[Problems to be solved by the invention]
Mood footage is now one of the pleasures of karaoke. For this reason, making the mood video rich and rich will greatly enhance the commerciality of karaoke.
[0010]
By the way, the karaoke apparatus using the above-mentioned shared mood image has been generally used for a long time. The mood footage reflects the situation at the time of the shooting, and as time passes, the discrepancy with the current situation is gradually increasing. In order not to lose the freshness of the image, it is necessary to update the mood image to reflect the current situation.
[0011]
However, some songs sang in a certain era or featured a particular subject. In such songs, there are some that require attention to the content of the mood video. For example, a car sung by a specific vehicle type name may be mentioned. In such a song, it is meaningless to replace the specific car model even with the latest car model. Also, no matter how much the music of a skier at a ski resort is lyricized, the appearance of a snowboarder is meaningless, no matter how much the recent ski resort is reflected.
[0012]
Therefore, if the shared video scenes are uniformly updated, even the video scenes that require such attention will be updated, and the content of the karaoke music may be shifted. It is needless to say that each time a video scene is updated, it can be easily realized by rewriting the portion of the video editing script for each karaoke song that uses the updated video scene. However, as described above, the video editing script describes the music ID, the video switching point, the video effect, and the storage location of the video scene in association with each other. In order to rewrite this, it is necessary to make correspondence between each music piece while confirming the video switching point indicated by the elapsed time from the performance start time and the updated video scene. Furthermore, in the current situation of the karaoke market where new songs are provided one after another, it is inefficient to rewrite the video editing script of tens of thousands of karaoke songs one by one just to update the video scene. Not realistic.
[0013]
Therefore, the inventor of the present invention thought that it would be very convenient if the shared video scene could be renewed without rewriting the video editing script and excluding songs that did not require updating of the video scene.
[0014]
[Means for Solving the Problems]
In view of the above, an object of the present invention is to provide a video updating method that does not need to rewrite a video editing script and that takes into account music that does not require updating of video scenes.
The video updating method according to the present invention comprises a means for managing a video database storing a long-time video composed of a set of video scenes of a large number of sections, and for each karaoke song in which a permutation of a plurality of video scene identifiers is described. Means for managing a video editing script of a karaoke tune by playing the corresponding video scenes in order from a video database in accordance with the permutation of video scene identifiers described in the video editing script for the karaoke tune. In the karaoke video reproducing apparatus that outputs video, a replacement video scene for replacing an existing video scene is additionally registered in the video database, and information indicating a correspondence relationship between the identifier of the existing video scene and the identifier of the added video scene is stored. A replacement movie that is recorded in the replacement information table and indicates whether to use the replacement video scene for each karaoke song When a usage flag is additionally set and a certain karaoke music piece is played, it is recorded that a replacement video scene exists in the replacement information table for the video scene included in the video editing script for that music piece, and If the flag indicates that a replacement video scene is to be used, mood video output control is performed by replacing the existing video scene identifier in the video editing script with the replacement video scene identifier according to the recorded contents of the replacement information table. It is characterized by the following.
[0015]
Preferably, for a song that is additionally registered in the karaoke song database after the replacement video scene is additionally registered in the video database, the identifier of the replacement video scene can be described in the video editing script for the song.
[0016]
Desirably, the replacement information table also includes the replacement video scene registration time information, and the replacement video scene use / non-use is specified by the registration time information as the replacement video use flag.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
=== Overview ===
The karaoke video reproducing apparatus according to the present embodiment is a karaoke apparatus having a well-known configuration illustrated in FIG. The karaoke data for each song is composed of music performance data, which is the origin of accompaniment music represented by MIDI data or ADPCM data, using song IDs as keys, and lyrics subtitle data for displaying lyrics subtitles synchronized with the accompaniment music. And a data group in which the above-described video editing script and the like are associated with each other. The karaoke video reproducing apparatus constructs and manages a video database using a CD-ROM or the like as a storage resource. During a karaoke performance, a specified video scene is extracted from the video database according to the video editing script, and the mood video is edited and displayed on the display 8 as in the prior art.
[0018]
The updating method according to the present embodiment is based on a correspondence table for replacing an existing video scene before updating (replacement) with a replacement video scene when a karaoke company puts a replacement video scene of mood video into a video database and registers it. The replacement information table is also registered and managed. A karaoke data of each music piece is additionally set with a replacement video use flag indicating whether or not to use the replacement video scene instead of the existing video scene when outputting the mood video of each karaoke music piece. At the time of a karaoke performance of a certain music piece, it is checked whether or not the replacement video scene is used for this music piece by referring to the replacement video use flag, and the replacement information table is referred to for the video scene included in the video editing script for this music piece. To see if there is a replacement video scene. If the replacement video scene for the video scene used in the music is registered and the replacement video scene is set to be used in the music, the replacement video scene described in the video editing script (existing video scene) The video scene is replaced with a replacement video scene in accordance with the correspondence shown in the replacement information table, and the video output is performed.
[0019]
In this way, for a song that does not need to use the replacement video scene, the replacement video use flag in the replacement information table is simply set to “no use”, and the existing video scene before updating (replacement) is replaced with the video. Is output. Other songs can be renewed as replacement video scenes. There is no need to rewrite the video editing script for any of the songs, and the management of replacement video scenes can be simplified.
Hereinafter, the updating method will be described in detail.
[0020]
=== Register replacement video scene ===
FIG. 2 illustrates a logical configuration of the replacement information table. As shown in this figure, the replacement information table 21 associates the storage position (identifier 22) of the existing video scene with the storage position of the replacement video scene. The storage position is generally represented by a segment ID indicating a start position and an end position of the video program. In this embodiment, the section ID is expressed by a disk storage location including a changer ID of a CD-ROM changer and a disk number in the changer, and a temporal position (minute / second / frame) within the disk. . Each storage position is specified by the section ID of the start position of each video scene. The karaoke company distributes the CD-ROM including the replacement video scene, creates a replacement information table corresponding to the replacement video scene, and distributes and manages the replacement information table to the karaoke video playback device.
[0021]
At this time, a replacement video use flag is additionally set in a field which can be appropriately written, such as a header portion of karaoke data for each music piece. FIG. 3 illustrates a logical configuration of the karaoke data including the replacement video use flag. As the replacement video use flag 31, a separate flag 31 is set for each replacement video scene registration time. When a replacement video scene is used for a certain song, a “1” bit is set in the corresponding flag 31. In other words, the version of the replacement video scene is identified by the registration time in the video database, and it is possible to designate to use the replacement video of an appropriate version for each music. This makes it easy to flexibly update the video.
[0022]
=== Video output processing during karaoke performance ===
FIG. 4 shows a processing flow chart of the mood video output processing accompanying the karaoke performance. When the karaoke video playback device requests a karaoke music piece, the karaoke data corresponding to the music piece ID is taken out, the performance is prepared, and the video editing script 32 is read out. Then, first, the replacement video use flag 31 is confirmed. Whether the replacement video use flag 31 indicates to use the replacement video scene (step 401 in FIG. 4), and when it is used, indicates when to use the registered replacement video scene (designated version). ) Is confirmed (step 402). Further, referring to the replacement information table 21, the identifier 22 of the video scene described in the video editing script 32 is compared with the identifier 22 of the existing video scene. It is confirmed whether or not it is included as a video scene (step 403). If it is included, the replacement video scene identifier 22 corresponding to the existing video scene is extracted by referring to the replacement video scene column of the designated version (registration time) of the replacement information table 21. Then, the identifier of the video scene in the video editing script 32 is replaced with the identifier 22 of the replacement video scene (step 404). The same processing (steps 403 to 404) is performed on all of the video scenes included in the video editing script 4, and the replaced video editing script is temporarily stored.
[0023]
When the performance of the music starts, measurement of the elapsed time of the video elapsed time is started. Then, in accordance with the replaced video editing script, the time is compared with the time corresponding to the video switching point, and an appropriate CD-ROM is set in the driving device 3 according to the identifier of the video scene described in each video switching point. Then, the video data is output starting from the described time position, and the video data is output to the display 8 with the specified video effect (step 405).
[0024]
In addition, it is also possible to adopt a system in which the video output script 32 is read while reading the video editing script 32 and the video output process is performed while performing the necessary replacement.
[0025]
=== Other Embodiments ===
For a song that has been registered and used as a karaoke song before the replacement video scene is input, the process of replacing the existing video editing script 32 based on the replacement information table 21 is performed as described above. That is, only the identifier (storage position) 22 of the existing video scene is described in the video editing script 32 of the music.
[0026]
On the other hand, for a song registered as a karaoke song after the replacement video scene is inserted, it does not prevent the identifier 22 of the replacement video scene from being directly used in the video editing script 32 for the song. In this way, it is possible to prevent the replacement information table 21 from growing in an infinite chain.
[0027]
In the above-described embodiment, an example in which the video database is constructed by using the optical disc reproducing device 3 as a storage resource has been described. In that case, the storage position of the video scene can be represented using a folder name, a file name, a relative address in the file, and the like on the hard disk device 2. By using the hard disk device 2 as a storage resource, additional registration of a replacement video scene can be performed from the karaoke host device via a communication line.
[0028]
