More, on the DTV Transition

The first thing I want to say is that I am impressed at how our industry has stepped up to the plate to run tests and attempt to help get people in the state of Oklahoma ready for the transition. From local stations running their own tests, to the coordinated tests arranged by the OAB, OETA and the SBE, broadcasters in this state have come together in order to insure that a majority of the people in Oklahoma communities have an opportunity to learn what is required to make the DTV transition as smooth as possible.

The DTV Transition

Mike "Crusty" Johnson

I don’t remember exactly what year, but at sometime between 1978 and 1981, the Japanese television industry implemented a high definition television system with 1125 lines of vertical resolution. This was an analog system, was very expensive and, compared to NTSC, PAL and SECAM, required a very wide bandwidth. The NTSC system, used in the U.S. and several other countries, utilizes and is authorized a total bandwidth of 6 MHZ.

I’ve been studying electronics since I was 15 years old. And I’m still learning. When I started in electronics, TV sets were manufactured using exclusively vacuum tubes and discrete components. The typical radio was manufactured with vacuum tubes, as were the so called home entertainment systems with phonograph and/or reel-to-reel tape machines. Hi-fi audio was introduced, when I was in junior high school, and stereo audio was introduced before I graduated high school. NTSC color TV was introduced, in 1954, but there was no color TV in my parent’s home, until 1963.
