First embodiment
In order to solve the problem of poor user experience caused by a single type of a video cached by the existing video automatic caching method, the present embodiment provides an automatic video caching method, as shown in fig. 3, fig. 3 is a basic flow chart of the automatic video caching method provided by the present embodiment, and the automatic video caching method includes:
s301, video information and playing information of the video played on the current page are obtained.
In this embodiment, the video played on the current page is a video being watched by the current user, where the video may be played on a web page or an application program, and the video played on the current page may be a video played in a full screen of the current page; or a video played through a window on the current page, as shown in fig. 4; the type of video includes, but is not limited to, television shows, movies, documentaries, short videos, and the like. It should be noted that the video information of the video includes, but is not limited to, the total duration of the video, the score value of the video, the popularity information of the video, and the like, wherein the score value of the video is used for representing the evaluation of each user on the video, and a higher score value indicates that the video quality is better; the popularity information of the video is mainly a popularity value of the video, and the popularity value can be determined according to the browsing amount of the video and/or the browsing frequency of the video watched by the user, that is, the popularity value of the video is higher when the browsing amount and/or the browsing frequency is higher. The playing information of the video includes, but is not limited to, the playing duration when the video exits, and the opening mode of the video. The video opening mode includes but is not limited to the user searching and entering by himself, the user clicking the video recommended by the player advertisement to enter the video, and the user clicking the player to enter the video according to the recommended video preferred by the user. The self-search entering comprises the steps that when a user clicks a video to enter a video page, the user may search a certain video in a search box, a certain video is opened by clicking a connection of the certain video, the video entering is recommended according to the preference of the user, the player records the preference type of the user for watching the video when the user watches the video in a certain player, the corresponding video is recommended to the user according to the preference, the user clicks the video recommended according to the preference to open the video, the player advertises the video recommended by the player to pop up advertisements when the video enters the video, and the user clicks the advertisements to enter the video. It can be understood that, for the user to search the incoming video by himself, the user has an explicit and strong viewing intention; for a video recommended by a user clicking a player advertisement, when the video is entered, the watching intention of the user is not clear and strong; for a user to click on a recommended video of a player according to user preferences, when the user enters the video, the user may have a more definite and stronger watching desire.
And S302, judging whether the video needs to be automatically cached or not according to the video information, the playing information and a preset video automatic caching rule, if so, turning to S303, and if not, ending.
It should be understood that, according to the difference between the video information and the playing information, the preset video automatic caching rule of the present embodiment is also different, and the following cases are mainly distinguished:
the first condition is as follows: when the video information comprises the total video duration and the playing information comprises the playing duration when the video exits from the current page playing, the preset automatic video caching rule comprises the steps of judging whether the total video duration is greater than or equal to a first threshold, whether the playing duration is greater than or equal to a second threshold and whether the ratio of the playing duration to the total video duration is less than or equal to a third threshold, if so, judging that the video needs to be automatically cached, if not, judging that the video does not need to be automatically cached, namely, when the total video duration, the playing duration and the ratio of the playing duration to the total video duration all meet the thresholds, judging that the video needs to be automatically cached. The first threshold, the second threshold and the third threshold are different in size, and the specific size of each threshold can be flexibly adjusted according to the requirements of users. It can be understood that the total video duration is greater than or equal to the first threshold, the playing duration is greater than or equal to the second threshold, and the ratio of the playing duration to the total video duration is less than or equal to the third threshold, so as to avoid that the user watches half of the video which is too short to be cached, such as the video of a certain three minutes, and the user does not need to cache the video according to the preset automatic caching rule; or in order to avoid caching the long video which is about to be watched by the user, such as 130 minutes of the movie, the user exits after watching 129 minutes, and the user is judged not to be cached according to the preset automatic caching rule; or in order to avoid caching long videos with short watching time of the user, such as 130 minutes of a movie, the user exits after watching for 3 minutes, and the user is judged not to cache according to a preset automatic caching rule. This is exemplified for ease of understanding the preset automatic caching rules. For example, a movie with 120 minutes, when the user exits the movie on the page, the movie has been played for 70 minutes, the video is determined to have a total duration (120 minutes) greater than the first threshold value of 60 minutes, a playing duration greater than the second threshold value of 30 minutes, and a ratio 7/12 between the playing duration and the total duration of the video is less than 5/6, and then the movie is automatically cached. For another example, when the total duration of the documentary played on the current page is 30 minutes, and when the user exits from the video, the playing duration is 10 minutes, it is determined whether the total duration of the video is greater than or equal to the first threshold value for 20 minutes, whether the playing duration is greater than or equal to 5 minutes, and the ratio of the playing duration to the total duration of the video is less than or equal to the third threshold value 1/6, if so, the documentary is automatically cached.
Case two: when the video information comprises the total video duration and the score of the video, and the playing information comprises the playing duration when the video exits from the playing of the current page, the preset automatic video caching rule comprises the steps of judging whether the score of the video is greater than or equal to a fourth threshold or not when the total video duration is greater than or equal to a first threshold, the playing duration is greater than or equal to a second threshold, and the ratio of the playing duration to the total video duration is less than or equal to a third threshold, if so, judging that the video needs to be automatically cached, and if not, judging that the video does not need to be automatically cached; that is, the second condition is that the score value of the video is further judged on the basis of the first condition. Of course, the sizes of the first threshold, the second threshold, the third threshold and the fourth threshold are different from each other, and can be flexibly adjusted according to the type of the video. For example, for a certain video, after the total video duration, the playing duration and the ratio of the playing duration to the total video duration all satisfy the threshold values, the score value of the video is obtained to be 5.1 (assuming that the full score value is 10), and if the score value of the video is judged to be 5.1 less than the fourth threshold value to be 6.0, the video is not automatically cached; certainly, when the total video time length, the playing time length and the ratio of the playing time length to the total video time length do not accord with each threshold value, the video does not need to be automatically cached, and the score value of the video does not need to be acquired.
Certainly, in some embodiments, the preset automatic video caching rule may also be to determine whether the score value of the video is greater than or equal to a fourth threshold, and if so, when the total video duration is greater than or equal to the first threshold, the playing duration is greater than or equal to the second threshold, and the ratio of the playing duration to the total video duration is less than or equal to the third threshold, it is determined that the video needs to be automatically cached.
Case three: when the video information comprises the total video duration and the heat value of the video, and the playing information comprises the playing duration when the video played by the current page exits, the preset automatic video caching rule comprises the steps of judging whether the heat value is greater than or equal to a fifth threshold value or not when the total video duration is greater than or equal to a first threshold value, the playing duration is greater than or equal to a second threshold value, and the ratio of the playing duration to the total video duration is less than or equal to a third threshold value, if so, judging that the video needs to be automatically cached, and if not, judging that the video does not need to be automatically cached. In other words, in case three, it is further determined whether or not the heat value of the video is equal to or greater than the fifth threshold on the basis of case one. Of course, the first threshold, the second threshold, the third threshold and the fifth threshold are different in size, and can be flexibly adjusted according to the type of video or the requirement of a user. For example, the popularity value of a video is represented by the browsing amount of the video, for a certain video, after the total video duration, the playing duration and the ratio of the playing duration to the total video duration all meet each threshold, 250 ten thousand browsing amounts browsing the video are obtained, and if the browsing amount of 250 ten thousand is greater than the fifth threshold of 100 ten thousand, it is determined that the video needs to be automatically cached.
In some embodiments, the preset automatic video caching rule may further be to determine whether the heat value is greater than or equal to a fifth threshold, and if so, when the total video duration is greater than or equal to the first threshold, the playing duration is greater than or equal to the second threshold, and a ratio of the playing duration to the total video duration is less than or equal to the third threshold, it is determined that automatic video caching is required.
Case four: when the video information comprises the total video duration, the score value of the video and the heat value of the video; when the playing information comprises the playing time length when the video played by the current page exits, the preset automatic video caching rule comprises that when the total video time length is greater than or equal to a first threshold, the playing time length is greater than or equal to a second threshold, and the ratio of the playing time length to the total video time length is less than or equal to a third threshold, whether the score value of the video is greater than or equal to a fourth threshold and whether the heat value is greater than or equal to a fifth threshold are judged, if yes, the video needs to be automatically cached; that is, the fourth case is that whether the heat value and the score value of the video meet the preset conditions is further judged on the basis of the first case. The first threshold, the second threshold, the third threshold, the fourth threshold and the fifth threshold are different in size and can be flexibly adjusted according to the type of the video or the requirement of a user. For example, when the browsing frequency of the video by the user represents the heat value of the video, for a certain video, after the total time length of the video, the playing time length, and the ratio of the playing time length to the total time length of the video all satisfy the respective threshold values, the score value of the video is obtained to be 6.5 (assuming that the full score value is 10) and the browsing frequency of the video browsed by the user is 3 times per day, it is determined that the score value of the video is 6.5 and 6.5, and the browsing frequency is 3 times per day and equal to the fifth threshold value, it is determined that the video needs to be automatically cached.
It can be understood that the preset automatic video caching rule may also be to determine whether the score value of the video is greater than or equal to a fourth threshold, and determine whether the heat value is greater than or equal to a fifth threshold, for example, when the total video duration is greater than or equal to the first threshold, the playing duration is greater than or equal to a second threshold, and the ratio of the playing duration to the total video duration is less than or equal to a third threshold, it is determined that the video needs to be automatically cached.
In some embodiments, when the playing information includes a playing time length when the video exits and an opening mode of the video, in any one of the above cases, i.e., the case one, the case two, the case three, and the case four, before determining that the video needs to be automatically cached, the method further includes determining whether the opening mode of the video includes self-search entry or preference-recommended entry, and if so, determining that the video needs to be automatically cached. That is, on the basis of the above-mentioned condition one or condition two or condition three or condition four, it is further determined whether the opening mode of the video satisfies the preset condition.
And S303, controlling to automatically cache the video.
It can be understood that the automatic caching of the video is implemented under appropriate network conditions, that is, controlling the automatic caching of the video includes judging whether the current network conditions meet preset conditions, and if so, acquiring a video list to be automatically cached; and after caching the video resources to be cached in the video list, automatically caching the video. Judging whether the current network condition meets a preset condition can be judging whether the current network condition is under WIreless-Fidelity (Wi-Fi) or judging whether the current network condition is under a cellular network, if so, acquiring a video list, judging whether other caching tasks started by other users exist in the video list, if so, caching video resources to be cached in the video list, and then automatically caching the video, so that the phenomenon that the other caching tasks specific to the users are interfered by automatic caching is avoided; and if no other caching task started by the user is in the video list, directly and automatically caching the video. Certainly, after the video is automatically cached, the user may not know the existence of the video, so that after the video is successfully cached, the push message is sent to inform the user that the "xxx video is successfully cached", and after the user receives the push message, the user can timely know that the video is successfully cached.
In some embodiments, for a video player of a short video class of a "tremble" class, in a Wi-Fi environment, videos recommended to browse may be automatically cached directly according to user preferences, and after caching, when a user enters the video player again, a prompt box may pop up to prompt the user that "xxx has been cached".
In some embodiments, after controlling the automatic caching of the video, the video cache may also be updated; for example, after it is detected that a video is browsed, the cache of the video is deleted, that is, after a user browses the video, the cache is deleted; or detecting whether the video is browsed within a preset time period, if not, deleting the cache of the video or sending push information to inform, namely, if the user does not browse the video within a specified time period, deleting the cache or informing the push information below, wherein the push information can inform the user that the video is not watched, or inform the user whether the unviewed video is deleted.
It should be understood that, for the episode continuously traced by the user, the existing mode may be adopted for caching, that is, the episode continuously traced by the user is obtained, and when there is an updated episode not browsed by the user, the existing mode is automatically cached in the Wi-Fi environment.
The embodiment provides an automatic video caching method, which includes the steps of obtaining at least two kinds of information of total video duration and playing duration of a current page, a video score value, a video heat value and a video opening mode, determining whether to automatically cache video information according to matching of the total video duration and the playing duration, the video score value and the video heat value in a video opening mode, automatically caching the video information after network conditions and cached video lists meet preset conditions, and caching continuous episodes only according to video continuity compared with the existing method.
