ES Series DVD-Video/CD/SA-CD Players Technical Background Version 3.0; June 2, 2003.
ES Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 2 Introduction In 2002, the Sony DVP-NS999ES DVD player established an entirely new Reference Standard for the category.
ES Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 3 Video Performance Precision Cinema Progressive™ circuitry (all models) 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 Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 4 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 CXD9698R. Sony solves the problem with Pixel- by-Pixel Active I/P conversion that includes built-in motion det ection.
ES Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 5 system instantly recognizes the c haracteristics and film and video and automatically applies the corre ct processing for each. • Film and interlaced video-originated material in the same scene.

ES Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 7 The typical video frame inclu des pixe ls from on-screen objects that can are still, moving and moving slowly.

ES Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 9 Sony's Pixel-by-Pixel I/P conversion overcomes this problem by employing a third mode conversion mode, specifically for slow motion.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 10 there's a big difference in contrast between the areas they separate. Rooflines, car hoods, venetian blinds and other lines in the scene can appear with unwanted stair steps not in the original program.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 11 The 14-bit video D/A converter also includ es the video encoder and processing for Macrovision™ Copy Protecti on. Sony applies the extended binary word length both to DVD's luminance (Y) black-and-white channel and to DVD's two color difference channels (P B and P R ).
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 12 MHz). This means that DVD samp les the video luminance channel at 13,500,000 Hz (13.5 MHz), as part of t he DVD-Video format specification.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 13 For progressive scanning, running the D/A converter at the mini mum frequency of 27 MHz makes it extremely c hallenging to design the analog low-pass filter. T he filter (red curve) must be steep to avoid cutting into the video signal (blue) or in cluding some of the noise ( pink).
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 14 Oversampling at the 216 MHz fr equency of the DVP-NC555ES and DVP-CX777ES is even more dra matic The DVP-NC555ES and DVP-CX777ES go further still, all the way to an amazing 216 MHz oversampling.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 15 Noise Shaped Video and th e higher 108 MHz and 21 6 MHz sampling frequencies work together to cut video noise for improve d transparency and clarity.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 16 "Below Black" rep roduction (all models) The DVD format dictates specific quantization for specific brightness levels. For example, full black corre sponds to a quantization of 16 while full white corresponds to 235.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 17 settings to memory. The DVP-NS999ES has memory for 300 discs. As a 400- disc changer, the DVP-CX777ES has memo ry for all 400 discs.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 18 High speed video buffer ampl ifiers (DVP-NS999ES) While Sony can control the video si gnal inside the DVP-NS999ES, there's one aspect we can't control: the cables that convey the signal to your television.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 19 from the start. You get reliable operation without performance-robbing output capacitors. Carefully selected parts (DVP-NS999ES) More than a labor of technolog y, the DVP-NS999ES represents the enthusiasm that Sony engine ers share with high-end videophi les.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 20 Audio Performance In addition to DVD-Video and Compact Discs, all of these models also bring home sumptuous high-resolution aud io, playing back both stereo and multi- channel Super Audio CDs.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 21 Multi-channel DSD decodi ng is handled by a Sony Large-S cale Integrated circuit (LSI), the CXD2753R. It's another of many exclusive Sony LSIs in the ES Series DVD players. Multi-Channel Management (all models) Home theater speaker configurat ions vary considerably.

ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 23 Sony's powerful CXD9722 han dles both Speaker Time Alignment and A/V alignment. 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.

ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 26 Audio Shield Plate (DVP-NS999ES) The DVP-NS999ES prevents even minute interference between the analog video and analog audio circuit boards. The boards are separated by a substantial shield plate that includes a copper sheet to block radiation.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 27 Sony's choice of a grounded AC input assur es a more stable electrical and mechanical connection.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 28 without the voids or gaps that permit vibrati on. This results in far less radiation, far less hum. All ES Series DVD players use an R-Core transfor mer. The transformer pictured here powers the audio circ uits of the DVP-NS999E S.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 29 Construction Quality Anti-resonant chassis design (all models) Vibration is the enemy of CD, DVD and Super Audio CD players for two powerful reasons. First, vibration in t he disc or optical pickup triggers unwanted operation in the tracking servos.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 30 A generous application of anti -resonant damping materials to the top and sides of the DVP-CX777ES case.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 31 to perimeter, this tends to vary the resonant frequen cy within the foot—diffusing one potential path for vibration. To furt her deaden vibration, t he feet of the DVP- NS999ES use non-rebound rubber on the bottom.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 32 generation of this ground-break ing design. In Sony's mechanism, the spindle, motor and optical pickup base unit are rigidly bolted to a sub-chassis, to reduce any possibility of resonance.
ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 33 addressed this by creating a hermetic shutter. It forms an airti ght seal to protect the disc and pickup from air-borne vibrat ion. Even when the speakers in your room are going full blast, the di sc rotates in peace and quiet.

ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 46 Theatrical release movies aren't the only programs that are originally captured at 24 frames per second on motion picture film. For example, music videos, TV commercials and primetime dramas are often shot on film or film-like 24-frame progressive video.

ES Series DVD-Video/CD/SA-CD Pl ayers; Version 3.0 Page 48 The 24P encoding of film-originated DVDs means that 3-2 pulldown must be performed in the DVD player before the picture can be displayed on a conventional television. The exact patte rn of 3-2 pulldown can have a subtle effect on the rendering of mo tion.
