This board implements the back-end circuitry of a DVD player. It is composed of the following
subsystems:
* Microcontroller which does main control to all other sub-blocks of the system including user
interface, driver interface, audio/video output.
* Vaddis A/V Decoder IC decodes the bitstream coming from the DVD front-end drive, and
Optionally performs audio and video effects.
* Audio Codec
