Description

Semi-Automatic Audio File Searching Method

The present invention relates to a semi-automatic audio file retrieval method, and more particularly, to a semi-automatic audio file retrieval method that enhances the user's convenience by allowing a user to conveniently and conveniently retrieve a desired audio file among audio files stored in various recording media. .

As is well known, a method of searching an audio file stored in various recording media such as a CD or a DVD, an internal or external hard disk drive, or a flash memory. This method is used when the user knows in advance how to search the audio file stored in the recording medium and the user can play the audio files by using the playback commands such as "previous" and "next" while listening to the audio files. There may be a way to browse the file.

However, according to the first method of the conventional audio file searching method as described above, if the user knows in advance information such as the title, artist name, etc. of the audio file that the user wants to find, the user directly searches for the file stored in the recording medium. It is possible to see, but from the user's point of view, you cannot always know in advance the information about the audio file you are looking for, and even if you know the above information in advance, the information of the audio file stored in the recording medium is not well organized. If not, there was a problem that the usefulness falls.

Next, in the case of the second method described above, there is no need to manually operate the "Previous" or "Next" button again until the user finds the desired audio file among the many audio files stored in the recording medium. have. In particular, when such manual operation is required to perform important tasks related to the safety of the user, such as driving a car, it may be a significant threat to the safety of the user.

In order to solve the above-mentioned problems in the present invention, a semi-automatic audio file search that increases safety as well as user convenience by allowing a user to conveniently and conveniently search for an audio file desired by an audio file stored in various recording media. The purpose is to provide a method.

The semi-automatic audio file retrieval method of the present invention for achieving the above object is carried out in a player capable of reproducing an audio file stored in a recording medium, and when the semi-automatic search start command is inputted, partial reproduction of each audio file is performed. Performing a search while (a); If a semi-automatic search is currently being executed when a semi-automatic audio search end command is input, all of the steps (b) and (a) above play the audio file that has been partially played immediately from the beginning while the partial playback is stopped. When the search for the audio file is completed, step (c) is performed to perform a predetermined procedure.

In the above-described configuration, whether or not the search for all audio files is completed in the step (c) is a method of determining the completion of the search for audio files stored in the entire space of the recording medium, and the audio files stored in the current folder of the recording medium. And a method of determining the completion of the search for the audio files classified by the user's selection from among the audio files stored in the recording medium.

The partial playback may include a method of playing a portion of an audio file, a method of playing while jumping a portion of an audio file, a method of performing playback using a portion of information or a file provided from an audio producer or distributor, and the corresponding audio file. It is characterized in that it can be selected from the scheme using the compression reproduction technique.

In the step (c), the predetermined procedure may be selected from among no reproduction, reproduction from the first file, or reproduction of the last file.

According to the semi-automatic audio file retrieval method of the present invention, among audio files stored on various recording media, an audio file that a user wants to find can be easily retrieved using a smaller number of user commands (manual operation). Moreover, when applied to the car audio system, this technique can prevent the distraction of the user due to the search of the audio file, which can be very helpful for safe driving.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the semi-automatic audio file search method of the present invention.

1 is a flow chart illustrating a method for searching a semi-automatic audio file of the present invention, a software-based audio file having a general purpose processor such as an audio file player or a personal computer having a dedicated processor such as a portable MP3 player or a portable CD player. It may be ported to some function inside the player. As shown in FIG. 1, according to the semi-automatic audio file retrieval method of the present invention, first, if there is any user input in step S10 in a waiting state for user input, whether the user input is a semi-automatic search start command according to the present invention. In this case, the interface used for user input may include a "keyboard", "mouse", "remote controller", "touchpad", or "front panel of a car audio system".

As a result of the check in step S10, if the current user input is a semi-automatic search start command, the flow advances to step S20 to check whether the search of all audio files is completed. In this step S20, whether the search for all audio files is completed may vary depending on the settings of the corresponding player, but the following schemes may be used.

-Method of determining completion of searching for audio files stored in the whole space of recording media

-A method of determining the completion of the search for audio files stored in the current folder of the recording medium.

A method of determining completion of searching for audio files classified by user selection among audio files stored in a recording medium.

1, if the search for all audio files is not completed in step S20, the process proceeds to step S30 to select the remaining audio file, that is, the audio file to be partially played. Can be changed according to user settings. For example, it may be determined by the Hangul alphabetical order of the title or the singer, the alphabetical order, or the date order of storing (update) (including ascending or descending order) or some other order.

Next, in step S40, after performing partial playback on the selected audio file, steps S20 and below are repeated until all audio files have been searched. Partial playback can be performed by the following methods. have.

-Play a part of an audio file, for example, for 10 seconds at the beginning or 10 seconds at the middle

Playback of certain parts of an audio file while jumping for a predetermined time, that is, after playing a predetermined part for a predetermined time, and then playing for a predetermined time after jumping to the next part spaced apart in time

-When the information or file is provided from the audio producer or distributor, partial audio playback is performed using the information or file.

-A method of using a compression reproduction technique of the corresponding audio file, for example, a method of playing by using a fast-forward playback method or an audio summarizing method.

Returning to FIG. 1 again, if retrieval of all audio files is completed as a result of the check in step S20 while steps S20 to S40 are repeatedly performed, step S60 is performed. On the other hand, if it is determined in step S10 that the current user input is not a semi-automatic search start command, the process proceeds to step S50 to check whether the command is a semi-automatic search end command, and if the current user input is not a semi-automatic search end command. Next, the process proceeds to step S80 to perform the other selected function, whereas in the case of a semi-automatic search end command, step S60 is performed.

Next, in step S60, the semi-automatic audio search is terminated. First, when the search for all audio files is completed in step S20 and the semi-automatic audio search is terminated (case 1), the user cannot interpret the audio file as desired. There will be.

On the other hand, there may be a case where the user input in step S50 is "Semi-automatic audio search end" and thus terminates the semi-automatic audio search (case 2), if the command is not currently running the semi-automatic audio search, the command will be ignored, If a semi-automatic audio search is currently running, the currently running semi-automatic audio search will be forcibly stopped or terminated at the user's command. In this case, it may be interpreted that the user has found the desired audio file or does not intend to perform the semi-automatic audio search during the semi-automatic audio search.

Finally, in step S70, the audio file is played back. If the semi-automatic audio search is terminated in the above case 2, the most recently played audio file is the user unless the user intends to perform the semi-automatic audio search. Can be interpreted as the audio file that was being searched for, so that the most recently played part of the audio file is played from the beginning.

On the other hand, if you terminated the semi-automatic audio search by 1, the user may not be able to find the audio file that they want, so it can be interpreted as "no play", "play from first file", or "play from last file." Playback will be performed according to the settings of the device.

The semi-automatic audio file retrieval method of the present invention is not limited to the above-described embodiments, and may be modified in various ways within the scope of the technical idea of the present invention.
