detailed description

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

The data downloading method provided in this application can be applied to the implementation environment as shown in FIG. 1 . The terminal 102 communicates with the server 104 through the network. The terminal 102 may be a personal computer, a notebook computer, a media player, a smart TV, a smart phone, a tablet computer, a portable wearable device, or the like, and the embodiment of the present application does not specifically limit the type of the terminal 102 . The server 104 may be a single server, or a server cluster composed of multiple servers, and the server 104 may be a tower server, a rack server, a blade server, a high-density server, a single-socket server, a dual-socket server, or a multi-socket server. Servers, etc., the embodiment of the present application does not specifically limit the type of the server 104 .

In one embodiment, as shown in FIG. 2 , a data download method is provided, and the method is applied to the terminal in FIG. 1 as an example for description, including the following steps:

Step S100, the terminal obtains an average download rate according to the data volume and download duration of the downloaded multimedia data.

In this embodiment of the present application, the multimedia data may include video data and/or picture data, and the video data may be, for example, drama videos, live videos, short videos, etc., and the picture data may be pictures in various formats.

In a possible implementation manner of step S100, after the multimedia data download is completed, the terminal may obtain the total data volume of the downloaded multimedia data and the total download duration for downloading the multimedia data, and then divide the total data volume by the total data volume. Download time, then get the average download rate.

In another possible implementation manner of step S100, the terminal may also acquire a dynamic average download rate in the process of downloading the multimedia data. For example, the terminal can set a time window, the length of the time window is fixed, and the length of the time window can be set by itself during the implementation; the terminal can move the time window periodically during the downloading process of multimedia data, such as moving once per second, every time it moves time window, the terminal calculates the sum of the download data volume in the current time window once, and then divides the total download data volume in the current time window by the length of the time window to obtain the dynamic average download rate in the current time window.

In the process of downloading multimedia data, the dynamic average download rate corresponding to the last time window calculated by the terminal is the average download rate obtained by the terminal in step S100.

In another possible implementation manner of step S100, the way for the terminal to obtain the dynamic average download rate may also be implemented by setting a data amount window. The data volume corresponding to the data volume window is fixed. For example, the data volume window is set to be fixed at 900K. During the multimedia data download process, the terminal can calculate the download data volume and download rate at each time interval according to preset time intervals. Each time the terminal calculates the download data volume and download rate of the current time interval, it corresponds to sliding the data volume window once, and the sliding data volume window includes the latest calculated data of the terminal; the terminal detects the downloaded data volume in the sliding data volume window. Whether the sum exceeds the data volume corresponding to the data volume window (for example, 900K), if it exceeds, the terminal will remove the longest downloaded data volume in the data volume window, so as to keep the sum of the downloaded data volume in the data volume window not exceeding 900K; the terminal calculates the average value of each download rate in the excluded data volume window, and then obtains the dynamic average download rate corresponding to the data volume window.

In the process of downloading multimedia data, the dynamic average download rate corresponding to the last data volume window calculated by the terminal is the average download rate obtained by the terminal in step S100.

This embodiment does not specifically limit the manner in which the terminal obtains the average download rate according to the data volume and download duration of the downloaded multimedia data.

In this embodiment of the present application, the downloaded multimedia data may be the multimedia data downloaded by the terminal most recently, and the terminal obtains an average download rate according to the data volume and download duration of the downloaded multimedia data, and the average download rate is the average download rate of the downloaded multimedia data in The average download rate during the download process can be used to approximately characterize the current network download environment quality of the terminal. In a possible implementation manner, the time difference between the download end time and the current time of the downloaded multimedia data may be less than a preset threshold, and the smaller the time difference, the more the average download rate obtained by the terminal is closer to the current Actual network download environment quality.

Step S200, the terminal searches the preset mapping table for the target data quality parameter matching the average download rate.

In the embodiment of the present application, a mapping table is preset in the terminal, and the mapping table represents the corresponding relationship between the download rate and the data quality parameter, wherein the data quality parameter represents the definition of multimedia data. As an embodiment, in the case that the multimedia data includes video data, the data quality parameter includes a video bit rate, and in the case that the multimedia data includes picture data, the data quality parameter includes the picture resolution.

In a possible implementation manner, the mapping table may include the correspondence between each download rate interval and the data quality parameter. For example, taking the multimedia data as video data and the data quality parameter as the video bit rate as an example, the mapping table may Including the video bit rate corresponding to the download rate interval 100k/s-500k/s is 500kbps, the video bit rate corresponding to the download rate interval 500k/s-1000k/s is 1000kbps, and the video bit rate corresponding to the download rate interval greater than 1000k/s is 2000kbps.

The terminal searches the preset mapping table for the target data quality parameter that matches the average download rate, and may first search the mapping table for the download rate interval that matches the average download rate, and then, according to the determined download rate interval, finds the target data quality parameter in the mapping table. Search for the video bit rate corresponding to the download rate interval in the download rate range, and then obtain the target data quality parameter.

It should be noted that, in other embodiments, the mapping table represents the form of the corresponding relationship between the download rate and the data quality parameter, and it may also be that different download rates correspond to different data quality parameters, which is not specifically limited here.

Step S300, the terminal determines a target download address corresponding to the target data quality parameter from multiple download addresses, and downloads the corresponding target multimedia data based on the target download address.

In the embodiment of the present application, the definition of multimedia data corresponding to each download address is different. For example, taking the multimedia data as video data as an example, the video data A corresponds to four download addresses, which are respectively used for downloading files whose definition is "stream-saving". Video data A, video data A with a resolution of "HD", video data A with a resolution of "Ultra-Definition", and video data A with a resolution of "Blu-ray".

In this embodiment of the present application, the multiple download addresses may be requested by the terminal from the server after detecting that the user has entered multimedia software, such as multimedia software such as live broadcast software, video playback software, etc.

As an implementation manner, for each uploaded multimedia data, such as video data, the server will transcode it into a multi-bit rate video and store it under different download addresses. If receiving the address of the terminal requesting multimedia data, the server will deliver multiple download addresses corresponding to the multimedia data, and deliver a mapping comparison table including the correspondence between each download address and each data quality parameter.

The terminal can look up the download address corresponding to the target data quality parameter according to the mapping comparison table, and then obtain the target download address. After the terminal determines the target download address, the terminal downloads the corresponding target multimedia data from the target download address, and thus the obtained target multimedia data is multimedia data with a definition matching the average download rate.

For example, the terminal obtains the average download rate according to the data volume and download duration of the downloaded multimedia data. If the average download rate is small, it indicates that the current network download environment quality of the terminal is poor, and the terminal selects the target multimedia data with low definition. If the average download rate is high, it indicates that the current network download environment quality of the terminal is good, and the terminal selects the target multimedia data with high definition to download.

In this embodiment, the average download rate is obtained according to the data volume and download duration of the downloaded multimedia data, and the average download rate is used to characterize the current network download environment quality of the terminal; then, in the mapping representing the correspondence between the download rate and the data quality parameters In the table, find the target data quality parameter that matches the average download rate, and the data quality parameter represents the clarity of the multimedia data; then, determine the target download address corresponding to the target data quality parameter from multiple download addresses, and each download address The definition of the corresponding multimedia data is different, that is, the target download address that matches the current network download environment quality of the terminal is determined from the multiple download addresses, and the corresponding target multimedia data is downloaded based on the target download address, that is, the terminal is obtained. The current network downloads the target multimedia data with the resolution matching the quality of the environment, so that the resolution of the multimedia data to be downloaded can be selected according to the average download rate of the downloaded multimedia data.

For example, in the case that the average download rate is low, that is, the current network download environment quality of the terminal is poor, by selecting the target data quality parameter matching the current average download rate and determining the matching target download address, the download clarity can be achieved. lower target multimedia data; and in the case where the average download rate is higher, that is, the current network download environment quality of the terminal is better, similarly, the target multimedia data with higher definition can be downloaded; this avoids the traditional technology. , the terminal downloads high-definition multimedia data by default and displays it to the user, and downloading high-definition multimedia data even when the quality of the terminal network download environment is not good may easily lead to the problems of slow playback and slow loading of the multimedia data.

In this embodiment of the present application, by selecting a matching target download address according to different average download rates to download the target multimedia data of the corresponding definition, the situation that the playback of multimedia data is stuck and the loading is slow can be alleviated, so that the multimedia data of the terminal can be improved. display effect.

In one embodiment, based on the above-mentioned embodiment shown in FIG. 2 , this embodiment relates to the process of how the terminal obtains the average download rate according to the data amount and download duration of the downloaded multimedia data. As shown in FIG. 3, in this embodiment, step S100 includes S101, step S102 and step S103:

Step S101: During the process of downloading the multimedia data, the terminal acquires download information corresponding to each time interval according to a preset time interval.

In this embodiment of the present application, the time interval may be fixed or variable. For example, a fixed time interval of 1s may be used as a time interval, or the time interval may be set to be 5s, 2s, 1s, 3s, 5s, and so on. There is no specific restriction here.

In a possible implementation manner of step S101, referring to FIG. 4, the terminal may implement the process of step S101 by executing step S1011, step S1012 and step S1013 as shown in FIG. 4:

Step S1011, the terminal acquires the first download data volume at the start time of each time interval and the second download data volume at the end time.

For each time interval, the terminal may detect the first downloaded data amount at the start time of the time interval and the second downloaded data amount at the end time of the time interval. As an implementation manner, since in the process of downloading multimedia data, each time interval is continuous, the terminal may collect the amount of downloaded data once at the termination time of each time interval.

Step S1012, the terminal takes the difference between the second download data amount and the first download data amount as the download data amount of the time interval.

For each time interval, the terminal subtracts the first downloaded data volume at the start time of the time interval from the second downloaded data volume at the termination time corresponding to the time interval, and the first downloaded data volume is also the previous time interval The download data volume at the termination time of , thus, the download data volume corresponding to the time interval is obtained.

Step S1013, the terminal calculates the download rate corresponding to each time interval according to the download data amount of each time interval and the duration of the corresponding time interval.

The terminal divides the download data volume of the time interval by the duration of the time interval to obtain the download rate corresponding to the time interval. For example, if the download data volume corresponding to a certain time interval is 500k, and the duration of the time interval is 5s, then The download rate corresponding to this time interval is 100k/s.

Therefore, in the process of downloading multimedia data, the terminal obtains the download information of the current time interval once at the termination time of each time interval.

Step S102, the terminal determines at least one target download information from the download information according to the download data amount included in the download information.

It can be understood that, in the process of downloading the downloaded multimedia data, the download rate closer to the current moment is closer to the actual download rate at the current moment. In the download information corresponding to each time interval, the terminal determines the download information closest to the current moment as the target download information, or determines a plurality of continuous download information closest to the current moment as the target download information. The at least one target download information obtains an average download rate that is closer to the current actual network download environment quality of the terminal.

In a possible implementation manner, referring to FIG. 5 , the terminal may implement the process of step S102 by performing steps S1021 , S1022 , S1023 and S1024 as shown in FIG. 5 :

Step S1021, the terminal sequentially traverses the download data volume included in each download information by using a preset data volume window in the order of the acquisition time of each download information from early to late.

The data volume corresponding to the data volume window is fixed. For example, if the data volume window is set to 900K, the terminal slides the data volume window once every time the terminal calculates the download information for a time interval. The sliding data volume window includes the latest download information calculated by the terminal.

For example, in the process of downloading multimedia data, the download information corresponding to the first five time intervals is (500k, 100k/s), (400k, 200k/s), (300k, 300k/s), (600k, 200k/s) in sequence. s), (500k, 100k/s), after the download information (500k, 100k/s) of the first time interval is calculated, the terminal slides the data volume window once, and the sliding data volume window includes the download information ( 500k, 100k/s), after the download information (400k, 200k/s) of the second time interval is calculated, the terminal slides the data volume window once again, and the sliding data volume window includes the download information (500k, 100k/s) and (400k, 200k/s).

Step S1022, each time the terminal traverses the download data amount included in a piece of download information, it detects whether the sum of the traversed download data amounts exceeds the data amount window.

Each time the terminal slides the data volume window, it detects whether the sum of the traversed downloaded data volume exceeds the data volume window, that is, detects whether the sum of the download data volume of each download information included in the data volume window exceeds the data volume corresponding to the data volume window. For example, it is detected whether the sum of the download data amount of each download information included in the data amount window exceeds 900k.

For example, after the download information (400k, 200k/s) of the second time interval is calculated, the terminal slides the data volume window once again, and the sliding data volume window includes the download information (500k, 100k/s) and ( 400k, 200k/s), the sum of the downloaded data volume is 900k, which does not exceed the data volume window. However, after the calculation of the download information (300k, 300k/s) in the third time interval, the terminal slides the data volume window again. , the sum of the downloaded data volume in the sliding data volume window is 500k+400k+300k=1200k, which exceeds the set data volume window by 900k.

Step S1023, if it exceeds, the terminal removes at least one download information with the earliest acquisition time among the traversed download data volumes.

If it is detected whether the sum of the traversed downloaded data volume exceeds the data volume window, the terminal will sequentially remove one or more download information exceeding the data volume window in the order of the acquisition time of the download information from early to late, so as to maintain the data volume The sum of the download data of each download information in the window does not exceed 900k.

Step S1024, the terminal determines the download information retained after the traversal is completed as the target download information.

The terminal determines the download information retained after the traversal is completed as the target download information. For example, if the last download information is retained after the traversal is completed, the last download information is determined as the target download information, or the last two download information are retained after the traversal is completed. , the terminal determines that the last two download information are two target download information.

Step S103, the terminal obtains an average download rate based on the download rate included in the download information of each target.

In a possible implementation, if the data volume window includes multiple download information after the traversal is completed, that is, multiple target download information is determined, the terminal can calculate the average value of the download rates included in each target download information to obtain the average download information. rate.

In other embodiments of the present application, if the data volume window includes a piece of download information after the traversal is completed, that is, the terminal determines a target download information, the download rate included in the target download information is the average download rate obtained by the terminal. make specific restrictions.

In the embodiment of the present application, the data volume window terminal can be implemented in the form of creating an array, so as to realize the collection of new download information and the discarding of old download information exceeding the data volume window.

In this embodiment of the present application, the average download rate in the data amount window is dynamically obtained during the downloading process of the downloaded multimedia data through a preset data amount window, and the average download rate in the last data amount window is determined as the average download rate , since the download time of the download data volume corresponding to the last data volume window is closest to the current time, the average download rate obtained based on the last data volume window can more approximately characterize the current network download environment quality of the terminal; and based on the last data volume window Obtaining the average download rate from the download rate included in the download information of each target in the data volume window is beneficial to avoid errors caused by a sudden change in a single download rate, thereby improving the accuracy of the average download rate, and is conducive to the download based on the average download rate and the current terminal's current rate. The network downloads the target multimedia data whose environmental quality is more matched.

In one embodiment, on the basis of the above-mentioned embodiment shown in FIG. 2 , step S100 may include step A:

Step A: Under the condition that the preset trigger condition is met, obtain the average download rate according to the data volume and download duration of the downloaded multimedia data;

The trigger condition includes any of the following:

The terminal detects the video playback instruction for the first time within the preset time period;

The terminal detects the video playback instruction for the target live room for the first time within the preset time period;

The terminal detects a video preloading operation;

The terminal detects an image loading operation.

In the embodiments of the present application, different trigger conditions may correspond to different application scenarios. The following will describe the implementation process of the data downloading method according to the embodiment of the present application in conjunction with some application scenarios of the data downloading method according to the embodiment of the present application.

In one embodiment, taking a video playback scenario as an example, in traditional video playback, when the user does not select a definition, the terminal downloads high-definition video data by default and plays it, but when the quality of the terminal network download environment is poor It often leads to slow downloads and video freezes, which seriously affects the user's viewing experience and is not conducive to improving user stickiness.

In this embodiment, if the terminal detects the video playback instruction for the first time within a preset time period, the average download rate is obtained according to the data volume and download duration of the downloaded video data. The video playback instruction may be input to the terminal by the user. The time period may be, for example, one day or several hours, which is not specifically limited here.

After the terminal detects the video playback instruction for the first time within the preset time period, it needs to play the video data specified by the user, and the terminal downloads the video data with the default definition, and in the process of downloading the video data, according to The data volume and download duration of the downloaded video data get the average download rate. The specific implementation manner in which the terminal obtains the average download rate according to the data amount and download duration of the downloaded video data refers to the above-mentioned embodiment, and details are not repeated here.

The terminal searches the preset mapping table for a target video bit rate matching the average download rate according to the average download rate, and the target video bit rate is used as the video bit rate used by the terminal to download the second video data.

When the terminal downloads the second video data, for example, the user inputs the video playback instruction again, or when the terminal detects that the current video data is played and needs to automatically play the next video data, the terminal downloads the second video data from multiple downloads corresponding to the second video data. The target download address corresponding to the target video bit rate is determined in the address, and the target video data (ie the second video data) having the target video bit rate is downloaded from the target download address.

Further, in the process that the terminal downloads the second video data, the terminal continues to obtain the average download rate according to the data volume and the download duration of the downloaded video data in the second video data download process, and then searches the mapping table for corresponding The target video bit rate, so as to determine the download address for downloading the third video data with the target video bit rate, and so on. Therefore, it is realized that the video bit rate of the next video data, that is, the definition, is selected according to the average download rate of the previous video data, which can alleviate the situation that the video data is stuck and loaded slowly, so that the video of the terminal can be improved. Data display effect.

In a possible implementation manner, the interval between the download end time and the download start time of adjacent video data is less than a preset threshold, for example, the download end time of the first video data and the download start time of the second video data The interval between times is less than the preset threshold, the interval between the download end time of the second video data and the download start time of the third video data is less than the preset threshold, etc., thus avoiding the time interval of adjacent video data If it is too large, the average download rate of the previous video data may be quite different from the actual network download environment quality of the terminal when the next adjacent video data is downloaded.

In one embodiment, taking a live broadcast scenario as an example, in traditional live broadcast, the terminal downloads high-definition live video data by default and plays it. In an environment where the quality of the terminal network download environment is not good, it often leads to slow download and live video cards. The problem of pauses seriously affects the viewing experience of users and is not conducive to improving user stickiness.

In this embodiment, if the terminal detects the video playback instruction for the target live broadcast room for the first time within a preset time period, in the process of downloading the live video data, the average download is obtained according to the data volume and download duration of the downloaded live video data. rate, the video playback instruction may be input to the terminal by the user, and the preset time period may be, for example, several hours, etc., which is not specifically limited here.

Referring to FIG. 6, FIG. 6 is a schematic diagram of an interface corresponding to a switching operation between live broadcasts in one embodiment. When the terminal monitors the switching operation of the user switching between live broadcasts (for example, the user slides up the interface), the terminal needs to download the second live video data and display it on the interface after sliding. The terminal then determines the target download address corresponding to the target video bit rate from the multiple download addresses corresponding to the second live video data, and downloads the target live video data with the target video bit rate from the target download address (that is, the second live video data).

Further, in the process that the terminal downloads the second live video data, the terminal continues to obtain the average download rate according to the data volume and download duration of the second downloaded live video data, and then searches the mapping table for the corresponding target video code. rate, so as to determine the download address for downloading the third live video data with the target video bit rate, and so on. In this way, the video bit rate of the next live video data, that is, the definition, can be selected according to the average download rate of the previous live video data, which can alleviate the situation that the playback of live video data is stuck and the loading is slow, so that the terminal can be improved. The display effect of the live video data. In addition, in this embodiment, when the user is watching the current live video data, the definition of the live video data will not change, and the next live video data will be changed according to the average download rate, which can avoid constantly switching the definition. The problem of poor user viewing experience is caused, so that the user experience can be improved, which is beneficial to increase the daily activity of users.

In one embodiment, taking a video preloading scenario as an example, in traditional video preloading, the terminal uses the same video bit rate to preload each preloaded video data. In an environment where the quality of the terminal network download environment is poor, it is often Problems causing slow preloading.

In this embodiment, when the terminal detects a video preloading operation, in the preloading process, the average download rate is obtained according to the data amount and download duration of the downloaded video data. During the first video preloading process, the terminal can use the default definition to load video data, and during the video data loading process, obtain the average download rate according to the data volume and download duration of the downloaded video data. The specific implementation manner in which the terminal obtains the average download rate according to the data amount and download duration of the downloaded video data refers to the above-mentioned embodiment, and details are not repeated here.

The terminal searches the preset mapping table for a target video bit rate matching the average download rate according to the average download rate, and the target video bit rate is used as the video bit rate corresponding to the terminal loading the second video data. When the terminal needs to load the second video data, for example, the terminal may detect that the previous video data is loaded, and then determine the target download address corresponding to the target video bit rate from the multiple download addresses corresponding to the second video data, Download the target video data (ie, the second video data) with the target video bit rate from the target download address.

Further, in the process that the terminal loads the second video data, the terminal continues to obtain the average download rate according to the data volume and the download duration of the second downloaded video data, and then looks up the corresponding target video bit rate in the mapping table, Thereby, the download address for downloading the third video data with the target video bit rate is determined, and so on. Therefore, the video bit rate of the next video data to be loaded, that is, the definition, can be selected according to the average download rate of the last loaded video data, which can alleviate the problem of slow terminal preloading and improve terminal video preloading. speed.

In one embodiment, taking a picture loading scenario as an example, in the traditional picture loading, the terminal uses the same picture resolution to download each picture. In an environment where the quality of the terminal network download environment is not good, the picture download is likely to be slow, and the user views the picture. Bad experience.

In this embodiment, when the terminal detects a picture loading operation, in the picture downloading process, the average download rate is obtained according to the data amount and download duration of the downloaded picture data. In the process of downloading the picture data for the first time, the terminal can download the picture data with the default definition (that is, the picture resolution), and in the process of downloading the picture data, the average download is obtained according to the data volume and the download time of the downloaded picture data. rate. The specific manner in which the terminal acquires the average download rate according to the data amount and download duration of the downloaded picture data is similar to the manner in which the average download rate of the video data is acquired in the foregoing embodiment, and will not be repeated here.

The terminal searches the preset mapping table for a target picture resolution matching the average download rate according to the average download rate, and the target picture resolution is used as the picture resolution used by the terminal to download the second picture data. When the terminal needs to load the second image data, for example, the terminal detects the image loading operation again, determines the target download address corresponding to the resolution of the target image from the multiple download addresses corresponding to the second image data, and downloads the image from the target. The address downloads the target picture data (ie the second picture data) with the target picture resolution.

As an implementation manner, for each uploaded picture data, the server will transcode it into pictures of different resolutions and store them under different download addresses. If the terminal requests the address of a picture data, the server will deliver multiple download addresses corresponding to the picture data, and deliver a mapping table including the correspondence between the download addresses and the resolutions of the pictures for the terminal to distinguish according to the target picture rate to find the corresponding target download address.

Further, in the process of loading the second picture data by the terminal, the terminal continues to obtain the average download rate according to the data amount and the download duration of the downloaded second picture data, and then looks up the corresponding target picture resolution in the mapping table, Thereby, the download address for downloading the third picture data with the target picture resolution is determined, and so on. Thus, the image resolution of the next image data that needs to be loaded, that is, the clarity, is selected according to the average download rate of the last downloaded image data, which can alleviate the problem of slow loading of terminal images, thereby improving the speed of image loading. , improve the user experience, and help increase the daily activity of users.
