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.
When sharing the file content through the online conference, the network states of the file content sharing end device and the file content receiving end device affect the transmission quality of the file content more or less. In order to improve the quality of file content sharing, the network bandwidth can be increased, so that the network transmission pressure is relieved, and the transmission quality of the file content is improved.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present application provides a data transmission method, which is applicable to a first device, and the method includes:
step S110: the first device obtains a network state of the second device.
In this embodiment, the first device may be an initiating device for sharing data content, and the second device is a viewing device for sharing data content. For example, when sharing a PPT document remotely, the device presenting the PPT document is the first device and the device viewing the PPT document is the second device. It should be noted that, in some other possible embodiments, the second device may also perform an operation of data content sharing, in this case, the first device may also perform a receiving operation of data content sharing, that is, a relationship between the first device and the second device when performing data content sharing may be relatively transformed. The specific shared data content may be a document (e.g., a PPT document, a report, etc.), a picture, a video, or music, and the specific type may not be limited, and in this embodiment, the data content to be shared may include a plurality of pages to be shared. Optionally, the first device and the second device may be both mobile phones, computers, tablets and other devices with mobile communication functions.
As a mode, the first device and the second device may perform data interaction through the server, in this mode, the first device may send a data content sharing prompt message to the server, where the prompt message may be a conference link, a two-dimensional code, a character string, a screen transmission code, or the like, the data content sharing prompt message is sent to the second device through the server, the second device initiates a data content sharing request to the first device after receiving the data content sharing prompt message, and establishes network connection with the first device through the server after receiving a signal of agreeing to join data content sharing (viewing) returned by the first device. At this time, the second device may report a network state to the server, or report the network state to the server periodically, where the network state may include data such as a packet loss rate, a network delay, and a network jitter, and the server may send the network state of the second device to the first device, so that the first device may adjust a data transmission mode according to the network state of the second device, and the second device may not clearly or completely view shared data content due to network congestion.
As another mode, the first device may also perform network connection with the second device through a short-range wireless communication mode, for example, the first device may perform network connection with the second device through a bluetooth mode, a WiFi mode, and the like, at this time, a distance between the first device and the second device may be a preset distance, a value of the preset distance may be 5 meters, 10 meters, or 50 meters, and the specific value may not be limited. It should be noted that, in this way, data interaction of the network state is performed between the first device and the second device through the server alone, that is, the second device still reports the network state to the server, and then the first device acquires the network state of the second device from the server, where the network state is the network state accessed to the wide area network (or public network). The network state of the second equipment is obtained through the server, and data transmission is carried out in a short-distance wireless communication mode, so that the first equipment can flexibly adjust the data transmission mode to the second equipment according to the network state of the second equipment, and the phenomenon that the watching experience of a user is influenced due to the fact that the data transmission is blocked due to poor network state of the second equipment is avoided.
Step S120: and if the network state does not meet the target condition, acquiring the page to be shared according to a preset acquisition frequency to obtain the image frame corresponding to the page to be shared.
The target conditions may include network delay lower than a first threshold, network jitter lower than a second threshold, and/or packet loss rate lower than a third threshold, and specific values of the first threshold, the second threshold, and the third threshold may not be limited.
In this embodiment, when the network state of the second device is obtained, the first device may determine whether the network state meets a target condition, where the network state meets at least one of a condition that a network delay is lower than a first threshold, a condition that a network jitter is lower than a second threshold, and a packet loss rate is lower than a third threshold, and then may determine that the network state meets the target condition. As a mode, if the network state does not satisfy the target condition, the page to be shared may be acquired according to a predetermined acquisition frequency, and then the image frame corresponding to the page to be shared is obtained. The predetermined acquisition frequency is lower than an original acquisition frequency of the first device for acquiring the page to be shared, for example, the predetermined acquisition frequency may be 1 s/time, and the original acquisition frequency is 500 ms/time. The predetermined capture frequency may be understood as the frequency of screenshots, i.e. the frequency of capturing the entire image frame (or page) content of the screen of the first electronic device.
The method comprises the steps that original acquisition frequencies corresponding to different pages to be shared are different, as one mode, the content complexity of the pages to be shared can be obtained, the original acquisition frequency corresponding to the pages to be shared is determined according to the content complexity, and then the preset acquisition frequency corresponding to the pages to be shared is determined, wherein the higher the content complexity is, the lower the corresponding original acquisition frequency is, and the lower the corresponding preset acquisition frequency is; the lower the content complexity, the higher the corresponding original acquisition frequency and the higher the corresponding predetermined acquisition frequency. In this embodiment, the content complexity may be measured by the number of characters, pictures, videos, and the like included in the page to be shared, for example, the content complexity is higher when the number of characters included in the page to be shared is larger.
It should be noted that the preset acquisition frequency under the above-mentioned condition is always lower than the original acquisition frequency corresponding to the current page to be shared, so that the data volume acquired in a unit time length can be reduced by acquiring the current page to be shared with the preset acquisition frequency lower than the original acquisition frequency corresponding to the current page to be shared, and further, the network transmission pressure is reduced.
It should be noted that, taking the page to be shared as the PPT image as an example, the preset acquisition frequency is higher than the frequency of page turning between different PPT image pages, that is, the speed of acquiring the page to be shared in a unit time length is higher than the speed of switching between different pages to be shared in a unit time length, so that all the pages to be shared of the data content to be shared can be completely intercepted.
In one embodiment, referring to fig. 2, step S120 may include:
step S121: and if the network state does not meet the target condition, acquiring the content type of the page to be shared.
The content types of the pages to be shared are different, and the corresponding transmission rates can be different. In this embodiment, in order to improve the overall definition of the second device viewing the content of the data to be shared, the content type of the page to be shared may be identified when it is determined that the network state of the second device does not satisfy the target condition. Different data contents correspond to different content format identifiers, for example, a picture may include a ". jpg" format identifier, a video may include a "WMV", "AVI", and other format identifiers, and a PPT page may include a ". PPT" or ". pptx", and thus, a content type to which the page belongs may be determined according to the content format identifier of the page to be shared.
Step S122: and if the content type is the designated type, acquiring the page to be shared according to a preset acquisition frequency to obtain the image frame corresponding to the page to be shared.
In this embodiment, the designated type may be a PPT image/page, as an implementation manner, if it is identified that the content type of the page to be shared is the PPT image/page, the page to be shared may be acquired according to a predetermined acquisition frequency to obtain an image frame corresponding to the page to be shared, and then the data amount of the page to be shared acquired in a unit time length may be reduced, so that network transmission pressure during transmission of the page to be shared may be reduced.
Optionally, if the content type of the page to be shared is identified not to be a PPT image/page, the acquisition may be suspended for a period of time, and when the network state of the second device meets the target condition, the page to be shared is acquired according to the original acquisition frequency of the page to be shared by the first device, or if the network state of the second device is better, the page to be shared may be acquired with an acquisition frequency higher than the original acquisition frequency, so as to increase the data amount of the page to be shared acquired in a unit time length, and further improve the fluency of the second device in viewing the page to be shared.
It should be noted that the description of the specified type is only described as an example, and in actual implementation, the specified type may be not only a PPT image/page, but also other data content types, which is not described in detail herein.
In another embodiment, referring to fig. 3, step S120 may include:
step S123: and determining the data receiving rate of the second equipment according to the network state.
As a manner, the first device may determine the data receiving rate of the second device according to the network state of the second device, for example, the data receiving rate of the second device may be calculated according to the network delay, the network jitter, or the packet loss rate of the second device.
Step S124: and if the data receiving rate is lower than a preset threshold value, judging that the network state does not meet the target condition, and acquiring the page to be shared according to a preset acquisition frequency to obtain an image frame corresponding to the page to be shared.
The preset threshold is a critical value for smooth transmission (that is, phenomena such as blockage and picture loss do not exist) of the page to be shared, and the specific numerical value can be set according to actual needs, so that if the data receiving rate of the second device is lower than the preset threshold, it can be determined that the network state does not meet the target condition, the page to be shared can be acquired according to a preset acquisition frequency, and an image frame corresponding to the page to be shared is obtained.
Step S130: and coding the image frame to obtain a data stream to be transmitted.
In this embodiment, the obtained image frame may be encoded according to an encoding frequency adapted to a predetermined acquisition frequency, so as to obtain a data stream to be transmitted. For example, the predetermined acquisition frequency is increased and the corresponding encoding frequency may be increased, while if the predetermined acquisition frequency is decreased, the corresponding encoding frequency may be decreased and the amplitude of the increase or decrease adapted.
Step S140: and transmitting the data stream to be transmitted to the second equipment at a specified transmission rate.
The specified transmission rate is to transmit only one frame of key frame data stream within a specified time duration, for example, one frame is transmitted within 1 second, one frame is transmitted within 3 seconds, or one frame is transmitted within 5 seconds. Optionally, the number of the second devices may be one or more, and if the number of the second devices is one, the data stream to be transmitted may be transmitted to the second devices according to a fixed transmission rate; if the number of the second devices is multiple, if the network states of the multiple second devices are different, the data stream to be transmitted may be transmitted to the corresponding second devices at the respective designated transmission rates corresponding to the multiple second devices, and if the designated transmission rates corresponding to the second devices in different network states are different, the network state is better, the higher the corresponding designated transmission rate is, the weaker the network state is, and the lower the corresponding designated transmission rate is.
According to the data transmission method, the network state of the second equipment is obtained through the first equipment, then if the network state does not meet the target condition, the page to be shared is collected according to the preset collection frequency, the image frame corresponding to the page to be shared is obtained, the preset collection frequency is lower than the original collection frequency of the page to be shared, the image frame is coded again, the data stream to be transmitted is obtained, and then the data stream to be transmitted is transmitted to the second equipment at the appointed transmission rate. Therefore, the method and the device have the advantages that under the condition that the network state of the second device does not meet the target condition, the page to be shared is acquired according to the preset acquisition frequency lower than the original acquisition frequency of the first device for acquiring the page to be shared, so that the image frames with relatively reduced number can be obtained, the network transmission pressure can be reduced when the data stream to be transmitted, which is obtained after the image frames are coded, is transmitted, the problem that the picture content cannot be seen clearly due to the fact that the playing picture of the file content in the second device is lost due to the fact that the transmission is blocked when the network state is not good can be solved, and the user viewing experience of the second device is improved.
Referring to fig. 4, another embodiment of the present application provides a data transmission method, which can be applied to a first device, the method including:
step S210: the first device obtains a network state of the second device.
Step S220: and if the network state does not meet the target condition, acquiring the page to be shared according to a preset acquisition frequency to obtain the image frame corresponding to the page to be shared.
Step S230: and coding the image frame to obtain a data stream to be transmitted.
Step S240: and determining the data receiving rate corresponding to each of the at least one second device according to the network state of the at least one second device.
In this embodiment, the first device may determine the data receiving rate of the second device according to the network delay, the network jitter, or the packet loss rate of the second device.
Step S250: and determining data sending periods respectively corresponding to the at least one second device according to the data receiving rate.
In this embodiment, the number of the second devices is at least one.
The second device with the higher data receiving rate receives the page to be shared more quickly, and the second device with the lower data receiving rate receives the page to be shared more slowly. In order to optimize the problem of data loss in the data transmission process caused by poor network environment of the second device and optimize the problem of network congestion caused by excessive data, the embodiment may determine the data sending period corresponding to each of the at least one second device according to the data receiving rate of the second device to the page to be shared. Specifically, the larger the data receiving rate, the shorter the data transmission period, and the smaller the data receiving rate, the longer the data transmission period. For example, if the second device corresponds to a data receiving rate of 1 frame/second, the corresponding data transmission period may be 800 milliseconds, and if the second device corresponds to a receiving rate of 2 frames/second, the corresponding data transmission period may be 200 milliseconds.
Step S260: and transmitting the data stream to be transmitted to at least one second device according to the respective corresponding data transmission periods.
In this embodiment, the update frequency of the page to be shared may be fixed or may also be variable.
If the update frequency is fixed, the data stream to be transmitted may be transmitted to at least one of the second devices according to the respective corresponding data transmission periods. And if the update frequency is changed, the update frequency of the page to be shared can be acquired, the data sending period corresponding to at least one second device is adjusted according to the update frequency, and the data stream to be transmitted is transmitted to at least one second device according to the adjusted data sending period corresponding to at least one second device. In this embodiment, the faster the update frequency changes, the faster the data transmission period changes.
In a specific application scenario, the data transmission period may be adjusted according to a change of the update frequency. For example, if the data receiving rate corresponding to the second device is 1 frame/second, the corresponding data sending period may be 800 milliseconds, and at this time, if the switching duration of the page to be shared from the previous page to the current page is 600 milliseconds, the data sending period corresponding to the second electronic device may be adjusted (reduced here) to 400 milliseconds, or adjusted to any value less than 600 milliseconds, that is, the data sending period is less than the switching duration of the page to be shared from the previous page to the current page, so that the content of the page to be shared can be completely collected, and no page to be shared is missed. Similarly, if the data receiving rate corresponding to the second device is 20 frames/min, the corresponding data sending period may be 300 milliseconds, and at this time, if the switching duration of switching the page to be shared from the previous page to the current page is 700 milliseconds, the data sending period corresponding to the second electronic device may be adjusted (increased here) to 500 milliseconds, so that under the condition that the switching duration is long and the data receiving rate is high, the pressure of network transmission is reduced by prolonging the data sending period, and thus the definition and the picture quality of the page to be shared viewed by the second device can be improved.
It can be understood that when the content of the page to be shared is more, if the transmission is faster, network transmission congestion may be caused due to poor network state of the second device, and when the content of the page to be shared is less, if the transmission is slower, the content of the playing picture in the second device may be lost or stuck.
The higher the content complexity is, the higher the corresponding update frequency is, the longer the data transmission period is (that is, the higher the content complexity is, the lower the transmission frequency between the first device and the second device is), the lower the content complexity is, the corresponding update frequency is, the longer the data transmission period is (that is, the lower the content complexity is, the higher the transmission frequency between the first device and the second device is), so that the transmission frequency between the first device and the second device is flexibly determined according to the content complexity of the page to be shared, and the network transmission pressure caused by too fast transmission when the network state is not good is avoided.
The sending time length in the page to be shared can be estimated according to the content complexity, and the data sending period is adjusted according to the number of characters, pictures or videos in the page to be shared and the corresponding sending time length.
For example, in a specific application scenario, if the current page to be shared includes 200 characters and two pictures, the estimated sending time is 300 milliseconds, and if the data receiving rate corresponding to the second device is 1 frame/second, and the switching time for switching the page to be shared from the previous page to the current page is 600 milliseconds, the data sending period corresponding to the second electronic device may be adjusted from the original 400 milliseconds (assuming that the original sending period determined according to the foregoing manner is 400 milliseconds) to 500 milliseconds. Similarly, if the current page to be shared includes 20 characters and 1 picture, the estimated sending time is 200 milliseconds, and if the data receiving rate corresponding to the second device is 1 frame/second, and the switching time for switching the page to be shared from the previous page to the current page is 600 milliseconds, the data sending cycle corresponding to the second electronic device may be adjusted from the original 400 milliseconds (assuming that the original sending cycle determined according to the foregoing manner is 400 milliseconds) to 100 milliseconds.
As another embodiment, the data sending period corresponding to each of the at least one second device may be adjusted by the content size of the page to be shared according to the update frequency of the page to be shared and the data receiving rate. At this time, if the updating frequency is slower and the data receiving rate is slower, if the content size is smaller, the corresponding data sending period is shorter; and if the content size is larger, the corresponding data transmission period is longer. It should be noted that the value of the data sending period in this embodiment is smaller than the value corresponding to the update frequency of the page to be shared.
According to the data transmission method, a network state of second equipment is obtained through first equipment, then if the network state does not meet a target condition, a page to be shared is acquired according to a preset acquisition frequency, an image frame corresponding to the page to be shared is obtained, the preset acquisition frequency is lower than an original acquisition frequency of the first equipment for the page to be shared, the image frame is encoded again, a data stream to be transmitted is obtained, then a data receiving rate corresponding to each of at least one second equipment is determined according to the network state of the at least one second equipment, a data sending period corresponding to each of the at least one second equipment is determined according to the data receiving rate, and the data stream to be transmitted is transmitted to the at least one second equipment according to the data sending period corresponding to each of the at least one second equipment. The method realizes that the data sending period for transmitting the data stream to be transmitted can be flexibly adjusted according to the network state of the second electronic equipment, and then the data can be pertinently transmitted according to the network state of the opposite terminal equipment when the data content is shared, so that network congestion caused by excessive data transmission when the network state of the second equipment is not good can be avoided, and the problem of poor file content playing definition of the second equipment caused by the poor network state is also avoided.
