[First embodiment]

Please refer to FIG. 1, which is a block diagram of a system for starting a volume modulation widget according to a first embodiment of the present invention. As shown in FIG. 1, the volume modulation activation widget system of this embodiment includes a remote control 1, an electronic device 2, and a display device 3, wherein the electronic device 2 connects the remote control 1 to the display device 3, and the electronic device 2 serves as a display device The wireless signal receiver and controller of 3 are configured to receive and convert signals, commands or system applications from the remote control 1, and transmit the converted signals to instruct the display device 3 to perform display or audio output operations.

The remote control 1 may include one or more trigger keys, such as any one or any combination of a power key, a volume key, a screen brightness adjustment key, or other function keys. The number of trigger keys of the remote control 1 may depend on actual design requirements. For example, the remote control 1 may have multiple trigger keys to perform various functions, or may integrate multiple functions into a single trigger key. The trigger key may be a key, a sliding key such as a left sliding key, a right sliding key, etc., or other suitable types. It should be understood that the above is only an example, and not intended to limit the present invention, as long as the components and devices that trigger the volume change function of the display device 3 should cover the trigger keys (ie, hot keys) described herein.

In order to minimally affect the user's visual experience of watching the video played by the display device 3, that is, without affecting the smoothness of the video playback, such as not stopping the video playback, not reducing Under the conditions of slow or fast video playback speed and without adjusting the brightness of the screen, this embodiment temporarily does not use the power button as the trigger key, but uses the volume up and volume down keys as the configuration while the video is playing. The trigger key 100 for starting an external system such as a widget with a trigger. In practice, the trigger keys with different functions can be replaced to trigger and start an external system. For example, in order not to affect the user's auditory experience when watching a video, the screen brightness key can also be used as a trigger key, and the brightness of the display device 3 can be triggered by pressing the screen brightness key, such as dimming or brightening, and then triggering the activation of an external system. Or, for example, considering the different acceptance levels of different users, there may be multiple trigger keys with different functions at the same time, all of which can be used to trigger the startup widget. For example, the user can select from multiple levels according to the current acceptance of hearing and vision. Select one of the trigger keys to trigger the startup widget. The application of volume keys (including volume up and volume down keys) as the trigger key 100 shown in FIG. 1 will be described below, but those with ordinary knowledge in the technical field should understand how appropriate through the context description. The application of the volume key can be used as a trigger key for other functions.

The remote control 1 may further include a trigger key detection circuit 110. The trigger key detection circuit 110 can continuously detect the pressing state of the trigger key 100 of the remote controller 1. When the trigger key 100 such as the volume up key or the volume down key is pressed, the trigger key detection circuit 110 may output the trigger key status signal 111. For example, the trigger key detection circuit 110 may be a piezoelectric sensor, which is disposed inside the housing of the remote controller 1 adjacent to the bottom surface of the trigger key 100, so that the trigger key 100 is applied with pressure (eg, downward pressing force) When it is on the piezoelectric sensor, the piezoelectric sensor converts the pressure into the trigger key state signal 111 (electric signal) output.

The electronic device 2 may include a control circuit 200 connected to the trigger key detection circuit 110 of the remote controller 1. The control circuit 200 of the electronic device 2 may receive applications, signals, commands, databases, etc. applied to external systems such as widgets from an external electronic device in advance. For example, the electronic device 2 can be a set-top box, or other electronic component that also has the function of controlling the operation of the display device 3 according to the operation of the remote controller 1, and an operating system such as Android, Linux, Windows, etc. can be installed in the electronic device 2 , The above are only examples Note that the present invention is not limited to this.

Through the above configuration, when the electronic device 2 receives the trigger key status signal 111 from the remote control 1, the control circuit 200 can determine which trigger key 100 (volume up key or volume down key) is currently based on the trigger key status signal 111 Or it is pressed at a certain time, counts the number of presses of each trigger key 100 and the cumulative number of presses of all trigger keys 100, and determines the first adjustment volume according to the key state to output the corresponding first volume adjustment signal 201. For more precise control, the control circuit 200 can determine, according to the volume value represented by each volume of the volume display bar 311 of the display device 3 shown in FIG. The volume display bar 311 for adjusting the first volume of the signal 201, wherein each volume grid can be defined as the length of each segment of the volume display bar 311, is not limited to whether the volume display bar 311 is specifically divided into multiple grids.

The display device 3 includes an audio/video input/output circuit 300 connected to the control circuit 200 of the electronic device 2. The audio-visual input/output circuit 300 may be, for example, a speaker, which may be integrated with the display device 3 or separated from the display device 3 into an independent individual. The video input/output circuit 300 can output the original audio signal 309 matching the video while playing the video. When the audio/video input/output circuit 300 receives the first volume adjustment signal 201 from the electronic device 2, the original volume of the original audio source signal 309 is adjusted according to the first volume adjustment signal 201 to increase or decrease the first adjusted volume to output the first audio source signal 301 .

The display device 3 further includes a display screen 310 connected to the control circuit 200 of the electronic device 2. While the audio/video input/output circuit 300 outputs the first audio signal 301, the display device 3 can display a volume display bar 311 (as shown in FIG. 4) through the display screen 310. The length/volume of the volume bar marked in the volume display bar 311 The number depends on the original volume and the first adjusted volume. It should be understood that if the pressed trigger key 100 is a volume up key, the adjusted first volume is greater than the original volume, at this time the length/volume of the marked volume bar will be increased or decreased; on the contrary, if pressed The trigger key 100 is a volume down key, then the adjusted first volume is less than the original volume, at this time, the marked volume bar length/volume number will be reduced.

When the trigger key 100 of the remote controller 1 is pressed, or after the trigger key 100 is pressed and the display device 3 is triggered to increase or decrease the first adjusted volume, the control circuit 200 of the electronic device 2 may output a prompt signal 1232 to the display device 3 To instruct the display device 3 to display a prompt sentence 1233 (as shown in FIG. 4) corresponding to the prompt signal 1232 through the display screen 310. The prompt sentence 1233 may include information related to the widget activated by pressing the volume key 100 twice. It should be understood that the related work may also be omitted.

Further, when the trigger key 100 of the remote control 1 is pressed again according to the prompt of the prompt sentence 1233 of the display device 3 or before or without prompting, the control circuit 200 of the electronic device 2 will detect according to the trigger key from the remote control 1 The circuit 110 receives the trigger key status signal 111 representing the second press, determines the second adjusted volume and the second volume adjustment frame number/length corresponding to the second adjusted volume, and outputs the corresponding second volume adjustment signal 202.

The video input/output circuit 300 of the display device 3 adjusts the first volume of the first audio signal 301 according to the second volume adjustment signal 202 from the control circuit 200 of the electronic device 2 to increase or decrease the second adjusted volume to output the second audio signal 302 The second volume of the second audio signal 302 depends on the first volume and the second adjusted volume. While adjusting the volume, the display device 3 displays the volume display bar 311 through the display screen 310, and the length/volume number of the sound bar to increase or decrease the mark in the volume display bar 311 depends on the second adjusted volume.

It is worth noting that when the control circuit 200 determines that the video input/output circuit 300 of the display device 3 sequentially outputs the first audio signal 301 with the first adjusted volume and the second audio signal 302 with the second adjusted volume, in other words, the display When the device 3 has sequentially displayed the volume display bar 311 corresponding to the first adjusted volume and the second adjusted volume, respectively, the control circuit 200 activates an external system received from an external electronic device to control one or more external devices, and outputs an activation signal to The control display device 3 displays the operation interface of the external system through the display screen 310. The operation interface can be used to display or control the operation status of these external devices. The operation interface is located at a position where the image displayed on the screen 310 is not overlapped. For example, the external system may be, for example, FIG. 4 The widget 36 shown, various other applications or databases, etc. For example, the external system is a room control integrated system to control the operation of external devices such as the temperature of the indoor air conditioner and the operation of the electric fan. This application is for illustration only, not for This is limited.

As described above, in this embodiment, the trigger key 100 of the remote control 1 is pressed twice to trigger the display device 3 to generate two volume changes, and then trigger the operation of starting an external system such as a widget. In practice, it is possible to set more or fewer volume adjustments as a condition for starting an external system according to requirements. For example, there may be different pressing methods according to different users’ habits and volume adjustment amplitude requirements, such as short press once, Long press once, multiple short presses, or any combination of them, etc. The specific examples are as follows.

Please refer to FIGS. 2a to 2c, which are the first to third schematic diagrams of the pressing method of the remote control of the system of the volume modulation activation widget according to the first embodiment of the present invention.

As shown in FIG. 2a, a short press is used to trigger the control circuit 200 of the electronic device 2 to start the received/installed external system to control the external device. Specifically, the trigger key 100 of the remote control 1 is pressed for the first time at the time point Tp1 (as shown by the downward arrow in the figure), that is, the pressing time is short, for example, only 1 second or less, which is only exemplified here, Not limited to this.

In the time interval Inpv1 after the trigger key 100 is pressed at the time point Tp1, when the trigger key detection circuit 110 detects the pressed state of the trigger key, the trigger key state signal 111 is output to the audio-visual I/O circuit 300, and then the audio-visual I/O circuit 300 is based on Adjusting the original volume of the original audio signal 309 increases or decreases the first adjusted volume. Next, at the time point Tv1, the audio-visual input/output circuit 300 of the display device 3 outputs the first audio signal 301 having a first volume, which depends on the original volume and the first adjusted volume.

Then, after adjusting the volume of the display device 3 at the time point Tv1, within a preset time interval In122 after a waiting time interval In112, when the trigger key 100 of the remote controller 1 is pressed again, the display device 3 is triggered to generate the first Second, adjust the volume to trigger the start of the external system. In order to start the external system more quickly, the waiting time interval In112 can also be omitted. It should be understood that a short press is used for both times, so only The volume of the display device 3 is adjusted slightly.

As shown in FIG. 2b, using multiple short presses, the control circuit 200 of the electronic device 2 is triggered to start the received/installed external system to control the external device. At the time point Tp11, short press the trigger key 100 of the remote control 1 for the first time, and within the first preset time interval In11 after the first press, press the trigger key 100 three times, as shown in the number of downward arrows in FIG. 2b Represents a total of 4 short presses.

Then, in the time interval Inpv2, the control circuit 200 counts the number of presses of the trigger key 100 of the remote control 1 according to the plurality of trigger key status signals 111, and determines the size of the first adjustment volume of the display device 3 according to the number of presses and the length of time And output the corresponding first volume adjustment signal 201 to the audio/video input/output circuit 300. At the time point Tv11, the audio/video input/output circuit 300 of the display device 3 outputs the first audio source signal 301 in response to the first volume adjustment signal 201.

After the volume of the display device 3 is secondarily adjusted at the time point Tv11, the preset time interval In22 after a waiting time interval In12, that is, the time period from the time point T2 to the time point T22, is repeated multiple times (also When the trigger key 100 is short-pressed, the control circuit 200 can determine the size of the second adjustment volume of the display device 3 this time according to the number of presses and the length of time.

Compared to FIG. 2a, the pressing method used in FIG. 2b can adjust the volume of a larger amplitude when the external system is started at a time. In this embodiment, taking the number of pressings in the first preset time interval In11 and the number of pressings in the preset time interval In22 as an example, the practice may also be different. In order to avoid accidentally touching the trigger key 100 to activate the widget, more precise trigger activation conditions can be set, for example, the number of presses in the two preset time intervals In11, In22 reaches the preset number of times, or the two preset time intervals In11, The number of presses in In22 is the same, and the external system can start to control the external device. In this way, if the trigger key 100 of the remote control 1 has been pressed for the first time, but the user encounters an unexpected situation in the middle and regrets to cancel the activation of the external system and simply wants to adjust the volume, he can press the trigger key 100 under a non-preset condition.

As shown in FIG. 2c, a long press is used to trigger the control circuit of the electronic device 2 The road 200 initiates the operation of the external device received/installed by the external system. At the time point Tp111, the trigger key 100 of the remote control 1 is pressed for a period of time In111. Due to the longer pressing time, the first adjustment volume of the display device 3 is larger. In the time interval Inpv3 after the time point Tp112, the control circuit 200 counts the number of presses of the trigger key 100 of the remote controller 1 according to the trigger key status signal 111, and determines the second volume adjustment of the display device 3 according to the number of presses and the length of time Size, and output the corresponding second volume adjustment signal 202 to the video output circuit 300 of the display device 3. At the time point Tv111, the video input/output circuit 300 of the display device 3 outputs the second audio source signal 302 in response to the second volume adjustment signal 202.

When the display device 3 outputs the second audio signal 302, the control circuit 200 starts timing from the time point Tv111 at which the volume of the display device 3 is adjusted, and after the preset time interval In122, the trigger key 100 is pressed again. , Start the external system to control the external device.

The length of time in the above time intervals Inpv1, In112, In122, In11, Inpv2, In12, In22, In111, Inpv3, In122 can be set according to the actual operation. Implementation, in practice, the above examples can be arbitrarily combined and adjusted according to actual needs.

It is worth noting that in this embodiment, for example, when the trigger key 100 is pressed once, the display screen 310 of the display device 3 and the audio-visual input-output circuit 300 simultaneously display the volume display bar 311 and output the first audio signal 301 or the second audio signal 302, respectively. .

However, in practice, the operation of the display device 3 may alternatively be set such that when the trigger key 100 is pressed once, the display screen 310 of the display device 3 displays the volume display bar 311 for a period of time, and then when the trigger key 100 is pressed again within that period of time, At first, according to the first adjustment volume or the second adjustment volume, the volume output from the audio/video input/output circuit 300 and the corresponding volume bar length/volume number marked by the volume display bar 311 are adjusted. Those of ordinary skill in the art should be able to adjust the implementation of the embodiments herein appropriately according to the operation settings of the display device 3. For example, as shown in FIG. 2b, when the time point Tp11 is first pressed, the display device 3 displays on the display screen 310 The volume display bar 311 is displayed but the volume is not adjusted. The time interval In11 is the time period during which the volume display bar 311 is displayed. At other time points within the time interval In11 after the time point Tp11, the trigger key 100 (eg, 3 times) is pressed as the volume. Modulation trigger conditions.

In the above description, as long as the trigger key 100 of the remote control 1 is used twice (at least a predetermined time interval between two pressing time points) to trigger the display device 3 to generate volume modulation, the volume amplitude of the two modulations is the above Whether the first adjusted volume and the second adjusted volume are the same, whether the volume before the adjustment and the volume after the last adjustment are the same, can all start an external system operation. In the following, based on the adjusted volume of the display device 3 and the adjusted volume, it is determined whether to activate the external system to control the external device.

For example, when the control circuit 200 of the electronic device 2 compares the first adjusted volume and the second adjusted volume generated by the display device 3, the control circuit 200 activates the external system and controls the display device 3 to display the operation interface of the external system through The operation interface can only display or further control the operation status of the external device. Conversely, when the control circuit 200 compares the first adjusted volume with the second adjusted volume, the control circuit 200 does not start the external system and does not output the start signal.

For another example, when the control circuit 200 compares that the first adjusted volume and the second adjusted volume are different, the control circuit 200 activates an external system and controls the display device 3 to display an operation interface. Conversely, when the control circuit 200 compares the first adjusted volume with the second adjusted volume, it then compares whether the original volume of the original audio signal 309 and the second volume of the second audio signal 302 are the same. If the original volume and the second volume are different, the control circuit 200 starts the external system and controls the display device 3 to display the operation interface of the external system; conversely, if the original volume and the second volume are also the same, the control circuit 200 does not start the external system , And the start signal is not output. In other words, if the volume up key 100 is pressed for the first time to generate the first volume adjustment, and then the volume down key 100 is pressed again to generate the second volume adjustment same as the first volume adjustment, wherein the volume down key 100 and volume up key The 100 press sequence is also adjusted so that when the last adjusted volume, that is, the second volume is the same as the original volume, no external system-related operations are performed. Practice In the above, the comparison between the first adjusted volume and the second adjusted volume can also be omitted, and only the original volume and the second volume are directly compared.

It should be noted that different display devices 3 may have different volume adjustment ranges, such as 0 to 80 decibels. When the control circuit 200 of the electronic device 2 receives the trigger key status signal 111 from the trigger key detection circuit 110 of the remote controller 1, the control circuit 200 of the electronic device 2 can determine the original volume of the original audio signal 309 or the first audio signal 301 Whether the first volume of is the upper limit of the volume adjustment range.

If the original volume or the first volume is the upper limit of the volume adjustment range, for example, 80 decibels, then press the volume up key (trigger key 100), the control circuit 200 of the electronic device 2 will not output the first volume adjustment signal 201 or With the second volume adjustment signal 202, the display device 3 does not produce volume adjustment, that is, this pressing is not a condition for triggering the activation of an external system such as the widget 36. In this case, you need to press the volume down key (another trigger key 100) to adjust the volume and even start the external system.

Similarly, if the control circuit 200 of the electronic device 2 determines that the original volume or the first volume is the lower limit of the volume adjustment range, for example, 0 dB, then press the volume down key, the control circuit 200 of the electronic device 2 will not output the first volume A volume adjustment signal 201 or a second volume adjustment signal 202 does not trigger the display device 3 to generate volume adjustment. In this case, you need to press the volume up key to adjust the volume and even start the external system.
