Theoretically, the perfect gamma for a system from light entering a camera, to the display, then reaching our eyes, would be 1, since this would mean we were seeing the same ratios as the camera was receiving. Our current system was mostly built around CRTs which have inherent gammas approximately in the range...
Many surround sound receivers and processors these days offer an "Auto" set-up routine that attempts to configure the basic set-up for the consumer, including whether a speaker should be high-passed or not, which frequency to high-pass it at if applicable . . .
Recently I have had a barrage of e-mails from friends and readers asking why HDTV connectivity is so complicated. I found myself sending out the same advice and comments over and over, so I wanted to share some of this advice. DVI (Digital Video Interface) . . .
We were first introduced to this problem by Richard Ansell of Snell & Wilcox just a little over three years ago. Richard showed us the problem using an expensive boutique DVD player.
What we covered in Parts 1 and 2 are the most commonly looked at aspects of DVD players. In Part 3 we take a look at another area of performance that I believe has been seriously neglected by everyone, including us (up until now)...
One of the areas that gets short shrift from many DVD player reviews is the actual usability of the players. Sure, some reviewers talk about the layout of the remote, but only indirectly communicate usability issues...
It has long been our feeling that one can learn much more about the quality of a DVD player by watching lousy DVD movie material than you can learn by watching great material. Great material tends to look fine on just about every player...
On May 13 and 14, 2000, Secrets hosted its first DVD player Benchmark Event (Shootout I) in Redmond, Washington, where we tested numerous DVD players as to their video, audio, functional, and usability qualities. Audio Precision and Tektronix instrumentation were employed to gather extremely accurate data.
Let's start with a little technical information on DVD. I am never really sure how much to cover and how technical to get. I will do my best to make things as easy as possible for everyone to understand...
A machine can very precisely tell you quantitative information about an audio signal, but it can't tell you what that signal will necessarily mean to any given individual...
