Updateable Message Personal CD Player - Gen 4

Drexel University

This E-Team received a previous Advanced E-Team grant for development of the X-CD system, a system that integrates wirelessly updated messages with recorded music. The X-CD is a portable CD player that receives messages broadcast over FM sub-carrier, stores them in memory, and plays them back before, during, or after any CD played, as appropriate. Listeners receive the X-CD broadcasts, consisting of story capsules, interviews, reviews, and advertisements, automatically when they use a properly equipped personal music player. Magazines, television shows and others who advertise to young adult audiences will buy air time from X-CD and provide the broadcasts. X-CD players, branded by these sponsors, and will be offered to magazine subscribers or prospective subscribers. The sponsors, magazines like Rolling Stone or Teen People, or TV shows like MTV, will then gain access to the young adult market.

To date, the X-CD E-Team has created three successful prototypes and is now ready to create a fourth generation prototype. While the first three prototypes have been PC-based, the fourth will be built around an embedded microcontroller. In the first phase of the work plan, each team member will design and build a major subsystem of the self-contained module. The end goal of this phase is that all key subsystems will function properly in isolation. In the second phase, the E-Team will integrate the subsystems into a whole. In the third phase, the team will conduct field testing, range measurements, system optimization, and concept/functionality refinement.

The X-CD E-Team consists of three computer science undergraduates. They work with an electrical engineering faculty member and the founder and president of SixtySeven Kilohertz, Inc.
