Detailed Description
In order to better and clearly show the technical scheme of the invention, the invention is further described below with reference to the accompanying drawings.
It is understood by those skilled in the art that the invention discloses a control method for cleaning short video cache, which determines how to clean short video through interaction with a background server, so as to improve the efficiency and accuracy of cleaning storage space.
Specifically, in one specific embodiment, the control method may be implemented by the following steps:
And a step a, receiving a short video cache directory from a short video server. Preferably, a short video server sends a buffer directory of a short video stored by a short video application program corresponding to the short video server to a control device (not shown in fig. 1 and fig. 2) provided by the present invention, so that the control device obtains the corresponding short video buffer directory.
And then, executing the step b, and cleaning the short video cache in the user equipment according to the short video cache directory. In the case that an accurate short video cache directory has been determined, it is preferable to delete all the short videos in the short video cache directory directly, so as to release the storage space.
Further, it will be understood by those skilled in the art that, in other embodiments, the short video cache directory may come from a third-party background server, for example, a background server specifically organizes short video cache directories corresponding to various short video applications, so that a plurality of short video cache directories may be given at a time, which does not affect the essential content of the present invention, and is not described herein.
Further, it will be understood by those skilled in the art that in the step a, the corresponding short video cache directories may be obtained from the plurality of short video servers, so that the plurality of short video cache directories, for example, the jittered short video, the fast-handed short video, etc., are also finally determined, which will not be described herein.
Still further, as will be appreciated by those skilled in the art, in another embodiment, the method further comprises the following steps prior to step a: and sending request information to the short video server for acquiring the short video cache directory. That is, the control device first sends request information to one or more short video zone servers, where the request information originally requests to obtain the corresponding short video cache directory. Correspondingly, after receiving the requests, the short video server sends corresponding short video cache catalogs to the control device.
Further, it will be appreciated by those skilled in the art that in order to increase security, the request information issued by the control means should include handshaking signals so that the short video server determines that this is not a malicious request information. Such modifications are within the scope of the present invention and are not described herein.
Further, fig. 1 shows a specific flow chart of a control method for short video cache cleaning according to a first embodiment of the present invention, specifically, the method includes the following steps:
First, the flow advances to step S101 to receive a short video cache directory from a short video server. Specifically, the method can be implemented by referring to the step a, and will not be described herein.
Step S102 is then performed to determine a short video retention list. Not every short video will be deleted for different implementation needs. For example, in this embodiment, a portion of the short video is reserved, and it is preferable to reserve a specific short video according to the short video reservation list. Therefore, in this step, a short video reservation list is determined. The short video retention list may be validated in a number of ways, for example a dialog box may be popped up, the user may be asked to select the short video desired to be left, etc. A description of this implementation follows.
Finally, step S103 is performed to delete the short video in the short video cache directory outside the short video reservation list. And according to the short video reserved list, deleting all short videos outside the list. Preferably, the deletion is a unrecoverable delete operation.
Further, it will be appreciated by those skilled in the art that in a preferred embodiment, the control means issues a hot short video list request message to the short video server and accordingly receives a hot short video list from the short video server and uses the hot short video list as the short video hold list. In this way, a short video reservation list to be reserved can be easily obtained.
Fig. 2 shows a specific flow chart of a control method for short video cache cleaning according to a second embodiment of the present invention based on the embodiment shown in fig. 1.
Specifically, for the above step S102, the step of determining how to determine the short video reservation list may be implemented by the following steps:

Those skilled in the art understand that communication between a plurality of user terminals can be realized by means of p2p and other technical means, so as to realize sharing of short video program information in short video application programs in the plurality of user terminals respectively. Such a p2p technical manner may be implemented by the control device provided by the present invention, and will not be described herein.
Then, step S202 is performed to count the short video program information, that is, to count the short video program information in the plurality of user equipments.
Finally, step S203 is executed, and the short video information with the top three ranking numbers is used as the short video reservation list. By a simple ranking approach, the short video retention list most worth being retained is determined.
In another preferred embodiment, the step S203 may be further refined as the following steps:
Step b13 "is executed first, and weighting processing is performed on the ranking information of the short video and the playing duration of the short video. Besides ranking the short videos, weighting is carried out by adopting at least two of the short videos according to the playing time length of the short videos.
And then, step b 14' is carried out, ranking is carried out according to the weighted processing result, and short video information with the top three ranking numbers is used as the short video reserved list. In this way, short video with longer or shorter play time is more easily retained.
Referring to the embodiment shown in fig. 1 and 2, it is understood by those skilled in the art that, preferably, before performing step b or step S103, the following steps are further performed:
And judging whether the available storage space of the user equipment is lower than a first threshold value, and if the available storage space is lower than the first threshold value, executing the operation of deleting the short video, namely executing the step b or the step S103. By such a step, it is possible to realize an operation of cleaning the played short video only when the storage space is relatively lacking.
Still further, referring to the embodiment and the variation shown in fig. 1 and fig. 2, those skilled in the art understand that the present invention further provides a control device for short video cache cleaning, which preferably includes the following devices:
