HD Waveform 10 - Dynamic Iris and Gamma

By Richard Fisher • Mar 26 2007, 6:28pm

The purpose of this article is to put that into perspective so that the performance enthusiast will understand why this feature degrades overall image performance, why it sells product and why, for some technologies, it may be needed to be competitive.

Ed's View - HDTV All the Time - The Amazing UMP

By Ed Milbourn • Mar 21 2007, 6:02pm

CinemaScope™ HDHT - Part 2

By Rodolfo La Maestra • Mar 6 2007, 7:52pm

As I mentioned on the first article, I decided to launch this CinemaScope™ project at my own cost and with my own design and equipment selection, to been able to publish a series of articles for the readership of our magazine, and to show consumers that this concept of a high-definition home-theater (HDHT) CinemaScope™ is economically affordable, technically possible, and could certainly be attractive to many 2.35:1 movie viewers.

Having completed the electronic and optical stages of the system in a dedicated room with controlled lighting, I can tell...
