TV Industry Works To Iron Kinks Out Of HDTV Technology

By: Emily Sanderson

While HDTV definitely has a lot of promise, it turns out that there are a lot more problems to be ironed out when it comes to providing it to viewers than most people would have thought. The first problem that the technology experienced, at least from the standpoint of viewers, was the number of channels available. When HDTV sets first came on the market, there just weren't enough channels that were dedicated to providing HDTV programming available to motivate consumers to buy HDTV set in order to watch them. In fact, for a long time (and maybe even continuing into the present) many consumers weren't even aware of what HDTV is. These people have largely been oblivious to the fact that HDTV is a TV format rather than a type of TV set, and have therefore had a lot of misconceptions about what HDTV sets are supposed to be used for.
The misconceptions about HDTV technology are actually an interesting study in what people will assume to be true when they don't have enough valid information. For example, without any awareness of the existence of HDTV programming, many people assume that HDTV sets are meant to display programming in wide screen format. After all, HDTV sets have the same aspect ratios of the contents of DVD's in wide screen mode and an increasing amount of normal TV programming.
The misconceptions extend to mistaking digital TV for HDTV, and by extension confusing the contents of normal DVD's with HDTV. These people are confused by the fact that digital TV is often referred to as DTV and that it provides a sharper picture than analog TV. They assume that since HDTV and DTV sound alike and DTV has a clearer picture than they're used to, that DTV is HDTV. These people are also intelligent enough to know that the video that standard DVD's produce is digital TV as well, so therefore DVD's must produce HDTV. Unfortunately none of this is correct.
Now, despite the fact that the damage has already been done, there are a lot more HDTV channels available. This is definitely a good thing as far as supplying a lot of owners of HDTV sets with plenty to watch, but TV service providers apparently haven't figured out how to provide the increased load of HDTV channels very reliably. The high resolution picture of HDTV comes at the cost of making it a much more data intensive TV format, and the more intensive the TV format the more bandwidth it takes up. Since TV service providers don't have an infinite amount of bandwidth, they've had to make compromises with HDTV programming and those compromises show when watching it. HDTV viewers using several different TV service providers report problems with displaying HDTV programming. This problems include pixelating of the pictures, the video stream suddenly stalling, and the sound being out of sync with the the video. All of this probably has something to do with the video compression codecs that the TV service providers are using in order to compress the HDTV channels so that they don't take up as much bandwidth during transmission.
While all of these problems are annoying and inconvenient in the short run, there's little doubt that TV service providers will iron them out over time.
