In 1969 Japan's National Broadcast Network (NHK) started research on an advanced television system to bring truly high definition television to the public. Their goal for such an endeavor was to "appeal to a higher level of psychological sensation and emotion by transmitting highly intellectual information with detailed characters and graphics." 1
That highly eclectic goal for HDTV remained through its complex evolution to the US system commercialized in 1996. Unfortunately, that goal is being severely and continuously eroded by most of the purveyors of "HDTV." Granted, there are some HDTV offerings with quality of production and distribution levels reaching and perhaps exceeding that lofty NHK aspiration - but not many.
There are several reasons for HDTV quality reduction in the US broadcast distribution industry; that industry including OTA, Cable, DBS, et al. Indeed the pioneers of broadcasting - both in radio and television - such as Sarnoff, Armstrong, Farnsworth and others - were frustrated over the de facto applications of the media they labored so hard to create. The hope was that broadcast HDTV would rise to that higher, loftier level and deliver images and sound that would raise the sensual sensitivities of the viewers and ultimately mankind in general. But the economic forces that finance the commercial success of the system interfered, causing, hopefully, a temporary compromise in the quality of HDTV delivery. Interestingly, it took the NTSC delivery system almost 50 years to get it right. Then, along came digitization and the signals were up-converted, down-converted, reformatted, scaled, compressed, transcoded and "bit-starved" to force them down very expensive "pipes."
For those who just purchases new HDTV displays, it is possibly frustrating not to be able to see the high quality HDTV images they saw in the showroom, save for some sports and live OTA productions. Generally poor receiver upconverters create fuzzy SD images that are even more myopic when stretched to full screen.
So, is there any hope? Yes, there is - a bunch of hope. Allow me to summarize:
Consider the above bullet point a "call-to-action." I don't think we should expect anything less than the original NHK goal for HDTV. Without us, it may take another 50 years to get it right. But it will get at lot better.

Reader Commentary Mar 6, 11:01am You are absolutely right about the potential of the ATSC system we have put in place.

Obviously, the 625 should provid Mar 7, 7:05am I have yet to see the promise of HDTV since 2002.
