Advanced Digital Direct Pixel Drive with VQE9 —
™
All-Digital 10-bit Signal Processing and Transmission
with HDMI (DV-79AVi)
The DV-79AVi Elite DVD player features an upgraded version of
™
the Pioneer-trademark Digital Direct Pixel Drive . If you
connect the player with a compatible A/V receiver or plasma
display panel via the HDMI terminal, the advanced technology
allows all-digital signal processing and transmission — with high
10-bit precision thanks to the "VQE9" video-encoding LSI.
Because the signals remain digital, they are free from conversion
loss, delivering pictures with less noise and finer details than those
with analog conversion. The player also converts up pixels for
HDMI output. (See the figure at the bottom of the page.)
VQE9 Video-Encoding LSI
The Advanced Digital Direct Pixel
Drive features VQE9 video-encoding
™
LSI. This state-of-the-art device allows
expansion to 10 bits, and all the processes
for improving picture quality are
performed on a single chip, including:
• Effective noise reduction with Component Frame DNR Pro
(see page 23 for details)
• Highly-precise motion detection for more natural textures and
smoother edges of moving images from video sources
• A wide variety of picture adjustment options
• High-resolution progressive pictures (PureCinema

which up-converts traditional DVD video signals to high-
definition resolution in the most appropriate way for the
connected monitor or TV. When the Elite DVD player is
connected to a DLP projector with 1280 x 720 pixels, for
example, the pixel conversion IC up-converts the progressive
720 x 480 signals to progressive 1280 x 720 signals which
exactly fit the pixel count of the projector. The signals
generated by the MPEG decoder pass through the Two-
Dimensional Resolution Expander, and then are output via
HDMI to an HDMI-compatible monitor or TV.
108 MHz/14-bit Video D/A Converter (DV-79AVi)
When video signals are output to non-HDMI devices, the Elite
DVD player uses the high-grade 108 MHz/14-bit video D/A
converter. Combining 8x oversampling with high 14-bit
precision, this premium device ensures superior linearity by
preventing phase fluctuations. The converter also controls
overshoot and undershoot without affecting the original signals,
even when the picture has high contrast.

Technology (DV-79AVi/DV-46AV)
Interlaced vs. Progressive Scanning
• Interlaced scan system — NTSC TV Standard
When you look at your TV screen close up, you will notice an
image is made up of many horizontal lines. These are called scan
lines: an image is painted on the screen by the scan lines that
sweep from left to right, and top to bottom, in sequence. One
screenful of TV picture is equivalent to a frame; by current NTSC
TV standards there are 480 scan lines in each frame (480i).
All 480 scan lines that form an image are not sent to
your TV at the same time; every other line is transmitted
alternately every 1/60 second. In other words, in the first 1/60
of a second, odd-numbered lines (1st, 3rd, 5th, and so on),
which total 240 and collectively form an odd-numbered field,
are sent. In the next 1/60 of a second, even-numbered lines
(2nd, 4th, 6th, and so on), which collectively form an even-
number field, are transmitted to fill in the remaining space. In
this way, a complete image, that is, a frame, is formed.
Such is NTSC interlaced scanning. With this system,
lines are scanned for odd- and even-numbered fields alternately
every 1/60 second, to build one frame every 1/30 second.
• Progressive scanning for double resolution of interlaced scanning
With interlaced scanning used by NTSC TV standards, the
larger the display, the more noticeable the picture flicker.
Progressive scanning was developed to solve this problem.
With progressive scanning, all 480 lines are scanned from top to
bottom in 1/60 of a second to build an entire frame (480p).

With a progressive scan TV, the data for the odd- and even-

numbered fields is stored in memory and undergoes field

interpolation to convert from 30fps (frames-per-second) format
to 60fps simulated format. Therefore, progressive scanning can

2-3 Pull-down PureCinema Progressive Scan Technology
Normally there are 24 frames per second (24fps) on film. On
DVD, movies are recorded in the same 24fps format, each
frame containing the data for the entire 480 scanning lines
(480p) for progressive scanning. Pioneer's 2-3 Pull-down
PureCinema Progressive Scan Technology is exactly the
technique to take advantage of delicately nuanced images
recorded by progressive scanning. DVDs hold the data for
inverse telecine conversion: When playing back film-originated
sources, Pioneer's advanced scanning technology makes use of
the data and inserts additional frames accurately. This allows
the viewer to enjoy natural, film-like images. Pictures are
smooth and sharp, with high resolution, free of bothersome
artifacts like jagged edges on moving objects.
Note: With the DV-46AV, PureCinema Progressive Scan directly turns 24fps progres-
sive images from DVDs into 60fps progressive images. Because conventional progres-
sive-interlace-progressive conversion is not used, this represents simpler, more efficient
way of conversion.

Note: To enjoy the advantages of PureCinema Progressive Scan Technology,
your TV must be compatible with D2 or higher component video formats. The
RCA-pin type component video output offers purer colors and finer gradations.
Component Frame DNR (DVD/VCD) PRO (DV-79AVi)
DVD boasts a horizontal video resolution of more than 500
lines. Unfortunately, high resolution brings about a drawback
of its own: minute noise is more visible. So Pioneer developed
component frame cycling DNR (Digital Noise Reduction). It
discriminates noise in each of the three components that
comprise video signals — Y (luminance), P and P . Since it

compares consecutive frames rather than consecutive fields, and
processes individual components rather than composite signals,
DNR provides superb noise reduction capability while retaining
high resolution.
