[0068] Example 1

[0069] like Figure 1 As shown, this embodiment provides a screen saver dynamic update method, wherein the screen saver refers to a program or graphic that appears to protect the display or screen after the electronic product such as a computer or mobile phone is not used for a long time. The screen saver usually displays beautiful patterns, animations or scrolling text and other contents on the screen to avoid screen burn-in or imprinting caused by long-term stay on the screen. The screen saver dynamic update method in this embodiment 1 includes the following steps:

[0070] S1: Acquire information data of the screen saver to be updated from the background, wherein the information data includes download address data of the screen saver and location data of the screen saver;

[0071] In order to enrich the content of the screen saver, this embodiment adopts the method of downloading a new screen saver from the background and saving it locally to update the screen saver. The display device displays the screen saver saved locally. This embodiment first obtains information data of the screen saver to be downloaded from the background before officially downloading a new screen saver from the background, wherein the information data of the screen saver stores information related to the screen saver to be downloaded. For example, the download address data in the information data stores the download address of the screen saver to be downloaded. For example, the position data in the information data stores the position of the screen saver to be downloaded when it is displayed on the display device.

[0072] S2: Read the information data of the screen saver that has been saved locally from the target file stored locally;

[0073] The information of the screen saver that has been downloaded and stored locally is also stored in the information data of the corresponding screen saver, and the information data is stored in a local file. The file for storing the information data of the local screen saver locally is referred to as the target file in this article. The information data of the screen saver stored locally also includes the download address data of the screen saver and the location data of the screen saver.

[0074] S3: processing the target file according to the information data of the screen saver to be updated and the information data of the screen saver stored in the target file;

[0075] This step compares the relevant information of the screen saver to be downloaded with the locally saved screen saver before downloading, and processes the target file based on the comparison. Since the information data contains position data, the positional relationship between the two can be determined by comparison, and the processing method of the target file is also related to the target file.

[0076] S4: updating the screen saver file stored locally according to the processed target file and the information data of the screen saver to be updated.

[0077] This embodiment can determine the relationship between the screen saver to be updated and the screen saver file currently stored locally through the processed target file and the information data of the screen saver to be updated, and then determine the specific operation on the local screen saver file according to the aforementioned relationship. In this way, the new screen saver file can be downloaded in time, and repeated downloading of the same screen saver file after the user modifies the location can be avoided.

[0078] like Figure 2 As shown, as an example, in this embodiment, the step S3: processing the target file according to the information data of the screen saver to be updated and the information data of the screen saver stored in the target file also includes:

[0079] S31: Determine whether the information data read from the target file is empty;

[0080] S32: if it is empty, storing the information data of the screen saver to be updated into the target file;

[0081] If the information data read from the target file is empty, it means that the screen saver has not been downloaded from the background before, so the information data related to the screen saver saved in the target file is empty. At this time, since there is no possibility of repeated downloading, there is no need to compare and analyze the information of the previously saved screen saver, and the information data of the screen saver to be downloaded obtained from the background can be directly recorded in the target file.

[0082] S33: If it is not empty, operate the information data in the target file according to the information data stored in the target file and the information data to be updated.

[0083] If the information data in the read target file is not empty, it means that the screen saver has been downloaded from the background and saved locally. Therefore, this step compares and analyzes the information data of the downloaded screen saver and the information data of the screen saver to be downloaded, and then performs further operations on the information data saved in the target file based on the specific comparison and analysis results.

[0084] like Figure 3 As shown, in this embodiment, the S33: if it is not empty, operating the information data in the target file according to the information data saved in the target file and the information data of the screen saver to be updated also includes:

[0085] S331: Acquire the data length of the information data stored in the target file as the first data length;

[0086] S332: Acquire the data length of the information data of the screen saver to be updated as the second data length;

[0087] The data length in this embodiment refers to the size of the space occupied by the data, and the data length can be expressed in bytes or bits.

[0088] S333: Determine whether the first data length and the second data length are the same;

[0089] S334: If the lengths are the same, the information data currently stored in the target file is replaced with the information data of the screen saver to be updated;

[0090] If the data length of the information data read from the target file is the same as the data length of the information data obtained from the background, it means that the two data are exactly the same. At this time, there is no need to save new data. Therefore, the operation on the information data in the target file is to keep the existing information data in the target file unchanged.

[0091] S335: If the lengths are different, the information data read from the target file is compared with the information data of the screen saver to be updated, and the information data in the target file is operated according to the comparison result.

[0092] If the lengths of the two information data are different, it indicates that there are certain differences between the information data read from the target file and the information data obtained from the background. You can further compare the two information data before performing any operations.

[0093] like Figure 4 As shown, in this embodiment, S335: if the lengths are different, the information data stored in the target file is compared with the information data of the screen saver to be updated, and the information data in the target file is operated according to the comparison result, and further includes:

[0094] S3351: Compare whether the information data read from the target file and the information data obtained from the background are exactly the same;

[0095] During specific implementation, the information data read from the target file and the information data obtained from the background can be compared one by one.

[0096] S3352: If yes, keep the information data in the target file;

[0097] If the information data read from the target file is exactly the same as the information data obtained from the background, it indicates that the screen saver to be downloaded is the same as the screen saver already saved locally, so there is no need to download it again. The operation on the information data in the target file is to keep the information data in the target file unchanged.

[0098] S3353: if otherwise, compare the position data and non-position data of the information data read from the target file with the information data obtained from the background;

[0099] The non-position data refers to other data in the information data except the non-position data. If the information data read from the target file and the information data obtained from the background are not exactly the same, it is necessary to further analyze the similarities and differences between the position data and the non-position data in the information data read from the target file and the information data obtained from the background.

[0100] S3354: Operate the information data in the target file according to the comparison result of the position data and the non-position data.

[0101] By comparing the position data with the non-position data, it can be known whether the local screensaver is different from the screensaver to be downloaded only in position. If so, it indicates that the position of the locally saved screensaver has been modified by the user.

[0102] like Figure 5As shown, in this embodiment, the S3354: operating the information data in the target file according to the comparison result of the position data and the non-position data also includes:

[0103] S33541: Keep the information data in the target file if the non-position data is the same and the position data is different;

[0104] If the non-position data is the same and the position data is different, it indicates that the screen saver to be downloaded is the same as the screen saver content saved locally but in a different position, and does not need to be downloaded repeatedly. Therefore, the operation on the target file is to retain the information data in the target file.

[0105] S33542: If the non-position data is different, the information data currently stored in the target file is replaced with the information data obtained from the background.

[0106] If the non-position data is different, it indicates that the screen saver waiting to be downloaded from the background is different from the screen saver currently saved locally, so the operation on the target file is to replace the current information data in the target file with the information data newly obtained from the background.

[0107] like Figure 6 As shown, in this embodiment, the step S4: operating the screen saver file stored locally according to the processed target file and the information data of the screen saver to be updated also includes:

[0108] S41: Obtain the download address, file name and MD5 value of the screen saver to be downloaded according to the information data in the target file;

[0109] MD5 stands for MD5 Message-Digest Algorithm. This algorithm is a widely used cryptographic hash function that can generate a 128-bit (16-byte) hash value to ensure the integrity and consistency of information transmission. It is mainly used for data encryption.

[0110] The information data of the screen saver to be updated obtained from the background includes the MD5 value, so the information data in the target file after the update process also includes the MD5 value of the screen saver to be downloaded.

[0111] S42: Determine whether the file name of the screen saver to be downloaded is the same as the file name of the screen saver stored in the local target folder;

[0112] S43: if the file names are not the same, downloading the screen saver file from the background according to the download address;

[0113] If the file names are different, it indicates that the file to be downloaded is a new screen saver file, so the screen saver file is downloaded according to the download address.

[0114] S44: if the file names are the same, then comparing the MD5 value of the screen saver to be downloaded with the MD5 value of the screen saver stored in the local target folder;

[0115] If the file names are the same, it is necessary to further compare the MD5 value of the screen saver to be downloaded with the MD5 value of the screen saver stored in the local target folder.

[0116] S45: If the MD5 value of the screen saver to be downloaded is the same as the MD5 value of the screen saver stored in the local target folder, the screen saver file is not downloaded from the background and the screen saver file stored in the local target folder is retained;

[0117] If the MD5 values ​​of the two are the same, it indicates that the screen saver to be downloaded is the same as the screen saver currently stored locally. In this case, there is no need to download it again. Therefore, the operation on the screen saver file stored locally is to retain the screen saver file stored in the local target folder.

[0118] S46: If the MD5 value of the screen saver to be downloaded is different from the MD5 value of the screen saver stored in the local target folder, the screen saver file is downloaded from the background and the screen saver file stored in the local target folder is replaced with the downloaded screen saver file.

[0119] If the MD5 values ​​of the two are different, it indicates that the screen saver to be downloaded is different from the screen saver currently stored locally, so the screen saver file needs to be downloaded from the background installation download address. At this time, the operation on the screen saver file stored locally is to replace the screen saver file stored in the local target folder with the downloaded screen saver file.

[0120] like Figure 7 As shown, this embodiment allows the user to set the location of the screen saver downloaded to the local computer. The method of this embodiment also includes:

[0121] S01: Obtaining information about the location change of the screen saver stored in the local target folder by the user;

[0122] S02: Modify the position data in the target file according to the position change information.

[0123] This embodiment modifies the location data of the target file according to the information about the screen saver position change by the user. Thus, before downloading, the screen saver update method is determined by comparing the information data of the screen saver to be downloaded with the location data in the target file. Therefore, the screen saver update is not affected by the user's modification of the screen saver position.

[0124] like Figure 8 As shown, in this embodiment, the S1: obtaining information data of the screen saver to be updated from the background, the information data including the download address data of the screen saver and the location data of the screen saver also includes:

[0125] S11: monitor network connection signal;

[0126] S12: When a network connection signal is detected, information data of the screen saver to be updated is obtained from the background.

[0127] This embodiment automatically obtains information data of the screen saver to be updated from the background after detecting the network connection signal, so that the screen saver can be updated in time.

[0128] In this embodiment, the step S46: if the MD5 value of the screen saver to be downloaded is different from the MD5 value of the screen saver stored in the local target folder, then downloading the screen saver file from the background according to the download address and replacing the screen saver file stored in the local target folder with the downloaded screen saver file also includes:

[0129] S461: Obtaining a preset rule for dividing screen saver files;

[0130] For example, when the screen saver is an image file, the screen saver file can be divided according to the rule of image area division. When the screen saver is an animation file, the screen saver file can be divided according to the rule of animation file frame division.

[0131] The screen saver file is divided into multiple logical blocks (such as image files are divided into different partitions, animation files are divided into different frames). During the background data comparison, only the changed file blocks are identified, and the changed blocks are downloaded and updated separately.

[0132] S462: Divide the screen saver file to be downloaded into a plurality of first logic blocks according to a preset rule;

[0133] For example, when the screen saver is an image file, each area of ​​the image is a different first logical block. When the screen saver file is an animation file, each frame is a different first logical block. The screen saver file can be uploaded to the network end according to the pre-divided first logical blocks.

[0134] S463: Divide the screen saver file stored in the local target folder into a plurality of second logic blocks according to the preset rule;

[0135] The division method of the local screen saver files is the same as the division method of the screen saver files to be downloaded.

[0136] S464: Calculate the hash value of each first logic block;

[0137] S465: Calculate the hash value of each second logic block;

[0138] The aforementioned method for calculating the hash value of a file may adopt existing technology and is not limited here.

[0139] S466: Compare the hash value of each first logic block with the hash value of each second logic block;

[0140] S467: Filter out the first logic blocks having hash values ​​different from those of the second logic blocks from the screen saver file to be downloaded for download;

[0141] This step compares the hash values ​​of each first logic block with the hash values ​​of each second logic block. If the hash value of the first logic block is the same as the hash value of some second logic blocks, it indicates that the screen saver file stored in the local target folder has the same content as the screen saver file to be downloaded, that is, the first logic block with the same hash value and the second logic block have the same content. When downloading, only the first logic block with the same content as the local screen saver in the screen saver to be updated is downloaded.

[0142] In order to enhance the user experience, customers are allowed to personalize the screen saver's running effects. For this purpose, the screen saver file installation and running effects can be processed to obtain the running effects set by the user, such as adjusting the transparency of the screen saver, changing the size of the screen saver icon, rotating and scaling the screen saver icon, and making the screen saver image move along a predetermined trajectory.

[0143] If the processing is performed according to the running results after all the first logic blocks are downloaded, the user's waiting time will be prolonged. In this regard, the method further includes:

[0144] S4671: Determine the downloading order of the first logical block to be downloaded according to the execution effect of the screen saver file;

[0145] In this step, the first logic block that needs to be downloaded before being processed according to the effect is placed in front of the download sequence.

[0146] S4672: Download the first logic block in sequence according to the downloading order, and process the reserved second logic block and the downloaded first logic block according to the execution effect of the screen saver file.

[0147] This step can be performed while downloading so as to process the downloaded logic blocks, thereby eliminating the need to wait until all first logic blocks are downloaded before processing.

[0148] S468: Filter out the second logic block having the same hash value as the first logic block from the screen saver file stored in the local target folder and retain it, and delete the remaining logic blocks;

[0149] In this step, the same part of the screen saver file stored in the local target folder as the screen saver file to be updated is retained, and the different part is deleted.

[0150] S469: Merge the downloaded first logic block and the retained second logic block into a complete screen saver file and save the file in a local target folder.

[0151] This step completes the update of the screen saver file by merging the downloaded screen saver with the retained screen saver. By adopting the solution of this embodiment, only the changed part of the screen saver file can be updated to save bandwidth and storage resources, thus greatly reducing resource consumption during the screen saver update process, and is particularly suitable for the update of large screen saver files, avoiding the problems of data redundancy and excessive update time caused by overall replacement.
