CinemaScope™ HDHT - Part 3 - Screens and Aspect Ratios

By Rodolfo La Maestra • Jun 27 2007, 10:23am

If your HDTV has a fixed frame, such as an LCD/plasma panel or a rear-projection TV, and you want to see the CinemaScope™ image at its intended aspect ratio, there is not much that can be done about the bars at the top and bottom of the screen. As a result, the bars use part of the valuable vertical resolution of the 16:9 TV or the projector's chip. To make things worse some technologies, such as LCD projection, show the black bars as dark gray, distracting the viewing of the actual image.

The HD chip of a front projector is fixed to the resolution of its design (720px1280 or 1080px1920 pixels). Many projectors today are chip-based DLP, LCD, and LCoS technologies at 720p resolution. More recently, several affordable 1080p projectors were introduced to the market.

DirecTV - The March to 100 National High Definition Channels

Unless you've been under a rock, or subscribed to Cable, you are likely intimately aware of DirecTV's promise of having 100 national high definition channels in service by the end of 2007. Sounds good, doesn't it? 100 National channels of HD content! As you might imagine, this raises more than a few questions. Some of the more frequent ones I've heard are:

  • What channels will these be?

  • Will {insert favorite channel here} be among them?

  • How will they carry 100 HD channels if there aren't 100 networks with HD content?

  • How much will this cost me?

Ed's View - A New Light

By Ed Milbourn • Jun 1 2007, 3:35pm

As I have expressed many times in my various articles, I am not a fan of rear projection HDTV, least of all being the single panel DLP variety. Oh, yes, one can get from such DLP applications a bright, high-contrast image with definition a little bit better that SDTV, but certainly not HDTV. That added with the spinning color wheel with its whirling noise, motion artifacts, and poor (very poor) color tracking makes a mockery out of the perceived "definition" of HDTV.

But, now, there is new light shining...
