[0035] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the media file management method in this invention includes:

[0036] First, ensure that iTunes media management software is installed on your computer to generate import media names, which will be used to parse media library resource files later.

[0037] 101. Create the iTunes process;

[0038] iTunes is a free digital media player application for Mac and PC that manages and plays digital music and videos. It was launched by Apple Computer on January 10, 2001, at Macworld Expo in San Francisco. The iTunes program manages the content on Apple's iPod digital media player. In addition, iTunes can connect to the iTunes Store (if an internet connection is available) to download purchased digital music, music videos, TV shows, iPod games, various podcasts, and feature-length movies. Creating an iTunes process launches iTunes.

[0039] Optionally, the step of creating the iTunes process includes: querying the pre-installed registry to obtain the installation path of the pre-installed iTunes media management software; and creating the iTunes process according to the installation path. The media file management method creates the iTunes process in a suspended manner.

[0040] Specifically, the specific work steps for 101 are as follows:

[0041] 1011: Query the registry:

[0042] If the registry path HKEY_LOCAL_MACHINE\SOFTWARE\Classes\iTunes\DefaultIcon does not exist, execute 1012; otherwise, execute 1013.

[0043] 1012: Query the registry:

[0044] SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\AppPaths\\iTunes.exe;

[0045] 1013: Read the value of this registry key to obtain the installation path of iTunes;

[0046] 1014: Using the iTunes installation path obtained in 1011 as input, use WindowsAPICreateProcess to create the iTunes process in a suspended manner.

[0047] In the Windows API CreateProcess, the sixth parameter dwCreationFlags is set to CREATE_SUSPENDED.

[0048] 102. Obtain media information stored in the media library resource files in the pre-installed iTunes media management software, wherein the media information includes: raw data and version information corresponding to the raw data;

[0049] The media library resource file, also known as iTunes Library.itl, is the filename for the iTunes media management software. As the main database file of iTunes, it stores metadata information for various media (such as music, movies, TV shows, podcasts, etc.), and also includes playlists, album art, comments, and other data. Through the iTunes Library.itl file, users can quickly find the music and playlists they want to listen to. Furthermore, iTunes Library.itl supports interaction between iTunes and other applications.

[0050] 103. Add media information and / or delete media information to the original data to obtain the processed original data;

[0051] 104. Deserialize the processed original data to obtain deserialized data, and encrypt the deserialized data using the first key to generate encrypted data;

[0052] Deserialization is the process by which a client obtains a serialized object byte stream from a file or network, and then reconstructs the object based on the object's state and descriptive information stored in the byte stream. When two processes, one with iTunes media management software installed and the other with another device, need to communicate remotely, they can send various types of data, such as text, images, audio, and video. This data is transmitted over the network in binary sequence form, and Java serialization and deserialization are used to achieve the inter-process object transfer.

[0053] The reason for deserializing the processed raw data is that in network communication, data is often transmitted in serialized form for transmission across the network. The receiver needs to convert the serialized data back into objects or data for local use or further processing.

[0054] Serialization saves objects or data to disk, databases, or other persistent storage media. When this data needs to be read and used, the deserialization process restores it to the object or data in memory. In distributed systems, different nodes need to share data. By serializing data and transmitting it over a network, data can be easily transferred between different nodes, and the receiving end can then use deserialization to restore the data to a usable object or data. In short, deserialization is the process of converting serialized data back into the original object or data, facilitating data transfer, persistent storage, and data sharing in distributed systems.

[0055] 105. Compress the encrypted data to obtain compressed encrypted data, and concatenate the compressed encrypted data according to the version information corresponding to the original data to generate a new media library resource file.

[0056] The new media library resource files can be imported to other devices or local storage.

[0057] The compressed encrypted data is concatenated, that is, the header version information is concatenated with the compressed encrypted data. In the above process, the version information is not processed.

[0058] Please see Figure 2 , Figure 2 In a second embodiment of the media file management method of the present invention, the following steps may be performed in step 102:

[0059] 1021. Parse the media library resource files to obtain the compressed raw data;

[0060] 1022. Decompress the compressed raw data to obtain decompressed data;

[0061] 1023. Based on the preset second key, perform AES decryption on the decompressed data to obtain the original data.

[0062] In steps 1021-1023, since the media information consists of version information and compressed information, to obtain and parse the media information content, the compressed raw data must first be decompressed. The decompressed raw data is AES encrypted. The raw data storing the media information needs to be parsed using the second key. After these steps, media information can be flexibly added to and / or deleted from the raw data. AES encryption is a very powerful encryption algorithm that can be used to ensure the security of raw data transmission. Its security can be measured by its key length; a 128-bit key can resist most attacks, while 192-bit and 256-bit keys can resist all attacks. Therefore, the AES encryption algorithm provides very high security. Decompressing the compressed raw data saves storage space. Raw data compression involves compressing the raw data using a compression algorithm, reducing the storage space occupied by the raw data and thus saving storage space. During the transmission and storage of raw data, compressing the raw data can reduce transmission and storage time and costs, and improve transmission and storage efficiency.

[0063] Compressing raw data involves encrypting it with a key to protect its security. During transmission and storage, encrypted compressed raw data prevents unauthorized access and tampering, protecting its integrity and confidentiality. Compressed raw data also facilitates management and backup. In media file management, compressed raw data facilitates backup and recovery. During raw data transmission, compressed raw data reduces the amount of raw data transmitted, simplifying management and transmission.

[0064] In this embodiment, after obtaining the media information stored in the media library resource file in the preset iTunes media management software, and before adding and / or deleting media information to the original data to obtain the processed original data, the method further includes:

[0065] 1024. Read the storage format of the decompressed data, wherein the storage format includes: a feature field of media information, the feature field corresponding to the media name.

[0066] In step 1024, the decompressed data has a certain storage format, and some characteristic fields explicitly indicate that media information is stored. The data needs to be parsed out according to the decompression data storage rules. The storage format has the following uses when decompressing data:

[0067] Data compression: Storage formats can compress raw data, reducing the storage space it occupies. By using compression algorithms, data can be compressed into a smaller size, thus saving disk space or network bandwidth. During decompression, the storage format can restore the compressed data to its original format.

[0068] Data transmission: Compressing data using storage formats reduces its size during network transmission, thereby improving transmission efficiency. Smaller data volumes can be sent and received faster, reducing transmission latency and lowering network bandwidth requirements.

[0069] Speed ​​optimization: Some storage formats can offer faster processing speeds during decompression. By employing efficient algorithms and data structures, storage formats can accelerate data decompression, thereby improving the efficiency of data reading and processing.

[0070] Cross-platform compatibility: The storage format provides cross-platform compatibility, enabling different operating systems, programming languages, or applications to parse and process the same compressed data. This compatibility makes data sharing and transfer in different environments more convenient and reliable.

[0071] Data protection: Certain storage formats can provide protection for data integrity and security. By adding mechanisms such as checksums, digital signatures, or encryption, storage formats can prevent data from being tampered with or accessed during transmission or storage.

[0072] The appropriate storage format needs to be selected based on the specific application scenario and requirements in order to balance the requirements of compression ratio, decompression speed and compatibility.

[0073] In this embodiment, the feature fields include: music name, playlist, video, and home theater; different feature fields can be used to process the raw data in different ways, making media file management more flexible.

[0074] Specifically, the following steps can be performed in step 103:

[0075] 1031. When the feature field is a music name, add a music media information block to the original data and update the statistical value synchronously to obtain the processed original data, wherein the statistical value is the value of adding or reducing media information.

[0076] Specifically, the following steps can also be performed in step 103:

[0077] 1032. When the feature field is a music name, delete a music media information block from the original data and update the statistical value synchronously to obtain the processed original data.

[0078] In this embodiment, the media information also includes cover data and comment data corresponding to the original data.

[0079] In this embodiment of the invention, the method of processing the raw data can help users manage media resources on the iTunes media management software. Even if there are many media files in the iTunes media management software, the data media files can be successfully parsed, and other media files can be imported to other devices or local storage so that the music can be played offline or on any other terminal device that supports audio playback.
