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.

Example (b):

CDN: it is called Content Delivery Network, i.e. Content distribution Network. The CDN is an intelligent virtual network constructed on the basis of the existing network, and by means of edge servers deployed in various places and functional modules of load balancing, content distribution, scheduling and the like of a central platform, a user can obtain required content nearby, network congestion is reduced, and the access response speed and hit rate of the user are improved. The key technology of the CDN is mainly content storage and distribution technology.

When a traditional user watches a video, the user needs to access the CDN to request video data, which brings traffic to the CDN, and the traffic accumulation is bandwidth. The increase of the bandwidth of the CDN affects the speed at which the terminal downloads the video data from the CDN, which further causes the video playing of the terminal to be paused, thereby affecting the user experience. Especially, when a video start-up process is paused, the video start-up speed is slow, which causes poor experience of the user on the application program providing video play in the terminal and reduces the stickiness of the user on the application program.

In order to save the bandwidth cost of the CDN, the P2P technology is developed. P2P technique: also called peer-to-peer internet technology, is a new network technology, and relies on the computing power and bandwidth of participants in the network, rather than aggregating the dependence on a few servers. P2P networks are commonly used to connect nodes through Ad Hoc connections. Such networks can be used for a variety of purposes, and various archive sharing software has been widely used. P2P technology is also used in data communication for real-time media services like VoIP.

Generic P2P download scheme: when other users need to watch the video download data, the video data is downloaded from the existing terminal caching the video through the P2P technology. The general P2P downloading scheme is mainly used to save bandwidth cost of the CDN, but the user terminal is unstable, and there are also problems of network outage, network fluctuation, deletion of video data, and the like at any time, and poor user experience.

Further, in the patent application with publication No. CN108200478A, the video that the user has watched can be pushed to the router, and when other users play, the video data can be downloaded from the router to other users, and the data can be transmitted by using the P2P technology to achieve the purpose of data sharing. The scheme downloaded from the router based on the P2P technology is also only for increasing a scheme form of a terminal device, and needs video data watched by a user to be cached on the router to provide data sharing for other users, and has no difference from the general P2P downloading scheme, and both of them have the problem of bad user experience.

In view of this, embodiments of the present application provide a video playing method, apparatus, device, and storage medium, which can not only reduce CDN bandwidth, but also improve video playing speed, reduce the occurrence of a jam during video playing, and improve user experience.

First, in consideration of the general regularity of video watching, the inventor of the present application may regard a period of a day in which a large number of users request to play video as a video playing peak period, and regard a period of a day in which a small number of users request to play video as a non-video playing peak period.

For example, the time of day may be divided into a video playing peak period and a non-video playing peak period, such as afternoon, evening are generally concentrated time periods when the user watches the video, and early morning is generally a time period when the user watches the video least, so the video playing peak period may be determined as 11 o 'clock-24 o' clock of the day, and the non-video playing peak period may be determined as 0 o 'clock-11 o' clock of the day.

The method and the device can actively push the video data which can be watched by the user from the CDN to the router to which the current user belongs (the router to which the current user belongs can be regarded as the router nearest to the user) in advance during non-video playing peak periods, the user does not need to download the video data from the CDN when watching the video, the video data is directly downloaded from the nearest router, the router nearest to the user has higher stability, and the router nearest to the user caches the video data which can be watched by the user, therefore, when the user requests to watch the video, the video data cached in the router closest to the user has a high hit for the video requested to watch by the user, and because the router closest to the user has high stability relative to the user, therefore, the video playing starting process can be accelerated, and the occurrence of the pause condition in the video playing process can be reduced.

Particularly, when the router closest to the user caches video playing start data which can be watched by the user, the storage space of the router can be saved so that the router can store more video data which can be watched by the user, the purpose of accelerating the video playing start speed can be achieved, and further, the downloading speed of the video playing start data is improved, so that the buffer time is provided for downloading the residual video data except the video playing start data in the video, and the occurrence of a pause condition in the video playing process is reduced.

Fig. 1 is a schematic diagram of a video data downloading system according to an embodiment of the present application.

As shown in fig. 1, there are three current ways for a terminal to download video data, where the first way may be to download video data from a CDN, the second way may be to download video data from a router based on P2P technology, and the third way may be to download video data from other terminals based on P2P technology.

When a user requests to watch a video by sending a video playing request by using an application program on a terminal device (including a PC, an Android device, an iOS device, etc.), video data is downloaded to the terminal device of the user by accessing a CDN or a P2P technology, all video playing requests need to be forwarded by a router, and all video playing requests forwarded by the router can be collected correspondingly. For example, if video data is downloaded from the CDN, DNS resolution (forwarding through a router) is required first, a real IP address of the CDN is taken, and then the video data is requested from the CDN; if video data is downloaded by using the P2P technology, a connection needs to be established to other terminals/routers through the router before data transmission can be performed by using the P2P technology.

In the embodiment of the application, the router can analyze the video playing request sent by the user in real time to determine the video data which are possibly watched by the user and are required to be cached in the router, and download the video data which are possibly watched by the user from the CDN in the non-video playing peak period, so that when the video playing request sent by the user is received, the video data requested to be played by the video playing request can be directly downloaded from the router.

It should be noted that the router may receive video playing requests sent by many users, but when analyzing the video playing requests received by the router, the router may analyze only the user to which the video playing request that uses the router as the first-hop router belongs, so that video data that the user may watch may be cached in the router closest to the user, because the router closest to the user has more stability in the process of downloading the video data by the user, and thus, the video data downloading speed may be effectively increased.

It should be noted that, after a user sends a video playing request through a terminal, a first router in the internet for receiving the video playing request may be considered as a first-hop router of the video playing request, the user may be considered as a user who uses the router as a first-hop router, and the first-hop router may be considered as a router closest to the user.

Fig. 2 is a flowchart of a method for locally caching video data in a router according to an embodiment of the present disclosure.

As shown in fig. 2, the method includes:

s201, determining at least one historical video playing request received by a router;

the method for caching video data locally at a router, as shown in fig. 2, provided by the embodiment of the present application may be performed separately for each router in the internet.

In the embodiment of the present application, the video playing request received by the router may be analyzed, and when the video playing request received by the router is analyzed, the video playing request received by the router may be referred to as a historical video playing request. Specifically, at least one historical video playing request received by the router may be analyzed, and the router may be determined to be a historical user of the first-hop router by analyzing the at least one historical video playing request received by the router, so as to predict a target video to be played by the historical user, and download video data of the target video to be played by the historical user from the CDN to the router during a non-video playing peak period.

As a preferred embodiment of the present application, the at least one historical video play request received by the router may be all historical video play requests received by the router.

As another preferred implementation manner of the embodiment of the present application, the at least one historical video playing request received by the router may be all historical video playing requests received by the router within the recent historical time period.

In this embodiment of the application, the specific content of the at least one history video playing request received by the router may be set by the inventor according to the needs of the inventor, which is not limited herein.

S202, screening all first video playing requests which take the router as a first-hop router from at least one historical video playing request;

in the embodiment of the application, after determining at least one historical video playing request received by a router, all historical video playing requests that use the router as a first-hop router may be screened from the at least one historical video playing request received by the router, and for convenience of distinguishing, each screened historical video playing request that uses the router as a first-hop router may be temporarily referred to as a first video playing request.

S203, predicting a target video to be played by the historical user according to all first video playing requests sent by the same historical user;

in the embodiment of the application, after at least one historical video playing request received by a router is determined, and all first video playing requests taking the router as a first hop router are determined from the at least one historical video playing request received by the router, all the screened first video playing requests can be grouped according to different sending historical users, all the first video playing requests sent by the same historical user are divided into one group, videos to be played by the historical users sending the group of first video playing requests are predicted according to each group of first video playing requests, and the videos to be played by the historical users can be changed into target videos for convenience of distinguishing.

In the embodiment of the present application, after all the first video play requests of the router are screened from at least one historical video play request received by the router (all the first video play requests of the router are all the historical video play requests of the router that are taken as a first-hop router in the at least one historical video play request received by the router), all the first video play requests sent by the same historical user in all the first video play requests of the router may be considered as one group, so that all the first video play requests of the router are divided into multiple groups, the sending historical users of each group of first video play requests of the router are different, and the following operations are performed for each group of first video play requests of the router: and predicting a target video to be played by the historical user sending the group of first video playing requests by using the group of first video playing requests, wherein the historical user sending the group of first video playing requests can be regarded as a historical user taking the router as a first-hop router.

For a specific way of predicting the target video to be played by the historical user according to all the first video playing requests sent by the same historical user, please refer to the description of fig. 3 below, which is not repeated herein.

S204, requesting the CDN for the video data to be played by the historical user in the non-playing peak period based on the target video to be played by the historical user.

In the embodiment of the application, after determining that the router is used as each historical user of a first-hop router according to at least one historical video playing request received by the router and predicting the target video to be played by each historical user, video data of the predicted target video to be played by each historical user can be respectively requested to the CDN during a non-video playing peak period.

The request for the video data to be played by the historical user from the CDN during the off-peak period based on the target video to be played by the historical user may be the request for the video data of the target video to be played by the historical user from the CDN during the off-peak period based on the target video to be played by the historical user.

Further, after the router requests video data to be played by the historical user from the CDN, the video data to be played by the historical user requested by the CDN may be stored locally in the router, and the video data to be played by the historical user locally stored in the router may be considered as the video data of the historical user locally stored in the router.

For example, if the video data 1 to be played by the historical user a is requested from the CDN and then the video data 1 is stored locally in the router 1, and the video data 2 to be played by the historical user b is requested from the CDN and then the video data 2 is stored locally in the router 1, the video data 1 locally stored in the router 1 is the video data of the historical user a, and the video data 2 locally stored in the router 1 is the video data of the historical user b.

As a preferred implementation manner of the embodiment of the present application, the video data to be played by the historical user requested by the CDN may be cached locally in the router.

For a specific implementation manner of requesting historical video data to be played by a user from the CDN during an off-peak period based on a target video to be played by the user, please refer to the detailed description in fig. 4, which is not repeated herein.

According to the embodiment of the application, the predicted video data to be played by the historical user can be cached in the router closest to the historical user, so that the historical user can conveniently acquire the video data from the router closest to the historical user when requesting to play the video subsequently, the video playing speed is improved, and the occurrence of the video blocking condition in the video playing process is reduced.

Fig. 3 shows a method for predicting a target video to be played by a historical user according to all first video playing requests sent by the same historical user according to an embodiment of the present application.

As shown in fig. 3, the method includes:

s301, counting at least one second video playing request requesting playing of the same video in all first video playing requests sent by the same historical user;

in the embodiment of the application, at least one historical video playing request received by a router is determined, after all first video playing requests taking the router as a first-hop router are screened out from the at least one historical video playing request received by the router, all screened out first video playing requests are divided according to different sending historical users, all first video playing requests sent by the same historical user are divided into one group, and then the following processes are respectively executed for each group of first video playing requests: dividing all the first video playing requests in the group of first video playing requests according to different video playing requests, and dividing all the first video playing requests in the group of first video playing requests for playing the same video into one group, so that the group of first video playing requests are further divided into one or more groups, the videos requested to be played by the first video playing requests in different groups are different, and the videos requested to be played by the first video playing requests in the same group are the same. For the sake of convenience of differentiation, each first video playback request in the group may be referred to as a second video playback request for each group. Thus, a small set of first video playback requests can be considered a set of second video playback requests, a set of second video playback requests including at least one second video playback request requesting playback of the same video.

S302, determining the total request times and the total playing time of the historical users for the video according to at least one second video playing request sent by the same historical user and requesting to play the same video;

in the embodiment of the present application, the following processes are respectively performed for each group of second video playing requests determined in step S301: and determining the total request times and the total playing time of the historical users sending the group of second video playing requests for the videos requested to be played by the group of second video playing requests. The number of the second video playing requests in the group of second video playing requests can be determined as the total number of times of requests of the historical user sending the group of second video playing requests for the video requested to be played by the group of second video playing requests; and determining the sum of the video playing time lengths of all the second video playing requests in the group of second video playing requests as the total playing time length of the video requested to be played by the group of second video playing requests of the historical user sending the group of second video playing requests.

The time length of the video requested to be played by the video playing request, which is watched by the historical user based on the video playing request after the video playing request is sent by the terminal, can be regarded as the video playing time length of the video playing request.

And S303, predicting the target video to be played by the historical user according to the total request times and the total playing time of the historical user to the video.

In this embodiment of the application, after determining, for each group of second video play requests determined in step S301, the total request times and the total play time of the videos requested to be played by the group of second video play requests by the historical users sending the group of second video play requests, videos to be played by the historical users sending the group of second video play requests may be predicted according to the total request times and the total play time of the videos requested to be played by the group of second video play requests by the historical users sending the group of second video play requests, and in order to facilitate distinguishing, videos to be played by the historical users sending the group of second video play requests may be called target videos.

Taking a group of second video playing requests as an example, after determining the total request times and the total playing time length of the videos requested to be played by the group of second video playing requests by the historical users sending the group of second video playing requests, the playing information of the videos requested to be played by the group of second video playing requests by the historical users sending the group of second video playing requests can be calculated according to the total request times and the total playing time length (the playing information represents the possibility that the videos requested to be played by the group of second video playing requests are requested to be played by the historical users sending the group of second video playing requests); and judging whether the playing information meets preset playing conditions or not, and if the playing information meets the playing conditions, predicting and sending the target video to be played by the historical user of the group of second video playing requests according to the video requested to be played by the group of second video playing requests.

For example, taking a group of second video playing requests as an example, if the video requested to be played by the group of second video playing requests is video 1, the historical user sending the group of second video playing requests is user 1; the total request times of the user 1 to the video 1 determined according to the group of second video playing requests is N, and the total playing time length of the user 1 to the video 1 determined according to the group of second video playing requests is T; and calculating the product of the total request times N and the total playing time T as the playing information of the user 1 to the video 1, if N x T meets the preset playing condition, hitting the video data to push the scene in advance, and predicting the target video to be played by the user 1 according to the video 1.

In the embodiment of the present application, the playing condition may be a preset value, and if the playing information exceeds the preset value, it is determined that the playing information satisfies the playing condition, and if the playing information does not exceed the preset value, it is determined that the playing information does not satisfy the playing condition.

Still taking the above as an example, if the playing condition is the preset value P, if N × T > P, it is determined that the playing information satisfies the playing condition; and if N x T is not larger than P, determining that the playing information does not meet the playing condition.

In this embodiment of the present application, taking a group of second video playing requests as an example, a manner of predicting a target video to be played by a historical user who sends the group of second video playing requests according to a video requested to be played by the group of second video playing requests may be as follows: and acquiring the video type of the video requested to be played by the group of second video playing requests, and predicting the target video to be played by the historical user sending the group of second video playing requests according to the video type of the video. If the video type of the video is a television episode type, determining a next episode adjacent to the episode to which the video belongs as a target video to be played by the historical user; and if the video type of the video is a movie type or a short video type, determining the video related to the video as a target video to be played by the historical user.

The video type of the video is the same as the video type of the target video to be played by the historical user predicted according to the video type of the video.

As a preferred implementation manner of the embodiment of the present application, if the video type of the video is a movie type, a recommended movie related to the video may be used as the video related to the video; if the video type of the video is a short video type, other short videos related to the video can be used as the video related to the video.
