configured this way can provide for extremely high-speed access
to both symmetrical and asymmetrical data services, as well as the
ability to evolve to even higher speeds and higher usage levels
through further segmentation of the coaxial "last mile" of the
network. Further, because analog and digital carriers using
completely different modulation schemes and protocols can coexist,
an evolutionary path is kept open for continuing advances in
digital services and technologies, while, at the same time,
allowing the pragmatic adoption of technology options to build
cost-effective systems today.
In building a hybrid fiber coax plant, the cable television
industry is providing a cost-effective, reliable, ubiquitous
transmission system that can simultaneously support many separate
networks, the sum of which makes the necessary upgrade investment a
sustainable one for any company in our industry. Time Warner, for
example, currently has plans to build at least four separate
networks on the foundation of its fiber-upgraded plant. Cable
Television Laboratories, an industry R&D consortium, is working
with a group of broadband equipment manufacturers to develop an
open standard that is called the Spectrum Management Application,
to allow the coexistence of these multiple networks and the
maximization of the efficiency with which the radio frequency
spectrum within the transmission plant is used.
In Time Warner's upgraded plant, for example, there are plans
for the coexistence, and separate operation, of networks that will
continue the broadcast of scores of analog TV channels and will
begin the delivery of high-quality digital telephone service, the
provision of high-speed personal computer interconnection service,
and access to a wide range of interactive video services. An
additional network designed for interconnecting PCS radio microcell
sites may be integrated into that residential network, or may be
operated independently.
Time Warner's personal computer interconnection services will
incorporate support of the Internet Protocol (IP), and they are in
the process of working with a number of companies that are
designing the necessary hardware and software systems needed to
provide a service of this type. Many companies in the cable
television industry envision initially offering access to a variety
of online service providers, as well as e-mail and direct
connection to the Internet at speeds currently unavailable to
almost anyone, anywhere. We do not pretend to know how the Internet
will evolve; there are those who claim that it will one day provide
video, shopping services, and all the rest. It is far from that
today and has many shortcomings, as recent security problems have
demonstrated. But regardless of whether PC interconnection
ultimately flows through a number of competing national online
services or through the laissez-faire anarchy of the Internet,
cable intends to offer a highly competitive avenue for local
residential and business access to any viable service provider.
On a separate front, the industry is just beginning to
understand interactive television services through projects like
Time Warner's Full Service Network in Orlando, and while this and
other trials are beginning to teach us a few hard-won lessons, it
is far too early to set the standards for technologies that are
still in their early innovative phase. We are, however
incorporating standards wherever we can, particularly for content
(MPEG, for example.) There will still be public policy questions to
be dealt with in interactive TV, but they should wait until the
technology and business mature at least to the point that such
issues can be intelligently debated based on information and
experience that we will gain from the trials that are under
way.
An example of the harm that government regulation can do is
evidenced by the so-called rate regulations that the Federal
Communications Commission (FCC) enforces on the cable television
industry. These regulations are over 600 pages in length and are so
complicated that the commission has issued corrections and
clarifications that total several hundred additional pages. While
many people think that these rules are just about the subscription
fees that operators may charge to a customer, they do not
understand that these regulations also directly affect whether or
not we can include the cost of a new piece of equipment or a mile
of fiber-optic cable in the cost of "doing business" and adjust our
rates to recover the expense. In fact, the top FCC official
recently replied, in response to a question about "upgrade
incentives," that upgrades are just a code word for rate hikes. Any
premature attempts to set either mandated technological standards
or regulations shaping business structure have the real potential
to slow innovation in a field that may have great future value to
American business and society. Such standards may be called for by
industries that have a stake in the status quo and wish to limit or
confine the directions that innovation may take, but these calls
must be resisted if the country is to benefit fully from the fruits
of the process of invention and exploration.
