Similar in purpose to
a recordable CD jukebox, the MP3-based digital record
and playback device is a home stereo style device. This device is capable of
real-time recording and compression of incoming audio, capable of
encoding of CD audio from an incorporated CDROM drive, plays locally
stored MP3 files. This device can locally store MP3 files from ISO-9660 CDROMs, and
is accessible via a standard FTP network protocol. It is possible to
create play lists from local files. Audio input and output connections
are in the form of RCA analog audio and S/PDIF digital. This device makes use of DSPs, microcontrollers, hard disk
access, CDROM control, development of a custom file system, digital
signal sampling, a display controller, user input and output, network
management, power fault tolerance, and digital and analog I/O.
