In the step (i), the music database search of the song cycle period may include: (k) inputting a search word of a song related to the character code into the search database; (l) setting an identifier of a character associated with the search word; (m) extracting a representative character associated with a search word of the song; (n) comparing the identifier with the representative character; (o) classifying a song name to be searched for by identifier if the identifier and the representative character are the same in step (n); (p) determining whether there are any more songs to classify; (q) if it is determined in step (p) that there are no more song names to classify, sorting the classified song names in binary tree form for each typewriter to create a database.

According to an embodiment of the present invention, the user can search for a song to be found by writing the search word of the song to be found in the song cycle period directly to the input unit of the handwriting input song searcher. It is possible to provide an easy and convenient way of searching for songs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a flowchart sequentially illustrating a search method in a handwriting input song searcher among song search methods in a karaoke cycle using handwriting input according to the present invention.

3A is a block diagram schematically showing the configuration of a song search system to which a song search method of a karaoke period using the handwriting input according to the present invention is shown, and FIG. 3B shows the configuration of the handwriting input song searcher of FIG. 3A. 3 is a detailed block diagram illustrating the input unit of FIG. 3B, and FIG. 3D illustrates a detailed block diagram of the music recording cycle of FIG. 3A. Is shown.

Referring to each of these drawings, according to the present invention, the song search method of the song group cycle using the handwriting input, first, the user in the standby mode of the touch screen 30b of the handwriting input song searcher 30, for example, with a pen or finger; The specific mode is selected through the input unit 30a provided in the touch screen 30b.

Here, the specific mode is selected from the input keys 32, 33, 34 of Korean, English, and numbers. In the handwriting input song searcher 30, ← is a delete key 35 to delete the entered letters and numbers, and → is a space key 36 with a space function. Completion is an input completion key 37, and reference numeral 31 is a handwriting input panel unit.

Subsequently, a handwriting input is performed on the handwriting input panel unit 31 provided on the input unit 30a with the search word of the song to be searched for in the song cycle period 10 (step 120).

For example, Korean is selected from the input keys, and the word 'dong' is written in the input panel unit 31.

As described above, the input data of the handwritten input search word is preprocessed, and the input character of the search word is read (step 130).

That is, when the writing input is started, the electronic signal is extracted from the touch sensor of the touch screen 30b to perform a preprocessing operation of removing unnecessary data from the input data. Then, the input character is read.

In step 130, it is determined whether the reading of the input character is successful (step 140).

If the character reading is successful in step 140, the character closest to the input character is extracted and code conversion of the extracted character is performed (step 150).

That is, after reading the character, the character that is a model is compared in advance in the learned training database (DB) 30e, and the closest character is extracted, and the extracted character is subjected to KSC5601 code conversion in the case of code conversion, for example, Hangul.

In step 150, it is determined whether the character code conversion is successful (step 160).

If the character code conversion is successful in step 160, the control unit 30c of the handwriting input song searcher 30 transmits the character code to the singing cycle period 10 through the wireless transceiver 30d (step 170).

In this case, the wireless transmission is performed by using the wireless transceiver 30d of the handwriting input song searcher 30 and the wireless transceiver 10a of the music recording period 10, respectively.

Since the wireless transmission and reception is applied at a short range, for example, any one of wireless communication methods such as Bluetooth, wireless local area network (LAN), infrared communication (IrDA, Infrared Data Association), and RF (Radio Frequency) can be used. You can do it by selecting.

As described above, the song search method using the handwriting input according to the present invention after the song search word by the handwriting input from the handwriting input song searcher 30 through the wireless communication method will be described.

4 is a flowchart sequentially showing a search method in a song cycle among song search methods of a song cycle using handwriting input according to the present invention.

Referring to FIG. 4, the song code period 10 receives the character code transmitted in step 170 by using the wireless transceiver 10a. (Step 210).

The received character code is stored in the internal memory 10ba of the controller 10b, and the controller 10b searches for a song in the music database DB of the song group 10 by referring to the received character code. (Step 220)

If the song search is successful in step 220, the control unit of the singing cycle period 10 sends it to the image processing unit 10d so that it can be output on the screen of the display 20, the list of songs found on the screen of the display 20 Is displayed (step 230).

That is, in the song group cycle 10, the song title database (10) can be quickly searched for the song title in real time by using the received character code. Accordingly, the grain database (DB) 10c is previously configured by the above method (steps 210 to 230) to find the input code value, and to display it on the screen of the display 20.

In particular, the search method of the music database of the song cycle period 10 of step 220 will be described in more detail.

FIG. 5 is a flowchart sequentially showing a song searching method in a song database of a song cycle in a song search method using a handwriting input according to the present invention.

The search method of FIG. 5 is an algorithm for classifying song names and singer's names for all contents.

Referring to FIG. 5, first, a search word of a song related to a character code is input to the music piece database 10c.

Subsequently, an identifier of a character related to the search word is set.

In case of Hangul, Identifier, id_string [] = {"" "," I "," Dah "," La "," M "," Bah "," Sa "," A "," Za "," Cha ", "Car", "ta", "wave", "lower"}, and in English, identifier = {"A", "B", "C", "D", "E", "F", "G "," H "," I "," J "," K "," L "," M "," N "," O "," P "," Q "," R "," S ", "T", "U", "V", "W", "X", "Y", "Z"}, if numeric identifier = {number: "0", "1", "2", " 3 "," 4 "," 5 "," 6 "," 7 "," 8 "," 9 "}

In addition, mjr_ch = music name representative character, id_idx = current identifier position, respectively.

The representative character associated with the search word of the song is extracted (step 330). That is, the representative character is extracted from the name of the song or the singer.

In addition, the identifier is compared with the extracted representative character {if (mjr_ch == id_string [id_idx])} (step 340).

If the identifier and the representative character are the same in step 340, the searched song names are classified by identifier.

It is then determined whether there are any more songs to classify (step 360).

If it is determined in step 360 that there are no more song names to classify, the sorted song names are sorted in binary tree form for each typewriter as shown in FIG. 6 (step 370), that is, the song names for all contents. And the singer names are sorted by identifier and the database is made in binary tree sorted form according to the sorted identifier.

Therefore, the database files are configured as shown in FIG. 6, sorted by the identifier by the representative character of the song name or the singer's name, and sorted in a binary tree form.

On the other hand, if the identifier and the representative character is different in step 340, as shown in Figure 6, after moving to the next identifier (id_idx ++) and compares the identifier and the extracted representative character again, the identifier of step 340 and Repeat until the representative character is the same (step 380).

That is, it moves to the next identifier (id_idx ++), compares it, and repeats the number of identifiers until the identifier and the extracted representative character are the same.

If it is determined in step 360 that there are song names to be further classified, the next song name is obtained, and the process is repeated from step 330 (step 390).
