Cost-effective solution ready in time for autumn European launch
of digital terrestrial television

London, UK, May 14, 1998 - LSI Logic, the world's leader in
system-on-a-chip design, and the BBC, the internationally renowned UK
broadcaster, today announced the immediate availability of the L64780, a
jointly developed single-chip digital terrestrial television (DTT)
demodulator . LSI Logic and the BBC joined forces in June 1997 to develop
a cost-effective DTT solution for deployment in 1998. The chip received
both 2k and 8k modes, and decoded picture and sound from the BBC's trial
service broadcast transmitter located at Crystal Palace, London.

The design of the L64780 device was implemented by a team at the BBC's
Kingswood Warren R&D facility and by LSI Logic at its Paris Design
Centre. It was based on a hardware prototype initially constructed by the
BBC to run trials of the experimental DTT broadcasts in the UK and other
European locations. By applying its G10â system-on-a-chip technology, LSI
Logic has squeezed a 19 inch rack composed of over 20 programmable chips
originally used in the BBC prototype design onto one tiny piece of

The L64780 is fully compliant to the European Digital Video Broadcast
Terrestrial (DVB-T) standard of which the BBC and LSI Logic are members.
The DVB-T standard is suited to use in the 6 MHz, 7MHz and 8MHz channels
used in different parts of the world. The device supports all DVB-T
modes, including 2k and 8k carriers, and hierarchical modulation.
Tolerance to fast moving and difficult channels is achieved through an
innovative channel estimation algorithm working in both time and
frequency domains. In addition the L64780 seamlessly interfaces with low
cost tuners since common phase error measurement and compensation
algorithms were incorporated on chip.

"As a result of our joint development with the BBC, we are the first
semiconductor manufacturer to deliver a Right-First-Timeä, single-chip
DTT solution. This chip will enable TV and set-top manufacturers to put
cost-effective products in the hands of consumers in time for DTT
European deployment later this year," said Elie Antoun, Executive Vice
President of Consumer Products, LSI Logic.

"The BBC has been a pioneer in the area of digital television, and was
the first broadcaster in the world to have a digital terrestrial pilot on
air which complied with the European DVB-T standard. The BBC's expertise
in compression and modulation technology, combined with the integrated
circuit design skills of LSI Logic has meant that the development of the
L64780 has been an outstanding cooperative achievement," said Dr. Ian
Jenkins, Controller of New Technologies, BBC.

The L64780 is a single-chip Coded Orthogonal Frequency Division Multiplex
(COFDM) demodulator. The device is capable of delivering up to 31.7
Mbit/sec. With each service demanding typically between 2 Mbit/sec
(movies) to typically 5 Mbit/sec (mixed programming channels), several
program services can be offered in the
8 MHz channel previously filled by one conventional analog PAL channel.

The L64780 chip samples a low IF signal and converts it digitally into
baseband. The device then applies all digital processing steps to extract
the data from the received signal, such as FFT, timing and frequency
synchronization, channel estimation and equalization, generation of
optimal soft decisions using the channel state information, symbol and
bit de-interleaving.

"This is an outstanding example of collaboration. The BBC provided DTT
expertise and an intimate knowledge of the European broadcast market,
while LSI Logic provided the expertise to implement the BBC's DTT
expertise into working, cost-effective silicon. By working with the BBC
we have been able to deliver a highly integrated DTT system-on-a-chip
solution within a record one year," said Jean-Luc Droitcourt, Marketing
Director for Digital TV, LSI Logic.

L64780 samples, together with an evaluation daughter board for the
set-top box development platform (SDP) are available immediately. The
daughter board includes the L64780 device, software drivers and a tuner
module. LSI Logic has shipped samples and evaluation platforms to lead
customers. The chip is priced at sub $20 for volume purchase.

BBC company background
The BBC is a public corporation, set up by Royal Charter to provide
broadcasting services at home and abroad. The BBC's core home services
are funded by the television licence fee which pays for BBC-1 and BBC-2
which provide more than 12,500 hours of programs a year; national Radios
1, 2, 3, 4, and 5 Live; national radio services in Northern Ireland,
Scotland and Wales, including services in Welsh and Gaelic languages; and
38 English local radio services. The BBC World Service, the international
radio service funded by Government Grant-In-Aid broadcasts to 144 million
regular listeners a week in 45 languages, including English. The BBC
generates further revenue to support its home services by exploiting its
assets at home and abroad through its commercial arm, BBC Worldwide.
