The present invention designates an important playing section and playing time in an audio file, so that an audio file can be quickly searched and edited through the playing section and time when searching for an audio file. File structure and audio file playback method.

Recently, as the memory capacity of a terminal has increased, the number and capacity of files that can be stored in the terminal have greatly increased. Therefore, when the terminal seeks to find and play a specific file, a function of searching for the file to be searched at high speed is required.

In the case of still images such as JPEG, thumbnails can be used to view the reduced image without having to decode (decode) the entire image. The entire contents can be roughly known through the reduced image.

The thumbnail function is to reduce all images in one directory to a small nail shape so that they can be viewed as albums. The thumbnail function may be used to search and find a desired image at a glance among a plurality of whole images. That is, using the above function, it is easy to find the necessary image when there are many image files.

However, unlike video, audio files are not displayed visually, so you have to listen to a part of the file to find a desired file. At this time, the contents of the entire file can effectively express the contents of the entire file so that the efficient search of the audio file is possible.

That is, in order to search for a desired audio file among a plurality of audio files, a method such as a thumbnail function in an image is required in the audio file. In other words, the audio file is required to play a part of the file to grasp the contents of the entire file.

In general, during the high-speed search of audio files such as MP3 and OGG, only the beginning of music is decoded and output. However, typically an important part of an audio file is not at the beginning of the file, but at the middle of the file.

Therefore, when reproducing only the playing portion of the audio file when searching for the audio file, it is difficult for the user to find the audio file to be searched.

That is, in order to solve this problem, it is efficient to search a file by playing an important part of the audio file to be searched.

 In addition, in the case of audio files with long description, understanding, speech, or other playing time, in order to search and understand the content, the entire playing section must be played and listened to, so that the quick search is difficult, and the entire playing section is heard and the whole is understood. It takes a lot of time.

Therefore, a function for editing or summarizing only a portion providing a function such as a plot of the audio file is required.

1 is a diagram illustrating a structure of a conventional audio file.

As shown in FIG. 1, the conventional audio file has an audio file structure consisting of only the entire playing section 10.

Therefore, when searching for a specific audio file among a plurality of audio files, a method of reproducing and searching only the playing start section 11 of the entire audio file has been used.

However, the main feature of the audio file mainly appears in the important player 12 which is the middle part of the file, and it is efficient to grasp the contents of the file through the important player 12.

That is, the performance of the audio file to be searched in the performance start section 11 is hard to appear effectively, and the contents of the audio file only through the performance start section 11 due to the waiting time without the audio output before playing the audio file. It takes a lot of time to figure out and determine whether it's the file you want.

An object of the present invention is to propose a file structure and an audio file reproducing method for a high-speed search and editing function of an audio file capable of easily and quickly searching a specific audio file among a plurality of audio files.

In addition, the file structure and audio file playback for a fast search and edit function of the audio file that allows the user to quickly find the desired section among a plurality of files or a long playing time through the editing and summary of the audio file It aims to propose a method.

The file structure for the high-speed search and edit function of the audio file according to the spirit of the present invention is the entire playing section of the audio file, the number of important performances recorded when the number of important parts played on behalf of the file when the audio file is searched; It includes an important performance portion in which the main features of the audio file are expressed.

In addition, in the audio file reproducing method according to the spirit of the present invention, the step of requesting audio file reproduction for a storage medium in which a plurality of audio files are stored, and important playing interval information indicating a characteristic of each audio file stored in the storage medium; Acquiring a sequence, reproducing an important performance section of each audio file sequentially with reference to the obtained important performance section information, and reproducing an entire performance section of an audio file selected by a user at the time of playing the important performance section; Step is performed.

In addition, the audio file reproducing method according to the spirit of the present invention reduces the file retrieval time by preferentially reproducing an important performance portion in which the main characteristics of the audio file are expressed, rather than the entire playing section, during the audio file retrieval.

In addition, the audio file storage medium according to the spirit of the present invention includes a first area containing the entire playing section of the audio file, a second area containing the important playing section information indicating the characteristics of the audio file, the number of information of the important playing section It includes a third region recorded.

The present invention has the effect of suggesting a file structure and an audio file reproducing method for a high speed search and editing function of an audio file that can easily and quickly search for a specific audio file among a plurality of audio files.

In addition, the file structure and audio file playback for a fast search and edit function of the audio file that allows the user to quickly find the desired section among a plurality of files or a long playing time through the editing and summary of the audio file It is effective to propose a method.

As the storage space of the terminal is increased, a large number of audio files can be stored in the terminal, thereby requiring a function of quickly searching for an audio file to be searched for. Therefore, the file structure having the audio file fast search and editing function is composed of the number of important performances and the important performance parts together with the original audio file as shown in FIG.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments set forth below, and the scope of the invention will be presented by the addition, limitation, deletion, addition, etc. of components within the scope obvious to those skilled in the art to which the present invention pertains. Could be.

2 is a diagram illustrating an audio file structure according to the spirit of the present invention.

As shown in FIG. 2, the audio file according to the spirit of the present invention includes an important performance number 100, an important performance part 110, and an entire audio section 120.

In the total number of important performances 100, the number of portions of one audio file which the user considers to be important is recorded.

One part can be selected and recorded as the important part, and a plurality of parts can be selected and recorded.

When the total number of important performances 100 is one, only the important performance part 110 of the audio file is decoded and played to increase the sense of speed when searching for the audio file.

That is, when a quick file search is required, the important performance part 110 is decoded and played in the entire audio file.

In the important performance part 110, a part of an audio file corresponding to the number of the important performances 100 is recorded. Each playing section recorded in the important playing section 110 may have a different file size and playback time. This is because, when the user selects and edits each important part, the size and playback time of the file vary depending on how many parts are selected and edited.

The important performance part 110 is configured to include an important performance part start position and an end position corresponding to the important performance part of the entire audio file, and play from the important performance part start position to the end position when a user searches for an audio file. This can speed up the search.

In addition, the important performance part 110 may be configured to include a start position of a file corresponding to an important performance part of the entire audio file and a playing time lasting from the start position. In this case, the speed of the search can be increased by playing the audio file for the set duration from the start position of the important performance part.

The entire audio file playing section 120 may have a file format such as MP3, WMA, OGG, RM, etc., but may not be limited thereto and may have various file formats for outputting a voice signal.

The MP3 (MPEG Audio Layer-3) refers to a compression scheme designed to effectively use an audio signal, and is a file format that can reduce the size of data to more than one tenth while maintaining CD-quality sound.

The MP3 uses a method of compressing by deleting unnecessary data. With this compression method, after compressing the sound, it is difficult to restore it to its original shape, but the compression rate is considerably high.

The WMA (Windows Media Audio), which is a voice compression format of Microsoft's Windows Media Technologies 4.0 technology, supports streaming and shows a compression rate that can reduce a voice file to half the capacity of an MP3.

In addition, it has a built-in copyright protection technology 'Windows Media Rights Manager' and a playback player is built into the Windows operating system.

The OGG is a new kind of digital music format that was created against the charge of MP3, and a series of volunteers will replace MP3 with a focus on Christopher Montgomery, a 1998 student from MIT, USA, who announced that Fraunhofer Institute will charge MP3. It was studied as.

The OGG can make music files through music CDs as well as MP3s, and can listen to music through existing MP3 playback programs such as WinAmp. In addition, it has better sound quality than MP3, but averages 38% less capacity than MP3 files.

The RM is a multimedia streaming data file used in a Real player of Real Network Corporation. The RM is used to watch and listen to radio, TV, video, etc. in real time through the Internet. In the past, audio and video were separated, but in a new playback program called RealPlayer G2, all content is integrated.

On the other hand, in the case of an audio file having a long playback time, that is, a speech, a description, etc., a function for editing the entire contents is required. As shown in FIG. 2, when the user selects an important part to be edited in the entire audio file playing section 120, the audio file may be edited using only the part selected by the user without modification of the original audio file.

The most important part of the audio file may be defined as a key playing position and a playing time played from the key playing position. If the important part is designated through the editing function, the user can easily grasp the file contents without searching the entire contents of the audio file when searching for a plurality of audio files. That is, the desired music file can be searched more accurately and quickly from the entire music file.

In addition, using the editing function, a medley function can be implemented. The medley function is a technique of playing important parts of several songs by connecting them to each other and can be made by selecting and editing a part of several audio files that a user wants to hear by connecting them.

If the number of important performances 100 is greater than 1, the audio file has the same important performance portion 110 as the number of important performances 100. When there are a plurality of important performance parts 110, the important performance parts 110 are played according to the priority of each playing section set by the user.

That is, when searching for an audio file including a plurality of important performance parts 110, playback is performed according to the priority of the important performance part 110 designated by a user, and the reproduction of the audio file rather than the entire performance section 120 is performed. By preferentially reproducing the important performance part 110 in which the main features are expressed, the file search time can be shortened.

3 is a diagram illustrating an embodiment of an audio file structure according to the spirit of the present invention.

As shown in FIG. 3, when the number of important performances 200 is 3, an important part of the audio file is played according to a priority set by a user. For example, when the user sets the important performance part 210 as three sections such as section 1, section 2, and section 3, and sets the superiority relationship between the sections as section 1> section 3> section 2, After playing section 1 and section 3, playback of section 2 is performed.

Using this function, the core section of a long audio file can be designated as a playing section, and simple editing is possible. This can be useful when you want to listen to some essential contents such as explanation and speech and to understand the plot.

The present invention can be widely used in an application for searching an audio file on a terminal having a large storage space. That is, it can be widely used for high speed music search, audio editing function or medley function.

The present invention has the effect of suggesting a file structure and an audio file reproducing method for a high speed search and editing function of an audio file that can easily and quickly search a specific audio file among a plurality of audio files.

In addition, a file structure and an audio file for a high speed search and editing function of an audio file, which enables the user to quickly find a desired section among a plurality of files or a long playing time through editing and summarizing the audio file. It is effective to propose a regeneration method.
