TOKYO, Japan, November 10, 1997 ----- Pioneer announced its
introduction of the "DV-S9" DVD-Video player (price: \190,000 / launch schedule: mid Dec.1997 / production: 1,000pcs per month), positioned to be the flagship model of its consumer use DVD-Video product line-up, to the Japanese domestic market.

Planning Concept

After a year has passed since DVD was introduced to the Japanese market, the number of DVD software titles have been increasing at a high pitch with predictions of approximately 500 titles by the end of 1997. Not only the software market, but also the DVD market as a whole is growing day by

In November 1996, Pioneer introduced five consumer use DVD players, 3 DVD-Video players and 2 DVD Karaoke players, which is the largest line-up found in the industry. With the use of State-of-the-Art technologies and user-friendly features in its products, Pioneer has made its way to be the
top share brand in the industry.

Pioneer has developed the DV-S9 DVD-Video player to answer the needs of the main DVD buyer, the so-called "Enthusiastic User", who expect on a much higher performance model.

The DV-S9 applies all the Optical Disc and Audio-Video technology Pioneer has fostered over years. Newly developed LSIs are adopted to devotedly reproduce picture with full fidelity. For audio sound features, the technologies developed for high-end CD players are incorporated to achieve hi-quality sound. All, which make the DV-S9 a true flagship, model in Pioneerfs DVD-Video line-up.


Main Features

1. Four Newly Developed LSI Chips to Reproduce Hi-quality Picture and Audio

*Viter-bi RF Decoder
The data processing LSI contains Pioneerfs original error correction  system to improve correcting ability up to a maximum 1/1000 data error   evel, by using statically analyzed parameters through RF (Radio   Frequency) data reading.

*AV1 Chip MPEG Decoder
The AV1 Chip MPEG Decoder combines the MPEG2 decoder and audio decoder   into a single chip resulting to reproduction of a hi-quality picture and   audio with no interference to analog signals.

*Component Frame DNR IC
The Component Frame DNR (Digital Noise Reduction) IC provides a drastic   reduction of video noise, and a cleaner more articulated on-screen image.

*10bit Accurate NTSC Encoder and 10bit Video DAC IC The NTSC Encoder and Video DAC (digital to analog converter) IC will   provide a consistent D/A conversion process of 10bit video data into   equivalent analog signals to result in a high picture quality. The   adoption of a 10bit type has made even more precise calculation compared   to a conventional 9bit type.

2. Parameter Control Technologies for Clarity and High Quality Images

*Component Frame DNR
It is essentially the same as a 3-dimensional frame correlative DNR,   featuring a frame memory to store the data for a frame previous to the   current one. The DNR compares the previous frame in memory to the current
frame, point for matched point, to detect noise. If the difference between   the matched points in the compared frames is less than a reference value,   it represents noise. The difference signal is then subtracted from the
current frame, while itfs also output to and stored in the frame memory   for noise detection in the next frame. If, on the other hand, the   difference between two compared points is greater than the reference   level, the DNR assumes that the image is moving and the difference signal   is simply output to the current frame. With the DV-S9, Luminance (Y),   Chroma blue (Cb), and Chroma red (Cr) components of a video signal undergo
the process of noise reduction individually.

*Y/C(Chroma) Timing Adjuster
The DV-S9 features the Y/C Timing Adjuster to compensate for the    difference of phase between luminance and chroma signals recorded on a   disc.

*Sharpness Control
The circuit enhances the level of a low-level signal the DNR identifies as   a visual signal, and adds sharpness and detail to the picture (both   vertical and horizontal resolution can be adjusted individually in 9   levels).

*D-Extension Control  The circuit makes black still blacker. By extending down the signal toward
the black level, it adds depth to images and also improves contrast.

*Noise Reduction  Special noises that get emphasized when motion picture software is
digitally edited will be reduced.

Chrominance Level Control  Fine Chrominance level adjustment can be made in 9 levels.
