mode in which programs selected through mechanical learning or the like are recorded without any special operation by the user. The fast recording is a mode in which the user performs a recording operation during the real-time viewing of the broadcast program to start recording the broadcast program from the point where the recording operation is performed.

You can also set the priority order for the above-mentioned multiple modes. For example, consider the case where the priority is "reserved recording>backup recording>fast recording=automatic recording". In such a case, the recording control unit 14 may continue to perform backup recording until the remaining capacity is used up, wherein the remaining capacity is the free capacity of the recording device 103 minus the capacity required for the scheduled recording that has been set And get the capacity. Furthermore, when the remaining capacity is used up, if the recording data recorded by quick recording or automatic recording is stored in the recording device 103, the recording control unit 14 may delete the recording data recorded by quick recording or automatic recording. , Use the capacity released by the deletion to the backup video.

It should be noted that the above three modes except for backup video are just an example. The broadcast receiver can have any mode other than backup recording. In addition, the priority order of each mode is not limited to the above-mentioned order. The behavior when the free capacity of the recording device 103 is used up can be arbitrarily set.
