A SELECTIVE RECORDING METHOD IN A SINGING ROOM SYSTEM}

1 is a simplified configuration diagram of a karaoke system according to the present invention,

2 is a block diagram showing a method of using a file stored by the karaoke system according to the present invention as a mobile phone ringtone,

3 is a flowchart illustrating a process of selectively storing a song according to an accompaniment of a user in a karaoke system according to the present invention.

The present invention provides a method and system for selectively recording only songs and accompaniment sounds of various noises generated in karaoke by the operation of the semi-period and sound wave decibels, and downloading them as cell phone ringtones using the selectively recorded digital sound sources. It is about.

As the number of karaoke users increases, there is an increasing demand for recording and storing or using songs sung in karaoke. Accordingly, karaoke operators also want to provide new services or make money by recording and recording songs sung by users. There has been an effort to.

Korean Patent Application No. 1995-0039757, filed by Samsung Electronics, has a recording function that can record the user's song and the music output from the karaoke device by attaching a tape recorder and a CD player to the body of the karaoke device respectively. Karaoke device is open to the public. This has the advantage of saving the realism by recording all the sound sources generated in the karaoke as it is in the analog method, but it is difficult to distinguish between the noise and the song, it is difficult to use in other digitized applications.

On the other hand, as the Internet environment is established in karaoke, instead of simply storing CDs and tapes recorded in karaoke, a scheme has been developed to use the recorded songs in various ways by storing them on a server and using the Internet communication network. For example, Korean Patent Application No. 2001-0031818 converts the recording data of a song sung by a user in a karaoke into a digital voice data file such as an MPEG file, and stores it in a database on the Internet. It also discloses how to provide it on the Internet. The method comprises the steps of: (A) outputting an analog audio signal of a song sung by the user from a karaoke device or a microphone attached to the karaoke device; (B) converting the output analog voice signal into a digital voice data file such as MP3; (C) the converted digital voice data file is transmitted through an internet network and stored in a database; And (D) providing the stored digital voice data file to the user via a website.

The application proposes a method of selectively recording only a time zone for singing during a time using karaoke by determining a recording time by sensing on / off of microphone power and estimating it as a singing time. However, the power of the microphone and the power of the semi-period are usually separated, and even when the song is not sung, the microphone is often turned on, and thus, there is a problem in that the accompaniment is actually performed and the time of the song is not accurately known.

In addition, in addition to the song that a user usually sings, a variety of sound sources such as anti-addressing, third-party voices, applause, and templars are combined to create various levels of noise. In such a system, the data input through the user's microphone is recorded, so the user's song and the half-address and the room noise provided through the amplifier are input together, so they cannot record only their own songs cleanly. Will be.

On the other hand, a digital sound source recorded as a ringtone for a mobile phone or other mobile communication means is used as a ringtone for a mobile phone or other mobile communication means. When the MP3 file is extracted to reduce the amount of data transmission, the use range of the recorded sound source is very limited. In fact, there has been a problem that cannot be used as a ringtone of a mobile phone.

Therefore, in using the existing karaoke system, there is a continuous demand for a method of accurately checking a user's singing part and recording clean semi-addresses and songs in the checked recording time zone. In addition, the recorded data can be recorded as easily as Microsoft's Windows Media Player, which is widely used as a music player, and can be uploaded by processing the recorded data into a music file of a suitable type for use in a mobile phone ringing. The demand for it continues.

In addition, the method of transmitting and using the analog or digital format file generated by the karaoke device through the Internet network as described above is a problem that needs to establish the Internet connection network connected to the device for generating the sound source, for example, each karaoke device This has a problem that the installation cost and communication cost increase in view of the fact that a large number of karaoke equipment is installed in one store.
