July 8, 1999 (SEOUL) -- Samsung Electronics Co., Ltd. said it has developed a single
chip designed to receive digital TV signals.
Samsung's chip for digital TV is also available in digital set-top boxes and PC digital
cards.
"We minimized the number of parts to one from the previous two chips," said a
Samsung official, adding that the chip has an embedded digital transmitter that
digitizes analog signals.
The improvement will lead Samsung to lower chip prices, the company said.
Market watchers expect global digital TV demand to grow to US$700 million in 2005.

SEOUL -- Samsung Electronics Co. here today announced the
development of a new digital TV receiver chip that performs
analog-to-digital conversion and restores digital signals with error
correction for high-quality sound as well as high-definition images.
Samsung said it began development of the second-generation channel
device in May 1998 to serve the emerging market for consumer
products that receive digital TV broadcasts from television stations.
The new channel chip replaces the need for a two-chip solution,
according to the Korean company.
In addition to receiving and restoring digital signals from the tuner, the
new device eliminates dynamic multi-path impairment, which
Samsung said has a major impact on a digital TV's reception
performance. The channel chip is capable of receiving signals from
the set's tuner and processing it to regenerate the same quality as it
was when the signals left the broadcasting station, according to
Samsung.
With digital and analog TV broadcasts often used "side by side" in
broadcasting, analog signals can interfere with digital signals, noted
Samsung. The new channel chip is designed to eliminates
analog-signal interference and corrects any errors in the digital signal
that occur during transmission.
The channel chip is aimed at a range of products, including digital TV
sets, set-top boxes and add-on cards for personal computers.
Samsung said it expects to sell the channel chip at about $30 to $40
each when it reaches volume shipments. |
