BMC Mechanical Deck

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

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.

High-Speed, High-Precision Servo DSP

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.

Fig. 22: The drive system uses an uncommonly powerful 40 MIPS DSP,

combined with an uncommonly accurate Delta Sigma 1-bit D/Aconverter.

DVD Technical Notes

Performance Meets Refinement

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 TEXTTM 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.
