[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an audiovisual entertainment system, and more particularly, to a technique for intermittently playing a feature-length story image together with a karaoke performance.
[0002]
BACKGROUND OF THE INVENTION
Karaoke and video watching are typical examples of entertainment that is common to many people. Karaoke is a representative of entertainment that can be enjoyed together by a large number of people, whereas watching a video is in most cases an entertainment that can be enjoyed by a small group in each household.
[0003]
In recent years, in particular, video technology has been remarkably developed, and large-scale movies that can be enjoyed just by watching are being produced one after another, and each time it is talked about in the public. Because the number is many and the cycle is short, it seems that the show has ended shortly before going to the cinema, you want to watch it slowly at home when you like than watching the cinema, but not until you go to the cinema More and more people are watching video at home because they want to watch it.
[0004]
However, in today's world, where many children gather in one place and enjoy different mobile games in general, personal behavior is increasing in various scenes of society, and the number of people is the same. Entertainment such as karaoke is a precious thing.
[0005]
Karaoke, on the other hand, is primarily intended to be fun to sing, so you can enjoy it if your turn is around, but while listening to other people's songs, the music is played at a loud volume one after another. You can't afford to chat with other people on the scene, and you can be bored with extra time. At this time, if we borrow a karaoke display and show a clear movie with a story that enjoys the image, we will naturally want to watch the continuation and provide new fun to those who do not sing. Thought.
[0006]
The present invention has been made based on the above-described viewpoints, and an object of the present invention is to provide a video and audio entertainment system capable of intermittently reproducing a feature-length story video together with a karaoke performance.

BEST MODE FOR CARRYING OUT THE INVENTION
=== Configuration example of audiovisual entertainment system ===
FIG. 1 shows a hardware-based configuration example of a video and audio entertainment system to which the present invention is applied. The audiovisual entertainment system is a computer application device equivalent to a personal computer. The central processing unit 1 is a computer main body including a CPU, a RAM, and a ROM. The central processing unit 1 includes a hard disk device 2, a CD-ROM reproducing device 3, and a DVD-ROM reproducing device 4 as large-capacity external storage. A communication control device 5 for communicating with a karaoke host device via an ISDN line, a user interface device 6 for exchanging an input from a user and a response to the user, and music performance data mainly composed of MIDI data Music generating device 7 for generating an audio signal of karaoke accompaniment music based on the sound, karaoke accompaniment music or an audio signal amplifying an audio signal from a microphone and producing sound from a speaker, and a display using a CRT, LCD or PDP 9 and a video processing device 10 for processing video data to be displayed on the display 9. To have. A large number of CD-ROMs are removably mounted on the CD-ROM reproducing device 3 and are provided with a plurality of disk drives for selectively reproducing these disks by a changer.
[0011]
=== Example of database configuration ===
The video and audio entertainment system of this embodiment has a karaoke database and a video database, and the central processing unit 1 creates and manages a ledger for these databases in the hard disk device 2.
[0012]
The karaoke database is constructed using the hard disk device 2, the CD-ROM playback device 3, and the DVD-ROM playback device 4 as storage resources, and karaoke data for a large number of songs including music performance data and lyrics data is assigned a song ID. It is centrally managed as a key.
[0013]
The video database is constructed using the CD-ROM playback device 3 and the DVD-ROM playback device 4 as storage resources, and includes long-length story video data composed of moving pictures in MPEG format or the like that have a long-lasting storyline. Have been. A plurality of programs are prepared as feature story video data. For example, it can be specified by being divided into short sections by a section ID such as a disk number and a track number. In other words, the feature story video data of each program is composed of a permutation of a number of video sections corresponding to the section ID . In particular, in the index information in the ledger of the video database in this embodiment, the division ID at the head of each program is managed.
[0014]
=== Overview of audiovisual reproduction processing ===
Upon receiving a music request via the user interface device 6, the central processing unit 1 manages the IDs of the music in a queue in the order of input of the requests. When the ID of the music to be played is determined, the karaoke data corresponding to the music ID is extracted from the karaoke database, and the included music performance data is transferred to the music generator 7 to generate karaoke accompaniment music. The generated karaoke accompaniment music and the singing voice of the singer collected by the microphone are mixed by the audio device 8, and sound is output from the speaker. Prior to the series of karaoke accompaniment music generation processes, a video start process described later is performed to determine a video reproduction start point. In the video memory, lyrics images based on the lyrics data are sequentially developed in synchronization with the generation of the karaoke accompaniment music, and a lyrics caption image in which the color of the lyrics characters to be sung changes is generated. In parallel with this, the feature story video data is reproduced from the video segment at the start point, the lyrics subtitle video generated in the video memory is superimposed on the reproduced video, and synthesized and displayed on the display 9.
[0015]
When the performance of the music ends, the video stop processing described later is performed, and the video segment at the stop point is updated and recorded as the start point of the video reproduction of the next music. In this way, the story video data is reproduced from the stop point of the previous music and displayed when the next music is performed, so that the continuation of the program can be watched. Hereinafter, a detailed description will be given with reference to the flowchart of the series of video and audio reproduction processing shown in FIG.
[0016]
=== Video start processing ===
When the music to be played next is determined by the management of the performance queue (step 201 in FIG. 2), the central processing unit 1 starts preparation for playing the music and refers to a video display section history book described later. It is confirmed whether or not this music has been recorded (step 202). The case where the music has been recorded in the history record will be described later (steps 210 to 214). If this song has not been recorded in the history record, the starting point of the story video reproduction is determined according to the following procedure.
[0017]
A start point register is assigned to the RAM, and the section ID recorded in the register indicates a start point of video reproduction in the middle of the program. The central processing unit 1 retrieves the recorded section ID with reference to the start point register (step 203). If nothing is recorded in the start point register, the programs included in the video database are presented to the user in a list, and one of them is selected and inputted, and the user refers to the video database to check the program. The first section ID of the program is extracted.
[0018]
When the extracted section ID is determined as the start point of the video reproduction, the video after the start point is reproduced in chronological order of the feature story video data (step 204), and the karaoke performance of the music is started (step 204). Step 206), the lyric subtitle video of the music and the reproduced video are combined and displayed on the display 9. If the program is reproduced and displayed to the end during the performance of the music, the program may be reproduced and displayed again from the beginning.
[0019]
Note that the video reproduction start point may be a video section several sections before, for example, about five sections before the section ID extracted from the start point register. Alternatively, the feature-length story video data is divided into video sections including a plurality of video sections having a semantic unit in advance, and delimitation information (section ID of a breakpoint) is added thereto, and extracted from the start point register. A section ID that is a breakpoint immediately before the section ID may be used as a start point. In this way, the story of the video is not easily hindered, and the continuity with the video reproduced in the previous song can be confirmed.
[0020]
=== Video stop processing ===
If the music has been played to the end of the music performance data or the user has stopped playing and the performance processing has been stopped (step 207), the central processing unit 1 stops playing the video (step 208). The segment ID of the video segment being reproduced at this time is updated and recorded in the start point register (step 209).
[0021]
In the above-described video start processing, when determining the video reproduction start point, the method of appropriately setting the start point before the segment ID extracted from the start point register has been described as an example. A method may be used in which the section ID before the point is appropriately updated and registered in the start point register, and the same effect as described above can be expected. In this case, in the video start processing, the section ID extracted from the start point register may be used as the video reproduction start point as it is.
[0022]
=== Video display section history record ===
In the above-described video start processing, when the start point of the video to be reproduced during the performance is determined, the start point segment ID is associated with the music ID and recorded in the video display section history book allocated to the RAM (step 205). FIG. 3 illustrates a video display section history list.
[0023]
When the music recorded in the video display section history book is selected again, the section ID of the start point recorded corresponding to this music ID is extracted (step 210), and this is used as the start point of the video reproduction. (Step 211). At the same time, a karaoke performance is started (step 212), and the reproduced video is combined with the lyrics subtitle video of the music and displayed on the display 9. By doing so, if the user wants to watch the same program again from the same place, the user can watch the same music by selecting the same music.
[0024]
Note that in the case of processing for music recorded in the video section history book, even if the karaoke performance processing is stopped and video playback is stopped (step 214), the stop point category ID is set as in step 209. Update recording is not performed in the start point register. Also, needless to say, there is no need to record again in the video display section history book as in step 205. For example, it is assumed that music pieces A, B, and C have already been played, and the start points (section IDs) of video reproduction recorded in the history record are a, b, and c, respectively . Then, it is assumed that d has been recorded as the division ID in the start point register when the music C has finished playing. When music B is played again thereafter, the start point of video reproduction is b based on the record in the history record. When a new music piece D is played thereafter, the start point of video reproduction is set to d based on the record in the start point register. At the time of the second performance of the music B, the record of the history book does not change. In this way, the same music can be viewed from the same location (video segment) of the same program no matter how many times the same music is selected.
[0025]
=== Others ===
The songs are classified in advance according to classification categories such as melody (enka, pops, animation, western music, etc.) and song material (nature, love, life, sake, etc.), and feature-length story video programs are classified into categories. Alternatively, a program corresponding to the category of the selected music piece may be reproduced. For example, when a song A whose category is enka is selected, a program α prepared in association with the enka category is reproduced. Next, when the music B whose category is pops is played, the program β prepared in association with the pops category is reproduced. When a song C whose category is enka is selected as the third song, the continuation of the program α reproduced in the first song A is reproduced. When the song D whose category is an enka is selected as the fourth song, the continuation of the program α is reproduced following the third song, and when the song E whose category is Pops is selected as the fifth song, the second song B is selected. Is continued from the program β reproduced in step. In this way, if a plurality of programs are intermittently played back in parallel in a time-division manner, different programs can be seen for each category, and if a song in the same category as the already played song is selected, the category is You can watch the continuation of the program corresponding to.
[0026]
Further, in this case, the songs may be classified so as to belong to a plurality of categories. For example, there is a case where each music piece is classified not only by the above-mentioned music tone but also by the theme of the song. Some songs may belong to two categories, for example, enka and sake. If the selected song belongs to a plurality of categories, the central processing unit 1 randomly selects one of the songs and reproduces the program in accordance with that category. Because it is not known in advance whether or not will be played, the game will increase and it will be interesting.
[0027]
The feature story video data may be accompanied by audio data such as sound and sound effects. For example, a headphone connection terminal for listening to an audio signal generated from the acoustic data with headphones and a headphone amplifier for controlling an audio signal to be output as sound to the headphone connection terminal are provided in the audiovisual entertainment system, and a headphone connection is provided. If sound is output to the headphones through a predetermined user interface such as connecting headphones to the terminal, the enjoyment of the viewer increases. Also, commercially available movie DVD software or the like can be used, which is very convenient.
[0028]
