Fig. 2A-2C illustrate diagrams of a GUI500 provided by the display device 200 by operating the mobile terminal 100B.

As shown in fig. 2A, in order to display the interface 51 of the display device 200, in the prior art, if the user needs to adjust the image quality of the display interface of the display device 200, the image quality adjustment dialog 51-1 on the right side of fig. 2A needs to be called up. The image quality adjustment dialog 51-1 includes a plurality of function items and progress bars for the user to adjust the image quality of the display interface of the display device. And then, the remote controller is utilized to move the focus to the progress bar of the functional item to be adjusted by pressing the direction key on the remote controller, and then the plus key or the minus key on the remote controller is pressed to move the control position of the progress bar so as to change the value of the functional item. For example, if the contrast value needs to be adjusted from 1 to 100, the direction key on the remote controller needs to be pressed first to move the focus to the progress bar of the contrast, and then the add key on the remote controller needs to be pressed 99 times to adjust the contrast value from 1 to 100.

Embodiments of the present application adjust the image quality of a display device using a mobile terminal, and fig. 1E-1L schematically illustrate one GUI400 provided by the mobile terminal 100B.

In the embodiment of the application, the mobile terminal comprises a remote connection application, the display device comprises a corresponding remote connection application of the display device end, and the mobile terminal can be connected with the display device through the remote connection application. Specifically, as shown in fig. 1E, the remote connection application page 41 of the mobile terminal may automatically detect whether the mobile terminal is connected to the display device after the user opens the remote connection application of the mobile terminal. If the display equipment is not connected, a prompt message dialog box pops up on a remote connection application interface of the mobile terminal: and if no equipment is connected, selecting the display equipment needing to be connected. And cancel and select options are displayed in the prompt message dialog. The user may press a select key directly on the mobile terminal causing the mobile terminal to jump from the remote connection application page 41 of FIG. 1E to the device list page 42 of FIG. 1F.

In the device list page 42 of fig. 1F, a list of display devices (connectable display devices, which are also display devices of the same local area network) that can establish a connection with the mobile terminal is included. If there is a connected display device in the list, the user will automatically connect the display device when opening the remote connection application. Because the connection is established in advance, the remote connection application of the display device already records the UUID (universal Unique Identifier) of the mobile terminal, and can judge that the mobile terminal exists in the connected mobile terminal list, so that the password frame is not displayed any more, and the connection is automatically completed.

Fig. 3 is a logic diagram of a method for establishing a connection between a mobile terminal and a display device. The mobile terminal remote connection application and the display device remote connection application are connected through an MQTT (Message Queuing Telemetry Transport) protocol, and communication is performed in a manner of sending topic to each other. MQTT is a lightweight message publish/subscribe protocol, which is an ideal solution for implementing a message push server based on a mobile phone client (mobile terminal). The MQTT protocol is realized by communication between a client and a server, and in the communication process, the MQTT protocol has three identities: publisher (Publish), Broker (Broker) (server), subscriber (Subscribe). The message publisher and the message subscriber are clients, the message broker is a server, and the message publisher can be a subscriber at the same time.

The transmitted messages of the MQTT are divided into: theme (Topic) and load (payload) two parts: (1) topic, which can be understood as the type of message, after a subscriber subscribes (Subscribe), the subscriber will receive the message content (payload) of the Topic; (2) payload, which may be understood as the content of a message, refers to content that a subscriber specifically wants to use.

When the image quality of the display device needs to be adjusted by using the mobile terminal, the mobile terminal needs to be connected with the display device in advance. It may be that the mobile terminal and the display device establish a connection through a local area network (unified WiFi network). The WiFi MAC address of each mobile terminal is fixed and unique, the UUID (the unique identifier of the mobile terminal) is generated by using the WiFi MAC address of the mobile terminal, the mobile terminal actively initiates connection and sends topic for verifying whether the address is legal or not, and the topic carries the UUID information of the mobile phone. And after receiving the topic, the display device judges the mobile terminal and judges whether the UUID of the mobile terminal is already in the device list connected with the display device. And if the mobile terminal exists in the device list connected with the display device, connecting the display device and the mobile terminal. And if the mobile terminal does not exist in the device list connected with the display device, popping up a password input dialog box on a display interface of the mobile terminal. The user may enter a pre-known password in the password input dialog and send the entered password to the display device. And the display equipment judges whether the password input by the user is consistent with the password pre-stored by the display equipment or not, and if so, the display equipment is connected with the mobile terminal.

After the mobile terminal and the display device establish a connection, the remote connection application page of fig. 1E may be returned. The user clicks on the personal center option in FIG. 1E, and the mobile terminal jumps from the remote connectivity application page 41 of FIG. 1E to the personal center page 43 in the remote connectivity application of FIG. 1G, which includes an image quality adjustment function entry: picture Setting, the user can click on the image quality adjustment function entry, causing the mobile terminal to jump from the personal center page 43 of fig. 1G to the image quality adjustment page 44 of fig. 1H.

In the image quality adjustment page of fig. 1H, image quality-related adjustment options such as background brightness, picture mode, contrast, and brightness are included. The user directly adjusts the options in the image quality adjusting page of the mobile terminal, and the display effect is directly reflected on the display equipment according to the option value adjusted on the mobile terminal. The specific adjusting mode is as follows: the user drags the tip of progress bar behind the point touch progress bar, realizes the change of option numerical value, perhaps, directly the blank region of point touch numerical value scope strip for the tip direct movement of progress bar realizes the change of option numerical value to the position of point touch.

Responding to an instruction input by a user on the mobile terminal for adjusting at least one function item according to the information of the function item displayed on the mobile terminal, and adjusting the corresponding function item on the display equipment. For example, the user adjusts the value of the function item of the brightness function item on the mobile terminal from 50 of the brightness function item shown in fig. 1H to 70 shown in fig. 1I.

Here, as shown in fig. 2D, when the user adjusts the brightness function item on the mobile terminal, the display device does not pop up a corresponding image quality adjustment dialog box, and does not interrupt the program currently played by the display device to enter the image quality adjustment page, but the image of the display device automatically displays the adjusted brightness effect after the brightness function item is adjusted by the mobile terminal. The image quality adjusting scheme can avoid program interruption, and can adjust the image quality in the program playing process, so that the image quality adjusting effect corresponding to the program is better.

In some embodiments, an option may be provided on the mobile terminal or on the display device for opening an image quality adjustment interface or dialog box on the display device. As shown in fig. 2B, the image quality adjustment interface on the display device corresponds to the image adjustment interface of the mobile terminal, and after the mobile terminal adjusts the relevant option, the value of the corresponding option may be checked on the image adjustment interface corresponding to the display device to see whether the value is consistent with the value on the mobile terminal. For example, the brightness function item of the mobile terminal is adjusted from 50 shown in fig. 1H to 70 shown in fig. 1I, and the brightness function item of the display device image quality adjustment interface is also adjusted from 50 shown in fig. 2B to 70 shown in fig. 2C. Thus, whether the image quality adjustment is successful or not can be visually verified from the data.

In some embodiments, after the user opens the image quality adjustment page on the mobile terminal, all function items related to image quality adjustment may be presented to the user. The user may select the function items that need to be adjusted from among the function items, so that the display apparatus transmits only information of the function items selected by the user to the mobile terminal. Fig. 1J is a schematic diagram of an image quality adjustment interface of a mobile terminal, where only information of a function item selected by a user is displayed: a brightness function item, a color function item, and a hue function item. Therefore, the user can adjust the image quality in a targeted manner, and the efficiency of adjusting the image quality is further improved.

In some embodiments, the function items related to image quality adjustment may include two types: an active term and a passive term. An active item herein refers to a functional item that is not dependent on other functional items. And a passive item is a functional item that is subordinate to other functional items. As shown in fig. 1K, the image quality adjustment interface of the mobile terminal includes a plurality of passive terms of contrast, brightness, color, sharpness, and image size. The active item image mode shown in fig. 1K takes on a value of "vivid", and the passive item takes on a value: contrast 60, brightness 45, color 65, color 0, sharpness 10, and image size are wide. The image of the display device at this time is displayed in a bright-colored manner according to the image mode value.

If the user changes the value of the image mode in the mobile terminal to the standard shown in fig. 1L, the value of the passive term is changed as follows: the contrast 50, brightness 50, color 60, color 0, sharpness 10 and image size are wide, and the display device image at this time is also displayed with the image mode value "standard". The value situation of the passive item corresponds to the value situation of the image mode, and if the user changes the value of the image mode from the standard shown in fig. 1L to the bright-colored image shown in fig. 1K, the value situation of the passive item is changed again as follows: contrast 60, brightness 45, color 65, color 0, sharpness 10, and image size are wide.

The user can also adjust the value of the passive item independently, for example, the contrast in the "standard" item in the image mode is changed from 50 to 70, and then the mobile terminal automatically saves the contrast of the "standard" item in the image mode. If the user adjusts the image mode from 'bright-colored' to 'standard' of the image mode, the value taking situation of the passive item of the 'standard' of the image mode is changed as follows: contrast 70, brightness 50, color 60, color 0, sharpness 10, and image size are wide.

With reference to the schematic flow chart of the display device end of the image quality adjusting method shown in fig. 4, the specific implementation process of the above embodiment is as follows:

in the embodiment of the application, the remote connection application of the mobile terminal belongs to Mqtt Client, and the display device comprises an Mqtt Server and an Mqtt Client. The Mqtt client is connected to the Mqtservicer terminal by using a fixed user name and a password. The mobile terminal Mqtt client and the display device Mqtt client are both publishers and subscribers of messages, and the messages are sent to the Mqtt server end and then sent to the other Mqtt client in the communication between the mobile terminal Mqtt client and the display device Mqtt client. The Mqtt Server is only responsible for message passing (responsible for mutual message passing between the display device client and the mobile terminal client, and supporting one display device to connect with a plurality of mobile terminals), and all functional processing of the display device is processed in an Mqtt client part in the display device remote connection application.

Taking each function item of the display device related to image quality adjustment as a menu, the data structure of menu is shown in table 1:

name of field	Means of
		menu_id	The unique identifier of menu is also the unique identifier of interaction between the mobile phone terminal and the television terminal
menu_name	Display name of menu
		menu_value	Current value of menu
menu_flag	Whether menu needs to be grayed or not

Data structure of table 1menu

The topic content of the communication between the mobile terminal and the display device includes two parts, namely menu and action, and the action is divided into several values as shown in table 2.

TABLE 2 values of action

When the user remotely connects the application at the mobile terminal and opens the image quality adjustment interface, the mobile terminal sends topic with action of get _ menu _ info to the display device (first to mqttservice and then to mqtt client). When a user clicks a certain function item on the image quality adjustment interface of the mobile terminal or modifies the certain function item, the mobile terminal sends topic with action of get _ value and set _ value to the display device.

After receiving topic sent by the mobile terminal, the display device remote connection application (Mqtt client part) first determines aticon.

If the action is get _ menu _ info, the display equipment remote connection application acquires all function items, namely the value and the flag of menu, at one time through an interface provided by a bottom layer audio/video module jar packet, converts the function items into a data format required by the mobile terminal remote connection application, and sends the data format to the mobile terminal remote connection application, and the mobile terminal remote connection application performs interface display according to the received data.

If the action is get _ value, obtaining the current menu value and flag according to menu _ id and an interface provided by a bottom layer audio/video module jar packet to form topic, sending the topic to the mobile terminal remote connection application, and displaying an interface by the mobile terminal remote connection application according to the received data. Meanwhile, it is further required to determine whether menu is an active item in the linkage data set according to menu _ id.

If the mobile terminal is an active item, the display equipment is remotely connected with the application, the current menu value is set according to the menu _ id through an interface provided by a bottom layer audio/video module jar packet, and a topic is formed according to the return value of the interface to inform the mobile terminal whether the setting is successful or not, and the value is the value after the setting is successful. And then acquiring all menu values and flag through the interface, transmitting the values and flag to the mobile terminal for remote connection application, and screening menu item data required by the current interface by the mobile terminal to complete interface updating.

If the mobile terminal is not an active item, the display equipment is remotely connected with the application, the current menu value is set only through an interface provided by a bottom layer audio/video module jar packet according to menu _ id, and a topic is formed according to the return value of the interface to inform the mobile terminal whether the setting is successful or not, and the value is the value after the setting is successful.

Another display device-side flow diagram of the image quality adjustment method shown in fig. 5. All menu information is acquired when the user enters an image quality adjusting interface (including adjusting interfaces at all levels), and the current interface information is updated, so that the user can directly perform set value operation without performing get value operation when modifying a certain option.

Accordingly, the mobile terminal flow diagram of the image quality adjusting method shown in fig. 6 is shown. And the user operates the mobile terminal, and actively sends the topic of the getAllmenuInfo to the display device after entering a primary interface for adjusting the image quality of the mobile terminal. After receiving the topic of the allmenuInfo returned by the display device, the menu information of the current interface is updated. At this time, if the user clicks the relevant key of the mobile terminal to enter other secondary interfaces for adjusting the image quality, the topic of the getAllmenuinfo is retransmitted to the display device. After receiving the topic of the allmenuInfo returned by the display device, the menu information of the current interface is updated. And if no other secondary interface for adjusting the image quality is entered, clicking and modifying the value of a certain item in the current interface, and continuously sending the modified value of the certain item to the display device in a topic form.

The setting result of the display device can be continuously received, and according to whether the setting result of the display device is consistent with the setting result set on the mobile terminal or not, if so, the setting is successful, and if not, the setting is failed, and the setting operation is ended. And judging whether the menu is on the current interface, if so, updating the information of the menu, and if not, ending the setting operation.

In some embodiments, after receiving a setting result sent by the display device, it is further necessary to further determine whether the modification item is an active item, if the modification item is an active item, it is necessary to receive, from the display device, information of the active item after all other non-active items are changed, which is still in a topic form of receiving allmenuininfo, and finally, change the menu information on the current interface according to the obtained information.

step S61: when connection with external equipment through the WIFI module is detected, responding to a first control instruction sent by the external equipment, and sending image display parameter item information used for indicating image display quality to the external equipment so as to display the image display parameter item information on the external equipment;

For example, the mobile terminal includes a remote connection application, the display device includes a corresponding display device end remote connection application, and the mobile terminal may establish a connection with the display device through the remote connection application. Specifically, as shown in fig. 1E, the remote connection application page 41 of the mobile terminal may automatically detect whether the mobile terminal is connected to the display device after the user opens the remote connection application of the mobile terminal. If the display equipment is not connected, a prompt message dialog box pops up on a remote connection application interface of the mobile terminal: and if no equipment is connected, selecting the display equipment needing to be connected. And cancel and select options are displayed in the prompt message dialog. The user may press a select key directly on the mobile terminal causing the mobile terminal to jump from the remote connection application page 41 of FIG. 1E to the device list page 42 of FIG. 1F.

In connection with the method of fig. 7B, the method includes the steps of:

step S71: displaying a broadcast program on a display; for example, a broadcast program is displayed on the display in fig. 2D.

Step S72: when the fact that connection with external equipment is established through the WIFI module is detected, and when information of each image display parameter item used for indicating the image display quality on the displayer is displayed on the external equipment, responding to a second control instruction sent by the external equipment, and setting a parameter value of a first image display parameter item in each image display parameter item to be a second value from a first value;

For example, the user adjusts the value of the function item of the brightness function item on the mobile terminal from 50 of the brightness function item shown in fig. 1H to 70 shown in fig. 1I. The specific adjusting mode is as follows: the user drags the tip of progress bar behind the point touch progress bar, realizes the change of option numerical value, perhaps, directly the blank region of point touch numerical value scope strip for the tip direct movement of progress bar realizes the change of option numerical value to the position of point touch. At the same time, the brightness 50 of the image being played by the display in fig. 2D is adjusted to 70.

In connection with the method of fig. 7C, the method comprises the steps of:

step S81: displaying a broadcast program on a display; for example, a broadcast program is displayed on the display in fig. 2D.

Step S82: when the fact that connection with external equipment is established through the WIFI module is detected, and when information of each image display parameter item used for indicating the image display quality on the displayer is displayed on the external equipment, responding to a second control instruction sent by the external equipment, and setting a parameter value of a first image display parameter item in each image display parameter item to be a second value from a first value; the second control instruction at least comprises first image display parameter item information of which the parameter value sent by the external equipment is a second value;

step S83: displaying each image display parameter item information on the display while maintaining the display of the broadcast program in response to a third control instruction transmitted by the control means;

For example, the user adjusts the value of the function item of the brightness function item on the mobile terminal from 50 of the brightness function item shown in fig. 1H to 70 shown in fig. 1I. The specific adjusting mode is as follows: the user drags the tip of progress bar behind the point touch progress bar, realizes the change of option numerical value, perhaps, directly the blank region of point touch numerical value scope strip for the tip direct movement of progress bar realizes the change of option numerical value to the position of point touch. As shown in fig. 2B, in response to an instruction from the user to call up the image quality adjustment interface of the display device, while the broadcast program is kept being displayed, the image quality adjustment interface is displayed in the page, and at this time, the value of the brightness function item is 50. The brightness function item of the mobile terminal is adjusted from 50 shown in fig. 1H to 70 shown in fig. 1I, and the brightness function item of the image quality adjustment interface of the display device is also adjusted from 50 shown in fig. 2B to 70 shown in fig. 2C. Thus, whether the image quality adjustment is successful or not can be visually verified from the data.

In connection with the method of fig. 7D, the method includes the steps of:

step S91: displaying a broadcast program on a display;

step S92: when the fact that connection with external equipment is established through the WIFI module is detected, and when information of each image display parameter item used for indicating the image display quality on the displayer is displayed on the external equipment, responding to a second control instruction sent by the external equipment, and setting a parameter value of a first image display parameter item in each image display parameter item to be a second value from a first value; the second control instruction at least comprises first image display parameter item information of which the parameter value sent by the external equipment is a second value;

For example, the function items related to the image quality adjustment may include two types: an active term and a passive term. An active item herein refers to a functional item that is not dependent on other functional items. And a passive item is a functional item that is subordinate to other functional items. As shown in fig. 1K, the image quality adjustment interface of the mobile terminal includes a plurality of passive terms of contrast, brightness, color, sharpness, and image size. The active item image mode shown in fig. 1K takes on a value of "vivid", and the passive item takes on a value: contrast 60, brightness 45, color 65, color 0, sharpness 10, and image size are wide. The image of the display device at this time is displayed in a bright-colored manner according to the image mode value.

In connection with the method of fig. 7E, the method includes the steps of:

step S101: displaying a broadcast program on a display;

step S102: when the fact that connection with external equipment is established through the WIFI module is detected, and information of each image display parameter item used for indicating the image display quality on the displayer is displayed on the external equipment, responding to a second control instruction sent by the external equipment, and setting a parameter value of a first image display parameter passive item in each image display parameter item to be a second value from a first value; the second control instruction at least comprises first image display parameter item information of which the parameter value sent by the external equipment is a second value;

For example, the user may also adjust the value of the passive item individually, and change the contrast in the "standard" option in the image mode from 50 to 70, so that the mobile terminal automatically saves the contrast in the "standard" option in the image mode. If the user adjusts the image mode from 'bright-colored' to 'standard' of the image mode, the value taking situation of the passive item of the 'standard' of the image mode is changed as follows: contrast 70, brightness 50, color 60, color 0, sharpness 10, and image size are wide.

In the above embodiment, the display device establishes a connection with an external device through the WIFI module, for example, the mobile terminal establishes a connection with the display device, and sends each image display parameter item information for indicating image display quality to the mobile terminal, and the mobile terminal displays the image display parameter information. The image display parameter information on the display equipment is adjusted by adjusting the image display parameter information on the mobile terminal. Because the related function items are usually adjusted in a touch or drag mode on the mobile terminal, the operation is more convenient and faster, so that the scheme of the embodiment of the application can reduce the operation times of the user and improve the experience of the user in adjusting the image quality.
