Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0063] The present application provides a method, device, electronic device, and storage medium for converting DP signals, which are described in detail below.

[0064] See also Figure 1 , Figure 1 This is a schematic diagram of a scenario of a system for converting DP signals provided in an embodiment of the present application.

[0066] In the embodiment of the present application, the electronic device 100 and other devices can transmit video data via the User Datagram Protocol (UDP), such as the DP signal transmission protocol. Of course, other types of transmission methods can also be used, including solutions that can transmit DP data wirelessly, and the specific embodiments of the present application are not limited thereto.

[0067] It should be noted that Figure 1 The scenario diagram of the system for converting DP signals shown is merely an example. The system and scenario for converting DP signals described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person skilled in the art will appreciate that, with the evolution of the system for converting DP signals and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is equally applicable to similar technical problems.

[0068] like Figure 2 As shown, Figure 2 This is a flow chart of an embodiment of a method for converting a DP signal in an embodiment of the present application. The method is applied to a target device, and the target device includes a signal converter. The method for converting a DP signal may include the following steps 201 to 203:

[0069] 201. Obtain an input target DP signal.

[0070] In the embodiments of the present application, the DP signal refers to the DisplayPort (DP) signal, which is a digital video interface standard developed by VESA (Video Electronics Standards Association) for connecting a computer to a monitor or other display device. For example, a target DP signal transmitted by another device via a data line can be obtained through any data interface on the target device.

[0071] 202. Input the target DP signal to the signal converter and convert it into a target type of video signal.

[0072] Under normal circumstances, devices such as mobile phones and tablets do not have data protocols related to DP signals. Therefore, these devices cannot play videos corresponding to DP signals. Based on this, a device that can convert DP signals into target type video signals can be installed in the target device. For example, a DP2MIPI chip can be installed, and the DP2MIPI chip can be integrated into the device. After the target device obtains the DP signal, the DP2MIPI chip can convert the DP signal into a video format supported by the target device, such as MP4, AVI, HDMI, etc. After that, the device can play normally. Which format to choose specifically depends on the video format actually supported by the target device, and the embodiments of the present application do not limit it.

[0073] 203. Output a video signal of the target type.

[0074] According to the above steps, the DP2MIPI chip can convert the DP signal into a video format supported by the target device. At this time, after the video format conversion is completed, the target device can output the converted video signal, for example, to the display device of the target device for output, or to other display devices that are connected to the target device for data such as screen projection or network connection, etc., which is not limited in the embodiments of this application.

[0075] The method for converting DP signals provided in this application can install an additional signal converter for converting DP signals in a target device that does not support DP signals. After obtaining the DP signal, the DP signal converter can convert the DP signal into a video signal supported by the target device, allowing the target device to play videos that were originally not playable.

[0076] To better implement the embodiments of the present application, in one embodiment of the present application, the target device further includes a DP signal identifier; before obtaining the input target DP signal, the method further includes:

[0077] The input initial audio and video signal is obtained; if the DP signal identifier confirms that the initial audio and video signal is a DP signal, it is confirmed that the target DP signal is obtained.

[0078] In actual situations, other electronic devices may include DP signals when transmitting video data to the target device, and of course, may also include video formats supported by the target device itself. Therefore, not all input audio and video signals require format conversion. Therefore, the embodiment of the present application also adds a DP signal identifier to identify whether the input video signal is a DP signal. If it is a DP signal, conversion is performed. Otherwise, the target device can directly output the video.

[0079] Specifically, the DP signal identifier can be a PD3.0 controller. After receiving the initial audio and video input signal, the DP signal identifier can identify it. If it is a DP signal, it can then control the DP2 MIPI chip to operate. Otherwise, the target device can directly output the video based on the initial audio and video input signal.

[0080] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target device further includes a signal repeater; inputting the target DP signal to the signal converter includes:

[0081] According to the target DP signal, the signal repeater and the signal converter are controlled to be turned on; the target DP signal is input into the signal repeater to obtain the target enhanced DP signal; and the target enhanced DP signal is input into the signal converter to obtain the target type of video signal.

[0082] The above embodiment provides a solution for converting the DP signal into a video format supported by the target device. In order to avoid signal loss during the signal conversion process, the embodiment of the present application also provides a solution for enhancing the signal.

[0083] Specifically, an additional signal repeater Redriver can be installed for the target device to enhance the input target DP signal. After that, the enhanced target enhanced DP signal can be converted.

[0084] To better implement the embodiments of the present application, in one embodiment of the present application, the target device further includes an audio signal converter; the target DP signal further includes an initial audio signal; and the method further includes:

[0085] The initial audio signal is input into the signal converter to obtain a first audio signal; the first audio signal is input into the audio signal converter to obtain a second audio signal; and the second audio signal is output.

[0086] The above embodiment provides a solution for converting the DP signal into a video format supported by the target device. However, only completing the conversion of the video image without matching the audio will result in missing video content. Therefore, in order to prevent missing video content, the embodiment of the present application also provides a solution for converting the audio at the same time.

[0087] Specifically, since the input target DP signal includes not only a video signal but also an audio signal. Therefore, while the video signal in the DP signal is converted by the signal converter, the audio signal in the target DP signal is also converted into an audio format supported by the target device, such as MP3. For example: the initial audio signal is transmitted to the signal converter DP2MIPI and converted into an I2S signal, that is, the first audio signal; then, the audio signal converter Audio DAC converts the I2S digital signal into an analog signal, that is, the second audio signal. Finally, the second audio signal is transmitted to the speaker to output the audio. In this way, by converting the audio at the same time through the signal converter, the simultaneous conversion of the target DP signal, video and audio can be completed, so that the target device can play the complete audio and video.

[0088] In order to better implement the method for converting DP signals in the embodiment of the present application, in addition to the method for converting DP signals, an apparatus for converting DP signals is also provided in the embodiment of the present application, which includes: a processor 301, a signal converter 302 and a display 303; the signal converter 302 is electrically connected to the interface for receiving the input signal and the processor 301 respectively; the processor 301 is electrically connected to the display 303; the signal converter 302 is used to convert the DP signal into a target signal; the processor 301 is used to control the display 303 to output a video according to the target signal; the display 303 is used to play the video screen corresponding to the target signal, specifically as shown in FIG. Figure 3 shown.

[0089] In order to better implement the embodiment of the present application, in one embodiment of the present application, the target device further includes: a first switch 304 and an image sensor 305; the image sensor 305 is electrically connected to the first switch 304; the signal converter 302 is electrically connected to the interface for receiving the input signal and the first switch 304 respectively; the first switch 304 is electrically connected to the processor 301; the image sensor 305 is used to obtain the captured image information; the first switch 304 is used to control the conduction between the signal converter 302 and the processor 301; or the first switch 304 is used to control the conduction between the image sensor 305 and the processor 301, specifically as follows Figure 4 shown.

[0090] It should be noted that in some cases, devices such as mobile phones or tablets also have an image sensor 305, including a camera. The camera is also an input device for video signals. In order to save the internal integrated circuits of the device, the first switch 304 can be added, such as Figure 4As shown, the switching direction of the first switch 304 can connect the signal converter 302 and the processor 301. In this case, the path between the image sensor 305 and the processor 301 needs to be disconnected. In this way, the video signal converted by the signal converter 302 will not be affected by the video signal of the image sensor 305. Similarly, if the path between the image sensor 305 and the processor 301 is connected, it will not be affected by the video signal converted by the signal converter 302. This can preserve the original application of the camera in the mobile phone or tablet.

[0091] In order to better implement the embodiment of the present application, in one embodiment of the present application, the target device further includes: a DP signal identifier 306 and a signal repeater 307; the DP signal identifier 306 is electrically connected to the interface for receiving the input signal and the processor 301 respectively; the signal repeater 307 is electrically connected to the processor 301 and the signal converter 302 respectively; the DP signal identifier 306 is used to detect whether the input signal is a DP signal; the signal repeater 307 is used to enhance the input DP signal; the processor 301 is also used to control the opening or closing of the signal converter 302 and the signal repeater 307, as shown in FIG. Figure 5 shown.

[0092] After confirming that the input video signal is the target DP signal, the DP signal identifier 306 sends a DP signal confirmation signal to the processor 301. At this point, the processor 301 controls the signal repeater 307 and the signal converter 302 to turn on. The DP signal identifier 306 then inputs the target DP signal to the signal repeater 307 for signal amplification. The amplified signal is then fed through the signal repeater 307 to the signal converter 302. The signal converter 302 then returns the converted video format input to the processor 301, which then outputs it to the display 303 for video output.

[0093] In order to better implement the embodiments of the present application, in one embodiment of the present application, the target device further includes: a second switch 308, an audio signal converter 309, a third switch 310 and a speaker 311; the second switch 308 is electrically connected to the interface for receiving the input signal and the signal converter 302 respectively; the signal converter 302 is also electrically connected to the audio signal converter 309; the third switch 310 is electrically connected to the processor 301, the audio signal converter 309 and the speaker 311 respectively; the third switch 310 is used to control the conduction between the audio signal converter 309 and the processor 301 and the speaker 311; the speaker 311 is used to output the audio signal; the second switch 308 is used to control the conduction between the interface for receiving the input signal and the signal converter 302; the audio signal converter 309 is used to convert the audio signal in the DP signal into the target audio signal, specifically as Figure 6 shown.

[0094] In order to better implement the embodiment of the present application, in one embodiment of the present application, a structural diagram of an overall target device is also provided, and the target device includes: a processor 301, a signal converter 302 and a display 303; the signal converter 302 is electrically connected to the interface for receiving the input signal and the processor 301 respectively; the processor 301 is electrically connected to the display 303; the signal converter 302 is used to convert the DP signal into a target signal; the processor 301 is used to control the display 303 to output the video according to the target signal; the display 303 is used to play the video image corresponding to the target signal; the first switch 304 and image sensor 305; the image sensor 305 is electrically connected to the first switch 304; the signal converter 302 is electrically connected to the interface for receiving input signals and the first switch 304 respectively; the first switch 304 is electrically connected to the processor 301; the image sensor 305 is used to obtain the captured image information; the first switch 304 is used to control the conduction between the signal converter 302 and the processor 301; or the first switch 304 is used to control the conduction between the image sensor 305 and the processor 301; the DP signal identifier 306 and the signal repeater 307; the DP signal identifier 30 6 are electrically connected to the interface for receiving input signals and the processor 301 respectively; the signal repeater 307 is electrically connected to the processor 301 and the signal converter 302 respectively; the DP signal identifier 306 is used to detect whether the input signal is a DP signal; the signal repeater 307 is used to enhance the input DP signal; the processor 301 is also used to control the opening or closing of the signal converter 302 and the signal repeater 307; the second switch 308, the audio signal converter 309, the third switch 310 and the speaker 311; the second switch 308 is electrically connected to the interface for receiving input signals and the signal converter 301 respectively; 2 is electrically connected; the signal converter 302 is also electrically connected to the audio signal converter 309; the third switch 310 is electrically connected to the processor 301, the audio signal converter 309 and the speaker 311 respectively; the third switch 310 is used to control the conduction between the audio signal converter 309 and the processor 301 and the speaker 311; the speaker 311 is used to output the audio signal; the second switch 308 is used to control the conduction between the interface for receiving the input signal and the signal converter 302; the audio signal converter 309 is used to convert the audio signal in the DP signal into a target audio signal, which can be specifically as follows Figure 7 shown.

[0095] The overall process includes: when the DP signal is connected to the target device, the PD3.0 controller recognizes the DP signal. In terms of display, it sends a signal to the CPU through I2C. The CPU controls the Redriver and DP2MIPI through I2C to open.
