Background Information

The Federal Communications Commission, in April of 1997, issued rules requiring all television stations to convert to a new digital broadcasting standard. KOIN began digital transmissions on December 17, 1999.  Congress later set February 17, 2009 as the last date for analog television transmissions.  After that date all full power television stations must turn off their analog transmitters.

The new digital television system adds significant new capabilities to television broadcasting, including:

• High Definition Television -- with a wide screen theater-like picture that is significantly sharper and doesn't suffer from the many problems of the current analog television system. The audio accompanying the picture will be in Dolby Digital Surround Sound.
• Multiple Programs -- Several 'standard definition' programs can be transmitted simultaneously. The digital system will bring an end to the noise, interference and color changes, which are common today. The digital picture received will be of the same quality as it was produced.
• Data Transmission -- Using space left over from television transmissions, up to 1.5 megabits or more of data can be transmitted to home computers or future smart TVs.

By combining all of these capabilities, a much enhanced and potentially very interactive family of programs can be developed for viewing with the digital system.

As the interest in Digital and High Definition television has increased so has the amount of programming that takes advantage of the technology. All of the film originated 'prime-time' programs on the CBS Network are being presented in HDTV as are most sports events. CBS also broadcasts the daytime drama 'The Young and the Restless' and ‘Late Night with David Letterman’ in HDTV. This adds up to more than 30 hours per week of HDTV programming being provided by CBS and KOIN-DT.

In order to begin digital broadcasting, every television station had to build a second digital television station while continuing to operate the analog stations. Broadcasting transmission facilities were generally not designed for this type of expansion, so replacement towers and buildings were required by many stations. Because of the huge expense of these facilities, stations have gotten together to build shared facilities and reduce the number of new towers needing to be built.  KOIN-DT shares its facilities with the digital transmissions of three other DTV broadcasters.
