Midi signal is formed by state byte with more than the data byte of a byte.According to state byte, midi signal mainly is divided into the communication information, system information and change events (meta event) (representing) in table 1.Channel information is divided into acoustic information and pattern information, and system information is divided into Proprietary Information, general information and real-time information.For the purpose of easily manufactured, change events is an information of using the MIDI data set.The purpose of change events is to transmit the delta data that is not expressed as midi standard.

As shown in Figure 2, channel information represent to have the musical instrument of tone and stress or passage note beginning and stop.

Fig. 2 is illustrated in the data layout of the channel information in the MIDI data.In Fig. 2, channel information 200 comprises: note on/off data 200a, channel data 200b, phonemic notation data 200c and speed data 200d.

The on/off of note on/off data 200a control musical instrument particular note, its particular note is to be represented by the channel data and the phonemic notation data that adopt note on/off data.

The same with the data of the type that determines musical instrument, channel data 200b decision is from the tone color of the accompaniment signal of accompaniment signal generator 24 generations.

The equipment that accompaniment signal generator 24 adopts such as compositor, and have the ability of handling 16 to 32 passages, the i.e. ability of 16 to 32 musical instruments.

Phonemic notation data 200c indicates the tone of the musical instrument of being represented by channel data 200b, and speed data 200d determines the stress of represented note.

Fig. 3 represents to use the example of the passage 15 with lyrics demonstration control data.In Fig. 3, be used for the lyrics and show that the channel information of controlling 300 comprises note on/off data 300a, channel data 300b, lyrics show tags 300c and tone color tone data 300d.Theing contents are as follows of lyrics show tags.

1) show tags: this mark is used for showing the indication of the lyrics information of next amount on screen;

2) eliminate mark; This mark is used for eliminating the indication of the lyrics information of the amount that just is being shown at present on screen;

3) tone color mark: this mark is used on screen the indication of the lyric characters that conversion continuously just is being shown at present.

By channel information 300 is set, the lyrics that are used for the note of the approaching corresponding lyrics show control, and the tamber transformation of lyric characters is accompaniment signal ranks.

In addition, because a first song is from the place that the tone color mark at first occurs, thus the start time of song just can accurately represent from the accompaniment start time to the time that at first occurs when the tone color mark and count down to downwards again before the song start time by means of counting.

Fig. 4 represents to be stored in the accompaniment data in the accompaniment data storer 10 of Fig. 1.In Fig. 4, label 40 expression guides start information, each expression system clock of label 42a to 42c, label 44 expressions of accompaniment beginning partly to accord with the lyrics show tags that on/off information and label 46 expressions occur for the first time.

As at the byte signal that sexadecimal number " F8 " is arranged as shown in the table 1, system clock 42a to 42c is being divided into producing every 1/4th notes of 24 duration.Therefore, the time between sound accompaniment starting point and song starting point just can take advantage of count results to obtain with system clock cycle by the system clock 42a to 42c of the first time appearance of counting from the sound accompaniment starting point to tone color mark 46.

The cycle of system clock is not by channel information or system information but is learnt by change events (meta event).Change events is from the byte signal of sexadecimal number " FF ", and system clock cycle moves expression with little.

Fig. 5 represents the counting operation held by the controller shown in Fig. 1 32.At first, in step 500, controller 32 is read the accompaniment data that is stored in the music program in the accompaniment data storer 10, to produce the accompaniment signal or to show lyric characters.

In step 510, calculate the time (T) between occurring the first time of accompaniment starting point and tone color mark.

In step 520, count the time that is sent to accompaniment signal generator 24 with accompaniment data.

In step 530, before song begins, determine whether it is the schedule time (n).This program turns back to step 520 till reaching the schedule time (n), so begin at step 540 counting display operation.

In step 540, count value outputs to lyrics signal generator, to represent visual counting operation.Be expressed as order in this decimal system count value and reduce value.Can be with one of per second or the successively decreasing to calculate downwards and reduce value of unit any time.For example, counting beginning before three seconds, on lyrics signal generator with continuous displayed value " 3 ", " 2 ", " 1 " and " 0 ".

In step 550, verification song starting point.The song starting point can be that " 0 " or inspection tone color mark first time appearance point are discerned by determining whether calculated value.If also do not reach the song starting point, this process turns back to step 520.

In step 560, in case reach the song starting point, stop counting, controller 32 is removed the count value that is shown by control lyrics data storer 12 and lyrics signal generator 14.At this moment, when showing that count value is removed, the user begins to sing and can catch the beginning of song thus.

Fig. 6 A to 6E represents the variation according to the counting process displayed image.At this, for example, begin downward counting three seconds before leaving the song starting point.

As mentioned above, calculate the time of between accompaniment starting point and song starting point, asking according to video-song accompaniment apparatus of the present invention.Then, this device counting offers image output device to count value from song start time of accompaniment beginning, making things convenient for the user, so the user just can be easily begins the song of singing from starting point accurately.
