Integrated Digital
Terrestrial Receiver
The integrated digital terrestrial receiver is all
you need to enjoy full access to ATSC digital
terrestrial broadcasts, all the way from
standard definition (SD) to 1080i high
definition. Since the digital terrestrial receiver
is built in, you do not need an IEEE 1394
connection and an extra STB (for ATSC
broadcasts). The HM-DT100 receives all
forms of ATSC digital terrestrial programs
including high-definition broadcasts, records
them exactly “as they are” with no loss of
quality, and plays them back whenever you
want.
Single, Uncompressed,
Digital HDMI™
Connection with
Content Protection
(HDCP) Technology
Adopted by over 100
manufacturers, the digital
HDMI™ interface is already set to become
the standard of the future. It delivers
uncompressed digital video and audio signals
to your display, so there is no signal
deterioration. HDMI™ prevents any signal
loss by transferring video digitally, without
going through an analog interface or
performing unnecessary digital-to-analog
conversions, delivering a pristine signal that
produces lossless images identical to the
original. Not only does HDMI™ give you the
highest quality images, but also true-to-life
sound to intensify your home theater
experience.
Backed by major motion picture studios,
HDMI™ provides digital content that truly
reflects the filmmaker’s original vision. To
support secure one-way transfer of digital
content, the HM-DT100 and HM-DH5 feature
HDMI™ output with content protection
technology called HDCP.
Plus, HDMI™ also transfers video from
existing standard definition analog sources,
after conversion to progressive 480p digital
video for greatly improved image quality. And,
since this breakthrough technology’s single
cable handles both video and multi-channel
audio, it makes cabling complications a thing
of the past.
* Copy protected contents cannot be transferred through the
HDMI™ output to any device not equipped with an HDCP-
compliant connector. Please be sure to connect to or via
HDCP-compliant devices.
** HDMI™ is compatible with DVI-D so an HDMI™ cable can
be connected to a DVI-D-compatible TV display using a
DVI conversion cable. However, please be sure to verify
that the source unit is HDCP-compliant.
*** The DVI-D cable does not carry audio signals.
HDTV Compatible MPEG-2 HD Decoder
and HDTV Component Output
In addition to HDMI™ digital-to-digital
connection, the HM-DT100 and HM-DH5
also support analog connection. The
MPEG-2 HD Decoder converts recorded
MPEG-2 signals into Component output
signals (Y/Pb/Pr). Connect directly to any
HDTV or projector equipped with Component
input terminals to enjoy the full quality of
D-Theater™ software and other high-
definition images.
MPEG-2 CODEC to Record Various
Sources Digitally
The standard definition MPEG-2 encoder
makes D-VHS digital recordings from NTSC
analog sources, as well as converting signals
from a connected MiniDV camcorder to
MPEG-2 and recording them on D-VHS.
Super MPEG Encode Pre-Processor
Enhances Analog Signals for Digital
Recording
To record analog sources in high-quality
digital, the HM-DT100 and HM-DH5 use
JVC’s exclusive Super MPEG Encode Pre-
Processor to eliminate the defects inherent in
analog signals and create new digital
recordings that actually appear to surpass the
original quality. Its Time Base Corrector (TBC)
eliminates jitter, Frame Synchronizer corrects
frame crossover jitter and processes any
deviant frames, and Motion Active Noise
Reduction circuit removes noise from both
still and moving parts of video pictures. The
decks digitally encode and record the now
pristine NTSC-compliant analog input signals,
free of image lag, smear and MPEG artifacts
such as mosquito noise.
5.1ch Dolby Digital Sound
The D-VHS decks record high-
definition broadcasts complete with 5.1ch
surround sound. In addition, HDMI™ and the
optical digital audio output make it easy to
connect and enjoy outstanding audio
performance on your home theater sound
system.
Linear PCM Digital Audio Capability
Thanks to the HM-DT100 and HM-DH5’s
48kHz/16-bit linear PCM recording in either
HS or STD mode, you can record full quality
linear PCM digital sound from a MiniDV
camcorder connected via i.LINK. You can
also record high-quality soundtracks from
analog sources in this non-compressed
digital format to accompany the resulting
high-quality digital image. The PCM audio
data rate uses 1.6 Mbps out of the
28.2 Mbps HS and 14.1 Mbps STD modes.
i.LINK Terminals
IEEE 1394 (i.LINK) digital interface
terminals with DTCP* content protection
technology on the front and rear of the
HM-DT100 and HM-DH5 allow you to easily
connect with i.LINK compatible devices such
as a MiniDV or high-definition camcorders for
convenient digital-to-digital dubbing. You can
also connect the HM-DH5 with a Digital
Set-Top Box (STB) to transfer and record HD
and SD broadcast digital signals**.
* DTCP (Digital Transmission Content Protection) protects
digital content from unauthorized copying. Copy-protected
contents cannot be recorded via i.LINK terminals.
Connected digital devices must be DTCP-compatible to
playback copy-protected digital content.
** Service depends on whether the digital stream provided
by cable systems conforms to the ATSC format.
Full Spec HDTV Compatible
When it comes to HDTV recording, nothing
compares to JVC’s D-VHS. With a
28.2 Mbps HS mode that exceeds the
19 Mbps specification of ATSC MPEG-2 HD
broadcasting formats, D-VHS captures the
full HDTV signal with no data loss
whatsoever. And since a single D-VHS
