The
Digital Hi-Def camcorder records in both NTSC and U.S. ATSC HDTV standard
video on a standard Mini DV cassette. Recording can be done in 4:3 480i
(DV compression) as well as 16:9 480/60p and 16:9 720/30p (MPEG-2
compression). In analog component it plays back in 480i (NTSC) and
480/60p, 720/60p, 1080i (ATSC), making it compatible with virtually all
display devices. Its digital i.LINK outputs IEEE 1394-compliant 480i
(NTSC) and 480/60p, 720/30p (ATSC) to D-VHS or computers via the FireWire
connection.
To maximize its application potential in
the field, and assure seamless transfer to a variety of post-production
environments, the camcorder is equipped with three ATSC compatible
shooting modes:
HD Mode that records 720/30p digital high-definition images,
SD Mode for 525p progressive wide images, and
DV Mode which records at conventional NTSC 480i DV standard.
High efficiency 6 frame group of pictures (GOP) Hi-Def MPEG compression
allows the same recording time for HD on Mini DV cassettes as for standard
SD DV compression.

Hybrid
Complementary Primary Digital Filter
Hi-Def color purity and discrete reproduction allows you to see full
detail without being obscured by lowresolution color smearing. The Hi-Def
standard colorimetric range takes in more colors than NTSC as well. |

HD
Generation
With the advent of digital broadcasting, the industry is evolving at a
rapid pace. With those changes also come real digital improvements for
both viewing and recording. Now, with JVC's digital hi-def camcorder, you
can own and shoot with a thoroughly up-to-date digital camcorder, record
and edit hi-def images on their own PC that will stand the test of time,
and view and share their personal digital movies on HD D-VHS or DVDs via a
wide variety of display devices. All this innovation is made possible
using standard Mini DV cassettes. |

Resolution
What matters is that this camcorder lets you record, preserve and playback
high quality 700/650 Horizontal/Vertical lines of resolution (close to the
achievable limit of the format) component Hi-Def video in a reasonable
price range. |

Hi-Def
MPEG-2 on MiniDV Cassette
Another remarkable aspect of this video camera is that it records 60
minutes of HD signals on conventional MiniDV cassette. The benefit is
obvious: MiniDV format, the defacto standard, is widely available and
affordable compared to other formats used in professional systems, and by
using a common cassette mechanism with DV, it is possible for the
camcorder to offer regular DV recording as well. |

Digital
MPEG-2 Hi-Def and SD Recording
While the picture is encoded one frame at a time for DV, the time axis is
encoded as well for MPEG-2, conforming to the HD Digital VCR
Conferences Part 7 (DVB) and Part 8 (ATV) standards. The GR-HD1 uses
a GOP (Group Of Pictures) of 6 for HD and 12 for SD, with a frame order of
IBBPBB. The I frame is a complete frame without reference to any past or
future frames; the P frame is encoded relative to the past reference
frame; and the B frame is encoded relative to the past reference frame,
future reference frame, or both.
I Picture Intra Coded Picture.
B Picture Bi-directionally Predictive Coded Picture.
P Picture Predictive Picture. |

High
Speed Search Playback Possible
The i frame can be played back without using any other frame and is
recorded in the appropriate variable speed playback area on the tape,
allowing high-speed search during playback. |

Recording
and Playback of Digital HD Images
The Hi-Def Camcorder is able to record and play back 1280x720/30p digital
high definition and 480p progressive wide images using a Mini DV tape.
Important factors in making this possible are a newly developed 1/3-inch
1.18 million pixel progressive scan CCD and JVC proprietary signal
processing. |

Images
Can Be Enjoyed On Virtually Any Monitor
Converts 720/30p digital HD images and 480p progressive wide images to the
1080i high-definition standard for viewing on the latest HD display
devices. The down-converter converts images to conventional NTSC 480i
broadcast standard video, enabling images to be enjoyed on virtually any
TV. |
| • |
CCD
Incorporates a newly developed single 1/3-inch 1.18 million pixel (1.14
million effective pixels) progressive scan CCD with patented progressive
color filtering, as well as JVC's original signal processing circuitry and
driving system. All together, this constitutes a system finely tuned to
gathering high-resolution, high quality images. |

Full
Digital Interfaces
The camcorder is excellent at getting the images and sounds you need to
the location where you need them.
Live HD images at 720/30p can be monitored digitally via the i.LINK
connector (IEEE 1394) is primarily for transfer of MPEG-2 and DV video
data to and from a PC or other compatible device like a D-VHS VCR.
(Dubbing is not possible from analog HD sources). You get lossless digital
dubbing of both pictures and sound in one cable.
USB for transfer of digital still images to and from a PC.
SD or MMC Memory Card for storage of digital stills and transfer of data
to PC with appropriate slot or external reader.
Web-Camera Function Communicate via web-camera by running third party
applications such as Windows Messenger for teleconferencing, video
phoning, webcasting or surveillance. |

HD
and SD mode MPEG-1
Record wide dynamic range 48kHz digital audio with the camera's stereo
microphone or via external stereo mini plug mic input. HD and SD modes
record at 384 kbps. DV mode also records in 2 channel 48kHz or the 32 kHz
4 channel mode for post audio dubbing. Wind cut mode helps cut down wind
created noise. |

Zoom
High quality 10x optical zoom lens with low distortion and high color
purity edge to edge and across the entire zoom range, with light gathering
ability that varies between just f1.8 and f1.9. |
| • |
Stable
Images
Its built-in optical image stabilizer provides ample zooming capability
coupled with the non-degrading image stabilization of an optical system. |
| • |
Rotating
Grip for Stable Shooting
The camera's grip section rotates by up to 90 degrees, with smooth,
uninterrupted motion from high-to-low-angle to allow stable shooting at
all times. All the while the operator's hand remains on the grip, with
fingertip control of zoom and auto/manual focus rings, auto/manual white
balance, auto/manual exposure and shutter speed features. |
| • |
LCD
Monitor
With the rotating 3.5" high-resolution 2 Megapixel LCD monitor, you
can shoot at angles and positions where the viewfinder isn't comfortable
or practical. The LCD monitor can be viewed simultaneously with the
viewfinder including comprehensive menu and camera condition information,
especially convenient when working with others. |
| • |
Color
Viewfinder
Viewfinder incorporates 113,000 pixels, providing a clear full color view
of video subjects. |
| • |
Power
Linked Operation
By pulling out the viewfinder or opening the LCD monitor the camcorder
automatically powers up so you're ready to shoot.
When closing - power automatically shuts off to save energy. |
| • |
Card
Slot
Expands video possibilities with a built-in slot for an SD (Secure
Digital) Memory Card or a MultiMediaCard, in addition to the MiniDV
cassette. With this camcorder easily transfer images to your PC directly
from the camcorders IEEE-1394 jack. |

Tally
Lamp, Beep or Melody
If needed, beep or melody sounds signify power-on and recording signaled
by the tally lamp as well as a beep or melody. A shutter sound can
indicate still shooting. |
| • |
DV
Mode 16:9 Anamorphic Wide
In DV mode, 16:9 Squeeze wide uses a wider view of the CCD (941 x 483
pixels) to create a full 16:9 image. This is then fit into the regular 4:3
NTSC signal to make a natural electrical anamorphic squeezed image to play
back on a 16:9 TV at 60i. |
| • |
DV
Mode 4:3 Digital Wide
Digital Wide's broader pixel area (941 x 646) generates a high resolution
wide-angle image equivalent to a 0.7x wide conversion lens. The frame rate
is 30fps output on 60i, with increased sensitivity. |
