It is an example of a display of the operation screen of the terminal device 1 in OD playback mode. In addition to playback, fast forward, and rewind, for example, if the time when the channel is switched is stored, it can be viewed from the switched position. You can also watch it from the beginning or watch it later.

The channel switching notification is transmitted from the video display device 3. For example, when a channel switching by a terminal device 1 different from the terminal device 1 that switched the channel of the video display device 3 occurs, the video display device 3 transmits a channel switching notification as status information.

When the channel switching notification has not been received, the terminal device 1 repeats the processes from step S1203.

Thus, for example, when the terminal device 1a turns on the video display device 3 by remote control, the video display device 3 is turned on.

Next, when the terminal device 1a performs channel switching of the video display device 3 by remote control,
The channel of the video display device 3 is switched as instructed. When another terminal device 1b switches the channel of the video display device 3 by remote control, the channel of the video display device 3 is switched as instructed, and a channel switching notification is transmitted as status information to the terminal device 1a.

When the channel switching notification is received, the terminal device 1a searches the content of the channel before switching to the terminal device 1b from the VOD.

Note that the user may be asked for permission before searching for and displaying the content. FIG.
) Is a display example of the screen of the terminal device 1 at this time. For example, the terminal device 1 may be set to the VOD playback mode only when the “Yes” button displayed on the screen is pressed.

With the above configuration, the fourth embodiment of the present invention can achieve the same effects as those of the first embodiment.

Further, when the channel of the video display device set by remote control from the terminal device is switched by another terminal device, the content displayed on the video display device before the switching is searched from the VOD, and the terminal device is searched. Can be displayed. Even if the channel set by the user is switched by another user, the user can search for the VOD without any particular operation and view it on the terminal device at hand, thereby preventing the content from being overlooked.

FIG. 14 is a flowchart showing the processing of the video display apparatus according to the sixth embodiment of the present invention.
This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

Steps S1401 to S1407 are the same as steps S601 to S607 in FIG.

Steps S1408 to S1409 are the same as steps S908 to S909 in FIG.
Steps S1412 to S1413 are the same as steps S912 to S913 in FIG.

In step S1410, it is confirmed whether another command has been received. If another command is received, the process proceeds to step 1411. If not received, the process proceeds to step S1414. Step S1411 is the same as step S611 in FIG.

In step S1414, it is confirmed whether or not the content after the channel switching is completed. If the content after the channel switching is completed, the process proceeds to step S1415, and the video display device 3 reproduces the recorded content. If the content after the channel switching has not ended, the video display device 3 repeats the processes from step S1404.

Thus, for example, when the terminal device 1a turns on the video display device 3 by remote control, the video display device 3 is turned on.

Next, when the terminal device 1a performs channel switching of the video display device 3 by remote control,
The channel of the video display device 3 is switched as instructed. When another terminal device 1b switches the channel of the video display device 3 by remote control, the channel of the video display device 3 is switched as instructed, and a channel switching notification is transmitted as status information to the terminal device 1a.

Further, the video display device 3 records the content of the channel before switching to the terminal device 1b in the storage unit 35, and reproduces it when the content after the channel switching ends.

With the above configuration, the sixth embodiment of the present invention can achieve the same effects as the first embodiment.

Furthermore, when the channel of the video display device set by remote control from the terminal device is switched by another terminal device, the content displayed on the video display device before switching is recorded on the video display device, and the channel When the content after switching ends, it is played back. Even if the channel set by the user is switched by another user, the user can record and reproduce the image on the video display device without any particular operation, so that the content can be prevented from being overlooked.

FIG. 15 is a flowchart showing the operation of the terminal device 1 when the video display device 3 is remotely controlled.

In step S1501, the terminal device 1 determines the video display device 3 based on the user's operation.
It waits for the activation of application software (hereinafter referred to as “operation application”) for performing remote control.

5 and 23 are various display examples of the touch panel type display unit 22 of the terminal device 1. FIG.
(A) shows a menu screen in which various types of application software are arranged on the terminal device 1. When the “TV” button displayed on the touch panel is pressed by the user, the operation application is activated.

In step S1502, based on the user operation, the terminal device 1 selects the video display device 3 to be subjected to remote control. FIG. 5B is a display example of a selection screen when there are two video display devices 3 that can be selected as targets for remote control. Here, “TV A”
Shall be selected.

When the video display device 3 to be remotely controlled is selected, the terminal device 1 displays the video display device 3.
Various instructions that can be transmitted are displayed. FIG. 23 is a display example of the operation screen of the video display device 3 at that time.

Next, in step S1503, the terminal device 1 confirms whether or not the user has performed an operation for terminating the operation application. When the user performs an operation for ending the operation application such as pressing the “end” button displayed on the terminal device 1, the terminal device 1 returns to the step of displaying the menu screen.

In step S1504, the terminal device 1 confirms whether the user has pressed the power button. When the user presses the “power” button displayed on the terminal device 1, the terminal device 1
A power command is transmitted to the video display device 3 (step S1505), and the processes from step S1503 are repeated.

If the user has not pressed the “power” button displayed on the terminal device 1, step S15 is performed.
In 06, the terminal device 1 confirms whether or not the user has pressed the miss-prevention mode button. When the user presses the “prevent overlooking” mode button displayed on the terminal device 1, the terminal device 1 switches on / off of the overlooking prevention mode (step S1507). If the miss prevention mode is on, the miss prevention mode is turned off in step S1508, and if it is off, the miss prevention mode is turned on in step S1509. Then, the processes from step S1503 are repeated.

The miss-prevention mode is, for example, CM (Commercial Message, hereinafter “
Commercial)) to prevent overlooking of the TV program of the original channel after the end of the video of the advertising means accompanying the TV program and the notification means such as the notice of the program. Even if the user switches the channel after the start of the video, the channel is switched to the original channel according to the end timing of the video. Thereby, for example, even if the user is watching a TV program on channel A and the user switches to channel B or channel C after the TV program is switched to commercial, the commercial on channel A ends and the TV program is changed to a TV program. The display of the video display device 3 is switched to channel A in accordance with the switching timing.

If the user has not pressed the “prevent overlook” mode button displayed on the terminal device 1, in step S1510, the terminal device 1 confirms whether or not the user has pressed the channel selection button of the remote control function. When the user presses a channel selection button such as the “1” or “2” button displayed on the terminal device 1, the process proceeds to step S 1511, the corresponding channel selection command is transmitted to the video display device 3, and from step S 1503. Repeat the process.

If the user has not pressed the channel selection button displayed on the terminal device 1, in step S1512, the terminal device 1 checks whether the user has pressed any other button. Other setting changes include, for example, volume switching.

When the user instructs to change the setting of the video display device 3, the terminal device 1 transmits a setting command corresponding to the video display device 3 (step S1513), and repeats the processes from step S1503.

  FIG. 16 is a flowchart showing an oversight prevention process of the terminal device 1.

In step S1600, when the missed prevention mode of the terminal device 1 is on, the process proceeds to step S1601, and when it is off, the process ends.

In step S1601, the terminal device 1 waits for a certain period of time, for example, 5 minutes to elapse without the user changing the channel and without switching commercials, in step S1602.
The channel is stored in the storage unit 25. Here, commercial switching refers to switching from a television program to a commercial or from a commercial to a television program. In general, there is a silent part between a television program and a commercial. The television signal receiving unit 21 receives a television signal and detects a scene change when the voice is silent, thereby detecting the timing of switching commercials. be able to.

Next, in step S1603, the television signal reception unit 21 receives the television signal of the channel stored in the storage unit 25 and waits for the occurrence of commercial switching. When the user presses the channel selection button of the remote control function while waiting for the occurrence of commercial switching (step S1604), the terminal device 1 transmits a corresponding channel selection command to the video display device 3 (step S1605), The process from step S1601 is repeated.

In steps S1601 to S1605, commercial switching after a certain time has elapsed without the user changing the channel is detected, and commercial start timing is determined (step S1606).

Next, in step S1607, the television signal reception unit 21 receives the television signal of the channel stored in the storage unit 25 and waits for the occurrence of commercial switching. If the user presses the channel selection button of the remote control function while waiting for the occurrence of commercial switching (step S1608), the terminal device 1 transmits a corresponding channel selection command to the video display device 3 (step S1609).

Even when the channel of the video display device 3 is switched in step S1609, the process waits for the commercial switching of the channel stored in the storage unit 25 in step S1607.

In steps S1607 to S1609, the commercial switching after the commercial start is detected, and the commercial end timing is determined (step S1610).

Next, in step S1611, the channel selection command stored in the storage unit 25 is transmitted to the video display device 3, and the processes from step S1600 are repeated. Step S16
If the remote control function channel selection button is not pressed in 08, the channel selection command stored in the storage unit 25 may not be transmitted to the video display device 3.

  FIG. 17 is a flowchart showing the operation of the video display device 3.

In step S1701, the video display device 3 waits for reception of a power command. When the power command is received, the video display device 3 is turned on (step S1702).

Next, in step S1703, the video display device 3 confirms whether or not the power command has been received again. When the power command is received, the video display device 3 turns off the power (step S1704). If the power command has not been received, in step S1705, the video display device 3 checks whether a channel selection command has been received. When receiving the channel selection command, the video display device 3 executes the channel selection command as instructed (
Steps S1706) and S1703 are repeated.

If the channel selection command has not been received, in step S1707, the video display device 3 confirms whether another command has been received. If another command is received, the video display device 3 executes the command as instructed (step S1708) and repeats the processes from step S1703.

With the above configuration, in the seventh embodiment of the present invention, the terminal device 1 stores the channel when the user does not change the channel for a certain period of time, and sends the channel selection command in accordance with the commercial end timing. 3 to send.

Even if the user switches the channel during the commercial, the channel returns to the channel before the switching at the end of the commercial, so that the television program of the channel that the user was watching can be prevented from being overlooked.

Note that the channel when the video display device 3, not the terminal device 1, does not change the channel for a certain period of time may be stored, and the video display device 3 may detect the commercial end timing and switch to the channel.

Further, instead of the terminal device 1 or the video display device 3 switching the channel according to the commercial end timing, the user is notified of the commercial end by video or audio, and the user switches the channel by operating the terminal device 1 himself / herself. Good.

Next, an eighth embodiment of the present invention will be described. The configuration, effects, and the like in this example are the same as those in the seventh example unless otherwise specified. Therefore, the differences between the present embodiment and the seventh embodiment will be mainly described below, and the description of the common points will be omitted as much as possible in order to avoid duplication of explanation.

  FIG. 18 is a flowchart showing an oversight prevention process of the terminal device 1.

If the user presses the channel selection button of the remote control function while waiting for the occurrence of commercial switching (step S1804), the terminal device 1 transmits a corresponding channel selection command to the video display device 3 (step S1805), The steps from step S1801 are repeated.

In steps S1801 to S1805, a commercial switching after a predetermined time has elapsed without the user changing the channel is detected, and the commercial start or end timing is determined (step S1806).

In step S1807, the channel selection command stored in the storage unit 25 is transmitted to the video display device 3, and the processes from step S1800 are repeated.

With the above configuration, the eighth embodiment of the present invention can achieve the same effects as the seventh embodiment.

Further, since the channel when the user does not change the channel for a certain period of time is stored and the channel selection command is transmitted to the video display device 3 at the timing of the commercial start and end, there is no need to determine the commercial start and end. The miss-prevention process can be simplified.

Alternatively, the channel when the video display device 3 is not changed for a certain time instead of the terminal device 1 may be stored, and the video display device 3 may switch to the channel at the commercial start and end timings.

Also, instead of the terminal device 1 or the video display device 3 switching the channel at the commercial start and end timing, the user is notified of the commercial start and end by video or audio,
The user may switch the channel by operating the terminal device 1 himself / herself.

Next, a ninth embodiment of the present invention will be described. The configuration and effects in the present embodiment are the same as those in the seventh embodiment unless otherwise specified.

Since it is the same as that of step S1510, description is abbreviate | omitted. Steps S2707 to S2709
Thus, the commercial switching after the commercial start is detected, and the commercial end timing is determined (step S2710).

Next, in step S2711, the channel selection command stored in the storage unit 25 is transmitted to the video display device 3, and in step S2712, the missed prevention mode is turned off. If the channel selection button of the remote control function is not pressed in step S2708, the channel selection command stored in the storage unit 25 may not be transmitted to the video display device 3.

With the above configuration, in the fourteenth embodiment of the present invention, the terminal device 1 stores the channel that is being viewed when the user presses the “prevent overlook” mode button, and selects the channel according to the commercial end timing. The command is transmitted to the video display device 3.

If the user presses the “channel” button after pressing the “prevent overlook” mode button during a commercial, the channel that the user was watching will return to the previous channel when the commercial ends even if the user switches the channel during the commercial. Can be overlooked.

Further, by pressing the “prevent overlook” mode button during the commercial, the oversight prevention mode is set, and the mode is canceled when the commercial ends. Therefore, the power consumption of the terminal device 1 can be suppressed.

The video display device 3 may store the channel instead of the terminal device 1, and the video display device 3 may detect the commercial end timing and switch to the channel.

Further, instead of the terminal device 1 or the video display device 3 switching the channel according to the commercial end timing, the user is notified of the commercial end by video or audio, and the user switches the channel by operating the terminal device 1 himself / herself. Good.
