Introducing JVC ProHD
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

ProHD —
Concept of
JVC’s Affordable HD
Solution
1. HDV Full Progressive Scanning (720p)
Industry leading professionals told us that they wanted a
progressive scanning system that would shoot and record the
highest quality continuous moving images. ProHD uses the 720
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 HL-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 systems. Direct
digital transfers through 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
expression on the big screen, 24 frame progressive recordings
can be transferred easily to 16 mm or 35 mm film.

Advantages of ProHD
1.HDV format
HDV is a video format
designed to enable the
recording of high definition
MPEG-2 video on standard
DV media (DV or MiniDV
cassette tape). The HDV
format was defined by four companies: Canon Inc., Sharp
Corporation, Sony Corporation, and Victor Company of Japan,
Limited (JVC). The specification of
the HDV format incorporates two
versions, one progressive (720p)
and the other interlaced
(1080i). HDV uses the same
track pitch and tape speed as
the DV format, and therefore
the recording times are the
same length as the DV
format.
2.HD Progressive
(720p) format for
high quality moving
pictures and digital stills
played in slow motion, each individual frame contains the full
detail of the original image — excellent for viewing and
analysing motion. Stills and prints captured from HD
progressive video look far better than from interlaced video. In
any case, today’s flat panel television displays and fixed matrix
projectors, such as D-ILA, DLP and LCD, are all native
progressive scanning systems. This means that JVC’s
progressive HDV recordings can be displayed without
imperfection, because they do not need to pass through the
degenerative process of de-interlacing, prior to being
displayed.
Progressive scanning
The new ProHD products use the same progressive
scanning system as used in all high-end HDTV cameras.
Progressive scanning systems uniquely
capture and store full frames of image
information. It is a very simple process to
convert a progressive signal to
interlaced, but not vice versa. When
progressive recordings are frozen or
Multi-format output (BR-HD50)
Progressively scanned pictures are converted easily to the
interlaced format by extracting the odd lines from progressive
frame 1 and the even lines from progressive frame 2 to create
the two fields required for each interlaced frame. Not only
does the BR-HD50 output its native 720p, but also its built-in
scan converter can generate 1080i and standard definition
signals. Converting the other way, to progressive from interlaced,
presents a much greater technical challenge, requiring both
hardware and motion analysis software to achieve
satisfactory results.
Blu-ray and HD-DVD compatible
The IEEE 1394 connector provides a digital
output for editing & recording and for direct
transfer to the new generation DVD formats
(Blu-ray and HD-DVD). ProHD camcorders and
recorders, with their native MPEG-2 TS
(Transport Stream), provide a recording signal
which is easily transferred to these new DVD
formats. This ensures no loss of picture quality.
3●
HDV and DV compatibility
The HDV format uses the same recording track pitch (10 µm)
as Professional DV, meaning that ProHD also offers track pitch
compatibility with the DV format and the same recording time.
This remarkable HD recording capability was achieved by
developing a new high-power MPEG codec system capable of
maintaining high-definition picture quality, whilst compressing
the data to 19.7 Mbps bit rate. With its superior resolution and
advanced processing, ProHD delivers top performance in both
its native 16:9 HD mode and in the SD mode. The facility to
make recordings in either HD or SD makes ProHD the ideal
choice for professionals not quite ready to make the full
transition to HD.
Progressive HDV-compatible support
To maximise picture quality and performance from input to
output, JVC employs the HDV 720 progressive system.
Progressive HDV’s resolution of 1280 x 720 is the same as
the native resolution of most HD display devices in use
today (LCD, plasma, DLP, D-ILA). HDV
720p is thus natively compatible in
terms of both resolution and
scanning system with the vast
majority of today’s HD displays.
3.Real 24p
24p Progressive Full HD images are ideal for cinematographic
applications. From shooting to editing and distribution, an HD
system can be established for film-like productions. Unlike 24p
images in standard definition, when real 24p HD video is
down-converted to SD, the result is truly film-like DVDs. The
camcorder itself, with its video lens removed and replaced by a
film lens converter system, such as the Mini 35 from P & S
Technik, effectively becomes a digital film camera.
4.JVC’s dual recording system
The optional JVC Hard Disk Recorder DR-HD100 creates a
dual recording system of tape and hard disk. This system is
already utilised by Professional DV users the world over. The
many advantages inherent in JVC’s dual recording system of
tape & hard disk drive are well appreciated. It was only natural
that JVC’s range of ProHD models would include a
Hard Disk Drive recorder and one that can operate
equally in DV and HDV modes. The dual recording
system provides fast and efficient HDD-based
editing and cost-effective archiving, using low-cost
tapes. Thanks to the newly developed MPEG-2
encoding IC, high-quality pictures can be
recorded on readily available compact DV
cassettes, so running costs are minimal. As no
special equipment or exclusive media are
required, the operating costs of the total system
can be kept low. The DR-HD100 is mounted
at the rear of the camcorder, utilising an
optional bracket which is provided by the leading
battery systems manufacturers.
The GY-HD110, fitted with Mini 35 film adapter from P & S Technik, becomes a digital film camera.

The compact size and wealth
of professional features of the
GY-HD110 apply just as much
to the SD user as to those
working in High Definition.
Existing DV equipment and
accessories can continue to
be used with the GY-HD110.
However its three CCDs with
1280 x 720 pixel resolution
ensure high quality images
with superb colourimetry in
both widescreen 16:9 modes
and also in a standard 4:3
aspect ratio.
For those upgrading in the
future to High Definition, the
GY-HD110 will provide a
seamless link from the
Standard Definition formats
currently in use to those
in demand for the coming
HD standards.
Signal: 576i digital component throughout.
Application: Integration with existing
SD editing equipment plus
additional facility for true
native 16:9 origination.
From the native uncompressed
720p signal, the GY-HD110
camcorder can be set to
generate the HDVô compliant
720p 24 recording signal which
can record to cassette or to
hard disk recorder. The
recordings can then be fed in
and out of an appropriate NLE
and so to a film laser printer,
without any requirement for
cross-conversion, either from
25p by way of 4% speed
change or from 30p by process
of 3:2 pull-down.
A further advantage of the
GY-HD110 for film schools is
that accessories allow the
camcorder to be transformed
into a digital film camera. The
PL-mount adaptor allows prime
film lenses to be deployed and
also a matte box. Since the
optional add-on DR-HD100
hard disk recorder will also
record the HDVô for mat of
720p 24, many hours at a time
can be put ìin the canî.
For the film shooting
application of ìvideo assistî,
even standard definition
recording can be set to 24p
progressive to capture perfectly
the film effect.
Signal: 720p 24.
Application: Acquisition for cinematography,
transfer to film & video assist.
The diagram shows the video
signals that are commonly found
in HD and SD production in
Europe. Specifically this diagram
illustrates how these signals are
directly available from either the
GY-HD110 or the BR-HD50 via
a tape recorded in the native
720p 30/25 format on either of
these devices.
This flexibility comes in part as
a result of the original material
being recorded in a progressive
format, which allows for easier
and more effective conversion
to other formats than if the
original had been recorded as
an interlaced signal.
Signal: 720p 60/50, 720p 30/25, 1080i 60/50,
and 576i 50.
Application: Various, where material is
to be matched with existing
footage or images captured
on another format.
