In some embodiments of the present application, a user interface may be displayed in display 260. The user interface may be a specific target image, for example, various media materials obtained from a network signal source, including video, pictures and the like. The user interface may also be some UI interface of the display device, such as a system recommendation page or the like.

The display device may have various functions such as browsing web pages, playing media assets, entertainment games, video chat, etc., thereby providing a wide variety of services to users. The user may control the display device to launch a related application program to thereby launch a corresponding function.

In some embodiments, the controller 250 may control the display 260 to display a user interface when the user controls the display device to power on. FIG. 5 illustrates a schematic diagram of a user interface in some embodiments. As shown in fig. 5, the user interface includes a first navigation bar 500, a second navigation bar 510, a function bar 520, and a content display area 530, the function bar 520 including a plurality of function controls such as "watch record", "my collection", and "my application", etc. Wherein the content displayed in the content display area 530 will change as the selected controls in the first navigation bar 500 and the second navigation bar 510 change. When the application panel page is applied, a user can trigger entering a corresponding application panel by clicking on a My application control to input a display instruction for the application panel page. It should be noted that, the user may also input the selection operation of the function control in other manners to trigger entering into the application panel.

The user can view the application programs already installed on the display device, i.e., the functions supported by the display device, through the application panel. The user may select one of the applications and open it to implement the functionality of the application. It should be noted that, the application installed in the display device may be a system application or a third party application. And the user controls the display device to realize the corresponding function of the application program by starting the application program. Fig. 6 illustrates a schematic diagram of an application panel in some embodiments. As shown in fig. 6, the application panel includes three controls, namely a "player", "cable tv", and "game". Wherein the user can control the display device to open the player application by clicking on the "player" control. The user can perform corresponding operations in the player, such as searching for media assets, etc. The user may click on the "cable" control to view some of the media channels, including various media programs offered by the cable provider, using the display device. The user may click on the "game" control to play a game using the display device.

With the continuous improvement of the user's requirements on the quality of resources, the display device 200 currently provides the user with professional parameter setting functions in terms of resources Picture, sound, etc. Taking a picture display as an example, the display device may be provided with different image modes for different services of the display device. The image modes may include a movie mode, a game mode, a photo mode, etc., and picture parameters of each image mode may be different, and the picture parameters may include parameters of brightness, color temperature, contrast, backlight, etc. The user can control the display device to be in a different image mode so as to adjust the image quality of the display screen of the display device, thereby obtaining different visual effects.

In some embodiments, the user may actively select a certain image mode and set to the image mode in which the display device is currently operating. The user may input instructions to the display device to query for the image mode situation, such as by the system of the display device setting up a UI interface to select the relevant option of the image mode.

In response to the instruction of the user, the controller may first count all image modes supported in the display device and generate an image mode setting interface. The controller may control the display to display the image mode setting interface. FIG. 7 illustrates a schematic diagram of an image mode setting interface in some embodiments. As shown in fig. 7, the image mode setting interface includes a plurality of image mode controls, each image mode control corresponding to one image mode supported by the display device. The image modes in the display device may include a standard mode, a night mode, a movie mode, a game mode, a photo mode, and the like. The picture parameters corresponding to the standard mode are balanced, and taking the parameter range of 0-100 as an example, the picture parameters of the standard mode can be set to be 50. The night mode may protect the eyes of the user and may set picture parameters such as brightness to be low, e.g. 20. The movie mode, the game mode and the photo mode are image modes set according to the working content of the display device, and are respectively suitable for scenes of playing media assets, games and browsing pictures of the display device.

In some embodiments, each image mode may be set with respective default picture parameters, e.g., all picture parameters for standard mode may be set to 50. The user may also be set to adjust the picture parameters of each image mode by himself in view of the user experience. For example, when the user selects the standard mode, specific values of the parameters in the standard mode may also be set. FIG. 8 illustrates a schematic diagram of an image mode parameter adjustment interface in some embodiments. As shown in fig. 8, the current image mode of the display device is set to the standard mode, and the user can set various parameters of the standard mode, including brightness, color temperature, contrast, and backlight, for example, the user can adjust the brightness parameter to 45. The user may also click on a reply default settings control to control the display device to adjust all parameters of the image mode to default settings.

In some embodiments, the user may switch the working content of the display device when the user is using the display device, e.g., the display device is playing media assets, and may adjust the image mode of the display device to a movie mode. The user may control the display device to turn on the game function and turn off the playback of the asset. At this point, the display device may launch a game-related application. Since the display device is in the movie mode and is not suitable for the game scene, the display device may have a poor picture, and the user may switch the image mode of the display device to the game mode. The display device may also be provided with an image mode automatic switching function in consideration of the excessively complicated manual switching of the image mode by the user.

The display device can detect the current working scene and determine a proper image mode according to the working scene, so that the display device can be switched to the image mode by itself, and the viewing experience of a user is improved. The display device may be provided with an image mode automatic switching mode. When the display device enters the image mode automatic switching mode, the display device may turn on the image mode automatic switching function to switch the image mode.

In some embodiments, the user may send an image mode auto-switch mode instruction to the display device by operating a designated key of the remote control. The corresponding relation between the image mode automatic switching mode instruction and the remote controller key is bound in advance in the actual application process. For example, an image mode auto-switching mode button is provided on the remote controller, and when the user touches the button, the remote controller sends an image mode auto-switching mode command to the controller 250, and at this time, the controller 250 controls the display device to enter the image mode auto-switching mode. When the user touches the key again, the controller 250 may control the display device to exit the image mode auto-switching mode.

In some embodiments, the user may send an image mode auto-switching mode instruction to the display device by way of voice input using a sound collector of the display device, such as a microphone, to control the display device to enter an image mode auto-switching mode. The display device can be provided with an intelligent voice system, and the intelligent voice system can recognize the voice of the user so as to extract instruction content input by the user.

In some embodiments, the image mode automatic switching mode instruction may also be sent to the display device when the user controls the display device using the smart device, for example using a cell phone. In the actual application process, a control can be set in the mobile phone, whether to enter the image mode automatic switching mode can be selected through the control, so that an image mode automatic switching mode instruction is sent to the controller 250, and the controller 250 can control the display device to enter the image mode automatic switching mode.

An image mode automatic switching mode option may also be set in the UI interface of the display device, and when the user clicks the option, the display device may be controlled to enter or exit the image mode automatic switching mode.

In some embodiments, to prevent the user from false triggering the image mode automatic switching mode, when the controller 250 receives the image mode automatic switching mode instruction, the display 260 may be controlled to display image mode automatic switching mode confirmation information, so that the user performs a secondary confirmation as to whether to control the display device to enter the image mode automatic switching mode. Fig. 9 is a schematic diagram illustrating image mode automatic switching mode confirmation information in some embodiments.

In some embodiments, the controller may detect the operational scenario of the display device in real time. When a change in a work scene is detected, the controller may acquire a new work scene and determine a corresponding image mode of the scene. For example, when the user instructs to turn off the playback of the asset and turn on the game function during the playback of the asset by the display device, the controller may adjust the image mode of the display device to the game mode.

In some embodiments, the user may view the assets using the display device, including the assets stored locally on the display device and various assets in the network. The requirements for picture parameters may be different for each network asset, subject to the influence of the asset patch source. For example, the film source type may correspond to IMAX or dolby, whose corresponding picture parameters are different, and if only the default movie mode is used to display media, the use experience for the user may be poor. Thus, for different source types, corresponding image modes, such as dolby mode and IMAX mode, can also be set in the display device, respectively.

When the user instructs the display device to play the asset, the controller may detect whether the asset is a local asset or a network asset. If the media asset is local media asset, the controller can adjust the image mode of the display device to be a film mode. If the network resource is the network resource, the controller can acquire the film source information corresponding to the network resource so as to determine the type of the network resource. Taking the dolby type media asset provided by the film source as an example, the controller can adjust the image mode of the display device to the dolby mode so as to adapt to the picture display requirement of the network media asset and improve the viewing experience of a user.

In some embodiments, the display device is further provided with an external device interface, and the external device interface is used for connecting with an external device, so that the display device is connected with the external device, and the external device can be a game device. The display equipment and the external equipment which establish communication connection are respectively used as a receiving end (Sink end) and a transmitting end (source end), and the external equipment can perform a data transmission process through an external device interface and the display equipment and transmit media information signals to the display equipment. For example, in the course of using the game device by the user, it is possible to output video data and audio data in real time for the game process and transmit the video data and audio data to the display device to output the video data and audio data as image pictures and sounds through the display device. At this time, the game device serves as a transmitting end, and the display device serves as a receiving end.

The display device and the external device are provided with data interfaces with the same interface specification and function. As shown in fig. 10, HDMI (High Definition Multimedia Interface, high-definition multimedia interface) is provided on both the display device and the external device. In the use process, a user can insert two ends of the HDMI interface data line on the display device and the external device respectively, and after the external device and the display device are started, the signal source of the display device is set to be an HDMI interface, so that data transmission between the display device and the external device is realized.

In order to realize communication connection between the display device and the external device, other connection modes, such as DVI (Digital Visual Interface), VGA (Video Graphics Array), USB (Universal Serial Bus) and the like, can be adopted between the display device and the external device; and can also be wireless connection modes, such as wireless local area network, bluetooth connection, infrared connection and the like. Different communication connection modes can adopt different information transfer protocols, for example, when the connection is realized by adopting an HDMI interface, the HDMI transmission protocol can be adopted for data transmission.

It should be noted that the media signal sent by the external device to the display device may include signals in multiple formats, where some signals in special formats may exist, such as filemmaker (movie producer), HDR (High Dynamic Range ), HDR10+, DOLBY, ALLM (Auto Low-latency Mode), SPD (Specific Product Description ), IMAX, and the like. These special format signals have special requirements for image display, such as parameters like image quality, contrast, brightness etc. If the content of the signals is only displayed by using a general film mode in the display device, the image mode cannot adapt to the display requirement of the signals, so that the picture effect is poor, and the use experience of users is seriously affected. Therefore, when the display device is connected with the external device, the controller can detect the special signals so as to set the image mode of the display device and improve the watching experience of the user.

FIG. 11 illustrates an interactive flow diagram of components of a display device in some embodiments, including the steps of:

s101, responding to a media information signal sent by an external device, and acquiring the signal type of the media information signal.

S102, acquiring signal format information of the media information based on the detected signal type being a preset type.

S103, setting the image mode of the display device to be a target image mode based on the detected signal format information including the target signal format. Based on detecting that the target signal format is not included in the signal format information, a history image mode is acquired based on a preset user image mode database, and the image mode of the display device is set to the history image mode.

S104, analyzing the media information into media information images, and controlling a display to display the media information images.

The user may select a signal type of a particular format by himself, which in the present embodiment is referred to as the target signal format. The target signal format can be set as a filemmaker, and the filemmaker is used for enabling the display device to conduct specific detection, so that when the external device sends the type of signal, the display device can be switched to an image mode corresponding to the type of the model, and the use experience of a user is improved.

In some embodiments, after detecting that the display device is connected to the external device, the controller may detect whether the external device sends a media asset signal to the display device.

If the external device is detected to send the media information to the display device, the controller can acquire the signal type of the media information, and the model type can comprise HDMI, USB and the like. The controller may detect whether the signal type and the model type corresponding to the target signal format are the same to determine whether the target signal format can be included in the media signal. Taking the target signal format as a filemmaker as an example, the external device can input the filemmaker signal to the display device through the HDMI, so that the model type corresponding to the target signal format is the HDMI signal, and the HDMI can be determined to be a preset type.

The controller may detect whether the signal type of the media asset signal is HDMI. When the signal type is HDMI, the media signal may include a target signal format, and the controller may continuously detect whether the target signal format exists in the media signal.

In some embodiments, the controller may detect whether the video signal is included in the media asset signal before acquiring the signal type of the media asset signal to determine whether the current media asset signal has a need to switch image modes.

The media data signal may include only a video signal, may include only an audio signal, and may include both a video signal and an audio signal.

In the case that the media information signal does not contain the video signal, the display device does not need to switch the image mode because the display picture is not needed, and the controller only needs to process the audio signal. The controller may parse the audio signal to obtain audio data. An audio output interface may also be provided in the display device, through which the display device may be connected to an audio device, such as a loudspeaker. An audio device, such as a speaker, may also be built into the display device. The controller may control the audio device to play audio data.

For the case that the media asset signal includes a video signal, it is explained that the media asset signal may require the display device to switch the image mode, at which time the controller may acquire the signal type of the video signal.

In some embodiments, the controller may obtain signal format information of the media asset signal, where the signal format information is used to characterize a signal format condition contained in the media asset signal. The controller may control the external device interface to detect a signal format included in the media asset signal.

It should be noted that the media information signal sent by the external device may include the target signal format, may not include the target signal format, and may also include other special signal formats, such as ALLM, SPD, IMAX, HDR, HDR10+ and dolby. The requirements for the display of the picture are different for each particular signal format, as are the visual effects presented to the user. The requirements for picture parameters are more complex and more influential for the user's viewing than filemmaker, ALLM, SPD, IMAX, HDR + and dolby, so that the priority of these special signal formats can be set to be higher than the target signal format. That is, when these special formats and the target signal formats coexist, the image mode of the display device may be preferentially set to the image mode corresponding to these special signal formats.

The degree of influence on the user's viewing is also different for these particular signal formats. Thus, these special signal formats may be prioritized as well. In this embodiment, the special signal formats are set to two priorities, which are respectively referred to as a first type signal format and a second type signal format, where the priority of the first type signal format is greater than that of the second type signal format. The first type of signal format and the second type of signal format may be set by a technician designing the display device.

In some embodiments, the first type of signal format and the second type of signal format may also be determined based on a degree of gap between the particular signal format and the target signal format. The picture parameter conditions of the image modes corresponding to each special signal format and the target signal format can be counted first, and the difference between the picture parameter of the image mode corresponding to each special signal format and the picture parameter of the image mode corresponding to the target signal format can be obtained respectively. The number of the most distant special signal formats is determined as a first type of signal format, and the remaining special signal formats are determined as a second type of signal format.

In the embodiment of the application, ALLM, SPD, IMAX is used as a first type signal format, and HDR10+ and dolby are used as a second type signal format for analysis.

It should be noted that, for the special signal format HDR, the priority of HDR and filemmaker may be set to be the same, that is, the HDR need not be detected when the first type signal format and the second type signal format are detected. If the first type signal format and the second type signal format do not exist in the media data signal, the controller can detect whether a signal in the HDR format exists. For the HDR format, the display device may be provided with an HDR image mode. The HDR image mode can comprise an HDR image mode, and the image mode can be compatible with the HDR image mode and the filemmaker image mode, so that the requirement of an HDR signal format is met, and the requirement of the filemmaker signal format is met. Thus, if both HDR and filemmaker are detected, the controller may set the image mode of the display device to HDR.

In some embodiments, the controller may obtain first type signal format status information based on the media asset signal, where the first type signal format status information is used to characterize whether the media asset signal includes the first type signal format.

The controller may obtain a first flag bit status value corresponding to a first type of signal format in the media asset signal based on the external device interface. The external device interface itself may detect the signal format in the media asset signal, so the controller may control the external device interface to detect whether the media asset signal includes the first type of signal format. The external device interface may set the first flag bit state value corresponding to the first type signal format to 1 if the first type signal format is included, and may set the first flag bit state value corresponding to the first type signal format to 0 if the first type signal format is not included.

In some embodiments, the external device may first determine whether the media signal includes a first type of signal format, generate a first flag bit state value of 1 if the media signal includes the first type of signal format, and generate a first flag bit state value of 0 if the media signal does not include the first type of signal format. The external device may send the first flag bit status value and the media asset signal to the display device together.

The controller may determine whether the media signal includes a first type of signal format according to the first flag bit status value.

If the status value of the first flag bit is 0, determining that the media information does not contain the first type signal format; if the status value of the first flag bit is 1, the media information signal is determined to contain a first type of signal format.

In some embodiments, if the media asset signal includes a first type of signal format, the controller may set the image mode of the display device to an image mode corresponding to the first type of signal format. For example, if the media information includes an IMAX signal format, the controller may directly set the image mode of the display device to the IMAX image mode.

If the media asset information does not contain the first type of signal format, the controller can continuously detect whether the media asset signal contains the target signal format, and the controller can acquire the target signal format state information based on the media asset signal, wherein the target signal format state information is used for representing whether the media asset signal contains the target signal format.

In some embodiments, when acquiring the status information of the target signal format, the controller may acquire a second flag bit status value corresponding to the target signal format in the media asset signal based on the external device interface. If the second flag bit state value is 0, it may be determined that the media asset information does not include the target signal format. If the status value of the second flag bit is 1, it may be determined that the media information signal includes the target signal format.

The external device interface can automatically detect whether the media information signal contains the target signal format, so as to generate a second flag bit state value. Or the external device can pre-determine whether the target signal format is contained, so as to generate a second zone bit state value and send the second zone bit state value to the display device.

In some embodiments, based on detecting that the signal format information includes the target signal format, for example, the second flag bit state value is 1, the controller may set the image mode of the display device to an image mode corresponding to the target signal format, which is referred to as a target image mode in this embodiment. At this time, the picture parameters in the display device can meet the display requirement of the target signal format, thereby improving the viewing experience of the user.

Based on detecting that the target signal format is not included in the signal format information, for example, the second flag bit state value is 0, the controller may keep the image mode of the display device to be the image mode set last by the user. The controller may acquire a history image mode based on a preset user image mode database and set the image mode of the display device to the history image mode.

The display device is provided with a user image pattern database in advance. When the user controls the display device to be in a certain image mode by himself, the controller may store the image mode in the user image mode database as a history image mode. The controller may update the historical image pattern in the user image pattern database to the image pattern newly selected by the user if the user changes the image pattern of the display device.

In some embodiments, a target signal format detection switch may be provided in the display device, which may control whether the display device is capable of automatically entering the target image mode. The controller allows the display device to enter the target image mode when the target signal format detection switch is in an on state, and does not allow the display device to enter the target image mode if the target signal format detection switch is in an off state.

After the controller detects that the signal format information includes the target signal format, for example, the status value of the second flag bit is 1, the status information of the target signal format detection switch in the display device can be obtained.

The controller may set the image mode of the display device to the target image mode if the target signal format detection switch is in an on state.

If the target signal format detection switch is in an off state, the controller may maintain the image mode of the display device as the image mode set last by the user since the display device is not allowed to enter the target image mode. That is, when the target signal format detection switch is in an off state, the controller may acquire a history image mode based on a preset user image mode database and set the image mode of the display device to the history image mode.

In some embodiments, the controller may also detect whether the media asset signal includes the second type signal format before adjusting the image mode of the display device to the target image mode, considering that the second type signal format has a higher priority than the target signal format.

After detecting that the target signal format detection switch is in an on state, the controller can acquire state information of a second type of signal format in the media information based on the external device interface, and the state information is used for representing whether the media information contains the second type of signal format.

If the media asset signal contains the second type signal format, the controller may set the image mode of the display device to the image mode corresponding to the second type signal format. For example, the media asset signal contains dolby format, the controller sets the image mode of the display device to dolby mode.

The controller may set the image mode of the display device to the target image mode if the medium information signal does not include the second type signal format.

In some embodiments, considering that the user may not know the state of the target signal format detection switch, the display device may not enter the target image mode when the target signal format detection switch is in the off state, and if the media information signal includes the target signal format, the viewing experience of the user may be affected, so when the target signal format detection switch is detected to be in the off state, the controller may control the display to display the target signal format prompting interface. FIG. 12 illustrates a schematic diagram of a target signal format hint interface in some embodiments. As shown in fig. 12, the target signal format prompt interface includes prompt information, a confirmation control and a cancel control. The prompt information is used for prompting whether to turn on the target signal format detection switch, and may be that the target signal format detection switch is in a current off state, the display device cannot enter the target image mode, and whether to turn on the target signal format detection switch is requested to be confirmed.

In response to a user's selection of the cancel control, the controller may acquire a history image mode based on a preset user image mode database and set an image mode of the display device to the history image mode.

In response to a user's selection of the confirmation control, the controller may set the target signal format detection switch to an on state and set the image mode of the display device to a target image mode.

In some embodiments, after controlling the display device to enter a certain image mode, the controller may parse the media asset signal to obtain a media asset image, and control the display to display the media asset image.

After detecting that the external device stops sending the media asset signal, the controller can set the target signal format detection switch to be in a closed state. Meanwhile, the controller may set the image mode of the display device to the history image mode set last by the user, for example, acquire the history image mode stored in the user image mode database, and switch the image mode from the target image mode to the history image mode.

In some embodiments, the user may also switch other image modes by himself while the display device is in the target image mode. The user may input an instruction to query the image mode to call up the image mode setting interface of the switchable image mode.

In response to a user selection operation of the target image mode control, the controller may set an image mode of the display device to an image mode corresponding to the target image mode control, which is referred to as a first image mode in the embodiment of the present application, and simultaneously the controller may store the first image mode in the user image mode database, so that a history image mode in the user image mode database is updated to the first image mode.

The embodiment of the application also provides an image mode setting method, which comprises the following steps:

step 1301, responding to a media information signal sent by an external device, and obtaining a signal type of the media information signal.

Step 1302, based on detecting that the signal type is a preset type, obtaining signal format information of the media asset signal.
