Referring to FIG. 3, a method of controlling a character display apparatus of a karaoke system according to the present invention is as follows.

First, when the power of the karaoke system is turned on, the music selection is searched for, and if the music selection is delayed, the music selection detection steps 100, 101, and 102 are output and displayed on a monitor. That is, if the power of the karaoke system is high, it searches for the selection of the selection until the set time has elapsed. If the selection is not completed, the corresponding character signal, that is, the OSD signal, is output to display the corresponding character on the monitor. Is being slowed down. '

After the user selects a desired song, a category is determined in an atmosphere corresponding to the selected song, and categories and playing steps 103, 104, and 105 are performed to play the selected song. In other words, if the selected song has a cheerful mood, if the selected song is sad mood, if the selected song is sad mood category, if the selected song is related to love, the love mood category, if the selected song has a farewell mood Because it is divided into categories, the corresponding category is determined, and the selected song is played.

Image signal search and OSD signal output step of searching for the point where the video signal corresponding to the category determined after performing the category determination and playing steps (103, 104, 105) and outputting the corresponding OSD signal and displaying it on the monitor until the search is completed. 106, 107, 108). That is, in order to display the video signal that matches the mood of the determined category on the monitor, find the point where the corresponding video signal is recorded on the tape, and output the corresponding text signal, that is, the OSD signal, until the completion is completed. For example, display a text such as "Now searching."

When the search is completed after performing the video signal search and the OSD signal output steps 106, 107, and 108, the video signal reproduction step 109 is performed to reproduce and output the corresponding video signal.

Performing the video signal reproduction step 109 performs the OSD signal output step (110, 111, 112, 113, 114) of the playing state to search the current playing state until the play of the selected song is completed, output the corresponding OSD signal and display on the monitor.

The OSD signal outputting step of the playing state may include outputting the corresponding OSD signal and displaying it on the monitor when the currently playing state is being played (110, 111) and the corresponding OSD if the selected song is currently playing. Outputting a signal and displaying the same on a monitor (112, 113), and if the syllable is set to the currently playing state, a corresponding OSD signal is output and displayed on the monitor. Can be.

In other words, if the currently playing state is playing, the character signal suitable for the category and the current situation, that is, the OSD signal, outputs the corresponding character on the monitor, for example, 'Now is playing,' or the character matching the category of the selected song. For example, try to display a text such as "clapping hands together" or "with a sad heart".

In addition, if the current playing state is considered, the character signal corresponding to the category and the current situation, that is, the OSD signal, outputs a character corresponding to the monitor, for example, 'Now considered,' or a character matching the category of the selected song. For example, display characters such as 'poetry related to love', 'poetry related to friendship', and 'cheer and clap.' Also, if the number of syllables that are currently playing is played, the corresponding character on the monitor, for example, 'holding hands' and 'clap' Try to display characters such as mate, mate, mate, or 'in a familiar mood'.

As described above, the present invention provides an AI display karaoke system that displays characters or numbers that match the user's mood on the monitor during performance and video signal search, thereby doubling the user's enjoyment in use.
