BACKGROUND OF THE INVENTION
The present invention relates to a karaoke apparatus that reproduces information service data (hereinafter referred to as ICM (Interactive Commercial Message) data) such as information and CMs at the time of startup of the apparatus or between songs that are not played.
[0002]
[Prior art]
Some karaoke devices installed in karaoke boxes, etc. are designed to reproduce CMs and information when a customer visits the store, between songs where karaoke songs are not played, or when the karaoke device is closed. .
[0003]
[Problems to be solved by the invention]
By the way, if the CM and the information are not reproduced accurately in consideration of the reproduction scene, the effect is halved. For example, greetings that do not match the time of day and time zone, and information and CMs that do not match the region and seasons are not effective and have the disadvantage of giving a bad impression to the customer.
[0004]
Therefore, it is necessary to prepare ICM data according to various scenes such as timing, time zone, season (time), and region. In this way, all types of ICM data are prepared and each terminal device (karaoke device) Responding to the download is very burdensome for the distribution center. Also, in the karaoke apparatus, downloading all ICM data suitable for each scene and storing it internally requires a lot of memory and requires a lot of memory capacity, and ICM suitable for the scene to be played back. There is a drawback that ICM cannot be played back when data is not downloaded.
[0005]
An object of the present invention is to provide a karaoke apparatus capable of reproducing an optimal ICM in any scene by using ICM data having various pages and selecting a page according to the scene.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a karaoke apparatus according to an embodiment of the present invention. This karaoke apparatus is a so-called sound source karaoke apparatus that generates a karaoke performance sound by driving a sound source and an audio data processing unit. The operation of the sound source and the sound data processing unit is controlled based on the music data for karaoke performance. In addition, lyrics and background video are displayed on the monitor 29 in synchronization with the generation of the karaoke performance sound. About 10,000 pieces of music data are stored in the hard disk 27. The hard disk 27 stores ICM data in addition to music data. The ICM data is data for reproducing greetings and various information / CMs at various timings such as when the karaoke apparatus is started up, between songs (when there is no request for karaoke music), or when the apparatus is terminated. The greetings, information, CMs, etc. (hereinafter referred to as ICM) to be reproduced differ depending on the scene such as the region, timing, date and time. For example, at the time of starting up the apparatus, if it is daytime, "Hello", if it is at night to display and announce the greeting of "Good evening", it is when the device is the end to the display of "cheers for good work". At the same time, greetings such as “Cold days continue” are displayed and announced in the northern regions such as Hokkaido, and greetings such as “Spring is approaching” are displayed and announced in the southern regions. The ICM also displays a background image in parallel with the display / announcement, but it is possible to switch between a snowy mountain image and a sea image depending on the region.
[0008]
The CPU 20 that controls the operation of the entire karaoke apparatus includes a ROM 21, a RAM 22, a hard disk (HDD) 27, a communication control unit 26, a commander receiving unit 23, an operation unit 24, a display unit 25, a MIDI interface 28, and a sound source 29 via a bus. , A voice data processing unit 30, a DSP 31, a character pattern development unit 36, an LD changer 37, and a display control unit 38 are connected.
[0009]
The ROM 21 stores a system program, a karaoke performance program, an ICM playback program, a loader, and character pattern data. The system program is a program for controlling the basic operation of this apparatus. The karaoke performance program is a program that drives the sound source 29, the audio data processing unit 30, the DSP 31 and the like based on the music data, generates karaoke performance sound, and controls the display of lyrics and the reproduction of background video. The ICM reproduction program is a program that reads ICM data and reproduces the ICM. The ICM reproduction program will be described in detail in the description of the flowcharts in FIGS. The loader is a program for downloading music data and ICM data from the distribution center. The character pattern data is data for expanding lyrics, song names, information contents, and the like given as code information into character patterns. This character pattern data is used when the character pattern development unit 36 displays lyrics based on the lyrics data or when displaying ICM character data based on the ICM data. In the RAM 22, a music data storage area 22 a for storing music data read from the hard disk 27 and an ICM data storage area 22 b for storing ICM data read from the hard disk 27 are set.
[0010]
The communication control unit 26 is a controller for communicating with a distribution center via a communication line and downloading music data and ICM data. The communication control unit 26 has a built-in DMA circuit, and can directly download downloaded music data and ICM data to the hard disk 27 without using the CPU 20. In the hard disk 27, a music data file 27a storing about 10,000 music data and an ICM data file 27b storing a plurality of ICM data are set.
[0011]
The commander receiving unit 23 receives the infrared signal sent from the commander 41 and restores the data. The commander 41 includes various key switches such as a music number registration key and a numeric keypad. When the user operates these key switches, the commander 41 outputs an infrared code signal corresponding to the operated key switch. The commander receiving unit 23 receives this infrared code signal and transmits it to the CPU 20. The operation unit 24 is provided on the front panel of the karaoke device, and includes a mode selection switch and a numeric keypad similar to those of the commander 41. The display unit 25 is also provided on the front panel of the karaoke apparatus, like the operation unit 24, and includes an LED matrix display that displays the number of the currently played song, the number of reserved songs, and the like.
[0012]
The sound source 29 forms a musical tone signal based on the musical tone data included in the music data. The audio data processing unit 30 reproduces an audio signal such as a back chorus based on the audio data included in the music data. The tone signal formed by the sound source 29 and the sound signal reproduced by the sound data processing unit 30 are input to the DSP 31. The DSP 31 imparts effects such as reverb and echo to these musical sound signals and audio signals. The type and degree of the effect provided by the DSP 31 is controlled based on the DSP control data included in the music data. The musical sound signal and sound signal to which the effect is applied are converted to an analog signal (karaoke performance sound) by the D / A converter 33 and then output to the amplifier 33. A singing voice signal is also input from the microphone 34 to the amplifier. The amplifier 33 mixes and amplifies the karaoke performance sound and the singing voice signal to drive the speaker 35. The audio data processing unit 30 reproduces the announcement audio data included in the ICM data when the ICM reproduction program is operating. The announcement is a sentence as shown in FIG. 4 by combining pieces of audio data as shown in FIG.
[0013]
Further, the character pattern development unit 36 develops the character pattern of the character code data of the lyrics track of the music data during the karaoke performance, and develops the character code data of the character display track of the ICM data into the character pattern during the ICM reproduction. The LD changer 37 reproduces a predetermined background video (moving image) during karaoke performance and ICM reproduction. The character pattern developed by the character pattern development unit 36 and the background image reproduced by the LD changer are combined by the display control unit 38 and displayed on the monitor 39.
[0014]
FIG. 2 is a diagram showing an example of music data. FIG. 2A shows the overall composition of music data, and FIG. 2B shows the structure of a melody track in a musical tone track as an example of a track. The music data consists of a header, a musical sound track, a lyrics track, a voice control track, and a DSP control track. The header is a portion in which various data relating to the music data is written, and includes data such as a music title, a genre, a release date, and a performance time (length) of the music.
[0015]
The musical sound track, lyrics track, voice control track, and DSP control track are all described in the MIDI format as shown in FIG. The MIDI format includes a plurality of event data and duration data Δt indicating a time interval between each event data. The sequence program counts Δt at a predetermined tempo clock, and when Δt is counted up, reads the event data that follows it and outputs it to a predetermined processing unit.
[0016]
The musical sound track includes a melody track and a rhythm track as well as various parts. The event data of the musical sound track includes musical sound generation (note on event) and musical sound muting (note off event) data, etc., and each event data includes event type (note on, note off, tone change, etc.), note number (sound) High) and velocity.
[0017]
The lyrics track is a track that stores sequence data for displaying lyrics on the monitor 39. This sequence data is not musical sound data, but this track is also described by a system exclusive message in the MIDI data format in order to make the implementation uniform and facilitate the work process. The audio control track is a sequence track for designating the generation timing and reproduction pitch of audio data stored in the audio data section. The voice data section stores voices such as back chorus and harmony singing that are difficult to synthesize with the sound source 29. In the DSP control track, DSP control data for controlling the operation of the DSP 31 is written together with duration data.
[0018]
FIG. 3 is a diagram showing the structure of ICM data. FIG. 4A shows the overall configuration of ICM data. FIG. 5B is a diagram showing an example of a page selection table included in the header of ICM data data. FIG. 4C is a diagram showing an example of a character display track and a voice control track included in the ICM data. FIG. 4D is a diagram showing an example of audio data included in the ICM data. FIG. 4 is a diagram showing an example of a display screen in which the data of each page of the character display track is developed by the character pattern development unit 36. As described above, greetings corresponding to various scenes (page selection data), CMs of karaoke boxes, and the like are written on each page of the ICM data.
[0019]
The ICM data includes a header, a character display track, an audio control track, and an audio data file. In addition, since the music data of karaoke is played as BGM during ICM playback, the ICM data does not include a track for generating musical sounds. The character display track and the audio control track are described in the MIDI format in the same way as each track of the music data in FIG. 2, and is composed of a combination of duration data Δt and event data as shown in FIG. The event data of the character display track includes data such as a display character code, the number of points (size), a display position, and a display color. The event data of the voice control data is composed of a voice data number. The audio data number is a number for identifying a plurality of audio data stored in the audio data file (see FIG. 4D). Each piece of audio data is ADPCM data that represents audio having substantially the same content as the screen display of FIG.
[0020]
Here, both the character display track and the audio control track are divided into a plurality of pages, and the ICM reproduction program can selectively read only a part of the specified pages among the plurality of pages. As shown in Fig. 4, the data contents (display contents, announcement contents) on each page correspond to specific areas, specific times, and specific time zones, and are specified by combining them appropriately. An ICM can be configured corresponding to the region and time zone.
[0021]
The page selection table is a table for determining which page of the ICM data is to be reproduced based on page selection data such as timing, region, date, and time zone. In addition, a page is determined and a BGM song and a BGV scene are designated.
[0022]
In the example shown in the figure, the area is divided into “Hokkaido”, “Honshu-Kyushu”, and “Amami / Okinawa” at each of the three timings of start-up, between songs, and at the end. Divided from April 11th to May 1st, and from May 2nd to May 31st until April 10th, and from 12:00 to 17:00, 17:00 to 20:00, and It is divided from 20:00 to 24:00. A page number to be reproduced is specified for each condition. One page or a plurality of pages may be reproduced. When a plurality of pages are designated, these pages are reproduced continuously in the designated order. The BGM is designated by the song number of the song data. BGM playback is performed in parallel with the reading of the character display track of ICM data (display of characters) and the reading of the voice control track (playback of announcement), but only the reading of the musical sound track (generation of musical sound) is performed, and the lyrics No display or back chorus playback is performed. Also, the BGV is specified by the LD chapter number or scene type. Thus, by selecting BGV and BGM separately from the page, even the same contents can be reproduced in different atmospheres depending on the region.
[0023]
5 and 6 are flowcharts showing the ICM playback program. FIG. 5A shows the activation processing operation. This operation is executed when the karaoke apparatus is started up or between songs without request. When the ICM reproduction operation starts, first, predetermined ICM data is read out to the RAM 22 (s1). Then, the page selection data of timing, region, date, and time zone is checked (s2). Thereafter, the process proceeds to each reproduction operation (FIGS. 6B, 6C, 7A, 7B). These playback operations are all processed in parallel.
[0024]
FIG. 5B is a flowchart showing the character display operation. First, the page selected by referring to the page selection table is determined (s5). Then, it jumps to the display page (s6). After that, the display sequence operation is executed (s7). In the display sequence operation, the character display track is read in order from the head. When the duration data is read out, the data is counted up and then the next data is read out. When the event data (character display data) is read out, the character pattern development unit 36 reads it. Is output to The character pattern development unit 36 configures a screen as shown in FIG. 4 based on the received character display data. This operation is terminated when the display of all pages selected in the page selection table is completed or when the customer performs some operation (s8, s9).
[0025]
FIG. 3C is a flowchart showing the announcement operation. First, the page selected by referring to the page selection table is determined (s11). Then, it jumps to the selected page (s12). After that, an announcement reproduction sequence operation is executed (s13). The playback sequence operation reads the audio control track in order from the beginning. When reading the duration data, it counts it up, then reads the next data, and when reading the event data (audio data number), it is specified by this audio data number. The voice data is output to the voice data processing unit 30. By reproducing the audio data, an announcement substantially similar to the wording displayed on the screen of FIG. 4 is reproduced. This operation is finished when the announcement of all the pages selected in the page selection table is finished or when the customer performs some operation (s14, s15).
[0026]
FIG. 6A shows a BGV playback operation. First, the playback scene specified by the page selection data is determined with reference to the page selection table (s20). The scene change number is instructed to the LD changer 37 (s21) and the reproduction start is instructed (s22). The LD changer 37 starts playback of the scene designated in response to this instruction. While the ICM is being played back, the playback of the BGV is continued, and when the customer performs some operation or the playback ends (s23), an instruction to stop playback is output to the LD changer 37 (s24). Thereby, the LD changer 37 stops the reproduction of the BGV.
[0027]
FIG. 6B shows a BGM playback operation. First, the song selection number designated by the page selection data is determined by referring to the page selection table (s30). After reading the music data of the music number (header, musical sound track, DSP control track only) (s31), the performance sequence process is started (s32). The performance sequence processing is an operation of only a sound generation operation by the sound source 29 in a normal karaoke performance operation. When the customer performs some operation or the reproduction is finished during the performance (s33), all the musical sounds are muted (s34). End the operation.
[0028]
The contents of the ICM are not limited to the examples shown in the above embodiment. Also, a performance track for playing BGM may be included in the ICM data, and this track may also be divided into pages.
[0029]
【The invention's effect】
As described above, according to the present invention, the ICM data is composed of a plurality of pages, and only the necessary pages are selected and reproduced according to the scene, so that all the scenes can be handled with one ICM data. Thus, both the distribution center and the karaoke apparatus do not need to store and communicate a large amount of ICM data, and there is an advantage that an optimal ICM can be reproduced at any scene.
