: : I WANT TO MAKE VCD/MP3/ACD PLAYER ALL BY MYSELF. I WANT BRIEF NOTES OF HOW VCD/MP3/ACD PLAYER WORKS ?
: Basically this kind of stand alone player consists of following part:
: 1. CD reading hardware (typically nowadays a computer CD-ROM drive mechanics and alectronics)
: 2. Controllign microcontroller (reads user controls, controls displays, sends commands to Cd drive, rreads data from drive and sends it to decoder circuitry)
: 3. Signal decoding circuitry that takes in the compressed digital data and outputs analogue signal or digital uncompressed data signal (MP3 decoder IC, MPEG decoder IC etc.)
: 4. User interface (buttons, display, etc.)
: 5. Power supply
: 6. Case where everything is put in
: You can find plans to build MP3 players at

: I do not have any plans for VCD player.
