Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, a user downloads a video by using a terminal, and needs to click a 'download' button on the terminal to confirm the downloading of the video. And after receiving the downloading request of the user, the terminal sends the downloading request to the server. After receiving the downloading request, the server can distribute the video requested to be downloaded to the terminal, so that the terminal can download the video. However, if the number of videos the user wants to download is large, the user must manually confirm downloading of each video to be downloaded, which is complicated.

In order to solve the above problems, the present invention provides a video downloading method, device, system, server, terminal and storage medium. The following provides a general description of the solution provided by the embodiments of the present application from a system perspective. Referring to fig. 1, fig. 1 is a block diagram of a video downloading system according to an embodiment of the present invention.

The system shown in fig. 1 comprises: server and terminal, wherein, the server includes: the system comprises a page display and play system, a Content Delivery Network (CDN) system, a user portrait system and a timing push system; the terminal can be a computer, a smart phone or other intelligent terminals used by the user.

The page display and playing system is used for receiving a download request of a user sent by the terminal, transmitting the download request to the CDN system, and sending user behavior information in the download request to the user representation system.

The CDN system can redirect the user request to the service node closest to the user in real time according to the network flow, the connection of the network node, the load condition, the distance to the user, the response time and other comprehensive information. The purpose is to enable the user to obtain the required content nearby and solve the problem of network congestion.

A user representation system for constructing a user representation. The core of building the user portrait is to generate a user feature tag of the user, wherein the user feature tag is a tag which can embody the behavior feature of the user and is obtained by analyzing the behavior information of the user. The user representation system can receive the behavior information of the user sent by the terminal and the page display and play system, and generate the user characteristic label of the user according to the obtained behavior information of the user.

The timing pushing system can determine the target user interested in the target video by utilizing the video characteristics of the target video and the user characteristic label generated by the user portrait system. And generating a video table to be downloaded of each target user, wherein the video table to be downloaded records video information of videos which need to be downloaded by the target user. And the timing pushing system pushes the video table to be downloaded to the terminal used by the target user, so that the terminal downloads the video according to the obtained video table to be downloaded.

The terminal can receive the video table to be downloaded of the target user sent by the timing pushing system, and downloads the video according to the video information recorded in the video table to be downloaded. The new play behavior information of the target user may also be sent to a user representation system in the server to enable the user representation system to update the user feature tag of the target user.

Therefore, the terminal of the system can automatically download the video according to the video table to be downloaded sent by the server, so that the process that a user confirms the downloading is omitted, and the user experience is improved.

The present invention will be described in detail with reference to specific examples. Fig. 2 is a schematic flowchart of a first flowchart of a video downloading method applied to a server according to an embodiment of the present invention, where the method includes:

s201: and acquiring video characteristics of the target video.

The target video can be a video updated in the server, or a popular video obtained by the server according to the order of the video on demand times from high to low.

In one implementation, the obtained video features may be preset video feature tags (e.g., horror, love, action, home, animation, etc.) that can represent features of the target video. A target video may have one or more video feature tags.

In the present application, the features of the video are represented by the video feature tags of the video, and the method of actually obtaining the user features is not limited to this.

S202: and determining a target user interested in the target video according to the acquired video characteristics and the user characteristics of the user.

The user characteristics may be characteristics of the user obtained according to the registration information of the user, or characteristics of the user obtained according to the playing behavior information of the user.

In one implementation, the server may obtain a user feature tag generated by the user representation system, and determine the target user according to the number of matching video feature tags of the target video with the user feature tags. How to determine the target user according to the number of the video feature tags of the target video matched with the user feature tags will be described in detail in the following embodiments.

The number of the determined target users may be one or more, and the application is not limited thereto.

S203: and generating a video table to be downloaded, which is used for downloading the target video by the determined target user.

In one implementation, the target user may be more than one user. For each target user, the server may determine, as a video that is of interest to the target user, a target video whose number of matches between the video feature tag and the user feature tag of the target user is greater than a preset first threshold, that is, a video to be downloaded of the target user. And recording the determined video information of the video to be downloaded of the target user in a video table to be downloaded of the target user, wherein the video information of the video to be downloaded can comprise the video name, the video type, the video definition and the like of the video to be downloaded.

For example, the table of videos to be downloaded of a target user may contain information such as "the twelfth set of western notes, animation, high definition", "the fifth set of sanguo rehearsal, drama, bianshi", "shaolin temple, movie, high definition", etc.

S204: and sending the video table to be downloaded to the determined terminal used by the target user, so that the terminal downloads the target video according to the video table to be downloaded.

In one implementation mode, the server can send the new video table to be downloaded of each target user to the terminal used by the target user at the moment that the server access amount is small after the new video table to be downloaded is generated each time, so that the terminal can avoid the access peak period of the server to access the server, and downloads the video according to the video information of the video to be downloaded recorded in the new video table to be downloaded, thereby avoiding increasing the burden of the server and smoothly finishing the downloading of the target video.

Of course, the video list to be downloaded generated in one day may also be sent to the terminal used by the target user within a fixed time period of the day, for example, 1 to 2 points in the morning of each day.

The present application is described only by way of example, and is not limited to the manner in which the video table to be downloaded is transmitted to the terminal used by the target user.

As can be seen from the above, in the scheme provided by this embodiment, the server may determine the target user according to the video characteristics of the target video and the user characteristics of the user, generate the video table to be downloaded of the target user, and send the video table to be downloaded to the terminal used by the target user, so that the terminal directly downloads the target video according to the video table to be downloaded, thereby saving the confirmation process of the user and improving the user experience.

In an embodiment of the present invention, referring to fig. 3, fig. 3 is a flowchart illustrating a process of determining a target user according to an embodiment of the present invention, and is applied to a server, where a target user interested in a target video is determined according to an obtained video feature and a user feature of a user (S202), including:

s2021: and calculating the number of the characteristics matched with the user characteristics of the user in the acquired video characteristics for each user.

S2022: and determining the users with the calculated number of the features larger than a preset first threshold value as target users interested in the target video.

In an implementation manner, for each user, the server may calculate the number of video feature tags of a target video that is the same as the number of user feature tags of the user, and if the number of the user feature tags of the user that is the same as the number of the video feature tags of the target video is greater than a preset first threshold, it may be determined that the user is a target user interested in the target video, and the target video is determined to be a video to be downloaded of the user.

For example, the first threshold may be 4, the target video is the latest movie "distortion gold 3", and the preset video feature labels include: transformers, europe and america, movies, wars, mechanics, action, adventure. A user feature tag for a user comprising: europe and america, movies, television dramas, adventure, classics, love, war, and action. The same labels are: the same number of labels is larger than a first threshold value, so that the user can be determined to be a target user of the movie & lttransformers 3 & gt, and the movie & lttransformers 3 & gt is a video to be downloaded of the target user.

As can be seen from the above, in the scheme provided in this embodiment, the server may determine the target user according to the number of features that are matched between the video feature of the target video and the user feature of the user. The video interested by each target user can be determined, so that personalized automatic downloading of the video can be realized, and the user experience is improved.

In an embodiment of the present invention, applied to a server, a table of videos to be downloaded for downloading a target video by a determined target user is generated (S203), including:

s2031: and determining the moment to be downloaded of each target user for downloading the target video.

S2032: and generating a video table to be downloaded, which is used by each target user for downloading the target video, according to the determined moment to be downloaded, at which each target user downloads the target video.

In one implementation, the server may reasonably allocate the downloading time for downloading the target video to each target user according to the geographic location of the target user, the size of the target video, the number of the target users, and other factors.

For example, when the CDN system access pressure is usually the minimum from 12 am to 6 am, the target user's downloading time for downloading the target video may be evenly distributed in this period. The generated video list to be downloaded comprises the time to be downloaded corresponding to the target video, so that the terminal can download the corresponding target video according to the time to be downloaded recorded in the video list to be downloaded.

As can be seen from the above, in the scheme provided in this embodiment, the server may determine the time to be downloaded when each target user downloads the target video, and further generate the video table to be downloaded. The video table to be downloaded can enable the terminal to download the target video according to the moment to be downloaded determined by the server, and guarantee the automatic downloading of the video to be completed smoothly.

In an embodiment of the present invention, the determining, by the server, a time to be downloaded at which each target user downloads the target video includes:

the determined geographic location of the target user;

a size of the target video;

the determined number of target users.

In one implementation, the server may calculate the download time based on at least one of the determined geographic location of the target user, the size of the target video, and the determined number of target users.

For example, target users in beijing, shanghai, guangzhou, etc. usually work late, the downloading time of the target users in these areas for downloading the target video can be scheduled to be a little bit later than zero morning, and the downloading time of the target users in other areas for downloading the target video can be scheduled to be a little bit later than ten hours later than night, so as to ensure that the rest time of the target users can be fully utilized and the server can be prevented from being overloaded at the same time; for a target video occupying a small storage space, downloading the target video can be preferentially arranged, so that the terminal can complete downloading of the target video as far as possible, and the situation that the terminal does not have a viewable video is avoided; for a target video, if more target users need to download the target video, the target users can be divided into different groups, and the downloading time of the target users in different groups for downloading the target video is different, so that the problem that the server is overloaded at the same time is avoided.

Of course, when the downloading time is actually determined, factors in various aspects need to be comprehensively measured, so that the terminal can finish downloading all target videos in the scheduled time, and the server is prevented from being overloaded at the same time.

In an embodiment of the present invention, referring to fig. 4, fig. 4 is a second flowchart illustrating a video downloading method applied to a server according to an embodiment of the present invention, where the method further includes:

s205: and determining the first preset number of videos as hot videos according to the sequence of the playing times from high to low in the preset first time period.

S206: and determining the time to be downloaded of each hot video downloaded by each determined target user.

In the embodiment of the present application, the execution order of S205 and S206 is not limited, and the execution may be performed before S2032A.

Generating a video table to be downloaded, which is used by each determined target user for downloading the target video, according to the determined moment to be downloaded, at which each target user downloads the target video (S2032), wherein the method comprises the following steps:

S2032A: and generating a video table to be downloaded, which is used by the target user to download the target video and the hot video, according to the determined time to be downloaded when each target user downloads the target video and the determined time to be downloaded when each target user downloads each hot video.

In one implementation manner, according to the sequence of the playing times from high to low in the preset first time period, the previously preset first number of videos are determined to be used as the popular videos. And taking the hot video as the video to be downloaded of all target users, and calculating to obtain the time to be downloaded of the hot video. The method for calculating the time to be downloaded of the popular video may refer to the method for determining the downloading time of the target video, and is not described herein again.

Therefore, in the scheme provided by this embodiment, the server can use the hot video as the video to be downloaded of the target user to push the video to the terminal used by the target user, so that the terminal completes automatic downloading of the hot video, the target user is ensured not to miss watching of the hot video, and user experience is improved.

In an embodiment of the present invention, applied to a server, the method further includes:

The type of video that the user is interested in is not constant and, therefore, the user characteristics of the user may change over time. In one implementation manner, the server may receive new play behavior information of the target user sent by a terminal used by the target user, and recalculate to obtain the user feature tag of the target user in combination with the historical play behavior information of the target user.

As can be seen from the above, in the scheme provided in this embodiment, for each target user, the server may update the user characteristics of the target user by using the received new playing behavior information of the target user, so as to ensure that the latest user characteristics of the user are grasped in real time, provide a video meeting the user interest for the user, and improve the user experience.

Fig. 5 is a schematic flowchart of a first flowchart of a video downloading method applied to a terminal according to an embodiment of the present invention, where the method includes:

s501: and receiving a video table to be downloaded, which is sent by the server and used for downloading the target video.

The target video is a video that is of interest to the target user, specifically, the target video may be one video or more than one video, and the present application does not limit this. The target user is a user using the terminal, the target user is determined by the server according to the video characteristics of the target video and the user characteristics of the user, and the user characteristics of one user are determined according to the playing behavior of the user. The video table to be downloaded may record video information of the target video, and the video information may include information such as a video name, a video type, and video definition of the target video.

S502: and downloading the target video according to the video table to be downloaded.

In this embodiment, after receiving the video table to be downloaded sent by the server, the terminal may download the target videos according to the sequence of the target videos recorded in the video table to be downloaded; the target video can also be downloaded according to the downloading sequence set by the terminal; and downloading the corresponding target video at the specified time according to the time rule set by the terminal.

When downloading the target video, the terminal sends a request to the server according to the video information of the video to be downloaded recorded in the video table to be downloaded, and the steps are consistent with the steps of sending the request to the server by the terminal in the existing video downloading process and the steps thereafter, and are not repeated herein.

Therefore, in the scheme provided by the embodiment, the terminal can download the target video according to the received video list to be downloaded, so that the confirmation process of the user is omitted, and the user experience is improved.

S602: and judging whether the available storage space of the terminal is smaller than a preset second threshold, if so, executing S603, and if so, executing S604.

S603: the storage space is released and S604 is performed.

The terminal used by the user has a fixed storage space, and each target video downloaded to the terminal occupies a certain storage space. When the available storage space of the terminal is smaller than a second threshold value, the terminal releases the storage space until the available storage space of the terminal meets the size of the space for downloading the target video, and then the target video can be downloaded; when the available storage space of the terminal is greater than or equal to the second threshold, the target video can be directly downloaded.

The available storage space of the terminal satisfies the size of the space for downloading the target video, and may be that the available storage space of the terminal is greater than or equal to the second threshold, or that the available storage space of the terminal is greater than or equal to the size of the target video to be downloaded by the terminal. The invention is not limited thereto.

When the terminal releases the storage space, the downloaded video which is not watched by the user for a long time in the terminal can be preferentially deleted, and the downloaded video which is watched by the user and ended can be preferentially deleted. The method for releasing the storage space by the terminal is not limited in the present invention.
