Even for problems that makeup cannot easily hide, television's low resolution usually smooths the rough edges. Not so with high-definition TV. High-definition television broadcasts are the law of the land now. A scant few months after the digital switchover, a number of manufacturers and broadcasters are pushing 3-D TV, which would require a whole new upgrade cycle. No government mandate for this, so only the market will determine whether 3-D TV is the next great thing.
Follow us for disruptive tech news: John C. 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. These two, including a proposal submitted by NHK, faded away. There were no clear winners among the digital approaches. ACATS concluded that there should be a second round of testing. The four remaining competitors weren't keen on the idea of another round of expensive development and testing. As a result, the four remaining groups formed a consortium with several other companies called the Grand Alliance.
The Grand Alliance divided up the machine into several subsystems and assigned each subsystem to a specific group. ACATS approved of the standard and the path was cleared for manufacturers to market consumer televisions. The first HDTV sets hit the consumer market in Those sets came from manufacturers like Panasonic and Sony, and had a different appearance -- they were wider than standard televisions.
That's because the new HDTV standard also included a new aspect ratio. The standard aspect ratio was , the new ratio was If you had the cash to drop on one of these sets you might have been disappointed to find that there wasn't much programming available. Today, several cable and satellite companies offer high-definition content. But that's another story. You can offer your link to a page which is relevant to the topic of this post.

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.
HD Today HDTV uses a standard called p, which delivers a resolution of xp, equivalent to 2,, pixels per frame 2. Related posts:.
