Calibrating Leo Laporte's TVs with Robert Heron

Calibrating Leo Laporte's TVs with Robert Heron

Home-theater technologist Robert Heron and I discuss my calibration of Chief Twit Leo Laporte's two flat-panel TVs: a brand new, 65-inch Panasonic TC-P65GT50 and an older 50-inch Pioneer PDP-5070PU. Using a Minolta CS-200 colorimeter, AVFoundry VideoForge test-pattern generator, and SpectraCal CalMan software, the Panasonic measured quite well in THX Cinema mode, but I was able to tweak it even closer to the well-established video specs. The Pioneer does not offer calibration controls, so it came down to a choice between two color-temperature settings. See all the results here!

Smyth Realizer Headphone Surround Simulator

Smyth Realizer Headphone Surround Simulator

Lorr Kramer, vice president of Smyth Research, explains the Smyth Realizer, a sophisticated surround-sound simulator for use with any 2-channel headphones. This small device measures how sound waves from a speaker system in a room enter the user's ears, then simulates the sound of that speaker system and room—as heard by that individual—in a pair of headphones, including distance and direction of each speaker. This is a fascinating technology that goes well beyond other headphone-based surround simulators.

The Birth of Universal Remotes and the Darblet Video-Enhancement Processor

Paul Darbee, inventor of the universal remote control and the DarbeeVision Darblet video-enhancement processor, talks about both inventions, including how he came up with the idea of universal remotes, how they were intended to solve the problem of lost remotes as much as reducing coffee-table clutter, the DarbeeVision processing algorithms and how they behave like a super-sophisticated unsharp mask to add dimensionality to 2D images, answers to chat-room questions, and more.

Spectracal's Derek Smith Geeks out About Color Calibration

Spectracal's Derek Smith Geeks out About Color Calibration

SpectraCal co-founder and CEO Derek Smith explains the company's new Color Cube Calibration system in the Lumagen Radiance video processor and SpectraCal's CalMan 5 software, which uses the same type of lookup tables (LUTs) as those found in high-priced professional processors to adjust the colors produced by video displays. Unlike color-management systems in most consumer products, Color Cube adjusts the three primaries (red, green, blue) and three secondaries (yellow, cyan, magenta) at many different brightness levels, resulting is much more accurate color reproduction.

3D Pioneer Gene Dolgoff Explains New 2D-3D Converter and How the Brain Works

3D Pioneer Gene Dolgoff Explains New 2D-3D Converter and How the Brain Works

In the first of two related episodes, Gene Dolgoff, CEO and CTO of 3-D Vision and one of the most requested return guests on Home Theater Geeks, talks about his new 2D-to-3D converter box and how it works. He also explains how listeners could support the development of the product at www.fundable.com/3-dvision and submit their own design ideas for the outer casing (though that opportunity has now passed).
Run Time: 57:48

In Part 2, Gene discusses wave phenomena, Fourier transforms, and holography, and he explains how the brain operates holographically. This allows his 2D-to-3D converter to work very well while requiring less processing power than other systems, because your brain does much of the hard work. Deep stuff!
