Background
With the development of communication technology, electronic devices have increasingly powerful functions, for example, a user can synchronously display a picture of a small-screen device on a screen of a large-screen device through a wireless screen projection technology.
In the process of wireless screen projection, the resolution and the frame rate of output screen pictures at the source end of a small-screen device are set to be lower maximum values, for example, the frame rate is 30fps at most and the resolution is 1080p at most.
However, in the case that the frame rate of the video source is higher than 30fps or the resolution is higher than 1080p, and the large-screen device supports higher resolution or frame rate, the small-screen device can only project the screen at the frame rate of 30fps and the resolution of 1080p, which limits the display capability of the large-screen device, and thus the display effect of the video resource projected during the screen projection process is not good.

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.

The data processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flowchart of a data processing method according to an embodiment of the present application. As shown in fig. 1, the method includes the following S101 and S102:
s101, the sending end equipment adjusts data parameters of data to be transmitted according to at least one of a network transmission state and playing parameters of the receiving end equipment.
It should be noted that, in the embodiment of the present application, the data to be transmitted may be text data, image data, or audio data, and this is not specifically limited in the embodiment of the present application.
For convenience of explanation, the following description takes the example of the sending-end device projecting a screen to the receiving-end device.
For example, in the embodiment of the present application, the sending end device may be an electronic device with a smaller screen size, such as a mobile phone, a tablet computer, a notebook computer, and the like; the receiving end device may be an electronic device with a larger screen size, such as a tablet computer, a television, a projector, and the like.
In this embodiment, the network transmission status indicates whether a transmission network used for transmitting data is stable or not in the data transmission process of the sending end device and the receiving end device.
Illustratively, the transmission network may be a WiFi network, such as a dual-frequency wireless WiFi network.
Specifically, the sending end device may start to screen the receiving end device, or may obtain the network transmission state in real time during the screen projection process.
Illustratively, the playing parameters of the receiving end device include resolution, frame rate, and the like supporting playing of video.
For example, a television end may support video playback with a resolution of 4k and a frame rate of 60fps, which may be recorded as a playback capability of 4k @60 fps.
The data parameters of the data to be transmitted may include at least one of the following: frame rate, resolution, contrast, chrominance.
It should be noted that the data parameters of the data to be transmitted include picture parameters when the sending-end device transmits a picture in the screen projection process.
It can be understood that the data parameter of the data to be transmitted and the parameter or parameter value of the original data parameter of the screen projection may be different or the same, and this is not specifically limited in this embodiment of the application.
It should be noted that, under the condition that the data parameter of the data to be transmitted is the same as the parameter of the original data parameter of the screen projection, the specific values of the parameters may be the same or different.
Optionally, under the condition that the network transmission state is not good, the sending end device may adjust a transmission parameter value of the picture to be transmitted according to the playing capability of the receiving end device, so as to reduce the amount of data to be transmitted, for example, at least one of the resolution and the frame rate of the picture to be transmitted is reduced, thereby increasing the playing fluency of the picture to be transmitted.
That is, under the condition that the network state is good, the transmission data amount of the picture after the data parameter of the data to be transmitted is adjusted is larger than that of the picture before the adjustment.
Example 1-1
If in the screen projection process, it is assumed that the sending end device is transmitting a video at 1080p @30fps, and under the condition that the playing capability of the receiving end device is strong, for example, 4k @60fps is supported, if the sending end device detects that the network environment is very stable, the video transmission at 4k @60fps can be supported, the sending end device can adjust the picture data at 1080p @30fps to 4k @60fps through techniques such as super-division frame insertion and the like, and then code transmission is performed to the receiving end device, so that the receiving end device can see the screen projection effect at 4k @60fps, and the screen projection experience is improved.
Optionally, under the condition that the network transmission state is better, the sending end device may adjust the transmission parameter value of the picture to be transmitted according to the playing capability of the receiving end device, and may increase the amount of data to be transmitted, for example, increase at least one of the resolution and the frame rate of the picture to be transmitted, thereby improving the picture quality of the picture to be transmitted.
That is, in the case of a poor network state, the transmission data amount of the picture after adjusting the data parameter of the data to be transmitted is smaller than the transmission data amount of the picture before adjustment.
Examples 1 to 2
If in the screen projection process, it is assumed that the sending end device is transmitting a video at 4k @60fps, if the sending end device detects that the network environment is unstable, for example, the sending end device detects that the network rate cannot meet the current screen projection transmission, at this moment, the receiving end is easy to have a picture stuck and affects the viewing experience after screen projection. The sending end device can reduce the resolution and frame rate of the picture data of 4k @60fps, for example, adjust to 1080p @30fps, reduce the transmitted data amount, and then perform encoding and packaging transmission, thereby avoiding the pause of the receiving end playing caused by network blocking when the network is degraded.
S102, the sending end equipment encodes the data to be transmitted after the data parameters are adjusted to obtain encoded data, and transmits the encoded data to the receiving end equipment.
It should be noted that the data parameter of the data received by the receiving end device is the adjusted data parameter of the data to be transmitted.
Specifically, the receiving end device receives the picture after adjusting the data parameters of the data to be transmitted, and displays the screen projection data on the screen according to the adjusted data parameters.
The embodiment of the application provides a data processing method, firstly, a sending end device adjusts data parameters of data to be transmitted according to at least one of a network transmission state and a playing parameter of a receiving end device; and then, the sending end equipment encodes the data to be transmitted after the data parameters are adjusted to obtain encoded data, and finally, the sending end equipment transmits the encoded data to the receiving end equipment. That is to say, in data transmission, the sending end device may flexibly adjust the data parameters of the data to be transmitted according to the network transmission state and the playing capability of the receiving end device before transmitting the data. For example, in the screen projection process, on one hand, under the conditions of a better network transmission state and strong playing capability of the receiving end device, the picture quality can be improved by adjusting the data parameters of the data to be transmitted, so that the screen projection experience of the picture on the screen of the receiving end device with strong playing capability can be improved under the condition that the sending end device determines that the playing capability of the receiving end device is stronger; on the other hand, under the condition of poor network transmission state, the data transmission amount can be reduced by adjusting the data parameters of the data to be transmitted, and the problem that the display picture of the receiving end is blocked due to network card blockage when the network is poor can be avoided.
Optionally, in the data processing method provided in the embodiment of the present application, the foregoing S101 may specifically be executed through S101 a:
s101a, the sending end device adjusts the value of the data parameter of the data to be transmitted from the first value to the second value according to at least one of the network transmission state and the playing parameter of the receiving end device.
And under the condition that at least one of the network transmission state and the playing parameter of the receiving end meets a first condition, the second value is greater than the first value. And under the condition that at least one of the network transmission state and the playing parameter of the receiving end meets a second condition, the second value is smaller than the first value.
Optionally, at least one of the network transmission status and the play parameter of the receiving end satisfies a first condition, including at least one of the following (1) to (3):
(1) the network transmission rate is greater than a first threshold;
the first threshold may be set by default, or may be set manually by the user as needed.
It should be noted that, in the case that the network transmission rate is greater than the first threshold, it may indicate that the network transmission state is better.
(2) The network transmission rate is greater than the code rate of the data to be transmitted;
it will be appreciated that in the event that the network transmission rate is greater than the code rate of the data to be transmitted, it may be indicated that the network is capable of supporting data transmission at a higher code rate.
(3) The parameter value of the playing parameter of the receiving end is larger than the first numerical value.
It should be noted that, in the case that the parameter value of the playing parameter at the receiving end is greater than the first numerical value of the data parameter of the data to be transmitted, it may be indicated that the playing capability of the receiving end may support playing of data higher than the first numerical value of the data parameter. Namely, the receiving end has stronger playing capability.
Optionally, at least one of the network transmission status and the playing parameter of the receiving end satisfies a second condition, including at least one of the following (4) to (5):
(4) the network transmission rate is less than a second threshold;
the second threshold may be set by default, or may be set manually by the user as needed.
It should be noted that, in the case that the network transmission rate is less than the second threshold, it may indicate that the network transmission status is poor.
It is understood that the first threshold is greater than or equal to the second threshold. The network transmission rate is greater than the first threshold value, which can indicate that the current network state is better and can transmit more data, so that the image quality of the image can be improved first, and the resolution of the image and the frame rate of the video can be increased; the network transmission rate is less than the second threshold, which may indicate that the current network state is poor and there may be a screen projection delay, so that the image quality of the picture may be reduced, and the resolution of the picture and the frame rate of the video may be reduced.
(5) The network transmission rate is less than the code rate of the data to be transmitted;
it will be appreciated that in the case where the network transmission rate is less than the code rate of the data to be transmitted, it may indicate that the network status is poor and network congestion may occur.
(6) The parameter value of the playing parameter of the receiving end is smaller than the first numerical value.
It should be noted that, in the case that the parameter value of the playing parameter at the receiving end is smaller than the first numerical value of the data parameter of the data to be transmitted, it may indicate that the playing capability of the receiving end cannot support the playing of the data with the first numerical value of the data parameter.
Illustratively, whether a picture needs to be adjusted may be calculated according to the code rate of the compressed data of the current picture and the rate of the current WiFi transmission. If the WiFi rate is smaller than the code rate to be transmitted, the current network transmission is blocked, screen projection data cannot be transmitted to receiving end equipment in time, and screen projection is blocked.
For example, assuming that the resolution of a currently transmitted picture is 4k, if the network state is not good, the sending end device may reduce the resolution of the transmitted picture according to the current network load, for example, it is determined that the resolution is 1080p, and the electronic device may adjust the resolution of the picture to be transmitted to be 1080 p. Assuming that the current frame rate of transmission is 60fps, if the network state is not good, the sending end device may reduce the frame rate according to the current network load, for example, it is determined that the frame rate is 30fps, and the sending end device may adjust the frame rate of the picture to be transmitted to be 30 fps.
Similarly, if the resolution of the currently transmitted picture is 1080p, if the network status is better, the sending end device may increase the resolution of the transmitted picture according to the current network load, for example, it is determined that the resolution is 4k, and the sending end device may adjust the resolution of the picture to be transmitted to be 4 k. Assuming that the current frame rate of transmission is 30fps, if the network state is better, the sending end device may increase the frame rate according to the current network load, for example, it is determined that the frame rate is 60fps, and the sending end device may adjust the frame rate of the picture to be transmitted to 60 fps.
Illustratively, the electronic device may increase the frame rate of the video through an interpolation technique and may increase the resolution of the video through a super-resolution technique.
It should be noted that, in the above example, the frame rate and the resolution are respectively adjusted, in practical application, based on the network transmission state and the playing capability of the receiving end device, the frame rate and the resolution may be adjusted at the same time, and after the frame rate and the resolution are adjusted, the sending end device may also adaptively adjust the contrast and the chromaticity, so as to ensure a better display effect.
Based on the scheme, the sending end equipment can judge whether the data parameter of the data to be transmitted needs to be adjusted in real time according to at least one of the network transmission state and the playing parameter of the receiving end equipment; when the first condition is determined to be met, the data parameter of the data to be transmitted needs to be heightened, and when the second condition is determined to be met, the data parameter of the data to be transmitted needs to be lowered, so that the parameter can be adjusted in time according to the network state, the screen projection display effect of the receiving terminal equipment can be flexibly controlled, the definition of the picture can be improved, or the picture blockage caused under the condition that the network condition is poor can be avoided in time.
Optionally, before the foregoing S101, the data processing method provided in this embodiment may further include the following S103 and S104:
s103, under the condition that the screen projection connection is established between the sending end equipment and the receiving end equipment, the sending end equipment acquires at least one of the network transmission state and the playing parameter of the receiving end equipment.
It can be understood that the sending end device may determine the playing capability of the receiving end device, such as the maximum playing frame rate, the maximum supported resolution, and the like of the receiving end device, after the screen-casting connection is established.
S104, the sending end equipment determines the data parameters of the data to be transmitted according to at least one of the network transmission state and the playing parameters of the receiving end equipment and the original data parameters of the transmission picture.
Illustratively, the raw data parameters of the source picture of the transmitting end device may include: frame rate, resolution, contrast, chrominance, dynamic range.
Based on the scheme, after the screen projection connection is established between the sending end equipment and the receiving end equipment, before screen projection data are transmitted, the data parameters of the data to be transmitted are determined based on at least one of the network transmission state and the playing parameters of the receiving end equipment and the original data parameters of the transmission pictures, videos are transmitted based on the data parameters of the data to be transmitted, a group of data parameters suitable for the current network can be flexibly determined according to the current network state, the optimal display effect of the receiving end equipment can be achieved, and the screen projection process experience is better.
Optionally, under the condition that the original data parameter value is high and the network condition is poor, the playing capability of the receiving end device is high, and the original data parameter value is reduced according to the network transmission state.
Optionally, under the condition that the display effect corresponding to the original data parameter is poor, the sending end device may adjust the data parameter according to the playing capability of the receiving end device after the sending end device establishes the screen-casting connection.
Example a: if the parameter of the source picture is SDR and HDR is not supported, the sending end device may perform SDR to HDR on the source picture.
Example b: if the image quality of the source picture is not good, the sending-end device may first adjust the contrast and the chromaticity of the source picture.
Example c: the network environment is very good, the video transmission of 4k @60fps can be supported, the playing capacity of the receiving end equipment is 4k @60fps, the transmitting end screen does not support 4k @60fps, and if the original picture played by the transmitting end screen is a 1080p @30fps video, according to the related technology, after the content displayed on the transmitting end screen is projected to the receiving end equipment with the playing capacity of 4k @60fps, the displayed video which is still 1080p @30fps is displayed, and the watching effect on the screen of the receiving end equipment with the playing capacity of 4k @60fps is poor.
It should be noted that, since the contrast, the chromaticity and the SDR are adjusted to the HDR, the data amount of the picture is less increased, and therefore, the transmitting end device can directly perform the adjustment.
Based on the scheme, if the sending end device detects that the image quality of the source picture is not good before the screen is projected, the image quality can be adjusted first, and then data transmission is performed. For example, in a sending end, if an original video and a game do not support HDR, the contrast and the chromaticity of a source picture cannot display the texture details of a dark region, and the effect of the original picture is not good, so that the picture effect of a screen projected to a receiving end is difficult to improve. In the application, before the picture is sent, the picture quality of the source picture can be adjusted, for example, SDR (standard definition) conversion to HDR (high definition digital) is carried out, so that the display content of the transmitted picture has richer details and tones; the contrast, the chromaticity and the like of the picture are adjusted, so that more hidden textures in dark areas of the picture can be displayed, and the details of bright areas are reserved, so that the display effect of the receiving end equipment can be improved.
For example, a user may control a sending end device to scan through WiFi, search for a receiving end device, after the user determines the receiving end device that establishes a screen-casting connection, the sending end device and the receiving end device first establish a P2P connection through a P2P Protocol, and after the P2P connection is successfully established, the sending end device and the receiving end device may perform RTSP capability negotiation through a Real Time Streaming Protocol (Real Time Streaming Protocol), and then establish a (WiFi Display, WFD) connection based on WiFi.
Generally, after the screen-throwing connection between the sending terminal device and the receiving terminal device is successfully established, when audio and video transmission is started, the sending terminal device captures a source picture, the source picture is encoded and packaged, the packaged data is transmitted to the receiving terminal device through a WiFi network, the receiving terminal device receives the data transmitted by the sending terminal device, then unpacks the data, decodes the data, and finally displays the picture on a screen of the receiving terminal device.
