DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a DVD (DIG)
The present invention relates to a karaoke apparatus that reproduces karaoke songs from ITAL VERSATILE DISC).

[0002]

2. Description of the Related Art In a DVD used for reproducing a karaoke song, a video and lyrics are recorded together with the accompaniment (sound) of the karaoke song. In addition to output, video and lyrics are output from the display. The lyrics are displayed in captions on the display, so that the singer knows where to sing, knows where to sing the lyrics, such as (a) adding a border (= shaded) to the character at the singing point, (B) The lyric part that has been sung and the lyric part that has not been sung are displayed in different colors.

[0003]

In the conventional karaoke apparatus, when singing starts, (a) the first character of the lyrics suddenly becomes bordered, or (b) the color of the lyrics suddenly changes color. only, unfamiliar of the singer, where for the first time any good to sing in advance from, do not know well, is causing the confusion.

[0004] It is an object of the present invention to provide a karaoke apparatus which overcomes the above-mentioned problems.

[0005]

A karaoke apparatus according to the present invention.
(15) has the following (a) to (c). (A) a karaoke song reproducing means for reproducing a karaoke song based on the karaoke song data; and (b) a singing start detecting means for detecting a singing start time of the karaoke song based on the karaoke song data before starting to sing. (C) display means for displaying a karaoke tune based on the singing start time detected by the singing start detecting means (25) and starting the reproduction of the karaoke tune a predetermined time before the start of singing

[0006] The singing start time is not limited to the perfect singing start time, but it is needless to say that it means a substantial singing start time. The reproduction by the karaoke music reproduction means includes not only the reproduction of all the accompaniment (audio), video, and subtitles (sub-pictures) of the karaoke music, but also the reproduction of only the accompaniment of the karaoke music without video and subtitles. Even if there is no video and no subtitles and only accompaniment, or if there is no video and only audio output of accompaniment and visual display of lyrics,
The singer may want to know the beginning of the singing, and in such a case, it is meaningful to inform the singer a predetermined time before the singing by an appropriate display. The karaoke music data is read out from an optical disk (10) such as a DVD, and also input to a karaoke device (10) at home or the like via a public telephone line such as ISDN or a cable of a cable television. The display before the singing by the display means for a predetermined time includes not only a visual display but also a voice display and a vibration display (a vibrator is mounted on a microphone of a singer or a stage on which a singer stands). In addition, the display includes not only one display before the first predetermined time, but also a plurality of displays such as before the first predetermined time, before the second predetermined time, and so on.
For example, a voice, an image, or both can be performed for a countdown in which the singing start is counted as 0. Further, not only instantaneous display but also continuous display is included.

[0007] In this way, the karaoke singer can clearly understand in advance that it is a predetermined time before the singing starts, and can make a thorough preparation, and even an unskilled singer can start singing smoothly. Become so.

According to the karaoke apparatus (15) of the present invention, the karaoke song data is displayed on the display together with the accompaniment data, the lyrics of the karaoke song and the lyrics present location indicating the current location of the lyrics to be sung at each time. And subtitle data to be displayed as subtitles. The singing start detecting means (25) detects the first appearance time of the lyrics current location display from the caption data as the singing start time.

In the lyrics displayed on the display as captions, the current location of the lyrics is displayed so that the singer can easily find the location of the lyrics sung at each time. For this reason, the caption data includes the data relating to the current position of the lyrics, and the first appearance time of the display of the current position of the lyrics in the caption can be detected from the subtitle data to detect the singing start time.

[0010] According to the karaoke apparatus (15) of the present invention, the current lyrics location is indicated by the outline of the lyrics text.

According to the karaoke apparatus (10) of the present invention, the lyrics present location is indicated by the color of the sung lyrics section and the non-sung lyrics section.

According to the karaoke apparatus (10) of the present invention, the subtitle data assigns each pixel to at least three of the background, color 1 and color 2, and displays the lyrics and the current location of the lyrics sung at each time on the display. To display. The singing start detecting means (25) sequentially includes at least one pixel (11c) of the background, at least one pixel (11b) of the color 2, and a color different from the color 2 in the arrangement direction of the subtitle characters. The display appearance time at which at least one pixel (11a) of 1 is continuous is detected from the caption data as the singing start time.

The arrangement direction of the subtitle characters is a horizontal direction when the lyrics are written horizontally, and is a vertical direction when the lyrics are written vertically. "At least one pixel of color 2 (11b),
And at least one pixel (11a) of color 1 "and" at least one "are used for a character having a thick outline, for example, by using two or more consecutive pixels (11a) of color 1 The outline may be displayed, and when the lyrics current location is indicated by the outline of the character, the outline is determined by using two or more consecutive pixels (11) instead of one pixel (11). This is because the edging width may be appropriately increased.

The display screen has a large number of pixels (11).
Subtitles on the display, each pixel (1
By controlling the color of 1), the lyrics of the karaoke song and the lyrics current location display such as bordering and color coding are displayed.
Therefore, at the current position of the lyrics, at least one pixel of the background, at least one pixel of the color 2 (11b), and at least one pixel of the color 1 different from the color 2 in the order of the subtitle characters Since the pixel (11a) is continuous, the singing start time can be found from the appearance time of such display.

According to the karaoke apparatus (15) of the present invention, the caption data includes a command for changing the color of the pixel (11) at a predetermined position of the caption, and the singing start detecting means (25) executes the command. As a result, the time at which the pixel color change first occurs for the pixel (11) at a predetermined position is detected from the caption data as the singing start time.

When the singing starts, the current position of the lyrics appears on the subtitles on the display. To display the lyrics current location display, an instruction to change the color of pixel (11) may be used. Therefore, the time at which the pixel color change first occurs according to the instruction can be found as the singing start time.

According to the karaoke apparatus (15) of the present invention, the karaoke music data includes the model vocal data for reproducing the model vocals. The singing start detecting means (25) detects the time when the audio amplitude level of the sample vocal first becomes equal to or more than a predetermined value as the singing start time from the sample vocal data.

The sample vocal starts when the singing start time comes, and the audio amplitude level becomes equal to or higher than a predetermined value. Therefore, it is possible to search for the time when the audio amplitude level of the model vocal becomes equal to or more than the predetermined value from the model vocal data for the model vocal reproduction, and detect it as the singing start time.

According to the karaoke apparatus (15) of the present invention, the karaoke music data is arranged in a unified manner in the reproduction progress direction. The singing start detecting means (25) detects the singing start time in the karaoke song data in the karaoke song data at a speed faster than the speed of the reproduction by the karaoke song reproducing device in the direction of the progress of the karaoke song data, and performs the scanning by the karaoke song reproducing device. Performed in parallel with playback.

The search speed of the karaoke song data in the reproduction progress direction by the singing start detection means (25) is faster than the reproduction progress speed of the karaoke music reproduction means. Even at the same time, the singing start time can be searched before the reproduction of the singing start of the karaoke song starts. Thus, the karaoke song reproducing unit can reproduce the karaoke song, and the singing start detecting unit (25) can detect the singing start time and the display unit can display the singing start time before the singing start without any trouble.

[0021] The karaoke apparatus (15) of the present invention further comprises:
Has the following: Reading means for reading karaoke song data from the optical disc (10) (16) Singing start detecting means (25) for detecting a singing start time based on the karaoke song data
Karaoke song reproducing means for starting to play a karaoke song based on the karaoke song data after the singing start detecting means (25) detects the singing start time

This reading means (16) can be applied whether reading is performed at 1 × speed or at 2 × speed or higher. Also, after the user specifies a karaoke song,
In addition to reading out the karaoke song data of the specified karaoke song and detecting the singing start time, the karaoke singing start time of the karaoke song recorded in the pixel data is checked in advance before being specified by the user. It is also possible to make a note in the memory and read the singing start time from the non-volatile memory when the user specifies a karaoke song.

The singing start detecting means (25) searches for the singing start time in the karaoke song data and detects the singing start time prior to the start of the karaoke song reproduction by the karaoke song reproducing means. As soon as the singing start time is detected, the reproduction of the karaoke tune by the karaoke tune reproducing means is started. When a predetermined time before the singing starts, the display means displays a predetermined time before the singing starts. In the karaoke apparatus (15), since the karaoke song is reproduced after the singing start time is detected, the search speed of the singing start time by the singing start detecting means (25) in the karaoke song data is not sufficiently fast. Even
In other words, even if the playback speed of the karaoke song is lower than the playback speed of the karaoke song, the karaoke song can be displayed a predetermined time before the start of the singing.

FIG. 6 is a block diagram of the karaoke apparatus 15 for DVD. The DVD mechanical unit 16 reads out the karaoke song data from the DVD 10 at a double speed or higher for the karaoke song specified by the user. The changeover switch 17 alternately switches the output of the DVD mechanical unit 16 to the track buffer 20 or the track buffer 30 alternately at a predetermined cycle (for example, every two seconds). As a result, the same karaoke song data can be alternately input to the track buffer 20 and the track buffer 30 for a predetermined reproduction time from the beginning of the karaoke song. The track buffer 20 centrally stores data input as a pack from the DVD mechanism unit 16. The demultiplexer 21 extracts only subtitle picture packs from the input from the track buffer 20. The subtitle picture buffer 22 combines subtitle picture packs input from the demultiplexer 21 to generate subtitle picture data. The subtitle picture decoder 23 decodes the subtitle picture data, and the singing start time detecting section 24 outputs the subtitle picture data from the subtitle picture decoder 23 and (display control).
Based on the sequence, the singing start time (Ts in terms of reproduction time from the beginning of the karaoke song) is detected. The singing start time predetermined time before calculating section 25 calculates a time (Ta in terms of playback time from the beginning of the karaoke song) that is a predetermined time before the singing start time. On the other hand, similarly to the track buffer 20, the track buffer 30 stores data input as a pack from the DVD mechanical unit 16 in a unified manner. The demultiplexer 31 separates the input from the track buffer 30 into subtitle picture packs, video packs, and audio packs, and outputs them to the subtitle picture buffer 32, video buffer 33, and audio buffer 34, respectively. The subtitle picture buffer 32, video buffer 33, and audio buffer 34 combine subtitle picture packs, video packs, and audio packs, respectively, to generate subtitle picture data, video data, and audio data. The subtitle picture decoder 35, the video decoder 36, and the audio decoder 37 decode subtitle picture data, video data, and audio data. The decoding of video and audio data is based on MPEG. The timer 40 receives, for example, a karaoke song reproduction start signal from a clock (not shown) related to the video debuffer 33 or the audio buffer 34, and the elapsed time T from the karaoke song reproduction start time (= the time from the reproduction start time). Playback time). The comparison unit 41 compares the reproduction time T from the timer 40 with Ta calculated by the calculation unit 25 before the singing start time a predetermined time,
When T ≧ Ta, the subtitle preview unit 42 is instructed to output a preview subtitle image a predetermined time before singing from the subtitle preview unit 42 to the video synthesizing unit 43. The video synthesizing unit 43 synthesizes the video of the subtitle picture decoder 35, the video decoder 36, and the subtitle preview unit 42, and video-outputs the synthesized video to a display (not shown). The D / A converter 45 D / A converts the digital audio signal from the audio decoder 37,
The audio synthesizing section 46 mixes an analog audio signal from the D / A converter 45 with an audio signal input from the microphone 47 as a singer's voice and outputs an audio signal generated to a speaker (not shown).

In S51, the first unread portion of the subtitle picture data of the karaoke tune to be reproduced this time by the user's designation is read. In S52, it is determined whether or not the current position of the lyrics is to be displayed in the subtitle picture data for the unit, and the determination is YE.
If S, the process proceeds to S53, and if NO, the process proceeds to S55. In the reproduction of the karaoke song of the DVD karaoke device 15,
The video and lyrics are output as video along with the audio output of the accompaniment, and the lyrics are displayed as subtitles on the video on the display, and the current lyrics location as the current lyrics location to be sung is shown in FIGS. As described, the borders and the sung parts that have been sung and the non-sung parts that have not been sung are indicated by color coding. In the case where the current location of the lyrics is indicated by a border, the singing start time can be detected from the appearance of the border in the subtitle. When the current location of the lyrics is indicated by the color of the sung part and the non-sung part, the color of the subtitle is determined. Singing start time can be detected from the appearance of. Specifically, as shown in the pixel column 12 in FIGS. 2 to 5, the singing starts after the singing starts, so that the appearance of the pixel column 12 can be considered as the singing start time. Also, in the previous frame (corresponding to one screen of the display and consisting of two fields, top and bottom), the pixel 11 which is responsible for the background around the character is shown in FIG.
4 and FIG. 3, and as shown in FIG. 4 and FIG.
If the pixel 11 which has been a non-sung part in the current frame carries another color 2 in this frame, the present frame display time can be considered as the singing start time. The appearance of the pixel row 12 and the color change of the pixel 11 can be easily detected from the presence of a color code setting command, a color change command, and the like in the pixel data and sequence of the caption picture data (FIG. 1). In S53, the execution time ts (= singing start time) of the lyrics current location display found in S52 is detected. The execution time of the color code setting command or the color change command of the pixel data in the sequence of the caption picture data can be detected from the data of the execution time written before the first command in each sequence, and the execution time of the execution time can be detected. The data is expressed in relative time conversion from the start time written in the packet of the pack in which the unit is mounted, and thus the singing start time Ts is calculated by the reproduction time conversion Ts from the beginning of the karaoke song. Can be detected. In S54, a value Ta (= Ts-Tc) smaller than Ts by a predetermined value Tc is calculated. Since Ts is the playback time from the song start time to the singing start time, Ta is
This corresponds to the conversion of the karaoke song to the reproduction time at the time before the singing start time Tc. In S55, it is determined whether or not the reading in S51 has been completed for all the units of the subtitle picture data. If the determination is YES, that is, if the singing has not been completed, the process proceeds to S56.
The process proceeds to step S51, where it is determined that no singing has started, and the routine ends. If the determination is NO, the process returns to step S51.

FIG. 8 is a flowchart of a display routine a predetermined time before the start of singing. In S60, the elapsed time T from the beginning of the karaoke song is measured. In S61, the elapsed time T is compared with Ta calculated in S54. If T ≧ Ta, the process proceeds to S62, and if T <Ta, the process returns to S60.
In S62, it is displayed that the song has been sung to the subtitle of the subtitle picture and that it is a predetermined time before.
