As shown in fig. 4, the system of the display device is divided into three layers, i.e., an application layer, a middleware layer and a hardware layer from top to bottom.

The Application layer mainly includes common applications on the television and an Application Framework (Application Framework), wherein the common applications are mainly applications developed based on the Browser, such as: HTML5 APPs; and Native APPs (Native APPs);

an Application Framework (Application Framework) is a complete program model, and has all basic functions required by standard Application software, such as: file access, data exchange …, and interfaces (toolbars, status bars, menus, dialog boxes) for use of these functions.

Currently, on the display device 200, the ARC (audio return) power amplifier of HDMI is largely used due to its outstanding sound playing effect. In actual use, however, if the user continuously controls the volume keys using the remote controller, for example, long-pressing the volume "+" and volume "-" keys, the remote controller may distribute an excessive volume key message to the display device 200. If the volume key messages sent by the remote controller are too many, the display device 200 processes the situation that the volume may be changed discontinuously, such as abrupt change or jump, by processing a plurality of volume key messages at one time; alternatively, the display device 200 is always processing the volume key message, which may result in a situation where other control messages cannot be processed in time.

In order to solve the above-mentioned problem of abrupt change of volume and processing delay of other control messages caused by long pressing of a volume key of a control device 100 such as a remote controller by a user, the embodiment of the present application provides a display device 200.

The user can control the volume of the display device 200 through the volume key on the control apparatus 100 such as a remote controller according to his or her own needs. Since the volume adjusted at one time by pressing the volume key for a short time may be difficult to satisfy the user's demand, the user may select to press the volume key for a long time. As shown in fig. 5, when the user presses the volume key for a long time, the control apparatus 100 needs to continuously send a plurality of volume key messages to the display device 200, and during the long pressing of the volume key, the user may also send other control messages to the display device 200, such as a direction key, a confirmation key, a function key, or some other CEC message. When the control message sent by the control device 100 is too many, in order to avoid the display device 200 processing too many volume key messages at one time, the display device 200 may only keep a part of the volume key messages corresponding to the time of the long pressing operation for one time to process, and the final volume is not adjusted to be too high, thereby avoiding the situation of abrupt change of the volume.

A CEC (Consumer Electronics Control) message refers to a message transmitted between the Control apparatus 100 and the display device 200 based on a CEC protocol. All external devices connected to the HDMI interface of the display device 200 can be controlled by a single control apparatus 100, typically by means of CEC messages. In the embodiment of the present application, the CEC message that the control apparatus 100 sends to the display device 200 is mainly processed and is also referred to as a control message. The CEC message includes some key messages and other forms of control messages and the like transmitted by the control device 100, and also includes a volume key message and other key messages in the key messages.

In the above-described process of processing the volume key message, the controller 250 of the display device 200 may be configured to: and receiving all control messages sent by the control device 100 within a preset time, wherein the control messages include volume key messages and other control messages. The preset time is used to indicate a time when the user presses the volume key of the control device 100, that is, a time when the user presses the volume key for a long time. Then, the controller 250 retains the first preset number of volume key messages among all the control messages, constituting the target volume key message set. Finally, the volume key messages in the target volume key message set are sequentially processed, and the current volume of the display device 200 is adjusted.

The volume key message in this embodiment refers to a key message sent by the user "long pressing" the volume "+" key or the volume "-" key on the control device 100, and in this embodiment, the preset time is used to indicate the time for the user to "long press" the volume key, for example, 2s, 3s, and the like.

Fig. 6 illustrates a schematic diagram of a sudden change in volume of the display device 200 according to some embodiments. As shown in fig. 6, if the user wants to turn the volume of the display device 200 up at once without knowing how long the volume key is pressed to adjust to the desired target volume, the user may press the volume key for too long, i.e., the preset time is too long. The control apparatus 100 may send too many volume key messages and other control messages to the display device 200, and the current display device 200 may adjust the volume to the maximum directly after processing all the volume key messages in sequence in order to adjust the volume according to the user's instruction, and the maximum volume value will inevitably affect the current user experience of the user.

Fig. 7 illustrates a schematic diagram of volume adjustment of the display device 200 according to some embodiments. As shown in fig. 7, when the control apparatus 100 sends too many volume key messages, the display device 200 in the embodiment of the present application only retains a part of the volume key messages for processing, and thus the finally adjusted volume is not too large as shown in fig. 6.

As can be seen, the display device 200 in the embodiment of the present application avoids the situation that the volume of the display device changes suddenly due to excessive processing of the volume key message, and avoids the situation that other control messages cannot be processed in time due to excessive processing of the volume key message.

Furthermore, as described above, the display device 200 may receive other control messages during the process of receiving the volume key message, that is, the volume key message may be interspersed with other control messages at irregular time, and these messages need to be processed by the display device 200 in turn. Since the control messages issued by the control apparatus 100 are CEC messages, the display device 200 allocates a message processing thread to process the messages one by one according to the processing capability of the CEC bus. If the volume key messages are too many, the longer the message processing thread or the CEC bus is occupied, and further other CEC messages cannot be processed in time.

In the embodiment of the present application, only a part of the volume key messages is reserved for processing, which can also greatly reduce the time for the display device 200 to process the volume key messages, thereby increasing the speed for the display device 200 to process other CEC messages. In some embodiments, the display apparatus 200 may determine how many volume key messages need to be retained for processing, i.e., determine the first preset number, according to the rate at which the control device 100 transmits the volume key messages. If the rate is higher, it indicates that the number of volume key messages sent by the control device 100 per unit time is higher, and at this time, a relatively small number of volume key messages may be selected for processing; if the rate is smaller, it means that the control apparatus 100 has a smaller number of volume key messages transmitted per unit time, and at this time, the volume key message may be appropriately selected for processing, or all volume key messages may be selected for processing. The preset time in the embodiment of the present application may include at least one unit time, and the determining of the first preset number may also be determined according to the length of the preset time. The unit time in the embodiment of the present application may be in units of seconds.

For example, if the current volume key message transmission rate of the control apparatus 100 is 50 per second, the display device 200 may select only 10 volume key messages per second to be processed, and the other volume key messages are discarded, and at this time, if the preset time is 3 seconds, which includes 3 unit times, the first preset number may be 30. Alternatively, if the preset time is 1 second, the first preset number is 10.

If the preset time includes only one unit time, the display apparatus 200 only needs to process the first 10 volume key messages when processing all the volume key messages in the unit time, and the other volume keys are discarded. If the preset time includes three unit times, the display device 200 needs to process the first 10 volume key messages per unit time, respectively, and the other volume key messages per unit time are also discarded.

In this embodiment of the application, the display device 200 needs to process all volume key messages of a first preset number within a preset time, and then sequentially process other CEC messages received within the preset time.

In this process, the controller 250 of the display apparatus 200 may be configured to: the transmission rate at which the control apparatus 100 issues the volume key message to the display device 200 is detected. Then, according to the sending rate, a first preset number of volume key messages needing to be reserved is determined. In some embodiments, the processing of the volume button message by the display device 200 is performed through a series of codes, and an initial message queue and a temporary message queue may be previously declared in the display device 200 at the time of the processing. The initial message queue is used to store all control messages issued by the control device 100, for example, a volume key message, a number key message, a direction key message, or some other CEC messages.

In some embodiments, referring to the foregoing, the volume key messages sent by the control apparatus 100 to the display device 200 are all stored in the initial message queue, and some other control messages may also be stored in the initial message queue during the process of storing the volume key messages. If the user presses the volume key for a long time to adjust the volume, the control device 100 also transmits a plurality of volume key messages. If there are too many volume key messages, there are too many volume key messages in the initial message queue, so that the display device 200 may be in a state of processing the volume key messages for a long time without having too much time to process other control messages in the initial message queue.

Also, if the display device 200 directly processes all the volume key messages, a sudden change in the volume of the display device 200 may be caused.

In order to avoid the above-described problem on the display device 200 when the user presses the volume key of the control apparatus 100 for a long time, in some embodiments, as shown in fig. 8, the display device 200 may also move the volume key message stored in the initial message queue for a preset time to a temporary message queue prepared in advance. And, when moving, only move the first preset number of volume key messages, and the redundant volume key messages in the initial message queue can be discarded, and the initial message queue at this time is the pending message queue. And then, transferring the target volume key message set consisting of the volume key messages with the first preset number in the temporary message queue back to the tail of the message queue to be processed to wait for processing.

As can be seen from the foregoing, the preset time may include at least one unit time, and the number of volume key messages to be retained in each unit time is a second preset number. The second preset number is determined according to a rate at which the control device 100 issues the volume key messages, and when the volume key messages are moved into the temporary message queue, the display device 200 moves the volume key messages of the second preset number per unit time in the initial message queue. When the preset time only comprises one unit time, the first preset quantity is the same as the second preset quantity; when the preset time includes two or more unit times, the first preset quantity is the sum of the second preset quantities in each unit time.

In this process, as shown in fig. 9, the controller 250 of the display apparatus 200 may be configured to: first, an initial message queue and a temporary message queue are allocated to the display apparatus 200 in advance, and all control messages within a preset time are sequentially stored in the initial message queue. And then, sequentially moving the volume key messages of the second preset number in each unit time in the initial message queue to the temporary message queue respectively to form a target volume key message set, and deleting the remaining volume key messages in each unit time in the initial message queue to obtain a message queue to be processed. And then, integrally storing the volume key messages in the target volume key message set into the tail of the message queue to be processed to obtain a target message queue. Finally, each volume key message in the target message queue is processed in sequence, and then the current volume of the display device 200 is adjusted.

Because the message queue is a first-in first-out queue, the target volume key message set needs to be stored in the tail of the message queue to be processed in sequence. Then, the display apparatus 200 sequentially processes the respective control messages in the order of the queue from the control message at the head of the queue.

The display device 200 in the embodiment of the present application may also implement, through the initial message queue and the temporary message queue, an operation of intercepting a part of the volume key message to process in the process of the user long-pressing the volume key to adjust the volume of the display device 200. Further, it is possible to prevent the display device 200 from processing an excessive volume key message to cause a sudden change in the volume of the display device, and to prevent other control messages from being processed in time.

In general, the initial message queue stores key messages in real time, that is, receives control messages that the control device 100 continues to send after receiving the volume key message and other control messages corresponding to the current long-press volume key operation. However, in order to avoid the influence of the subsequent control message on the processing process of the volume key message corresponding to the long-press operation, in the embodiment of the present application, only all the control messages within the time of the long-press operation are selected for processing, that is, all the control messages within the preset time are processed. That is, only the control messages within the preset time are saved in the initial message queue.

Then, after the display device 200 moves or deletes the volume key message in the initial message queue, the initial queue message queue becomes a pending message queue. The display device 200 stores the target volume key message set in the temporary message queue to the tail of the initial message queue.

In terms of the user operating the control device 100, pressing the volume key once for a long time is to adjust the volume once; in the angle of the display device 200, after receiving a plurality of volume key messages corresponding to a long-press volume, the volume may be adjusted once as a whole after processing one volume key message, or may be adjusted once after processing several volume key messages. If the manner in which the volume is adjusted by the display device 200 is not limited, the volume change actually experienced by the user may not be uniform but may jump. For example, the volume jumps first from 10 to 11, 11 to 14, 14 to 15, etc.

Therefore, in order to ensure that the volume adjusted by the display device 200 finally shows a uniform change, in some embodiments, as shown in fig. 10, the display device 200 also needs to gradually adjust the volume in fixed steps until the volume is adjusted to the target volume. The fixed step length referred in the embodiment of the present application is determined according to the property of the power amplifier of the display device 200, for example, the property specifies how much the power amplifier changes the volume value in response to the volume key message.

In this process, the controller 250 of the display apparatus 200 may be configured to: and sequentially processing the volume key messages in the target volume key message set to obtain the target volume of the volume adjustment operation. Then, the positioning control on the volume bar for displaying the volume level on the control display 260 is gradually moved to the target volume in fixed steps.

FIG. 11 illustrates a schematic diagram of a volume bar display according to some embodiments. As shown in fig. 11, in some embodiments, if the display device 200 obtains the target volume of 50 according to the volume key message corresponding to the user long-pressing the volume key, and the positioning control on the volume bar of the display device 200 is currently located at the volume of 10, the display device 200 may gradually move the positioning control by a fixed step size of 5, and sequentially move the positioning control to the volume of 15, the volume of 20, the volume of … …, the volume of 45, and the volume of 50.

And, in some embodiments, in order to allow the user to intuitively see the change of the volume while hearing the change of the volume, the display device 200 may further display a corresponding volume value, such as the

volume

10, 15, 20, etc., at a position where the positioning control stays each time.

In this process, the controller 250 of the display apparatus 200 may be further configured to: during the movement of the positioning control in fixed steps, the display 260 is controlled to display the corresponding volume value each time the positioning control is stopped. And the position at which the volume value is specifically displayed may be below the volume bar as shown in fig. 11. Alternatively, if the volume is displayed laterally on the display page of the display 260, the specific display value may be displayed on the left and right sides of the volume bar, for example, as shown in fig. 12.

In the embodiment of the present application, the initial message queue, the pending message queue, and the target message queue are all essentially a message queue, and they are named for many times only for distinguishing different states of the message queue in the processing process.

As described in the foregoing embodiment, the initial message queue receives the control message in real time, and after the user presses the volume key for a long time and the display device 100 stores a plurality of volume key messages corresponding to the long time period of pressing the volume key into the initial message queue, the display device 200 intercepts and processes the volume key messages in the manner described above in this embodiment. After the volume adjustment process corresponding to the current long-press operation is finished, if the user presses the volume key for a long time after a period of time, the display device 200 may still intercept and process the volume key message within the next preset time in the manner described above.

It should be noted that, in the foregoing embodiment, the process of changing the volume on the display device 200 is described by taking the user pressing the volume "+" key for a long time as an example. In some other embodiments, the user may also operate by pressing the volume "-" key for a long time, but the display device 200 performs the specific processing in the manner described above.

The control device 100 described in the embodiment of the present application may not only refer to a physical remote controller, but also to a virtual remote controller installed on a mobile terminal, for example, a virtual remote controller installed on a smartphone.

As can be seen from the above, the display device 200 in the embodiment of the present application may receive a plurality of volume key messages sent by a user by pressing the volume key of the control apparatus 100 and other control messages sent by the control apparatus 100, and the display device 200 only retains a part of all the volume key messages for processing, so as to avoid a situation that the volume of the display device 200 changes suddenly due to processing too many volume key messages and avoid a situation that other control messages cannot be processed in time due to processing too many volume key messages.

In addition, in order to avoid the display device 200 from processing too many volume key messages, in this embodiment, a method for processing a volume key message is also provided, which may be specifically implemented in the display device 200 in the foregoing embodiment. The method may comprise the steps of: first, all control messages sent by the control device 100 within a preset time are received, where the control messages include a volume key message and other control messages, and the preset time is used to indicate a time when a user presses a volume key of the control device 100. Then, the first preset number of volume key messages are reserved in all the control messages to form a target volume key message set. Finally, the volume key messages in the target volume key message set are sequentially processed, and the current volume of the display device 200 is adjusted.

In some embodiments, the method may further comprise: allocating an initial message queue to the display device 200 in advance; sequentially storing all control messages in a preset time into an initial message queue; the preset time comprises at least one unit time, and the control messages received in each unit time are stored in the initial message queue.

In some embodiments, the method may further comprise: allocating a temporary message queue to the display device 200 in advance; sequentially moving a second preset number of volume key messages in each unit time in the initial message queue to the temporary message queue respectively to form a target volume key message set; and deleting the volume key messages remained in each unit time in the initial message queue to obtain a message queue to be processed.

In some embodiments, the method may further comprise: integrally storing the volume key messages in the target volume key message set into the tail of the message queue to be processed to obtain a target message queue; and sequentially processing each volume key message in the target message queue, and adjusting the current volume of the display device 200.

In some embodiments, the method may further comprise: sequentially processing the volume key messages in the target volume key message set to obtain the target volume of the volume adjustment operation; the positioning control on the volume indicator bar on the control display 260 for displaying the volume level is gradually moved to the target volume in fixed steps.

In some embodiments, the method may further comprise: during the movement of the positioning control in fixed steps, the display 260 is controlled to display the corresponding volume value each time the positioning control is stopped.

In some embodiments, the method may further comprise: detecting a transmission rate at which the control apparatus 100 transmits a volume key message to the display device 200 in a unit time; and determining a second preset number of the volume key messages needing to be reserved according to the sending rate.
