The present invention relates to a method of performing an automatic search (Search) function of an embedded video semi-permeable television, and more particularly, to add an automatic search function to an image accompaniment function of an embedded video semi-permeable television, and to store songs classified by genres in a memory. When the user selects the desired genre, only the songs corresponding to the selected genre among the plurality of songs stored in the memory are displayed on the screen, and the selected song number is inputted or selected so that the user can easily select the desired song. The present invention relates to a method for performing an automatic search function of a TV with a built-in half-cycle.

In general, a television may receive a video signal and an audio signal at the same time by receiving a radio signal transmitted from a broadcasting station, and an external signal input terminal for inputting a video signal and an audio signal from an external device may be installed. Video and audio signals from video cameras, camcorders and video accompaniment devices can be monitored by CRT and speakers. Therefore, the user can select and watch the video and audio signals input through the television signal or the external signal input terminal using the operation button or the remote controller installed in the television.

On the other hand, the video accompaniment device which is rapidly developed and marketed is a device that displays lyrics along with song accompaniment by connecting to a TV monitor, LD video accompaniment system using a laser disc player, and CDG image accompaniment using a cassette disc graphic player. It is divided into computer accompaniment system using system and memory.

By the way, LD video accompaniment system using laser disc player has the best image and sound quality than any sound source, but since only 30 songs are contained on a single laser disc, Juke Box can be used to service a large amount of songs. A disk changer such as In addition, the CDG image accompaniment system can provide the same sound quality as that of a laser disc, but only a limited number of still picture information recorded in a sub-code channel of a cult fact disc is used. In addition, the connection between the video and the music is not only deteriorated, and since the songs contained on the compact disc are limited to about 15 songs, there is a disadvantage in that a disc changer is required as in a system using a laser disc player. On the other hand, the computer accompaniment system cannot provide the same sound quality as the accompaniment system using a laser disc player and a compact disc graphic player, but it can provide a large amount of accompaniment information and lyrics information about 1,000 to 1,500 songs. There is an advantage that the selection can be made at high speed, which will be described schematically with reference to FIG.

FIG. 1 is a schematic block diagram of a computer accompaniment apparatus using a memory, which provides a stereo accompaniment signal and lyrics information and is used in connection with a general monitor and an audio amplifier. Referring to FIG. 1, when a specific song is selected by the command input unit 1 and an accompaniment start command is input, the control unit 2 controls the accompaniment signal generator 3 to generate an accompaniment signal of the specified song. To do that. At the same time, the controller 2 controls the text signal generator 4 to generate lyrics information of a specified song. The voice signal input through the voice input unit 5 is synthesized with the accompaniment signal by the synthesizer 6 and then provided to the audio amplifier through the audio output terminal, and the output of the text signal generator 4 is provided to the monitor so that the user You can sing along with the accompaniment.

However, the computer accompaniment device requires a separate monitor and an amplifier in order to effectively monitor the accompaniment signal and the lyrics signal.

Among the plurality of stored songs, the songs corresponding to the selected genre are automatically searched and displayed, the user inputs or selects the desired song number among the displayed genres of the displayed songs and performs the image accompaniment function, and the automatic search function Determine if you want to continue, continue If that is in that it includes the step of repeatedly performing the previous step to return to the step of selecting the desired genre.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a method for performing the automatic search function of the built-in video half-cycle TV according to the present invention will be described in detail.

3 is a flowchart showing a method of performing an automatic search function of a video half-cycle embedded television according to the present invention.

3, it is determined whether the image accompaniment mode is selected (S301). If the image accompaniment mode is not selected and performs the television mode (S302). If the image accompaniment mode is selected, it is determined whether the automatic search function is set (S303). If the auto search function is not set, the general accompaniment function is performed (S304). If the auto search function is set, the initial screen is displayed on the screen (S305). At this time, the initial screen is displayed with a list by various genres that the user wants to classify together with the background screen randomly set by the user's taste. The selection number for each genre is input (S306). At this time, the input of the selection number for each genre uses a numeric keypad mounted on a keyboard or a remote controller. When the input of the genre selection number is completed, the songs of the corresponding genre among the songs stored in the memory are automatically searched and the selected song number and title of the genre are displayed on the screen (S307). The user inputs a desired song number among the titles of the displayed song (S308). It is determined whether the input of the song number is completed (S309), and the input of the reserved song is not completed, and the process returns to the song number input step (S308). At this time, the number of digits of the number is arbitrarily set and compared with the number of digits of the song input by the user, and if it is equal to the set digits, it is set to determine that the song input is completed. Here, the method of selecting a song desired by the user may provide easier selection of the song by directly selecting the displayed state without inputting and selecting the song number. That is, the cursor is moved to the desired song by using the cursor position movement key in the displayed state, and when the movement is completed, the selection key is directly inputted. When the song input is completed, the microcomputer selects the corresponding song among the songs stored in the memory and displays it on the screen (S310). The user compares whether the displayed song is a desired song, and if it is a different song, inputs a cancel key (S311), and returns to step S307 of displaying a list of selected genres, and performs an image accompaniment function if the same song is performed (S312). ). If the song is not finished by determining whether the song is finished, it returns to the image accompaniment function performing step S312 and continues to perform the image accompaniment function, and determines whether to continue the automatic search function when the song ends. . If the automatic search function is not continued, all the processing ends, and if the automatic search function is continued, the process returns to the step of displaying the initial screen (S305) and repeats the entire process after the initial screen display step (S305).

To illustrate in more detail, an example is as follows.

It is determined whether the image accompaniment mode is selected. If the image accompaniment mode is not selected, the television mode is performed. If the image accompaniment mode is selected, it is determined whether the automatic search function is set. If the auto search function is not set, normal video accompaniment is performed.

If the auto search function is selected, the initial screen is displayed on the screen. In this case, the initial screen displays a list of titles selected by the user and divided into several genres. At this time, the state displayed on the screen is shown in [Table 1].

The user enters a number corresponding to the genre. For example, if the user wants to search by 'singer', the user inputs '6'. When the key input is completed, the microcomputer creates a list for each singer from a plurality of songs stored in the memory and displays it on the screen. The screen state at this time is shown in [Table 2].

When the user enters the number, the song sung by the singer of the number is searched from the memory and displayed. For example, when the user selects '2' and key inputs, the displayed state is shown in [Table 3].

Here, the song number is to use the song number already set. When the user finds a desired song and inputs a song number, it is determined whether input of the song number is completed. Here, in the method of determining whether the input of the song number is completed, the number of digits of the song number is arbitrarily set to determine that the key input is completed if the number of digits of the input number and the set digits are the same. At this time, the key input process is shown in [Table 4] to [Table 7].

When the key input is completed, the cursor _ is automatically removed to indicate that the key input is completed, and the microcomputer finds the song of the corresponding number and displays the song title on the screen.

Meanwhile, the user may select a song by inputting a number and directly select the song using the displayed state. That is, the displayed state is set as shown in [Table 8], the cursor is located at the corresponding song as shown in [Table 9] by using the cursor movement key, and the corresponding key can be selected by inputting a selection key.

Here, when the user inputs a selection key, the corresponding song is selected. The user checks whether the displayed song is a desired song, and if it is not a desired song, the user returns to the step of displaying a list of selected genres by entering a cancel key. If the cancel key is not input, the displayed song is determined to be the same as the song desired by the user, and the image accompaniment function is performed. If the song is not finished by determining whether the song is finished, continue with the video accompaniment function, and when the command is input to determine whether to continue the auto search function after the song is input, the initial screen is displayed. Repeat the entire process after that. On the other hand, if no command is entered to continue, the microcomputer automatically stops the automatic search function.

As described above, according to the method of performing the automatic search function of the built-in TV according to the present invention, in the video accompaniment function of the built-in TV, the music classified by genre is stored in the memory and the user selects a desired genre. Among the stored songs, only the songs corresponding to the selected genre are displayed on the screen, and the selected song number is inputted or an automatic search function is added to allow the user to directly select a desired song.
