(Nasdaq: ADCT ADCT Adaptive Discrete Cosine Transform ; www.adc.com) today announced the receipt of orders exceeding $1.2 million from public television stations for new Digital Television (DTV) transmitter systems. These orders, from three full service public broadcasters, show the commitment of PBS PBS

Private, nonprofit U.S. corporation of public television stations. PBS provides its member stations, which are supported by public funds and private contributions rather than by commercials, with educational, cultural, stations to lead the way in bringing DTV to the public as quickly as possible.
Louisiana Public Broadcasting Louisiana Public Broadcasting (LPB) is a state-run, viewer-supported network of PBS member stations serving the state of Louisiana. The network is operated by the Louisiana Educational Television Authority. purchased ADC's 800 Series solid state transmitter for WLPB-DT in Baton Rouge, La. According to Frank Kleinpeter, director of engineering for the company, "Our research showed that the ADC product offered a very clean, simple and straightforward design. This is important to us since functionality and reliability are key requirements for our DTV system."
Detroit Public Television chose ADC's Visionary(TM) DT Series inductive output tube The inductive output tube or IOT is a variety of vacuum tube which evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers. The primary commercial use of IOTs is in UHF television transmitters, where they have mostly replaced klystrons transmitter for WTVS-DT in Detroit. "We're pleased with the transmitter package that ADC has put together for us," said Helge Blucher, vice president of engineering and technology for Detroit Public Television. "It is important for public television to be available in a digital format as soon as possible to the people we serve so that we may begin developing its many future uses. We are confident that ADC's transmitter system will serve us well in meeting this goal."
Serving Allentown, Pa., Lehigh Valley Public Television has chosen to upgrade its aging analog transmitter at WLVT to a digital-ready unit, while adding the new DTV system for WLVT-DT. "Prior to this purchase we visited ADC's plant in McMurray, Pa. to evaluate the product," said Gil Aykroyd, director of engineering for WLVT. "We were very impressed with the quality of both the product and the manufacturing facility. Also, since we wanted to avoid the complexity of water-cooled systems, ADC's experience with air-cooled, high-power amplifiers helped us feel very comfortable with our decision." The WLVT package includes both a digital-ready Visionary(TM) analog unit as well as a Visionary(TM) DT digital transmitter.
"These orders demonstrate the high level of confidence broadcasters have in ADC's products and our proven ability to bring these broadcasters into the Digital Television era," says Dave Neff, vice president of ADC's Broadcast Systems Division. "We believe that our strong focus on the customer and our experience in deploying these systems will benefit these broadcasters. ADC will provide them the foundation they need to deliver the exciting services offered by this new technology."
Other public DTV stations which have recently begun broadcasting with ADC's transmitters include KTCI-DT serving Minneapolis-St Paul, Minn. and KRMA-DT serving Denver.
