Sony S9000ES manual High Precision Video Equalizer

this, DVD players have offered a choice between frame pause or field pause. Frame pause maximizes vertical resolution, but blurs whatever motion may be present in the image. Field pause gets rid of motion blur, but sacrifices vertical resolution, just like a VCR.

Now with the Clear Frame system of Sony’s DVP-S9000ES, you no longer need to choose. Because the MPEG Image Processor already has comprehensive motion detection circuitry, the player already “knows” which portions of a video-originated scene have motion. So the player applies high-resolution frame pause for all

Fig. 10: Sony’s Clear Frame system delivers superior still images of video-originated DVDs. Moving areas, like the car are reproduced in motion-stopping field pause. But motionless areas, like the stop sign are reproduced in the full resolution of frame pause. So you see far higher pause mode resolution!

the motionless areas of your picture, while it applies motion- stopping field pause to areas of movement. Clear Frame is simple, automatic and easy to appreciate. It’s a major improvement in freeze frame technology.

High Precision Video Equalizer

The video equalizer of the DVP-S9000ES enables users to fine- tune performance to match their monitors and viewing conditions. The equalizer is controlled via on-screen display and offers unusually fine adjustment:

Picture	+/- 20 steps
Brightness	+/- 20 steps
Color Balance	+/- 20 steps
Hue	+/- 20 steps

Horizontal Sharpness	+/- 20 steps
Vertical Sharpness	+/- 20 steps
Block Noise Reduction	stages 0 to 7
Luminance (Y) Noise Reduction	stages 0 to 7
Chrominance (CB, CR) Noise Reduction	stages 0 to 7
Chroma Delay	2 stages

“Below Black” Reproduction with Graphical Gamma Adjustment

The DVD format dictates specific quantization for specific bright- ness levels. For example, full black corresponds to a quantiza- tion of 16 while full white corresponds to 235. However, demand has grown for adjustment that matches the DVD player output to the characteristics of your display. Direct-view CRTs, plasma panels, CRT projectors and LCD projectors each have specific needs. For example, LCD projectors are subject to “black float” and can benefit from a calibration “below black.” CRT direct view televisions tend to loose dark detail when viewed in brightly-lit rooms.

Historically, gamma adjustment has matched the grayscale of a video camera to the general transfer characteristics of CRTs. Sony’s Graphical Gamma Adjustment matches the grayscale performance of the player to the specific transfer characteristics of your display. Used with a commercially available calibration disc, the Graphical Gamma Adjustment can achieve ideal reproduction.

The system enables you to make adjustments to gamma much like a graphic equalizer adjusts audio frequency response. 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” state by selecting “RESET” on the on-screen display.
