— defining
the future of
professional video

With the introduction of JVC’s ProHD, the promise of digital
technology has finally been fulfilled. Surprisingly affordable,
impressively professional, and remarkably compact, ProHD
embraces the HDV format to deliver a complete high-definition
solution that has been designed to meet the needs of today’s
most demanding professionals, while retaining the ability to
adapt to future requirements.

Since the launch of D9 in 1996 and Professional DV in 1999, JVC
has continued to develop and diversify its digital video offerings
in response to the rapidly changing environment of visual
communications and production. JVC continues to evolve its
digital cameras and recorders with advanced features and
varied storage options, including full-size DV tape and Hard Disk
Drives.

Now with the production and delivery of video content starting
to shift to high definition, JVC has combined its expertise in
camera, encoding and storage technologies to create an
affordable HD solution. JVC’s ProHD system,
adopting the HDV format, utilises widely available
non-proprietary technologies such as MPEG-2
compression, DV recording media
and conventional hard disk drives.
Based on input from leading end users,
JVC has developed a system with
the most sought-after professional features
and performance. Noteworthy ProHD features
include full HD progressive
scanning, real 24p,
and a dual recording
system using tape
& HDD. As ProHD
evolves, it will include
optical and solid state
recording media.
Designed and built for
professionals, ProHD is
the fulfillment of the digital
promise, offering true high
definition performance in
a compact, affordable system.

The latest addition to the ProHD
system, the GY-HD200/GY-HD201
is a compact shoulder-mount
camcorder featuring full-frame
50p recording for smooth,
continuous images.

— JVC’s Affordable
HD Solution

1. HDV Full Progressive Scanning (720p)

Leading industry professionals told us that they wanted a full­frame progressive scanning system that would shoot and
record the highest quality continuous moving images. ProHD
uses the 720/50p progressive HDV format and produces crisp,
native HD images which perfectly match today’s digital
displays and which can be converted easily, without
degradation, to interlaced scanning pictures.

2. Time Code

As a professional system, ProHD products include the facility
to record and display timecode. Convenient menu operation
makes it easy to preset time code at the beginning of a tape.
Simply select REC RUN or re-generation mode. User bits are
also available.

3. Highly efficient video compression

To provide the highest quality HD recording, JVC uses the
broadcast industry standard MPEG-2 Main Profile at H-14.
Offering far greater efficiency than frame-bound systems,
ProHD records at data rates at or above commercial broadcast
rates. Recent advancements in non-linear editing have made it
possible to edit ProHD on virtually all popular non-linear
editing systems. Direct digital transfers via IEEE 1394 ensure
the quality is maintained throughout the transfer process.

4. Dual recording system

Designed to utilise both DV tape and hard disk drives, ProHD
offers the ultimate in media versatility, maximising productivity
with efficient, economical editing and low-cost archiving. Now
you can safely archive the original tape cassette and then plug
the hard disk straight into your NLE. Editing can start right
away — no need to make dubs or transfer data.

5. Real 24p

With ProHD, the dream of creating HD video with the essence
of film has at last been realised. By capturing and recording at
the film frame rate of 24fps, and offering extensive user
configurable settings such as exposure, gamma and detail,
ProHD becomes an important tool for creative expression. For
the ultimate form of display on the cinema screen, 24 frame
progressive recordings can be readily transferred to 16 mm or
35 mm film.
