Description

Technical Field

[0001] The present invention relates to the technical field of material management, and in particular to a material cache cleaning method, terminal and medium based on future advertisement scheduling. Background Art

[0002] The caching technology of advertising materials on the client side is a very important function for the advertising business. Especially for OTT (TV, box, micro-projector, etc.) devices, the advertising materials must be downloaded and cached in advance during the boot phase, and the advertisements are displayed in an offline playback mode. Playing locally cached ads in application opening screens, patches and other advertising positions can reduce the time users wait for materials to be loaded from the network, while effectively saving advertising traffic costs. Traditional caching strategies are usually as follows: set the allowed cache threshold, use the FIFO (first in, first out) algorithm for cache cleaning, and once the storage space of the locally cached materials exceeds the cache threshold, the advertising client will automatically delete the earliest downloaded advertising materials.

[0003] However, for OTT devices, storage space is very limited. Setting a too large cache threshold will lead to a waste of storage resources. If the cache threshold is too small, the cache needs to be cleaned frequently, resulting in frequent cache breakdown and poor cache effect. Secondly, the FIFO algorithm simply cleans up based on download time, which may cause some frequently used or important materials to be deleted prematurely, while some materials downloaded late but rarely used occupy cache space.

[0004] Therefore, the prior art still needs to be improved and enhanced. Summary of the invention

[0045] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0046] In order to solve the problems of the prior art, this embodiment provides a material cache cleaning method based on future advertising scheduling. The method based on this embodiment can manage the material cache files based on the use requirements of future advertising materials, manage the cache space more accurately, avoid the premature deletion of important or frequently used advertising materials, and ensure that low-value materials are cleaned up in time, significantly improve the utilization efficiency of the cache space, and provide better support for advertising display. In specific application, this embodiment first obtains the advertising position information, and obtains the future scheduling material list corresponding to the advertising position information. Then, the material folder corresponding to the advertising position information is obtained, and each material cache file in the material folder is matched with the future scheduling material list to obtain a matching result. Finally, based on the matching result, the material cache file that fails to match the future scheduling material list is deleted. The way of obtaining and using advertising materials in advance in this embodiment enables the advertising SDK to prepare and retain materials that may be needed in the future in advance, reduces the waiting time and traffic consumption during advertising display, and improves the user experience.

[0047] The material cache clearing method based on future advertising schedule of this embodiment can be applied to a terminal, which can be a smart product terminal such as a mobile phone, a computer, a smart TV, etc. Figure 1 As shown in , the material cache clearing method based on future advertising schedules includes the following steps:

[0048] Step S100: Obtain advertisement slot information, and obtain a future scheduled material list corresponding to the advertisement slot information.

[0049] The terminal of this embodiment first obtains the advertisement position information, which reflects the location where the future advertisement will be placed. Based on the advertisement position information, a future scheduled material list can be determined. Included in the future scheduled material list are the advertisement materials that may be scheduled in the future under the advertisement position information. This embodiment obtains the future scheduled material list corresponding to the advertisement position information in order to count and manage the advertisement materials that may be scheduled in the future, so as to manage the material cache files in the subsequent steps in combination with the usage requirements of the future advertisement materials.

[0050] Specifically, combined Figure 2 As shown, the terminal (i.e., the advertising client SDK) of this embodiment first sends an ad slot request message to the advertising server to request the ad slot information. After receiving the ad slot request message, the advertising server will respond and feedback the ad slot information to the terminal. After the terminal receives the ad slot information fed back by the advertising server, it can obtain the ad slot identifier and ad slot size of the ad slot information. The ad slot identifier is used to identify the ad slot, and the ad slot size reflects the size of the placed advertisement, i.e., the advertisement display size. The acquisition of ad slot information in this embodiment is used to determine the basic attributes and requirements of the ad slot.

[0051] Further, after obtaining the advertisement position information, this embodiment can obtain a future scheduled material list corresponding to the advertisement position information, which specifically includes the following steps:

[0052] Step S101: Obtain the advertisement slot identifier and advertisement slot size corresponding to the advertisement slot information;

[0053] Step S102: determining a target advertising material based on the advertising slot identifier and the advertising slot size;

[0054] Step S103: Generate the future scheduled material list based on the target advertising material, wherein the future scheduled material list includes the advertisement ID and the material MD5 value.

[0055] Specifically, this embodiment can obtain the ad slot identifier and ad slot size of the ad slot information. Based on the ad slot identifier and ad slot size, the advertising material that may be scheduled in the ad slot information in the future can be determined, that is, the target advertising material can be obtained. Based on the target advertising material, the future scheduled material list can be generated. The future scheduled material list of this embodiment includes information such as the advertisement ID and the material MD5 value. The material MD5 value is the unique identifier of each advertising material. This embodiment can obtain the advertising material that may be scheduled in the ad slot information in the future by obtaining the future scheduled material list corresponding to the ad slot information, thereby realizing the prediction of future advertising scheduling, so as to realize the subsequent cleaning of the material cache file.

[0056] Step S200: Obtain a material folder corresponding to the advertisement position information, and match each material cache file in the material folder with the future scheduled material list to obtain a matching result.

[0057] This embodiment further obtains a material folder corresponding to the ad slot information, and the material folder contains a plurality of material cache files, which are the advertising materials that may be placed under the ad slot information. This embodiment matches each material cache file in the material folder with the future scheduled material list to obtain a matching result, which can reflect whether the material cache file in the material folder exists in the future scheduled material list.

[0058] In one implementation, this embodiment includes the following steps when matching each material cache file with the future scheduled material list:

[0059] Step S201, traversing each material cache file in the material folder, and matching each material cache file with the future scheduled material list;

[0060] Step S202: if the material cache file is in the future scheduled material list, determining that the matching result is a successful match;

[0061] Step S203: If the material cache file is not in the future scheduled material list, it is determined that the matching result is a matching failure.

[0062] Specifically, this embodiment will loop through each material cache file in the material folder, and in the process of traversal, obtain the material MD5 value corresponding to each material cache file, and then match the material MD5 value of each material cache file with the future scheduling material list. If the material MD5 value exists in the future scheduling material list, it is determined that the material cache file corresponding to the material MD5 value exists in the future scheduling material list, and the matching result is determined to be a successful match, which means that these material cache files are materials that will be used in future scheduling. If the material MD5 value does not exist in the future scheduling material list, it is determined that the material cache file corresponding to the material MD5 value does not exist in the future scheduling material list, and the matching result is determined to be a failed match, which means that these material cache files are materials that will not be used in future scheduling.

[0063] Furthermore, in this embodiment, all the material cache files that fail to match the future scheduled material list are marked, so that in subsequent steps, these material cache files that fail to match can be quickly found and deleted to release storage space.

[0064] Step S300: based on the matching result, the material cache files that fail to match the future scheduled material list are deleted.

[0065] After matching each material cache file in the material folder with the future scheduled material list, this embodiment can obtain the material cache files that fail to match the future scheduled material list. Since these material cache files that fail to match are advertising materials that will not be used in the future schedule, these material cache files that fail to match can be deleted at this time, thereby releasing storage space and optimizing cache management. In other implementations, when this embodiment matches each material cache file with the future scheduled material list, each time a material cache file is matched, if the material cache file is not in the future scheduled material list, it can be deleted immediately, and then the next material cache file is matched. Alternatively, all material cache files can be matched, and then all matched and identified material cache files can be deleted uniformly.

[0066] In addition, based on the matching results, this embodiment can also obtain the material cache files that successfully match the future scheduled material list. These material cache files are advertising materials that may still be used in the future schedule, so the material cache files that successfully match the future scheduled material list can be retained. It can be seen that this embodiment implements a material cache cleaning method based on future advertising schedules, which can more accurately manage the cache of advertising materials and improve the utilization efficiency of cache space. The resulting improvement in advertising response rate also brings users a better advertising display experience.

[0067] In summary, the present embodiment first obtains the ad slot information, and obtains the future scheduled material list corresponding to the ad slot information. Then, obtain the material folder corresponding to the ad slot information, and match each material cache file in the material folder with the future scheduled material list to obtain a matching result. Finally, based on the matching result, delete the material cache file that fails to match the future scheduled material list. The present embodiment can manage the material cache files based on the usage requirements of future advertising materials, manage the cache space more accurately, avoid important or frequently used advertising materials from being deleted prematurely, and ensure that low-value materials are cleaned up in a timely manner, significantly improving the utilization efficiency of the cache space and providing better support for advertising display. In addition, the way in which the present embodiment obtains and utilizes advertising materials in advance enables the advertising SDK to prepare and reserve materials that may be needed in the future in advance, reducing waiting time and traffic consumption during advertising display, and improving user experience.
