Precision Cinema Progressive™ circuitry (all models)
The purpose of today's high-end home theater systems is to recreate the
look and sound of the movie theater. This includes the vivid detail and seamless
coherence of the film frame. A crucial technology for achieving this goal is DVD-
Video playback with progressive scanning, "480P" output. This works with the
many of today's "HD capable" and "HD monitor" televisions, which offer 480P
inputs. For example, Sony markets this capability as the Hi-Scan 1080i™
chassis. In this context, 480P outputs have been promoted as a must-have
feature in high-end DVD players. However, there continue to be important
differences in how DVD players generate the 480P signal. The DVP-NS999ES
was the first to incorporate Sony's Precision Cinema Progressive system, a
comprehensive approach that incorporates two significant circuits to deliver a
picture that comes closer than ever to the original movie theater experience.
• Pixel-by-Pixel Active interlace-to-progressive (I/P) conversion
• Vertical Edge Compensation
Pixel-by-Pixel Active I/P Conversion (all models)
Interlace-to-Progressive (I/P) conversion is a potentially tricky process.
Simplistic solutions like "frame memory" can end up creating motion artifacts that
mar the final result. These appear as zipper-like patterns on the left and right
edges of moving objects. (See Appendix A for the full story.) Players with "3-2
reverse conversion" overcome this limitation, maintaining the integrity of the
original film frames.
But extracting the full potential of the DVD-Video format requires even
more. Different types of DVD material require different types of conversion. An
I/P conversion strategy optimized for material originally shot on film will not get
the best results for material originally shot on video, and vice versa.
