    1. i.LINK is a trademark of Sony used only to designate that product contains an IEEE 1394 connector. All products with an IEEE 1394 connector may not communicate with each other.
  • Page 4 NS9100ES overcomes this limitation. The i.LINK interface maintains the signal in the digital domain, protecting the music from repeated conversions. This i.LINK digital output is compatible with the i.LINK digital input on Sony's own STR-DA7100ES and the recent STR-DA9000ES. The i.LINK interface also enables a single digital cable to take the place of six analog cables.
  • Page 5 Internal layout of the DVP-NS9100ES as seen from the back. You can see the edge of one of the R-Core power transformers (1), the analog audio circuit (2), and the analog video circuits (3). The digital audio circuit board (4), which includes and the i.LINK output is partially hidden behind the analog video circuit.

  • Page 6: High Quality Digital Audio

    STR-DA7100ES DVP-NS9100ES With Sony® HATS, audio data flows from the player to the receiver's buffer memory, according to rate control commands from the receiver. Reproduction in the receiver achieves the full time base accuracy of the receiver's quartz crystal master clock.

  • Page 8 In addition to providing 480p, 720p or 1080i, the HDMI output of Sony® ES Series DVD players can support digital signals in both RGB component video and Y/Cb/Cr component video.
  • Page 9 The options for audio are equally rich. 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® 5.1-channel compressed audio and even uncompressed multi-channel PCM audio! The DVP-NS9100ES incorporates the awesome capabilities of the Silicon Images Sil9030 Large Scale Integrated Circuit (LSI).
  • Page 10 Thank you We've considered just a DVD player and a television. But the dynamic changes when you insert the Sony® STR-DA7100ES A/V receiver into the reproduction chain. In this case, the source component DVD player can only talk to the next component in the chain, the receiver. The receiver then communicates with the television and mediates the content exchange for the entire system.

  • Page 11: Video Performance

    Video playback with progressive scanning, "480P" output. This works with many of today's "HD capable" and "HD monitor" televisions, which offer 480P inputs. For example, Sony markets this capability as a Hi-Scan 1080i™ television. In this context, 480P outputs have been promoted as a must-have feature in DVD players.
  • Page 12 In this case, conventional 3-2 reverse conversion will not work, but Sony's Pixel-by-Pixel Active I/P conversion will. Thanks to built- in motion detection, the Sony system does not depend on FFRFs. So you get accurate reproduction on DVD-R/RW and DVD+R/RW discs.
  • Page 13 For this reason, Sony's Pixel-by-Pixel Active I/P conversion applies special processing for video originated material. In addition, these Sony ES Series DVD players enable you to adjust the threshold of film and video detection. So you can optimize the I/P conversion for the specific DVD you're watching.
  • Page 14 If not done properly, this can result in zipper-like edges on moving objects, line flicker and unnatural shimmering. Sony's Pixel-by-Pixel Active I/P conversion overcomes these problems with built-in motion detection and two distinct video conversion algorithms: one for still objects, another for moving objects. As with film origination, the algorithms are applied separately for each individual pixel.
  • Page 15 Still Part Moving Part The typical interlaced video frame includes both still and moving pixels. Sony Pixel-by-Pixel Active I/P conversion applies separate processing for each. • Pixels for still objects are the easiest to handle. When objects are not moving, the player can simply use the corresponding pixel from the previous field.
  • Page 16 As before, your setting for each disc can be stored in memory. Vertical Edge Compensation As we've seen, Sony's Pixel-by-Pixel Active I/P conversion of video sources suppresses the zipper-like effect that can occur when moving areas of two interlaced fields are combined in the same progressive frame. It's a major step forward in picture quality.
  • Page 17 Most people would not notice the artifact without being told when and where to watch for it. But Sony's program for these ES components required us to address even subtle distortions.
  • Page 18 Longer word lengths contribute to smoother, more realistic transitions from dark to light. Starting with the DVP-S7000, Sony led the way with 10-bit video digital-to- analog conversion. The DVP-NS900V raised the performance to 12-bit conversion, producing four times the grayscale levels. The DVP-NS999ES incorporated the Analog Devices ADV7304A, a 14-bit video D/A converter.
  • Page 19 These Sony® ES Series DVD players achieve a remarkable combination of superb fine picture detail and excellent clarity, thanks to 216 MHz oversampling in the D/A converter.
  • Page 20 And at 108 MHz (third from top), the filter becomes better still. Oversampling at 216 MHz (bottom) leads to a far more effective analog low-pass filter. This enables the Sony® ES Series DVD players to deliver all the picture detail, without degrading the clarity of the image with noise.

  • Page 21: Sampling Frequency

    The filter either cuts into the video detail (blue) or passes some of the noise (pink). Oversampling at the 216 MHz frequency of the Sony® ES Series DVD players makes a huge difference. Oversampling has been used successfully in CD players for decades.
  • Page 22 That's important because the perceived transparency and depth of the video image depends on controlling noise. Sony's D/A converter uses Noise Shaped Video circuitry to shift noise from inside the visible frequency range to outside. Even though the overall noise level remains the same, the perceived noise is dramatically reduced.
  • Page 23 As with an audio equalizer, aggressive adjustment can yield unnatural results. The controls are best used to make gamma curves that are smooth and subtle. Sony's control offers eight points of correction, each with 8-bit precision. And you can always return the gamma controls to the industry-standard "flat"...
  • Page 24 Video Equalizer Sony's Video Equalizer enables you to fine-tune the picture quality of each disc you watch. You can adjust Picture, Brightness, Color, Hue and Chroma Delay in addition to Graphical Gamma Adjustment. And once you've optimized the picture for a particular disc, these ES Series DVD players can commit your settings to memory for up to 400 discs.
  • Page 25 To maintain the purity of the signal, Sony places the analog video circuitry on a separate board, driven by its own power supply. Because digital noise can corrupt the DC voltage, the power supply is another potential path of interference. That's why early on, Sony recognized the advantage of giving the analog circuit block its own series power supply.
  • Page 26 High speed video buffer amplifiers (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 exceptional performance from analog video connections.
  • Page 27 DVP-NS9100ES. Oversized output resistors. Output resistors determine the impedance of the analog output circuits. Most designers avoid large resistors. But Sony incorporates large resistors of uncommonly tight tolerances. This contributes to the high slew rates required for wideband video.

  • Page 28: Audio Performance

    DSD® decoder LSI The Super Audio CD’s 1-bit signal is processed and decoded by Sony's DSD decoder LSI. This integrated circuit makes intelligent decisions regarding processing of the incoming data to form the 1-bit audio signal. The LSI first reads the Watermark—a feature protecting Super Audio CDs from illegal...
  • Page 29 (DSP) that adjusts the arrival time of each channel with delay in 900- microsecond increments. Because most people can't make the mental leap from microseconds to speaker distance, Sony calibrates the delay as distance, in 30- cm (1-foot) increments. Each 900 microseconds of delay "moves" a speaker back 30 cm (1 foot).
  • Page 30 Multi-channel Super Audio CDs present the player with six separate channels—all recorded with exactly the same superb quality as two-channel Super Audio CD. That's why the Sony® ES Series DVD players incorporate six channels of Sony's Super Audio D/A Converter (SA DAC). The circuit delivers superlative performance for multi-channel SA-CD, two-channel SA-CD and CD reproduction.
  • Page 31 1 bit/64 fs filter 1 bit/64 fs Sony's Super Audio D/A Converter (SA DAC) does an equally superb job on Compact Disc signals (top) and SA-CD signals (bottom). The converter consists of a single integrated circuit that contains four significant circuits: 1.
  • Page 32 For this reason, technologists developed 1-bit D/A converters that bypassed the problem completely. Significant among these 1-bit designs was Sony's own High Density Linear Converter™ circuit, which made its debut on the ES DVD Players 2005, Version 4.0 Page 32...
  • Page 33 Such distortion was not acceptable for the design program of the ES Series DVD players. That's why Sony® ES engineers endowed the SA DAC with Sony's multi-level D/A conversion. Unlike the multi-bit conversion used at the dawn of the digital age, multi-level conversion exhibits superb low-level linearity.
  • Page 34 Multi level D/A conversion Multi level D/A conversion N= 64 (for spec 1) The SA DAC uses multi-level D/A conversion, illustrated here. Like multi-bit conversion, the multi-level system uses many switches operating in parallel. Unlike multi-bit designs, the value of all switches is identical—a binary 1.
  • Page 35 DVD player are potential sources of radiated noise. Low-level signals in the analog audio circuits are particularly susceptible to this noise. That's why Sony isolates the analog audio circuits on their own board. It's one more measure to help maintain the purity of both DVD-Video sound tracks, and Super Audio CD music.
  • Page 36 Sony's careful design not only maintains the sonic purity of multi- channel Super Audio CD signals, but also preserves the crucial left/right and front/rear symmetry of 5.1 DVD-Video surround signals. A separate printed circuit board for analog audio employs six separate, identical circuits to handle the 5.1 channels of output.
  • 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 throughout the DVP-NS9100ES. The op amps, resistors, capacitors and more have been individually selected and matched for their sound quality.
  • Page 38 Video Off and Display Off modes One potential concern with so many types of circuitry in one chassis is mutual interference. Sony minimizes the possibility of radiated interference with power-off configurations that shut down potential sources of noise: Video Off: Shuts down the video circuitry and the HDMI™ output to eliminate even slight residual effects on the audio circuitry.

  • Page 39: Construction & Design

    Power transformer cores and windings can vibrate and degrade the sound, radiating 60 Hz hum into nearby audio circuits. That's why Sony chose an R- Core design. The R stands for round. Not only is the core round, it has a cylindrical cross section, enabling the transformer windings to be wrapped without the voids or gaps that permit vibration.
  • Page 40 That's why the DVP-NS9100ES is built upon the formidable foundations of Sony's New Base and Pillar (NBP) chassis. In Sony's previous Base and Pillar (BP) chassis, pillars stand on a metal panel base, to which side and top panels are installed. This design bolsters the strength of the bottom panel (the base), achieving high rigidity in a simple structure.
  • Page 41 Silver Cascade Design In addition to its remarkable technology, the DVP-NS9100ES continues the "cascade" faceplate design exclusive to the Sony® ES Series. The design sets all the primary controls at an angle, so that you can identify each control and use the player without uncomfortable bending.
