Consumer products are
driving the success of the
electronics industry. We’re
seeing prices fall as production
ramps up. Also,
HDTV has pushed the
demand for set-top boxes, satellite
receivers, and HD video players.
HDTV GOES 1080P
Progressive
scan, or 1920 by 1080 pixels (1080p),
is the top end of the HDTV standard.
Now, it’s finally showing up in a
wider range of displays as well as in
content delivery systems such as Bluray
and HD DVD players. However,
many HDTVs being sold only manage
720p or 1080i (interleaved).
Sharp’s Aquos LC-46D64U 46-in. LCD
HDTV represents the best of the market
(Fig. 1). Delivering 1080p quality in a
slim-line design that’s 25% thinner than
prior versions, it uses Sharp’s proprietary
Advanced Super View/Black TFT Panel
with multipixel technology. Its Enhanced
Picture Contrast Technology delivers a
10,000:1 dynamic contrast ratio as well
as a wide 176º viewing angle. The screen’s
4-ms response time displays fast-moving
video without artifacts.
The HDTV has ATSC, QAM, and
NTSC tuners for over-the-air, cable, and
satellite support. There are three HDMI
v1.3 inputs, two HD inputs, a
VGA input, three composite
video inputs, and an S-video
input. A serial port allows PC
remote control. Also, the Aquos’
stunning image quality
matches its sleek cabinet. Like
most large screens, it can be
wall-mounted.
HI-DEF OPTICAL
Blu-ray
or HD DVD? That is the question. It’s
not going to be answered this year,
though, or probably next year either.
But consumers are finally getting their
chance to check out content that matches
the performance of their HDTVs.
Samsung’s BD-P1400 Blu-ray player
sports an HDMI v1.3 output in addition
to the usual DVI, S-video, and component
video outputs (Fig. 2). It delivers
1080p video streams with Dolby Digital
Plus and Dolby TrueHD audio. Also, it
handles 25-Gbyte Blu-ray disks plus standard
DVDs and CDs. The transfer rate is
36 Mbits/s. Upgrades are possible via an
Ethernet port.
Now in its third generation, Toshiba’s
HD-A35 is the quintessential HD DVD
player (Fig. 3). It can deliver 7.1 highbit-
rate audio over HDMI along with
1080p Deep Color video. Movies can be
shown at 24 frames/s, the rate at which
they were filmed. It’s also Webenabled
with an Ethernet connection
that can be used for
upgrades. With the right hardware,
the CE-Link HDMI-CEC
interface allows movies to be played
with a single button click.
While transmitted and diskbased
HD content is currently
limited, it is growing quickly. HD
DVD’s 15-Gbyte capacity isn’t
really an issue, since HD content
doesn’t fill even one of these disks.
ONE REMOTE TO BIND THEM
Universal remotes aren’t new, but the
latest crop is more than just buttons.
Pick up Logitech’s Harmony 1000
from its charging station, and you
notice the difference between it and
conventional TV remote controls (Fig.
4). It can be configured from a PC via
USB instead of via lots of button combinations.
Also, it can drive infrared
devices individually and in combination.
Its LCD touchscreen provides the
same kind of flexibility as Apple’s
iPhone as well.
