Design of Multi-Singing Karaoke System and its Application in Customer Finance-aided Service on Internet

Financial engineering nowadays is heavily depending on the real-time investment decision-support system while providing the suggestions to investors for rebalancing their portfolios. Because of the rapid growth of interactive technologies in Internet, on-line customer finance-aided service (CFAS) is playing an important role to help discussing, exchanging valuable information or enjoying entertainment each other simultaneously based on the platform of multi-singing karaoke system. Today´s online singing software allows only one-microphone performance. Duo singers can only take turns and use the same microphone. Also, they cannot hear each other simultaneously. This is one big disadvantage of online multi-singing software, hence brings the problems to the quality of CFAS. Therefore, the main purpose of this study is to create a system that allows several singers to sing in different places simultaneously and hear the other singers´ voices at the same time. This system catches and analyzes the singers´ signals from remote computer sources through Media Server. Also by network broadcasting, this system transmits the signals from the inviter´s end to the invitee´s end, which is deeply improving the quality of CFAS
