Description of the embodiments
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a flowchart of a processing method according to an embodiment of the present application, where the processing method shown in fig. 1 is applicable to an output device, and the output device can output image data and output audio data by connecting an active audio device. Referring to fig. 1, the processing method may include the steps of:
step 101: and transmitting first attribute information to the electronic equipment, 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 establish a connection, and is used to characterize a relevant output configuration of the output device. In the embodiment of the present application, the first attribute information may, but is not limited to, include display parameter information, for example, the first attribute information may also include related configuration information of 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 transmitted by the electronic device in a first audio mode is obtained and output. The first image data is determined by the electronic device at least according to the display parameter information, and the first audio mode is a mode in which audio data is not transmitted.
After receiving the first attribute information, the electronic device processes the first image data for display output at the output device based on the display parameter information. The first attribute information also enables the electronic device to process audio data to be output based on the first audio mode. In the case where the first attribute information is EDID, the status parameter regarding the audio function in EDID may be off, i.e., 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 at the electronic device side.
In the mode of not transmitting audio data, the electronic device cannot transmit the audio data to the output device, and the output device cannot transmit the audio data acquired by the electronic device to the electronic device. For example. The output device does not transmit sound data collected by the microphone to the electronic device for output even when the microphone is connected.
Step 103: in 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 electronic device in real time, and the audio device can be, for example, an earphone device, an external loudspeaker device and the like.
It can be understood that when a user outputs image data using a display externally connected to a notebook computer and outputs audio data through the notebook computer, a bad use experience may be caused to the user on the display side, that is, the user sees the image picture from the external display, but sound data corresponding to the image picture is transmitted from a remote notebook computer, and the user may not hear clearly or have a sense of harmony of the audio data and the image data. In this scenario, when the user wants to adjust the position of the audio output, other effective audio devices are connected to the external display.
Step 104: and if the connection information indicates that the audio device is connected, transmitting target information to the electronic device, wherein the target information is used for enabling the electronic device to switch 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 valid audio device is connected, the output device needs to "inform" the electronic device, and the output device side has the valid audio device capable of being used, so that the electronic device modifies the configuration information of the audio mode, and then in a new audio mode, the electronic device transmits audio data to the output device, and the output device outputs the audio data.
According to the processing method, in the process that the electronic device outputs image data through the output device and outputs audio data through the audio device of the electronic device, the output device can detect whether the electronic device is connected with the effective audio device or not in real time, and under the condition that the effective audio device exists, the switching of audio output from the electronic device side to the output device side can be automatically controlled, the whole implementation process does not need user participation, and the processing method is convenient and rapid, so that the use experience of a user is improved.
In the foregoing embodiment, the target information may be second attribute information, and before the first attribute information is transmitted to the electronic device, the method may include: and physically connecting the electronic device, wherein the electronic device can obtain the attribute information from the absence of a connection to the physical connection. The physical connection is 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 foregoing, if the connection information indicates that an audio device is connected, transmitting 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 that the physical connection with the electronic equipment is kept, 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, i.e. a connection re-establishment between the output device and the electronic device is realized on the premise of maintaining the physical connection between the output device and the electronic device.
The first attribute information comprises information that the output device cannot transmit audio data, and the information is obtained by the electronic device after the electronic device is connected with the output device 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 a second time. In this embodiment, the second attribute information may be EDID, but in this implementation, the status parameter related to the audio function in EDID may be on, that is, indicating that the output device is capable of audio output.
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 equally applied to an output device. As shown in connection with fig. 2, the processing method may include:
step 201: and transmitting first attribute information to the electronic equipment, wherein the first attribute information comprises display parameter information.
Step 202: first image data transmitted by the electronic device in a first audio mode is obtained and output.
The first image data is determined by the electronic device at least according to the display parameter information, and the first audio mode is a mode in which audio data is not transmitted.
Step 203: in 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 in which audio data is transmitted.
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 to obtain the second image data.
Wherein the third image data is data generated by the output device. The second image data is image data determined by the electronic device based on the second attribute information.
Under normal conditions, in the process of hot plug between the output device and the electronic device, a black screen condition occurs on the display screen of the output device for a period of time, but in the scheme disclosed by the embodiment of the application, if the display screen of the output device is suddenly black screen, a user may not know what condition occurs. Therefore, in order to optimize user experience, in the embodiment of the application, in 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 doing some work.
The third image data may be 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 the earphone, and the third image data may be image data including a prompt "earphone is being inserted". Alternatively, the third image data may also be a predefined standard image, i.e. it is determined that the predefined standard image is automatically output when the output device is in a certain scene; for example, when it is determined that the output device is in the hot plug phase, an image including the word "ongoing parameter configuration, please be later" is output on the display screen. As shown in fig. 3, an exemplary diagram of the output device outputting the third image data includes the word "insert earphone, please be later".
The third image data is used for prompting the user to output the current work of the device, so that the feeling of boring waiting of the user before the output device restarts to output the image data sent by the electronic device can be reduced. In some implementations, related data of the expected wait time may also be included in the third image data to enable the user to determine the approximate wait time. For example, the third image data may further include a word of "predicted wait time 6 seconds" or a screen of output wait time countdown 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 that is generated by the output device and stored locally to the output device, and when the third image data needs to be displayed, the output device may 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 206: and obtaining the second image data.
And after receiving the second image data, the output device controls the display output of the second image data according to the normal processing flow.
In this embodiment, in the process of implementing hot plug between the output device and the electronic device, third image data for prompting the user is displayed on the display screen, so that on one hand, the user is reminded that the output device is doing work backwards, and on the other hand, the boring waiting feel of the user is reduced.
In one implementation, before the 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 a signal representing disconnection and physical connection 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 the hot plug signal to the electronic device, and the at least part of data is output in the process that the output device and the electronic device realize hot plug, so that when waiting for the output device to output the image data sent by the electronic device again, a user can display a richer picture on a display screen of the output device; and meanwhile, when the output device restarts to output the image data sent by the electronic device, the user can be more quickly associated with the first image data output before. Thus, the at least part of the data may be the last frame of 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 acquire the second image data, outputting and displaying at least part of the data, and simultaneously displaying and outputting the third image data, wherein the prompt of the related work of the output equipment is performed for the user.
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 may be always located above the display layer of the first image data or the second image data, that is, the display and output of the first image data or the second image data may not affect the display and output of the third image data. As shown in fig. 4, an exemplary diagram of the simultaneous display output of the first image data and the third image data, in which the third image data "in-ear headphones" are displayed on the top layer and partially occlude the first image data.
In one implementation, the target information may be used to configure a target application of the electronic device such that the configured target application indicates to output audio data to the output device; the target application is an application corresponding to an audio processor, and the application corresponding to the audio processor can be a sound card driver under an 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 two-way communication, so that the firmware system triggers an operating system to call the target application and realize configuration of the target application after analyzing the instruction information. The instruction information is used for indicating to modify the configuration information of the target application.
The firmware system may be a motherboard firmware of the electronic device, or a graphics card firmware of the electronic device. In order to better understand the specific implementation of the embodiment, the following illustrates the processing flow of the corresponding scenario of the motherboard firmware and the graphics card firmware.
For example, in a scenario where the electronic device is a notebook computer, the corresponding process flow may include: the processing device of the display device detects the earphone insertion signal to generate target information, then the target information is transmitted to the power supply controller of the notebook computer side through the power supply controller of the display device side, after receiving the target information from the power supply controller of the notebook computer side, the interface control chip of the notebook computer side transmits the target information to the main board firmware, and after the main board firmware analyzes instruction information from the target information, the main board firmware triggers the operating system to call the sound card to drive so as to realize the configuration of the target application.
The interface control chip in the above example may be EC (Embedded Controller, embedded processor), which is a communication bridge between the power supply 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 device detects the earphone insertion signal to generate target information, then the target information is transmitted to the power supply controller of the desktop side display card through the power supply controller of the display device side, after the display card firmware receives the target information from the power supply controller of the display card, instruction information is analyzed from the target information, and then an operating system is directly triggered to call the sound card to drive so as to realize the configuration of target application.
In the above two examples, the power supply 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 operate normally.
The interface supporting bidirectional communication can include, but is not limited to, an USB Type-C interface, a lightning interface, etc., only the interface needs to be guaranteed to support bidirectional communication, but only the HDMI interface and the DP interface having unidirectional data transmission function are not suitable for the present scheme. In this way, in a corresponding implementation, the electronic device may send the first image data or the second image data to the output device through the interface supporting two-way communication, and the output device may also send the instruction information to the electronic device through the interface supporting two-way 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, by VDM (Vendor Defined Message ) in the 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 firmware directly decodes the target information to obtain instruction information, then the instruction information is sent to an operating system, the operating system calls a target application related to audio, and the configuration of related audio content in the target application is controlled to be completed.
In one specific implementation, a user inserts an earphone on an external display, the external display sends a message of inserting the earphone to a firmware system of the electronic device through a VDM, the firmware system sends the message to a sound card driving application, and a speaker target is selected as the external display, namely, the external display outputs audio data. Correspondingly, after the user pulls out the earphone from the external display, the external display sends a message of pulling out the earphone to a firmware system of the electronic device through the VDM, the firmware system sends the message to a sound card driving application, and a loudspeaker target is selected as the electronic device, namely, the electronic device carries out audio output.
It should be noted that, in the implementation of the processing method described in this embodiment, the display screen of the output device is always in an on state in the implementation process, and the first image data can be normally output before the audio mode is changed, and the second image data and the audio data are directly output by the output device after the audio mode is changed. Therefore, from the perspective of a user, the situation of 'interrupt' of output image data is avoided, and only the difference from the output of audio data from the electronic equipment to the output of audio data from the output equipment (earphone) is avoided, so that compared with the scheme of realizing audio mode switching through transmission EDID, the method has good user experience.
For the foregoing method embodiments, for simplicity of explanation, the methodologies are shown as a series of acts, but one of ordinary skill in the art will appreciate that the present application is not limited by the order of acts, as some steps may, in accordance with the present application, occur in other orders or concurrently.
