Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart of a processing method disclosed in an embodiment of the present application, and the processing method shown in fig. 1 is applicable to an output device capable of outputting image data and capable of outputting audio data by connecting an active audio device. Referring to fig. 1, the processing method may include the steps of:
step 101: transmitting first attribute information to an electronic device, wherein the first attribute information comprises display parameter information.
The first attribute information may be information that is transmitted by the output device to the electronic device after the electronic device and the output device are connected, and is used for characterizing the relevant output configuration of the output device. In the embodiment of the present application, the first attribute information may include, but is not limited to, display parameter information, for example, the first attribute information may also include configuration information related to audio output. In one implementation, the first attribute information may be EDID (Extended display identification data) of the output device.
Step 102: first image data sent by the electronic equipment in a first audio mode is obtained and output. The first image data is determined by the electronic equipment at least according to the display parameter information, and the first audio mode is a mode of not transmitting audio data.
After receiving the first attribute information, the electronic device processes first image data for display output on an output device based on display parameter information therein. Meanwhile, the first attribute information can also enable the electronic equipment to process the audio data needing to be output based on the first audio mode. In the case that the first attribute information is EDID, the status parameter of the EDID regarding the audio function may be off, that is, indicate that the output device is not capable of audio output.
The first audio mode is a mode in which audio data is not transmitted, that is, in the first audio mode, the electronic device does not transmit the audio data to the output device for audio output, but controls the audio data to be output on the electronic device side.
Under the mode of not transmitting audio data, the electronic equipment cannot transmit the audio data to the output equipment, and the output equipment cannot transmit the acquired audio data acquired by the output equipment to the electronic equipment. For example. The output device does not transmit the sound data collected by the microphone to the electronic device for output even if the microphone is connected.
Step 103: in the process of outputting the first image data, connection information of an audio device is detected.
In the process that the electronic device outputs the first image data through the output device, the output device can detect the connection information of the audio device of the output device in real time, and the audio device can be an earphone device, an external loudspeaker device and the like.
It can be understood that, when a user uses a display externally connected to the notebook computer to output image data and outputs audio data through the notebook computer, the user at the display side may experience bad use experience, that is, the external display sees an image frame, but the audio data corresponding to the image frame is transmitted from the remote notebook computer, and the user may not hear the audio data clearly or have no sense of coordination between the audio data and the image data. In this scenario, a user may connect other effective audio devices to the external display device when wanting to adjust the position of the audio output.
Step 104: and if the connection information indicates that the audio equipment is connected, transmitting target information to the electronic equipment, wherein the target information is used for enabling the electronic equipment to be switched from the first audio mode to a second audio mode, and the second audio mode is a mode for transmitting audio data.
Wherein the target information is related to audio configuration information.
If the output device detects that the effective audio device is connected, the electronic device needs to be informed, the effective audio device capable of being used is available on the output device side, so that the electronic device modifies the configuration information of the audio mode, and then the electronic device transmits the audio data to the output device in a new audio mode, and the output device outputs the audio data.
According to the processing method, in the process that the electronic equipment outputs the image data through the output equipment and outputs the audio data through the audio equipment of the electronic equipment, the output equipment can detect whether the output equipment is connected with the effective audio equipment in real time, under the condition that the effective audio equipment exists, the switching of audio output from the electronic equipment side to the output equipment side can be automatically controlled, the whole implementation process does not need user participation, and the processing method is convenient and fast, so that the use experience of a user is improved.
In the above embodiment, the target information may be second attribute information, and before the transmitting the first attribute information to the electronic device, the method may include: physically connecting the electronic device, wherein the absence of the connection enables the electronic device to obtain the attribute information. The physical connection is a physical connection in a power-on state, and the output device can transmit the first attribute information to the electronic device only in the power-on state. The first attribute information may be transmitted to the electronic device by the output device in a process of establishing a connection between the electronic device and the output device on the premise of physical connection.
Based on the above, if the connection information indicates that the audio device is connected, the transmitting the target information to the electronic device may include: and if the connection information indicates that the audio equipment is connected, sending a signal representing disconnection and physical connection again to the electronic equipment under the condition of keeping physical connection with the electronic equipment, so that the electronic equipment obtains the second attribute information after obtaining the signal representing disconnection and physical connection again. The signal representing disconnection and physical connection again can be understood as a hot plug signal, that is, connection of the output device and the electronic device is reestablished on the premise that physical connection of the output device and the electronic device is maintained.
The first attribute information comprises information that the output equipment cannot transmit audio data, and is obtained by the electronic equipment after the electronic equipment is connected with the output equipment for the first time; the second attribute information includes information that the output device is capable of transmitting audio data, which is obtained by the electronic device after it is connected to the output device for the second time. In this embodiment, the second attribute information may also be EDID, but in this implementation, the status parameter of the EDID regarding the audio function may be on, that is, indicate that the output device is capable of outputting audio.
Fig. 2 is a flowchart of another processing method disclosed in the embodiment of the present application, and the method shown in fig. 2 is also applied to an output device. As shown in fig. 2, the processing method may include:
step 201: transmitting first attribute information to an electronic device, wherein the first attribute information comprises display parameter information.
Step 202: first image data sent by the electronic equipment in a first audio mode is obtained and output.
The first image data is determined by the electronic equipment at least according to the display parameter information, and the first audio mode is a mode of not transmitting audio data.
Step 203: in the process of outputting the first image data, connection information of an audio device is detected.
Step 204: and if the connection information indicates that the audio equipment is connected, transmitting target information to the electronic equipment by sending a signal representing disconnection and physical connection again to the electronic equipment.
Wherein the target information is used to cause the electronic device to switch from the first audio mode to a second audio mode, the second audio mode being a mode of transmitting audio data.
Step 205: and outputting and displaying third image data in the process of sending a signal representing disconnection and physical connection again to the electronic equipment until second image data is obtained.
Wherein the third image data is data generated by the output device. The second image data is image data determined by the electronic equipment based on the second attribute information.
Under normal conditions, in the process of realizing hot plug between the output device and the electronic device, the display screen of the output device may have a screen blacking condition for a period of time, but in the scheme disclosed in the embodiment of the present application, if the display screen of the output device is suddenly blacked, a user may not know what condition occurs. Therefore, in order to optimize the user experience, in the embodiment of the application, during the process of implementing hot plug between the output device and the electronic device, the display screen of the output device is controlled to output the third image data so as to prompt the user that the output device is currently performing some work.
The third image data may be an OSD (on-screen display), which may be specifically a customized image generated based on the connection information; for example, the connection information indicates connection information of a headphone, the third image data may be image data including a prompt "headphone is being inserted". Alternatively, the third image data may also be a predefined standard image, i.e. determined to be automatically output when the output device is in a certain scene; for example, when it is determined that the output device is in a hot plug stage, an image including the word "parameter configuration is in progress, please later" is output on the display screen. As shown in fig. 3, an exemplary diagram of the third image data including the wording "insert earphone, please later" is output for the output device.
The third image data is used for prompting the user that the output device is currently working, so that the feeling that the user is boring to wait before the output device restarts outputting the image data sent by the electronic device can be reduced. In some implementations, data relating to the expected wait time may also be included in the third image data to enable a user to determine an approximate wait time. For example, the third image data may further include a word "expected wait time 6 seconds", or a screen for outputting a countdown of the wait time, so as to provide a better use experience for the user. Wherein the expected wait time may be determined based on historical data.
It should be noted that the third image data is data generated by the output device and stored locally in the output device, and when the third image data needs to be displayed, the output device can be directly called from the local memory. And the first image data and the second image data are image data received from the electronic device.
After step 205, step 206 is entered.
Step 205: the second image data is obtained.
And after receiving the second image data, the output device controls the display and output of the second image data according to a normal processing flow.
In this embodiment, in the process of implementing hot plug with the electronic device, the third image data for prompting the user is displayed on the display screen, so that the user is reminded that the output device is performing return work, and the boring waiting feeling of the user is reduced.
In one implementation, before sending the hot plug signal to the electronic device, the method may further include: saving at least part of the first image data; and outputting and displaying at least part of the data in the process of sending the signal representing that the electronic equipment is disconnected and physically connected again to the electronic equipment to obtain the second image data.
In the implementation, at least part of data of the first image data is firstly stored before the output device sends a hot plug signal to the electronic device, and the at least part of data is output in the process of realizing the hot plug of the output device and the electronic device, so that when a user waits for the output device to output the image data sent by the electronic device again, the picture displayed by a display screen of the output device is richer; meanwhile, when the output device restarts to output the image data sent by the electronic device, the user can be associated with the first image data output before more quickly. Thus, the at least part of the data may be a last frame image in the first image data output on the output device.
And in the process of sending a signal representing disconnection and physical connection again to the electronic equipment to obtain the second image data, outputting and displaying at least part of the data, and simultaneously displaying and outputting the third image data to prompt a user to perform relevant work of output equipment.
It should be noted that, in some implementations, the third image data needs to be displayed and output simultaneously with the first image data or the second image data, and the display layer of the third image data is always located on the display layer of the first image data or the second image data, that is, the display output of the first image data or the second image data does not affect the display output of the third image data. As shown in fig. 4, an exemplary diagram of the output of the first image data and the third image data which is displayed on the top layer "inserting a headphone" and forms a partial occlusion for the first image data is displayed simultaneously.
In one implementation, the target information may be used to configure a target application of the electronic device such that the configured target application instructs output of audio data to the output device; the target application is an application corresponding to the audio processor, and the application corresponding to the audio processor may be a sound card driver under the operating system.
Specifically, the target information includes instruction information, and the transmitting the target information to the electronic device may include: and transmitting the target information to a firmware system of the electronic equipment through an interface supporting bidirectional communication, so that after the firmware system analyzes the instruction information, an operating system is triggered to call the target application and realize the configuration of the target application. Wherein the instruction information is used for indicating the configuration information of the target application to be modified.
The firmware system may be motherboard firmware of the electronic device, or may be graphics card firmware of the electronic device. In order to better understand the specific implementation of the embodiment, the following respectively illustrates the processing flows of the corresponding scenes of the motherboard firmware and the graphics card firmware.
For example, in a scenario where the electronic device is a notebook computer, the corresponding processing flow may include: the processing device of the display equipment detects the earphone insertion signal to generate target information, then the target information is transmitted to the power controller on the notebook computer side through the power controller on the display equipment side, the interface control chip on the notebook computer side receives the target information from the power controller on the notebook computer side and then transmits the target information to the mainboard firmware, and the mainboard firmware analyzes instruction information from the target information and then triggers the operating system to call the sound card drive to realize the configuration of target application.
The interface control chip in the above example may be an EC (Embedded Controller), which is a communication bridge between the power Controller and the firmware.
For example, in the context of a conventional desktop, the corresponding process flow may include: the processing device of the display equipment detects the earphone insertion signal, generates target information, then transmits the target information to the power controller of the display card on the desktop side through the power controller on the display equipment side, and after the display card firmware receives the target information from the power controller of the display card, the command information is analyzed from the target information, and then an operating system is directly triggered to call a sound card driver to realize the configuration of target application.
In the above two examples, the Power controller may be a PD controller (Power Delivery controller) which is a standard protocol processor specified by USB Type-C, and both the display device and the electronic device side must be equipped with the PD controller to work properly.
The interface supporting the bidirectional communication can be but is not limited to comprise a USB Type-C interface, a lightning interface and the like, only the interface is required to be ensured to be capable of supporting the bidirectional communication, and only the HDMI interface and the DP interface with the one-way data transmission function are not suitable for the scheme. Thus, in a corresponding implementation, the electronic device may send the first image data or the second image data to the output device via the interface supporting the bidirectional communication, and the output device may also send the instruction information to the electronic device via the interface supporting the bidirectional communication.
The transmission of the instruction information may be implemented based on a dedicated protocol that can be recognized by both the electronic device and the output device, for example, the transmission of the instruction information may be implemented by VDM (Vendor Defined Message) in USB Type-C protocol.
The firmware system can be firmware of a display card and can be positioned on the integrated display card, so that after the integrated display card receives the target information, the target information is directly decoded through the firmware of the integrated display card to obtain instruction information, then the instruction information is sent to the operating system, the operating system calls target applications related to audio, and configuration of related audio content in the target applications is controlled to be completed.
In one specific implementation, a user inserts an earphone into an external display, the external display sends a message of inserting the earphone to a firmware system of the electronic device through the VDM, the firmware system sends the message to a sound card driver application, and a speaker target is selected as the external display, that is, the external display outputs audio data. Correspondingly, after the user pulls the earphone from the external display, the external display sends the earphone pulling message to a firmware system of the electronic device through the VDM, the firmware system sends the message to the sound card driver application, and the speaker target is selected as the electronic device, namely, the electronic device performs audio output.
It should be noted that, in the implementation of the processing method described in this embodiment, a display screen of the output device is always in an on state during the implementation process, and the output device can normally output the first image data before the audio mode is changed, and directly output the second image data and the audio data after the audio mode is changed. Therefore, from the perspective of the user, the situation of "interruption" of the output image data does not occur, and only the difference between the output of the audio data from the electronic device and the output of the audio data from the output device (earphone) is provided, so that compared with the aforementioned scheme of implementing audio mode switching by transmitting the EDID, the scheme has a good user experience.
