What is What is DVD-Audio?DVD-Audio?

The new audio standard developed for thenext generation, based on

DVD-Video ROM technology.It offers 4 major characteristics:

CONSENSUS:Developed by the DVD forum, together with the ISC(International Steering Committee), this format issupported by the music industry as the next-generation standard in digital audio.

ULTRA-HIGH QUALITY 2-CHANNEL STEREO:Offers unprecedented audio quality, with a maximum192 kHz sampling frequency and 24 bit quantization.

MULTI-CHANNEL WITH LINEAR PCM QUALITY:Since it supports up to 6 separate audio channels, itcan reproduce movie soundtracks and other multi-channel content with full impact.

VISUAL & INTERACTIVE CONTENTS:Enables future-oriented interactive capabilities,including still image playback, digital effects, visualmenus, and much more.

High-bit (24 bit) QuantizationSupporting 24 bit quantization, DVD-Audio offers apotential dynamicrange of 144 dB(theoretically),allowing productsthat deliver a 110 dB or broaderdynamic range.

Up to 192 kHz Sampling FrequencyWith a maximum sampling frequency of 192 kHz,DVD-Audio performance dramatically surpassesAudio CD quality.48*/96*/192 kHz, 44.1*/88.2*/176.4 kHz aresupported for stereo content. Support of 44.1 kHzand derivative frequencies maintains compatibilitywith the Audio CD family.

*Supports multi-channel content also.

FlexibilityTo offer content producers the flexibility they need,DVD-Audio permits various parameters such assampling frequency, quantization and numberof channels to be changed per each track.

Established in 1995, the DVD Forum’sWG-4 (Working Group 4), chaired by JVC,developed the DVD-Audio standard inconsultation with the ISC which represents the 5major software producers that account for 90%of the world’s music market.

Flexibility for Content Producers

Multi-Channel and StereoBoth multi-channel and stereo versions of the sameaudio can be stored in the same track; the userselects which version to listen to.If only multi-channel content exists on a disc whilethe user wants to listen in stereo, DVD-Audiosupports multi-to-stereo downmixing to allow stereolistening. Based on an algorithm stored on the disc,multi-channel sound can be converted to stereo inthe manner intended by the content producer.

Linear PCM and Packed PCMIn addition to Linear PCM which offers the highestquality for stereo content, DVD-Audio also supportsPacked PCM (a.k.a. MLP™ or Meridian LosslessPacking) to accommodate the higher data amount ofmulti-channel content. For example, Packed PCMwill allow 86 minutes of 96kHz/24bit/6ch content perdisc, which is impossible with Linear PCM.

Linear PCM 6-Channel CapabilityIn addition to stereo, the DVD-Audio format alsosupports multi-channel Linear PCM audio of up to6 channels. Available speaker settings areL/R/C/Ls/Rs/LFE, thereby offering compatibilitywith 5.1 channel surround sound systems.

Content producers can choose to divide thechannels into groups (e.g. front group and reargroup) and give them different parameters(sampling frequency and quantization) to allowmore efficient use of disc capacity.

n Track Text displays information specific to thetrack being played in real-time.

Bonus GroupContent producers can include “bonus groups” onthe disc that can be played only if a key number iscorrectly input. Unlike bonus tracks on CDs, thesebonus groups require user interactivity to access,and can be tied-in with various promos such ashaving the user visit a Web site for the access key.

Also, if supportedby the player, digitaltransition effectssuch as Fade, Wipeand Dissolve canbe applied to thepictures.

Still Picture PlaybackWhile playing audio tracks, it is possible to viewMPEG2 or MPEG1 digital still pictures that arepart of the disc’s content.

The capacity of a DVD-Audio disc currently is 4.7Gbytes, and some content providers may opt touse a two-sided disc to double the content volume.With high quality, and the ability to store high-capacity data very efficiently, the DVD-Audio formatis an excellent medium for the latest audio andmultimedia productions.

VVideo Perideo PerforformancemanceFeaturFeatureses

DVD-Video offers a solid, high-quality base forvideo images. The XV-D723GD is equipped withvarious technologies that maximize thispotential quality.

JVC Progressive Scan Output● Conventional : 2-3 Pull-Down Interlaced ConversionMost movies on DVD are recorded at 24 frames persecond (24fps) in MPEG format. A conventionalinterlaced DVD player converts 24 frames per secondinto 30 interlaced frames (or 60 fields) for display on aTV. Frame-for-frame conversion, however, would resultin a wrong playback speed, so a technique called “2-3pull-down” – which alternates two video fields (oneframe is made of two video fields) with three videofields for each pair of DVD frames – is used to producethe 30 necessary frames. But this causes two fields tobe blended in the same frame, resulting in blurryimages in fast-moving scenes. And since the picturesare interlaced, scanning lines are noticeable on the TVscreen, and vertical resolution is low.

● JVC Advantage : Direct Progressive Scan OutputThe common progressive converter used on someDVD players first converts progressive 24fpsrecorded on DVD into interlaced 30fps (2-3 pull-down conversion). Then the I/P(Interlaced/Progressive) converter LSI re-convertsthe interlaced 30fps into progressive 60fps. Thistwo-step conversion can lead to the deterioration ofthe signal-to-noise ratio and resolution.JVC’s Direct Progressive Scan Output features the“Direct Progressive Decoder” – a newly-developed high-speed MPEG decoder that canproduce the video output at twice conventionalspeed. This allows the direct conversion ofDVD’s 24fps into progressive 60fps for displayon your TV, thereby avoiding the qualitydisadvantages of I/P conversion. (See comparisondiagram on next page.)

FOR DEMO:

1 Play a movie on DVD.2 Pause the picture at a scene where there are

large, bright, same-colored fields.3 Switch back and forth between Interlace to

Progressive; point out how scanning lines arevisible in Interlace, and disappear inProgressive.

4:4:4 Upsampling of DVD SignalEnsures clearer and purer color reproduction.To maximize color reproduction accuracy, DVD’soriginal 4:2:2 (Y Cr Cb) component signal isupsampled to 4:4:4. Since this signal is alsooversampled to 54 MHz for output, greatlyimproved color reproduction is achieved.

Even during interlaced output, the combination of54 MHz DAC and 4:4:4 upsampling deliversbeautiful images with increased depth in the overallpicture.

Unique characteristics:● Does not use an expensive I-P conversion LSI.● Incorporates newly developed high-speed MPEG

decoder and 10-bit/54 MHz DAC in a single chip.● Controlled by RISC (Reduced Instruction Set
