[0068] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0070] The terms "first" and "second" in this disclosure are used to distinguish different objects rather than to describe a specific order of objects. For example, a first processing result and a second processing result are used to distinguish different processing results rather than to describe a specific order of processing results.

[0071] The external device mainly refers to a device that can be connected to the display device to achieve the purpose of surfing the Internet, watching online TV programs or playing digital video discs. Generally, the external device can be a set-top box, a DVD, and network boxes of various brands. The specific type of the external device is not limited in the embodiments of the present disclosure. Through the interaction between the external device and the display device, the user can have a richer experience.

[0072] Currently, display devices of various brands generally support the key transmission function of Consumer Electronics Control (CEC). Through this key transmission function, the key information received by the display device can be transparently transmitted to the external device, so as to achieve the function of controlling the corresponding keys of the external device, such as controlling the play, pause, up, down, left, right and other keys of the external device.

[0073] Figure 1A FIG. 1 is a schematic diagram of an operation scenario among a display device, an external device, and a control device according to one or more embodiments of the present disclosure. Figure 1A As shown, the external device 201 is connected to the display device 200, and the user can watch the content in the external device 201 through the display device 200. The external device 201 can be controlled using the control device (such as a remote controller) 100 of the display device.

[0074] Figure 1B FIG. 1 is a schematic diagram of a key control method in the prior art. Figure 1B As shown, the display device detects that an external device is connected, and the channel of the display device is a High Definition Multimedia Interface (HDMI) channel to which the external device is connected. When the display device receives a key command sent by a control device of the display device, it directly forwards the key command to the external device, which processes the key command. This method may cause the display device buttons to fail.

[0075] Another key control method is: the display device detects that an external device is connected, and the channel of the display device is the HDMI channel to which the external device is connected. When the display device receives a key command sent by the control device of the display device, both the display device and the external device will process the key command. At this time, the information after both devices process the key command is displayed on the page of the display device. Occlusion problems may occur, resulting in incomplete information display.

[0076] For example, Figure 1C FIG. 1 is a schematic diagram of an interface display when another key control method in the prior art has an occlusion problem. Figure 1CAs shown in the figure: when external device A is connected to the display device, and the channel of the display device is the HDMI channel connected to the external device A, the display of the display device displays the screen of the external device. When the display device and the external device both process the received key command, the first processing result after the display device processes the key command is: XXXX; the second processing result after the external device A processes the key command is: XX page, from Figure 1C It can be seen that when the first processing result and the second processing result are displayed at the same time, an occlusion problem occurs, resulting in incomplete information display, thereby affecting the user experience.

[0077] In order to solve the above problems, an embodiment of the present disclosure proposes a key control method, first, the controller of the display device detects that an external device is connected, and sets the channel of the display device to the HDMI channel to which the external device is connected, then the controller receives a key instruction for a first key sent by the control device of the display device, and controls the display of the display device to pop up a target page, wherein the target page includes prompt information, and the prompt information is used to instruct the user to select a target device for processing the key instruction from the external device and the display device, and finally the controller responds to the operation of selecting the target device and controls the display to display the corresponding processing result after the target device processes the key instruction. In the above technical scheme, the target device for processing the key instruction is determined by the user, so that the key functions of the external device and the display device can be taken into account, the user's operation can be met, the problem of key failure or obstruction can be avoided, and the user experience is improved.

[0079] In some embodiments, a mobile terminal, a tablet computer, a computer, a laptop computer, and other smart devices may also be used to control the display device 200 .

[0080] In some embodiments, the display device 200 may not use the above-mentioned smart device or control device to receive instructions, but may receive user control through touch or gestures.

[0081] In some embodiments, the display device 200 can also be controlled in ways other than control devices and smart devices. For example, the user's voice command control can be directly received through a module for obtaining voice commands configured inside the display device 200, or the user's voice command control can be received through a voice control device set outside the display device 200.

[0082] In some embodiments, the mobile terminal can install software applications with the display device 200, and realize connection communication through the network communication protocol to achieve the purpose of one-to-one control operation and data communication. The audio and video content displayed on the mobile terminal can also be transmitted to the display device 200 to realize the synchronous display function. The display device 200 can also communicate data with the server through a variety of communication methods, allowing the display device 200 to communicate and connect through a local area network (LAN), a wireless local area network (WLAN) and other networks. The server can be a cluster or multiple clusters, and can include one or more types of servers. The server can provide various content and interactions to the display device 200. The display device 200 can be a liquid crystal display, an OLED display or a projection display device. In addition to providing a broadcast receiving television function, the display device 200 can also provide an intelligent network TV function that provides a computer support function.

Finally, in response to the operation of selecting the target device, the controller controls the display to display the corresponding processing result after the target device processes the key instruction. In the above technical scheme, the target device for processing the key instruction is determined by the user, and the key functions of the external device and the display device can be taken into account to meet the user's operation, avoid the problem of key failure or occlusion, and improve the user experience. In order to explain this scheme in more detail, the following will be combined in an exemplary manner. Figure 5A To explain, it is understandable that Figure 5A The steps involved may include more steps or fewer steps in actual implementation, and the order of these steps may also be different, subject to the key control method provided in the embodiment of the present disclosure being implemented, and the embodiment of the present disclosure is not limited thereto.

[0119] Figure 5A A flowchart of a key control method provided by an embodiment of the present disclosure is shown in FIG. Figure 5B The schematic diagram of the principle of a key control method provided by an embodiment of the present disclosure is shown in FIG. This embodiment is applicable to the case where a display device processes a key command when receiving a key command sent by a control device. Figure 5A As shown, the key control method specifically includes the following steps:

[0120] S510: Detecting that an external device is connected, setting a channel of the display device to an HDMI channel to which the external device is connected.

[0121] Among them, the external device mainly refers to a device that can be connected to a display device to achieve the purpose of surfing the Internet, watching online TV programs or playing digital video discs. Generally, the external device can be a set-top box, a DVD, and network boxes of various brands, etc. The specific type of the external device is not limited in the embodiments of the present disclosure. HDMI is a fully digital video and sound transmission interface that can send uncompressed audio and video signals. HDMI can be used for set-top boxes, DVD players, personal computers, TVs, game consoles, integrated amplifiers, digital audio and TVs, etc.

[0122] Specifically, when an external device is connected to the display device, the controller of the display device can detect that the display device is currently connected to the external device, and set the channel of the display device to the HDMI channel to which the external device is connected. At this time, the picture displayed on the display of the display device is the picture of the external device.

[0123] S520, receiving a key instruction for a first key sent by a control device of the display device, controlling the display of the display device to pop up a target page, wherein the target page includes prompt information, and the prompt information is used to instruct the user to select a target device for processing the key instruction from an external device and a display device.

[0124] Among them, the control device of the display device can be understood as a remote control corresponding to the display device or other devices that can control the display device through the CEC function. The target page can be understood as an interactive (Dialog) page with prompt information. The first button can be understood as a button that can be processed by both the external device and the display device. The first button is a button included in the control device of the display device, for example, an INFO (Information) button, a PICTURE (Image Setting) button or a SOUND (Sound Setting) button, etc. This embodiment does not specifically limit the first button.

[0125] Specifically, when the user wants to control the display device or the external device, the purpose can be achieved by operating the control device of the display device. Therefore, when the user presses the first button included in the control device of the display device, the controller of the display device can receive the key command for the first button sent by the control device of the display device, and control the display of the display device to pop up the target page, which includes prompt information. Through the prompt information, the user can be instructed to select the target device for processing the key command from the external device and the display device, thereby giving the user sufficient prompts and selection rights, allowing the user to independently choose whether the key command is processed by the display device, or forwarded to the external device for processing by the external device, so as to avoid the failure of the display device button due to the processing by the external device, or the occlusion problem caused by the simultaneous processing of the external device and the display device.

[0126] S530, in response to the operation of selecting the target device, controlling the display to display the corresponding processing result after the target device processes the key instruction.

[0127] Specifically, the user can select a target device for processing key commands from external devices and display devices by operating the control device or voice control according to the prompt information in the target page. After the user selects the target device, the key commands are processed by the target device accordingly. Then, the controller of the display device responds to the user's operation of selecting the target device and can control the display to display the corresponding processing results after the target device processes the key commands.

[0128] For example, Figure 5C A schematic diagram of a target page provided by an embodiment of the present disclosure. Figure 5C As shown, external device A is connected to the display device, and the prompt information in the target page is: Both external device A and the display device will process key commands, please select the target device that processes key commands. There are two options below the prompt information: external device A and display device. Through this target page, the user can be prompted to select the target device that processes key commands from the external device and the display device, avoiding the problem in the prior art that the key commands are processed by the external device, which may cause the display device key to fail, or the occlusion problem that occurs when the display device and the external device jointly process the key commands.

[0129] In some embodiments, the detecting that an external device is connected and setting the channel of the display device to a high-definition multimedia interface HDMI channel connected to the external device may specifically include:

[0130] It is detected that the external device is connected, it is determined that the external device is in a powered-on state, and in response to a trigger operation of the second button by the user, the channel of the display device is set to the HDMI channel to which the external device is connected.

[0131] The second button may be an INPUT button.

[0132] Specifically, the controller of the display device detects that an external device is connected and determines that the external device is in a powered-on state. The user triggers a second button in the control device to call out the second button. Accordingly, the controller of the display device responds to the user's triggering operation on the second button and can directly select the HDMI channel to which the external device is connected, that is, the channel of the display device is set to the HDMI channel to which the external device is connected.

[0133] In this embodiment, the channel of the display device is set as the HDMI channel to which the external device is connected by the above method, which is simple and convenient and is conducive to the smooth progress of subsequent processes.

[0134] In some embodiments, the detecting that an external device is connected and setting the channel of the display device to a high-definition multimedia interface HDMI channel connected to the external device may further specifically include:

[0135] Detecting that the external device is connected, determining that the external device is switched from a power-off state to a power-on state, and obtaining an HDMI channel to which the external device is connected;

[0136] A channel jump instruction sent by the external device is received, and according to the channel jump instruction, a channel of the display device is set to be an HDMI channel to which the external device is connected.

[0137] Specifically, if the external device is in the off state, when the external device is connected to the display device, the user turns on the external device. Accordingly, the controller of the display device can obtain the HDMI channel connected to the external device after detecting the connection of the external device and determining that the external device is switched from the off state to the on state. At the same time, after the external device is in the on state, it can also obtain the HDMI channel connected to itself by reading the physical address reported by the extended display identification data (EDID). The external device sends a channel jump instruction to the display device, and then the controller of the display device can receive the channel jump instruction sent by the external device, and according to the channel jump instruction, set the channel of the display device to the HDMI channel connected to the external device.

[0138] In this embodiment, by receiving a channel jump instruction sent by an external device and according to the channel jump instruction, the channel of the display device can be set to the HDMI channel to which the external device is connected. This is another channel setting method, which can expand the channel setting method and ensure that various situations are covered, which is conducive to the smooth progress of subsequent processes.

[0139] In some embodiments, setting the channel of the display device to a high-definition multimedia interface HDMI channel to which the external device is connected may further specifically include:

[0140] The connection of the external device is detected, the HDMI channel to which the external device is connected is determined through the TV input framework TIF provided by the operating system of the display device, and the channel of the display device is set to the HDMI channel to which the external device is connected.

[0141] Among them, TV Input Framework (TIF) is a set of standard application programming interfaces (Application Program Interface, API) provided by Android system for TV (TV) manufacturers. TIF is mainly used to create TvInput module to control TV with Android system, and provide system signal source management. The corresponding system service is TvInputManagerService (TV input management service). HDMITvInputService (High Definition Multimedia Interface TV Input Management Service) is a signal control service for controlling HDMI channels provided by TV manufacturers. It can provide identification registration, creation, control and destruction of HDMI channels, etc. It starts running after the TV system is started. The operating system of the display device can be Android system.

[0142] Correspondingly, after the external device is connected to the display device, the display device automatically turns on the CEC Control function by default. If the CEC function is not turned on, you can set CEC Control to on and TV autopower on to on in Settings. At the same time, the external device is connected to the display device via an HDMI cable. When TV auto power on is set to on, HDMI is connected to the signal source (external device, such as DVD), and the signal source and display device are both turned off. When the signal source is turned on, the display device automatically turns on and switches to the HDMI channel.

[0143] Therefore, when the controller of the display device detects that an external device is connected, the HDMI channel to which the external device is connected can be determined through the TIF provided by the operating system of the display device, and the channel of the display device can be directly set to the HDMI channel to which the external device is connected.

[0144] In this example, the channel of the display device is set by the above channel setting method, which is efficient and fast, and is conducive to the smooth progress of subsequent processes.

[0145] In some embodiments, the physical channels of the display device in the TIF may include Tuner (Tv channel, i.e., the channel connected to the signal line of the display device), HDMI channel, and Composite channel (AV channel, i.e., the channel connected to the yellow, white, and red lines), etc. Each channel corresponds to a unique string inputId (input identifier) ​​as the unique identifier of the channel. Among them, the HDMI channel is special. When an external device (such as a DVD, a box, etc.) is inserted into the HDMI port, the external device will be added to the channel list as a sub-channel (i.e., the external device name, CEC Name), and after the external device is inserted into the HDMI port, the Android system will receive a notification from the underlying hardware, and the external device will be automatically added to the channel list. At the same time, the sub-channel will disappear after the external device is unplugged to avoid being displayed all the time.

[0146] Fig. 6A A flowchart of another key control method provided by an embodiment of the present disclosure is shown in FIG. Figure 6B The schematic diagram of another key control method provided by the embodiment of the present disclosure is a principle diagram. This embodiment is optimized on the basis of the above embodiment. Optionally, this embodiment can be applied to the process of controlling the display to display the corresponding processing result after the target device processes the key command when the target device is a display device and an external device respectively. Fig. 6A As shown, the key control method specifically includes the following steps:

[0147] S610: Detecting that an external device is connected, setting a channel of the display device to an HDMI channel to which the external device is connected.

[0148] S620, receiving a key instruction for a first key sent by a control device of the display device, controlling the display of the display device to pop up a target page, wherein the target page includes prompt information, and the prompt information is used to instruct the user to select a target device for processing the key instruction from an external device and a display device.

[0149] S630: Determine whether the target device is a display device.

[0150] If yes, execute S640; if no, execute S650-S660.

[0151] Specifically, the user can select a target device for processing key commands from external devices and display devices by operating the control device or voice control according to the prompt information in the target page. After the user selects the target device, the controller of the display device needs to determine whether the target device is a display device.

[0152] S640, in response to the operation of selecting the target device, controlling the display to display a first processing result corresponding to the key instruction processed by the display device.

[0153] Specifically, if the target device is a display device, the key instruction is processed by the display device. Accordingly, the controller of the display device directly controls the display to display a first processing result corresponding to the key instruction processed by the display device in response to the operation of selecting the target device.

[0154] Exemplarily, if the first button is an INFO button, after receiving a button instruction for the INFO button, the display device will respond to the button instruction and control the display to display the channel information of the HDMI channel of the display device.

[0155] For example, Figure 6C This is a schematic diagram of a page of the first processing result provided by an embodiment of the present disclosure. Figure 6C As shown, the external device A is connected to the display device, and the display of the display device displays: when the target device is the display device, the first processing result corresponding to the key instruction processed by the display device: XX information.

[0156] S650: In response to the operation of selecting the target device, the key instruction is sent to the external device.

[0157] Specifically, if the target device is an external device, the key instruction is processed by the external device. Accordingly, the controller of the display device sends the key instruction to the external device in response to the operation of selecting the target device, so that the external device can process the key instruction after receiving the key instruction.

[0158] S660, controlling the display to display a second processing result corresponding to the key instruction processed by the external device.

[0159] After receiving the key command, the external device processes the key command, and accordingly, the controller of the display device controls the display of the display device to display the second processing result corresponding to the key command processed by the external device.

[0160] Exemplarily, if the first button is an INFO button, after receiving the button instruction for the INFO button, the display device will send the button instruction to the external device. After the external device responds to the button instruction, it will control the display to display the information of the external device.

[0161] For example, Fig.6D This is a schematic diagram of a page of a second processing result provided by an embodiment of the present disclosure. Fig.6D As shown, the external device A is connected to the display device, and the display of the display device displays: when the target device is the external device A, the second processing result corresponding to the key instruction processed by the external device: XX page.

[0162] In this embodiment, the controller of the display device first detects that an external device is connected, sets the channel of the display device to the HDMI channel to which the external device is connected, then receives a key instruction for a first key sent by the control device of the display device, controls the display of the display device to pop up a target page, and the target page includes prompt information, the prompt information is used to instruct the user to select a target device for processing the key instruction from the external device and the display device, and then determines whether the target device is a display device. If the target device is a display device, then in response to the operation of selecting the target device, the display is controlled to display a first processing result corresponding to the display device processing the key instruction; if the target device is an external device, then in response to the operation of selecting the target device, the key instruction is sent to the external device, and the display is controlled to display a second processing result corresponding to the external device processing the key instruction. In the above scheme, the target device is selected through the user's operation, and when the target devices are the display device and the external device respectively, the display displays the corresponding processing result after the target device processes the key instruction. This is not only comprehensive, but also can take into account the key functions of the external device and the display device, meet the user's operation, avoid the problem of key failure or obstruction, and is conducive to improving the user's usage experience and satisfaction.

[0163] In some embodiments, the target device is an external device; in response to the operation of selecting the target device, sending the key instruction to the external device may specifically include:

[0164] In response to the operation of selecting the target device, the HDMI control service of the display device is called, and the key instruction is sent to the external device.

[0165] Specifically, after the HDMITvInputService service is started, the underlying hardware device will report the physical channel information through onHardwareAdded or onHdmiDeviceAdded. HDMIControlService (HDMI control service) is a service of the Android system, which is responsible for CEC-related functions and is also started when the display device is started. After the external device is connected to the display device, HDMITvInputService will receive the HDMI channel information reported by onHdmiDeviceAdded. If the external device supports the CEC function, the HDMIControlService is obtained through HDMITvClinet. At this time, the key instructions received by the display device can be sent to the external device through HDMIControlService. Therefore, when the target device is an external device, the controller of the display device responds to the operation of selecting the target device, and can send the key instructions to the external device by calling the HDMI control service (HDMIControlService) of the display device, so that the external device can process the key instructions after receiving the key instructions.

[0166] In this embodiment, the key command is sent to the external device by the above method, which is simple, efficient and fast, and is conducive to the smooth progress of the subsequent process.

[0167] In summary, the present disclosure executes the above-mentioned key control method on a display device. First, the controller of the display device detects that an external device is connected, and sets the channel of the display device to the HDMI channel to which the external device is connected. Then, the controller receives a key instruction for a first key sent by the control device of the display device, and controls the display of the display device to pop up a target page. The target page includes prompt information, and the prompt information is used to instruct the user to select a target device for processing the key instruction from the external device and the display device. Finally, the controller responds to the operation of selecting the target device and controls the display to display the corresponding processing result after the target device processes the key instruction. In the above-mentioned technical scheme, the target device for processing the key instruction is determined by the user, so that the key functions of the external device and the display device can be taken into account, the user's operation can be met, the key failure or obstruction problem can be avoided, and the user experience is improved.
