These waveforms were taken with the player turned on and no disc in-

serted. They show that the CD DOut data signal (ch 2) from IC303/pin

110 is fixed to half of the bit clock frequency (ch 1).

A/V Decoder IC401

Purpose

Video

·MPEG decompression using the external IC402 and IC403 memo-

ries.

·Crops the 16x9 image for a 4x3 TV picture (software dependent).

·Communicates with IC202 with servo control changes to get info at

different parts of the disc.

·On screen display graphics.

·D/A Converter (analog video output).

·Generates MacroVision copyguard signals when instructed.

Audio

·MPEG audio decompression

·Dolby Digital AC-3 decompression using external SRAM IC402 / IC403

Outputs:

·6 Analog Video channel Outputs (Y, B-Y, R-Y, Composite, Y, C)

·6 channels of Dolby Digital (AC-3) audio with clock signal support.

Flash ROM IC205

Contains fixed data about how this DVD player should store, retrieve and

process information. SYSCON IC202 processes this information. Some

of the information processed is as follows::

·Some variables in the MEPEG Video and AC-3 Audio processing

·What ICs to check during start up

·Stores the power ON DVD Sony logo

·Test mode overall operation (servo data is in IC201)

·Color bars used in the test mode (main picture)

·Menu languages and characters
