However, due to the limited storage space occupied by the ID3 tag 101, as defined in the ID3 tag standard of the first version (ID3V1.0), it only occupies 128 bytes, and the information that can be stored is limited.
In addition, since the ID3 tag 101 is embedded in the MP3 file, if the content needs to be modified, the entire MP3 file needs to be read and parsed, and for different versions of the ID3 tag, it is in the MP3 file The location and content format of the file are different, and different analysis methods need to be used in a targeted manner, which increases the complexity of reading and modification, and makes it difficult to manage the associated information of the file

Embodiment Construction
[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0040] In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways than those described here, and those skilled in the art can make similar extensions without departing from the connotation of the present invention. Accordingly, the present invention is not limited to the specific embodiments disclosed below.
[0041] In the prior art, the ID3 tag inside the MP3 audio file is often used to store the associated information related to the file, but since the ID3 tag is embedded in the MP3 file, the complexity of reading and modifying is relatively high. Moreover, since the storage space it can occu...

The invention discloses a binding method of an object file and correlative information thereof and a correlative information searching method. The binding method comprises the steps of extracting the object file and the correlative information corresponding to the object file, and constructing an index file which is recorded with the correspondence between the object file and the correlative information. For the binding method, the correlative information corresponding to the object file and the object file are mutually independent and bound through the index file, thus reducing the complexity on modifying and reading, and the capacity of the stored information can be larger.
Description
technical field [0001] The invention relates to a method for binding a target file and its associated information and a method for searching for the associated information, in particular to a method for binding an audio file in MP3 format and its associated information and a method for searching for the associated information. Background technique [0002] With the development of multimedia information technology, since audio files in MP3 (Moving Picture Experts GroupAudio Layer III, moving picture expert compression standard audio level 3) format have excellent sound quality and take up less storage space, audio files in MP3 format and its players are widely used. While playing MP3 audio files, users often want to see some associated information related to the played file, such as the performer, composer, album name, release time, and lyrics of the song, so as to have a more comprehensive understanding of the file . [0003] The prior art generally solves the above proble...
