Wherein, the above-mentioned starting download time is located before the loading time of the playback resource, and is determined according to the download duration of the playback resource. The above download duration indicates the duration required to download the playback resources at the current network speed. In this way, the playback resources are downloaded from the initial download time, which can effectively ensure that the playback resources are downloaded to the local when the loading time is reached, so that the playback resources can be downloaded at the loading time. Directly load the playback resources that have been downloaded to the local, reduce the situation of waiting for the playback resources to be downloaded during the video playback process, and further improve the timeliness of video playback.

The following first introduces several concepts involved in the embodiments of the present disclosure.

The "video playback process" mentioned in the embodiments of the present disclosure may be a process of playing a video that requires interaction with a user during the playback process, or a process of playing a video that requires updating auxiliary information during the playback process. The above auxiliary information refers to information that assists in completing the video playback, for example, the video title, background picture, background music, and the like.

In view of the above situation, resources such as resources for interacting with the user, video titles, background pictures, background music and other resources need to be loaded during the video playback process. In the embodiments of the present disclosure, the above-mentioned resources are referred to as playback resources.

In an embodiment of the present disclosure, the above-mentioned video playing process can be divided into a process of playing a live video and a process of playing a recorded video. In this way, it can be considered that the modes of video playback include: live mode and recording mode.

The application scenarios of the solutions provided by the embodiments of the present disclosure will be described below.

The solutions provided by the embodiments of the present disclosure are applied to video playback scenarios, for example, course video playback scenarios, shopping video playback scenarios, and the like.

In the video playback scenario, the client obtains data related to video playback from the server, and displays the playback video to the user according to the obtained data. During video playback, the client needs to load various playback resources.

As can be seen from the foregoing, there may be different modes of video playback, and the mode of video playback may be a recording mode or a live mode. In the recording mode, the video played during the video playback is a pre-recorded video, also called a recorded video. In the live mode, the video played during the video playback is real-time recorded video, also known as live video.

During the video playback, in addition to playing the video, various resources can be displayed or played to the user, and these resources are playback resources. Playback assets include interactive and non-interactive assets. Among them, the interactive resource is a resource that guides users to participate in the play interaction, and the interactive resource can enhance the play interactivity and increase the frequency of the user's participation in the play interaction. For example, the interactive resources may include: interactive game resources, interactive question-and-answer resources, interactive virtual animation character resources, and the like. Corresponding to interactive resources, non-interactive resources cannot guide users to participate in playback interaction, but non-interactive resources can be used to enhance playback fun and attract users to watch playback. For example, non-interactive resources may include: background images, background music, video titles, and other resources.

The following describes specific application scenarios.

1. Course video playback scene

Suppose, the playback resources include: interactive game resources, background pictures and background music.

Case 1: The video playback mode is: recording mode.

Since the video played in this case is a pre-recorded course video, the course content played at each moment during the playback process is determined, and the course content determines the loading time of each playback resource. Therefore, the loading time of each playback resource is pre-recorded. It is determined that the predetermined loading time is the actual loading time of the playback resource.

During the video playback process, when the loading time of each playback resource is reached, the playback resource starts to be loaded. Therefore, in the recording and playback mode, the triggering condition for the loading of the playback resources is: the preset loading time of the playback resources is reached during the video playback process.

For example, the loading time of the interactive game resource is T1, the loading time of the background image is T2, and the loading time of the background music is T3. During the course video playback, when the playback time reaches time T1, the interactive game resources are loaded and displayed; when the playback time reaches time T2, the background image is loaded and displayed; when the playback time reaches time T3, the background music is loaded and played.

Case 2: The video playback mode is: live broadcast mode.

In this case, the video played is a real-time recorded course video. Although the teacher will teach the course content according to the pre-prepared lesson plan during the playback process, but due to factors such as the randomness of the teacher's expression, the playback resources that need to be loaded cannot be Playing at a preset time may be in advance or wrong. Even so, it is necessary to preset a possible loading time for each playback resource to provide a time reference for downloading the playback resource. The loading time is not the time when the playback resource is actually loaded, and the loading time can be used as a download reference time for determining the starting download time of the playback resource.

In view of the above situation, in the live mode, the actual loading time of the playback resource can be controlled by the teacher. After the server obtains the playback resource loading instruction from the teacher, it forwards the playback resource loading instruction from the teacher to the client, and then the client starts the playback resource loading. Therefore, in the live broadcast mode, the triggering condition for the loading of the playback resources is: the instruction to load the playback resources is obtained.

For example, loading times T4, T5 and T6 are respectively configured for interactive game resources, background pictures and background music. Here, T4, T5 and T6 are used to determine the starting download times of interactive game resources, background pictures and background music. During the video playback process, if the teacher does not receive the playback resource loading instruction for interactive game resources, background pictures, and background music, even if the playback time reaches T4, T5, and T6, the playback resource loading will not be started. Loading starts after the teacher gives the loading instruction for the playback resource.

2. Shopping video playback scene

The video playback mode in the shopping video playback scenario is generally a live broadcast mode. It is assumed that the playback resources include: interactive game resources, product pictures, and background music.

In this case, the video played is a real-time recorded shopping video. Although the shopping guide will introduce each product according to the product introduction process prepared in advance, the shopping guide may also answer the customer's questions in the process of introducing the product. The playback resource that needs to be loaded cannot be played at the preset time, and may be played in advance or wrong. Even so, it is necessary to preset a possible loading time for each playback resource to provide a time reference for the download of the playback resource. The loading time is not the time when the playback resource is actually loaded, and the loading time can be used as a download reference time for determining the starting download time of the playback resource.

In view of the above situation, in the live mode, the shopping guide can control the actual loading time of the playback resources. After the playback server obtains the shopping guide's playback resource loading instruction, it forwards the shopping guide's playback resource loading instruction to the client, and then the client starts the playback resource loading. It can also be seen from this scene that in the live broadcast mode, the triggering condition for the loading of the playback resources is: the instruction to load the playback resources is obtained.

For example, the loading times T7, T8 and T9 are respectively configured for interactive game resources, product pictures and background music. Here, T7, T8 and T9 are used to determine the starting download time of interactive game resources, product pictures and background music. During the video playback process, if the shopping guide does not receive the playback resource loading instruction for interactive game resources, product pictures, and background music, even if the playback time reaches T7, T8, and T9, the playback resource loading will not be started, but will not start the playback resource loading. The shopping guide starts loading after the loading instruction for the playback resource.

The execution body of the embodiment of the present disclosure will be described below.

The execution subject of the embodiment of the present disclosure is the client. The client can run on electronic devices that can be connected to the Internet, such as smart phones, tablet computers, computers, and in-vehicle smart devices.

The method for downloading playback resources provided by the embodiments of the present disclosure will be described in detail below.

Referring to FIG. 1, FIG. 1 is a schematic flowchart of a method for downloading playback resources according to an embodiment of the present disclosure. The above method includes the following steps S101-S104.

Step S101: Obtain the resource amount and loading time of each playback resource.

The loading time of the playback resource indicates: during the video playback process, the actual loading time or the possible loading time of the playback resource.

During the video playback process, the client needs to download the playback resources to the local, and after the loading time arrives, the client loads the playback resources that have been downloaded to the local, so as to realize the display or playback of the playback resources.

The playback server stores data related to the played video, so during the video playback process, the client interacts with the playback server to obtain data related to the played video. Based on this, the video playback server can store the configuration information of the played video, wherein the configuration information includes: the resource amount and loading time of each playback resource that needs to be loaded during the video playback process.

In view of the above situation, in an implementation manner, the client may obtain the resource amount and loading time of all playback resources from the configuration information stored in the playback server before video playback starts.

Specifically, the client can pull the configuration information stored in the playback server, parse the configuration information, and obtain the resource amount and loading time of each playback resource.

Step S102: Predict the download duration of each playback resource according to the resource amount and network speed of each playback resource.

The network speed is: the network speed of the network used by the above client. Internet speed generally refers to the amount of data uploaded and downloaded per unit of time when connected to the Internet.

Specifically, the network speed of the above-mentioned network at the current moment may be directly determined as the network speed.

It is also possible to determine a time period that starts from the current moment and go forward by a preset time period, and use the statistical value of the network speed in the above-mentioned time period as the above-mentioned network speed. The above-mentioned statistical value may be the average value of the network speed, the maximum value of the network speed, the minimum value of the network speed, the average value of the maximum value of the network speed and the minimum value of the network speed in the above-mentioned time period, and so on.

The download duration of each playback resource may be a duration determined by a reference duration of each playback resource, wherein the reference duration is equal to the ratio between the resource amount of the playback resource and the network speed.

In one embodiment, for each playback resource, the reference duration of the playback resource may be directly determined as the download duration of the playback resource.

For example, the resource amount of the playback resource is 60MB, the network speed is 6MB/s, the reference duration of the playback resource is: 60/6=10s, and 10s is directly determined as the download duration of the playback resource.

In another embodiment, for each playback resource, the reference duration of the playback resource may be adjusted according to the first preset duration error, and the adjusted reference duration is determined as the download duration of the playback resource.

The above-mentioned first preset duration error may be set by staff according to experience, for example, the first preset duration error may be 1 s, 2 s, 5 s, or the like.

When adjusting the reference duration, the difference between the reference duration and the error of the first preset duration can be calculated as the download duration of the playback resource; the sum of the error between the reference duration and the first preset duration can also be calculated as the playback duration The download duration of the resource; a duration can also be selected from the duration range formed by the difference and the sum value as the download duration of the playback resource.

For example: the reference duration is 60s, the error of the first preset duration is 5s, and the difference between the reference duration and the error of the first preset duration is calculated as: 60s-5s=55s, and 55s can be used as the download duration of the playback resource; Calculated and obtained the sum value between the reference duration and the first preset duration error: 60s+5s=65s, 65s can be used as the download duration of the playback resource; the duration range formed from the difference and the sum value is [55s, 65s] A duration of 58s is randomly selected as the download duration of the playback resource.

Step S103: According to the download duration of each play resource, before the loading time of each play resource, determine the start download time of each play resource.

The starting download moment of the playback resource refers to the moment when the playback resource starts to be downloaded. The starting download moment of the playback resource is before the loading moment of the playback resource.

Since the time required to download the playback resource is affected by the resource amount of the playback resource and the network speed, the download duration prediction is performed according to the resource amount and the network speed of the playback resource, and the obtained download duration is highly accurate. On this basis, according to the above download duration, after determining the starting download time before the loading time of each playback resource, start downloading the playback resources from the starting download time, which can effectively ensure that the playback resources have been downloaded when the loading time arrives. Local, thereby reducing the situation that the playback resources are still being downloaded and the video playback is blocked at the loading time.

In an embodiment of the present disclosure, for each playback resource, a time before the loading time and separated from the loading time by the download duration may be determined as the starting download time.

For example: the loading time of the playback resource is 01:00:00, the download time is 20s, the time before 01:00:00 and 20s interval from 01:00:00 is: 00:59:40, and 00:59: 40 is determined as the starting download moment.

In this way, since the starting download time is before the loading time and the download duration is separated from the loading time, there is sufficient time to download the playback resources before the loading time, thereby effectively ensuring that the playback resources are downloaded to the local before the loading time, reducing the number of downloads. During the video playback process, the video playback is blocked due to waiting for the playback resources to be downloaded.

When determining the starting download time, in addition to the above method, in an embodiment of the present disclosure, for each playback resource, a target time before the loading time and the download duration interval from the loading time can also be determined. Make adjustment, and determine the adjusted target time as the starting download time.

Specifically, the target time may be adjusted in combination with the second preset duration error. For example: determine the time before the target time and the second preset time interval from the target time as the adjusted time; or determine the time after the target time and the second preset time error from the target time, as the adjusted time moment.

Step S104: During the video playing process, after reaching the starting download time of each playing resource, download each playing resource.

During the video playback process, multiple threads can be opened, wherein one thread is used to perform the video playback task, and the other threads are used to perform the playback resource download task. After the playback time reaches the starting download time of each playback resource, trigger other threads to start downloading the playback resources. In this way, through the parallel work of multiple threads, it is possible to play the video and download the playback resources at the same time, so as to realize the synchronous download during the video playback process. each playback resource.

Specifically, other threads may perform downloading tasks of multiple playback resources, or may perform downloading tasks of one playback resource.

Since each playback resource starts to be downloaded after the initial download time of the playback resource is reached during the video playback process, the trigger condition for downloading the playback resource is that the start download time of the playback resource is reached during the video playback process.

The playback resource is downloaded successfully, and after the trigger condition for loading the playback resource is satisfied, the client loads the playback resource to realize the playback of the playback resource.

In an implementation manner, when the playback resource is information that needs to be displayed, such as video, picture, text, etc., the above configuration information may further include: playback duration, playback area and other information of the playback resource. Based on this, when loading the playback resource, the client can load the playback resource into the aforementioned loading area in the user interface according to the above configuration information, and play it according to the playback duration.

It can be seen from the above that applying the solution provided by this embodiment to download playback resources is to download each playback resource during the video playback process, that is, while performing video playback, download playback resources at the same time. Before the playback starts, it waits for all the playback resources to be downloaded, and then starts the video playback, which improves the timeliness of the video playback.

In addition, in the solution provided by this embodiment, the downloading of each playback resource is specifically started after reaching the initial download time of each playback resource during the video playback process. Wherein, the above-mentioned starting download time is located before the loading time of the playback resource, and is determined according to the download duration of the playback resource. The above download duration indicates the duration required to download the playback resources at the current network speed. In this way, the playback resources are downloaded from the initial download time, which can effectively ensure that the playback resources are downloaded to the local when the loading time is reached, so that the playback resources can be downloaded at the loading time. Directly load the playback resources that have been downloaded to the local, reduce the situation of waiting for the playback resources to be downloaded during the video playback process, and further improve the timeliness of video playback.

In addition, since the video playback is performed while the playback resources are downloaded, when the user finishes watching the video playback in the middle of the video playback, the playback resource download will be stopped. The playback resources downloaded to the local are part of the playback resources of the playback video. In the prior art, all playback resources are downloaded locally in advance, which saves local storage space and network bandwidth.

The specific process of determining the starting download time of each playback resource will be described below with reference to FIG. 2a and FIG. 2b.

Suppose, the playback resources that need to be loaded during the video playback process include: playback resource 1, playback resource 2, playback resource 3 and playback resource 4. The loading times of the above playback resources are: playback resource 1:00:00:40, playback resource 1:00:00:40, playback resource 1 Resource 2: 00:01:10, Play resource 3: 00:01:50, Play resource 4: 00:02:40.

It is predicted that the download duration of each playback resource is: playback resource 1: 20s, playback resource 2: 40s, playback resource 3: 30s, playback resource 4: 50s. Each of the above download durations is represented by a bar chart, as shown in Figure 2a.

According to the above conditions, the starting download time of playback resource 1 is: 20s before the loading time 00:00:40, that is, the starting download time of playback resource 1 is 00:00:20; the starting download time of playback resource 2 is: 40s before the loading time 00:01:10, that is, the starting download time of playback resource 1 is 00:00:30; the starting download time of playback resource 3 is: 30s before the loading time 00:01:50, That is, the starting download time of playback resource 3 is 00:01:20; the starting download time of playback resource 4 is: 50s before the loading time 00:02:40, that is, the starting download time of playback resource 4 is 00:01 :50.

The initial download time and loading time of each of the above-mentioned playback resources are represented by a sequence diagram, as shown in FIG. 2b. In FIG. 2b, the positions of the dots represent the loading time of each playback resource, and the positions pointed to by the arrows represent the initial download time of each playback resource.

After the initial download time of each play resource is determined in the above step S103, the download time of each play resource may be determined according to the initial download time and loading time of each play resource. Specifically, for a playback resource, the time period from the initial download moment to the loading moment is called the loading time.

There may be overlapping time periods between the download times of each playback resource. In this case, the network bandwidth used for downloading playback resources is shared by multiple playback resources within the overlapping time period, resulting in slow download of a single playback resource. The phenomenon, in severe cases, may cause the playback resources to be incompletely downloaded when the loading time is reached. In order to alleviate the above phenomenon, after step S103, the following steps A1 to A2 may also be performed.

Step A1: Determine the target playback resources with overlapping download times according to the initial download time and loading time of each playback resource.

The download time refers to the time period from the initial download moment to the loading moment. For example, the starting download time of the playback resource is: 00:00:58, the loading time is: 00:01:00, and the download time of the playback resource is: 00:00:58-00:01:00.

The target playback resources with overlapping download times refer to playback resources with overlapping time periods between download times. Specifically, when the download times satisfy an intersecting relationship, an equality relationship, or an inclusion relationship, it means that there is an overlapping time period between the download times. A playback resource with overlapping time periods in the download time is determined as the target playback resource. Target playback assets appear in groups and do not exist individually.

Taking Table 1 as an example, Table 1 shows the download time of each playback resource.

Table 1

Play resource Ls1 00:00:20-00:00:30 Play resource Ls2 00:00:25-00:00:35 Play resource Ls3 00:00:20-00:00:50 Play resource Ls4 00:01:00-00:01:20 Play resource Ls5 00:01:00-00:01:20 Play resource Ls6 00:01:10-00:01:40

Can be obtained from above-mentioned table 1, the relation between the download time of playback resource Ls1 and the download time of playback resource Ls2 satisfies the intersection relation, and the overlapping time period between the download time of playback resource Ls1 and the download time of playback resource Ls2 is 00: 00:25-00:00:30.

The relationship between the download time of the playback resource Ls1 and the download time of the playback resource Ls3 satisfies the inclusion relationship, and the overlapping time period between the download time of the playback resource Ls1 and the download time of the playback resource Ls3 is 00:00:20-00:00 :30.

The relationship between the download time of the playback resource Ls2 and the download time of the playback resource Ls3 satisfies the inclusion relationship, and the overlapping time period between the download time of the playback resource Ls2 and the download time of the playback resource Ls3 is 00:00:25-00:00 :35;

Since the download times of playback resource Ls1, playback resource Ls2 and playback resource Ls3 all have overlapping time periods, playback resource Ls1, playback resource Ls2 and playback resource Ls3 are a group of target playback resources; similarly, playback resource Ls4, playback resource Ls4, playback resource Ls3 There are overlapping time periods between the download times of the resource Ls5 and the playback resource Ls6, and the playback resource Ls4, the playback resource Ls5 and the playback resource Ls6 are a group of target playback resources.

Specifically, when determining whether the download time overlaps, for each playback resource, among other playback resources, determine that the download time includes the first playback resource at the start of the download time of the playback resource, and determine that the download time includes the first playback resource. The second playback resource at the loading time of the playback resource, the playback resource, the first playback resource, and the second playback resource are used as the target playback resource, that is, the playback resource, the first playback resource, and the second playback resource are a group of targets Play the resource.

Taking the above Table 1 as an example, for the playback resource Ls1, the download time of the playback resource Ls3 from 00:00:20 to 00:00:50 includes the start download time of the playback resource Ls1 at 00:00:20, and the playback resource Ls3 is the first Play resource; the download time of play resource Ls2 00:00:25-00:00:35 includes the loading time of play resource Ls1 00:00:30, and the download time of play resource Ls3 00:00:20-00:00:50 Including the loading time 00:00:30 of the playback resource Ls1, the playback resource Ls2 and the playback resource Ls3 are the second playback resources, so that the playback resource Ls1, the playback resource Ls2 and the playback resource Ls3 are obtained as a group of target playback resources.

Step A2: According to the number of target playback resources and the overlapping duration of the download time, the starting download time of each target playback resource is adjusted forward.

The number of target playback resources refers to the number of playback resources with overlapping time periods.

Taking the above Table 1 as an example, there are repeated time periods between the download times of the playback resource Ls1, the playback resource Ls2 and the playback resource Ls3, and the playback resource Ls1, the playback resource Ls2 and the playback resource Ls3 are a group of target playback resources. Among the target playback resources, the number of target playback resources is 3.

There is a repeated time period between the download times of the playback resource Ls4, the playback resource Ls5 and the playback resource Ls6. The playback resource Ls4, the playback resource Ls5 and the playback resource Ls6 are a group of target playback resources. In this group, the target playback resource, the target playback resource The number of resources is 3.

Specifically, when the number of target playback resources is 2, the above-mentioned overlapping duration of download times is: the overlapping duration of download times of two target playback resources.

When the number of target playback resources is greater than 2, the overlapping duration of the above download time is: the duration determined according to the overlapping duration between the download times of each two target playback resources, such as determining the maximum duration and the minimum duration from each overlapping duration Or calculate the average duration.

In the case of overlapping download times, the initial download time of the target playback resource is adjusted forward, so that the time between the adjusted initial download time and the loading time becomes longer, that is, the time used to download the target playback resource It can effectively ensure that the target playback resource has been downloaded locally when the loading time of the target playback resource is reached.

In addition, when adjusting the starting download time of each target playback resource forward, not only the overlapping duration of the download time, but also the number of target playback resources is referenced, so that when there are more playback resources with overlapping download times, the adjusted download time The longer the time duration is, the more effectively it can be ensured that the target playback resource has been downloaded to the local when the loading time of each target resource is reached.

The aforementioned adjustment of the starting download time of each target playback resource forward refers to starting the downloading in advance, for example, starting the downloading at a time of "extended duration" in advance. For example, assuming that the starting download time is 00:01:10 and the forward "extended duration" is 10s, the time obtained by adjusting the above starting download time forward is: 00:01:00.

"Extended Duration" can be obtained by:

In an embodiment of the present disclosure for obtaining the "extended duration", the product of the number of target playback resources and the overlapping duration of the download time may be calculated to obtain the delay duration.

For example: the number of target playback resources is 3, the overlapping duration of the download time is: 10s, the calculated delay time is: 3*10s=30s, the starting download time of each target playback resource is: 00:00:30, 00:00:35, 00:00:40, adjust the starting download time of each target playback resource forward by 30s, and the adjusted start download time of each target playback resource is 00:00:00, 00:00:05, 00:00:10.

Taking Fig. 2b as an example, in Fig. 2b the download times of playback resource 1 and playback resource 2 overlap, playback resource 1 and playback resource 2 are target playback resources, and the number of target playback resources is 2, and the overlapping duration is 10s. Calculated The delay time is 2*10s=20s. The initial download time of playback resource 1 is extended forward by 20s, and the initial download time of playback resource 2 is extended forward by 20s. The adjusted start download time of playback resource 1 is 00:00:00, and the adjusted playback time The initial download time of resource 2 is: 00:00:10, and the adjusted initial download time of each playback resource is shown in Figure 2c.

In this way, the delay duration is obtained by calculating the product of the number of target playback resources and the overlapping duration of the download time, and the delay duration is relatively long; the delay duration is adjusted forward from the starting download time of each target playback resource, so that after the adjustment There is sufficient time to download the playback resources between the initial download time and the loading time, thereby effectively ensuring that the playback resources have been downloaded locally when the loading time is reached.

In another embodiment of the present disclosure for obtaining the "extended duration", after the above-mentioned delay duration is calculated in the aforementioned manner, the delay duration may be adjusted according to the third preset duration error as the final delay duration.

The above-mentioned third preset duration error can be set by the staff according to experience. For example, the third preset duration error may be: 1s, 2s, etc.

When adjusting the delay duration, the difference between the delay duration and the error of the third preset duration can be calculated as the final delay duration; the sum of the delay duration and the error of the third preset duration can also be calculated , as the final delay duration; a duration can also be selected from the duration range formed by the difference and the sum value as the final delay duration.

For example: the delay duration is 30s, the error of the third preset duration is 2s, the difference between the delay duration and the error of the third preset duration is calculated as: 30s-2s=28s, 28s can be used as the final delay duration; the sum value between the calculated delay duration and the error of the third preset duration is: 30s+2s=32s, 32s can be used as the final delay duration; the duration range formed from the above difference and the sum value [28s , 32s], a duration of 31s is randomly selected as the final delay duration.

After obtaining the adjusted starting download time in the above step A2, there may be a new overlap in the download time, that is, a new target playback resource will be generated. Therefore, step A1 can be performed again to determine the new target playback resource. After the new target playback resource is determined, step A2 needs to be performed again to adjust the starting download time of each target playback resource. This cycle is repeated until there is no target playback resource with overlapping download times, and the final adjusted start download time of each target playback resource is obtained.

In addition, after obtaining the adjusted start download time in the above step A2, in the above step S104, in the video playback process, when the adjusted start download time of each target playback resource is reached, each target playback resource is downloaded.

In order to make the initial download moment of the playback resource adapt to the real-time change of the network speed, in an embodiment of the present disclosure, the network speed can also be monitored, and the change amount of the network speed can be calculated; if the change amount is greater than the preset network speed change amount threshold , re-predict the download duration of the non-downloaded playback resources according to the resource amount of the non-downloaded playback resources and the current network speed, and adjust the starting download time of the non-downloaded playback resources according to the re-predicted download duration.

Specifically, the network speed may be monitored according to preset time intervals. The above-mentioned preset time interval may be 1s, 2s, 1min, 2min, or the like.

The variation of the network speed refers to the difference between the network speed currently monitored and the network speed used in step S102. The absolute value of the difference between the currently monitored network speed and the network speed used in step S102 can be calculated as the change amount of the network speed.

The above-mentioned preset network speed change threshold can be set by the staff according to experience.

When the above-mentioned change amount is greater than the preset network speed change amount threshold, it means that the change amount of the network speed is large, that is to say, under the current network speed, the time required to download the playback resource may be much longer or shorter than that in step S102 Predicted download time. In this case, the download duration needs to be re-predicted.

Specifically, a prediction method similar to that in step S102 may be used to re-predict the download duration of the undownloaded playback resources according to the resource amount of the undownloaded playback resources and the current network speed.

In one embodiment, for each undownloaded playback resource, the start download time can be adjusted according to the time length difference between the re-predicted download time length and the original download time length, where the current length difference is greater than 0, the start download time is moved forward Adjust the above time length difference; if the time length difference is less than 0, adjust the above time length difference backward from the start download time.

For example: the re-predicted download time is 10s, the original download time is 5s, and the time difference between the two is: 10s-5s=5s>0, the starting download time of the undownloaded playback resource is 00; 00:30 to Adjust 5s before and get 00:00:25.

The re-predicted download time is 5s, the original download time is 10s, and the time difference between the two is: 5s-10s=-5s<0, the starting download time of the undownloaded playback resource 00:00:30 is backward Adjust 5s to get 00:00:35.

In another implementation manner, for each undownloaded playback resource, the starting download time may be re-determined before the loading time according to the re-predicted download duration in the same manner as in step S103.

In this way, the change in network speed is monitored, and according to the monitoring results, the download duration of the undownloaded playback resources is re-predicted, so that the download duration is adapted to the network speed of the current network. Effectively ensure that the download of playback resources is completed before the loading time.

In an embodiment of the present disclosure, before starting video playback, pre-downloaded playback resources may be determined, and the pre-downloaded playback resources may be downloaded.

The above-mentioned pre-downloaded playback resources are playback resources whose duration between the loading time and the starting playback time does not exceed a preset duration threshold.

The start playback moment refers to the moment when the video playback starts.

The preset duration threshold can be set by the staff according to experience, for example, the preset duration threshold can be: 10s, 30s, 1min.

When determining the pre-downloaded playback resources, in one embodiment, the loading time of each playback resource for playing the video can be obtained, and the duration between the loading time and the starting playback time of each playback resource is calculated, and the duration is set to be no more than the preset duration. The playback resource of the threshold value is determined as the pre-downloaded playback resource.

For example, the loading time of each playback resource for playing the video is: 00:00:02, 00:00:04, 00:00:20:00, 00:01:00, and the loading time and starting time of each playback resource are calculated. The durations of the start playback time are: 2s, 4s, 20s, 60s, and the preset duration threshold is 5s. Since 2s, 4s<5s, 20s, 60s>5s, the playback resources and the loading time at 00:00:02 will be loaded. The playback resource whose time is 00:00:04 is determined as the pre-downloaded playback resource.

Specifically, in order to avoid waiting too long before video playback starts, the number of pre-downloaded playback resources can be limited. When determining the pre-downloaded playback resources, the duration does not exceed the preset duration threshold and the preset number of The playback resource is determined to be a pre-downloaded playback resource. The above preset number may be 3 or 5.

In an embodiment, the configuration information mentioned in the above step S101 may further record: identification information of whether each playback resource is a pre-downloaded playback resource. In view of this, the client can also determine the pre-downloaded playback resource according to the identification information recorded in the above configuration information.

In this way, when the duration between the loading time and the starting playback time does not exceed the preset duration threshold, it means that the playback resource starts to be loaded within a short time after the video playback starts. For such playback resources, it is difficult to guarantee that the download is complete when the loading time is reached. In order to prevent the blocking of video playback, it is necessary to download the pre-downloaded playback resources to the local by means of downloading in advance. During the video playback process, when the loading time of the pre-downloaded playback resources arrives, the above playback resources can be loaded directly. There will be no blocking of video playback, which improves the timeliness of playback resources.

Since there are target playback resources with overlapping download times in each playback resource, when downloading each target playback resource, multiple target playback resources may be downloaded simultaneously within the same time period. Based on the above situation, in an embodiment of the present disclosure , when downloading each target resource in the above step S104, the bandwidth amount of the network bandwidth used for downloading each target playback resource can be determined according to the order of loading time of each target playback resource, and the determined bandwidth amount is used for each target playback resource. Allocate network bandwidth, and use the allocated network bandwidth to download each target playback resource synchronously.

The earlier the loading time of the target playback resource is, the more network bandwidth is required, so as to effectively ensure that the target playback resource is downloaded when the loading time is reached. Therefore, if the loading time of one target playback resource is earlier than the loading time of other target playback resources, the network bandwidth allocated for the target playback resource is more than the network bandwidth allocated for other target playback resources.

Specifically, the weight of each target playback resource may be determined according to the sequence of the loading time of each target playback resource, and the amount of network bandwidth used for downloading each target playback resource may be determined according to the proportion of the weight of each target playback resource. .

For example: according to the order of loading time of each target playback resource, the weights of each target playback resource are 5, 4, 3, 2, and 1, respectively, and the proportion of the weight of each target playback resource is 5/15, 4/ 15, 3/15, 2/15, 1/15, the total network bandwidth that can be allocated by the client is 15M, and the network bandwidth that can be allocated to each target playback resource is: (5/15)*15M=5M, (4 /15)*15M=4M, (3/15)*15M=3M, (2/15)*15M=2M, (1/15)*15M=1M.

In the following, with reference to FIG. 3 , an overall description will be given of the application of the playback resource downloading method provided by the embodiment of the present disclosure to a course video playback scenario.

Assume that in this scenario, the video playback mode is the recording mode, and the playback resources include: interactive game resource 1, interactive game resource 2, interactive Q&A resource 1, and interactive Q&A resource 2.

The above method includes the following steps S301-S309.

Step S301: Obtain configuration information of each playback resource required for video playback.

Step S302: Traverse the configuration information to obtain the resource amount and loading time of each playback resource.

The actual loading time of each playback resource is recorded in the configuration information.

Traversing the configuration information, it is found that the resource amount of interactive game resource 1 is 10M, and the loading time is 00:01:05; the resource amount of interactive Q&A resource 1 is 20M, and the loading time is 00:01:10; the resource amount of interactive game resource 2 is is 10M, and the loading time is 00:05:00; the resource volume of interactive Q&A resource 2 is 20M, and the loading time is 00:10:00.

Step S303: Calculate the average network speed of the network.

Specifically, the average value of the sum of the highest network speed and the lowest network speed of the network in the last 5 minutes may be calculated as the above-mentioned average network speed.

For example: the maximum network speed of the network in the last 5 minutes is 3M/s, and the minimum network speed is 1M/s. The average value of the sum of the two is: (3M/s+1M/s)/2=2M/s , the average network speed is 2M/s.

Step S304: Calculate the download duration of each playback resource according to the average network speed and the resource amount of each playback resource.

Specifically, the ratio of the resource amount of each interactive resource to the average network speed is calculated, and the ratio is used as the download time of each interactive resource.

For example: for interactive game resource 1, the ratio of resource amount to average network speed is: 10/2=5s, and the download time of interactive game resource 1 is 5s;

For interactive Q&A resource 1, the ratio of resource volume to average network speed is: 20/2=10s, and the download time for interactive Q&A resource 1 is 10s;

For interactive game resource 2, the ratio of resource amount to average network speed is: 10/2=5s, and the download time of interactive game resource 2 is 5s;

For the interactive question and answer resource 2, the ratio of the resource amount to the average network speed is: 20/2=10s, and the download time of the interactive question and answer resource 2 is 10s.

Step S305: Determine the time before the loading time of each playback resource and the interval of the download duration as the start download time.

Specifically, the time before the loading time of each playback resource and at the interval of the download duration may be directly determined as the starting download time.

For example: for interactive game resource 1, the time before the loading time 00:01:05 and the interval of 5s is 00:01:00, and the starting download time of interactive game resource 1 is 00:01:00;

For interactive Q&A resource 1, the time before the loading time of 00:01:10 and the interval of 10s is 00:01:00, and the starting download time of interactive Q&A resource 1 is 00:01:00;

For interactive game resource 2, the time before the loading time 00:05:00 and the interval of 5s is 00:04:55, and the starting download time of interactive game resource 2 is 00:04:55;

For the interactive Q&A resource 2, the time before the loading time 00:10:00 and the interval of 10s is 00:09:55, and the starting download time of the interactive Q&A resource 2 is 00:09:55.

Step S306: Determine whether the download time of each playback resource has an overlapping time period. If yes, go to step S307; if no, go to step S309.

The download time of the playback resource is: the time period from the initial download time to the loading time.

For example: the download time of interactive game resource 1 is [00:01:00-00:01:05], the download time of interactive Q&A resource 1 is [00:01:00-00:01:10], and the download time of interactive game resource 2 The download time is [00:04:55-00:05:00], and the download time of interactive Q&A resource 2 is [00:09:55-00:10:00].

Among them, the download time of interactive game resource 1 [00:01:00-00:01:05] and the download time of interactive Q&A resource 1 [00:01:00-00:01:10] have overlapping time periods [00: 01:00-00:01:05].

Step S307: Calculate the product of the number of target playback resources with overlapping download times and the overlapping duration to obtain the extended duration.

The target playback resources with overlapping download times are interactive game resource 1 and interactive question-and-answer resource 1, wherein the number of target playback resources is 2, the overlapping duration is 5s, and the calculated delay duration is 10s.

Step S308 : by extending the duration, adjust the initial download time of the target playback resource forward to obtain the adjusted initial download time.

Specifically, the adjusted start download time is obtained by extending the delay time before the start download time of the target playback resource.

For example: the initial download time of interactive game resource 1 is extended 5s before 00:01:00, and 00:00:55 is obtained, that is, the adjusted initial download time of interactive game resource 1 is 00:00:55; The initial download time of Q&A resource 1 is extended 5s before 00:01:00, and 00:00:55 is obtained, that is, the adjusted initial download time of interactive Q&A resource 1 is 00:00:55.

Step S309: During the video playing process, when the starting download time of each playing resource is reached, the playing resource is downloaded.

The adjusted starting download time of interactive game resource 1 is 00:00:55, the adjusted starting download time of interactive Q&A resource 1 is 00:00:55, and the starting download time of interactive game resource 2 is 00: 04:55. The starting download time of interactive Q&A resource 2 is 00:09:55;

During the video playback, when it reaches 00:00:55, the interactive game resource 1 and the interactive Q&A resource 1 are downloaded synchronously, and the interactive game resource 1 is loaded and displayed when it reaches 00:01:05, and the interactive game resource 1 is loaded and displayed when it reaches 00:01:10 When loading and displaying interactive Q&A resource 1;

When reaching 00:04:55, download interactive game resource 2 synchronously, and load and display interactive game resource 2 when reaching 00:05:00; when reaching 00:09:55, download interactive Q&A resource 2 synchronously, and when reaching 00:05:00: Interactive Game Asset 2 is loaded and displayed at 10:00.

Corresponding to the above playback resource downloading method, an embodiment of the present disclosure further provides a playback resource downloading apparatus.

Referring to FIG. 4 , FIG. 4 is a schematic structural diagram of a playback resource downloading apparatus according to an embodiment of the present disclosure. The foregoing apparatus includes the following modules 401 - 404 .

The information obtaining module 401 is used to obtain the resource amount and loading time of each playback resource;

A duration prediction module 402, configured to predict the download duration of each playback resource according to the resource amount and network speed of each playback resource;

The time determining module 403 is used for determining the starting download time of each play resource before the loading time of each play resource according to the download duration of each play resource;

The resource downloading module 404 is used for downloading each playing resource after reaching the starting download time of each playing resource during the video playing process.

It can be seen from the above that applying the solution provided by this embodiment to download playback resources is to download each playback resource during the video playback process, that is, while performing video playback, download playback resources at the same time. Before the playback starts, it waits for all the playback resources to be downloaded, and then starts the video playback, which improves the timeliness of the video playback.

In addition, in the solution provided by this embodiment, the downloading of each playback resource is specifically started after reaching the initial download time of each playback resource during the video playback process. Wherein, the above-mentioned starting download time is located before the loading time of the playback resource, and is determined according to the download duration of the playback resource. The above download duration indicates the duration required to download the playback resources at the current network speed. In this way, the playback resources are downloaded from the initial download time, which can effectively ensure that the playback resources are downloaded to the local when the loading time is reached, so that the playback resources can be downloaded at the loading time. Directly load the playback resources that have been downloaded to the local, reduce the situation of waiting for the playback resources to be downloaded during the video playback process, and further improve the timeliness of video playback.

In an embodiment of the present disclosure, the apparatus further includes:

The first resource determination module is used to determine the target playback resources with overlapping download times according to the initial download time and loading time of each playback resource after the time determination module;

The first moment adjustment module is used for forwardly adjusting the starting download moment of each target playback resource according to the number of target playback resources and the overlapping duration of the download time.

In the case of overlapping download times, the initial download time of the target playback resource is adjusted forward, so that the time between the adjusted initial download time and the loading time becomes longer, that is, the time used to download the target playback resource It can effectively ensure that the target playback resource has been downloaded locally when the loading time of the target playback resource is reached.

In addition, when adjusting the starting download time of each target playback resource forward, not only the overlapping duration of the download time, but also the number of target playback resources is referenced, so that when there are more playback resources with overlapping download times, the adjusted download time The longer the time duration is, the more effectively it can be ensured that the target playback resource has been downloaded to the local when the loading time of each target resource is reached.

In an embodiment of the present disclosure, the first time adjustment module is specifically used to calculate the product of the number of target playback resources and the overlapping duration of the download time to obtain the delay time; before adjusting the delay time.

In this way, the delay duration is obtained by calculating the product of the number of target playback resources and the overlapping duration of the download time, and the delay duration is relatively long; the delay duration is adjusted forward from the starting download time of each target playback resource, so that after the adjustment There is sufficient time to download the playback resources between the initial download time and the loading time, thereby effectively ensuring that the playback resources have been downloaded locally when the loading time is reached.

In an embodiment of the present disclosure, the time determining module is specifically configured to, for each playback resource, determine the time before the loading time and the download time interval from the loading time as the starting download time.

In this way, since the starting download time is before the loading time and the download duration is separated from the loading time, there is sufficient time to download the playback resources before the loading time, thereby effectively ensuring that the playback resources are downloaded to the local before the loading time, reducing the number of downloads. During the video playback process, the video playback is blocked due to waiting for the playback resources to be downloaded.

In an embodiment of the present disclosure, the apparatus for downloading playback resources further includes:

a variation detection module, used to monitor the network speed and calculate the variation of the network speed;

The second moment adjustment module is configured to re-predict the download duration of the undownloaded playback resources according to the resource amount of the undownloaded playback resources and the current network speed if the variation is greater than the preset network speed variation threshold, and according to the Re-predicted download duration, adjust the starting download time of undownloaded playback resources.

In this way, the change in network speed is monitored, and according to the monitoring results, the download duration of the undownloaded playback resources is re-predicted, so that the download duration is adapted to the network speed of the current network. Effectively ensure that the download of playback resources is completed before the loading time.

In an embodiment of the present disclosure, the apparatus for downloading playback resources further includes:

The second resource determination module is used to determine the pre-downloaded playback resources before starting the video playback, wherein the pre-downloaded playback resources are: playbacks whose duration between the loading time and the starting playback time does not exceed a preset duration threshold resource;

The second resource downloading module is configured to download the pre-downloaded playback resource.

In this way, when the duration between the loading time and the starting playback time does not exceed the preset duration threshold, it means that the playback resource starts to be loaded within a short time after the video playback starts. For such playback resources, it is difficult to guarantee that the download is complete when the loading time is reached. In order to prevent the video playback from being interrupted, it is necessary to download the pre-downloaded playback resources to the local by means of advance download. During the video playback process, when the loading time of the pre-downloaded playback resources is reached, the above playback resources can be loaded directly. There will be no interruption of video playback, which improves the timeliness of playback resources.

In an embodiment of the present disclosure, the playback resource includes: an interactive resource that guides the user to participate in the playback interaction.

In this way, by loading interactive resources, it is possible to enhance the interest of video playback and increase the frequency of user parameter playback interaction.
