Description

File name designation method for digital audio data {Method For Designation Of File Name For Digital Audio data}

The present invention relates to a file name designation method of digital audio data, and in particular, it is possible to specify digital audio data information in a file name and to distinguish a plurality of fields.

The most widely used reproduction system for digital audio data is the compact disc reproduction system. A typical compact disc stores about 1 to 2 hours of audio data, which is about 10 to 20 songs based on a song or pop song. When playing back the audio data stored in the compact disc, the serial number of the audio data currently being played is shown on the display section of the compact disc playback system, and the user recognizes the audio data currently being played through this number. As described above, the method of dividing the digital audio data by the serial number of the data is not particularly problematic when about 10 to 20 songs are stored in one CD.

However, if the compression technology of digital audio data is developed in the future and the cost of the recording medium becomes low, dozens or hundreds of digital audio data may be stored in one recording medium. In this case, it is very inconvenient to reproduce all the songs by the serial number only when the user wants to play the desired song.

Conventional compact discs as representative recording media of digital audio data have no additional information that can be provided to the user regarding the audio data stored by the recording method of CD-Digital Audio, which is a recording standard. When the user selects a song, only the track number is the only selection method.

However, if audio data is recorded in the file system, each piece of music can add additional information such as a song name, singer, genre, etc. into the file in the form of a tag added to the song or song. This recording method makes it possible to select and play back songs in a new manner according to various selections of the user, beyond the limitation of selecting songs only by the conventional track number. This depends on the fields that make up the additional information about the audio data. For example, when additional information about the singer and the genre is given to the stored audio data, the user can select and play only the songs of the desired singer or genre. This is especially useful if you have a lot of songs stored. In addition, such a category-specific playback can provide a user with a new service called a playback method by various various choices.

If a file compressed by MPEG Audio Layer III method (MP3 file) is contained in CD, the path table is read through PVD and the directory record is searched in the path table to read the ID3 tag containing additional information for classification. You should go to the file in the directory record and read the last sector. Therefore, assuming that the random access time is 100 ms, at least 500 ms is required. If it is assumed that 150 songs are stored on this CD, it takes about 75 seconds to search the entire song and make the classified information. This will be a big inconvenience for the user. Therefore, there is a need for a method for classifying and accessing information about data stored in a digital audio recording medium in a short time.

To this end, the present applicant in patent application No. 99-6058, when producing a recording medium of digital audio data, a database of additional information and location information about the digital audio data is created, stored in a separate file form, and reproduced. When the contents of the file are retrieved, a method of responding to the user's request for playback by classification is presented.

However, the method of storing in the form of a separate file has a disadvantage in that, whenever a new digital audio file is generated, an information file including additional information and location information about the digital audio data must be updated.

In the present invention, instead of storing the data in a separate file form as described above, a plurality of fields of information are specified in the file name of the digital audio data as a standard for the file name of the digital audio data, and the database can be used in a short time by using the information. To provide a file name designation method of digital audio data that can process desired information in a short time through retrieval.

In addition, an object of the present invention is to facilitate the classification and processing for each field without the need for a separate update process for information even when new digital audio data is generated.

The information processing includes a function for allowing a user to select and reproduce desired digital audio data.

1 is an example of file name designation of digital audio data according to the present invention;

In order to achieve the above object, in the present invention, the relevant information of the digital audio data is recorded in the file name, and each field recorded in the file name is distinguished by a delimiter, so that the digital audio reproduction system or other processing system can use the same information. It is intended to provide a standard of file name designation method of digital audio data that enables recognition and retrieval of delimiter.

Accordingly, in the file name designation method of the digital audio data according to the present invention, the relevant information of the digital audio data is recorded in the file name, and each field is recorded to be separated by a delimiter, and the relevant symbol is recognized to search for the related information. It is characterized in that the processing.

In the method for designating a file name of digital audio data according to the present invention, the delimiter is '[]' or '/' or '|' or '＼' or ',' or '{}' or '()' or It is characterized by being '<>'.

According to the file name designation method of digital audio data according to the present invention, not only is it easy to classify and process digital audio data files by recognizing the field of information recorded in the file name, but also when a new digital audio data file is generated, The file name designation method according to the present invention can be recognized and classified or processed by a playback system or other processing system as long as it conforms to the standard of the file name designation method.

Hereinafter, a file name designation method of digital audio data according to the present invention will be described with reference to the accompanying drawings.

1 is an example of file name designation of digital audio data according to the present invention.

1 shows an example of a file name designation method of an MP3 file, in which each field of information of digital audio data is recorded in the file name, and each field is identified by a delimiter '[]'. For example, a dance song of 'Pinkle' published in 1999, 'Eternal Love', would be '[Eternal Love] [Pinkle] [Dance] [1999] .mp3' according to the designation method shown in FIG. .

In addition to the fields of the digital audio data information shown in FIG. 1 as an example, other necessary fields such as [Composer], [Lyrician], etc. may be set and recorded.

According to the digital audio data having such a file name, the information of each field identified by the delimiter can be recognized and classified by the reproduction system in order to perform the processing for the reproduction method according to the user's request. In addition, desired processing after the retrieval can be performed.

Therefore, according to the designation method according to the present invention, the user can quickly extract and play only the songs of the desired field.

For example, if the user selects only a song published in 1999, the playback system searches only the [Year] portion of the fields of digital audio data information recorded in the file name, and classifies and reproduces only the [1999].

This music selection function is also possible for a plurality of fields. For example, if the user selects only the songs published by Finkle in 1999, the playback system first searches for [Artist] to extract [Finkle], and then searches for [Year] to extract the ones that are [1999]. do.

The designation method according to the present invention can be usefully used not only in the reproduction system but also in any system for managing digital audio data. For example, a system that functions to search for and categorize songs of a desired specification is a service that downloads only desired digital audio data upon user's order among a large number of digital audio data files. In this case, according to the designation method according to the present invention, retrieval and processing of digital audio data become very easy.

The method of designating a digital audio data file name according to the present invention is to present a standard of file name of digital audio data, and according to the standard, a server may use digital audio data based on such a standard in a system for playing or servicing a digital audio file. There is an advantage that can easily perform functions such as playback, sorting, listing.

As described above, the file name designation method of the digital audio data according to the present invention divides the information of the digital audio data by field into the file name itself, and the digital audio system recognizes and retrieves the information, thereby recording the recording medium. Even if a large amount of digital audio data is stored in the DVD, not only can be easily and quickly searched and reproduced or processed, but also when a new digital audio data file is generated, the standard of the file name designation method according to the present invention can be followed. Since it can be recognized and sorted or processed by a playback system or other processing system, there is an advantage that there is no need to update the database separately.
