When the user selects the desired genre, the title and first measure of the song corresponding to the selected genre among the plurality of songs stored in the memory are displayed on the screen, and the accompaniment function of the first measure is performed. When it is completed, the title and the first measure of the next song are displayed on the screen, and the accompaniment function corresponding to the first measure is possible, and fast forward and backward navigation is possible, and when the first measure of the desired song is displayed, the stop key is pressed. By selecting the song automatically, the video panel allows the user to easily select the desired song. The present invention relates to a method for performing an automatic search function of a periodic embedded television.

In general, a television can 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 is provided for introducing a video and audio signal from an external device. 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 that is rapidly developed and marketed is a device for displaying lyrics along with song accompaniment by connecting to a TV monitor, and an LD image accompaniment system using a laser disc player and a 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 video and sound quality than any sound source, but since only 30 songs are contained on one laser disc, Juke Box can be used to service a large amount of songs. A disk changer such as

In addition, the CDG video accompaniment system can provide the same sound quality as a laser disc, but provides only a limited number of still picture information recorded in a sub-code channel of a compact disc, compared to a laser disc. In addition to the deterioration of the connection between the image and the music, 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 1500 songs. There is an advantage that the selection can be made faster, 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.

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 TV having a built-in image repeating period according to the present invention.

Referring to FIG. 3, it is determined whether the image accompaniment mode is selected (S301). If the video accompaniment mode is not selected, the television mode is performed (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, a general accompaniment function is performed (S304).

If the auto search function is set, items of genre are displayed on the screen (S305).

The selection number for each gen is input (S306). At this time, 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 selection number by gen is completed, the songs by the corresponding genres among the songs stored in the memory are automatically searched and the title of the first song corresponding to the selected gen is displayed on the screen (S307).

It is determined whether a cancel key is input (S308). If the user wants to cancel the current genre, if the user inputs a cancel key, the user returns to the item display step of genre (S305).

If the intake key is not input, it is determined whether the search mode is normal (S309).

In the general search mode, the title and the first measure are displayed from the first song selected by the display of the first song title for the selected genre (S307) and the accompaniment function corresponding to the first measure is performed (S310). .

If it is determined in the step S309 of determining whether the normal search mode is not the normal search mode, it is determined whether the high speed forward search mode (S311). If it is determined that the fast forward search mode is displayed, the title and the first measure are displayed at high speed from the next song in the fast forward state and the accompaniment function corresponding to the first measure is performed at high speed (S312).

If it is determined in step S311 whether the fast forward search mode is not the fast forward search mode, it is determined whether it is the fast backward search mode (S313). If it is determined that the fast reverse search mode is displayed, the title and the first measure are displayed at a high speed in the fast reverse state and the accompaniment function corresponding to the first measure is performed at high speed (S314).

If it is determined in the fast reverse search mode determination step (S313) that the fast reverse search mode is not, all the processing ends.

On the other hand, in the normal search mode to display the title and the first measure from the first song at the same time performing the accompaniment function corresponding to the first measure (S312), or to display the title and the first measure from the previous song at high speed in a fast backward state at high speed At the same time, after performing the accompaniment function corresponding to the first measure (S314), it is determined whether a stop key is input (S315).

If the stop key is input, it is determined that the user has found a desired song and performs an image accompaniment function on the corresponding song (S316). On the other hand, if it is determined in the stop key input determination step (S315) that the stop key is not input, it is determined whether the search function is completed (S317). If it is determined that the search function is not completed, the process returns to the stop key input determination step (S315) again, and when it is determined that the search function is completed, all the processing ends.

Here, while performing the accompaniment function corresponding to the first measure (S310, S312, S314) while displaying the title and the first measure of the song during the search, a method of displaying the next song immediately after the first song is displayed or For example, a method of searching for the next song after a predetermined time, for example, after 3 seconds has elapsed may be used. In addition, in the normal search mode and the fast forward and backward search mode, the intervals between the songs may be set differently. That is, in the general search mode, the interval between each tune may be set to 3 seconds, and in the fast forward and backward search mode, the interval between each tune may be set to 1 second.

For example, to describe in more detail as follows.

Determines whether 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.

When the auto search function is selected, genre-specific items are displayed on the screen. At this time, the item for each gen is displayed such that a title arbitrarily selected by the user is displayed together. That is, it is as (Table 1).

The user enters the number corresponding to the genre. For example, if the user wants to search by 'singer', the user inputs '1'. 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 status at this time is shown in (Table 2).

When the user inputs the corresponding number, all songs sung by the singer of the corresponding number are searched from the memory, and the title of the first song is displayed. For example, when the user selects '2' and inputs a key, the displayed state is shown in (Table 3).

If the user inputs a cancel key when the genre is not the desired genre, the display returns to the item display step per gen. If no cancel key is input, it is determined whether the search mode is normal. In the normal search mode, the title and first measure are displayed from the song displayed in (Table 2), and the accompaniment function corresponding to the first measure is performed.

When the display and accompaniment function of the first song of the first song is completed, the title and the first measure of the next song are displayed and the accompaniment function corresponding to the first measure is performed.

Repeat this process continuously.

Here, the display and accompaniment function for the next song may be started soon after the display and accompaniment function for the first song is completed, and the user may move to the next song at a predetermined time, for example, 3 seconds. You can also proceed. The selection for this can be arbitrarily determined by the user.

If it is determined that it is not the normal search mode, it is determined whether it is the fast forward search mode. When it is determined that the fast forward search mode is performed, the title and the first measure are displayed from the next song in the fast forward state and the accompaniment function corresponding to the first measure is performed.

When the fast display and accompaniment function of the first measure of the corresponding song is completed, the title and the first measure of the next song are displayed at high speed, and the accompaniment function corresponding to the first measure is performed at high speed.

Repeat this process continuously.

Here, the display and accompaniment function for the next song may be started immediately after the display and accompaniment functions for the corresponding song are completed, or the user may move to the next song at a predetermined time, for example, 3 seconds. In addition, it is possible to proceed to the next song with a time interval of, for example, one second shorter than the time interval in the normal search mode. The selection for this can be arbitrarily determined by the user.

If it is determined that the fast forward search mode is not, it is determined whether the fast forward search mode is present. If it is determined that the fast reverse search mode, in the fast reverse state, the title and the first measure are displayed from the previous song and the accompaniment function corresponding to the first measure is performed.

When the fast display and accompaniment function of the first measure of the corresponding song is completed, the title and the first measure of the previous song are displayed at high speed, and the accompaniment function performed on the first measure is performed at high speed.

Repeat this process continuously.

Here, the time interval between the display and the accompaniment function for the next song after the display and accompaniment function for the corresponding song is started is the same as in the aforementioned fast forward search mode.

When the display of the title, the first measure, and the accompaniment function corresponding to the first measure are completed, it is determined whether a stop key is input. Here, when the user finds a desired place during the search, the user inputs a stop key, and when the stop key is input, the user determines that the song is selected and performs an image accompaniment function for the song.

Here, if the stop key is not input, it is determined whether the search function is completed, and if the search function is not completed, the process returns to the step of determining whether the stop key is input again and repeatedly performed until the stop key is input, When the search function is completed, the user decides that there is no song to select and finishes all the proceedings.

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 according to genre is stored in the memory and the user selects the desired genre in the memory. Displays the title and first measure of the song corresponding to the selected genre among the stored songs, and performs the accompaniment function for the first measure.When the display and accompaniment function of one measure is completed, the title and the first measure of the next song are completed. Display on the screen and perform the accompaniment function corresponding to the first measure, enable fast forward and backward navigation, and when the first measure of the desired song is displayed, enter the stop key to automatically select the song. By adding a function, there is an advantage that a user can easily select a desired song.
