The audio state of thepower amplifier device 500 may specifically include a mute state and a non-mute state, where the mute state indicates that the audio volume output by thepower amplifier device 500 is zero; the non-mute state indicates that the audio output from thepower amplifier 500 has a certain volume. The audio state of thepower amplifier device 500 can be controlled or changed by the user.
When thedisplay device 200 and the externalpower amplifier device 500 are connected through an ARC (Audio Return Channel) or the connection is successful, the user may manually adjust the volume of the externalpower amplifier device 500 or mute the externalpower amplifier device 500 using a remote controller. Under normal conditions, the externalpower amplifier device 500 may actively report the current audio state of thepower amplifier device 500 to thedisplay device 200 by sending a CEC (Consumer Electronics Control) command, for example, a volume value or a mute state. Thedisplay device 200 displays the audio status, thereby informing the user of the audio status of the currently accessed externalpower amplifier device 500.
However, at present, part of thepower amplifier devices 500 do not actively report the audio status to thedisplay device 200 through the CEC command due to their own configuration. This situation may affect the user's understanding of the audio state of thepower amplifier device 500, and may not adjust the audio state of thepower amplifier device 500 more accurately. Thereby affecting the user's experience using thedisplay device 200 and thepower amplifying device 500.
In order to solve the problem that part of thepower amplifier devices 500 cannot actively report the audio state to thedisplay device 200, the embodiments of the present application provide adisplay device 200 and apower amplifier device 500.
Fig. 5 shows a schematic diagram of interaction between thedisplay device 200 and thepower amplifier device 500 according to some embodiments. Thepower amplifier device 500 may be connected to thedisplay device 200 through the ARC of thedisplay device 200 and output audio contents on thedisplay device 200. As shown in fig. 5, after thedisplay device 200 is connected to thepower amplifier device 500, thedisplay device 200 may be connected to acontrol device 100 such as a remote controller, so that the user may control thedisplay device 200 and further control thepower amplifier device 500 through thecontrol device 100.
Thecontrol device 100 typically has a volume button that can control the volume up or down, and may also have a mute button that directly controls the volume to zero. As shown in fig. 6, when the user wants to adjust the audio state of thepower amplifier device 500, the user may press a key related to thecontrol apparatus 100, and then input a key command to thedisplay device 200. After receiving the key instruction, thedisplay device 200 analyzes the key instruction to determine that the user needs to adjust the target audio state of thepower amplifier device 500; thedisplay device 200 generates an audio state control instruction according to the target audio state. Then, thedisplay device 200 sends the audio state control instruction to thepower amplifier device 500 so that thepower amplifier device 500 adjusts the current audio state to the target audio state, and meanwhile, thedisplay device 200 also sends an audio state request instruction to thepower amplifier device 500 to request thepower amplifier device 500 to report the adjusted target audio state to thedisplay device 200, so that thedisplay device 200 can display the current target audio state of thepower amplifier device 500.
In the process that thedisplay device 200 displays the current target audio state of thepower amplifying device 500, thecontroller 250 of thedisplay device 200 may be configured to: first, a key command for adjusting the audio state of thepower amplifier device 500, which is input by a user through thecontrol apparatus 100, is received. And then, analyzing the key instruction to obtain a target audio state of thepower amplifier equipment 500 to be adjusted. And then sends an audio state request command and an audio state control command for adjusting the audio state to thepower amplifier device 500. And finally, receiving and displaying the target audio state sent back by thepower amplifier equipment 500.
As can be seen, even though some existingpower amplifier devices 500 do not report their own audio states to thedisplay device 200 actively, thedisplay device 200 in the embodiment of the present application may also send an audio state request instruction to thepower amplifier devices 500 actively after receiving a key instruction of a user for operating thepower amplifier devices 500, and request thepower amplifier devices 500 to report the adjusted target audio states to thedisplay device 200. Therefore, the problem that the audio state of thepower amplifier equipment 500 cannot be displayed by thedisplay equipment 200 due to the fact that part of thepower amplifier equipment 200 cannot report the audio state is solved. Meanwhile, it is ensured that the user can know the current audio state of thepower amplifier device 500 in time.
As described in the foregoing embodiments, the audio states of thedisplay apparatus 200 include a volume adjustment state having a volume and a mute state having no volume.
Fig. 7 shows a second flowchart of displaying the audio status of thepower amplifier device 500 by thedisplay device 200 according to some embodiments. As shown in fig. 7, when the user adjusts the volume of thedisplay apparatus 200 using thecontrol device 100, the user may press a volume key on thecontrol device 100, such as volume "+" or volume "-" on a remote controller. At this time, thecontrol apparatus 100 sends a key command for pressing the volume key to thedisplay device 200. After receiving the instruction, thedisplay device 200 analyzes the target volume that needs to be adjusted, for example, increasing 10 volume values or decreasing 10 volume values. Then, thedisplay device 200 generates a volume control command based on the target volume and sends the volume control command to thepower amplifier device 500, so as to control thepower amplifier device 500 to adjust the current volume to the target volume; meanwhile, in order to enable thepower amplifier device 500 to report the adjusted volume to thedisplay device 200 more timely, thedisplay device 200 further needs to send a volume request instruction to thepower amplifier device 500 to request thepower amplifier device 500 to send the target volume back to thedisplay device 200 after adjusting the volume. Furthermore, thedisplay device 200 may display the current target volume provided by thepower amplifier device 500, so that the user can conveniently view and know the volume condition of the currentpower amplifier device 500.
Generally, the user presses the volume key once for a short time, on the order of a fraction of a second or milliseconds, and the like, and each time the volume key is pressed may indicate to control the volume to increase by one value or decrease by one value. However, in some embodiments, the user may press the volume button for a long time in order to adjust the volume more quickly. The volume adjustment is generally related to the time for the user to press the volume key, and the longer the volume key is pressed, the larger the variation value of the target volume to be adjusted is. For example, if the user presses the volume "+" button for 2 seconds, then the corresponding target volume may require 20 volume values to be added; alternatively, if the user presses the volume "-" button for 1 second, the corresponding target volume may be reduced by 10 volume values.
In the case where the user adjusts the volume of thepower amplifier device 500 through the volume key of thecontrol apparatus 100, thecontroller 250 of thedisplay device 200 may be configured to: first, when the key command indicates a command sent by the user to press a volume key of thecontrol device 100, the key command is analyzed to obtain a target volume to be adjusted by thepower amplifier 500. Then, a volume request command and a volume control command for adjusting the volume are sent to thepower amplifier device 500. And finally, receiving the adjusted target volume sent back by thepower amplifier equipment 500.

In some embodiments, in order to facilitate the user to view the target volume adjusted by thepower amplifier device 500, thedisplay device 200 needs to display a specific target volume on the user interface after receiving the target volume sent back by thepower amplifier device 500. As shown in fig. 8, the target volume may be displayed on the user interface in the form of a volume bar, and the length of the volume bar indicates the magnitude of the target volume. Meanwhile, in order to enable the user to know the specific value of the target volume, as shown in fig. 8, thedisplay device 200 further displays specific data of the current target volume, for example, 30, 50, etc., at the bottom of the volume bar.
In the above-described process of displaying the target volume, thecontroller 250 of thedisplay apparatus 200 may be further configured to: first, the adjusted target volume sent back by thepower amplifier 500 is received. Then, the target volume is displayed on the user interface of thedisplay device 200 in the form of a volume bar.
Fig. 9 shows a third flowchart of displaying the audio status of thepower amplifier device 500 by thedisplay device 200 according to some embodiments. As shown in fig. 9, when the user controls thepower amplifier 500 to mute using thecontrol apparatus 100, the user may press a mute button on thepower amplifier 500. At this time, thecontrol device 100 sends a key instruction for pressing the mute key to thedisplay device 200. After receiving the instruction, thedisplay device 200 analyzes that thepower amplifier device 500 needs to be adjusted to a mute state, that is, the volume value is zero. Then, thedisplay device 200 generates a volume control instruction based on the mute state and sends the volume control instruction to thepower amplifier device 500, so as to control thepower amplifier device 500 to adjust the current audio state to the mute state; meanwhile, in order to enable thepower amplifier device 500 to report the adjusted mute state to thedisplay device 200 more timely, thedisplay device 200 further needs to send a volume request instruction to thepower amplifier device 500 to request thepower amplifier device 500 to send the current mute state back to thedisplay device 200 after the audio state is adjusted. Furthermore, thedisplay device 200 may display the current mute state provided by thepower amplifier device 500, so as to facilitate the user to watch and know the audio state of the currentpower amplifier device 500.
In the case where the user adjusts the audio state of thepower amplifier device 500 through the mute key of thecontrol apparatus 100, thecontroller 250 of thedisplay device 200 may be further configured to: first, when the key command indicates a command transmitted by the user pressing the mute key of thecontrol device 100, the key command is analyzed to determine that thepower amplifier 500 needs to be adjusted to the mute state. Then, a volume request command and a volume control command for adjusting the volume are sent to thepower amplifier device 500. The volume control command is used to adjust the current audio state of thepower amplifier 500 to a mute state.
FIG. 10 illustrates a second schematic view of a user interface of adisplay device 200 according to some embodiments.
In some embodiments, in order to facilitate the user to view the adjusted audio state of thepower amplifier device 500, thedisplay device 200 needs to display a mute flag on the user interface after receiving the mute state sent back by thepower amplifier device 500. As shown in fig. 10, the mute state may be displayed on the user interface in the form of a mute flag.
In the above-described process of displaying the mute state, thecontroller 250 of thedisplay apparatus 200 may be further configured to: first, the adjusted mute state sent back by thepower amplifier 500 is received. Then, the mute state is displayed on the user interface of thedisplay apparatus 200 in the form of a mute flag.
In addition, when the user controls the volume of thepower amplifier device 500 by using the volume key of thecontrol apparatus 100, if the volume "-" key is pressed to reduce the volume of thepower amplifier device 500 to zero, thedisplay device 200 may directly display the mute flag as shown in fig. 10 on the user interface after receiving the current target volume of thepower amplifier device 500.
In this embodiment, no matter whether thepower amplifier device 500 is configured to actively report the audio status to thedisplay device 200, after thepower amplifier device 500 is connected to thedisplay device 200 through the ARC and the user controls the audio status of thepower amplifier device 500 through thecontrol device 100, thedisplay device 200 may send the audio status control command and the audio status request command to thepower amplifier device 500. The audio state control instruction is used for controlling thepower amplifier equipment 500 to adjust the current audio state to be the target audio state; and an audio state request instruction, which requests thepower amplifier device 500 to actively send the adjusted target audio state back to thedisplay device 200. Thus, thedisplay device 200 can display the current target audio state of thepower amplifier device 500 for the user. Therefore, thedisplay device 200 in the embodiment of the present application may further control thepower amplifier device 500 to actively report the audio state according to the control of the user, so as to avoid a problem that the user experience is affected because part of thepower amplifier devices 500 may not actively report the audio state.

In order to solve the problem that the foregoing part of thepower amplifier device 500 cannot actively report the audio state to thedisplay device 200, as shown in fig. 11, thepower amplifier device 500 provided in this embodiment may further specifically adjust the current audio state to the target audio state according to an audio state control instruction sent by thedisplay device 200. In addition, thepower amplifier device 500 may also report the adjusted target audio state to thedisplay device 200 according to the audio state request instruction sent by thedisplay device 200.
For example, the audio state control command sent by thedisplay device 200 to thepower amplifier device 500 indicates that the volume of thepower amplifier device 500 needs to be increased to the target volume 50. Then thepower amplifier device 500 adjusts the current volume 20 to the target volume 50, and then reports the target volume 50 to thedisplay device 200.
Or, thedisplay device 200 indicates that the volume of thepower amplifier device 500 needs to be reduced to the target volume 10 in the audio state control command sent to thepower amplifier device 500. Then, thepower amplifier device 200 adjusts the current volume 40 to the target volume 10, and then reports the target volume 10 to thedisplay device 200.
In the process of adjusting the audio state and reporting the audio state by thepower amplifier device 500, the controller of thepower amplifier device 500 may be configured to: first, an audio state request instruction and an audio state control instruction for adjusting an audio state transmitted by thedisplay apparatus 200 are received. And then, adjusting the current audio state to the target audio state according to the audio state control instruction.

In the case that the audio state control instruction is used to control the volume of thepower amplifier device 500, the controller of thepower amplifier device 500 may be further configured to: and responding to the audio state control instruction, and adjusting the current volume of thepower amplifier equipment 500 to the target volume. And transmits the adjusted target volume back to thedisplay device 200 according to the audio status request instruction.
And, in case that the audio state control instruction is used to control thepower amplifier device 500 to mute, the controller of thepower amplifier device 500 may be further configured to: and in response to the audio state control instruction, adjusting the current audio state of thepower amplifier equipment 500 to a mute state. And sends the adjusted mute state back to thedisplay device 200 according to the audio state request instruction.
In this embodiment of the application, thepower amplifier device 500 is connected to thedisplay device 200 through the ARC of thedisplay device 200, and after the connection, no matter whether thepower amplifier device 500 can actively report the audio status of itself to thedisplay device 200, thedisplay device 200 sends an audio status request instruction to thepower amplifier device 500, so that thepower amplifier device 500 sends the adjusted target audio status back to thedisplay device 200. Further, the problem that the user experience is affected due to the fact that part of thepower amplifier equipment 500 cannot actively report the audio state is avoided.
In the embodiment of the present application, the communication process between thedisplay device 200 and thepower amplifier device 500 is implemented based on a CEC (Consumer Electronics Control) command. That is, thedisplay device 200 may control the behavior of thepower amplifier device 500, such as volume adjustment, mute, standby power on, etc., by sending the CEC command, and thepower amplifier device 500 may report the audio status of itself to thedisplay device 200 by sending the CEC command.
When thedisplay device 200 communicates with thepower amplifier device 500 based on the CEC command, the process of thedisplay device 200 sending an instruction to thepower amplifier device 500 is as follows:
first, after the user presses a key command of thecontrol apparatus 100, thedisplay device 200 transmits a key command of the user, for example, a 0x44 command, to thepower amplifier device 500, where the key command carries 1 parameter, for example, 0x41, 0x42, 0x43, and the like.
