Description

An apparatus and method for searching an audio file using a text input}

The present invention relates to a data retrieval apparatus and a retrieval method through a text input to enable a search for a desired type of music through a text input.

When recording MP3 music files on an optical disc (for example, a CD), typically about 170 songs or more can be recorded. In an optical disc in which MP3 songs are stored, when a user wants to search for a song, REW / FF Key 'or' Skip Key 'to check the songs one by one, so it is very cumbersome and time-consuming and inconvenient.

On the other hand, it is cumbersome to manually search for songs. If a user wants to search for songs through an intro playback operation, that is, playing only the first part of each song for a predetermined time (for example, 10 seconds). Even when there are a large number of MP3 songs recorded on an optical disc, this also has a long and inefficient problem.

Accordingly, the present invention has been made to solve the above problems, and provides a data retrieval apparatus and a retrieval method through a character input to enable faster and more efficient retrieval of a desired song through a simple character input. There is a purpose.

For each of the ▼, ◀, and ▶ keys, the first vowel is ㅏ) / numbers (0) / English (A) to display vowel / number / English in the following order sequentially, Allows the user to simply enter the desired character.

3 is a flowchart of a preferred embodiment of a data retrieval method through text input according to the present invention. Hereinafter, the data retrieval method of FIG. 3 according to the present invention will be described with reference to the configuration of FIGS. It explains in detail.

First, a plurality of MP3 music files are recorded on the inserted optical disc 10. In the 'Tag' of each MP3 music file, as illustrated in FIG. There are an Artist field, an Album field, a Comment field, a 4-byte Year field, and a 1-byte Genre field. An example of the dual genre field is shown in FIG. It was.

When the optical disc 10 is inserted and mounted in such a state, the microcomputer 70 detects the position information of each song from the header of each MP3 music file recorded on the optical disc 10, In addition, the tag section of each MP3 music file detects additional information (song name, singer name, .., genre, etc.) for each song (S10), and the position information and additional information of each detected song are converted to the corresponding song. The additional information is stored in the memory 71 in one-to-one association with the number (S11), and the additional information is detected when the MP3 music file is recorded on the optical disc 10 or when the recorded MP3 music file is requested to be played. 71).

In the state in which the additional information and the location information for each MP3 music file recorded on the optical disc 10 are stored in association with the corresponding song number in the memory 71, the user inputs the key input unit 80 to search for a song. When the 'character input mode' is selected (S20), the microcomputer 70 searches on the OSD 90 based on the data stored in the memory 71. The window will display the output.

Accordingly, the user designates a desired search form in the search box using the combination key button. For example, the user can designate a desired search form in the search box through the ▲ / ▼ key or the ◀ / ▶ key of the combination key button. After moving to, the desired search form is designated by pressing a selection key or a confirmation key of the combination key button.

When the user designates the search form as described above, the microcomputer 70 outputs and displays a text input window on the OSD 90 based on the data stored in the memory 71 (S21).

Accordingly, the user inputs a desired character in the text input window using the combination key button. For example, if the search type selected by the user is search for a singer name of ① and the user inputs 'strong' in the text input window. To input, press the ▲ key, which is the consonant key of the combination key button once, and then press the select key to select 'a', then press the ▼ key, which is the vowel key of the combination key button once, and then press the select key to ㅏ ', press the ▲ key of the combination key button eight times, then press the SELECT key to select' ㅇ 'and press the OK key, and' Strength 'is displayed on the text input window. When finally pressing the confirmation key of the combination key button, the microcomputer 70 determines that the character input is completed, and includes 'strong' based on the additional information stored in the memory 71. All the names of the artists are searched for and displayed on the OSD 90 of the search results of the type illustrated in FIG.

Therefore, after checking the search result displayed on the output, the user finds the desired singer name using the ▲ / ▼ key or the ◀ / ▶ key of the combination key button, and then selects the desired singer name through the selection key or the confirmation key of the combination key button. Accordingly, the microcomputer 70 searches all the song names for the selected designated singer name ('precipitation') based on the additional information stored in the memory 71 (S22). The search result is displayed on the OSD 90.

In this way, the user can search only the desired music files among the MP3 music files recorded on the optical disc 10 by simple text input. As described above, when the user searches for a singer name, the user enters a partial character (' If only the singer name including 'gang' is searched by inputting only 'strong', a song name for the selected singer name may be searched by selecting the desired singer name again from the searched singer names, but if the user inputs the singer name (' In the case where the entire 'precipitation' is inputted, all songs for the singer name ('precipitation') that have been directly inputted are searched, and the search result is displayed on the OSD 90 so that the searching time can be shortened.

In addition, the user may select a search for the song name of ② in the search box, and then search for a desired song by inputting some letters or the whole song name of the song through the text input window. When a character is input through a window such as 'Dan' or 'Dance' to search for a corresponding genre, for example, a dance song, the microcomputer 70 may genre of the song based on additional information stored in the memory 71. Searches for all songs corresponding to the dance and provides the result through the OSD 90.

In addition, it is possible to search various songs such as album and year through ④'s other search.

As described above, if a user requests an intro playback or a general playback operation of the searched song through the key input unit 80 (S30), the microcomputer 70 is stored in the memory 71. By moving to the start position of each song based on the position information of each song, the retrieved songs are read out sequentially, thereby reproducing the retrieved songs (S31).

However, if the user selects and selects a specific song from the searched songs using the combination key button of the key input unit 80, the microcomputer 70 sends only the selected and designated music from the searched songs to the optical disc 10. It reads from and performs playback operation.

The above-described preferred embodiments of the present invention are disclosed for purposes of illustration, and those skilled in the art can improve, change, and substitute various other embodiments within the technical spirit and scope of the present invention disclosed in the appended claims below. Or addition may be possible.

In the data search apparatus and the search method through the text input according to the present invention constituted as described above, when the user requests a song search through the text input, by using the additional information of each MP3 music file recorded on the optical disk It is a very useful invention that increases the convenience of the user and the efficiency of the device by quickly searching the corresponding songs corresponding to the input characters and immediately reproducing the retrieved songs at the request of the user.
