In step S401, the terminal apparatus 1 waits until application software for performing the remote control of the video display apparatus 3 (hereinafter referred to as “operation application”) is started based on an operation by a user.
In step S402, the terminal apparatus 1 selects the video display apparatus 3 serving as a target of the remote control based on the operation by the user.
When the video display apparatus 3 serving as a target of the remote control is selected, the terminal apparatus 1 displays various types of instructions that can be transmitted to the video display apparatus 3.
Next, in step S403, the terminal apparatus 1 confirms whether the user has performed an operation for ending the operation application. When the operation for ending the operation application, for example, the operation of pressing an “end” button displayed on the terminal apparatus 1 has been performed, the terminal apparatus 1 returns to a process of displaying a menu screen.
In step S404, the terminal apparatus 1 confirms whether the user has pressed a “power” button. When the “power” button displayed on the terminal apparatus 1 has been pressed, the terminal apparatus 1 transmits a power supply command and an identification code to the video display apparatus 3 (step S405), and repeats the process from step S403.
When the “power” button displayed on the terminal apparatus 1 has not been pressed, in step S406, the terminal apparatus 1 confirms whether the user has pressed a channel setting button of a remote control function. When a channel setting button such as a “1” button or a “2” button displayed on the terminal apparatus 1 has been pressed, the process proceeds to step S407, and the corresponding channel is stored in the memory unit 25.
When the “1” button has been pressed, for example, “1” is stored in the memory unit 25. However, when “Ch+” has been then pressed, “2” is stored in the memory unit 25. When a setting command is specified by a relative value such as “Ch+” or “Ch−” like this, an absolute value such as “2” is substituted and stored.
Next, in step S408, the terminal apparatus 1 transmits a selection command and an identification code of the corresponding channel to the video display apparatus 3, and repeats the process from step S403.
When the channel setting button displayed on the terminal apparatus 1 has not been pressed, in step S409, the terminal apparatus 1 confirms whether the other button has been pressed. Examples of the other button include an audio volume setting button.
When the user has issued an instruction to change setting of the video display apparatus 3, the terminal apparatus 1 transmits a corresponding setting command and identification code to the video display apparatus 3 (step S410), and repeats the process from step S403.
When the other button displayed on the terminal apparatus 1 has not been pressed, in step S411, the terminal apparatus 1 confirms whether a channel switching notification has been received as status information.
When the channel switching notification has been received, the terminal apparatus 1 sets the channel stored in the memory unit 25 to the television signal receiving unit 31, and displays a received video on the display unit 22 and outputs an audio from the audio output unit 23 (step S412), and repeats the process from step S403.
The channel switching notification is transmitted from the video display apparatus 3. For example, when channel switching by the terminal apparatus 1b other than the terminal apparatus 1a, which has powered on the video display apparatus 3, has occurred, the video display apparatus 3 transmits the channel switching notification as status information to the terminal apparatus 1a.
When the terminal apparatus 1 has not received the channel switching notification, the terminal apparatus 1 repeats the process from step S403.
In step S601, the video display apparatus 3 waits for receiving of a power supply command. When the power supply command has been received, the process proceeds to step S602, and the video display apparatus 3 is powered on. Then, in step S603, an identification code when the power supply command has been received is stored in the memory unit 35. Here, it is assumed that an identification code of the terminal apparatus 1a has been received.
Next, in step S604, the video display apparatus 3 confirms whether the power supply command has been received again. When the power supply command has been received, the process proceeds to step S605, and the video display apparatus 3 is powered off, and the process ends.
While toggle control to repeat power on/off every time the video display apparatus 3 receives the power supply command is illustrated as an example in the present embodiment, a power-on command and a power-off command may be separated from each other.
When the video display apparatus 3 has not received the power supply command in step S604, the process proceeds to step S606, and the video display apparatus 3 confirms whether a channel setting command has been received. When the channel setting command has been received, the process proceeds to step S607, and the command is executed as instructed.
Next, in step S608, the video display apparatus 3 confirms whether an identification code when the channel setting command has been received matches the identification code stored in the memory unit 35. When the identification codes match each other, the process from step S604 is repeated.
When the identification codes do not match each other, the video display apparatus 3 transmits a channel switching notification as status information to the terminal apparatus 1a corresponding to the identification code stored in the memory unit 35 (step S609), and repeats the process from step S604.
Also, when the video display apparatus 3 has not received the channel setting command in step S606, the process proceeds to step S610, and the video display apparatus 3 confirms whether the other command has been received. When the other command has been received, the video display apparatus 3 executes the command as instructed (step S611), and repeats the process from step S604. Examples of the other command include an audio volume setting command.
When the other command has not been received, the process from step S604 is repeated.
When the terminal apparatus 1a powers on the video display apparatus 3 by remote control in the above-described manner, the video display apparatus 3 is powered on.
Next, when the terminal apparatus 1a performs channel switching of the video display apparatus 3 by remote control, the channel of the video display apparatus 3 is switched as instructed. When another terminal apparatus 1b performs channel switching of the video display apparatus 3 by remote control, the channel of the video display apparatus 3 is switched as instructed, and a channel switching notification is transmitted as status information to the terminal apparatus 1a.
When the terminal apparatus 1a has received the channel switching notification, the terminal apparatus 1a displays the video of the channel prior to the switching by the terminal apparatus 1b on the display unit 22, and outputs the audio thereof from the audio output unit 23.
Note that it is also possible to ask the user whether the start of the display of the video and the output of the audio is permitted before the display of the video and the output of the audio are started.
By the foregoing configuration, in the first embodiment of the present invention, when the channel of the video display apparatus set by the remote control from a terminal apparatus is switched by another terminal apparatus, a content displayed on the video display apparatus prior to the switching is displayed on the terminal apparatus. Even if a channel set by a user is switched by another user, the user can view the channel by using the terminal apparatus at hand without any particular operation. Thus, it is possible to prevent the content from being missed.
Since steps S701 to S707 are similar to steps S601 to S607 illustrated in
In step S708, the video display apparatus 3 confirms whether an identification code when a channel setting command has been received matches an identification code stored in the memory unit 35.

When the terminal apparatus 1a receives the channel switching notification, the terminal apparatus 1a displays the video of the channel prior to the switching by the terminal apparatus 1b on the display unit 22, and outputs an audio thereof from the audio output unit 23.
When a terminal apparatus 1c further switches the channel of the video display apparatus 3 by remote control, the channel of the video display apparatus 3 is switched as instructed, and a channel switching notification is transmitted as status information to the terminal apparatus 1b.
When the terminal apparatus 1b receives the channel switching notification, the terminal apparatus 1b displays the video of the channel prior to the switching by the terminal apparatus 1c on the display unit 22, and outputs an audio thereof from the audio output unit 23.
By the foregoing configuration, in the second embodiment of the present invention, a similar effect to that in the first embodiment can be obtained.
Thus, when the channel of the video display apparatus set by the remote control from a terminal apparatus is switched by another terminal apparatus and the channel is further switched by still another terminal apparatus, a content displayed on the video display apparatus prior to the switching is displayed on each of the terminal apparatuses. Even if a channel set by a user is switched by another user, the user can view the channel by using the terminal apparatus at hand without any particular operation. Thus, it is possible to prevent the content from being missed.

Even if a channel set by a user is switched by another user, the content is recorded and reproduced by the video display apparatus without any particular operation by the user. Thus, it is possible to prevent the content from being missed.
In step S1501, the terminal apparatus 1 waits until application software for performing the remote control of the video display apparatus 3 (hereinafter referred to as “operation application”) is started based on an operation by the user.
In step S1502, the terminal apparatus 1 selects the video display apparatus 3 serving as a target of the remote control based on the operation by the user.
When the video display apparatus 3 serving as a target of the remote control is selected, the terminal apparatus 1 displays various types of instructions that can be transmitted to the video display apparatus 3.
Next, in step S1503, the terminal apparatus 1 confirms whether the user has performed an operation for ending the operation application. When the user has performed the operation for ending the operation application, for example, the operation of pressing an “end” button displayed on the terminal apparatus 1, the terminal apparatus 1 returns to a process for displaying a menu screen.
In step S1504, the terminal apparatus 1 confirms whether the user has pressed a “power” button. When the user has pressed the “power” button displayed on the terminal apparatus 1, the terminal apparatus 1 transmits a power supply command to the video display apparatus 3 (step S1505), and repeats the process from step S1503.
When the user has not pressed the “power” button displayed on the terminal apparatus 1, the terminal apparatus 1 confirms whether the user has pressed a “missing prevention” mode button in step S1506. When the user has pressed the “missing prevention” mode button displayed on the terminal apparatus 1, the terminal apparatus 1 switches ON and OFF of a missing prevention mode (step S1507). When the missing prevention mode is ON, the terminal apparatus 1 turns off the missing prevention mode in step S1508, and when the missing prevention mode is OFF, the terminal apparatus 1 turns on the missing prevention mode in step S1509. Then, the process from step S1503 is repeated.
The missing prevention mode is for preventing a television program on an original channel from being missed after the end of a video of advertisement means accompanying the television program such as CM (Commercial Message, hereinafter referred to as “commercial”) or announcement means such as an announcement of a program. More specifically, even if the user switches the channel after the start of the video of the advertisement means or the announcement means, the channel is switched to the original channel at the timing of the end of the video. Thus, for example, even if the user is viewing a television program on a channel A and switches the channel A to a channel B or a channel C after the television program is switched to a commercial, the display on the video display apparatus 3 is switched to the channel A at the timing at which the commercial on the channel A ends and is switched to the television program.
When the user has not pressed the “missing prevention” mode button displayed on the terminal apparatus 1, the terminal apparatus 1 confirms whether the user has pressed a channel selection button of a remote control function in step S1510. When the user has pressed a channel selection button such as a “1” button or a “2” button displayed on the terminal apparatus 1, the process proceeds to step S1511, and a selection command of a corresponding channel is transmitted to the video display apparatus 3 and the process from step S1503 is repeated.
When the user has not pressed the channel selection button displayed on the terminal apparatus 1, the terminal apparatus 1 confirms whether the user has pressed the other button in step S1512. Examples of other setting changes include switching of an audio volume.
When the user has issued an instruction to change setting of the video display apparatus 3, the terminal apparatus 1 transmits a corresponding setting command to the video display apparatus 3 (step S1513), and the process from step S1503 is repeated.
When the missing prevention mode of the terminal apparatus 1 is ON in step S1600, the process proceeds to step S1601, and when the missing prevention mode is OFF, the process ends.
In step S1601, the terminal apparatus 1 waits for an elapse of a predetermined period of time, e.g., five minutes during which the user does not change a channel and there is no commercial switching, and the terminal apparatus 1 stores the channel in the memory unit 25 in step S1602. The commercial switching mentioned here means switching from a television program to a commercial and switching from a commercial to a television program. Generally, there is a point in which an audio is silent between a television program and a commercial, and the timing at which the commercial switching occurs can be detected when a television signal is received by a television signal receiving unit 21 and a scene change where an audio is silent is detected.
Next, in step S1603, the terminal apparatus 1 receives a television signal of the channel stored in the memory unit 25 by using the television signal receiving unit 21, and waits for the occurrence of the commercial switching. When the user has pressed a channel selection button of a remote control function while waiting for the occurrence of the commercial switching (step S1604), the terminal apparatus 1 transmits a selection command of a corresponding channel to the video display apparatus 3 (step S1605), and repeats the process from step S1601.
Through steps S1601 to S1605, the terminal apparatus 1 detects the commercial switching after an elapse of a predetermined period of time without the channel change by the user, and determines that a commercial start timing has come (step S1606).
Next, in step S1607, the terminal apparatus 1 receives the television signal of the channel stored in the memory unit 25 by the television signal receiving unit 21, and waits for the occurrence of the commercial switching. When the user has pressed the channel selection button of a remote control function while waiting for the occurrence of the commercial switching (step S1608), the terminal apparatus 1 transmits a selection command of a corresponding channel to the video display apparatus 3 (step S1609).
Also when the channel of the video display apparatus 3 is switched in step S1609, the terminal apparatus 1 waits for the occurrence of the commercial switching of the channel stored in the memory unit 25 in step S1607.
Through steps S1607 to S1609, the terminal apparatus 1 detects the commercial switching after the start of the commercial, and determines that a commercial end timing has come (step S1610).
Next, in step S1611, the terminal apparatus 1 transmits the selection command of the channel stored in the memory unit 25 to the video display apparatus 3, and repeats the process from step S1600. When the channel selection button of a remote control function has not been pressed in step S1608, the terminal apparatus 1 does not have to transmit the selection command of the channel stored in the memory unit 25 to the video display apparatus 3.
In step S1701, the video display apparatus 3 waits for receiving of a power supply command. When the power supply command has been received, the video display apparatus 3 is powered on (step S1702).
Next, in step S1703, it is confirmed whether the video display apparatus 3 has received the power supply command again. When the power supply command has been received, the video display apparatus 3 is powered off (step S1704). When the power supply command has not been received, the video display apparatus 3 confirms whether a channel selection command has been received in step S1705. When the channel selection command has been received, the video display apparatus 3 executes the channel selection command as instructed (step S1706), and repeats the process from step S1703.
When the channel selection command has not been received, the video display apparatus 3 confirms whether another command has been received in step S1707. When the other command has been received, the video display apparatus 3 executes the command as instructed (step S1708), and repeats the process from step S1703.
By the foregoing configuration, in the seventh embodiment of the present invention, the terminal apparatus 1 stores the channel when the user does not change a channel for a predetermined period of time, and transmits a selection command of the channel to the video display apparatus 3 in response to a commercial end timing.
Even if the user switches a channel during a commercial, the channel returns to the channel prior to the switching when the commercial ends. Thus, it is possible to prevent a television program on the channel, which has been being viewed by the user, from being missed.
Instead of the terminal apparatus 1, the video display apparatus 3 may store the channel when the channel is not changed for a predetermined period of time, and the video display apparatus 3 itself may detect a commercial end timing and switch the channel to a corresponding channel.
Alternatively, instead of the configuration in which the terminal apparatus 1 or the video display apparatus 3 switches the channel in response to the commercial end timing, the user may be notified of the end of the commercial by a video or an audio, and the user himself/herself may operate the terminal apparatus 1 to switch the channel.
Next, the eighth embodiment of the present invention will be described below. A configuration, an effect, and the like in the present embodiment are similar to those in the seventh embodiment unless otherwise noted. Thus, a difference between the present embodiment and the seventh embodiment will be mainly described below, and description of common points is omitted as much as possible in order to avoid an overlap of the description.
When a missing prevention mode of the terminal apparatus 1 is ON in step S1800, the process proceeds to step S1801, and when the missing prevention mode is OFF, the process ends.
When a user has not changed a channel for a predetermined period of time, e.g., five minutes in step S1801, the terminal apparatus 1 stores the channel in the memory unit 25 in step S1802. Next, in step S1803, the terminal apparatus 1 receives a television signal of the channel stored in the memory unit 25 by a television signal receiving unit 21, and waits for the occurrence of commercial switching. When the user has pressed a channel selection button of a remote control function while the terminal apparatus 1 waits for the occurrence of the commercial switching (step S1804), the terminal apparatus 1 transmits a selection command of a corresponding channel to the video display apparatus 3 (step S1805), and repeats the process from step S1801.
Through steps S1801 to S1805, the terminal apparatus 1 detects the commercial switching after an elapse of a predetermined period of time without the channel change by the user, and determines that a commercial start or end timing has come (step S1806).
Next, in step S1807, the terminal apparatus 1 transmits the selection command of the channel stored in the memory unit 25 to the video display apparatus 3, and repeats the process from step S1800.
By the foregoing configuration, in the eighth embodiment of the present invention, a similar effect to that in the seventh embodiment can be obtained.
Furthermore, since the terminal apparatus 1 stores the channel when the user does not change the channel for a predetermined period of time, and transmits a selection command of the channel to the video display apparatus 3 at the timing of start and end of the commercial, it is not necessary to distinguish the start and the end of the commercial, and the missing prevention process can be simplified.
Instead of the terminal apparatus 1, the video display apparatus 3 may store the channel when the channel is not changed for a predetermined period of time, and the video display apparatus 3 itself may switch the channel to the corresponding channel at the timing of start or end of the commercial.
Alternatively, instead of the configuration in which the terminal apparatus 1 or the video display apparatus 3 switches the channel at the timing of start or end of the commercial, the user may be notified of the start or end of the commercial by a video or an audio, and the user himself/herself may operate the terminal apparatus 1 to switch the channel.
Next, the ninth embodiment of the present invention will be described below. A configuration, an effect, and the like in the present embodiment are also similar to those in the seventh embodiment unless otherwise noted. Thus, a difference between the present embodiment and the seventh embodiment will be mainly described below.
When a missing prevention mode of the terminal apparatus 1 is ON in step S1900, the process proceeds to step S1901, and when the missing prevention mode is OFF, the process ends.
Since steps S1901 to S1905 are similar to steps S1601 to S1605 illustrated in
Next, in step S1907, the terminal apparatus 1 receives a television signal of the channel stored in the memory unit 25 by a television signal receiving unit 21, and waits for the occurrence of the commercial switching. When the user has pressed a channel selection button of a remote control function while the terminal apparatus 1 waits for the occurrence of the commercial switching (step S1908), the terminal apparatus 1 transmits a two-screen display start command to the video display apparatus 3 (step S1909), and transmits a selection command of a corresponding channel for an added screen to the video display apparatus 3 (step S1910). When the user has pressed the channel selection button of a remote control function again while the terminal apparatus 1 waits for the occurrence of the commercial switching, the terminal apparatus 1 does not have to transmit the two-screen display start command in step S1909.
Also when a channel of the video display apparatus 3 has been switched in step S1909, the terminal apparatus 1 waits for the occurrence of the commercial switching of the channel stored in the memory unit 25 in step S1907.
Through steps S1907 to S1910, the terminal apparatus 1 detects the commercial switching after the start of the commercial, and determines that a commercial end timing has come (step S1911).
Next, in step S1912, the terminal apparatus 1 transmits a two-screen display end command to the video display apparatus 3, and repeats the process from step S1900. The screen added later is erased when the two-screen display ends. The two-screen display end command does not have to be transmitted when the screen has not been switched to the two-screen display.
By the foregoing configuration, in the ninth embodiment of the present invention, a similar effect to that in the seventh embodiment can be obtained.
Furthermore, the terminal apparatus 1 stores the channel when the user does not change a channel for a predetermined period of time, and when the channel selection button is pressed during the commercial, the terminal apparatus 1 switches the video display apparatus 3 to the two-screen display and displays the channel on the added screen. Then, the terminal apparatus 1 ends the two-screen display in response to the timing of the end of the commercial.
Since the video on the original channel can be confirmed by the two-screen display even when the channel is switched, the user can switch the channel without worrying about missing a television program.
Instead of the terminal apparatus 1, the video display apparatus 3 may store the channel when the channel is not changed for a predetermined period of time, and the video display apparatus 3 itself may start and end the two-screen display.
Also, since the user can confirm both of the video on the original channel and the video on the channel after the switching by the two-screen display, the user himself/herself may operate the terminal apparatus 1 to end the two-screen display instead of the configuration in which the terminal apparatus 1 ends the two-screen display in response to the timing of the end of the commercial.
Next, the tenth embodiment of the present invention will be described below. A configuration, an effect, and the like in the present embodiment are similar to those in the seventh embodiment unless otherwise noted. Thus, a difference between the present embodiment and the seventh embodiment will be mainly described below.
When a missing prevention mode of the terminal apparatus 1 is ON in step S2000, the process proceeds to step S2001, and when the missing prevention mode is OFF, the process ends.
Since steps S2001 to S2005 are similar to steps S1601 to S1605 illustrated in
Next, in step S2007, the terminal apparatus 1 receives a television signal of the channel stored in the memory unit 25 by a television signal receiving unit 21, and waits for the occurrence of the commercial switching. When the user has pressed a channel selection button of a remote control function while the terminal apparatus 1 waits for the occurrence of the commercial switching (step S2008), the terminal apparatus 1 transmits a selection command of a corresponding channel to the video display apparatus 3 (step S2009), and displays a video on the channel stored in the memory unit 25 in the terminal apparatus 1 on the display unit 22 (step S2010).
Also when a channel of the video display apparatus 3 has been switched in step S2009, the terminal apparatus 1 waits for the occurrence of the commercial switching of the channel stored in the memory unit 25 in step S2007.
Through steps S2007 to S2010, the terminal apparatus 1 detects the commercial switching after determining the commercial start timing, and determines that a commercial end timing has come (step S2011).
Next, in step S2012, the terminal apparatus 1 transmits a selection command of the channel stored in the memory unit 25 to the video display apparatus 3, and repeats the process from step S2000.
By the foregoing configuration, in the tenth embodiment of the present invention, a similar effect to that in the seventh embodiment can be obtained.
Furthermore, the terminal apparatus 1 stores the channel when the user does not change a channel for a predetermined period of time, switches the channel of the video display apparatus 3 when a channel selection button is pressed during a commercial, and displays a video on the original channel on the screen of the terminal apparatus 1. Then, the terminal apparatus 1 returns the channel of the video display apparatus 3 to the original channel in response to the commercial end timing.
Since the video on the original channel can be confirmed by the terminal apparatus 1 even when the channel has been switched, the user can switch the channel without worrying about missing a television program.
The video display apparatus 3 as well as the terminal apparatus 1 may also store the channel when the channel is not changed for a predetermined period of time, and the video display apparatus 3 itself may detect the commercial end timing to switch the channel to a corresponding channel.
Also, since the user can confirm the video on the original channel by the terminal apparatus 1, the user himself/herself may operate the terminal apparatus 1 to end the two-screen display instead of the configuration in which the terminal apparatus 1 ends the two-screen display in response to the commercial end timing.
Next, the eleventh embodiment of the present invention will be described below. A configuration, an effect, and the like in the present embodiment are similar to those in the seventh embodiment unless otherwise noted. Thus, a difference between the present embodiment and the seventh embodiment will be mainly described below.
When a missing prevention mode of the terminal apparatus 1 is ON in step S2100, the process proceeds to step S2101, and when the missing prevention mode is OFF, the process ends.
Since steps S2101 to S2105 are similar to steps S1601 to S1605 illustrated in
Since steps S2107 to S2109 are similar to steps S1607 to S1609 illustrated in
Through steps S2107 to S2109, the terminal apparatus 1 detects the commercial switching after the start of the commercial, and determines that a commercial end timing has come (step S2110).
Next, in step S2112, the process is changed depending on whether a program on an original channel has ended. When the program has not ended, the process proceeds to step S2111, and the terminal apparatus 1 transmits a selection command of the channel stored in the memory unit 25 to the video display apparatus 3 and repeats the process from step S2100. When the program has ended, the process does not proceed to step S2111, and the process from step S2100 is repeated.
By the foregoing configuration, in the eleventh embodiment of the present invention, a similar effect to that in the seventh embodiment can be obtained.
Furthermore, since the terminal apparatus 1 does not return the channel to the original channel when the program has ended, the terminal apparatus 1 does not erroneously switch the channel which the user wishes to view next.
Instead of the terminal apparatus 1, the video display apparatus 3 may store the channel when the channel is not changed for a predetermined period of time, and the video display apparatus 3 itself may detect the commercial end timing and switch the channel to a corresponding channel.
Next, the twelfth embodiment of the present invention will be described below. A configuration, an effect, and the like in the present embodiment are similar to those in the seventh embodiment unless otherwise noted. Thus, a difference between the present embodiment and the seventh embodiment will be mainly described below.
When a missing prevention mode of the terminal apparatus 1 is ON in step S2200, the process proceeds to step S2201, and when the missing prevention mode is OFF, the process ends.
Since steps S2201 to S2202 are similar to steps S1601 to S1602 illustrated in
Next, in step S2212, the process is changed depending on whether the channel has a commercial. When the channel has a commercial, the process proceeds to step S2203, and when the channel has no commercial, the process does not proceed to step S2203 and the process from step S2200 is repeated. For example, whether or not the channel has a commercial can be determined by storing a list of channels having no commercial in the memory unit 25 in advance and comparing the list of channels with the channel stored in step S2202.
Since steps S2203 to S2205 are similar to steps S1603 to S1605 illustrated in
Through steps S2201 to S2205 and step S2212, the terminal apparatus 1 detects the commercial switching in the channel having a commercial after an elapse of a predetermined period of time without the channel change by the user, and determines that a commercial start timing has come (step S2206).
Since steps S2201 to S2205 are similar to steps S1601 to S1605 illustrated in
Since steps S2207 to S2209 are similar to steps S1607 to S1609 illustrated in
Through steps S2207 to S2209, the terminal apparatus 1 detects the commercial switching after the start of a commercial, and determines that a commercial end timing has come (step S2210).
Next, in step S2211, the terminal apparatus 1 transmits a selection command of the channel stored in the memory unit 25 to the video display apparatus 3, and repeats the process from step S2200.
By the foregoing configuration, in the twelfth embodiment of the present invention, a similar effect to that in the seventh embodiment can be obtained.
Furthermore, since the terminal apparatus 1 does not perform the missing prevention process for the channel having no commercial, the missing prevention process is not erroneously performed when the channel is switched to the channel having no commercial. Since there is a scene change where an audio is silent even on the channel having no commercial, there is the possibility that the terminal apparatus 1 determines that the commercial switching has occurred, but it is possible to prevent this.
Instead of the terminal apparatus 1, the video display apparatus 3 may store the channel when the channel is not changed for a predetermined period of time, and the video display apparatus 3 itself may detect the commercial end timing and switch the channel to a corresponding channel.
Also, instead of the configuration in which the terminal apparatus 1 or the video display apparatus 3 switches the channel in response to the commercial end timing, the user may be notified of the end of the commercial by a video or an audio, and the user himself/herself may operate the terminal apparatus 1 to switch the channel.
Next, the thirteenth embodiment of the present invention will be described below. A configuration, an effect, and the like in the present embodiment are similar to those in the seventh embodiment unless otherwise noted. Thus, a difference between the present embodiment and the seventh embodiment will be mainly described below.
Since steps S2401 to S2409 are similar to steps S1501 to S1509 illustrated in
In step S2410, the terminal apparatus 1 confirms whether a user has pressed a channel selection button of a remote control function. When the user has pressed a channel selection button such as a “1” button or a “2” button displayed on the terminal apparatus 1, the process proceeds to step S2411. Since step S2411 is similar to step S1511 illustrated in
Next, in step S2414, the process is changed depending on whether the terminal apparatus 1 has received a status indicating that there is no channel selection authority. Only when the status has been received, the process proceeds to step S2415, and a video on a corresponding channel is displayed on the display unit 22 in the terminal apparatus 1. Then, the process from step S2403 is repeated. The status indicating that there is no channel selection authority is sent from the video display apparatus 3 when there is no channel selection authority.
When the user has not pressed the channel selection button of a remote control function displayed on the terminal apparatus 1 in step S2410, the process proceeds to step S2412. Since steps S2412 to S2413 are similar to steps S1512 to S1513 illustrated in
Thus, when there is no channel selection authority of the video display apparatus 3, the video on the corresponding channel is displayed on the terminal apparatus 1.
In step S2501, the video display apparatus 3 waits for receiving of a power supply command. When the power supply command has been received, the video display apparatus 3 is powered on (step S2502), and stores, in the memory unit 35, information indicating which of terminal apparatuses 1 has transmitted the power supply command, namely, an identification code which has been transmitted together with the power supply command (step S2509). Here, it is assumed that the terminal apparatus 1a has transmitted the power supply command.
An IP (Internet Protocol) address, an ID (Identification) individually assigned to the terminal apparatus 1, a telephone number and the like are applicable to the identification code. Generally, since it is assumed that one user possesses one terminal apparatus 1, a user ID given to each user by a manufacturer of the terminal apparatus 1 may be applied. In this case, the user ID is previously stored in the terminal apparatus 1 based on an operation by the user or the like.
Since steps S2503 to S2504 are similar to steps S1703 to S1704 illustrated in
Next, in step S2505, the video display apparatus 3 confirms whether a channel selection command has been received. When the channel selection command has been received, the video display apparatus 3 confirms whether the channel selection command is a setting command from a specific terminal apparatus 1, namely, the terminal apparatus 1 that has issued an instruction to turn on power (step S2510). When the channel selection command is the setting command from the terminal apparatus 1 that has issued the instruction to turn on power, the video display apparatus 3 executes the channel selection command as instructed (step S2506), and repeats the process from step S2503.
When the channel selection command is not the setting command from the terminal apparatus 1 that has issued the instruction to turn on power in step S2510, the video display apparatus 3 confirms whether a channel being displayed is during a commercial (step S2511). When the channel is during the commercial, the video display apparatus 3 executes the command as instructed (step S2506), and repeats the process from step S2503. When the channel is not during the commercial, the video display apparatus 3 sends status information indicating that there is no channel selection authority to the corresponding terminal apparatus 1 (step S2512), and then repeats the process from step S2503. Whether the channel is during the commercial may be transmitted from the terminal apparatus 1 in addition to being determined by the video display apparatus 3.
Since steps S2507 to S2508 are similar to steps S1707 to S1708 illustrated in
Thus, selection of the channel of the video display apparatus 3 can be performed only when it is instructed from the terminal apparatus 1a that has powered on the video display apparatus 3 during a television program, and can be performed also when it is instructed from the terminal apparatus 1b in addition to the terminal apparatus 1a during a commercial. Also, an operation other than the selection of the channel can be performed from both of the terminal apparatus 1a and the terminal apparatus 1b.
By the foregoing configuration, in the thirteenth embodiment of the present invention, a similar effect to that in the seventh embodiment can be obtained.
Furthermore, the selection of the channel of the video display apparatus 3 can be performed only when it is instructed from the terminal apparatus 1a that has powered on the video display apparatus 3 during a television program, and a video is displayed on the terminal apparatus 1b when it is instructed from the terminal apparatus 1b. In addition, during the commercial, the channel selection can be performed also when it is instructed from the terminal apparatus 1b in addition to the terminal apparatus 1a.
Since steps S2601 to S2605 are similar to steps S1501 to S1505 illustrated in
In step S2606, the terminal apparatus 1 confirms whether a user has pressed a “missing prevention” mode button. When the user has pressed the “missing prevention” mode button displayed on the terminal apparatus 1, the terminal apparatus 1 turns on a missing prevention mode, and repeats the process from step S2603.
When the user has not pressed the “missing prevention” mode button displayed on the terminal apparatus 1, the process proceeds to step S2610. Since steps S2610 to S2613 are similar to steps S1510 to S1513 illustrated in
When the missing prevention mode of the terminal apparatus 1 is ON in step S2700, the process proceeds to step S2701, and when the missing prevention mode is OFF, the process ends.
In step S2701, the terminal apparatus 1 stores a channel previously set by the user.
Since steps S2707 to S2710 are similar to steps S1507 to S1510 illustrated in
Next, in step S2711, the terminal apparatus 1 transmits a selection command of the channel stored in the memory unit 25 to the video display apparatus 3, and turns off the missing prevention mode in step S2712. When the channel selection button of a remote control function has not been pressed in step S2708, the selection command of the channel stored in the memory unit 25 does not have to be transmitted to the video display apparatus 3.
By the foregoing configuration, in the fourteenth embodiment of the present invention, the terminal apparatus 1 stores the channel which is being viewed when the user has pressed the “missing prevention” mode button, and transmits the selection command of the channel to the video display apparatus 3 in response to the timing of the end of the commercial.
If the user has pressed the “channel” button after pressing the “missing prevention” mode button during the commercial, the channel returns to the channel prior to the switching at the end of the commercial even when the user switches the channel during the commercial. Thus, it is possible to prevent the television program on the channel which has been being viewed by the user from being missed.
Furthermore, when the “missing prevention” mode button is pressed during the commercial, a missing prevention mode is entered, and the missing prevention mode is canceled when the commercial ends. Therefore, the power consumption of the terminal apparatus 1 can be suppressed.
Instead of the terminal apparatus 1, the video display apparatus 3 may store the channel, and the video display apparatus 3 itself may detect the commercial end timing and switch the channel.
Also, instead of the configuration in which the terminal apparatus 1 or the video display apparatus 3 switches the channel in response to the commercial end timing, the user may be notified of the end of the commercial by a video or an audio, and the user himself/herself may operate the terminal apparatus 1 to switch the channel.
Note that the embodiments above have been described in detail so as to make the present invention easily understood, and the present invention is not limited to the embodiment having all of the described constituent elements. Also, a part of the configuration of one embodiment may be replaced with the configuration of another embodiment, and the configuration of one embodiment may be added to the configuration of another embodiment. Furthermore, another configuration may be added to a part of the configuration of each embodiment, and a part of the configuration of each embodiment may be eliminated or replaced with another configuration.
Some or all of the above-mentioned configurations, functions, processing units, and processing means may be implemented by hardware by designing them with integrated circuits or the like. Also, the above-mentioned configurations and functions may be implemented by software by interpreting and executing programs for implementing the respective functions by processors. Information such as a program, a table, a file, and the like for implementing each of the functions can be placed in a recording device such as a memory, a hard disk, or an SSD (Solid State Drive) or a recording medium such as an IC card or an SD card.
Control lines and information lines, which are considered to be necessary in description, are illustrated, and all control lines and information lines in products are not necessarily illustrated. In practice, it is right to think that almost all configurations are connected to one another.
