Description

  The present invention relates to a karaoke system including a karaoke performance device for playing a music piece desired by a user and displaying lyric video data corresponding to the performance music piece on a display device.

  In recent years, karaoke has become a popular pastime regardless of age or gender, and is widely installed in karaoke boxes and snack shops, and is spreading nationwide. On the other hand, general karaoke performance devices installed in each store can store background data such as performance data of more than tens of thousands of songs and a large number of artist videos from the beginning with the recent increase in storage capacity. As a result, a stand-alone device has a sufficient usage condition without adding data to the communication karaoke device, so that the karaoke performance device is stolen. Therefore, at present, a karaoke performance device capable of preventing theft or deterring theft is desired.

  Therefore, conventionally, a karaoke performance device having a theft prevention function has been conceived. For example, Patent Document 1 discloses a technique for making an online karaoke performance device unusable even if it is stolen. Specifically, a karaoke performance device is connected to a host computer via a communication network, and a predetermined log data is periodically transmitted to the host computer. When the log data is not correctly transmitted to the host computer, a predetermined quantity The performance device itself cannot be used after the measurement. That is, in view of the line disconnection due to theft and the temporary line disconnection due to maintenance, etc., it can be used only for a predetermined short period of time, and thereafter it is disabled to prevent theft.

Japanese Patent No. 3196166

  However, in the antitheft method disclosed in Patent Document 1, it is essential that the karaoke performance device is connected to the host computer and the communication network. Therefore, in an area where a communication network is not yet established. At present, karaoke is becoming common in other countries, and there are countries where networking using ADSL, ISDN, optical communication technology, etc. is delayed, and this method cannot be applied.

  The present invention has been made in view of the above problems, that is, even if the karaoke performance device is of a stand-alone specification, such as use in an area where a communication network is not yet established, theft prevention or theft deterrence can be prevented. The issue is to provide a karaoke system that can be used.

  In view of the above problems, the present inventors comprise a karaoke performance device for playing a music piece desired by a user and displaying a lyric image corresponding to the performance music piece on the display device. An identification code is assigned, and the identification code of a predetermined display device is registered in advance in the karaoke performance device, and the display device is authenticated by checking whether the assigned identification code matches the registered identification code. Providing a system for controlling whether or not to display the lyric video data of the performance music according to the authentication result, more preferably, in the case of a mismatch, predetermined measurement is started, It has been found that the above-mentioned problem can be solved by providing a system for controlling the display of the lyric video data up to the set measurement value and not displaying the lyric video data, and the karaoke system of the present invention has been conceived.

That is, the karaoke system according to claim 1 of the present invention is a karaoke system including a karaoke performance device for playing a song desired by a user and displaying a lyric image corresponding to the performance song on a predetermined display device. In
(A) The karaoke performance device
A data transmission / reception unit for exchanging data with the display device;
A video output unit for sending lyrics video data of an arbitrary performance song to a display device;
An identification code registration unit for registering an identification code of a predetermined display device in advance;
An identification code transfer unit for transferring the registration identification code to the display device;
(A) The display device has no mobility,
A data transmission / reception unit for exchanging data with a karaoke performance device;
A display control unit for receiving and displaying lyrics video data from a karaoke performance device;
An identification code storage unit for storing an identification code for identifying the display device;
An identification code authenticating unit for inquiring and authenticating a match / mismatch between the transferred registration identification code and the identification code of the display device;
In accordance with the authentication result, the display control unit controls to display the received lyrics video data in the case of a match, and controls not to display in the case of a mismatch.
It is characterized by that.

  Further, in the karaoke system according to claim 2 of the present invention, in the karaoke system according to claim 1, when the authentication result does not match, the time measurement unit starts time measurement of natural time or operation time, The display control unit controls to display the lyric video data up to a preset measurement value and not to display it thereafter.

  According to the karaoke system of the first aspect of the present invention, authentication is performed by inquiring whether the identification code of the display device matches the identification code registered in advance, and the identification code matches. The lyric video data of the performed musical piece is displayed and can be used normally, but if it does not match, it is not displayed, so the lyric video cannot be seen and cannot be used normally. As a result, if theft is intended, the display device must be stolen together with the karaoke performance device. In addition, the recent increase in the size of the display device makes it difficult to steal, and the karaoke performance device has a stand-alone specification. Even so, it has the effect of preventing theft or deterring theft.

  According to the karaoke system of claim 2 of the present invention, when the authentication result does not match, the time measurement of the natural time or the operation time is started, and the lyric video data is displayed up to the preset measurement value. Then, since the display is controlled so as not to be displayed, a certain amount of time lag can be set not to connection with the theft karaoke performance device but to the non-display control from the connection of the alternative karaoke performance device in the case of regular maintenance or failure. Therefore, there is an effect that normal use is not hindered for a certain period.

  Furthermore, according to the karaoke system according to claim 3 of the present invention, when the authentication results do not match, the number-of-performances measurement is started by the number-of-times counting unit, and the lyric video data up to a preset measurement value Since the display is controlled so as not to be displayed thereafter, the same effect as that of the invention of claim 2 is obtained.
