Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Referring to fig. 1, fig. 1 is an architecture diagram illustrating an image transmission according to an exemplary embodiment.
As shown in fig. 1, the architecture diagram may include a first electronic device 10, a cloud server 11, and a second electronic device 12. In the case that the screen of the first electronic device 10 displays an image (such as playing a video, etc.), the first electronic device 10 may transmit the image displayed by the first electronic device to the cloud server 11, and transmit the image to the second electronic device 12 by the cloud server 11, so that the screen of the second electronic device 12 displays the image displayed by the first electronic device 10; in addition, in the process of displaying an image by the second electronic device 12, the second electronic device 12 may also receive an operation input by a user for the display interface, the second electronic device 12 transmits operation information of the received operation to the first electronic device 10 through the cloud-real-machine server 11, and the first electronic device 10 may perform a corresponding operation (such as pausing video playback) on the displayed image when receiving the operation information, so that the second electronic device 12 may experience the configuration of the first electronic device 11 without the configuration of hardware, systems, and the like of the first electronic device 11.
The first electronic device 10 and the second electronic device 12 may be devices with communication functions, such as a mobile phone, a tablet computer, and an all-in-one machine, and may also be devices simulated by a virtual machine or a simulator. The cloud server 11 may be a device having storage and computing functions, such as a cloud server or a server cluster.
Referring to fig. 2, a flowchart of an image transmission method according to an exemplary embodiment is shown, the image transmission method is applied to the above-mentioned architecture, and the image transmission method can be executed by the first electronic device 10 shown in fig. 1. As shown in fig. 2, the image transmission method may specifically include the following steps:
step 201, detecting equipment operation parameters of first electronic equipment under the condition that an image is displayed on a display interface of the first electronic equipment;
step 202, determining transmission associated information of the first electronic equipment based on the equipment operation parameters;
step 203, transmitting the image to a cloud real machine server according to the transmission associated information, so that the cloud real machine server transmits the image to a second electronic device.
Therefore, in the process of displaying an image on the display interface of the first electronic device 10, the transmission related information corresponding to the device operation parameter can be determined according to the device operation parameter, and the displayed image is transmitted to the cloud terminal server 11 according to the determined transmission related information, so that in the process of transmitting an image to the second electronic device 12 by the first electronic device 10 through the cloud terminal server 11, the transmission related information of the first electronic device 10 can be dynamically adjusted based on the device operation parameter of the first electronic device 10, and the flexibility of image transmission of the first electronic device 10 is improved.
The above steps are described in detail below, specifically as follows:
in step 101, the image displayed by the first electronic device 10 may be any image displayed in the display interface thereof, for example, the image frame of the first electronic device 10 during video playing, a photo displayed during photo album browsing, or a display page of an application program, such as a payment page, a web page, or an instant chat page, etc.
In the embodiment of the present disclosure, the first electronic device 10 detects the device operation parameter thereof, which may be automatically triggered by the first electronic device 10, for example, the first electronic device 10 detects the device operation parameter according to the environment where the first electronic device is located, such as detecting when the first electronic device is located in a preset environment; or, during the process of transmitting the image from the first electronic device 10 to the second electronic device 11 through the cloud-real machine platform 11, detecting the device operating parameters at preset time intervals, and the like.
Of course, the above-mentioned first electronic device 10 may detect the device operating parameter thereof, or the first electronic device 10 may detect the device operating parameter thereof according to a request initiated by the second electronic device 12, specifically, the method may include: under the condition that the second electronic device 12 receives the first operation, generating a preset request according to the first operation, and sending the preset request to the cloud real machine server 11; the cloud real machine server 11 sends the received preset request to the first electronic device 10, and the first electronic device 10 detects the device operation parameters thereof in response to the preset request.
Here, the first operation may be any operation that the second electronic device 12 receives the user input thereof and is used for instructing to generate the preset request, and may be at least one of a voice operation, a gesture operation, a touch operation, or the like, which is not limited herein.
In addition, the device operation parameter may be any parameter that has an influence on the operation of the electronic device, and specifically, the device operation parameter may include at least one of a hardware parameter, a system version, and a network speed of the first electronic device 10, so that the manner in which the first electronic device dynamically adjusts and transmits the associated information based on the device operation parameter of the first electronic device is more flexible, and the flexibility in which the first electronic device transmits the image is further improved.
The hardware parameter may be a parameter of at least one of hardware such as a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), and a memory; the system version may be a version number of an operating system of the first electronic device 10, for example, the system version is Android (Android)6.0 or Android 10.0, and the like; the network speed may be a bandwidth of the first electronic device 10 currently connected to the network, and the network speed may be obtained through a traffic statistic module (e.g., TrafficStats class, etc.).
In step 202 above, after the first electronic device 10 detects its device operating parameters, transmission associated information with the first electronic device 10 may be determined based on the detected device operating parameters.
In the embodiment of the present disclosure, the determining of the transmission related information of the first electronic device 10 based on the device operating parameter may be determining the transmission related information corresponding to the device operating parameter according to a preset rule. Specifically, the first electronic device 10 may preset a corresponding relationship between information of the first electronic device 10 and the associated information, and the first electronic device 10 may determine the associated information having a corresponding relationship with the device operating parameter thereof as the transmission associated information of the first electronic device 10.
For example, assuming that the device operation parameter includes the network speed, a corresponding relationship between a speed range 1 and associated information 1 and a corresponding relationship between a speed range 2 and associated information 2 are preset in the first electronic device 10, and if the network speed detected by the first electronic device 10 is in the speed range 1, the associated information 1 is determined as the transmission associated information; similarly, if the network speed detected by the first electronic device 10 is in the speed range 2, the association information 21 is determined as the transmission association information.
In addition, the transmission related information may be any information that can affect the process of the first electronic device 10 transmitting the image to the second electronic device 12 through the cloud server 11.
In this embodiment of the disclosure, because different image transmission manners may have different influences on the image transmission process, and there are multiple image transmission manners that can be used for transmitting images, in order to implement that the image transmission manner of the first electronic device 10 in the image transmission process is adjustable, the transmission related information may include the image transmission manner, that is, the step 202 may include: determining an image transmission mode of the first electronic device 10 based on the device operation parameters; accordingly, the step 203 may include: and transmitting the image to the cloud real machine server 11 according to the image transmission mode.
Here, the first electronic device 10 may determine an image transmission mode corresponding to the device operating parameter, and transmit the image to the cloud server 11 according to the determined image transmission mode, so that in a process that the first electronic device 10 transmits the image to the second electronic device 12 through the cloud server 11, the first electronic device 10 may dynamically adjust the image transmission mode in time, so that the image transmission mode adopted by the first electronic device 10 is more appropriate, and not only may the flexibility of image transmission be improved, but also the image transmission quality may be improved.
For example, when the operating system version of the first electronic device 10 is Android 5.0, the first electronic device 10 transmits the displayed image to the cloud-real machine server 11 through the image transmission method 1, and when the operating system of the first electronic device 10 is upgraded from the Android 5.0 to the Android 10.0, the first electronic device 10 may determine the image transmission method 2 corresponding to the Android 10.0 according to a corresponding relationship between a preset version number and the image transmission method, and then the first electronic device 10 may update the image transmission method used in the image transmission process from the image transmission method 1 to the image transmission method 2 in time.
The image transmission method may be any method that can be used for the first electronic device 10 to transmit an image, and specifically, the image transmission method may include a picture stream method or a video stream method.
The picture streaming manner is that, in the process of transmitting a picture by the first electronic device 10, the first electronic device 10 may capture an image displayed by the first electronic device 10, compress the captured image in a preset image format, and transmit the compressed image to the second electronic device 12 through the cloud server 11, and the second electronic device 12 may decompress the compressed image and display the compressed image according to the preset image format. For example, the above-described picture stream scheme may be a scheme for transmitting an image based on a screen copy tool minicap or the like.
In addition, the video streaming method is that, in the process of transmitting an image by the first electronic device 10, the first electronic device 10 directly acquires original data of the image displayed by the first electronic device 10, encodes the acquired original data, and transmits the encoded original data to the second electronic device 12 through the cloud terminal server 11, and the second electronic device may decode the encoded original data and display an image generated by decoding, and a format of the displayed image may be set in the decoding process. For example, the video streaming mode may be a mode of transmitting an image based on a wireless screen projection tool scrcpy, and in the process of transmitting an image by using scrcpy, the original data may be h.264 encoded.
In the above-mentioned picture stream mode, the image intercepted and transmitted by the first electronic device 10 is a partial image frame in an image frame (such as a playing video, or a display picture, etc.) displayed on a display interface of the first electronic device, for example, the first electronic device 10 may perform a screenshot operation at intervals of a preset image frame; in the video streaming mode, the first electronic device 10 may transmit raw data of each image frame, that is, the image is all image frames in the image frames displayed on the display interface of the first electronic device 10.
In this embodiment of the disclosure, since different parameters of the image transmission index associated with the image transmission mode of the first electronic device 10 may also have different effects on image transmission when the first electronic device 10 transmits the image according to the image transmission mode thereof, in order to realize that the transmission index parameter of the first electronic device 10 (i.e. the parameter of the image transmission index associated with the image transmission mode of the first electronic device 10) during the image transmission is adjustable, step 202 may include: determining a transmission index parameter of the first electronic device based on the device operating parameter, wherein the transmission index parameter is a parameter value of an image transmission index associated with an image transmission mode of the first electronic device; accordingly, the step 203 may include: and transmitting the image to a cloud real machine server according to the transmission index parameter in the image transmission mode.
Here, in the process of transmitting an image to the second electronic device 12 through the cloud-real-machine server 11, the first electronic device 10 may determine a transmission index parameter corresponding to the device operation parameter, and perform image transmission according to the determined transmission index parameter, so that in the process of transmitting an image by the first electronic device 10 in the image transmission mode, the parameter of the image transmission index associated with the image transmission mode may be adjusted in time, so that the transmission index parameter adopted by the first electronic device 10 is more appropriate, which not only improves the flexibility of image transmission, but also improves the image transmission quality.
The image transmission method of the first electronic device 10 may be an image transmission method fixedly set in the first electronic device 10; alternatively, the image transmission method determined by the device operation parameter, that is, before determining the transmission index parameter of the first electronic device 10 based on the device operation parameter, may further include: based on the device operating parameters, the image transmission mode of the first electronic device is determined, so that in the process of transmitting the image by the first electronic device 10, the image transmission mode and the parameter value of the image transmission index associated with the image transmission mode can be adjusted simultaneously through the device operating parameters, and the flexibility and quality of image transmission are further improved.
As can be seen from the above, the image transmission method may be the above-mentioned picture stream method, that is, the transmitting the image to the cloud-real-machine server according to the transmission index parameter in the image transmission method may include:
intercepting the image according to the transmission index parameter, and transmitting the intercepted image to a cloud real machine server, wherein the intercepted image is as follows: the display interface of the first electronic device displays a part of the image frames.
Here, in the case that the first electronic device 10 transmits an image in the picture stream mode, it is possible to adjust the parameter of the image transmission index associated with the picture stream mode in time.
It should be noted that the transmission index parameter associated with the picture stream mode may be any parameter of an image transmission index associated with the picture stream mode, and in the process of transmitting an image in the picture stream mode, because the first electronic device 10 intercepts and compresses the image displayed by the first electronic device, in order to adjust the parameter of the relevant index in the image intercepting and compressing process, specifically, the transmission index parameter may include at least one of an image resolution and an image compression quality, so that at least one of the parameters of the image resolution, the image compression quality, and the like in the process of transmitting an image in the picture stream mode may be adjusted in time, and the transmission index parameter is appropriate, thereby improving the transmission rate of the picture stream and the refresh rate of the image displayed by the receiving end.
For example, after the image is cut, the first electronic device compresses the cut image in a JPEG format, selects different compression quality parameters among the quality parameters of the high, medium, and low levels, and compresses the cut image according to the selected compression quality parameters.
Of course, the image transmission method may be the video streaming method, that is, the transmitting the image to the cloud server according to the transmission index parameter in the image transmission method may include:
acquiring original data of the image, encoding the original data according to the transmission index parameter, and transmitting the encoded original data to a cloud real machine server, wherein the image is as follows: all the image frames displayed on the display interface of the first electronic equipment.
Here, in the case that the first electronic device 10 transmits images in the video streaming manner, it is possible to realize timely adjustment of parameters of image transmission indexes associated with the video streaming manner.
In the process of transmitting images in the video streaming manner, because the first electronic device 10 encodes the original data, in order to adjust the parameters of the relevant indexes in the encoding process, specifically, the transmission index parameter may include at least one of a video resolution, a frame rate, and a code stream, so that the parameter of at least one of a video resolution, a frame rate, and a code stream in the process of transmitting images in the video streaming manner can be adjusted in time.
For example, the first electronic device 10 may obtain raw data of a display image thereof through a raw data tool (e.g., surface control), and encode the obtained raw data using a multimedia coding tool (e.g., MediaCodec), and during the encoding process, the first electronic device 10 may select relevant parameters during encoding, such as at least one of video resolution, frame rate, and code stream, according to at least one of a hardware parameter, a system version, and a network speed of the first electronic device.
In step 203, after the first electronic device 10 determines the transmission related information thereof, the first electronic device 10 may transmit the image displayed by the first electronic device 10 to the cloud-to-live server 11 according to the determined transmission related information, so as to transmit the image to the second electronic device 12 through the cloud-to-live server 11 for display.
For example, when the transmission related information is in a picture stream mode, the first electronic device 10 may transmit the compressed screenshot to the cloud server 11; when the transmission-related information is in a video streaming mode, the first electronic device 10 may transmit the encoded original data (e.g., Network Abstraction Layer Unit (NALU) of the h.264-encoded Network) to the cloud server 11.
In the embodiment of the present disclosure, when the transmission-related information is an image transmission method, the first electronic device 10 transmits the image displayed on the display device to the cloud-reality server 11 according to the transmission-related information, and performs image transmission on an image transmission mapping link related to the image transmission method of the first electronic device 10.
The image transmission mapping link associated with the image transmission mode of the first electronic device 10 may be an image transmission mapping link established after the first electronic device 10 determines the image transmission mode thereof.
