The Development of HD Technology The earliest high-resolution experiments date back to the s and s , when resolution was measured in lines per screen.

But further development of analog HDTV was blocked by limited bandwidth. Television may no longer have the impact on our collective consciousness it did when you had a choice among maybe three channels and before there was an internet. Still, considering the extent to which TV still permeates our lives, it is really rather remarkable how little about it has actually changed: A TV set is still just a single-purpose appliance that shows scheduled programming in the privacy of your own home, for free despite persistent and questionable efforts to add phone calls and web browsing and e-mail to the platform.

TV is great because it's one of the original literally plug-and-play devices. And because no matter what time it is, there it is, waiting for you, in the words of legendary broadcaster Tom Snyder , to "fire up a colortini, sit back, relax and watch the pictures, now, as they fly through the air. But there has been nothing like the four-year national initiative to retool the nation's entire broadcast infrastructure which culminated in with the rollout of universal digital television.

It was this same kind of frenzy at the start line, but for entirely different reasons. The Panasonic television followed NHK's standards -- an analog signal that packed more information than traditional television signals. By the s, NHK had developed the technology to the point that it was time to shop around for other customers. It became clear that if NHK could convince the world to adopt its standards, Japanese television manufacturers would make a fortune.

Japan's advances in television broadcast technology coincided with a politically charged situation in the United States. If it weren't for a metaphorical game of tug-of-war between television broadcasters and companies invested in two-way radio communications, HDTV may not have made its way to the United States.

A battle raged in the United States during the early and mid s. On the other side was Land Mobile, a lobbying organization led in part by Motorola. Land Mobile's objective was to claim unused ranges of television frequencies for two-way radio broadcasts. The NAB wasn't eager to hand over these airwaves, claiming the radio communications would interfere with broadcast frequencies.

Land Mobile's argument was that the airwaves in question weren't being used for anything and were being wasted. He said that the unused airwaves could be used for high-definition broadcasts. Despite Fowler's response, several politicians saw the demonstration and were surprised to see such advanced technology come out of Japan.

But the lawmakers were determined that this would only happen under their own terms. The fear was that by adopting the Japanese standard, the United States would permanently position American television companies behind Japanese manufacturers.

The committee decided that the new standard would have to follow two rules: It would need to be analog and it couldn't negate the existing television broadcast technology. As the six contenders worked on their approaches to HDTV, there were a few interesting developments.

One was that the prospect of digital television became viable. When ACATS made the determination that the approaches should be analog, it was because the committee believed a digital solution wasn't feasible. But further consideration led to the conclusion that digital would be the future of terrestrial television transmission.

ACATS submitted each approach to extensive testing in a special facility designed specifically for that task. Two of the six proposals were analog approaches.
