Abstract (en)
[origin: WO0167448A1] A universal compact disc (CD) player having the ability to decode and play an encoded audio file residing on a CD, regardless of the particular encoding algorithm used to encode the audio file, consists of: a spindle motor (12, 16) and optical pickup (14, 18) adapted to read the signal recorded on the CD; an amplifier (20) to amplify the signal read by the pickup; a programmable digital processor (24) adapted to decode the amplified signal under the direction of a decoding software program; a nonvolatile memory (26, 28) containing the decoding software program directing the operation of the digital signal processor; a program adapted to read the decoding software program from a memory card (32) into the nonvolatile memory; a digital-to-analog converter (34) to convert the decoded signal into an analog audio signal; and a speaker (38) or headphones (40) to convert the analog audio signal into sound.
