TECHNICAL DESCRIPTION

4-4 Recorder Signal Processing

< BACK END >IC2300

• The DVD coding circuit and MI-COM circuit are integrated in a single chip.

• Video/audio data is coded through use of the IC2304 and 2305 (DDR SDRAM).

The internal MI-COM circuit carries out front-end (DVD drive) control.

The recorded signals to DVD (read-out) are handled by the front end through ATAPI communication for which the IC2306

(DDR SDRAM) is mainly used.

< FRONT END>DVD DRIVE

• At the time of recording, video/audio data fed from the back end is modulated to DVD recording data, and a DVD write control

operation is performed.

• At the time of playback, data is read out from DVD, and demodulation is performed together with error correction.
