DVD Technical Notes

For further protection, the mechanical deck is insulated from the

DVP-S9000ES main chassis via dedicated supports.

A new Digital Signal Processor (DSP) handles 40 million

instructions per second (40 MIPS). The result is highly precise

control of the optical pickup, for supremely accurate readout of

the high-density DVD and SACD signal surface. The new DSP

also helps deliver superb high-speed search and special effects

playback. And it helps reduce the duration from disc insertion to

the start of playback.

This digital controller must speak to such analog devices as the

disc drive motor, tilt motor, and thread motor. For this purpose,

the system uses 20 MHz Sigma Delta modulation and a highly

linear 1-bit D/A converter. The result is 10-bit accuracy in the

motor control output voltages.

The base unit is mounted on a subchassis called the mechanical

deck. On the DVP-S9000ES, this is a self-contained box formed

of Sony’s Bulk Molding Compound (BMC). Long a fixture in

Sony anti-resonant design,

BMC is carefully

formulated for high strength

and high internal loss. Like

steel, it has the rigidity

required for its structural

purpose. But unlike steel,

BMC steadfastly resists

vibration and resonance.

BMC consists of calcium

carbonate — a principal

component of marble — glass

fiber reinforcement and

unsaturated polyester. The

material is subjected to

thermosetting and is formed into the mechanical deck floor, walls

and ceiling. Even the disc loading tray is made of non-resonant

BMC.

Mechanical Deck Insulators

High-Speed, High-Precision Servo DSP

Thoughtful touches and operating refinements make the

DVP-S9000ES a pleasure even before playback begins.

Thick aluminum front panel. The DVP-S9000ES has serious,

down-to-business styling with a thick, uncluttered aluminum

front panel. The fluorescent display window is made of high

hardness acrylic resin, especially formulated to resist scratches.

Short stroke controls. Front-panel buttons are designed to

respond to the lightest finger contact. Audio feedback in the

form of a defeatable beep tone confirms each command.

LED/fluorescent display dimmer. To minimize distraction

during movie playback, the front panel fluorescent display can

be dimmed. When you dim the display, the player

simultaneously dims the front panel LEDs.

Control Menu. With DVD-Video, SACD and CD playback

in a single chassis, the DVP-S9000ES is brimming with control

options and configuration possibilities. Sony organizes all the

options for maximum clarity and presents them on your

television screen.

Luminescent remote control. Because owners will be

enjoying DVDs with the room lights turned down, the remote

control features glow-in-the-dark keys for Play, Stop, Pause

and Display.

Sound feedback. Beep tones confirm your selections for both

front-panel and remote control commands. If you prefer, the

audio feedback can be deactivated.

Picture Memory. Similar to the customizable desktop picture

on a PC, the DVP-S9000ES can display different scenes in the

Stop mode. These can include favorite video scenes stored in

memory, along with jacket pictures from CD Extra discs as

well as DVDs.

Bit Rate Display. Users can track the variable bit rate of

MPEG-2 compression with on-screen displays of video and

audio bit rates.

Layer and Pickup Display. The DVP-S9000ES can show an

on-screen graphic representation of your current position on

the disc, along with your current layer for dual-layer discs.

Custom Parental Controls. You can password protect the

viewing of up to 300 DVDs, restricting playback to PG

versions (on compatible discs) or preventing playback

altogether.

DVD, SACD and CD TEXT

TM

display. The DVP-S9000ES

provides scrolling front panel display for the text functions of

compatible discs.

Enviromentally friendly. To conserve energy, power,

consumption in the Standby mode is less than 1 watt.

Operation automatically shuts down 30 minutes after Stop.

To reduce pollution, the printed circuit boards are halogen-free.
