LSI, Isreali Firm Working On
Video-On-Demand Chipset 11/16/94 TEL
AVIV, ISRAEL, 1994 NOV 16 (NB) --
Orckit Communications has announced a
technology deal with LSI Logic in the
US. According to the Tel Aviv-based
telecoms company, terms of the
contract call for both companies to
develop and market a dedicated
chipset for the emerging video on
demand (VOD) market.
According to Dan Arazi, vice
president of marketing for Orckit,
this chipset will allow systems
integrators and telephone operating
companies to offer their customers a
cost-effective VOD service over
existing twisted pair cable
infrastructures.
Orckit specializes in the design
and manufacture of core technologies,
as well as systems for high data rate
modulation/demodulation transmission
equipment.
According to Arazi, two
generations of products are being
developed at the same time -- they
both can support downstream data
rates of 6.144 Mbps (megabits per
second) which the company claims can
support three or four compressed
video channels working to VHS video
quality, as well as bi-directional
channel of up to 576 Kbps
(kilobits/second).
The first generation system
complies with the new ANSI (American
National Standards Institute) T1 E1
standard and meets the distances plus
specifications laid down, but uses
off-the-shelf DSPs (digital signal
processors), and is not optimized for
cost, size or power consumption.
The second generation of chips
will be based on the fully customized
LSI Logic ASIC (application specific
integrated circuit), which Orckit
claims will give a dramatic lowering
of the cost, size, and power
consumption of the equipment. This
chipset should ship towards the end
of the second quarter of 1995,
officials said.
So what do all these developments
mean for the VOD marketplace?
According to the company, the
development should allows vendors
developing VOD technology to source
dedicated and low-cost chipsets for
their system boards, rather than rely
on complex and expensive DSP-based
systems. This should cut the cost of
VOD technology hardware in the short
run, as well as the longer term.
