Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internet karaoke device, and more particularly to displaying lyrics in a karaoke device including an internet karaoke device using a WWW browser.

[0002]

2. Description of the Related Art Conventionally, in an Internet karaoke apparatus, a dedicated karaoke software which can be connected to the Internet is activated on a PC (personal computer),
I was downloading music from the internet and playing it.

To view information on the Internet, WWW
A tool called a (World Wide Web) browser is required, and a so-called home page can be browsed by designating an address corresponding to the location of information called URL (Uniform Resource Locator).

A WWW browser is an HTML (Hyper Text
Markup Language) can be used to read data such as predetermined images, music, and videos from a server on the Internet for display and reproduction.

The Internet karaoke software is also a WWW browser specialized in karaoke style such as display and function. The WWW browser incorporates dedicated software for producing images and sounds, and is a dedicated application that runs on a PC.

In the conventional internet karaoke apparatus,
As shown in JP-A-10-63276 and JP-A-9-190189, the sound of the music is delivered together with the background image suitable for the music, and the lyrics are displayed together with the background image. Then, the character data in different colors was also sent.

FIG. 8 is a schematic view showing a display of a conventional Internet karaoke apparatus. The client terminal 20 is connected to the Internet, first downloads the dedicated software of the Internet karaoke device, and when the program is started, the PC as the client terminal downloads the music data on the Internet, and downloads the music data to the Internet karaoke. It is read into the dedicated software 21 of the device. The play button 22 is pressed to start playing the music. The lyrics 24 are displayed in different colors on the background image 23 of the music.

[0008]

However, in the past, the lyrics were displayed by incorporating them in the background image, or the color-changed image of the lyrics was sent as image data.
When the lyrics display size is increased, the data capacity increases, and it took time for the client terminal 20 connected to the Internet using a low-speed modem or the like to read and reproduce the image data of the music.

Since the client terminal 20 connected to the Internet at low speed takes a long time to download in order to read a large amount of image data, the lyrics display area is limited and the display is small.

In the prior art, the lyrics are superimposed on the background image,
Since the image processing is performed to change the color of the lyrics, a CPU having a high calculation processing speed is required.

In view of the above point, the present invention utilizes the MIDI data to change the color of the lyrics, and in order to change the color of the lyrics, it is possible to shorten the time until the color data is read and the color is reproduced. The purpose is to provide a method.

[0012]

The present invention is characterized in that MIDI data in which a separator (mark: example #) for changing the color of the lyrics is inserted in the lyrics data is used.
In addition, MIDI is Musical Instruments Digita here.
l An abbreviation of Interface.

The present invention provides an internet karaoke device for displaying lyrics in different colors using the MIDI data described above. Further, the present invention provides an internet karaoke device, which is characterized in that an image display area and a lyrics display area are separately provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an embodiment of an Internet karaoke apparatus, which shows the structure of the Internet karaoke apparatus. In Figure 1, PC (personal computer)
The client terminal 1 is connected to the WWW server 2 via the Internet 11 by a LAN or a modem.

The WWW browser 3 of the client terminal 1 has a built-in MIDI sequencer, which is a MIDI sound source, and uses MIDI in HTML and Java Script language.
DI data can be controlled and reproduced. The MIDI sequencer for reproducing the MIDI data 4 may be a software sound source or a hardware sound source. The WWW server 2 has, in the MIDI data 4, lyrics data 4a in which a separator (for example, # as a mark) for changing the color of the lyrics is inserted in the lyrics. WWW
The browser 3 is separately provided with an image display section 6 which is an image display area and a lyrics display section 9 which is a lyrics display area on the screen. A processing device (not shown) for controlling the image display unit 6, the lyrics display unit 9, the reproduction button 7, and the speaker 8 is provided in the client terminal 1. This processing device includes a color change display processing means.

When the home page address of the Internet karaoke device is input to the WWW browser 3 (the input section is not shown), the WWW browser 3 sends the MIDI data 4 and the image data 5 which are the data of the predetermined music from the WWW server 2. read out. The WWW browser 3 displays an image based on the read image data 5 on the image display unit 6, and when the reproduction button 7 is pressed, the music of the MIDI data 4 is reproduced from the speaker 8 while the lyrics data included in the MIDI data 4 is reproduced. 4a is displayed on the lyrics display section 9. At this time, due to the action of the separator inserted in the lyrics data 4a,
As will be described later, the lyrics are changed in color and displayed on the lyrics display section 9.

WWW is a WW on the Internet.
W protocol (HTTP: Hyper Text Transfer Protocol)
ol) is a network of client terminals and servers, and the WWW server 2 and client terminals 1 are
Information is exchanged using HTTP. In response to a request from the client terminal 1, the WWW server 2 sends text data, MIDI data, image data, etc. to the client terminal 1, and at the client terminal 1, the WWW browser 3 displays text data, image data, etc.
DI data is reproduced. In the embodiment of the present invention, the client terminal 1 reads and reproduces the data in the WWW server 2. However, these MIDI data are stored in a storage means such as a local disk or a memory of the client terminal 1 of the karaoke apparatus. Even if they are read out, they can be displayed and reproduced similarly.

The WWW browser 3 displays an image based on the image data 5 on the image display unit 6 and is in a state where Internet karaoke can be reproduced. The image data 5 may be a single still image, a plurality of still images, or a moving image. Further, even if the image is not displayed, the function of karaoke can be achieved only by reproducing the MIDI data and changing the color of the lyrics.

Next, the MIDI data used in the present invention will be described in detail. In general, MIDI has SMF (Standard MIDI Format) standards, which are standard MIDI, and MIDI data is reproduced in accordance with these standards. Each piece of SMF data is called an event and is divided into three events represented by a MIDI event, a SysEx (system exclusive) event, and a meta event.

The MIDI event is performance data, and the system exclusive event is an event for controlling a MIDI sequencer or the like. The meta event stores additional information other than the MIDI event, and stores information such as time signature, tempo, author information, and lyrics.

FIG. 2 is a diagram showing details of the meta event. In the meta event, a sequence number indicating the flow of the music and a text for describing an arbitrary text character string,
Copyright display for displaying copyright holder information, sequence / track name for describing sequence / track name, instrument name describing instrument name corresponding to each channel,
Lyrics for describing lyrics in text strings, markers for describing point names in the sequence as text strings, cue points for giving instructions to videos, etc.
M for giving channel attributes to events that do not have attributes such as meta events and SysEx events
IDI channel prefix, end of track indicating end of track, set tempo indicating tempo per beat by tempo, track chunk S to start
MPTE (Society of Motion Pictures and Television
Engineers) SMPTE offset indicating time etc. is included. SMPTE is a control signal that becomes a reference when synchronizing a video or tape recorder. There are time signatures, key signatures that represent sharp flats, and sequencer-specific meta-events used for sequencer-specific data. These formats TYPE are defined by hexadecimal numbers.

In the embodiment of the present invention, in the lyrics item of the meta event, a mark # for indicating the color change position of the lyrics is put in the lyrics as a separator function.

FIG. 3 is a diagram showing a sequence of MIDI data. At what measure, what kind of beat and what kind of note is to be reproduced, etc. are described. For example, bar: 1
0, time signature: 0, note: 2, event: meta event, type: 05, the lyrics "There was one banana" are described. The notes describe what kind of sound you can make using the instrument.

When the play button 7 of the WWW browser 3 is pressed, the MIDI sequence of FIG. 3 is executed one by one from the upper stage to the lower stage to reproduce the musical sound.

FIG. 4 is a flow chart for displaying the lyrics while changing the color. FIG. 4 shows an embodiment of the present invention.
This will be described with reference to the flowchart of. In S1, WWW
When the reproduction button 7 of the browser 3 is pressed, the reproduction of the MIDI data 4 previously read is started. Then M in Figure 3
The IDI sequence is executed one by one from the upper stage to the lower stage to reproduce musical tones (S2).

In S3, it is determined whether the MIDI data has been played to the end. It ends when it is played to the end. Next, in S4, if the MIDI data is not played to the end in S3, the event data in the MIDI data is monitored, and if the meta event has lyrics data,
The lyrics data read in is displayed on the lyrics display section 9 of the WWW browser 3 (S5).

At this time, the character string displayed on the lyrics display section 9 is "There was one banana". And S
In step 6, # included in the lyrics data is read out, and the character string on the left side of # in FIG. 5 is displayed in red and the character string on the right side of # is displayed in black.

Next, in S7, when there is blank data in the meta event, the lyrics displayed in the lyrics display section 9 is cleared (S8), and the reproduction is repeated from S2. In S7,
If there is no blank data in the meta event, the lyrics displayed on the lyrics display section 9 are not cleared, and the reproduction is repeated from S2.

Since the MIDI data contains the lyrics and the data indicating the color change of the lyrics as the music progresses, it is displayed as if the color changes in synchronization with the musical tone.

FIG. 5 is a schematic diagram showing a change in color change of lyrics. During the repeated reproduction of S2 to S7, S
In FIG. 21, the lyrics on the left side of the separator # are displayed in red and the lyrics on the right side of the separator # are displayed in black. In other words, "ba" is red and "there was one Nana" is black. Other colors may be used.

When the next lyrics are read, "Bana" is displayed in red and "I had one na" is displayed in black, as shown in S22. In this way, as shown in S22 to S25, the number of characters of the character color (red) on the left side is increased and the number of characters of the character color (black color) on the right side is reduced with the separator # as the center, so that it is apparently black. The characters are displayed as if they were painted in red. It is displayed in different colors.

When all the letters "There was one banana" turn red, the following lyrics, for example, "Under the Blue South Sky" are read, and the color of the letters changes in sequence.
Repeated until the end of the lyrics. The character string for determining the color change does not have to be the separator #, and may be any other character string or symbol as long as it is a character string that can be clearly identified from the lyrics (eg, $, &,%, etc.). good. You can change the color of characters and symbols that are not included in the lyrics.

Lyrics data 4a shown in the lyrics display section 9
May change the black lyrics to red, or change blue to orange to display,
Other colors may be used. Since the WWW browser 3 discriminates only the character string for identifying the color change, the color arrangement of the characters can be decided on the WWW browser 3 side.

FIG. 6 is an explanatory diagram showing an actual display.
Lyrics are displayed in the lyrics display section 9 immediately below the image display section 6. During the MIDI sequence, if there is a meta event lyrics, the lyrics are read into the WWW browser 3 and the lyrics are displayed on the lyrics display section 9.

The lyrics may be on the image, left and right, or may be only the lyrics.

In the lyrics display section 9, "banana (red)"
There was one (black) ”(Fig. 6 (1)), but there was one banana (red), there was (black)” (Fig. 6)
(2)). The same applies to FIGS. 6 (3) and 6 (4).

When the lyrics are large, the screen inevitably becomes large. Therefore, when the lyrics are displayed together with the image data, the data capacity also becomes large.

In the embodiment of the present invention, since the lyrics data of the text included in the MIDI data is used for display on the WWW browser 3 without sending the image data including the lyrics data, the size of the display character is changed. The size can be determined on the WWW browser 3 side.

Since the lyrics are displayed in the font of the WWW browser 3, the size of the character can be changed by the setting of the WWW browser 3. Since the lyrics are changed in color without sending color information, the lyrics can be changed in color with a small amount of data.

When trying to display lyrics of the same size on both a client terminal that is connected to the Internet at a low speed and a client terminal that is connected to the Internet at a high speed, the client terminal that is connected to the Internet at a low speed cannot display the lyrics. Inevitably, it takes time to display.

By using the lyrics data of the text having a small capacity that can be transferred without difficulty even by the client terminal connected at a low speed, the lyrics color change display can be performed by WWW.
You can make it larger or smaller by specifying the font of the browser.

FIG. 7 is a diagram showing another embodiment of the present invention.
It is a schematic diagram showing a display when applied to a mobile phone.
The client terminal connected to the Internet used for Internet karaoke may be a wired personal computer or a wireless mobile phone. While reproducing the MIDI data as in the present invention, the lyrics text and the color-changed character string of the MIDI data are sent, and the image display unit 3
Internet karaoke that displays an image on the screen 3 and displays the lyrics in different colors on the lyrics display section 34, like the WWW browser 32 used for the mobile phone 31,
Suitable for cases where the display is small and the speed of the line connecting to the Internet is slow.

[0043]

Since the present invention uses MIDI data in which a separator (mark: for example, #) for indicating the color change position of the lyrics of the music is inserted in the lyrics data, the separator is used to display the data on the client terminal side. The lyrics can be changed in color with a WWW browser. As a result, it is possible to provide an internet karaoke device and an internet karaoke method in which the time until the lyrics data is read and the lyrics are displayed in different colors is shortened.

According to the present invention, since the lyrics are displayed in different colors by using the above-mentioned MIDI data, the position where the lyrics are changed in color can be determined, and the WWW browser on the client side can be used without sending the character color data. It can be displayed in the character color of the specified lyrics.

In the present invention, since the image display area and the lyrics display area are separately provided and the MIDI data is used, the lyrics are only the text data in the MIDI data, and the WWW browser side changes along with the lyrics color change. It can be displayed in the font size specified by the font. Since the lyrics data and the color change data are text data and have a small data capacity, even a user connected to the Internet at a low speed can display the lyrics in a large display area.
