碩士 === 國立臺灣大學 === 資訊網路與多媒體研究所 === 97 === Along with the prosperous developments of computer science and technology, there are a large number of applications of virtual environment have been realized in people’s daily lives. People could learn some specific subjects or knowledge, such as playing music, driving a vehicle, exercising and so on, via these applications. However there is no proper and mobile DJ (Disc Jockey) relevant application be implemented nowadays. Based on this point, the “Virtual Mobile DJ” system is implemented on an embedded system in this thesis. During construction procedure of the system, we explored on Linux sound system, the UDA1341 codec, OSS (Open Sound System) driver on an embedded system environment, and how to control MP3 format data on an embedded system without hardware support. And then a proper and clear user interface made by Qt GUI framework is proposed. Finally, a user could manipulate the “Virtual Mobile DJ” system by touching the interactive touch-screen GUI functionality in embedded system platform.
