ES DVD Players 2005, Version 4.0 Page 2 Intr oduction Sony ES engineers are superbly educ ated, exceptionally well equipped and have ready access to world-leading in-house technologies. But these alone do not explain the soul of Sony's ES Se ries.
ES DVD Players 2005, Version 4.0 Page 3 i.LINK ® and HDMI™ Digital Interfaces In 1985, the engineers of Sony® ES surprised the world of high fidelity. The Sony CDP-650ES was the world's first CD transport with a digital output, enabling unheard-of sound qual ity and unprecedented flexib ility in audio system configuration.
ES DVD Players 2005, Version 4.0 Page 4 Typical SA-CD reproduction involves numerous D/A and A/D conversions. The i.LINK digital c onnection can simplify the s ignal path. However, these analog connections can expose the Super Audio CD signal to repeated D/A and A/D conversions.

ES DVD Players 2005, Version 4.0 Page 8 An HDMI™ plug and its corresponding jack. To begin with, many DVDs originate on film or progressive scanning video. These discs are encoded in 480p progressi ve scanning to deliver twice the vertical resolution as conventional 480i video.
ES DVD Players 2005, Version 4.0 Page 9 The options for audio are equally ri ch. The HDMI™ output of Sony® ES Series players can support a full range of digital audio, including 2-channel stereo PCM, Dolby® Digital and DTS® 5.
ES DVD Players 2005, Version 4.0 Page 10 Finally, the components agree on the hi ghest available quality options for digital audio and video—and t hen automatically transfer c ontent at that quality! We've considered just a DVD player and a television.
ES DVD Players 2005, Version 4.0 Page 11 V ideo P erfor mance Precision Cinema Progressive™ circuitry The purpose of today's high-end home theater systems is to recreate the look and sound of the movie theater. This includes t he vivid detail and seamless coherence of the film frame.
ES DVD Players 2005, Version 4.0 Page 12 The mathematical algorithms of Sony's Pixel-by-Pixel Active I/P conversion have been commit ted to silicon in this Large Scale Integrated circuit (LSI), the Sony CXD9866R. Sony solves the problem with Pixel- by-Pixel Active I/P conversion that includes built-in motion det ection.
ES DVD Players 2005, Version 4.0 Page 13 • Film and video material shown simultaneously. The Sony® system performs beautifully even when film and video appear on-screen at the same time, for example, when video-originated subtitle s are superimposed over a film-originated scene.
ES DVD Players 2005, Version 4.0 Page 14 Pixel-by-Pixel Active I/P conversion and interlaced video origination Many of today's DVDs feature c oncert videos, documentaries, current events, sports, nature f ootage and other subjects originally captured on interlaced video.
ES DVD Players 2005, Version 4.0 Page 15 The typical interlaced video frame includ es both still and moving pixels. Sony Pixel-by-Pixel Active I/P conversion applies se parate processing for each. • Pixels for still objects are the easiest to handle.

These Sony® ES Se ries DVD players achieve a remarkable combination of superb fine picture detail and excellent clarit y, thanks to 216 MHz oversampling in the D/A converter.

ES DVD Players 2005, Version 4.0 Page 22 Noise Shaped Video™ circuitry While 216 MHz sampling deals with noise outside the video frequency range, another circuit reduces noise within the frequency range. That's important because the perceived transparency and depth of the video image depends on controlling noise.

ES DVD Players 2005, Version 4.0 Page 25 To maintain the purity of the signa l, Sony places the analo g video circuitry on a separate board, dr iven by its own power supply. Because digital noise can corrupt the DC voltage, the power supply is another potential path of interference.
ES DVD Players 2005, Version 4.0 Page 26 High speed video buffer ampl ifiers (NS9100ES) If your television accepts an HDMI™ cable, you can enjoy a fabulous all- digital video connection. If not, you'll be happy to note that Sony® engineers are passionate about achieving excepti onal performance from analog video connections.
ES DVD Players 2005, Version 4.0 Page 27 Carefully selected parts (NS9100ES) More than a labor of technolog y, the DVP-NS9100ES represents the enthusiasm that Sony® engineers share with high-end videophiles. That's why the player incorporates a variety of carefully selected resistors, inductors, semiconductors and capacitors.
ES DVD Players 2005, Version 4.0 Page 28 Audio P erf or mance In addition to DVD-Video and Compact Discs, these ES Series DVD players also reproduce sumptuous high-resolution audio: both stereo and multi- channel Super Audio CD music. You'll hear the inner detail of choral ensembles.
ES DVD Players 2005, Version 4.0 Page 29 Speaker Time Alignment For optimum playback, the masteri ng engineers who create CDs need to anticipate the speaker confi guration over which the music will be reproduced. In stereo, that configuration is simple: tw o identical speakers ideally set an equal distance from the listener.
ES DVD Players 2005, Version 4.0 Page 30 Incidentally, this adjustment is not duplicated on most A/V receivers. Some receivers can adjust for speaker di stance on the multi-channel signals that are decoded in the receiver itself. But most receivers offer no such adjustment for the 5.

ES DVD Players 2005, Version 4.0 Page 37 Audiophile-grade components (NS9100ES) Two capacitors with identical circuit values can have quite different sound quality. For this reason, Sony® engineers have taken the time to choose top- quality audiophile-grade components thr oughout the DVP-NS9100ES.
