Method and System For Automatic Karaoke Video Reproduction

KTV, which stands for Karaoke TV, has become increasingly popular in Asian countries in recent years. Unlike MTV (Music TV) where the artist performs the singing and audience passively watch the video, KTV allows audience to sing along with the music. Moreover, considering that the amateur singer may not be able to remember all song words , almost all KTV provides lyrics which are superimposed onto video frames in form of closed captions and displayed at the exact moment when they are sung. In this context, different colors are used to display different texts in order to remind audience of their "status". A text character is in an active status if it is being sung; otherwise, it is inactive. Figure 1 shows one example where there are two text lines in the image taken from a Chinese KTV video. Specifically, notice that texts in the second line are all white, while the leading texts in the first line are blue. This implies that the first line of texts are the song words just or being sung, while the second line is still waiting to be activated. Moreover, as the audience sing along with the music, the inactive words become active and their color will turn to blue in a fairly synchronized way. Obviously, this change-of-text-color mechanism can natually and effortlessly guide audience to complete a song which they may not be familiar with.

However, the production of a Karaoke video is not cheap. In fact, it is rather expensive. To make its content attractive, a special production team is needed which selects cast, shoots video, and mixes them with the song to best interpret the music theme. Nevertheless, different people may have different tastes and preferences. Thus very often, for every single song, one can easily find multiple Karaoke videos on the market. This obviously boost the production expenses. In this context, a better approach is needed which can not only make Karaoke video customized to people's need, but also
