As you might expect, industry standards that
pertain to consumer electronics continue to evolve.
The word “standard” seems to imply something that
comes into being and then remains the same for many
years. Although there is some
truth in this, one would never
expect a fast-moving industry
like consumer electronics to
have standards set in stone.
At the 2009 International
CES, held last month in Las
Vegas, I had a chance to visit
with standards groups as
well as companies intimately
involved with those groups. I
learned about the updates to
several of these standards, and
they were impressive.
WI-FI ALLIANCE
Kelly Davis-Fellner, marketing director for the
Wi-Fi Alliance, filled me in on that
group’s activities. For example, 802.11n is still in draft
mode and may be finalized in January 2010. More
interesting, though, is the group’s efforts to connect
Wi-Fi devices anywhere, with or without a Wi-Fi
network available, a feature that’s long overdue.
Consumer applications include printing pictures
directly from a camera; sharing music directly with
a friend; displaying photos directly from a mobile
phone to a TV; and playing video games with friends
on different devices. Wi-Fi is late to the party with
some of these applications, but it’s good to know that
the group expects these features to roll out in 2010.
ZIGBEE ALLIANCE
On the ZigBee front, chairman
Bob Heile discussed the group’s Smart Energy
initiative. Ratified in May 2008, the ZigBee Smart
Energy profile was made publicly available last June.
It offers companies a secure, easy-to-use wireless platform
for developing products that enhance energy
management and efficiency for consumers. ZigBee
Smart Energy is being rolled out or used by a growing
number of utilities. More than 25.3 million meters in
North America are committed for installation.
Utilities and consumers can select from 20 certified
products representing a range of devices needed to
manage home energy consumption, including electricity
meters, thermostats, and in-home displays.
Tobin Richardson, director of the Smart Energy Initiative,
showed us a demo of how it all works for utilities
and consumers alike. You can view the video at

USB IMPLEMENTERS FORUM
Jeff Ravencraft, USBIF
president and chairman,
spoke about the latest innovation
for USB, namely Super-
Speed USB (see “Trailblazing
SuperSpeed USB Design And
Verif ication” at www.electronicdesign.com, ED Online
20506). The spec, which can
be found at www.usb.org/developers/docs, promises data
transfer rates up to 10 times
faster than Hi-Speed USB
(USB 2.0) with optimized
power efficiency to boot.
There are five new wires: two transmit, two receive,
and one ground. Jeff showed me the new 3.0 B plug,
which has a second level, compared to the previous
version (see the figure). The form factor of the A
plug—the one that connects to your computer—stays
the same. He also mentioned a new micro connector
family that would be used in consumer electronics
devices such as cell phones. And, note that the 3.0
spec adds more power for charging—900 mA.
WIRELESS HOME DIGITAL INTERFACE(WHDI)
I hadn’t planned on meeting with Leslie Chard,
president of WHDI. But he was in the Amimon suite,
smiling broadly at the giant strides WHDI has made
over the past year. I met with Amimon at the 2008
International CES, where it first showed this new
technology for wireless high-definition video connectivity.
This year, its suite was packed with people
viewing demos of the technology in action.
WHDI technology uses a video modem operating
in the 5-GHz unlicensed band for wireless delivery
of uncompressed HD video up to 1080p. It provides
secure, encrypted HD video delivery through multiple
rooms and other potential signal obstructions, such as
people and furniture, while maintaining high quality
and robustness with less than 1-ms latency.
At the show, WHDI announced that it will use
HDCP revision 2.0 (High-bandwidth Digital Content
Protection) as its content protection technology.
The group also announced that LG Electronics will
be joining the WHDI special interest group (SIG).
Current members include Amimon, Hitachi, Motorola,
Samsung Electronics, Sharp, and Sony.
