  3. Motivation • Learn how to use two new languages. • Create something fun that we could use in the future. • Take something bulky and expensive and make it work on an Iphone. • Profits (potentially)

  4. Team Members and Tasks • Daniel Kirschner: Server Side • SQLite database • Apache server • David Pinho: Iphone Side • UI • Playing MP3+g files • Both: Implementation • Connection from Iphone to SQLite database

  5. File Format • Most popular karaoke files are MP3+G and CD+G files. • Can be created with standard MP3’s with a program readily available. • File size 3-6mb depending on song length.

  6. Server • Hold’s MP3+G files in one location instead of storing on the Iphone. • Quick and easy access to songs without having to buy each one separately or finding them elsewhere.

  7. Developing Environment • 2 PC’s with Mac OS X 10.6 on them. • We will be coding for the Iphone using objective-c on the Iphone SDK. • Using Apache to host server located on Dave’s second PC. • We will be coding a SQLite database to organize the music stored on the server.

  8. User Environment • The user will be using an Iphone using OS 3.1.3 • Browse by album, by genre, or alphabetically. • Search through the SQLite database • Play MP3+G with the option to fast forward and volume control. • Television or projector connection will be plug and play.
