頸問題， 讓使用者透過智慧型手機隨時隨地下載Karaoke伴唱影音並歌唱； 在歌唱的同時， 將使用者的歌聲上傳至伺服器， 透過即時影音合併技術， 將Karaoke伴唱影音與使用者的歌聲合併，再以即時影音串流的方式分享至他人的行動裝置或個人電腦，可以讓其他人即時觀賞與收聽使用者正在演唱的歌曲。

With the growing popularity of smart phones, the entertainment services for mobile phones are more and more important than before. There are Karaoke services on the Internet nowadays but the services are
only available for users who use PCs. Besides, the users’ singing voice cannot share to their friends at the same time. Thus, it’s an important issue to enjoy Karaoke services by using smart phones and to share users’
singing voice with their friends anytime and anywhere. This study proposes the mechanism that provides users to download the karaoke videos and to sing anytime and anywhere through cloud architecture. In addition, the user’s singing voice can be uploaded to the server. The karaoke video and the singing voice will be merged into the respective video which will be shared with the others in streaming on their mobile devices or PCs.
