DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus in which one video is shared by a plurality of music pieces and the amount of stored video is reduced.

[0002]

2. Description of the Related Art A karaoke apparatus in which music data and video data are separated and one video is shared by a plurality of music, greatly reduces the capacity of a video storage medium such as a laser disk (LD). be able to. Such a music / video separation type karaoke apparatus reproduces or synthesizes music from music data and outputs it from a speaker, forms a lyrics image and displays it on a monitor, as well as a video such as an LD player. The supply unit is added, and the video control data included in the music data is sent from the main unit to the video supply unit, and the corresponding video data is taken into the main unit. The video data taken into the main body is superimposed on a monitor displaying a lyrics image and displayed as a background moving image.

[0003] There are many types of video control data used in the conventional music / video separation type karaoke apparatus, which designate the number of video data held by a video supply unit. For example, as shown in FIG. 2, when video 1, video 2, video 3... Are stored in a time-series manner on the optical disc, the video control data from the main unit specifies the chapter (section video) number n of the video ( n
= 1, 2, 3 ...). The video supply unit converts the number n into a track number and outputs video data. For example, number 2
Is specified, the time on the disk from time t1 to t2
Is always started from time t1 and output.

[0004]

However, since the playing time of a plurality of music pieces sharing the same video 2 varies, for example, if the playing time of the music piece is shorter than (t2−t1), the video 2 Is played back only halfway, and the main body ends capturing the video data at the end of the music, so that the video is interrupted in an incomplete state. In karaoke, the atmosphere of the ending is extremely important, and since the video is often made so that the ending is excited, ending the video by cutting it off halfway reduces the interest in karaoke.

One object of the present invention is to make the end of a section video always match the ending of the music regardless of the playing time of the music to be played, even in a karaoke apparatus in which one video is shared by a plurality of music. It is an object of the present invention to provide a karaoke device that can be obtained.

[0006]

According to the present invention, there is provided a karaoke apparatus comprising: a video supply unit having a plurality of types of video data; a music reproduction unit for reproducing music based on the music data; and a video control unit included in the music data. A video playback unit that sends data to the video supply unit and captures the corresponding video data, wherein the video control data is stored in the video playback unit so that the ending of the music to be played matches the ending of the video to be played back. It is characterized by specifying a start position.

In this case, in a case such as an optical disk player in which the video supply unit stores a plurality of types of video data together with time information, the video reproduction start position is time information. Further, the karaoke apparatus to which the present invention is applied may be not only a tone reproduction type but also a tone synthesis type.

[0008]

According to the video control data of the present invention, the video reproduction start position of the video supply unit is specified so that the ending of the music to be played and the video to be reproduced coincide with each other.
Even if the performance time of the music is shorter than the reproduction time of the video and the music is different for each music, the ending of the music to be played always matches the ending of the video to be reproduced. For this reason, it is possible to fully enjoy the karaoke atmosphere in which the music and the video are integrated while having a small video storage amount.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram showing one embodiment of the karaoke apparatus of the present invention. In FIG. 1, reference numeral 1 denotes a video supply unit that holds a plurality of types of video data, 2 denotes a music reproduction unit that reproduces or synthesizes musical sounds based on music data, and 3 denotes a video supply unit 1 that transmits video control data included in the music data. A video playback unit 4 for receiving the corresponding video data by sending it to a speaker 4 for outputting the reproduced music, and a monitor 5 for displaying the reproduced video. The tone reproduction unit 2 and the video reproduction unit 3 are included in the karaoke apparatus main body. The main body also has a function of generating a lyrics image from the lyrics data included in the music data, and the lyrics image is superimposed and displayed on the monitor 5.

The video control data of the present invention specifies the video playback start time of the video supply unit 1 so that the ending of the music to be played and the ending of the video to be played back coincide. That is, when the storage state of FIG. 2 is represented as shown in FIG. 3 for convenience of description, for example, even if the video 2 is played back, it includes not the start time t1 of the video but the end time t2 corresponding to the ending, A time t which is traced back by a performance time of the music (in this example, (t2-ts)).
The reproduction of the video 2 is started from s. That is, by starting the reproduction of the video 2 from the middle of the video, the ending of the music and the video are matched.

An example will be described. Now, assuming that t1 = 5'30 "t2 = 11'30" t3 = 16'30 ", the section length of the video position is 5 minutes and 30 seconds, the section length of the video 2 is 6 minutes, and the section length of the video 3 is 5 minutes. At this time, if a tune having a performance time of 3'20 "is to be played along with the video 2, the reproduction start time of the video is ts = 11'30"-3'20"=8'10". Just do it.

There are several methods for including the reproduction start time ts in the video control data. One is a method of calculating and writing a video reproduction start time ts in advance in a part of music data as shown in FIG. The reproduction start time ts is determined by the length of the performance data (performance time) and the type of the specified video. The determination principle is as described in FIG.

[0013] As shown in Fig. 5, the music data includes the length (performance time) of the performance data and the atmosphere of the music in advance (in the case of Fig. 5, the release date of the music, whether the music is for the elderly, etc.). , Or information for young people). In this case, the reproduction start time ts is calculated by the program for controlling the video reproduction unit 3 from the atmosphere and the performance time. The type of video, that is, whether video 1 or video 2 is selected depending on the atmosphere of the music, and the reproduction start time ts of the video
Is calculated based on the music playing time.

In the case of this method, even when the background video of certain music data is obtained from the video supply unit 1 having different contents, the video supply unit 1 uses the music atmosphere and performance time data attached to the music. The video playback can be started from the video playback time that matches the video playback time. That is, FIG.
As shown in the figure, the video supply unit 1 outputs video type data held by the video supply unit 1 to the video reproduction unit 3, that is, a table of start time, section time, or the like. Please refer to the contents of possession. By doing so, the program that controls the video reproduction unit 3 refers to this table and refers to the video supply unit 1.
Can read video data that matches the atmosphere of the music data from a position that matches the video data held by the music data. This is because even if the image data held by the image supply unit is updated or changed, if a table corresponding to the new contents is output each time the update or change is performed, a new image can be obtained. Video data that matches the atmosphere of the music data can be read from a position that matches the content.

The stored images are, for example, image 1 is enka (summer), image 2 is enka (winter), image 3 is kayo (town), image 4 is kayo (country), and so on. And share each with songs with a similar atmosphere.

[0016]

As described above, according to the present invention, even in a karaoke apparatus in which one video is shared by a plurality of music pieces, the ending of the video and the music piece is always performed irrespective of the playing time of the music piece to be played. It is possible to provide a karaoke apparatus that is able to fully enjoy the karaoke atmosphere in which music and video are integrated, while having the same amount of video storage and a small amount of video storage.
