The mathematical algorithms of Sony's Pixel-by-Pixel Active I/P
conversion have been committed to silicon in this Large Scale
Integrated circuit (LSI), the Sony CXD9866R.
Sony solves the problem with Pixel-by-Pixel Active I/P conversion that
includes built-in motion detection. The system automatically recognizes each
type of material and applies the appropriate processing. This enables us to
generate the ideal progressive scanning output for each type of DVD source.
• Film originated material. For footage originally shot on 24-frames per
second film and 24-frame progressive digital cameras, 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. The Sony® system automatically and flawlessly detects the 3-2
cadence and performs full "3-2 reverse conversion," which maintains the
integrity of the original film frames. Mismatched film frames are never "force-
fit" into a single video frame. The system adds no motion blurring. You'll
enjoy twice the vertical resolution of conventional interlace video, for an
experience that's less like watching television and more like watching film.
• Film originated material on a DVD-R/RW or DVD+R/RW. DVD recorders
complicate the I/P conversion processes, because these recorders capture
everything as interlaced video. That means movies, even if they were
originally shot on film, are recorded as 30 frames per second interlaced, not
24 frames per second progressive. There are none of the usual First Field
Repeat Flags (FFRFs), leaving many DVD players unable to guess at the
original frame structure. In this case, conventional 3-2 reverse conversion will
not work, but Sony's Pixel-by-Pixel Active I/P conversion will. Thanks to built-
in motion detection, the Sony system does not depend on FFRFs. So you get
accurate reproduction on DVD-R/RW and DVD+R/RW discs.
• Film material intercut with video material. Sony's Pixel-by-Pixel Active I/P
conversion applies appropriate processing for film elements and interlaced
video elements, even when they alternate in rapid-fire sequence, as they
might during the "making of" documentary on a movie DVD. The Sony
system instantly recognizes the characteristics and film and video and
automatically applies the correct processing for each.
