前面已經解釋過，所謂的互動影音內容222，就是搭配主節目影音內容212一起播放的一些動畫。舉例而言，互動影音內容可以是一種養成遊戲。此時，上述互動節目選擇器424根據評價E選擇互動影音內容方式，可以像這樣：當使用者(歌者)在KTV包廂內點播慢拍情歌，螢幕上除了原版音樂錄影帶的畫面之外還會出現一位女性或卡通人物。若使用者走音或節拍錯誤，畫面上的女生臉色會越來越陰沉，最後轉頭走人。反之若消費者音準正確且音量適中，畫面上的女生會越來越開心，最後心花怒放成為專屬歌迷。當然，這只是一個例子，互動影音內容的畫面不一定是卡通，由實景拍攝的畫面亦可，且不一定只於出現人物，任何形式的影音內容皆可。As explained above, the so-called interactive video content 222 is some animation that is played along with the main program video content 212. For example, interactive video content can be a development game. At this time, the interactive program selector 424 selects the interactive video content mode according to the evaluation E, and can be like this: when the user (singer) orders the slow love song in the KTV box, the screen is in addition to the original music video screen. A female or cartoon character will appear. If the user moves or the beat is wrong, the girl's face on the screen will become more and more gloomy, and finally turn around and leave. On the other hand, if the consumer's pitch is correct and the volume is moderate, the girls on the screen will be more and more happy, and finally they will become the exclusive fans. Of course, this is just an example. The picture of interactive audio and video content is not necessarily a cartoon. The picture taken by the real scene can also be used, and it is not necessarily only for the appearance of characters, and any form of audio and video content is acceptable.
上述的主節目動畫處理部410可進一步闡述如下。The above-described main program animation processing unit 410 can be further explained as follows.

If you then divide each score into three levels, there are a total of 27 ratings. The score animation comparison table 224 specifies the correspondence between the different evaluations and the plurality of interactive video content 222. For example, for the 27 evaluation results, the corresponding interactive video content 222 is specified.
根據圖7的評分動畫對照表224的一個例子可看出，如果由樂聲評分單元300輸出的評價E為音調+1分、歌詞+1分，音量+0分的話，就會對應到動畫10-2，於是互動節目選擇器424，就會在多個互動影音內容222中選取動畫10-2，並傳送到第2影音解碼器422。According to an example of the scoring animation comparison table 224 of FIG. 7, it can be seen that if the evaluation E output by the musical sound scoring unit 300 is the pitch +1 score, the lyrics +1 score, and the volume + 0 score, it corresponds to the animation 10 -2, then the interactive program selector 424 selects the animation 10-2 among the plurality of interactive video content 222 and transmits it to the second video decoder 422.
此外，也可以在前奏和結尾的地方，按照評價E所累計的總分來指示對應的互動影音內容。例如參照圖7在前奏和結尾的時候，按總分的高、中、低，來指定到不同的互動影音內容222。當然上述圖7只是評分動畫對照表224的一個例子，本發明並不限定評分動畫對照表需有音調、歌詞、音量的評價，可以更多，也可以更少，且每個評價也不限定為三等級，可以更多，也可以更少。In addition, it is also possible to indicate the corresponding interactive audio and video content according to the total score accumulated by the evaluation E at the prelude and the end. For example, referring to FIG. 7 at the prelude and the end, the different interactive video content 222 is assigned according to the high, medium, and low of the total score. Of course, FIG. 7 is only an example of the scoring animation comparison table 224. The present invention does not limit the evaluation of the pitch animation, the lyrics, and the volume, and may be more or less, and each evaluation is not limited to Three levels, more or less.
針對選播互動影音內容222的方式，還可再進一步闡述如下。請參照圖8，其為圖6的互動節目動畫資料庫的更詳細的例子。圖8與圖6的主要不同在於，圖8進一步繪示了互動節目導航檔。The manner of selecting the interactive audio and video content 222 can be further elaborated as follows. Please refer to FIG. 8, which is a more detailed example of the interactive program animation database of FIG. The main difference between FIG. 8 and FIG. 6 is that FIG. 8 further depicts an interactive program navigation file.
如圖8，多個互動影音內容222舉例而言，可包括前面已說明過的至少一音評互動動畫222a，或者再進而包括至少一定時互動動畫222b。請注意，雖然為了方便說明而在圖8中一併示出了222a、及222b，但本發明並不限定需要同時具有兩者，只有音評互動動畫222a亦可。As shown in FIG. 8, a plurality of interactive audiovisual content 222, for example, may include at least one of the soundtrack interactive animations 222a, or further including at least a certain time interactive animation 222b. Please note that although 222a and 222b are shown together in FIG. 8 for convenience of explanation, the present invention is not limited to the need to have both, and only the sound review interactive animation 222a may be used.
互動節目動畫資料庫220，舉例而言，還可包括互動節目導航檔226，其中該互動節目導航檔226指定出在不同的播放時間點所需對應播放的互動影音內容222。The interactive program animation library 220, for example, can also include an interactive program navigation file 226, wherein the interactive program navigation file 226 specifies interactive audio and video content 222 that is required to be played at different playback time points.
按照圖8的例子看來，當互動影音內容222包括了音評互動動畫222a、定時互動動畫222b時，互動節目導航檔224指定出在某些播放時間點要播放定時互動動畫222b，而在某些播放時間點要播放音評互動動畫222a。互動節目選擇器424按照互動節目導航檔224的指定，在不同的播放時間點選擇對應的互動影音內容222，並輸出到第二影音解碼器422。According to the example of FIG. 8, when the interactive video content 222 includes the sound review interactive animation 222a and the timed interactive animation 222b, the interactive program navigation file 224 specifies that the timed interactive animation 222b is to be played at some playing time points, and The sound review interactive animation 222a is played at some play time points. The interactive program selector 424 selects the corresponding interactive video content 222 at different playback time points according to the designation of the interactive program navigation file 224, and outputs the corresponding interactive video content 222 to the second video decoder 422.
