Important Safety Instructions
Please read all instructions and precautions carefully and completely before operating your Proceed Progressive
Video Processor.
1. ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting
any cables, or when cleaning any component.
2. The product into which the PVP is installed is equipped with a three-conductor AC mains power
cord which includes an earth ground connection. To prevent shock hazard, all three connections
must ALWAYS be used. If your electrical outlets will not accept this type of plug, an adapter may
be purchased. If an adapter is necessary, be sure it is an approved type and is used properly, supplying an earth ground. If you are not sure of the integrity of your home electrical system, contact
a licensed electrician for assistance.
3. AC extension cords are not recommended for use with this product. If an extension cord must be
used, be sure it is an approved type and has sufficient current-carrying capacity to power this
product.
4. NEVER use flammable or combustible chemicals for cleaning audio components.
5. NEVER operate this product with any covers removed.
6. NEVER wet the inside of this product with any liquid.
7. NEVER pour or spill liquids directly onto this unit.
8. NEVER block air flow through ventilation slots or heatsinks.
9. NEVER bypass any fuse.
10. NEVER replace any fuse with a value or type other than those specified.
11. NEVER attempt to repair this product. If a problem occurs, contact your Proceed
12. NEVER expose this product to extremely high or low temperatures.
13. NEVER operate this product in an explosive atmosphere.
14. ALWAYS keep electrical equipment out of the reach of children.
15. ALWAYS unplug sensitive electronic equipment during lightning storms.

Unpacking and Preparation
Unpacking the PVP Unpack your PVP Progressive Video Processor from the carton.
The carton includes:
• a video input board (in an electrostatically protected bag)
• a progressive video output board (also in an electrostatically protected bag)
Important! Do not open the plastic bags in which your PVP circuit boards
are shipped!
These are specially designed to protect the sensitive circuitry
on the boards from ESD (ElectroStatic Discharges) that can
easily destroy modern electronics.
They should be opened only by a qualified and properly
grounded service technician, when installing the circuit
boards inside a PMDT.

Installing the PVP The PVP may be installed only into a Proceed PMDT modular DVD transport,
and must be done by an authorized Proceed dealer or service center. While
simple to do, proper ESD (ElectroStatic Discharge) precautions must be observed
to prevent damage to the circuitry being installed as well as that already within
the PMDT.
• All work should be performed in a clean, well-lit area.
• All work should be performed on anti-static surfaces.
• The technician doing the installation should wear a properlygrounded anti-static strap at all tims during the installation.
Voltage label
Operating Voltage & Frequency
The PMDT is set at the factory (internally) for 100V, 120V, 200V, 220V, or 240V AC
mains operation as appropriate for the country in which it is to be sold. (230V/
50Hz only in European Union countries, in compliance with CE regulations.)
Make sure that the label on the rear panel of the PMDT (beside the AC input receptacle) indicates the correct AC operating voltage for your location. Attempting
to operate the PMDT at an incorrect voltage can damage the unit.
The PMDT Modular DVD Transport is also set at the factory for operation on either 50 or 60 Hz AC line frequencies, as appropriate for the country in which it is
to be sold. It will not operate if it senses an incorrect line frequency.
Neither the voltage nor the line frequency setting may be changed by the user.

If the AC mains voltage or frequency indicated on your PMDT is incorrect, please
contact your local, authorized Proceed dealer or distributor.
The PMDT can easily be powered by a normal 15-ampere AC mains line. If other
devices are also powered from the same AC line, their additional power consumption should be taken into account.

Special Design Features
Digital television (DTV) has given us greatly improved pictures and sound with
which we may entertain ourselves. However, most of us still have significant legacies of existing videos and programs we like to watch that have not yet benefitted
from the performance advantages DTV offers. The PVP fills that gap by converting normal, “interlaced” video to 480p “progressive” video, a DTV standard.
But with new technology inevitably comes new terminology. A brief introduction
to the new jargon is probably in order.
Deinterlacing (“Line Doubling”) Many people mistakenly assume that a line doubler “doubles” the number of
lines in the video signal, perhaps through some sort of interpolation. Given the
name, this is a reasonable assumption. Unfortunately, it happens to be wrong.
A better name for a line doubler would be a “deinterlacer” or perhaps a “line accumulator.” The main task of a line doubler is to buffer up the odd and even
lines, reassembling them in the correct order.
Simple (read “cheap”) line doublers do just that. They put all the first field (the
odd numbered lines of information) into memory, then the second field (all the
even numbered lines), and then “reshuffle the deck” to put them back into sequential, progressive order. Having done so, they pass along the entire frame to
the video display. In fact, they do so twice: once for the time that each field
8
would otherwise have been displayed, so as to avoid flicker. This is precisely what
the unsophisticated progressive outputs built into MPEG decoder chips do.
Thus a line doubler reads out entire frames of information as often as individual
fields are normally displayed. (This is where the misleading name comes from.)
Since you are now displaying twice as much information in each unit of time, the
TV has to work faster to keep up. Specifically, normal NTSC uses a “horizontal
rate” of about 15.75 kHz. This means that the electron beam in a CRT is turning
on and off 15,750 times per second (roughly).
To display a line doubled signal, it must turn on and off twice as fast to display
all those extra pixels: about 31.5 kHz. “Regular” televisions cannot do this—this is
one of the things you pay extra for with DTV designs.
Problem: what if the interlaced camera used to shoot the video in the first place
was pointed at something that was moving? During fast action, the subject would
have moved between one field and the next. If you simply reassemble field into
frame in a simplistic way, you get jagged edges of moving objects because the
fields don’t line up. This is where motion compensation comes in. It uses sophisticated analysis to compensate for such problems, ensuring that objects stay together despite the motion between one field and the next. Good line doublers
handle this sort of thing much better than simple ones do.
Another problem: video today comes from a variety of sources, including:
• film at 24 frames per second, progressively scanned during conversion to video ;
• video cameras, running at an interlaced 30 frames per second;
