LG Demonstrates Mobile DTV Chip at Wireless Show
LAS VEGAS: LG Electronics is demonstrating handsets with
mobile broadcast TV reception at the CTIA Wireless conference this week. The
vendor said it demoed three prototype cell phones with mobile DTV reception.
“In addition to these cell phones running on both the CDMA and GSM networks,
we’re also demonstrating how easy it is to receive mobile DTV on a netbook with
a plug-in accessory receiver,” said Ehtisham Rabbani, vice president,
marketing and innovation for LG Mobile Phones.
The LG handsets with mobile DTV include a CDMA phone with twin LCD screens; a
CDMA model with a 2.8-inch LCD screen and up to four hours of DTV-viewing
battery life, according to LG; and a GSM phone with a three-inch LCD screen
also with up to four hours of DTV time, the company said.
LG was integral in the development of the mobile DTV transmission standard and
has created single-chip reception technology. LG’s tuner/decoder chip is 7 mm
square, especially designed for integration into cell phones. This LG2161R
receiver chip is in pilot production and will move to mass production this
summer. The LG2161R includes both the radio frequency tuner and the mobile DTV
demodulator for reception and display of the mobile DTV signals now being
broadcast by 40-some stations
The LG2161R is said to have “improved channel changing speed from earlier
chipsets,” and “features enhanced reception performance.”
LG described its LG X300 netbook USB dongle receiver as weighing less than 990
grams, and featuring integrated WiFi and a 64 GB hard drive.
“Among the first products to reach consumers will be a variety of USB receivers
for mobile DTV, most of which are built around LG chips for reception,” said
Dr. Jong Kim, president of LG’s U.S. R&D lab, Zenith. “These low-cost
receivers can instantaneously transform a netbook, or laptop computer into a
mobile digital TV receiver with the addition of software that will come with
the USB device. LG is working with more than a dozen companies to
introduce mobile DTV products in the U.S. market.”
In a separate item, Grass Valley said this week that it has installed a new
mobile DTV transmission platform for PBS member station WGBH-TV in Boston.
TV Technology has coverage. The
publication’s Web site also has an article by transmission expert Doug Lung discussing
the mobile DTV standard tables.
“One thing I learned while putting together the MDTV demo at CES in January is
that MDTV, using IP transport, is quite different from A/53 "regular"
ATSC DTV using PIDs,” Lung writes in, “
