worldwide Standard Definition and High Definition baseband inputs and performs
advanced video processing to enable the best viewing experience on any
flat-panel display.
VDP-7500 utilizes LSI Logic's industry-leading ClearView
TM
technology to provide
optimum picture quality and innovative features enabling manufacturers to differentiate
their products.
ClearView technology combines state-of-the-art proprietary Pixel Enhancement,
3D Motion Adaptive Deinterlacing with Jaggie Edge Reduction, Advanced 3D Noise
Reduction including built-in Digital 3D Comb filter for NTSC and PAL modes - all
of which work together to produce a superior picture. VDP-7500 architecture also
integrates many other display display processing functions such as up/down scaling,
PIP/POP, contrast/color enhancements and edge enhancements making it one of the most
feature-rich yet cost-effective display processing solutions available in the market today.

Watching noisy video or improperly scaled and deinter-
laced video can ruin the viewing experience especially on
larger displays where every artifact is magnified. LSI Logic's
industry-leading ClearView technology provides a powerful
combination of digital 3D comb filtering for NTSC/PAL,
advanced motion-adaptive 3D deinterlacing, 3D Noise
Reduction and Pixel Enhancement to produce a visually
superior picture on almost any flat panel display.
ClearView Super3D Comb Filter
The 3D adaptive digital temporal comb filter provides
reduction of cross color and cross luma interference resulting
from combining the Y(luma) and C(Chroma) in NTSC/PAL
composite signals. Having this built-in eliminates the need for
an expensive external 3D Comb filter in many cases thereby
saving cost. It also provides significant improvement in the
quality of S-Video input signals where the orginal source
contained YC interference noise (something which external
3D Comb solutions don't handle)
ClearView Deinterlacing
3D Motion Adaptive Video Deinterlacer
The ClearView 3D Motion Adaptive Deinterlacer uses motion
detection and sophisticated 3D Interpolation and 3D Jaggie
Edge Reduction techniques to reduce artifacts and jagged
edges during the deinterlacing process, resulting in a much
more appealing picture. It is a software-programmable
engine that easily allows fine-tuning the picture quality
based on panel characteristics.
Advanced Film Mode Recovery with Pattern Breakdown
Detection and Correction
The built-in Auto Film Mode detection ensures proper
recognition and handling of a 3:2 (NTSC) or 2:2 (PAL) pull
down sequence in TV-adapted film material during the dein-
terlacing process. It uses pattern recognition to reconstruct the
original progressive frames rather than interpolate the missing
pixels. It also detects and corrects a breakdown in the pull-
down pattern or fields mismatched during the editing process,
which would normally result in undesirable artifacts in the
final displayed output.
ClearView Noise Reduction
3D Motion Adaptive Noise Reduction
The 3D Noise Reduction Engine reduces random noise
in the picture by using pixel-level motion detection algorithms.
This results in a much cleaner image especially in the case
of high noise still images.
ClearView Pixel Enhancement
ClearView Pixel Enhancement technology provides yet
another level of picture quality improvement. Its proprietary
text edge detection and smoothing algorithm results in clearer
character boundaries and is a key differentiating feature
for LCD/Plasma panel manufacturers. When applying the
enhancements to images, the picture becomes brilliant and
live even on lower-resolution display panels.

Superior Scaling Engine
The scaling engine in the VDP-7500 processor is an
independent horizontal and vertical scaler capable of 4
segment non-linear horizontal scaling. It supports high-quality
up/down scaling, frame rate up/down conversion, 4:3/16:9
aspect ratio conversion and an independent PIP scaling engine
to allow maximum flexibility.
On Screen Display (OSD)
The on-chip OSD is a powerful and unique font-based
image processing engine supporting a 2 layer OSD. Creating
OSD type images using a font mode as opposed to the more
common graphics mode requires much less display memory
and places less burden on the system processor. This enables
support for multiple display pages with very fast page updates.
The OSD engine is also equipped with all the necessary
functions to support Closed Captioning (CC) and V-Chip.
Key features of the OSD engine:
Bit-mapped OSD
Font table supports up to 256 fonts
Programmable display rows and columns, up to 1K display
characters
Programmable character cell resolution, up to 32 pixels x
64 pixels
Programmable horizontal and vertical display position
Uses up to 32 entries true color palette table to program
foreground and background colors of characters
Provides 8 separate
levels of alpha
blending for foreground
and background
PIP/POP
The easy-to-program on-chip Picture-in-Picture (PIP) and
Picture-on-Picture (POP) engine can support simultaneous
display of up to 9/16 PIP windows. It supports fast page
switching and includes the following programmable features:
"Split-screen" mode, POP display, one selectable PIP window
for highlight, "Zoom-in" window for user to zoom the main
screen, PIP window in PC mode, and deinterlace mode in PIP
display image.
Flexible I/O
The processor provides very flexible system configuration
for connecting multiple devices on the system board without
glue logic as shown in the Reference Design Block Diagram
(figure 1). It has independent inputs for the main picture and
PIP allowing the PIP to display an independent video input from
what the main screen is displaying. Its progressive output port
supports a glueless interface to most common DAC devices
for analog output and LVDS/DVI panel transmitters.
VDP-7500 is also designed to support advanced
computer displays. Some of the key embedded functions
include input windowing adjustment, auto window-size
detection, auto clock-phase adjustment and input timing-mode
detection to meet the demanding requirements of today's
computer display systems.
External CPU Interface
Since most of the complicated and time-critical functions
are implemented using register-level programmable engines
within the processor, VDP-7500 can be easily programmed
using a low-cost 8051-like micro controller. Having the CPU
external also allows for added system design flexibility.

Example of simultaneous display of 9 independent
PIP windows.
