The present invention relates to a karaoke remote control device having an electronic table of contents function for transmitting a remote control signal for reserving the music to a karaoke device.

The karaoke apparatus accepts the request song by the music number, and manages the number in the queue of the performance reservation. Then, the music numbers in the queue are sequentially picked up to play karaoke music corresponding to the picked-up music numbers.

Input of music number is performed only using the karaoke remote control apparatus which is attached to a karaoke apparatus. Usually, to check the music number of a karaoke piece, use the karaoke table of contents placed in the karaoke room. As is well known, the karaoke table of contents classifies a large number of karaoke pieces according to their attributes (by song name, singer, genre, etc.), so that the karaoke pieces can be searched by index.

The karaoke remote control device includes a user control panel on which ten keys and a transmission key are arranged, a display unit for monitoring and displaying a music selection number input from the control panel, and a wireless I / F (interface) for transmitting the input music selection number to the karaoke main unit using an infrared signal. And the like, and are configured as follows.

That is, when a karaoke user inputs a music selection number from the ten key of the said operation part, the music selection number is temporarily hold | maintained in a register, and the displayed music selection number is monitor-displayed on a display part. Although the karaoke user can confirm a wrong input by this monitor display, when there exists an operation correct | amended by the said operation part at this stage, the acceptance process is performed.

When the karaoke user operates by pressing the transfer key of the operation unit in the step of inputting the selection number, the selection number stored in the register is converted into an infrared signal of a predetermined format and wirelessly transmitted (transmitted) to the karaoke main body apparatus. In this case, once the transfer operation is performed, the contents of the registers are initialized (cleared) and returned to the no input state. This is to avoid the problem that the same request song is duplicated and reserved when the transmission key is pressed twice by mistake.

As described above, in the conventional karaoke remote control device, by selecting (clearing) the music number input by the karaoke user for each transmission operation, it is possible to avoid the problem of duplicate reservation by pressing the transmission key twice. Sometimes when a person crosses in front of a remote control device or when some shield is interposed, transmission from a remote control device to a karaoke main body device may not be performed correctly. In such a case, a troublesome user has to enter the same selection number again from the beginning.                         

There is also a karaoke room recently replacing the conventional karaoke table of contents and karaoke remote control device with a karaoke remote control device having an electronic table of contents function. Karaoke remote control devices having an electronic table of contents function have been commercialized as computer application devices similar to notebook computers and palmtop personal computers, and a liquid crystal touch panel is often used as a user interface. Then, the contents of the karaoke table of contents are stored in an external storage device having built-in contents, and a music index database is constructed. The search keyword entered by the user is searched in the database, and the table of contents information and the music number of the corresponding karaoke music are presented and outputted. If the karaoke piece of music that the user wishes to play is finally designated, the performance reservation code including the piece number of the piece of music is transmitted to the nearest karaoke device as a remote control signal.

In the karaoke remote control device having such an electronic table of contents function, unlike a conventional remote control device, a piece of music is inputted to specify a piece of music, and a very troublesome operation is repeated, such as entering a keyword for searching for the same piece of music from the beginning. It must be done, which becomes more cumbersome as in the prior art.

=== Configuration of Karaoke Remote Control Unit ===

As a karaoke remote control device in the embodiment of the present invention, a karaoke remote control device having an electronic table of contents function is exemplified. 1 is a perspective view showing the appearance of a karaoke remote control device of the present embodiment. The apparatus main body 1 is generally a thick panel type, and the size is such that it can hold | maintain both hands lightly when the panel is lengthened horizontally. A liquid crystal display (LCD) 2 is disposed on the front face of the panel, and a touch panel 3 is stacked on the surface of the LCD 2.

On the upper surface of the panel case, there is an infrared ray transmitting portion 4 by a light emitting diode (LED), and on the lower surface, a terminal 6 for receiving power supply from an external power source when charging a secondary battery inside the main body, or an external The terminal 5 for the interface (IF) of the RS232C standard for data communication with a computer is provided. Moreover, these terminal groups are not normally seen from the outside by the blind cover.

2 shows the internal structure of the karaoke remote control device 1 by a functional block diagram. The configuration of the karaoke remote control device 1 of the present embodiment is basically the same as that of a computer such as a PC. In the flash memory 12 functioning as an external storage device, attribute information, such as a song name, artist name, and lyrics beginning of a song, is stored in correspondence with the song number with respect to the karaoke music that can be used in the karaoke device. It is built. In addition, the central control unit 11, which is a main control unit of the karaoke remote control device 1, communicates with an external computer such as a karaoke device through an RS232C standard communication interface (IF) 13, and attribute information about the new karaoke music. The music index database is updated in a timely manner by downloading and storing the data in the flash memory 12 and the like.

When the central control unit 11 receives the operation input information from the touch panel 3 through the operation control unit 15, the image data prepared in the internal ROM or the processing result according to the operation input information in this image data. The bitmap image image data reflecting this in the video RAM is controlled, and the LCD driver 14 is controlled to display and output the bitmap image on the LCD 2. As a result, the karaoke remote control device 1 provides a GUI environment to the user. Then, the central control unit 11 realizes the electronic contents table function by searching the music index database through a dialogue between the user and the GUI and displaying the search result.

The central control unit 11 generates a code including the music number and the performance reservation command when there is a user input that the music is reserved for the performance of the final karaoke music in accordance with the electronic table of contents function. The code is then sent to the LED driver 16. The LED driver 16 applies the modulated signal of this code to the LED 17, and transmits the wireless remote control signal for the performance reservation to the karaoke apparatus.

=== Home Screen ===

3 shows a schematic diagram of the initial screen 20 displayed when the electronic table of contents function of the karaoke remote control device 1 is activated. On the initial screen 20, menu buttons 21 to start various search modes (new report, life name, song name, viewpoint, duet genre) and various functions (history, remote control) mounted on the karaoke remote control device 1 are provided. 28) is arranged. FIG. 4 shows, by a flowchart, a function called up when each menu button arranged on the initial screen 20 is instructed.

In addition, various command button groups 29 for operating the karaoke apparatus are arranged on the right side of the region where the menu buttons 21 to 28 are arranged, and when any command button is instructed, the karaoke apparatus is in preparation for playing or A performance change command is issued to change the performance of the karaoke music being played.

When any of the menu buttons 21 to 28 is instructed in the display of the initial screen 20, a task screen for operating each search mode and function shown in Figs. 5A to 5H is displayed. The karaoke remote control device 1 displays the task screens (A) to (H) as introduction screens to each operation mode (search mode and function), and at the same time, the introduction screens (A) to (H) according to the user's operation input. The task screen is shifted hierarchically, and the remote control signal including the music number is sent in accordance with an operation input for the purpose of finally specifying the music to be reserved for the karaoke apparatus by the user and to reserve the music for performance.

And when the user notices that this signal is not transmitted to the karaoke apparatus for some reason when the performance reservation remote control signal is sent, even if the user does not work for music search again, the remote control signal may be Redial is possible. Hereinafter, the re-sending function of the remote control signal in the karaoke remote control device 1 of the present embodiment will be described according to the operation procedure of the music search function.

=== Music search function ===

A music retrieval function for retrieving a search word from a music index database and finally specifying a music desired by the user will be described. Here, the "music name search" mode is taken as an example.

First, when the menu button 23 of "music name" on the initial screen is instructed, the task screen of the music name search mode shown in Fig. 5C is displayed. Fig. 6 shows the flow of music search processing in the music name search mode. 7A to 7E show transition diagrams of the screen displayed on the LCD 2 during this process. When the menu button 23 in the music name search mode is selected and instructed by the user on the initial screen, the keyword input screen a including the character pallet is displayed (s51 to 53). The user instructs the characters in this character palette and inputs the title of the karaoke piece of music as the first character from the head character. The central control section queries the music search database for the character string from the head character each time one character is input. For example, "ま な つ の…" ", The music search database is searched using the keyword" ま "as a search word at the time when" ま "was input. If the number of tunes of the karaoke music corresponding to this point is larger than the prescribed number, the input characters and the number of tunes are displayed at predetermined positions 31 and 32 on the screen as shown on screen b (s54 to s58 → S53). When the character after "な" is input following "ま", the input character string is inquired into the music search database for every character input opportunity, and the number of the corresponding music is displayed (c).

Here, when the "search" button 33 in the screen in which the number of music is displayed with this character pallet is instruct | indicated, the appropriate attribute information regarding the retrieved music is displayed over a plurality of pages (s58-> s59). In other words, it becomes difficult to see the attribute information of a plurality of pieces of music in a limited display area. Therefore, a plurality of retrieved pieces of music are sorted for each predetermined number, and the attribute information of pieces of music of the prescribed number is displayed on one screen. In the present embodiment, a plurality of karaoke pieces found are collectively displayed for every eight pieces in the order of music number (d).

In this list screen, the total number of pages and the currently displayed page number are displayed at the predetermined position 34. When the user instructs the page turning button 35, the front and rear pages are displayed along the direction of turning the pages. Then, the attribute information of the other music pieces is displayed (s59 to s61). If the character input is to be continued and the character is searched again, the "return" button 36 in the list of attribute information is instructed to cause the character pallet to be displayed again (s62? S53).

If the display column of a certain piece of music is instructed while the user sequentially browses the list of searched music items over a plurality of pages, the karaoke remote control device displays and outputs detailed attribute information about the indicated piece of music (s63 → s64, e). . When the user sees the display screen e of this detailed attribute information and confirms that it is a musical piece intended for the purpose, the "transfer" button 38 arranged in the display screen of this detailed attribute information is instructed. In this way, the karaoke remote control device transmits a remote control signal for reserving the music (s72 → s73).

If a person crosses the front of the karaoke remote control device at this time, the remote control signal is not transmitted to the karaoke device correctly. Assuming such a case, the karaoke remote control device 1 realizes a user interface that can transmit the remote control signal sent earlier and minimize the possibility that the same piece of music is continuously reserved for performance. Specifically, the first remote control signal is prohibited from being transmitted more than once in a very short time, and the second transmission is allowed within a predetermined time after the prohibition time elapses. That is, after calmly confirming to the user whether the transmission of the first remote control signal is successful or not, the second transmission instruction is received.

As the internal processing of the karaoke remote control device 1, the central control unit 11 temporarily stores the code RAM corresponding to the remote control signal sent by the central control unit 11, and starts the timer based on the transmission. The elapsed time from the time point at which the first remote control signal is transmitted is monitored (s74), and the predetermined time is set as the re-reservation prohibition period, and the remote control signal is not transmitted even if the "send" button 38 is instructed within this prohibition period. This rebooking prohibition period is a period during which the user is prevented from being embarrassed to &quot; continuously push &quot; the &quot; transfer &quot;

If the "transfer" button 38 is instructed within this period, the predetermined time is set to be a reschedulable period after the prohibition period elapses, and the code in the RAM is transmitted again as a remote control signal. This re-reservable period is a period for the user to transmit the remote control signal of the performance reservation again after confirming the transmission error of the first remote control signal. In this embodiment, the rebooking prohibition period is set to a relatively short time (for example, 2 seconds), and the bookable period is set to a longer time (for example, 8 seconds). When the second remote control signal is sent, the central control unit 11 clears the code in the RAM and redisplays the task screen a of the song name search process (S75 → s76 → s78 → s51). In addition, even when the "transfer" button 38 is not instructed within the reschedulable period, the task screen a of the music name search process is displayed again (S75-> s76-> S77-> s51).

=== Other Embodiments ===                     

In the above embodiment, the rescheduling period is set only once, and if there is a user input of the performance reservation within this period, the screen is switched immediately to transfer to the subsequent processing. This configuration is not limited, for example, even if the second remote control signal is transmitted, the detailed screen of the attribute information may be displayed until the rebookable period of time has elapsed.

Alternatively, after the re-reservation prohibition period has elapsed, the user may also have a disturbance caused by a transmission error. Therefore, the third remote control signal may be allowed in the re-reservable period in consideration of the failure of the transmission of the second remote control signal.

After the first remote control signal is transmitted, the display of the "Send" button on the detailed information screen of the attribute information may be "retransmission", and the user interface may be presented to the user that the first remote control signal has been transmitted. . In addition, if it is the structure which transmits a 3rd or more remote control signal, the button may display the number of transmission of a remote control signal by "third" etc.

According to the karaoke remote control device of the present invention, when the remote control signal is not correctly transmitted to the karaoke device, the same remote control signal can be retransmitted, and the same piece of music can be prevented from being repeatedly reserved in the karaoke device.
