Hereinafter, the karaoke remote control device of the present invention will be described in detail with an optimal example.

The internal configuration of the karaoke remote control device of the present invention is shown in the functional block diagram of FIG.
First, in a flash memory (FM) functioning as an external storage, attribute information such as a song name, an artist name, and a lyric singing portion of an available performance song is stored in association with a song number, and a song index is stored. A database (not shown) is constructed, and the central control means (3) which is the main control unit of the karaoke remote control device (1) is a communication control means (2) for controlling communication via a wireless line or a wired line. The music index database is updated in a timely manner by downloading attribute information and the like about the new performance music and storing it in the flash memory (FM).

  When the central control means (3) receives input information from the operation panel (UI) controlled by the operation control means (6), the central control means (3) responds to the image data and input information prepared in the internal ROM. The image data reflecting the processed result is developed as a bitmap on the video RAM, and the LCD driver (CDD) is controlled to display and output the bitmap image on the LCD (LC). As a result, the karaoke remote control device provides a GUI environment to the user, and the central control means (3) searches the music index database through dialogue with the user and outputs the search result as an electronic table of contents. .

  The central control means (3) includes the corresponding music number if there is an input to reserve the performance of the music in the state where the performance music finally selected by the user is presented from the electronic table of contents. A reserved music code is generated and confirmed, and the code is transferred to the LED driver (EDD). The LED driver (EDD) gives a modulation signal of this code to the LED (LE), and causes the karaoke performance device to transmit an infrared signal for performance reservation.

  Further, the central control means (3) executes processing related to the electronic table of contents function and the transmission of the reserved music code, while managing the history of the music reserved for performance. In the flash memory (FM), a history of performance music reserved for performance is stored for a predetermined number of songs from the latest reserved music, and each time the reserved music code is transmitted, the music number is used as a recent performance reservation history. In addition to storing, the oldest music number in the history is deleted.

Here, the features of the karaoke remote control device of the present invention will be described in more detail with reference to FIGS.
First, in the karaoke remote control device (1) shown in FIG. 3, a predetermined ID such as a serial number or an IP address of the karaoke performance device (P) to be linked is registered in the central control means (3) to control communication. As described above, together with the performance device ID registration / recognition unit (4) for confirming whether the ID of the karaoke performance device communicated through the means (2) is the ID of the registered karaoke performance device , A counter which is a measuring unit (5) for adding 1 for each transmission of the reserved music code including the music number to the performance apparatus (P) is attached.

  Next, in the karaoke remote control device (1) shown in FIG. 4, the central control means (3) measures the usage time of the karaoke remote control device main body together with the same performance device ID registration / recognition unit (4) as in the above embodiment. The timer which is a measurement part (5) to be attached is attached. Note that the measured value of the timer cannot be unconditionally reset to the initial value regardless of ON / OFF of the remote control power source or the state of charge.

Any measuring unit in FIG. 3 and FIG. 4 for (5), the playing device ID registration and recognition section (4), sometimes ID karaoke performance device (P) was confirmed to have been registered, to no number of measurements The measurement value, which is the measurement time, is initialized, but after the number of times and the measurement time have reached a predetermined set value, the central control means (3) determines the predetermined value including the stop of the reserved music code transmission function. The control process is prohibited. The prohibition of the control processing is performed by denying access to software data, changing a program, or disconnecting or switching a hardware internal line.

Next, a preferred system flow of the karaoke performance apparatus of the present invention will be described using the flowcharts shown in FIGS.
As shown in FIG. 5, when the karaoke remote control device is activated and starts to be used, first, the user inputs a reservation for a desired music piece (step S1). Next, when the input music code is confirmed, the measuring unit of the central control means confirms the number of times of measurement at the time of confirmation, and when it reaches a predetermined set value (for example, 100 times), erases the LCD and karaoke The remote control device is automatically terminated. On the other hand, if the set value has not been reached, the confirmed music code is transmitted to the karaoke performance device (step S2, step S3, step S4).

When the confirmed music code is transmitted, even if the communication line for confirming the ID of the karaoke performance device is not normally connected, 1 is added to the count of the counter (steps S5 and S7). Further, even if the communication line is normally connected, if the ID of the karaoke performance device is not registered, 1 is added to the number of times the counter is measured (steps S6 and S7). When it is confirmed that the communication line is normally connected and the ID of the karaoke performance device is registered, the counter count is reset to an initial value (for example, 0) for the first time (step S8). The use is repeated (step S9).
The ID of the karaoke performance device is confirmed every time the performance music code is confirmed as in this embodiment, for example, if the remote control device itself has a wireless LAN function without using a cradle, the performance music code is transmitted. This is performed at a predetermined timing, such as every time, every predetermined time interval, or every time when the cradle is used, every time the cradle is mounted.

  Next, as shown in FIG. 6, when the use is started, the user first makes a reservation input of a desired music piece (step S1). Next, when the input music code is confirmed, the measuring unit of the central control means checks the measured usage time at the time of confirmation, and erases the LCD if a predetermined set value (for example, 100 hours) is reached. To automatically terminate the karaoke remote control device. On the other hand, if the set value has not been reached, the confirmed music code is transmitted to the karaoke performance device (step S2, step S3, step S4). The “use time” in the present invention is not limited to the use time of the user in a strict sense. For example, the time when the remote control is in the ON state and the secondary battery of the remote control is charged. It may be a certain time or an elapsed time from the initial setting before use.

When the confirmed music code is transmitted, if the communication line for confirming that the ID of the karaoke performance device is registered is not normally connected, the time measurement of the timer is continued (steps S5 and S7). Furthermore, even if the communication line is normally connected, if the ID of the karaoke performance device is not registered, the timer time measurement is continued (step S6, step S7). Then, when it is confirmed that the communication line is normally connected and the ID of the karaoke performance device is registered, the timer measurement time is reset to the initial value (for example, 0 hour) for the first time (step S8). The use is repeated (step S9).

  As described above in detail, in the karaoke remote control device of the present invention, even if it is stolen, for example, at the time of registration of confirmed music data or the cradle of the cradle using a wired / wireless line via a wireless LAN or a cradle. By checking the ID of the currently supported karaoke performance device at the time of wearing or at a desired timing such as a predetermined time interval, a measuring unit ( After the measured value by the counter or timer reaches a predetermined set value, the use cannot be continued, and as a result, the karaoke remote control device is prevented from being stolen. Furthermore, it can be used normally until the measurement value of the measuring unit reaches a predetermined set value, so if you want to use it temporarily for an unlinked karaoke performance device, or the linked karaoke performance device is broken. If you want to perform quick maintenance, you can bring a karaoke performance device that is not linked and temporarily replace it.

  The present invention can be variously modified without departing from the basic concept, and it goes without saying that the right extends to the modified one.
