system instantly recognizes the characteristics and film and video and automatically applies the correct processing for each. Film and interlaced video-originated material in the same scene. The Sony system performs beautifully even when film and video appear on-screen at the same time, for example, when video-originated subtitles are superimposed over a film-originated scene. Because the Sony system analyzes each individual pixel, it can switch processing modes anywhere even in the middle of a field! In contrast, conventional systems need to wait until the end of the field before switching between film and video modes. Interlaced video originated material. Shooting on conventional, interlaced video means capturing a new field of 240 interlaced scanning lines every 1/60 second. When subjects are moving, there can be significant differences from each field to the next. It's a far cry from film origination, where the subjects move each 1/24 second. Combining two video-originated fields of 240 interlaced scanning lines into one frame of 480 progressive scanning lines is no simple task. For this reason, Sony's Pixel-by-Pixel Active I/P conversion applies special processing for video originated material.
An on-screen display enables you to adjust the threshold of film and video detection for each individual disc. Sony ES Series DVD-video players can even store your setting for use the next time you play that title!
In addition, the DVD-Video players of Sony ES 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. You get I/P conversion that's not only amazingly smooth, but also exquisitely tuned to the individual needs of each DVD. When you're done watching, the players can store the setting in memory. So each time you play that title, you'll automatically get just the right conversion!
Three I/P conversion modes for interlaced video origination (all models)
Many of today's DVDs feature concert videos, documentaries, current events, sports, nature footage and other subjects originally captured on conventional, interlaced video. Video based I/P conversion creates new pixels from existing information. For example, to enable progressive scan output of an odd video field, the player must create the pixels that compose all the even

Page 5

scanning lines. Unfortunately, this can result in motion blur. Horizontal lines in the scene can flicker on and off. Other areas can suffer from an unnatural shimmer. For this reason, any high-end progressive scanning system must solve the problem of motion artifacts for footage shot on video.

Scanning lines

EVEN future
I/P conversion of interlaced video originated material. The red pixel, on an even scanning line needs to be created for the current, odd field. 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 three distinct video conversion algorithms: one for still objects, a second for moving objects and a third, just for slow-moving objects. As with film origination, the algorithms are applied separately for each individual pixel. So all three can be applied to different parts of any given scene!

Still Part

Moving
The typical video frame includes pixels from on-screen objects that can are still, moving and moving slowly. Sony Pixel-by-Pixel Active I/P conversion applies separate processing for each.
Still pixels are simply created from the corresponding pixel in the previous field.
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. Because there is no motion, these pixels will match perfectly with the current field, creating a seamless progressive scan output.

Page 7

Moving pixels are created by composing adjacent pixels in the same field. This minimizes motion blur.
Pixels for moving objects are created by composing pixels from scanning lines immediately above and below within the same field. Because all information comes from the same 1/60-second slice of time, this suppresses motion artifacts. While this process does not result in the full improvement in vertical resolution, the human eye is less sensitive to detail in moving objects. Many conventional I/P conversion algorithms have these two modes: still and motion. What's more, the two modes can even coexist in a single frame, sometimes on a pixel-by-pixel basis. However, when objects are moving slowly, the compromise in resolution can be noticeable. And when slow-moving objects come to a complete stop (or still objects go into slow movement), the sudden shift in resolution can be noticeableand annoying.

Sony employs a third mode, specifically for slow-moving pixels. These are created by a sophisticated hybrid algorithm, based on seven adjacent pixels.

Page 8

Sony's Pixel-by-Pixel I/P conversion overcomes this problem by employing a third mode conversion mode, specifically for slow motion. Slow-moving pixels are composed via a sophisticated hybrid algorithm from seven pixels on adjacent lines and fields, to reduce motion artifacts and annoying resolution shifts to a minimum. This mode delivers superlative resolution on objects that are moving slowly, stopping and starting. So the overall effect is a stunning improvement in image detail, clarity and solidity. Because the motion detection system operates pixel-by-pixel, the ES Series players can employ all three algorithms simultaneously, to optimize every area of the video scene. Still backgrounds are impressively sharp and detailed, while moving objects in the same scene are free from motion artifacts. And slowmoving objects don't shift in resolution. You'll see more consistent, more satisfying, more seamless 480P output with a wider variety of discs. The visibility of scanning lines is all but eliminated. Connect a 480P-compatible television, monitor or projector and prepare to be amazed. You'll approach the full glory of high definition picture qualityfrom today's standard DVDs. Just as you can adjust the threshold of film/video detection, you can optimize the still/motion detection for the specific requirements of the DVD you're watching. As before, the player can memorize your Still/Motion threshold for favorite discs. So each time you play a title, you'll automatically get just the right conversion!
You can adjust the Still/Motion detection threshold with this on-screen display. As before, you can store your setting for favorite discs in memory.
Vertical Edge Compensation (all models)
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. But there is a second, less obvious artifact that can occur in part of the video image part of the time. Most people would not notice the artifact without being told when and where to watch for it. But Sony's program for the ES Series required us to address even subtle distortions. The problem is jaggedness in the edges that separate areas of the scene, especially when the edges are straight lines, when they're diagonal and when

Wide pitch output jacks (DVP-NS999ES, NC555ES)
Sony engineers even anticipated the high-grade output cables that videophiles are likely to use. On the DVP-NS999ES and NC555ES, Sony deliberately spaced the Y/PB/PR output jacks further apart than common practice, the better to accommodate heavy-gauge cables and plugs!
The spacing or "pitch" between the component video output jacks is wider than usual, to accommodate heavy-gauge cables and plugs.

Audio Performance
In addition to DVD-Video and Compact Discs, all of these models also bring home sumptuous high-resolution audio, playing back both stereo and multichannel Super Audio CDs. You'll hear the inner detail of choral ensembles. The reverberation trailing from a guitar chord. And the acoustic space surrounding the instruments. With Super Audio CD, you hear every nuance of sound reproduced with incredible ease and clarity. (For the full story on Super Audio CD and its innovative Direct Stream Digital encoding process, please see Appendix B.)
Multi-channel Super Audio CD playback (all models)
Sony ES Series DVD-Video players take full advantage of the latest generation of multi-channel Super Audio CD music. Multi-channel Super Audio CD gives producers the ability to capture the precise ambience and reverberation that give any concert hall, jazz club or recording studio its characteristic "sound." Multi-channel Super Audio CD doesn't just bring the performer to your room; it puts you into the performer's space. The result can be overwhelming. By combining this fully dimensional soundstage with the uncanny clarity of DSD technology, Sony ES Series DVD players offer music reproduction that's nothing short of brilliant.
DSD decoder LSI (all models)
The Super Audio CDs 1-bit signal is processed and decoded by Sony's CXD2753 DSD decoder LSI. This integrated circuit makes intelligent decisions regarding the incoming data to form the 1-bit audio signal. The LSI first reads the Watermarka feature protecting Super Audio Compact Discs from piracyand then decodes the incoming data. The LSI uses internal memory to take data that's output intermittently from the disc, rearrange it and order it into continuous 1-bit audio streams. This LSI also reads sub code data such as the Table of Contents, track number, track time, and text data.

Page 20

Multi-channel DSD decoding is handled by a Sony Large-Scale 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 configurations vary considerably. Some enthusiasts have built upon audiophile-grade stereo systems. These systems may have large, full range Left and Right speakers that produce bass so deep that any subwoofer would be extraneous. In this case, the Left and Right speakers may well be considerably larger than the Center and Surround speakers. Other systems may have five matching satellite speakers, plus a subwoofer. Some systems may have no Center channel speaker, while others have no Surround speakers. The DSD decoder LSI provides multi-channel management to achieve optimal multi-channel reproduction with all these speaker configurations.
Speaker Time Alignment (all models)
For optimum playback, the mastering engineers who create CDs need to anticipate the speaker configuration over which the music will be reproduced. In stereo, that configuration is simple: two identical speakers ideally set an equal distance from the listener. In a multi-channel sound, the ideal is slightly more complex. Multi-channel Super Audio CD is designed to conform to an international standard, called ITU-R. This envisions that the listener sits in the exact center of a circle of five identical speakers, with each speaker occupying a specified position in the circle. (For the Low Frequency Effects or LFE channel, the subwoofer can be flexibly placed outside the circle.) The ITU-R circle makes a great reference for studio engineers. But few home environments can accommodate exactly this setup. Even if you did have five identical speakers all the way around, the rectangular shape of most rooms

Page 21

would make it difficult to place all five speakers at equal distance from the listening position.

30 110

Mastering for Super Audio CD multi-channel sound assumes that speakers will be placed according to the international ITU-R standard (left). Unfortunately, most practical listening rooms don't match this standard exactly. Speaker Time Alignment applies a delay to selected speakers to "move" them into proper position (right). In this example, time delay pushes back the apparent position of the SL and SR speakers to match the L, C and R speakers.
To resolve the problem, Sony developed a 1-bit Digital Signal Processor LSI, the CXD9722. This LSI enables you to apply a carefully timed delay to each individual speaker. Sony provides this delay in 150-microsecond increments. Because most people can't make the mental leap from microseconds to speaker distance, Sony calibrates the delay as distance, in 5-cm (2-inch) increments. Each 150 microseconds of delay "moves" a speaker back 5 cm (2 inches). In this way, Speaker Time Alignment adjusts the "virtual position" of each speaker, enabling you to synchronize the arrival time of sound for all five speakers. You can even change the perceived distance of the subwoofer in relation to the other speakers. With Speaker Time Alignment, you'll experience multi-channel sound as it was meant to be heard. You'll get the effect of perfect speaker placement, even if your actual placement is far less than perfect!

High performance audio D/A converters with DSD inputs (all models)
To elicit the full sound quality from Compact Disc, DVD-Video sound tracks and especially from Super Audio CD, these DVD players incorporate powerful audio D/A conversion technology. The D/A converters can handle DSD inputs for Super Audio CD playback as well as high quality DVD-Video signals up to 192 kHz sampling rate with 24-bit word length. This assures compatibility with the widest range of source material. The DVP-NS999ES offers even more, with separate Sony D/A converters for multi-channel and stereo programming. Both of these D/A converters include on-board Variable Coefficient digital filters for extremely accurate rendition of the soundfield on DVD-Video and CD. In addition, on-board DSD filters reduce highfrequency noise in Super Audio CD playback. Finally, both D/A converter ICs employ multi-level delta-sigma D/A conversion, which assures both excellent linearity and remarkably low noise. Balanced outputs on the DVP-NS999ES D/A converters enable balanced transmission of audio signals to the post Low Pass Filter on the audio circuit

board. This suppresses noise caused by fluctuations in the power supply and other externally-induced voltages.
On the DVP-NS999ES, the Sony CXD9675R (left) is a high performance audio D/A converter for 5.1-channel output. A separate D/A converter, the Sony CXD9674TN (right) serves two-channel stereo sources.
Separate analog audio circuit board (DVP-NS999ES, NC555ES)
The digital audio, digital video, analog video and servo control circuits inside a 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 the DVP-NS999ES and NC555ES isolate 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. In addition, the DVP-NS999ES uses six separate, identical audio circuits to handle the 5.1 channels. This ensures uniform frequency response and gain characteristics at the output. 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.
On the DVP-NC555ES, a separate printed circuit board for analog audio employs six separate, identical circuits to handle the 5.1 channels of output.

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.

This substantial, copper-lined shield plate protects the analog audio board from even subtle distortions caused by the analog video board.
Wideband digital outputs (DVP-NS999ES)
To deliver a high quality digital signal, the DVP-NS999ES employs a widebandwidth optical module. It can achieve transmission speeds over 13 Megabits per second. This offers plenty of headroom for the 4.6 Megabits per second required by 96 kHz/24-bit outputs. The coaxial output delivers comparable quality thanks to a high-performance pulse transformer. Both digital outputs assure superb dynamics while holding noise and distortion to the bare minimum.
Audiophile-grade components (DVP-NS999ES)
Two capacitors with identical circuit values can have quite different sound quality. For this reason, Sony engineers have taken the time to choose topquality audiophile-grade components throughout the DVP-NS999ES. The op amps, resistors, capacitors and more have been individually selected and matched for their sound quality. For example, carbon resistors with nonmagnetic leads have been chosen for their higher handling capacity. We chose film capacitors for their superior audio characteristics. We even considered the power plug. Sony engineers chose a grounded, 3-pin plug for superior mechanical and electrical characteristics.

Page 26

Sony's choice of a grounded AC input assures a more stable electrical and mechanical connection.
Gold-plated output jacks (all models)
To maximize electrical conductivity and minimize the effects of oxidation over time, the audio, composite video, S-Video and component video output jacks are plated with gold. Noise at the contact points is held to a bare minimum.
You might not notice that the output jacks are plated with gold. But they protect the audio and video signal quality from oxidation which can degrade the output signal over time. And that can make a noticeable difference.
R-Core power transformer (all models)
The video and control circuits can introduce imperfections to the power supply voltage, which can trigger audio distortions. To protect the audio circuitry, these DVD players use a separate power supply, just for audio. In addition, power supply regulation on the audio circuit board itself helps establish stable operation for the audio D/A converters. Transformer cores and windings can vibrate and degrade the sound, radiating 60 Hz hum into nearby audio circuits. That's why Sony chose an RCore 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
ES Series DVD-Video/CD/SA-CD Players; Version 3.0 Page 27
without the voids or gaps that permit vibration. This results in far less radiation, far less hum.

Responsive and accurate servo DSP (all models)
The Precision Drive 2 system of the DVP-NS999ES operates under the control of a fast servo DSP, the Sony CXD9703. It operates at 50 million instructions per second (50 MIPS), an astonishing speed for an ancillary processor. You get instantaneous response to changes in operating conditions, faster and smoother high-speed search and shortened time between disc insertion and playback.
Sony's servo DSP has an astonishingly fast operation speed of 50 million instructions per second (MIPS).
Delta Sigma 1-bit D/A in the Servo DSP (all models)
Just as Delta Sigma modulation stands behind the high sampling rates of the Super Audio CD format, Sony has applied Delta Sigma modulation to the servo DSP. The Sony CDX9703 incorporates a 1-bit Delta Sigma Modulation A/D converter to translate the analog input voltages into binary code. In order to drive the focus and tracking actuators, the output of the servo DSP is converted

Page 35

back to analog using delta sigma modulation at 25 MHz. The D/A converter exhibits superb linearity, equivalent to 10-bit precision. So you get remarkably accurate tracking on DVD, Super Audio CD and CD alike.
The Sony CXD9703 Servo DSP incorporates an on-board Delta Sigma A/D and D/A converters for exceptional tracking accuracy.

Convenience
Disc Explorer system (DVP-CX777ES)
With 400 discs of entertainment at your beck and call, the DVP-CX777ES promises that you'll never need to rummage through your shelves or fumble with jewel boxes, searching for the movies and music you want. But delivering on this promise required a fast, easy, electronic way to identify and access your discs. That's exactly what the Disc Explorer system provides. Using your television screen as a Graphic User Interface, the Disc Explorer system delivers easy, onscreen access to your discs alphabetically by title, by disc type, by genre and by "folders" that you can organize and name. The player loads information regarding your 400 discs into memory, so it's always available for instant access and display. Sort by disc type. The player automatically recognizes disc type such as DVD and CD. So you can scan discs by type. Sort by slot number. The DVP-CX777ES holds each disc in a sequentially numbered slot. The changer makes it easy to sort and access discs by slot number. Sort by title using CD, SA-CD, DVD Text and Disc Memo function. Many discs have text, including disc title, encoded on the signal layer. This information is automatically memorized and displayed by the DVP-CX777ES. In cases where discs do not already have titles, you can create titles using the Disc Memo function. You can also use Disc Memo operation to store artist name, date of purchase or other information about a disc. You can then search discs alphabetically by title. Keyboard Input. Sony gives you two ways to enter text information for each disc. Use the remote control keys to input any character or plug an industrystandard PC keyboard into the front panel connector and type! Jacket Pictures recorded onto DVDs appear automatically. If there is no jacket picture, you can create one by freezing any scene on the DVD. Sort by folders. Sony enables you to organize the 400 discs into four subgroups. While the folders are initially labeled "A" through "D," you can assign them personalized names, like DAD, KID or JAZ. Even when assigned to these custom folders, discs still appear in the standard folders for "All, "DVD," and "CD." Sort by genre. You can also sort movies and music by types. So you can immediately scroll through an on-screen list of all your Sci-Fi DVDs, for example, or all your Country Music discs. All told, Sony provides ten movie genres and six music genres, for easy sorting.

Thanks to 3-2 pulldown, movie film at 24 frames per second gets transformed to videotape at 60 interlaced fields per second. Movie frame A is converted to three fields. Movie frame B is converted to two fields. Movie frame C is converted to three fields and so on, in a 3-2-32-3-2 pattern.

Film and video on DVD

In order to fit a feature-length film onto a CD-sized disc, the DVD format employs MPEG-2 digital compression. And one important trick of this compression is to distinguish between footage originally shot on conventional, interlaced video and footage originally shot on film or 24P video. As you would

Page 46

expect, DVD stores video footage in its native 60i form. But you might be surprised to learn that most DVDs shot on film or 24P video store the images at the native rate of 24 frames per second! Like material shot on conventional, interlaced video, the typical DVD shot on film is encoded from 60i videotape. But in the DVD authoring process, logic circuits in the majority of high-quality MPEG encoders detect the telltale pattern of 3-2-3-2 in the incoming video fields, the so-called 3-2 cadence. Since repeated fields would waste precious disc space, the DVD eliminates them and replaces them with First Field Repeat Flags (FFRFs) that tell the player which fields to repeat. The remaining fields are reassembled back into their original frames and encoded onto the DVD in progressive scan at 480/24P. This system is 20% more space-efficient than 60i. It's an important advantage because it enables DVDs to hold films that are 20% longer. Or DVDs can encode each frame with 20% more bits, for even better picture quality.
The DVD stores film-originated material at 24Pthe same rate as the original film. First Field Repeat Flags (FFRFs) mark the 3-2 cadence. The DVD player then performs its own 3-2 pulldown to output images at 60i.

Page 47

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 pattern of 3-2 pulldown can have a subtle effect on the rendering of motion. So it's important that the DVD reproduce the 32 pulldown cadence of the original master videotape. That's where the FFRFs come in. They identify each field to be repeated as part of a "3."
Interlace-to-progressive (I/P) conversion
The playback of 480/24P film-originated material has a special property. In material originally shot on 480/60i video, each "B" field represents a slice of time 1/60th second after the corresponding "A" field. To the extent that objects in the frame are moving, the two fields won't match and aren't well suited for direct output in progressive scan. In contrast, 480/24P film-originated DVD is inherently progressive and is beautifully suited to progressive scan display. Ironically, most of today's MPEG decoder chips automatically convert the 480/24P progressive DVD into 480/60i interlaced video. Additional processing is required to convert the 480/60i interlaced signal into a 480/60P progressive signal for output to a compatible television. The required process is called interlace-to-progressive (I/P) conversion. Because the process operates on a digital signal in the digital domain, it can result in a super high-quality video source that promises to be the ideal complement to high-end, big-screen televisions with 480P inputs.

The DSD pulse train "looks" remarkably like the analog waveform it represents. More pulses point up as the wave goes positive and down as the wave goes negative.
Multi-channel Super Audio CD
Producers also have the option of creating multi-channel Super Audio CDs that can transport you to the acoustic space of the original recording. You'll hear the most convincing soundstage ever presented at home. Super Audio CD multichannel sound is based on the international standard ITU-R speaker setup. So it's directly compatible with many of today's home theater speaker systems. For full compatibility with pure stereo Super Audio CD players, every multichannel Super Audio CD includes a complete stereo rendition from the hand of the producer. You're never at the mercy of a computerized "fold-down" of the multi-channel mix. You'll always hear the producer's original intent.
