FROM MAY 2002 KCOS "VIEWER" By Craig A. Brush President, General Manager, KCOS-TV  

On May 1, 2003, just one year from now, KCOS is mandated by the federal government to begin operation of a new digital television broadcast operation. KCOS-DTV will operate on Channel 30 and its broadcast signal will only be seen by homes that have either new digital television sets capable of receiving terrestrial digital broadcasts or homes that have installed digital "set top boxes" that can convert digital signals.

The cost of converting to digital technology will be very expensive. In order to acquire a new transmitter, antenna, master control, and production equipment, the station will need to raise nearly $4million.

Fortunately, KCOS has already raised nearly $3 million toward its conversion to digital technology. Nearly $1.5 million of that comes from a grant from the Public Television Facilities Program, which is part of the United States Department of Commerce. As a condition of that grant, KCOS had to commit to providing matching funds totaling nearly $500,000. Toward that end, this month KCOS will launch its first Capital Campaign in the twenty-three year existence of the station.

The goal of this fundraising effort is to raise $1 million dollars to be used to help purchase equipment necessary for the digital technology and to establish a "Digital Future Fund" to help KCOS meet the financial requirements of digital operation.

If you would like information on how you can help KCOS meet its capital, and see your contribution matched by three dollars for every dollar you contribute, please contact me directly at (915) 747-6500.

Should KCOS fail to convert to digital technology, ultimately the station will lose its license to operate. Our long-term viability and existence depends on the success of our Capital Campaign and the generosity of the community we have proudly served for nearly a quarter of a decade.






What is digital television (DTV)?

The picture viewers currently receive is based on an analog transmission system that is more than 50 years old. In December 1996 the Federal Communications Commission approved the U.S. standard for a new era of television — digital television. In a digital system, images and sound are captured using the same digital code found in computers — ones and zeroes.

The digital revolution will not only dramatically improve the quality of the television picture, but also make possible the over-the-air delivery of several simultaneous services to viewers. This is due primarily to the three main benefits of the digital system: high definition television, multicasting in standard definition television and data transmission.

What is high definition television (HDTV)?

Digital television will allow stations to broadcast programs in much higher resolution or clarity than standard analog television. This is called high definition television or HDTV. Viewers at home will be able to receive high-quality, crystal-clear pictures. These visually stunning pictures, with more than twice the resolution and clarity of standard television, will be displayed in a wide screen format with a 16 by 9 width to height ratio compared to today's 4 by 3, or basically square format. And because HDTV is digital, audiences will have the benefit of six-channel CD-quality "surround sound." In other words, viewers will be able to enjoy a true home theater experience.

What is multicasting?

When not transmitting in HDTV, broadcasters will be able to transmit four or more channels of standard definition television (SDTV) programming simultaneously. This is called multicasting. Although SDTV will not match HDTV in quality, it will offer a higher quality picture than we have today.

What is enhanced digital television?

Digital broadcasting will offer an entirely new form of programming: enhanced digital television — the fusion of video, audio, images and text. For the first time, producers will be able to combine the story-telling power of video and film with the enormous data capacity of a digital television signal. Viewers will be able to simultaneously watch an enhanced TV production and, in the background, receive hundreds of megabytes of additional video, audio, text and images related to the program. Imagine your favorite PBS documentary accompanied by a companion CD-ROM, but with the content stored directly on your computer or in the memory of your digital set-top box.

Will consumers be able to watch digital television on their existing sets?

Only if they obtain a digital converter box. DTV information is encoded in a different way from the analog television signal and therefore will require a different kind of receiver. Manufacturers are developing converter boxes that will allow viewers to receive programs broadcast on DTV channels on their analog TV sets. However, in order to experience the full benefits of digital television, including HDTV, viewers will need new digital television sets.

When will I be able to receive DTV?

It depends on where you live. Some limited DTV service in the largest markets was scheduled to begin in late 1998. PBS will begin distributing to member stations its first national HDTV and enhanced digital programming began in November of 1998 during PBS Digital Week. (Several PBS stations representing a variety of market sizes began to offer a digital signal this in November.) However, public and commercial broadcasters in most markets intend to begin service between 1999-2001. Consumers will not be able to receive this initial DTV programming without a new set-top box, and will only be able to take full advantage of the enhanced digital video and audio quality and ancillary services when they purchase a new DTV-capable receiver.

Where can I see DTV?

DTV receiver demonstrations (and some early sales of new sets) already have begun in some retail stores in various parts of the country.
