Compression Block: ADPCM: From • Transient analysis time to • Vector analysis freq • Prediction analysis Converter Global Bit Management Variable Length Coding Global Bit Management Once compression has taken place, an examination of the six data streams for density is made. Bit groups are tagged and moved from a high-den- sity channel to a low-density channel equalizing the amount of data.
Block Diagram There are four major stages within this DVD player. They operate in this sequence to produce the discs’ video and audio: · Power Supply · Communications · Servo Control · Video and Audio Processing Power Supply The power supply block delivers five different voltages. Ever 5V is the only voltage present when the unit is plugged into AC.

Communications Block Both serial and parallel bus structures are used in the same unit of today’s DVD players. The serial data bus is a simple way to provide communica- tions between ICs. On one line, data is transmitted one bit after another to the next IC in 8, 16, 20, 24 or 32 bit groups.

Mechanism Disc Tray and Laser Platform Position Tray Movement The loading motor moves the disc tray in or out. Without the tray, the loading motor’s shaft is seen on the right side. Teeth Pawl Channel Tray Bottom Top View The rotation of the motor turns the three gears to its left. The final gear at the far-left mates with the teeth on the tray.
No Power Tray Removal – From the Top 1. Remove the two screws and the mechanism’s top cover to expose the tray and laser platform. 2. Locate the top pawl under the tray by inserting a small screwdriver between the platform and tray. The pawl is just in front of the spindle motor.

Initial Sled Motor Drive Initial Sled Movement Start When the laser’s platform is lifted to a level position, the disc is sand- wiched between the spindle motor table and the magnet. In this position the disc is said to be “chucked”. The chucked position requires System Control IC202 to retrieve the initial sled program stored in EEProm memory IC201 (not shown) via the parallel bus.

Sled Driver IC802 Sends Voltages to the Stepper Sled Motor When the input pulses to pulse Sled motor Driver IC802 are not identical to the input reference, the sled motor is driven.
Laser Servo After the disc tray is closed (disc chucked/platform up), the laser is turned on. The laser on command takes this six-step path from IC202: 1. System control IC202 2. HGA IC601 3. Servo DSP IC701 4. DVD/CD RF Amplifier IC00 5.
KHM-220A DVD Optical Block Sony DVD players had two independent laser assemblies. One was used to play DVD and the other used to play CDs. In 1999, a single DVD laser in the KHM-220A block was used to play both discs. There were two additional G &...
Single F o c u s 1.1 cm Point C D F O C U S C O R R E C T E D Three Laser Beams from One Laser Although there is one laser, there are three spots of light on the disc’s information layer.
The extra detectors are to permit this laser assembly to read DVD-R discs in future players. This DVD player cannot play DVD-Recordable discs even though the laser has the ability to do so. Detectors E & F are added together and treated as one.
SACD Disc Type SACD stands for Super Audio Compact Disc. Although this DVD player can detect the SACD disc, it can only play its normal CD layer (number two). The first layer can contain six channels of uncompressed audio and...

Focus Mechanical focus of the laser beam on the information layer of the disc is accomplished by moving the laser’s objective (final) lens closer to or away from the disc. Applying a current to a coil that is attached to the lens controls the lens position.
Focus Drive Servo IC701 outputs two square waves from pins 80 and 85 as long as the set is powered. The reference square wave comes from pin 80 and is fixed at 50% duty cycle. When the duty cycle of pin 85’s waveform changes, the focus coil receives current.

Spindle Motor The spindle motor has a “kick” mode and a run mode. The kick mode is used to start and stop the motor, bringing the motor up to speed or to a stop quickly. The CLV PB mode utilizes the pits on the disc surface to regulate the spindle motor speed.

CLV PB Mode In the CLV PB mode, IC001, IC303 and IC802 are used to regulate the spindle motor speed. System Control IC202 issues a CLV run command to IC303. By this time, the disc has reached data output speed so IC303 can use the data to govern the spindle motor.

Tracking Servo The purpose of the tracking servo is to keep the laser beam positioned at the center of the disc’s data (stream). This is achieved mechanically by attaching a lightweight coil of wire to the laser’s objective (final) lens. This coil faces a stationary magnet.

Sled Motor Drive - PB Initially during disc search, just System Control IC202 data was used to move the sled motor. During playback, IC202 data and tracking error are used to handle the sled movement. The choice is dependent upon the location of disc information.

When the model DVP-S530 DVD player is first plugged in and turned on, several things occur before “NO DISC” is displayed on the front panel. One operation is performed after the next until it reaches the end of the chain. A failure will prevent it from reaching the end and often a side trip is taken to protect the unit by shutting down.
